Abstract: It is disclosed an apparatus for detecting liquid crystal diffusion. The apparatus comprises an image acquisition device and an image processing device. The image acquisition device acquires an image of a liquid crystal panel in an image acquiring region. The image processing device analyzes the acquired image to determine an area of an image abnormal region, and the image abnormal region is a region of the liquid crystal panel to which liquid crystal has not diffused. After curing of a frame sealant, defects about liquid crystal diffusion in the liquid crystal panel are detected, and the detected results are feedback to adjust parameters for injecting and diffusing liquid crystal for eliminating these defects. It is further disclosed an apparatus for fabricating a liquid crystal panel and a method for detecting liquid crystal diffusion.
