Fpga-based Liquid Crystal Display Related Technology Research

With the continuous development of video technology and computer application technology, digital image display technology in the field of electronic communications and information processing has been widely used. Thesis research and implementation of FPGA-based processing of related technologies liquid crystal display, and topic has the great significance.Thesis, according to application needs, designed a collection can be adaptive to different resolution and refresh rate under the four image signals of image fusion system, enabling the display of multiple video signals. The image fusion system include acquisition module, scaling module, integration module, memory chip control module and the MCU interface module; paper FPGA-based design method given in detail acquisition module and the MCU interface module design, and implemented to the core of the AD9888 AT91FR40162 adaptive module and FPGA and the interface module; Reference ping-pong algorithm, the paper also studied and designed based on the dual-buffer arbitration. Paper gives examples of the experimental design, experimental testing and analysis show that the given scheme is feasible, a reference value of the related research.Image fusion system selected Virtex-IV FPGA core devices, combined with the AT91FR40162S, XCF32P VO48, and other chips. Video capture module, MCU interface module and the double buffer arbitration module in this system achieve the desired and satisfactory results.
