ZYNQ-FPGA-LCD display color block

1. Related knowledge In TFT LCD, TFT refers to thin film transistor (Thin Film Transistor), and LCD refers to (Liquid Crystal) liquid crystal. There are three main parts of an LCD screen: resolution (pixels), pixel format (color format: RGB, YUV), and drive timing RGB format: R red, G green, B blue. 888 and 565 formats […]
