Advertising signs can be roughly divided into the following eight types: neon signs (retired), inkjet signs, exposed luminous characters, acrylic luminous characters, resin luminous characters, mini luminous characters, display signs and led color screen signs popular in recent years.

Neon signs have been retired for many years, and now 99% signs on the market are illuminated by led light sources.

Ink-jet signboard has a long history, and it has been used ever since because of its low price, simple production and construction and excellent advertising effect. However, with the improvement of people's quality of life, the aesthetic concept is also constantly improving, and it is difficult to leave a relatively new impression only by painting the signboard, especially in the production of the signboard at the door, the use of painting the signboard is not obvious.

With the appearance of led light source, the luminous characters with led as the luminous core have developed rapidly. Until today, the types of led luminous characters are no longer monotonous. In addition to the common acrylic luminous characters, exposure light characters, led light boxes, there are many, such as resin word, acrylic mini Seiko characters, etc., which can be described as varied.

Led color screen signboard, led color screen signboard can display pictures, characters and videos like led display screen, but the difference is that the pixel of led color screen is relatively low, but the cost performance is very high. The surface of color screen can be installed with luminous characters, which is a tall and elegant advertising signboard during the day and a dazzling first display screen at night. The price per square meter is only 10%~30% of the led display. Moreover, the bigger the colorful screen, the higher the installation height and the cheaper the unit price. When the sight distance and area exceed a certain range, the display effect can be completely comparable to that of the display screen.
