摘要
五维运动台是检测平板显示器亮度、色度、均匀性及视角等性能指标的重要仪器设备,针对目前该类产品国产产品控制精度低、故障率高、功能不全,而进口产品价格昂贵的情况,采用了测量点偏移量补偿、PC机与多单片机通信、单片机定时器可逆计数、动态链接库等软硬件技术对原有国产五维运动台进行改进。改进后的五维运动台运行稳定可靠,测量精度高,完全可以满足平板显示器的检测要求。
Five-axis positioner is an important instrument for measuring the luminance, chromaticity, uniformity and view angle of flat panel displays. Due to the drawbacks of low control precision, high failure rate, incomplete function and high price, some advanced techniques, such as shift compensation of measuring spots, PC and multi-MCUs communication, MCU reversible counter and dynamic linkage library, are adopted to improve the performance of the positioner. The application shows that this positioner runs stably and accurately, and completely meets the testing requirements of flat panel displays.
