Display Panel Layout for Uniform Black Edge Around Sensor Hole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display panels with light-transmissive holes for sensors suffer from non-uniform display black edges due to the limited arrangement of light-emitting pixels, affecting the overall display effect and screen-to-body ratio.
Innovation Solution
A display panel design with a non-light-emitting region between the light-transmissive region and the display region, where the size difference of this region around the light-transmissive hole is controlled to be within 0 μm to 10 μm in the radial direction, ensuring a uniform display black edge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a light-transmissive hole is disposed in the display region to accommodate a photosensitive element, then the screen-to-body ratio is increased and the bezel is narrowed, but the display black edge around the light-transmissive hole becomes non-uniform
Solution Approach 1:
The display region is segmented into a first display region surrounding the light-transmissive hole and a second display region adjacent to the first display region. The first display region has a first pixel arrangement while the second display region has a second pixel arrangement, allowing independent optimization of pixel layout in each segment to achieve uniform black edge display while maintaining high screen-to-body ratio.
Solution Approach 2:
Different pixel arrangement strategies are applied to different local regions: the first display region uses a pixel arrangement optimized for uniform black edge around the light-transmissive hole, while the second display region uses a pixel arrangement optimized for overall display quality. This local quality differentiation resolves the contradiction between screen-to-body ratio and black edge uniformity.
2Adaptability or versatility
If the pixel arrangement around the light-transmissive hole is constrained, then the light-transmissive hole can be positioned for sensor placement, but the display black edge uniformity deteriorates
Solution Approach 1:
The display region is divided into segments with different pixel arrangements. The first display region surrounding the light-transmissive hole uses a pixel arrangement specifically designed to maintain black edge uniformity, while other regions use standard arrangements. This segmentation allows the photosensitive element to be placed flexibly without compromising overall display quality.
Solution Approach 2:
The pixel arrangement is optimized in the radial direction from the light-transmissive hole to ensure uniform black edge display. By considering the radial dimension specifically, the patent achieves both photosensitive element placement flexibility and black edge uniformity that cannot be achieved with conventional uniform pixel arrangements.

AI summary
Provided are a display panel and a display device. The display panel includes a light-transmissive region, a display region at least partially surrounding the light-transmissive region, and a non-light-emitting region located between the light-transmissive region and the display region. In the radial direction of the light-transmissive region, the difference in the size of the non-light-emitting region located around the light-transmissive region is ΔD, where 0 μm≤|ΔD|≤10 μm.
