That economist can; Answer my question. I am not interested in this major. Thank you very much ~ Don't ask your husband with heavy eyebrows, is thrush fashionable? This poem is quoted here to show that China has a long history of women's makeup. Of course, not only from the Tang Dynasty to today. Make-up has developed into an industry and has become the strongest voice in the era of beauty. Let me review the beauty industry yesterday and try to explore the first part of this industry road today and tomorrow: the analysis of the present situation of the beauty industry and an overview of the industry problems. With the further deepening of China's reform and opening up, in addition, in the past twenty years, with the rapid development of China's economy, the living standards of China people have also made a leap, especially in some modern big cities (such as Beijing, Shanghai and Guangzhou). People's consumption level and consumption consciousness in beauty are gradually in line with the international advanced countries, and this consumption consciousness and mode are radiated to the surrounding areas and even large and medium-sized cities in China, so the beauty industry market is gradually growing in China. The consumption of beauty industry is becoming more and more mature. The beauty industry in China is in full swing. Huge business opportunities make the annual investment in the beauty industry as high as 60 billion yuan. According to statistics, the number of employees in the domestic beauty industry has reached 1 1 10,000, and the total output value of the beauty industry is as high as160 billion. The business opportunities contained in this huge market are the focus of attention of every investor.

Experts predict that in the next five years, the beauty industry, as one of the most competitive industries in the service industry, will leave investors with a market space of up to 500 billion yuan every year. However, judging from the development trend of foreign beauty industry, comprehensive club-style beauty places are the inevitable trend of development. Therefore, investing in such clubs in China is undoubtedly the best way to enter the beauty industry at present, as a beauty industry that originated from traditional service projects. The depth and added value of its services have great expansion and imagination, and it is also its profound service background that makes it pay great attention to modern new consumers, thus generating strong consumption desires and expectations. Generally speaking, the higher the expectation, the higher the dissatisfaction rate of consumers, which requires the beauty industry to start from a high starting point. Face the challenge with a high attitude, but the reality is not satisfactory. The management system needs to be improved, and the national market needs to be adjusted. The management system of the national beauty industry has not yet formed, and the corresponding laws, regulations and industry norms are almost blank. Industry and commerce, taxation, health, price, technical supervision, public security, fire protection, labor and social security and other departments are in charge of management confusion. Industry management is still hollow. In the development of the beauty industry for more than 20 years, the management of the industry is lagging behind and the management is loose and disorderly, which is in sharp contrast with the rapid development of the beauty industry. 2. The market order is chaotic. There is no service technology appraisal and access institution in domestic beauty industry. Service items are not standardized, service quality is not guaranteed, qualification names and technical names are confused, consumers can't tolerate products correctly, and legitimate interests can't be effectively guaranteed. 3. The functions and functions of trade associations are not obvious. With little effect, trade associations at all levels cannot fully undertake the historical mission of "perfecting, standardizing, promoting and promoting" the development of the industry. There are many associations, decentralized management and narrow activities. How to establish and improve the management system and operation mechanism of the association, and how to cooperate with relevant government departments to formulate standards and norms as soon as possible, all need to learn from other trade associations and improve and develop in constant exploration and practice. 4. Short-sighted business behavior and opaque industry operation. The integrity of the industry is relatively low. The problem of integrity in the beauty industry is more prominent, and social integrity is still at a low level. The integrity of the beauty industry lacks binding force on society and industry. False propaganda and false speculation are more common, which damages the interests of consumers to a considerable extent. At the same time, it also damaged the reputation of the industry and interfered with the normal market development order. 5. The quality of employees needs to be improved. Compared with the rapid development of the industry, the development level of vocational education is obviously slow and the quality of employees is obviously uneven. High school education below technical secondary school accounts for nearly 90% of the total number of employees. Vocational training time is obviously insufficient, training standards need to be improved urgently, high schools and low posts need to be redistributed urgently, and highly educated talents need to be introduced urgently to improve the quality of the whole industry and provide more advantageous services. The operation of this industry is still opaque. At present, the beauty industry mainly relies on beauty salons as sales terminals to enter the consumer market. Other beauty places, such as fitness centers and rest clubs, have little effect and have not had great influence. Beauty institutions with chain capabilities have obvious regional characteristics and have broken through boundaries and national boundaries. The beauty product sales terminal enterprises that can resist the banner of the beauty industry have not really formed the second chapter. Beauty economy needs rational rules. The biggest attraction of the beauty industry lies in the psychology of consumers seeking beauty. The outside world calls the beauty industry beauty economy. Although this title is not comprehensive, it proves from another angle that the beauty industry will embark on the most dynamic industry after tourism and the expansion of Zhang Zhilu. So what kind of rules does such an industry with great commercial potential need: 1. Professional ethics needs to be ahead of industrial development. Morality is the most basic social requirement for people, and it is also the basic element that constitutes the code of conduct for people. It is not only the expression of people's quality, but also the minimum requirement for adjusting social relations. For the beauty industry, professional ethics not only represents the development direction of the industry, but also determines the length and strength of the vitality of the industry. Especially in the current situation of high professional requirements and low quality of personnel, there is a good professional ethics requirement to adjust the basic behavior of employees in the beauty industry. It can lay a good development environment and a bright future for the beauty industry. 