[Abstract]:As an epoch-making technology, naked eye 3D display technology is an important research and application direction of next generation TV technology. High-definition naked eye 3D TV will lead the trend of the times into thousands of households. In this paper, the structure and function of 3D image processing system for high definition naked eye are analyzed, and the special drive IC for 3D image processing of high definition naked eye is developed. The data receiving in 3D image processing system of naked eye is studied and analyzed emphatically. Handling and transmission display problems. The main work of this paper is to develop a special drive circuit for 3D video signal processing in HD naked eye. According to the characteristics of high definition naked eye 3D TV transmission data and the need of real-time processing of image data transmission and display, The system frame based on FPGA core processing chip is built. The powerful parallel processing ability of FPGA can accomplish the task of receiving, transmitting and processing high speed and large amount of image signal data in the system with high speed and high quality. The hardware design requirements and transmission protocol of HDMI interface are analyzed and the image receiving circuit module based on HDMI decoding chip is designed. According to the requirement of display device interface, the 3D image transmission circuit module based on LVDS interface is designed. PCBs are designed according to the circuit schematic diagram. Finally, the algorithm of stereo image fusion and the logic design of timing control technology are finished. The system converts the received left and right format images into stereoscopic display format by separating interpolation and fusion. Two groups of fifo and four fifo are used to complete the data separation. After data separation, according to the timing requirements of the display equipment, it is sent to the sub-screen of the left and right eyes of the display device, and the image interpolation fusion in the left and right formats is completed. Realization of stereo image display. LVDS interface high-definition naked eye 3D image transmission module logic driver design .FPGA internal integration of the rich function of IP core module logic design using IP core Lvds_tx to achieve LVDS interface image data transmission. Through the deep research and analysis on the transmission of 3D TV image with high definition and naked eye, the LVDS interface high definition display is realized based on FPGA, which is a special drive IC for high definition 3D TV image processing. Left and right format stereo image separation fusion display and other functions. The system design scheme can provide the technical reference for the design and development of special customized drive chip for naked eye 3D TV, and promote the rapid development of naked eye 3D TV industry.
