Display Module With Arc-Shaped Cover for Smaller Camera Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display modules with front cameras under the screen require a transparent region for light passage, reducing the screen ratio as the area cannot display images.
Innovation Solution
A display module design with a protective cover featuring an arc-shaped concave surface corresponding to the through-hole region, allowing the camera lens to be positioned away from the light-emitting side, and a through-hole region with a size equal to or smaller than the lens, reducing the non-display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transparent region is reserved in the display panel for the front camera, then light can pass through for camera operation, but the screen ratio is reduced because the display panel cannot display images in that region
Solution Approach 1:
The protective cover is designed with an arc-shaped concave surface corresponding to the through-hole region, allowing the camera lens to be positioned on the light-emitting side of the display panel. This curved structure enables the lens to focus light through the through-hole while minimizing the non-display area, thereby improving screen ratio while maintaining camera functionality
Solution Approach 2:
The camera module is positioned in a three-dimensional space above the display panel rather than being flat-mounted, with the lens extending toward the light-emitting side. This spatial arrangement allows the light path to be optimized through the arc-shaped protective cover, reducing the footprint of the non-display region while ensuring proper light transmission for the camera sensor

AI summary
A display module, including a display panel, a protective cover, and a camera module, is provided. The display panel includes a through-hole region provided with a through-hole, and a non-through-hole region. The protective cover is disposed on a light-emitting side of the display panel, and the camera module is disposed on a side facing away from the light-emitting side of the display panel. A lens of the camera module is disposed corresponding to the through-hole, a side of the protective cover close the display panel has an arc-shaped concave surface, and the arc-shaped concave surface is disposed corresponding to the through-hole.
