【正文】 s health. Especially as the emergence of TFTLCD electronic books, human beings will e into an era that with paperless office and no paper printing, and it will also cause human to learning, disseminating and recording the civilization way (3)Wide application scope It can be used normally in the temperature ranging from 20℃ below zero to 50 ℃ , and TFTLCD, that had been reinforced by temperature, its lowtemperature working temperature can achieve 80 ℃ below zero. TFTLCD can be either as mobile terminal display, or desktop terminal display, or can be big screen TV, is a full size video display terminal with fine performance. (4)High degree of automation of manufacturing technology. Largescale industrialization has the feature of good poducing characteristic. TFTLCD industry is now technologically mature, and mass production yield up to 90%. （ 5） TFTLCD easy integration and renewal TFTLCD is the perfect bination of largescale semiconductor integrated circuit technology and light source technology , it has a great potential to develop. Currently there are amorphous silicon, polycrystal silicon, and TFTLCD silicon, and there will be more TFT in other material,such as the glass substrates and plastic substrates. The design in this article has realized S3C2440 processor as hardware, with for portable embedded Linux system write tftlcd screen system driver technology. And this driver is based on Linux frame buffering system, which realizes S3C2440 LCD controller that in the bottom of driven and also provides apis interfaces of application system call for the upper. In writing good drivers will be written in the kernel, will pile good kernel burn wrote on development board. Establish LINUX system development environment, write a test program, crosspilation move developing board running after, detection driver. 。 Its display quality ranges from the most simple monochromatic character graphics to various specifi
