| Abstract: | Timing and logic requirement of a typical TFT LCD are introduced. Hardware circuits between embedded microprocessor S3C2440A and TFT LCD module with touch panel are designed. Based on embedded Linux system, driving program is developed to set parameters of RGB interface, adjust display quality and position, drive and control touch panel. The experiment results indicate that this set of devices can be universally used because it can driver different size TFT LCD with touch panel. This design can be well transplanted and it can provide a driving method for various embedded system that TFT LCD with RGB interface are used. |
