Variable-Pixel Display Substrate for Full-Screen Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The arrangement of front-facing elements such as cameras and sensors on all-screen display panels hinders the improvement of the screen-to-panel ratio, as these elements occupy non-display areas.
Innovation Solution
A display substrate design with varying pixel density, featuring a high-density first display sub-area for display and a low-density second sub-area for accommodating these elements, allowing for improved screen transparency and panel ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If front-facing elements (camera, sensor, fingerprint recognition area) are arranged on the front face of the display panel, then these functional elements can be integrated, but the screen-to-panel ratio is reduced due to occupied non-display areas
Solution Approach 1:
The patent merges the fingerprint recognition area with the display area by making the fingerprint sensing region transparent and integrating it into the pixel structure. The fingerprint sensor electrodes are formed within the pixel electrodes, allowing the fingerprint recognition function to be combined with the display function in the same physical space, thereby eliminating the need for separate non-display areas for these functional elements.
2Manufacturing precision
If uniform high pixel density is maintained across the entire display area, then display quality is maximized, but the ability to accommodate additional functional elements is reduced
Solution Approach 1:
The patent applies local quality by creating different pixel density regions within the same display panel. The first pixel array maintains high pixel density for primary display areas, while the second pixel array uses low pixel density for regions where functional elements like cameras and sensors need to be integrated. This allows each region to have optimized characteristics - high resolution where needed and transparency/functionality where required.

AI summary
Disclosed are a display substrate, a drive method therefor, a display apparatus, and a high-precision metal mask template, a display region of the display substrate comprising a first display sub-region having high pixel distribution density and a second display sub-region having low pixel distribution density. As the pixel distribution density in the second display sub-region is low, components such as a camera can be arranged in the second display sub-region, thus increasing the screen occupation ratio of the display substrate by means of reducing the local pixel distribution density in order to increase the light transmittance of the screen.
