The invention discloses a base plate detection device, base plate detection method and base plate detection module and belongs to the technical field of base plate detection. The base plate detection device comprises at least two detection modules. Each detection module comprises a height measurement sensor detecting the height of a convex defect on a to-be-detected base plate and a sensor support fixedly connected with the height measurement sensor, wherein the sensor support can support the height-measurement sensor; the at least two detection modules employs either a linear contact type height measurement method or a point contact type height measurement method to measure the height of the convex defect on the to-be-detected base plate; and each detection module is corresponding to one height measurement method. By the use of the base plate detection device, a problem of low accuracy of convex defect height measurement by the base plate measurement device in the prior art can be solved; and accuracy of convex defect height measurement can be improved. The base plate detection device is applied to base plate detection.
Description
technical field [0001] The invention relates to the technical field of substrate detection, in particular to a substrate detection device, a substrate detection method and a substrate detection module. Background technique [0002] The display device usually includes an array substrate and a color filter substrate formed in a box, and a liquid crystal layer filled between the array substrate and the color filter substrate. The liquid crystal layer includes liquid crystal molecules and spacers (English: PostSpacer, referred to as: PS), PS Located on the color filter substrate and in contact with the array substrate, it is used to support the array substrate and the color filter substrate, so that a cavity is formed between the array substrate and the color filter substrate, and the liquid crystal molecules are located in the cavity, wherein the color filter substrate includes the color filter substrate. The film layer, the pixels on the color film layer can filter the light, ...
