Under-Display Camera Screen Segmentation for Full-Screen Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic terminals with full screens experience poor display effects due to the need for a mounting hole or slot for the front camera, which compromises the aesthetics and functionality.
Innovation Solution
A display screen with two areas, one having higher light transmittance than the other, allowing the front device to operate without displaying when enabled, and displaying fully when disabled, by using a passive matrix light emitting diode screen and an active matrix light emitting diode screen with independent driving units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting hole or slot is provided on the display screen to install the front camera, then the front camera can function properly, but the full screen display effect deteriorates
Solution Approach 1:
The display screen is divided into two distinct display areas: a first display area with higher light transmittance for camera operation and a second display area with lower light transmittance for normal display. This segmentation allows each area to serve its specific function independently, resolving the contradiction between camera functionality and full screen display effect.
Solution Approach 2:
Different regions of the display screen are assigned different light transmittance properties. The first display area has higher light transmittance to allow light passage for the front camera, while the second display area has lower light transmittance for optimal display performance. This local differentiation enables both camera function and display quality to coexist.
2Reliability
If the first display area has higher light transmittance for camera operation, then the front device can operate properly, but the display resolution may be reduced
Solution Approach 1:
The light transmittance parameter is varied across different display areas to meet different functional requirements. The first display area uses higher light transmittance for camera operation, while the second display area uses lower light transmittance for high-quality display, allowing both functions to operate at optimal performance levels.
3Adaptability or versatility
If independent driving units are used for the first and second display areas, then each area can be controlled independently, but the device complexity increases
Solution Approach 1:
The driving unit is designed to perform multiple functions: it can independently control the first display area for camera operation, independently control the second display area for normal display, and coordinate both areas to work together. This multi-functionality enables flexible operation modes while managing complexity through a unified control architecture.

AI summary
The present disclosure relates to a display screen and an electronic terminal. The display screen includes a display region including a first display area and a second display area. The first display area has a screen as a first screen, and the second display area has a screen as a second screen. A light transmittance of the first screen is greater than a light transmittance of the second screen. The electronic terminal includes a terminal body, the above display screen, a front device and a control device. The above display screen and electronic terminal can improve the full screen display effect.
