Among them, optical basic characteristics usually include brightness, contrast, uniformity, gamut, crosstalk, fHcker, and response time. Taking the brightness as an example, the Westerners have a higher acceptance of the color light than the Orientals on 5 200824428 IPD060592TW 22407twf.doc/006, so the two see the same Blu-ray day $, the Westerner feels that /3⁄4 degrees is In order to solve the above-mentioned problem of manual detection, another mother board is connected to the liquid crystal display panel, and the test item is sent through the control terminal, and the signal mother board is used to output a plurality of different test item signals to In the liquid crystal display panel, the screen displayed by the liquid crystal display panel is subsequently detected. Since the motherboard is limited by the corresponding parameter adjustment between the hardware and the software, the grounding f influences the optical characteristics, resulting in distortion of the optical characteristics. It can fully comply with the requirements of human-detected liquid crystal display panels. In addition to the above-mentioned signal mother board, there is also a color characteristic for detecting the display. Optical analyzers. Optical analyzers can provide a variety of detection items.
