提出将不同的仪器组合达到实时量测液晶显示器辉度及响应时间特性,即利用搭配视效响应滤光片的光探测器检测液晶显示器响应时间,光辉度计量测液晶显示器辉度及色度,此搭配滤光片的探测器有直径10mm的大感光面积。设计了一种由光纤及准直透镜至光探测器的光学系统,此系统具有较小收光探头体积、调整光点大小及容易对位的优势。采用不同光纤及准直透镜设计收光光点大小,对于检测辉度较小液晶显示器,可选用较大的准直透镜。对于较高空间分辨率或较小待测物,可利用搭配不同光纤及准直透镜达到小的收光光点。根据不同规格要求可设计光纤及光纤两边的准直透镜。分析了检测液晶显示器不同视角及对于此系统的校正方法。该系统将可实现液晶显示器实时多点检测,达到快速、高分辨率的优势。
It is proposed to measure the brightness and response time of liquid crystal display (LCD) by real-time measurement of different instrument combinations. That is, the photodetector with visual effect response filter is used to detect the response time of liquid crystal display. The brightness meter measures the brightness and chromaticity of liquid crystal display, This filter with a detector diameter of 10mm large area of ?? light. An optical system consisting of an optical fiber and a collimating lens to a photodetector is designed. The system has the advantages of smaller volume of the light-receiving probe, size of the spot and easy alignment. Different optical fibers and collimating lenses are designed to receive the light spot size. For the detection of small LCDs, a larger collimator lens may be used. For higher spatial resolution or smaller objects to be measured, different light sources and collimating lenses can be used to achieve a small spot size. According to the requirements of different specifications can be designed on both sides of fiber optic and optical collimator lens. Analyze the different perspectives of liquid crystal display (LCD) and the calibration method for this system. The system will be able to achieve real-time multi-point liquid crystal display detection, to achieve fast, high-resolution advantages.
