A kind of laser repair method of OLED screen body with follow-up lighting mechanism

Abstract

The invention discloses a laser repairing method for an OLED screen body with a follow-up lighting mechanism, which belongs to the field of OLED flexible display screen production. According to a laser repair method for an OLED screen body with a follow-up lighting mechanism of the present invention, in the repair stage, after the OLED screen body is lit by the electric contacts, the mobile carrier carrying the OLED screen body and the electric The lighting mechanism of the contact moves synchronously in the first direction, so that the point to be repaired of the OLED screen body is aligned with the laser unit in the first direction, and then the laser unit completes the repair of the OLED screen body. The repair method of the present invention completely avoids the vibration or jitter of the laser unit during the movement of the gantry by using the movement of the moving stage and the lighting mechanism. The OLED screen shakes or vibrates, so the repair method of the present invention improves the alignment accuracy of the OLED screen body and the laser unit, thereby improving the repair effect of the OLED screen body and improving the yield rate of the OLED screen body after repair.

Description

technical field [0001] The invention relates to the technical field of processing methods for OLED flexible display screens, and more particularly, to a laser repairing method for an OLED screen body with a follow-up lighting mechanism. 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, multiple inspection processes need to be performed, 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 inspection processes are dist...

Problems solved by technology

[0005] However, the weight of the laser repair device is relatively high, and the center of gravity is relatively high. Therefore, when the laser repair device moves to the defect position, the detection mechanism on it is prone to relatively large vibrations or shakes, so it is difficult to align At the same time, after the laser repair device stops moving, it will continue to vibrate under the action of its own inertia, thereby reducing the repair effect of the laser mechanism of the laser repair device on the screen body, and reducing the screen after repair. body yield
