Display Panel Pixel Layout for Low-Resolution Infrared Sensing Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels with uniform resolution are inadequate for modern small and medium-sized display screens, as they compromise on display quality due to the high wiring density of the backplane circuit, which affects infrared light transmittance and sensor functionality.
Innovation Solution
A display panel with a high-resolution area and a low-resolution area, where the low-resolution area is divided into sub-pixels with a specific RGBG arrangement and staggered pixel rows, reducing the need for sub-pixel borrowing and improving display efficiency, and a manufacturing method involving a substrate with varying pixel definition layer openings and a mask with corresponding through holes for forming the light emitting layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If uniform high-resolution display is used, then display quality is improved, but infrared light transmittance deteriorates due to high wiring density
Solution Approach 1:
The display panel divides the display region into a first region with high pixel density for high-resolution display and a second region with low pixel density for infrared transmission. Different regions have different wiring densities and sub-pixel arrangements, allowing the high-resolution area to maintain quality while the low-resolution area allows infrared light to pass through to the sensor device.
2Adaptability or versatility
If sensor devices are integrated, then smart functionality is improved, but display quality deteriorates due to space occupation in the frame
Solution Approach 1:
The display region is segmented into a first region for high-resolution display and a second region for sensor integration. The second region has reduced pixel density and different sub-pixel arrangements, which reduces the burden on the sensor device and improves infrared detection capability while maintaining acceptable display quality overall.
3Measurement precision
If pixel density is increased, then display resolution is improved, but device complexity increases due to more wiring and circuits
Solution Approach 1:
Instead of uniformly increasing pixel density across the entire display, the patent applies high pixel density only to the first region where it is needed for high-resolution display. The second region uses low pixel density with simplified wiring and sub-pixel arrangements, reducing overall device complexity while maintaining the required display resolution in critical areas.
