According to the requirements of the TFT color LCD display system
an overall soft-core design of the controller in the LCD display combined of system on a chip (SOC) and programmable system on chip (SOPC) technique is proposed to successfully develop the digital signal tester
which is based on an embedded Nios soft-core FPGA product. The programs to display points
maps and Chinese characters have a certain reference value to the designs of a variety of LCD instrumentation equipment.
