Research On Naked-eyes3DTV Drive Technology Based On FPGA

With the popularity of digital TV and the state launch3DTV channels, the Naked-eye3D technology has been gradually used in LCD equipments. Comparing with the common TV, the Naked-eye3DTV can not only render the depth information of the image, but also make the viewer feel personally on the scene. The Naked-eye3DTV have board market prospect, it will become the mainstream of the next generation of television.The3D driver circuit research involves many parts like the hardware design and software development,etc. On the basis of study Naked-eye3D technology and LCD TV in and aboard, proposed the Naked-eye3DTV drive system design program according to the Naked-eye3D principle. The feasibility of using hardware to achieve the mapping between the three-dimensional image and the3D LCD is analyzed.Through selecting the main control chip and designing the peripheral circuit, the3D driver circuit schematic was designed and PCB was layout. After complete the system design, manual weld the multi-pin and high-density chip, test the3D driver circuit. Using the hardware description language to design the driver code and simulate and test the important code. The modularity program used in the philosophy of designing, Reading and decoding image files of SD card by programming the FPGA chip, then transporting the image date into SDRAM chip for processing. The image date is processed by FPGA chip, these data was sent to the VGA hardware encoding circuit to achieve the image display. The3D drive circuit work stable, image display effect is better. These researches provide a technical support for hardware image processing, laid the foundation for the ultimate realization3D LCD drive.