2. Adjusting the beauty industry and its development content will be further incorporated into laws, norms, laws, regulations and industry rules, which is a necessary means to standardize the development of the industry and make it healthy and sustainable. The rapid development of the beauty industry inevitably needs a set of reasonable and effective normative and legal documents to adjust its development, so that the interests of the national collective and individuals can be greatly guaranteed and all interest groups can be satisfied to the greatest extent. At the same time, to promote industrial and social development, as the fifth largest economy, the state and society must attach importance to the legal construction related to it, so as to guide the direction of industrial development, improve the industrial structure, and make the beauty industry grow along a standardized, reasonable and legal road. 3. Strengthen the adjustment ability of trade associations. Under the premise that the human and material resources of relevant government departments are insufficient for in-depth supervision, relevant government departments should make full use of social resources. Guide the beauty industry to establish a truly authoritative industry association, with the industry association participating in the industry management, and the government playing a good role as a referee in the middle, and establish a sound management mechanism: it can entrust the industry association to formulate industry standards, clarify all the service items and contents of medical beauty and beauty salons, and formulate operational industry standards and formulate new standards in time according to the emergence of new beauty projects. Ensure that standards and service items are basically synchronized, strengthen industry self-discipline and give play to the role of industry associations. Trade associations regulate the language of beauty advertisements according to advertising laws and regulations, and advertisements with service effects must be confirmed by trade associations. 4. Nanjing and Ningbo are the first in the industry to subdivide the level and business content. It is believed that this practice will rapidly develop into a set of perfect industry grading standards in a certain period of time. Different grades of beauty salons will bear different social responsibilities, enjoy different social trust and obtain different social benefits. As the consumer's consumption trends and trends become more and more distinct, businesses and products will continue to be subdivided. For different levels of consumption and different types of consumption, in addition to paying attention to the product itself, the requirements for price, level and level are also very high. In product line setting, enterprises and products will fully consider all their target consumer groups, so that their consumers can quickly find the required products among many products and services. Successfully completed the docking of consumer psychology. The third part is the new performance of the beauty industry in 2006. Development trend of beauty industry in 2006: The Interim Measures for the Administration of Beauty and Hairdressing Industry, which was implemented from 1 in 2005, formally put forward requirements for the standardized development of the industry. After more than a year of practice and implementation, the development of the industry has basically begun to develop and improve to the discovery standard, but many problems, including old problems and new concerns, have yet to be solved. Generally speaking, 2006 is a year full of opportunities for the beauty industry to move towards standardization and large-scale expansion. From the issuance of the first direct selling license to the reshuffle and stable development of the domestic and foreign market share, it indicates that the spring of the beauty industry in 2006 is still there. The development prospect of beauty industry is promising. Beauty service and beauty education will enter a new page. 1. The pilot of direct selling from walking to running, Avon's successful transformation and the first official license of domestic direct selling have made the direct selling model take a big step from groping walking to running. Many large cosmetics manufacturers are eager to try and even start to establish their own special sales channels. 2. The scale of franchise chain, the product market occupies a centralized and primitive traditional beauty shop, and now it has gradually begun to develop into a chain operation with scale effect, which has also become a magic weapon for many big-name enterprises to enter the market. It will be more and more difficult for small shops to survive and unite various resources in the face of shuffling, and to develop and grow with their own advantages. It will become the rules of the game in the beauty and hairdressing industry in 2006. 3. The beauty of a man will soon fill the vacancy. Although the cake of men's beauty has not been made solid and stable, the exploration space is still very optimistic. In cities with more white-collar workers, such as the Pearl River Sanjiao, Yangtze River Delta, Chengdu-Chongqing, Beijing-Shenyang and other places, the starting point of men's beauty salons is relatively high. From hardware facilities to beauty products and software, their price grades are much higher than those of women's beauty salons, and their operating conditions are very stable and their development momentum is very strong. Moreover, most men can accept the membership model, and their consumption concept is constantly improving. 4. The rapid expansion of marginal industries and the development of beauty industry will inevitably lead to the emergence of beauty culture, thus driving more industries related to beauty industry, including training, exhibitions, conferences, sales systems, etc. As a result, between industries and related industries, the closer the industrial chain and related industrial chains are, the more employment opportunities and opportunities to create wealth are in front of people. 5. The beauty education industry publicizes its position and highlights its important role in training and improving the service quality of the industry. In fact, the beauty education industry is also a branch of the beauty marginal industry, but its importance determines that its development must be unique. It will surely shoulder the heavy responsibility of creating a living environment for the beauty industry and opening up a bright future for the beauty industry. Although the development prospect can be expected, the free and high-speed development of the industry will always face policy risks brought about by market norms. In order to avoid risks, we must take the road of standardization and put the healthy and orderly development of the industry into an important issue to solve the bottleneck of the industry. No matter how big the capacity of the beauty market is, no matter how strong the beauty economy stimulates the sales terminals, as practitioners, we must realize that there is still a long way to go to standardize the market and operate according to the rules of the game-the future development trend of the industry-comprehensive analysis of 3D display technology (Figure) 2009-02-19/kloc-0: 46

