Sensor-Region Display Panel Layout for Uniform Brightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display non-uniformity occurs in regions with optical electronic elements due to reduced pixel density, leading to brightness inconsistencies and compromised display effects.
Innovation Solution
A display panel design with a first display region for sensors and a second surrounding region, featuring an array substrate with data lines that connect to sub-pixels in the first region, ensuring even load distribution and improved uniformity by avoiding disconnected data lines.

Engineering Contradiction Analysis
1Illumination intensity
If pixel density is reduced in the region with optical electronic elements, then transparency of this region is improved, but display non-uniformity occurs in this region
Solution Approach 1:
The patent applies local quality by differentiating the structure between the first display region (with sensor) and second display region (without sensor). In the first display region, data lines are extended and connected to sub-pixels to maintain uniformity, while in the second region, conventional data line routing is used. This localized structural adjustment ensures each region has the appropriate characteristics for its function.
Solution Approach 2:
The display panel is segmented into two distinct display regions: a first display region containing optical electronic elements (sensors) and a second display region without such elements. This segmentation allows independent optimization of each region - the first region can have reduced pixel density for transparency while the second maintains full density for display quality, resolving the uniformity issue.
2Illumination intensity
If data lines are not connected to sub-pixels in the first display region, then transparency is improved, but load difference increases and display uniformity deteriorates
Solution Approach 1:
The patent implements preliminary action by extending data lines through the first display region and pre-establishing connections to sub-pixels before the display operation begins. This ensures that data lines have consistent load characteristics from the outset, preventing display uniformity issues that would arise from disconnected or improperly loaded data lines in the sensor region.
