Abstract

The invention discloses an OLED (Organic Light Emitting Diode) panel display defect restoration method. The method comprises the following steps that when the OLED panel display defect restoration is required, firstly, an OLED panel is fixed on a vacuum absorption platform through vacuum; then, the OLED panel is lightened through a light-up system, at this moment, an approximate position of a repairable display defect can be determined by the lightened OLED panel, and the display defect is labeled; an adjustable platform of a display defect detection device is adjusted to move a microscope at a position above the display defect labeled in the previous step, the microscope is adjusted for accurately positioning the display defect, and image information of the display defect can be obtained through a display device; and a laser generator is opened, and under the real-time monitor and guidance of the display device, an emitted laser beam is utilized to display and accurately restore the defect.

Description

technical field [0001] The invention belongs to the technical field of OLED display, and particularly relates to a method for repairing display defects of an OLED panel. Background technique [0002] After the OLED panel completes the aging process, it is necessary to check and mark the display defects of the OLED panel, and repair the repairable display defects. At present, the commonly used inspection and repair methods are: first, manually hold the microscope to inspect the display defects; then, mark the display defects; third, transfer the marked substrate to the laser repair table to locate the display defects again; In four steps, laser repair is performed on the display defect part. Although this inspection and repair method is simple to operate and easy to use, it is widely used, but there are some obvious display defects at the same time. The accuracy of the OLED panel depends on artificial factors, which requires higher operators and artificially affects the pro...