After the Spring Festival, Samsung and Ubisoft combined with NVIDIA's latest 3D stereoscopic technology to launch a new 3D LCD (see "Game Vision Revolution Ubisoft Releases the World's First 3D LCD" and "What's the difference between pictures?" ? Samsung 3D display is the first test in China), many netizens began to have a strong interest in these two 3D displays, and triggered a new wave of 3D display craze.

In fact, 3D display technology is not the first time to meet with consumers. Before the release of Samsung 2233RZ and ViewSonic VX2265wm, many devices supporting 3D display came out, but they used totally different 3D display solutions. Many manufacturers have introduced 3D displays.

In fact, as early as ten years ago, the prototype of 3D stereoscopic display technology has been developed to realize the effect of displaying 3D stereoscopic images on 2D display devices. In the following time, many manufacturers have launched their own 3D display solutions, which are quite different in display principle and actual effect. Most 3D technologies need the help of special glasses.

After Samsung and Youpai launched 3D monitors respectively, some netizens disagreed, thinking that they used the same 3D technology as before. But this is not the case. Next, we will introduce several common 3D technologies and look at the advantages and problems of various 3D display technologies. Second, the overall classification of 3D display technology ● The overall classification of 3D display technology

In the early days, people needed to wear special glasses to see the 3D stereoscopic effect, whether using monitors or big screens in cinemas. However, with the continuous progress of technology, some manufacturers have introduced display devices that can observe stereoscopic images without wearing 3D glasses. So generally speaking, 3D display devices can be divided into two categories: those that need to wear 3D glasses and those that don't. Next, we will introduce these two technologies one by one. First, let's look at naked-eye 3D technology without special glasses. Samsung's large-size 3D display without special glasses.

At present, many display manufacturers, including Samsung, have introduced display devices that can see 3D stereoscopic images without wearing professional glasses. Their biggest advantage is that people can experience the immersive effect without wearing glasses at all. Imaging mode of 3D display technology without special glasses

This technology is generally called "naked-eye multi-viewpoint" technology, that is, the left and right eyes see two different parallax images from the display screen without any tools, and reflect them to the brain, so that people will have a three-dimensional sense. It also uses the parallax principle of human eyes to send different pictures to the left and right eyes of the viewer, thus achieving a three-dimensional visual effect. Because they can be observed without glasses, these technologies are very suitable for large-screen displays displayed in public places and are convenient for many people to watch.

However, the shortcomings of naked-eye 3D display technology are also very obvious: when people watch the screen, they must be within a certain range to observe the stereoscopic picture. If the distance from the screen is too far or the viewing angle is too large, the 3D effect will not be obvious. In addition, if the distance from the screen is too tight, people will feel dizzy obviously, so this technology is not suitable for small-sized displays for the time being. In addition, the display effect of this technology is relatively poor.

