Description

technical field [0001] The invention relates to the field of liquid crystal panel thickness measurement, in particular to a liquid crystal panel automatic thickness measurement device. Background technique [0002] The LCD panel can largely determine the brightness, contrast, color, viewing angle and other very important parameters of the LCD display. The development speed of LCD panels is very fast. From the third generation in the past few years, it has rapidly developed to the fourth and fifth generations, and then skipped the sixth generation to reach the seventh generation, and an updated eighth generation panel is also being planned. Manufacturers of LCD panels are mainly Samsung, LG-Philips, IVT, AUO, BOE, China Star Optoelectronics, etc. Due to the differences in the technical level of each company, the LCD panels produced are roughly divided into several different types. [0003] However, no matter what kind of LCD panel, it needs to be tested when it leaves the fa...

AI Technical Summary

Problems solved by technology

[0003] However, no matter what kind of LCD panel, it needs to be tested when it leaves the factory. The thickness of the transmitted LCD panel is measured manually with a micrometer. The measurement quality cannot be guaranteed, and the measurement points are limited, and the measurement time is long, which cannot truly reflect the LCD panel. All thickness data; and the consistency of different artificial measurement results for the same LCD panel is poor
