Design of a Data Sample and Storage System for Glasses-free Displays Based on FPGA

摘要

In order to realize the data from VGA output to show on the 4.8" color TFT-LCD developed by CPTF, we design a data sample and storage system from VGA output to LVDS port. The system uses two SDRAM to realize ping-pang store, and finishes the main logic control in FPGA. Using the AD9883A can realize 3 channels, 8 precision data acquisition, the acquired data, which is stored in the SDRAM, is changed into LVDS signals by the LVDS transmitter, at the last display in the screen. The design of hardware and software is reasonable and feasible. As long as each eye is 60Hz, the panel can get good 3D results.