Recently, Kodak announced the launch of a new naked-eye 3D display technology. Different from the above, this technology released by Kodak uses two high-definition LCD screens with wide viewing area and virtual images. This desktop monitor has a viewing area of 45× 36 and a resolution of 1280× 1024. But this technology is used to make video games, molecular and chemical models and many other aspects, paying more attention to professional users. Three Traditional 3D Stereo Film Imaging Principles

Due to the factors of display effect and size, most of the current 3D technologies are assisted by special 3D glasses, so that 3D technology can be applied to small-sized desktop LCD monitors and the effect of 3D images can be ensured. ● The imaging principle of traditional 3D movies.

I believe that most readers first came into contact with stereoscopic images and enjoyed 3D movies in cinemas. Readers who have personally seen three-dimensional movies know that if you take off your glasses and watch them with the naked eye, you will find that the picture of the movie is very blurred, as if it is composed of two different images, and this phenomenon will disappear after wearing glasses. Why? When you don't wear 3D glasses, you usually see a blurred picture.

The light in the movie screen appears in the left eye and the right eye respectively through the selection of light by stereoscopic glasses, which makes the human body feel like a stereoscopic image. Technically speaking, 3D stereoscopic movies generally adopt two imaging principles. One is red and blue filter imaging technology, which requires special red and blue filters to watch. The other is polarized light filtering imaging technology, such as IMAX movies, which can only see the stereoscopic effect with polarized glasses. 3D glasses with red and blue filters

Let's take polarized light filtering imaging technology as an example. When shooting stereoscopic movies, we use two cameras to shoot images of the scene from different angles at the same time. During screening, two sets of films shot by two cameras are simultaneously screened by two projectors with polarized lenses, so that these slightly different images overlap on the screen. The light output by the film projector becomes polarized light after passing through the polarizing lens, and the polarized glasses used by the audience are actually a reduction process.

For the red and blue filter imaging technology, this technology will not be limited by the existing imaging equipment, as long as a pair of red and blue filters are matched, you can experience the 3D stereoscopic effect. When playing a movie, the stereoscopic effect is actually realized by interpolation. These two technologies are common in public places such as cinemas. Four 3D display imaging principles (1) ● 3D display imaging principles

The 3D principles we introduced before are mostly used in public places and cinemas. In addition, there are many 3D technologies for personal display devices. The principles of these technologies are roughly the same, and they are generally divided into two parts: active 3D imaging and passive 3D imaging. Most manufacturers use passive 3D imaging as a solution. The 3D LCD introduced by iZ3D adopts passive 3D imaging.

First, let's look at the principle of passive 3D imaging. Many desktop 3D displays adopt this scheme, and the principle is basically the same, such as the 3D LCD introduced by iZ3D. Imaging principle of three-dimensional image

As can be seen from the above schematic diagram, the reason why the human eye can see 3D images can be simply understood as that the images are transmitted to the human eye through horizontal interleaving and twists and turns, and then rearranged and combined into 3D images by the brain. 3D glasses can be regarded as a polarizing film, and the picture must be processed before passing through the first polarizing film. Adjust the image processing by using the plug-in loaded in the graphics card driver.

This technology only needs a 3D display and special glasses to realize 3D images, but its game resolution is relatively low and the number of games supported is very limited. 5. Imaging principle of three-dimensional display (2)

In addition to the passive 3D display described above, we will introduce the active 3D display next. Both Samsung 2233RZ and ViewSonic VX2265wm have adopted this solution. These two LCD monitors must be supported by NVIDIA 3D stereo technology to present 3D images. What kind of technology is 3D stereo? Why do people have to watch a 3D picture on an LCD with a refresh rate of 120Hz? The working principle of NVIDIA 3D stereo technology

NVIDIA 3D stereo technology does not increase the 3D performance of the graphics card, but it will not bring too much burden to the graphics card. By installing the latest driver, we can realize this technology on NVIDIA GeForce 8600GT or higher graphics card, and watch 3D images on LCD through NVIDIA's special 3D glasses. NVIDIA's 3D glasses set

Similar to previous 3D display solutions, we still need to wear special 3D glasses to see 3D stereoscopic images. Description of 3D imaging: The left and right eye signals are frequently switched, and a 3D image is formed by human brain calculation.

