To understand the tft LCD two lamination technology, first of all, we need to understand the structure of tft display screen, which can be divided into three parts: the outer protective glass, capacitive-resistive touch screen and tft screen. When these three components are integrated, they need to be laminated. Generally need to be laminated twice, between the protective glass and touch screen only once, tft screen and touch screen need another time.

According to the lamination, can be divided into full lamination and frame paste two. tft screen using incomplete lamination technology, that is, framed. tft lcd of the following full lamination and frame paste two are introduced:

TFT Screen Frame Sticker

Framing is simply using double-sided adhesive to fix the touch screen on all four sides of the tft screen, the process is simple and low cost. But due to the tft screen and touch screen between the existence of air layer, light refraction after the display effect greatly reduced, become the biggest defect of the sticker frame. Some do not even need glue, just a snap to fix the three-layer structure together. When using these methods, tft screen will fall off once impacted, it is easy to enter the gray.

TFT Screen Full Lamination

With the development of technology and people's criticism of incomplete lamination technology, full lamination technology came into being. Compared with frame lamination, full lamination has many advantages. Full lamination technology can improve the gap between the layers of lamination, reduce the possibility of air and dust entering the tft screen and keep the tft screen clean. Full lamination technology eliminates the air between tft screens, which can greatly reduce light reflection and light transmission loss, thus increasing the brightness and enhancing the display effect of tft screens and making the screen more transparent. Full lamination screens are also thinner than traditional screens. The touch screen uses an optical adhesive to laminate the screen, adding only 25 microns to 50 microns to the thickness, which is 0.1 mm to 0.7 mm thinner than a normal laminated screen.

Overall, full lamination technology improves the gap between laminated layers, reduces the possibility of air and dust entering the tft screen, and keeps the tft screen clean. Full lamination works better and is more expensive than all others. If the product requirements are high, protective glass and touch screen can be full lamination, tft screen, touch screen can also be full lamination.
