Alternating Pixel Arrangement for Down-Screen Camera Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The design of a down-screen camera in display devices increases the screen-to-body ratio but poses a challenge in achieving high light transmittance and effective display at the position where the photosensitive element is embedded, leading to a granular sensation and reduced display quality.
Innovation Solution
The implementation of a display panel with a first display region having a lower pixel density than the second display region, where pixel units are alternately arranged to reduce the pixel per inch (PPI) and interconnected signal lines are optimized to enhance light transmittance, avoiding the granular sensation while ensuring normal pixel unit operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the pixel density is reduced in the first display region to improve light transmittance, then the light transmittance is improved, but the display quality deteriorates due to granular sensation
Solution Approach 1:
The patent applies local quality by creating two distinct display regions with different pixel densities. The first display region has a lower pixel density to improve light transmittance for the down-screen camera, while the second display region maintains normal pixel density for standard display quality. This localized differentiation allows each region to optimize for its specific function without compromising the other.
Solution Approach 2:
The display region is segmented into multiple pixel unit rows (first pixel unit rows and second pixel unit rows) with alternating arrangements. This segmentation allows the patent to create distinct zones with different pixel densities while maintaining overall display functionality, resolving the contradiction between light transmittance and display quality.
2Illumination intensity
If the pixel per inch is reduced to enhance light transmittance, then the light transmittance is improved, but the resolution deteriorates
Solution Approach 1:
The patent implements local quality by reducing pixel density only in the first display region where the down-screen camera is located, while maintaining normal pixel density in the second display region. This selective approach improves light transmittance where needed without sacrificing overall display resolution.
Solution Approach 2:
The patent resolves the resolution concern by extending the display region in spatial dimensions. By adding more display regions and using alternating pixel unit rows, the patent compensates for the reduced pixel density in the first region, maintaining overall resolution through increased display area rather than increasing pixel density.
3Area of moving object
If the screen to body ratio is increased by embedding the photosensitive element, then the screen to body ratio is improved, but the light transmittance at the embedding position deteriorates
Solution Approach 1:
The patent applies local quality by creating a first display region with reduced pixel density specifically at the position where the down-screen camera (photosensitive element) is embedded. This localized reduction in pixel density improves light transmittance at the embedding position while maintaining normal pixel density in other areas to preserve overall display quality and achieve high screen-to-body ratio.

AI summary
A display panel and a display device are provided. The display panel includes first display region and second display region at least partially surrounding the first display region. In the first display region, along a row direction, the first pixel unit in the first pixel unit row is between two adjacent second pixel units in the second pixel unit row, and the second pixel unit in the second pixel unit row is between two adjacent first pixel units in the first pixel unit row. The first pixel circuit and the second pixel circuit are connected to a same first or second signal line. The first pixel unit connected to the first pixel circuit and the second pixel unit connected to the second pixel circuit are located in adjacent rows or columns.
