Display Substrate Pixel Layout for Under-Screen Component Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The arrangement of front camera, earphone, fingerprint recognition area, and physical buttons on display devices hinders the improvement of the screen-to-body ratio in full-screen panels.
Innovation Solution
A display substrate design with distinct sub-areas of varying pixel density, including a high-density first display sub-area, a low-density second display sub-area, and a transition sub-area with intermediate pixel density, arranged to minimize brightness differences and allow for functional elements while maintaining high screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are arranged in the front display area, then functional requirements are met, but the screen-to-body ratio deteriorates
Solution Approach 1:
The patent applies local quality by creating different display areas with different pixel densities. The first display area has high pixel density for visual display, while the second display area has low pixel density specifically for component arrangement. This allows components to be placed in the low-density area without affecting the visual quality in the high-density area, thus meeting functional requirements while maintaining screen-to-body ratio.
2Adaptability or versatility
If pixel density is reduced in the second display area, then components can be arranged, but visible dark strips appear at the interface
Solution Approach 1:
The patent introduces a transition display area as an intermediary between the first high-density display area and the second low-density display area. This transition area has intermediate pixel density that gradually changes from high to low, acting as a buffer zone that smooths the interface between the two distinct display areas. This eliminates the abrupt density change that causes visible dark strips, while still allowing component arrangement in the low-density region.

AI summary
A display substrate, a method for driving the same, a display device, and a high-precision metal mask are provided. The display area includes a first display sub-area in which pixels are distributed at a high density (e.g., a high resolution), and a second display sub-area in which pixels are distributed at a low density (e.g., a low resolution), and a transition display sub-area, with a distribution density of pixels (a resolution) between the distribution density of pixels in the first display sub-area and a distribution density of pixels in the second display sub-area, is arranged between the first display sub-area and the second display sub-area.
