Abstract

The invention discloses a method for repairing an LED display screen. The method comprises the following steps of: removing packaging glue of the LED display screen to expose a light-emitting element; picking out abnormal light-emitting elements to expose bonding pads; and mounting normal light-emitting elements on the pads. By removing the packaging glue, picking and removing the abnormal light-emitting elements and installing the normal light-emitting elements, the abnormal LED display screen sealed with the glue can be repaired, the abnormal LED display screen can be reused, scrapping is avoided, and cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a method for repairing LED display screens. Background technique [0002] At present, after the surface sealing process of LED (Light Emitting Diode, light-emitting diode) display screens, due to long-term lighting aging or external force effects such as collisions, LED short circuit / open circuit and other reasons often cause poor display, including but not limited to Bright lines / dark lines / bright spots / dead lights / streak lights / monochromatic lights, etc., seriously affect the optical display effect and give consumers a very poor viewing experience. [0003] At present, the display screens with similar abnormalities after sealing cannot be repaired, and the abnormal display screens can only be replaced with new ones. The replaced abnormal display screens can only be scrapped, and the maintenance cost is high. [0004] Therefore, how to provide a method for repairing...
