Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current organic self-luminous display panels face challenges in enhancing display effects due to limitations in sub-pixel arrangement and light emission efficiency.
Innovation Solution
The display panel design includes specific sub-pixel configurations where first and second sub-pixels form virtual quadrilaterals with third sub-pixels inside, and circumscribed virtual parallelograms are used to optimize sub-pixel placement and light emission, ensuring improved light distribution and reduced leakage current.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional sub-pixel arrangement is used, then manufacturing is simple, but display effect and light emission efficiency are insufficient
Solution Approach 1:
The sub-pixel is divided into multiple light emitting regions with different emission characteristics (first light emitting region with first wavelength, second light emitting region with second wavelength). This segmentation allows each region to be optimized for specific light emission efficiency while maintaining overall sub-pixel functionality, directly addressing the contradiction between simple arrangement and high light emission efficiency.
Solution Approach 2:
Different portions of the sub-pixel are assigned different light emitting properties - the first light emitting region emits at a first wavelength while the second light emitting region emits at a second wavelength. This local differentiation optimizes light emission efficiency in specific areas without requiring complete redesign of the entire display structure.
2Manufacturing precision
If sub-pixel density is increased to improve resolution, then display quality improves, but leakage current increases
Solution Approach 1:
A pixel electrode structure is introduced as an intermediary element that selectively connects to different light emitting regions. The pixel electrode configuration allows precise control of electrical connections, enabling high-resolution displays while minimizing leakage current by establishing controlled conduction paths only where needed.
Solution Approach 2:
The electrical connection structure is designed to dynamically control current flow paths based on the specific sub-pixel configuration. By making the connection structure adaptable to different sub-pixel arrangements and densities, the system can achieve high resolution while maintaining low leakage current through optimized electrical pathways.
3Illumination intensity
If opening ratio is increased to improve brightness, then light emission improves, but control precision over light distribution decreases
Solution Approach 1:
The light emitting area is segmented into multiple controlled regions (first and second light emitting regions with different wavelengths). This segmentation enables precise control over light distribution while maintaining high overall opening ratio, as each segment can be independently optimized for both brightness contribution and spatial control.
Solution Approach 2:
Different wavelengths of light are emitted from different regions within the sub-pixel. By changing the wavelength parameter across different light emitting regions, the system achieves both high brightness (through increased opening ratio) and precise light distribution control (through wavelength-specific optimization of each region).

AI summary
Provided are a display panel and a display device. The display panel includes a first sub-pixel, a second sub-pixel and a third sub-pixel. Two first sub-pixels and two second sub-pixels form a first virtual quadrilateral. Four third sub-pixels form a second virtual quadrilateral, and the first sub-pixel or the second sub-pixel is located within the second virtual quadrilateral. Each of the first sub-pixel and the second sub-pixel includes a third side, the third side includes a first sub-segment and a second sub-segment. Each of the first sub-pixel and the second sub-pixel include a corresponding circumscribed virtual parallelogram, and a line connecting a center of the circumscribed virtual parallelogram corresponding to the first sub-pixel and a center of the circumscribed virtual parallelogram corresponding to the second sub-pixel at least intersects with a third side of one of the first sub-pixel or the second sub-pixel.
