Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of achieving high pixel density and compatibility with light field display in 3D display technology is hindered by the difficulty in sub-pixel layout and low sub-pixel aperture ratio, which affects viewing continuity and display quality.
Innovation Solution
A display panel design with an array substrate and opposing substrate featuring supporting parts composed of first and second sub-supporting parts extending in different directions, optimizing the orthographic projection to minimize sliding and reduce light shielding, thereby increasing the light-transmitting area and aperture ratio of sub-pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the sub-pixel pitch is reduced to increase pixel density, then the viewing continuity and number of viewpoints improve, but the sub-pixel layout becomes more difficult and the aperture ratio decreases
Solution Approach 1:
The supporting part is divided into multiple sub-supporting parts (first sub-supporting part, second sub-supporting part, etc.) that extend in different directions. This segmentation allows each sub-supporting part to be independently optimized for its specific function, making the overall structure more manageable and easier to manufacture despite the high pixel density requirements.
Solution Approach 2:
Different sub-supporting parts are configured with different local characteristics - some extend in the first direction, others in the second direction, with varying lengths and positions. This local quality optimization allows the supporting structure to adapt to the specific geometric constraints of high-density pixel layouts while maintaining adequate aperture ratios.
2Manufacturing precision
If the sub-pixel pitch is reduced to increase pixel density, then the viewing continuity and number of viewpoints improve, but the aperture ratio decreases
Solution Approach 1:
The supporting structure utilizes two-dimensional spatial arrangement with sub-supporting parts extending in different directions (first direction and second direction). This multi-directional configuration optimizes the use of available space, allowing the supporting parts to provide adequate structural support while minimizing their footprint and maximizing the aperture ratio of sub-pixels.
Solution Approach 2:
By dividing the supporting part into multiple smaller sub-supporting parts distributed in different directions, the total supporting area is optimized to provide necessary structural function while minimizing the area occupied, thereby preserving larger aperture ratios for light transmission.
3Reliability
If traditional supporting part structures are used, then the substrate gap is maintained, but light shielding occurs and aperture ratio is reduced
Solution Approach 1:
The supporting part is segmented into multiple sub-supporting parts that are strategically positioned and oriented. This segmentation reduces the continuous light-blocking area while maintaining the gap-function at critical locations, allowing light to pass through other regions and improving the overall aperture ratio.
Solution Approach 2:
The supporting structure transitions from a conventional single-direction configuration to a multi-directional arrangement with sub-supporting parts extending in different directions. This dimensional optimization allows the supporting parts to maintain gap functionality while minimizing their projection area, thereby increasing the light-transmitting area.

AI summary
Provided in the embodiments of the present disclosure are a display panel and a display device. The display panel comprises: an array substrate, which comprises scan lines, data lines, and sub-pixels, wherein at least two sub-pixels adjacent to each other in a first direction and a second direction form a pixel island; an opposite substrate; a liquid crystal layer; and support parts, which comprise a plurality of first support parts and a plurality of second support parts. Each support part comprises a first sub-support part and a second sub-support part, wherein one of the first sub-support part and the second sub-support part is arranged on a surface of the side of the array substrate facing the opposite substrate, and the other one thereof is arranged on a surface of the side of the opposite substrate facing the array substrate. An orthographic projection of the first sub-support part divides an orthographic projection of the second sub-support part into a first part and a second part; and in each support portion, the length of the first part is not equal to the length of the second part.
