Display Panel Subpixel Structure With Shared Non-Light-Transmitting Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels have a low aperture ratio due to the presence of support pillars and control transistors that occupy the light-transmitting area in sub-pixels, reducing their effectiveness.
Innovation Solution
The display panel design includes a first and second sub-pixel with transistors in a non-light-transmitting area and spacer structures in the same area, integrating two non-light-transmitting areas into one to increase the light-transmitting area, thereby enhancing the pixel aperture ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If support pillars and control transistors are provided in each sub-pixel, then the sub-pixel structure is stable and functional, but the aperture ratio of the sub-pixel is reduced
Solution Approach 1:
The patent merges the non-light-transmitting areas of two adjacent sub-pixels into a shared region. The first sub-pixel's transistor and the second sub-pixel's transistor are both disposed in the first non-light-transmitting area, which is shared between the two sub-pixels. This consolidation reduces the total non-light-transmitting area per sub-pixel, thereby increasing the aperture ratio while maintaining structural stability and functionality.
2Area of stationary object
If transistors are disposed in the light-transmitting area, then the aperture ratio increases, but the transistor function is compromised
Solution Approach 1:
The patent combines the transistor placement strategy by locating both transistors in a shared non-light-transmitting area. The first transistor is disposed in the first non-light-transmitting area, and the second transistor is also disposed in the same first non-light-transmitting area. This shared arrangement ensures both transistors have adequate space for functionality while maximizing the light-transmitting area of both sub-pixels.
3Manufacturing precision
If spacer structures are added to maintain cell spacing, then the cell gap is controlled, but the non-light-transmitting area increases
Solution Approach 1:
The patent integrates the spacer structures into the shared non-light-transmitting area. The spacer structures are disposed in the first non-light-transmitting area, which is already designated as a non-light-transmitting region. By placing spacers in this shared area rather than in each sub-pixel's individual non-light-transmitting area, the patent maintains precise cell spacing control while minimizing the total non-light-transmitting area and maximizing the aperture ratio.

AI summary
A display panel and a display device are provided. The display panel includes a plurality of repeating units arranged along a first direction and a second direction and a plurality of spacer structures corresponding to the repeating units. Each of the repeating units includes a first sub-pixel and a second sub-pixel disposed adjacently. A first transistor is disposed in a first non-light-transmitting area of the first sub-pixel, the second sub-pixel includes a second transistor disposed in the first non-light-transmitting area, and the spacer structure is only disposed in the first non-light-transmitting area.
