Abstract: The disclosure discloses a quality inspection system for the entire process of inkjet printing manufacturing of display devices, which includes a substrate inspection module, a nozzle inspection module, an ink droplet inspection module, a coating thickness inspection module, and a control module. Through the design and matching of these modules, it is possible to realize a series of operations such as substrate inspection, nozzle inspection, flying ink droplet inspection, liquid coating inspection, and cured coating inspection. The system also discloses a corresponding quality inspection method for the entire inkjet printing manufacturing process for display devices. The system effectively compensates for the shortcomings of current technology which only inspect a single stage without taking the whole process into consideration, thereby realizing high-precision quality inspection of each stage in the inkjet printing manufacturing process of display devices, and significantly improving the quality and yield of the display device product.
