Abstract

The invention discloses a method for repairing defects of an OLED screen body, and belongs to the field of OLED flexible display screen production. The OLED screen defect repair method of the present invention uses at least two follower modules to alternately carry the OLED screen to carry out the defect repair process, and the defect repair process completes the transportation of the OLED screen through the preparation stage, and completes the connection between the mobile carrier and the lighting mechanism ; Complete the alignment and repair of OLED screen body defects through the repair stage; complete the homing of the mobile carrier and lighting mechanism through the end stage. Wherein, when one of the at least two servo modules performs the repair phase, the rest of the servo modules perform the preparation phase and / or the repair phase, thus effectively shortening the number of different servo modules alternately performing the OLED screen. The interval time of body defect repair can be improved, and the efficiency of OLED screen body defect repair can be improved.

Description

technical field [0001] The invention relates to the technical field of processing methods for OLED flexible display screens, and more particularly, to a method for repairing defects of OLED screen bodies. Background technique [0002] The biggest difference between an OLED flexible display and a liquid crystal display is that the OLED flexible display can be bent and deformed to achieve curved display. In addition, compared with liquid crystal displays, OLED flexible displays have lower energy consumption and longer service life, which is one of the mainstream directions of future display technology development. [0003] In the production process of OLED flexible display, defects such as bright spots are prone to occur, so it is necessary to perform multiple inspection processes, aiming to detect defective products as early as possible and avoid wasting costs. The inspection process generally includes substrate inspection, panel inspection, screen inspection, etc. These ins...
