Display Panel Pixel Layout for Under-Screen Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic devices with integrated front cameras and infrared sensing components cannot achieve full-screen displays due to notching or trepanning on the display panel, which reduces the screen-to-body ratio and affects display area.
Innovation Solution
A display panel design with distinct regions of varying light transmittance and sub-pixel density, allowing for under-screen integration of photosensitive components while maintaining display functionality, including a high light transmittance region for camera integration and a transitional region to minimize display boundaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If notching or trepanning is used to integrate front cameras and infrared sensing components, then photosensitive components can be integrated, but the screen-to-body ratio is reduced and display area is affected
Solution Approach 1:
The patent transitions from lateral integration (notching/trepanning at screen edges) to vertical integration (placing photosensitive components beneath the display panel). This dimensional change allows components to occupy the same lateral footprint without reducing display area, as light passes through the display panel vertically to reach components positioned in the third dimension below the screen surface.
Solution Approach 2:
The display panel structure is designed with nested layers where photosensitive components are positioned within the vertical stack beneath the display panel. The light-transmitting regions of the display panel serve as optical pathways that nest the photosensitive components within the overall device structure without compromising the front display surface.
2Manufacturing precision
If sub-pixel distribution density is increased in certain regions to improve display quality, then display effect is enhanced, but light transmittance in those regions is reduced
Solution Approach 1:
The display panel implements spatially varying sub-pixel distribution density, with higher density in regions prioritized for display quality and lower density in regions prioritized for light transmission. This local optimization allows the system to achieve high display quality where needed while maintaining sufficient light transmittance in regions that require optical access for under-screen components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables full-screen design by integrating photosensitive components under the display while maintaining high display area and improving display effect by reducing visible boundaries between different regions.
Implementation Method 1
a light transmittance of the first display region is greater than a light transmittance of the third display region... External lights can pass through the notch or trepanning on the screen to enter into the photosensitive components located under the screen
Implementation Method 2
a plurality of first sub-pixels distributed in the first display region... a plurality of second sub-pixel groups distributed in the second display region... a plurality of third sub-pixels distributed in the third display region... the single first sub-pixel emits a same color with the plurality of second sub-pixels
