【摘要】 设计了一种用于平板显示器测量和评估的图像信号发生器.它可以根据液晶显示器和等离子体显示器测量的不同需要产生稳定、可靠、灵活的图像信号,并满足多种显示模式的要求.整个系统以LabVIEW软件作为控制平台,PC通过I2C总线将控制信号发送到以FPGA作为主控的图像产生处理板(Image Board),由其产生相应的图像信号并输入待测显示器.图像板还可以将DVI信号转换为LVDS信号,以便直接对显示器面板进行测试.更多还原

【Abstract】 A video pattern generator is developed to generate stable,dependable and flexible pattern signals for FPD measurement and evaluation.This video generator is suitable for various display modes and meets different measurement requirements of LCD and PDP.The total system is controlled by LabVIEW software.The PC sends control signal via I2C bus to the image generation and process board(Image Board) mainly based on FPGA.Image Board generates pattern signal and transmits it to the display under test.Image Board can also convert DVI signal to LVDS signal for the display panel measurement.更多还原
