The invention provides a method, a module and a device for detecting a poor binding process in a display module manufacturing process. The method for detecting the poor binding process in the display module manufacturing process comprises the following steps: preparing an anisotropic conductive adhesive added with a piezo-chromic material; an anisotropic conductive adhesive added with a piezochromic material is adopted, and a panel is manufactured according to a binding process; obtaining the color development condition of each point position on the anisotropic conductive adhesive after the binding process; and according to the color development condition of each point position on the anisotropic conductive adhesive, obtaining the bad condition in the binding process. According to the method for detecting the poor binding process in the display module manufacturing process provided by the invention, the poor point location in the binding process is judged according to the color development condition of the anisotropic conductive adhesive after the binding process, so that the binding process function is normally realized; when the binding process circuit is not conducted, short circuit and other defects occur, rapid detection positioning and feedback equipment troubleshooting can be achieved, the defect analysis speed can be increased, the idle time of a production line can be shortened, and the operation efficiency can be improved.
Description
technical field [0001] The present application belongs to the technical field of display screens, and in particular relates to a method, a module and a device for detecting poor bonding process in a display module manufacturing process. Background technique [0002] Displays are widely used in various display scenarios in life due to their advantages of high penetration, high color gamut, and high contrast. The main production process of liquid crystal display (LCD) can be briefly described as the liquid crystal is dripped between the color filter (CF) and the glass substrate (TFT), and then the vacuum box is assembled, and the single box completed by the box is attached to the polarizer with the polarizer. After the module process such as flexible circuit board (PCB) binding is displayed, the final product is formed. Among them, the bonding process is the most important part of the entire module process. The main function is to connect the two ends of the chip on film (COF...
