Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The presence of a display area above an under-screen camera affects the transmittance, leading to insufficient light input and poor front-photographing imaging performance.
Innovation Solution
A terminal device with a movable light-emitting layer that moves between display and non-display positions, allowing full-screen display and improved light transmittance for camera units by adjusting the orthographic projection areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a display area is placed above the under-screen camera, then the screen-to-body ratio is improved, but the light transmittance is reduced and camera imaging quality deteriorates
Solution Approach 1:
The light-emitting layer is designed as a movable component that can dynamically change its position between a first position (covering the camera area during display mode) and a second position (moving away from the camera area during photographing mode). This dynamic reconfiguration allows the display area to be maximized during normal operation while ensuring adequate light transmission to the camera when needed.
Solution Approach 2:
The light-emitting layer is segmented into a movable first light-emitting layer and a stationary second light-emitting layer. The first light-emitting layer can be moved to different positions, while the second light-emitting layer remains fixed and has lower pixel density in the camera projection area, allowing independent optimization of display and camera functions.
2Illumination intensity
If the first light-emitting layer is moved to the second preset position, then light transmittance is improved, but display area is reduced
Solution Approach 1:
The light-emitting layer is divided into two independent segments: the first light-emitting layer that can be moved to different positions, and the second light-emitting layer that remains stationary. When the first layer is moved to the second preset position to improve light transmittance, the second layer continues to provide display coverage, ensuring that the overall display area is maintained while enabling adequate light transmission for camera operation.
