Problems solved by technology

In this way, when a new Micro LED or Mini LED is introduced at the position of the candidate binding corresponding to some normal light-emitting elements, both the light-emitting elements that were originally normally illuminated and the new light-emitting elements will emit light, and the luminous brightness of this part of the area is relatively large. There will be uneven brightness and darkness on the display panel, which will affect the normal display effect

Abstract

The invention discloses a display panel, a repairing method thereof and a display device, the display panel comprises a substrate, a main conductive pad unit and a standby conductive pad unit, the main conductive pad unit and the standby conductive pad unit are located on one side of the substrate, and the display panel comprises a plurality of first pixel areas and a plurality of second pixel areas; the display panel further comprises a plurality of light-emitting elements, the light-emitting elements comprise a first type of light-emitting elements and a second type of light-emitting elements, and in the first pixel area, the main conductive pad unit is connected with the first type of light-emitting elements; in the second pixel area, the main conductive pad unit is connected with the first type of light-emitting elements, and at least part of the standby conductive pad units are connected with the second type of light-emitting elements; in the display stage, in the second pixel area, only one of the first type of light-emitting elements and the second type of light-emitting elements emits light. Thus, the phenomenon that the local brightness is too high due to the fact that the first light-emitting element and the second light-emitting element emit light at the same time is avoided, and the overall display brightness uniformity of a product is improved while the first type of light-emitting elements which do not emit light are repaired.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a repair method thereof, and a display device. Background technique [0002] From the era of CRT (Cathode Ray Tube, cathode ray tube) to the era of liquid crystal, and now to the era of OLED (Organic Light-Emitting Diode, organic light-emitting diode), the display industry has experienced decades of development and has become ever-changing. The display industry is already closely related to our lives. From traditional mobile phones, tablets, TVs and PCs to current electronic devices such as smart wearable devices and VR, display technology is inseparable. [0003] Existing light-emitting components (such as Micro LED or Mini LED products) in the mass transfer process, after completing the binding of Micro LED or Mini LED to the substrate, if it is detected that some Micro LED or Mini LED do not emit light, they often cannot be placed on the subs...
