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.

Abstract

The invention discloses a substrate, a display panel and an assembly detection method thereof, and relates to the field of display technology. The substrate includes a plurality of sub-pixel regions arranged in an array, and each sub-pixel region includes a main conductive pad unit and a backup pad unit arranged on the substrate. As for the conductive pad unit, the side of the substrate close to the main conductive pad unit and the spare conductive pad unit is provided with an anti-reflection layer, and the orthographic projection of the anti-reflection layer on the substrate at least covers the area of ​​the spare conductive pad unit on the substrate. orthographic projection. The present application utilizes the anti-reflection layer to at least cover the spare conductive pad unit, which avoids the problem of increased reflectivity of the substrate and display panel caused by the introduction of the spare conductive pad unit, thereby helping to reduce the reflectivity of the substrate and display panel and improve the display. The display effect of the panel.

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...
