Under-Screen Camera Display Panel with Transition Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with integrated front cameras and sensors cannot achieve a true full-screen display due to the presence of notches or openings, which allow external light to enter photosensitive elements, limiting image display on certain regions of the screen.
Innovation Solution
A display panel design featuring a first display region with high light transmittance for integrating photosensitive components, a transition region with specific pixel circuit distribution to reduce reflectivity differences, and a second display region for normal operation, allowing for under-screen camera integration and full-screen display capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a notch or opening is formed on the display screen to integrate front camera and sensors, then photosensitive elements can be accessed, but the display screen cannot achieve true full-screen display and images cannot be displayed on the region corresponding to the front camera
Solution Approach 1:
The patent moves the photosensitive elements from the front surface to the back surface of the display panel, utilizing the third dimension (depth/thickness) to resolve the conflict between full-screen display and photosensitive element integration. This allows the front display surface to remain fully functional while photosensitive elements are positioned in the rear region.
Solution Approach 2:
The patent introduces a light-transmitting region as an intermediary structure between the light source and the photosensitive elements. This intermediary allows light to pass through the display panel to reach the photosensitive elements on the back surface, enabling both full-screen display functionality and photosensitive element operation without requiring a notch or opening on the front surface.
2Adaptability or versatility
If the first display region has high light transmittance to enable under-screen camera integration, then photosensitive components can be integrated, but the display region may show appearance differences when screen is off
Solution Approach 1:
The patent divides the display panel into different regions with different light transmittance characteristics. The first display region has higher light transmittance to enable under-screen camera integration, while the second display region has lower light transmittance for normal display operation. This local differentiation allows each region to optimize its function while managing appearance differences through controlled light transmission characteristics.