NVIDIA 3D Stereo uses page turning to achieve 3D effect in 2D environment. The working principle of picture exchange is to interactively display the left and right eye images on the screen, cooperate with special stereoscopic glasses, and use vertical synchronization signal as shutter switching synchronization signal to achieve the purpose of stereoscopic imaging. The left-eye and right-eye images (images separated by vertical synchronization signals) are transmitted to the left-eye and right-eye display devices respectively through the liquid crystal display, so that we can see a complete 3D stereoscopic picture. According to this characteristic, if we don't wear special 3D glasses or cover one of our eyes, we won't see the stereoscopic effect of 3D. In addition, NVIDIA technology also supports multiple pairs of 3D glasses to work at the same time, allowing users to play 3D games with friends and relatives.

The advantages of this 3D scheme are good picture performance, high game resolution, good compatibility with most 3D games at present, and switching between 2D and 3D pictures at any time. However, the disadvantage is that only graphics cards and glasses with NVIDIA graphics chips can be used to output 3D images. Six other 3D display technologies

What has been described above is our common 3D display technology. With the continuous development of science and technology, many manufacturers are developing new 3D display technologies. Below, we will briefly introduce it. ● Lens 3D liquid crystal display technology

This technology was jointly founded and directed by Philips and Sharp. It doesn't need glasses. It forms an image on this layer of convex lens array by adding a lens array on the topmost liquid crystal. Among them, each lens is placed at a small angle with the liquid crystal pixels and corresponds to seven liquid crystal cells, and each liquid crystal cell consists of three liquid crystal cells, which has the function of presenting three colors of RGB. In addition, according to a special algorithm, different colors are formed in the liquid crystal box, and finally an image is formed, so as to ensure that the left and right eyes of the viewer form different images, thereby seeing a realistic stereoscopic effect. The disadvantage is that if the viewing angle of the liquid crystal is different, because the role of the barrier is weakened, and. ● DFD stereoscopic display technology

DFD(Depth-Fused 3D) is a depth-of-field integrated stereo imaging technology developed by NTT in Japan based on a brand-new illusion principle. It uses two liquid crystal displays and half mirrors to display stereoscopic images, which can be viewed without special glasses. This stereo imaging principle is called reality. The process of making real stereoscopic images is to shoot images with general cameras, cameras, flashlights, etc. Then take the gray difference between the images taken by ordinary photography and flash photography, and compare it with a certain peak to get a binary image (the numbers are unified as 0 and 1), then extract the so-called near-image field, and finally add the relief depth of field to the near-image field. The shape of the depth of field of the object is different to some extent except that the sphere is close to the real depth of field. As long as the relationship between the near image and the far image is correctly maintained, the depth of field is continuous and smooth, and the texture is usually used for correction, a very harmonious stereoscopic image can be obtained. Samsung's 3D OLED panel for mobile devices ● Mobile 3D display technology

In addition to desktop monitors, the display screens of handheld devices such as mobile phones and PDA will also adopt 3D display technology. Recently, Samsung showed us a 3D OLED panel developed for mobile devices. Considering portability, the 3D screen of this mobile phone will not require people to wear special 3D glasses. In addition to Samsung, Dongzhi and other manufacturers have also introduced related technologies, the principle of which is achieved through a special "lens" covering the screen. It can "separate" the image displayed on the small display screen into two slightly different images and send them to the left and right eyes respectively, so that the images become stereoscopic and deep. Because the thickness of the "lens" is extremely thin, people can't even see its existence directly, which will not affect the normal display of the picture. 3D LCD is expected to occupy the high-end game market.

In addition to the 3D technology mentioned in this paper to realize stereoscopic images on ordinary 2D screens, a few years ago, foreign manufacturers introduced a spherical display device similar to a globe, which can really display stereoscopic 3D effects, and people can see different images from different angles. However, this display device is more used in medical or astronomical research and will not be sold as a consumer product.

With the development of technology, the distance between 3D display technology and ordinary consumers is getting closer and closer, and it is no longer the patent of industry users. After Samsung and Youpai both launched the game 3D display, people can move the 3D display into the bedroom instead of watching it in the cinema with others. With immersive stereoscopic images, 3D displays are very attractive to high-end gamers. In addition to individual users, 3D displays are also suitable for commercial and scientific research fields, such as displaying molecular structure models, military targets, cultural relics and artworks, exhibitions, corporate image display and other fields to play its unique role. I believe that with the further maturity of 3D technology, we will see 3D display devices in all fields of life in the future.
