Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices with high screen-to-body ratios face challenges in integrating sensor modules without compromising display effect, particularly in maintaining a high screen-to-body ratio and achieving uniform display quality.
Innovation Solution
The implementation of an array substrate with distinct display and non-display areas, including an optical component setting area, where the pixel density in the second display area is lower than in the first, reducing lead connections and allowing for pixel compensation and light-sensitive device integration within the display area, thereby increasing the effective display area and enhancing display uniformity.

Engineering Contradiction Analysis
1Area of stationary object
If the screen-to-body ratio is increased to achieve a borderless visual effect, then the display area is expanded, but the integration of sensor modules becomes more difficult and display uniformity deteriorates
Solution Approach 1:
The display area is segmented into a first display area with higher pixel density and a second display area with lower pixel density. This segmentation allows different regions to serve different functions: the first display area provides high-quality display, while the second display area accommodates sensor modules and compensation elements, thus enabling sensor integration without compromising overall display uniformity.
Solution Approach 2:
Different pixel densities are applied to different regions of the display area. The first display area maintains high pixel density for optimal display quality, while the second display area uses lower pixel density to provide space for sensor modules and compensation elements. This local differentiation allows the system to achieve both high display quality and successful sensor integration.
2Manufacturing precision
If the pixel density is uniformly high across the entire display area, then the display quality is improved, but the space for lead connections and sensor integration is reduced
Solution Approach 1:
The display area is divided into two segments with different pixel densities. The first display area uses high pixel density to ensure excellent display quality, while the second display area uses lower pixel density to create sufficient space for lead connections and sensor module integration, thus resolving the conflict between display quality and integration space.
Solution Approach 2:
The patent applies different pixel densities to different local regions of the display area. The first display area maintains high pixel density for superior display quality, while the second display area adopts lower pixel density to provide necessary space for lead connections and sensors, achieving local optimization for both display quality and integration requirements.
3Area of stationary object
If the pixel density in the second display area is reduced to accommodate sensor modules, then the space for sensor integration is increased, but the display uniformity deteriorates
Solution Approach 1:
A compensation element is introduced as an intermediary component in the second display area. This compensation element compensates for the display non-uniformity caused by the reduced pixel density and the presence of sensor modules, thereby maintaining overall display uniformity while providing sufficient space for sensor integration.
Solution Approach 2:
The pixel density parameter is changed differently across different regions of the display area. The first display area maintains high pixel density while the second display area uses lower pixel density. Additionally, compensation elements are introduced to adjust and balance the display parameters, ensuring uniformity across the entire display area despite the regional differences in pixel density.
4Area of stationary object
If the first non-display area is reduced to increase effective display area, then the effective display area is increased, but the space for lead connections is reduced
Solution Approach 1:
The patent utilizes the second display area with lower pixel density to provide additional space for lead connections within the display area itself, rather than relying solely on the non-display area. This dimensional redistribution of space allows the first non-display area to be reduced, thereby increasing the effective display area while still providing sufficient space for lead connections through the second display area.
