Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for high screen-to-body ratio display devices poses challenges in achieving sufficient light transmittance and optimal positioning of light-collecting modules, such as cameras, while maintaining effective display performance.
Innovation Solution
A display panel design with a first display area and a second display area, where the second area surrounds the first, featuring first and second pixel units with different densities and sub-pixel arrangements, including high-transmittance sub-pixels, to enable both light collection and display functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a light-collecting module is provided on the back side of the display area to increase screen-to-body ratio, then the screen-to-body ratio is improved, but the light transmittance requirement at the light-collecting module becomes more stringent
Solution Approach 1:
The patent applies local quality by differentiating pixel unit densities between two display areas: the first display area (with light-collecting module) uses lower density first pixel units with high-transmittance sub-pixels, while the second display area uses higher density second pixel units. This localized differentiation optimizes light transmittance where the camera is positioned while maintaining overall display quality.
Solution Approach 2:
The patent segments the display area into two distinct regions: a first display area with first pixel units optimized for light collection, and a second display area with second pixel units optimized for display density. This segmentation allows each region to be independently optimized for its specific function, resolving the contradiction between light transmittance and screen-to-body ratio.
2Manufacturing precision
If the density of pixel units is increased to improve display quality, then the display quality is improved, but the light transmittance at the light-collecting module deteriorates
Solution Approach 1:
Different pixel unit densities are applied to different display areas: lower density in the first display area to maximize light transmittance for the camera, and higher density in the second display area to maximize display quality. This local differentiation resolves the contradiction between these two requirements.
Solution Approach 2:
The display panel is segmented into two functional zones with different pixel densities, allowing the first area to prioritize light transmission while the second area prioritizes display resolution, thus resolving the contradiction between light transmittance and display quality.
3Illumination intensity
If high-transmittance sub-pixels are used in the first display area to improve light collection, then the light transmittance is improved, but the display function in that area may be compromised
Solution Approach 1:
The first pixel units with high-transmittance sub-pixels are designed to perform dual functions: they maintain adequate display capability while simultaneously enabling effective light collection for the under-screen camera. This multi-functionality resolves the contradiction between light transmittance and display function.
Solution Approach 2:
The patent merges the display function and light collection function within the first pixel units by incorporating high-transmittance sub-pixels that can both display information and transmit light to the camera, allowing both functions to coexist in the same pixel structure.

AI summary
Embodiments of the present disclosure provides a display panel, a display device, and a display method. A density of a first pixel unit in a first display area is smaller than a density of a second pixel unit in a second display area. In the first pixel unit, a first sub-pixel row includes sub-pixels of different colors arranged along a first direction, and a second sub-pixel row includes first high-transmittance sub-pixels. A plurality of first pixel units are arranged along a second direction to form a first pixel unit column. In one of first pixel unit columns, the first sub-pixel rows and the second sub-pixel rows are alternately arranged. Two closest first sub-pixel rows are located in two adjacent first pixel unit columns and staggered from each other in the first direction.
