Display Panel Sub-Pixel Segmentation for Transparency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transparency of display screens is compromised by inorganic and organic film layers used in pixel circuits, which affect the overall consistency and functionality, especially when cameras and other photosensitive devices are integrated.
Innovation Solution
A display panel design that divides sub-pixel regions into two areas, where the first region contains a buffer layer and pixel circuit layer, and the second region has a first electrode directly contacting the substrate without an inorganic film layer, reducing the coverage area of these film layers and enhancing transparency.

Engineering Contradiction Analysis
1Reliability
If inorganic film layers (buffer layer) are provided in sub-pixel regions, then pixel circuit functionality is ensured, but transparency of the display panel deteriorates
Solution Approach 1:
The sub-pixel region is divided into a first area (for pixel circuit) and a second area (for light emission). The buffer layer is selectively provided only in the first area, not in the second area. This segmentation allows the buffer layer to ensure pixel circuit functionality where needed while avoiding its negative impact on transparency in the light emission area.
Solution Approach 2:
The buffer layer is selectively formed only in the first area of the sub-pixel region where pixel circuit functionality is required, rather than uniformly across the entire sub-pixel region. This local quality approach ensures that the buffer layer provides its protective and functional benefits where needed while maintaining high transparency in the second area where light emission occurs.
2Reliability
If inorganic film layers are extended to increase coverage area, then pixel circuit reliability is improved, but manufacturing complexity increases
