Description

technical field [0001] The invention relates to a display detection device, in particular to a liquid crystal display high and low temperature and light automatic detection device. Background technique [0002] Whether it is production or life, the use of liquid crystal displays is becoming more and more widespread, and there are many types of liquid crystal displays, but no matter what kind of liquid crystal display, it faces a problem, the visibility when used in a light environment. At present, most of the detection of liquid crystal displays in the lighting environment is carried out by using optical detection instruments under the illumination of fluorescent lamps. Due to manual detection, the detection range is limited, and only the reflection and diffuse reflection of several fixed angles can be detected, and When detecting different angles, it is necessary to replace unused angle fixtures, the detection efficiency is poor, the detection range is small, and the detect...

Problems solved by technology

At present, most of the detection of liquid crystal displays in the lighting environment is carried out by using optical detection instruments under the illumination of fluorescent lamps. Due to manual detection, the detection range is limited, and only the reflection and diffuse reflection of several fixed angles can be detected, and When detecting different angles, it is necessary to replace unused angle fixtures, the detection efficiency is poor, the detection range is small, and the detection accuracy is poor

[0003] Liquid crystal displays are also used in high-temperature or low-temperature environments, so it is also necessary to perform optical performance testing in high-temperature or low-temperature environments, and high temperature or low temperature will cause greater damage to optical detection instruments, resulting in shortened service life, and Will affect the detection accuracy
