Display Panel Support Layout for Higher 3D Sub-Pixel Aperture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-resolution 3D display technologies, the small sub-pixel pitch leads to difficulties in sub-pixel layout and a low sub-pixel aperture ratio, compromising compatibility with light field displays and overall display effectiveness.
Innovation Solution
The display panel incorporates an array substrate with scanning and data lines, sub-pixels arranged in rows, and supporting parts with orthographic projections between sub-pixel rows, optimizing the layout to enhance the aperture ratio and reduce the light shielding region.

Engineering Contradiction Analysis
1Manufacturing precision
If the sub-pixel pitch is reduced to achieve ultra-high resolution display, then the pixel density and viewing continuity are improved, but the sub-pixel aperture ratio decreases and layout becomes more difficult
Solution Approach 1:
The supporting part is divided into two sub-supporting parts: a first sub-supporting part extending in the first direction and a second sub-supporting part extending in the second direction. This segmentation allows the supporting structure to be distributed more efficiently, reducing the overall area occupied by supporting structures and thereby increasing the sub-pixel aperture ratio while maintaining structural support functionality.
Solution Approach 2:
The supporting part transitions from a single-dimensional structure to a two-dimensional cross-shaped structure by combining the first sub-supporting part (extending in the first direction) and the second sub-supporting part (extending in the second direction). This dimensional change allows the supporting part to provide structural support in multiple directions while minimizing the area it occupies, thus improving the aperture ratio.
2Manufacturing precision
If the sub-pixel pitch is reduced to achieve ultra-high resolution display, then the pixel density and viewing continuity are improved, but the layout complexity increases
Solution Approach 1:
The supporting part is segmented into two perpendicular sub-supporting parts, which simplifies the layout process by allowing each sub-supporting part to be aligned with the scanning and data lines respectively. This segmentation reduces layout complexity while maintaining the structural integrity needed for high-resolution displays.
Solution Approach 2:
The first sub-supporting part and the second sub-supporting part have different orientations (one extends in the first direction, the other in the second direction), creating an asymmetric cross-shaped structure. This asymmetric design optimizes the layout by aligning with the orthogonal arrangement of scanning and data lines, reducing layout complexity while supporting ultra-high resolution requirements.
3Area of moving object
If the supporting part area is reduced to increase aperture ratio, then the light-transmitting area is improved, but the structural support strength may be compromised
Solution Approach 1:
The supporting part adopts a two-dimensional cross-shaped structure with sub-supporting parts extending in perpendicular directions. This dimensional change allows the supporting structure to provide strength in multiple directions simultaneously while occupying minimal area, thus maintaining structural support strength while maximizing the aperture ratio.
Solution Approach 2:
The supporting structure is segmented into multiple sub-supporting parts distributed in different directions. This segmentation distributes the mechanical load across multiple orientations, maintaining structural support strength while reducing the total area occupied by supporting structures, thereby increasing the aperture ratio.
