FPGA Implementation for Image Processing Module in TCON
In order to satisfy the special demand for image display in TFT-LCD, this paper presents a synthesis design and its implementation for image processing in TCON of TFT-LCD. The modules, including contrast adjustment, luminance adjustment, Gama correction and dithering technique, are designed to deal with the zoomed image, and at the same time, match the real-time requirements. All the modules are successfully synthesized and simulated with EDA tools and then implemented in FPGA. The experimental results show that the designed TCON in FPGA with improved modules can substitute one in a commercial LCD, and obtain the video image with high speed and fine definition.
