Description: This study discusses the Linux based on S3C2410 LCD controller driver design and implementation, this paper introduces the data and control pin S3C2410 LCD controller, and gives the control process and LCD LCD controller set rules, the reference to TFT - LCD LQ092Y3DG01 logic required to design the drive circuit and timing requirements, set up the main LCD register; This paper discusses the implementation method of LCD driver based on FrameBuffer mechanism in embedded Linux. Linux frame buffer device drivers framework presented in this paper, detailed analysis of the frame buffer device driver hierarchy, the core function module and data structure, design the FrameBuffer processing mechanism and the underlying driver interface function for LCD panel how to write in the embedded Linux frame buffer device driver. Finally, on the basis of the FrameBuffer mechanism, based on the development platform of samsung S3C2410 processor systematically developed the LCD display driver under embedded Linux, implements a simple embedded GUI API design, graphics and shows clear on LQ092Y3DG01 stable images and characters. The test indicates that the driver is versatile and can drive most LCD. It is very portable and can be used in other embedded systems after a few modifications. It is a better solution for S3C2410 drive LCD
