Display Panel Pixel Density Variation for Under-Screen Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with front cameras have reduced screen-to-body ratios due to the need for hole-making processes in display panels for under-screen camera technology, which prevents full-view displays.
Innovation Solution
A display panel design with a first display area and a second display area at its periphery, where the first area has reduced pixel density to allow light transmission for camera use while maintaining image display capabilities, increasing screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If hole-making processes are performed on display panels to create transparent areas for under-screen cameras, then light can pass through to the camera, but the display panel cannot display images in the transparent area, reducing screen-to-body ratio
Solution Approach 1:
The patent applies local quality by creating different pixel densities in different regions of the display panel. The first display area has reduced pixel density to allow light transmission for camera functionality, while the second display area maintains normal pixel density for full display capability. This spatial variation in pixel density resolves the contradiction by allowing both camera access and image display across different local regions.
Solution Approach 2:
The display panel is segmented into two distinct display areas: a first display area with reduced pixel density for camera light transmission, and a second display area with normal pixel density for standard display. This segmentation allows each region to fulfill its specific function independently, resolving the contradiction between camera integration and full display coverage.
2Adaptability or versatility
If transparent areas are created in display panels for under-screen cameras, then camera functionality is enabled, but full-view display is not achieved
Solution Approach 1:
Different regions of the display panel are assigned different optical properties: the first display area has reduced pixel density to be transparent for camera light transmission, while the second display area maintains normal density for opaque display. This local differentiation enables both camera functionality and full-view display simultaneously.
Solution Approach 2:
The patent resolves the contradiction by adding a dimensional aspect to the display structure - creating a three-dimensional pixel density gradient where pixel density varies across the display surface. This allows the display to simultaneously provide transparent regions for camera access and opaque regions for full display coverage.
3Use of energy by moving object
If pixel density is reduced in the first display area to allow light transmission, then camera light reception is improved, but display resolution in that area is reduced
Solution Approach 1:
The display panel implements local quality by optimizing pixel density for different functional requirements in different regions. The first display area uses reduced pixel density optimized for light transmission to the camera, while the second display area uses higher pixel density optimized for display resolution. Each region's pixel density is locally optimized for its specific function.
Solution Approach 2:
The patent applies parameter changes by varying the pixel density parameter across different regions of the display panel. The first display area has a lower pixel density parameter to maximize light transmission, while the second display area has a higher pixel density parameter to maximize display resolution. This parameter variation resolves the contradiction between light transmission and resolution requirements.
