Replace OLED of COG LCD for Watch-0.96 inch

The characteristics of TFT Liquid Crystal Display mainly have the characteristics of large area, high integration, strong function, low cost, flexible technology, and wide application fields.

Below we will introduce the various characteristics of TFT LCD Screen in detail:

(1) Large area: The first generation of large-area glass substrate (300mmx400mm) TFT screen production line was produced in the early 1990s. By the first half of 2000, the area of the glass substrate was expanded to 680mmx880mm. Recently, the glass substrate of 950mmx1200mm has also been put into operation Thin Film Transistor.

(2) High integration: The 1.3-inch TFT Display Chip used for liquid crystal projection has a resolution of XGA and contains millions of pixels. The film thickness of the 16.1-inch TFT liquid crystal display array with SXGA (1280x1024) resolution and amorphous silicon is only 50 nanometers. The integration level of TABONGLAS and SYSTEMONGLASS technologies, the requirements of equipment and supply technology, and the technical difficulty exceed those of traditional LSI Tft Lcd Module.

(3) Powerful function: The TFT LCD screen was originally used as a matrix addressing circuit to improve the characteristics of the liquid crystal light valve. For high-resolution displays, the correct control of the object element is achieved through the voltage adjustment in the range of 0-6V (the typical value is 0.2~4V), and the LCD screen can achieve high-quality high-resolution display TFT LCD Display.

(4) Low cost: Glass substrates and plastic substrates fundamentally solve the cost problem of large-scale semiconductor integrated circuits, opening up a broad application space for the application of large-scale semiconductor integrated circuits.

(5) Process flexibility: In addition to sputtering, CVD (chemical vapor deposition) MCVD (molecular chemical vapor deposition) and other traditional processes for film formation, laser annealing technology can also use amorphous film, multi-product film and single-product film. It can be used as silicon film, as well as other I-VI group and four-V group semiconductor film.

(6) Wide application fields. LCD liquid crystal display based on TFT technology is the pillar industry of the information society, and can also be applied to the rapidly developing thin film transistor organic electroluminescence (TFT-OLED) flat panel display.
