OGS, full name glass solution, single touch screen, multi-chip (such as G+ G, G+ F, etc. ), in contrast, the original touch screen needs multiple pieces (glass or diaphragm), OGS is made directly on the glass cover technology of touch sensor, which may be much thinner and cheaper than multiple pieces. OGS is used with battery (Samsung S series) and battery (-Apple iphone5).
Full fit is appropriate, also called surface fit, contrast fit (or plastic mouth in the frame), the front glue is generally word of mouth, and the display is a touch screen module. Only after 2 weeks and 4 weeks of bonding, the glue sticks together, so the brightness contrast is not completely matched, so it is suitable for technologies that have only been developed for two years (compared with OCA and OCR), and some of them are doing well at present.
Part of IPS LCD technology, but still TFT-LCD, which belongs to plane conversion technology (original vertical conversion). The relatively large screens are IPS LCD screen (currently the representative of Apple on mobile phones) and AMOLED screen (the representative of Samsung).
