Display Panel Mesh Power Lines for Under-Screen Camera Light Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with under-screen cameras face low light transmittance in low Pixels Per Inch (PPI) regions, which hampers the display effect and camera performance.
Innovation Solution
The display panel design optimizes the signal lines in the low PPI region by rearranging the conductive lines of the meshed power supply line, reducing wiring and improving light transmittance by creating a more efficient layout that allows ambient light to pass through, including a structure where the first conductive line extends from the high PPI region to the low PPI region and is connected by second and third conductive lines, with these lines arranged to intersect and overlap with pixel units in a specific pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a high PPI region and low PPI region are designed for under-screen camera, then the display panel can support camera imaging function, but the light transmittance in the low PPI region becomes low
Solution Approach 1:
The display panel is divided into a first display region (high PPI) and a second display region (low PPI), with different pixel densities in different areas. This segmentation allows the low PPI region to have larger pixel spacing, which improves light transmittance while the high PPI region maintains display quality. The camera imaging function is supported by the low PPI region's optical transparency.
2Illumination intensity
If the pixel density in the first display region is reduced to improve light transmittance, then the light transmittance improves, but the display quality in that region deteriorates
Solution Approach 1:
Different regions of the display panel have different pixel densities tailored to their specific functions. The first display region (high PPI) maintains high display quality for normal viewing areas, while the second display region (low PPI) has reduced pixel density optimized for light transmittance to support the under-screen camera. This local quality differentiation resolves the contradiction between display quality and light transmittance.
