【文章內(nèi)容簡介】 ne which is necessary for reproducing manufacturing circuit, and also through the processing of membrane to manufacture mass semiconductor integrated circuit. Single crystal substrate can lower greatly the cost, and it is the outspread of the traditional large scale integrated circuit to large area, multifunction, low cost. It is more difficult to manufacture TFT that control LC or OLED switch performance on large glass or plastic substrates than manufacture largescale IC technology on silicon. Single crystal substrate is the top technology of modern production, its requirements for production environment( purification degrees is 100 levels), for purity of raw materials(purity of electronic special gas is %), and for production equipment and production technology are more strict than semiconductor largescale integrated. Its main characteristics are： （ 1） large area （ 2） High level of integration （ 3） Powerful （ 4） Lowcost （ 5） Process flexible （ 6） Extensive applying field Tftlcd screen principle of work: Tftlcd will bitmap pixel divided into red, green and blue three subpixel, and in its corresponding position within the device set R, G, surface of three miniature filter color film B, when LCD display device only as a light valve, control each subpixel light valve, filter can be used to control the color film。 hige through light Control of gray level light valve to control the corresponding filter through light color film how much。 Using R, G, B this three subpixel through different amount of light, can add color realize mixed color. Extremely rich If R, G, B this three subpixel all can realize to gray eye distinguishing ability 256 level gray drive, can realize 256x256x256 about 16 million color true color. The main characteristic of tftlcd in each pixel is configuring a semiconductor switching devices, since each pixel can directly control through the point pulse, make each node is a relatively ind
