The invention discloses a device for detecting diffusion of liquid crystals. The device for detecting diffusion of the liquid crystals comprises an image acquiring unit and an image processing unit, wherein the image acquiring unit is arranged in an image acquiring area on a liquid crystal display panel, and is used for acquiring an image of the liquid crystal display panel; the image processing unit analyzes the acquired image to determine the area of an abnormal area of the image; the abnormal area of the image represents the area, where the liquid crystals are not diffused, on the liquid crystal display panel. The device for detecting diffusion of the liquid crystals is used for detecting defects, related to diffusion of the liquid crystals, on the liquid crystal display panel after frame sealing adhesive is cured, and detected results are fed back and used for adjusting parameters of injection and diffusion of the liquid crystals to eliminate the defects. The invention also discloses liquid crystal display panel manufacturing equipment including the device for detecting diffusion of the liquid crystals, and a method for detecting diffusion of the liquid crystals.
Description
technical field [0001] The invention relates to the field of display technology, and in particular to a liquid crystal diffusion detection device and method and a liquid crystal panel manufacturing device. Background technique [0002] At present, liquid crystal display has become the leading product in the current display market. The main structure of a liquid crystal display is a liquid crystal panel, which includes an array substrate, a color filter substrate, a liquid crystal layer, and the like. In the box-fitting process of the liquid crystal panel, a sealant is coated around the display area of the array substrate, liquid crystal is injected into the space enclosed by the sealant, and the color filter substrate and the array substrate are boxed together. Then the sealant is cured to form a liquid crystal panel (also called a liquid crystal cell). [0003] In the box-to-box process, the liquid crystal will not diffuse to the edge of the space enclosed by the sealan...
