Description

Technical Field

[0001] This utility model relates to the field of OLED microdisplay technology, and in particular to a dual-anode structure for compensating pixels. Background Technology

[0002] OLED microdisplays have become a mainstream choice in consumer electronics due to their advantages such as high contrast, wide viewing angle, and wide color gamut. However, defects may occur during the fabrication process of the anode and organic layer, leading to short circuits or open circuits in the sub-pixels that constitute the three primary colors. This results in sub-pixel defects and the failure of one of the primary colors, affecting display quality and product yield. As OLED microdisplays continue to penetrate industries such as virtual reality and augmented reality, there is a need to further improve the performance of OLED microdisplays while reducing production costs. Utility Model Content

[0003] This invention provides a dual-anode structure for compensating pixels, which can improve the problem of dead pixels in OLED microdisplays.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dual-anode structure for compensating pixels includes a substrate, a T-shaped connecting wire, and dual-region anodes. The T-shaped connecting wire has a recess on the substrate layer, an anode contact at the recess, and a T-shaped connecting wire at the recess of the substrate. Dual-region anodes are respectively provided on both sides of the top of the T-shaped connecting wire.

[0006] Furthermore, an insulating layer is provided between the dual-region anodes on the same T-shaped connecting conductor; an insulating layer is provided between the dual-region anodes on adjacent T-shaped connecting conductors.

[0007] If a certain area has a leaking or defective anode, laser ablation can remove the corresponding anode on one side, while the other anode in the same area still provides power. This dual-anode structure compensates for sub-pixels, improving the defective pixel problem in OLED microdisplays and thus increasing yield. Attached Figure Description
