Problems solved by technology
When alternate binding positions are introduced on the substrate, the alternate binding positions will increase the reflectivity of the substrate. Considering that Micro LED or Mini LED products usually do not introduce polarizers, polarizers cannot be used to reduce the reflectivity of the substrate
Therefore, how to reduce the introduction of candidate binding sites to increase the reflectivity of the substrate has become one of the technical problems to be solved urgently at this stage.

The invention discloses a substrate, a display panel and an assembly detection method of the display panel, and relates to the technical field of display. The substrate comprises a plurality of sub-pixel areas which are arranged in an array mode, wherein each sub-pixel area comprises a main conductive gasket unit and a standby conductive gasket unit which are arranged on the substrate, an anti-reflection layer is arranged on the side, which is close to the main conductive gasket unit and the standby conductive gasket unit, of the substrate, and the orthographic projection of the anti-reflection layer on the substrate at least covers the orthographic projection of the standby conductive gasket unit on the substrate. According to the invention, the anti-reflection layer is used for at leastcovering the standby conductive gasket unit, and the problem that the reflectivity of the substrate and the display panel is increased due to introduction of the standby conductive gasket unit is avoided, so that the reflectivity of the substrate and the display panel can be better reduced, and the display effect of the display panel is improved.
Description
technical field [0001] The present invention relates to the field of display technology, and more specifically, to a substrate, a display panel and an assembly inspection method thereof. Background technique [0002] In the mass transfer process of existing Micro LED or Mini LED products, 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, it often cannot be carried out at the original binding position. Instead of repairing, set a backup binding position at the normal binding position. If a Micro LED or Mini LED that cannot emit light is detected, just refill the Micro LED or Mini LED at the standby binding position. When alternate binding positions are introduced on the substrate, the alternate binding positions will increase the reflectivity of the substrate. Considering that Micro LED or Mini LED products usually do not introduce polarizers, polarizers cannot be used to reduce the ref...
