3D Display Panel Anode Overlap to Eliminate Moiré Fringes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D display technologies suffer from moire fringes (mura) due to non-continuous light emission by sub-pixels, leading to bright and dark regions that impair the display effect.
Innovation Solution
A display panel design with alternating first and second sub-sub-pixel structures, where anodes are connected or overlap orthographically, and partitioned by T-shaped structures, eliminating gaps between sub-pixels to ensure continuous light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sub-pixels are arranged in conventional 3D display panels, then 3D display function is achieved, but dark regions and moire fringes appear due to non-continuous light emission
Solution Approach 1:
The sub-pixel structure is segmented into multiple sub-sub-pixels (first and second sub-sub-pixel structures) with alternating arrangements. Each sub-sub-pixel has its own anode structure, allowing independent light emission control to fill dark regions while maintaining 3D display functionality through selective driving of different sub-sub-pixel groups
Solution Approach 2:
The patent introduces a new spatial dimension by adding second anodes at the side of partition structures away from the back plate, creating overlapping orthographic projections. This dimensional addition ensures continuous light coverage in the observation region, eliminating dark regions and moire fringes while preserving 3D display capability
2Reliability
If partition structures are added to separate sub-pixels, then light emission control is improved, but device complexity increases
Solution Approach 1:
The partition structures serve multiple functions simultaneously: they physically separate adjacent first anodes, provide mounting surfaces for second anodes, and act as structural support elements. This multi-functionality reduces the need for additional separate components, managing device complexity while ensuring reliable light emission control and continuity
Solution Approach 2:
The patent merges the partitioning function with the light emission function by integrating second anodes directly onto the partition structures. This combination eliminates the need for separate partitioning and light emission components, reducing overall device complexity while maintaining reliable continuous light emission across the display panel

AI summary
A 3D display assembly, a display panel thereof and a method of manufacturing display panel. The display panel includes: a back plate, and a plurality of sub-pixel structures and partition structures on the back plate. In a first direction, each of the sub-pixel structures includes one or more first sub-sub-pixel structures and one or more second sub-sub-pixel structures arranged alternately. The first sub-sub-pixel structures have the same luminous color as the one or more second sub-sub-pixel structures. Each of the first sub-sub-pixel structures includes a first anode, and each of the second sub-sub-pixel structures includes a second anode. Second anodes are disposed at a side of the partition structures away from the back plate. Adjacent first anodes are partitioned by a partition structure. Orthographic projections of the first anodes on the back plate and orthographic projections of the second anodes on the back plate are connected, or the orthographic projections of the first anodes on the back plate and the orthographic projections of the second anodes on the back plate are overlapped and there is no non-light emitting region between sub-sub-pixel structures, therefore, no dark region is formed in a human eye observation region during 3D display, thereby solving moire problem.
