Transparent Display Region Asymmetry for Under-Screen Camera Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with under-screen camera structures suffer from poor imaging quality due to the diffraction phenomenon, resulting in blurred pictures caused by light passing through the display panel and interfering with the camera's ability to capture clear images.
Innovation Solution
A display panel with a regular display region and a transparent display region, where the transparent areas have the same shape but different placement angles, reducing diffraction and interference patterns, thereby enhancing imaging quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera is disposed under the display area to enable light transmission for picture capture, then the under-screen camera function is achieved, but diffraction phenomenon occurs causing poor imaging quality and blurred pictures
Solution Approach 1:
The patent applies asymmetry by arranging transparent areas with different placement angles (e.g., 0°, 45°, 90°, 135°) rather than uniform alignment. This asymmetric angular distribution disrupts the coherent diffraction patterns that cause bright and dark fringes, thereby improving imaging quality while maintaining the under-screen camera function
Solution Approach 2:
The patent implements local quality by creating transparent areas with varying optical characteristics at different positions. Each transparent area has the same shape but different placement angles, making each local region contribute differently to light transmission. This local variation in orientation reduces overall diffraction interference while preserving light passage to the camera
2Ease of manufacture
If transparent areas are arranged with the same shape and orientation, then manufacturing is simplified, but diffraction-enhanced bright and dark fringes are formed reducing image clarity
Solution Approach 1:
The patent introduces asymmetry in the placement angles of transparent areas (e.g., alternating between 0°, 45°, 90°, 135°) while maintaining uniform shape and size. This asymmetric angular arrangement prevents coherent diffraction interference patterns from forming, thereby improving image clarity without significantly complicating the manufacturing process
Solution Approach 2:
The patent changes the orientation parameter (placement angle) of transparent areas while keeping other parameters (shape, size) constant. By varying the angular parameter across different transparent areas, the diffraction patterns are disrupted, improving image clarity while maintaining manufacturing simplicity through parameter variation rather than structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution improves the imaging quality of the camera by minimizing diffraction-enhanced bright and dark fringes, resulting in clearer pictures and reduced interference, ensuring better contrast and image clarity.
Implementation Method 1
light may pass through the display area of the display panel to the camera, so that the camera can capture a picture
Implementation Method 2
due to diffraction phenomenon, imaging quality of the camera is poor, and pictures taken by the camera are blurred

AI summary
A display panel includes a display region that includes a normal display region and a transparent display region. The normal display region and the transparent display region are connected. The transparent display region includes multiple transparent areas and multiple pixels. The transparent areas have the same shape. For two adjacent transparent areas, a shape of one transparent area has a different placement angle than a shape of another transparent area.
