Implement Of Interface And Image Manipulation Circuits For Title Screen PDP

Title screen plasma display panel is regarded as a promising large screen display in this century. It has advantages of high image quality, wide visual angle, thinness, flatness and edgeless. There would be great realistic significance on developing TSPDP technologies in our country.Interface circuit and image manipulation circuit play important roles in TSPDP system. There performance would directly decide the qualities of TSPDP. Doing research on these areas is very necessary.This paper implements DVI interface circuit and image manipulation circuit for TSPDP. Both circuits are based on FPGA. The circuits can receive DVI signals from computer and perform image partition according to the structure of TSPDP, color display is also controlled. These circuits utilized Verilog HDL to design FPGA. The whole circuit system is tested on TSPDP designed by Zhejiang University and has great performance. Finally, some skills and methods for circuit design and adjustment are summarized.
