Under-screen Camera Pixel Compensation for Light Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The under-screen camera area in mobile devices lacks pixels, impacting the front camera's shooting effect due to reduced light transmittance and resulting in blurry imaging.
Innovation Solution
A display screen design with multiple camera areas, each comprising pixel units and light-transmitting areas, arranged to compensate for each other, allowing increased light transmittance and maintaining normal display functionality, thereby enhancing the front camera's shooting performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pixels are arranged in the opening area of the screen to maintain normal display, then display function is maintained, but light transmittance is reduced resulting in blurry imaging of the under-screen camera
Solution Approach 1:
The opening area is divided into multiple camera areas (first camera area, second camera area, third camera area) with different pixel arrangements. Each camera area has pixels arranged in specific patterns (circle, triangle, square, diamond shapes) to optimize both display and light transmittance for different camera functions
Solution Approach 2:
Different regions of the opening area have different pixel densities and arrangements tailored to specific camera requirements. The first camera area has pixels arranged to support the first camera, the second camera area has pixels arranged for the second camera, and the third camera area has pixels for the third camera, allowing each region to optimize its local function
2Illumination intensity
If the opening area has no pixels to increase light transmittance, then light transmittance is improved, but the area has no display function
Solution Approach 1:
The pixel units in different camera areas can be dynamically controlled to be transparent or opaque based on camera operation status. When cameras are active, pixels can become transparent to allow light through; when cameras are inactive, pixels can display normally, making the system adaptive to different operational states
Solution Approach 2:
The optical properties of pixel units are changed based on operational requirements. By adjusting parameters such as pixel transparency, density, and arrangement patterns, the system can switch between optimizing for light transmittance (when camera is active) and display quality (when camera is inactive)

AI summary
A display screen and a display device are disclosed. The display screen includes: a first camera area including a first pixel unit and a first light-transmitting area; a second camera area including a second pixel unit and a second light-transmitting area; and a display area surrounding the first camera area and the second camera area, wherein a position of the first pixel unit in the first camera area corresponds to a position of the second light-transmitting area in the second camera area, and a position of the second pixel unit in the second camera area corresponds to a position of the first light-transmitting area in the first camera area.
