The work principle

hardware configuration and software design of the embedded system TFT-LCD are given.TFT-LCD regards as the display device of the embedded system

its device drivers must be implemented as Linux frame buffer device drivers in addition to those low level operations which only deal with commands provided by LCD controllers.In order to display the graphic which is in the graphic mode of the application software

programmer can get the data from the frame buffer device by receiving.By the design of the software and hardware in embedded system

it can arrive that TFT-LCD can be run normally.Detailed design may supervise explordering and transplant which used in embedded system in future.
