Development Of A PCI Driving Card For Three-dimensional Display

In recent years stereo display technology has experienced a developing stage of accelerated popularization, the current 3D display technology is generally based on the principles of the parallax around eyes which need to simultaneously show two images, accordingly higher requirements are needed for the images circuit display. This paper makes a preliminary study on the driver circuit of the three-dimensional display.The PCI interface circuit has been designed with the chip PCI9054 to access high-speed data from computer in this paper. The logic control module chooses cyclone EP1C6Q240C8 as the logic control chip, producing VGA signal with row and column synchronization, and the system chooses 10bit D/A converter ADV7123 for analog signals, the data received from SDRAM will enter three latches and then flush into the D/A conversion chip ADV7123, finally the image can be displayed through the VGA interface and the design of software are simulated under the environment of quartus II.The 3d display driver circuit design in this paper is designed with plug and play features, independent of processors, strong compatibility; basically meets the need of three-dimensional display.
