| Abstract: | In this paper,a method of designing a colored touching screen controller with FPGA is presented. A TFT-LCD controller and an interface controller of ADS7843 chip are designed in FPGA according to interface rules. The touch-enabled function on the TFT-LCD is realized in FPGA. This colored touching screen controller has a positive display effect and fast response speed. And it can be used for the design of IP core of colored touching screen. |
