3.2 inch TFT LCD Module

TFT VS. LCD
In the fierce competition among many flat panel displays(FPD), why can TFT display stand out and become a new generation of mainstream displays? This is by no means an accidental, but owing to the inevitable development of human technology and thinking mode.
The liquid crystal has avoided the difficult light-emitting problem, and the light-emitting display device is broken down into two parts by using the excellent characteristics of the liquid crystal as a light valve, namely the light source and the control of the light source.
As a light source, brilliant results have been achieved in terms of luminous efficiency, full color, and service life, and they are still being deepened.
Since the invention of LCD, the backlight has been continuously improved, from monochrome to color, from thick to thin, from side fluorescent lamp type to flat fluorescent lamp type. The latest achievements in luminous light sources will provide new backlight sources for LCDs. With the advancement of light source technology, newer and better light sources will appear and be applied to LCDs.
The rest is the control of the light source. The technology and process of semiconductor large-scale integrated circuits are transplanted to develop the thin film transistor (TFT) production process, which realizes the matrix addressing control of the liquid crystal light valve and the cooperation of the light valve and the controller of the liquid crystal display, realizing the advantages of the liquid crystal display.
