Cover Panel Through-Hole Layout for Under-Display Camera Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in maintaining high-quality image display while accommodating camera modules, as they often compromise display quality when integrating these modules.
Innovation Solution
A display device design featuring a cover panel with a seating groove and through-hole configuration that stably houses electronic modules like camera modules, using a manufacturing process that includes forming a through-hole and seating groove in the cover panel to ensure precise alignment and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a camera module is placed in the display area, then the displayed image area is increased, but the display quality in that area deteriorates
Solution Approach 1:
The display area is segmented into two distinct regions: a first area with high pixel resolution for normal image display, and a second area with lower pixel resolution where the camera module is disposed. This segmentation allows the camera module to be integrated without compromising the overall display quality, as the reduced resolution area is specifically allocated for camera functionality rather than general image display.
2Reliability
If the electronic module is securely fixed in the cover panel, then the module stability is improved, but the device complexity increases
Solution Approach 1:
The cover panel is designed with localized structural features - a through-hole and a seating groove - specifically at the position where the camera module needs to be mounted. The seating groove provides localized support and positioning for the camera module's lower surface, while the through-hole allows the protruding portion to pass through and be secured from the rear. This local quality approach achieves secure module fixation without requiring complex overall panel redesign.
3Length of stationary object
If the cover panel thickness is reduced to accommodate the camera module, then the device portability is improved, but the protection capability deteriorates
Solution Approach 1:
Instead of reducing the overall cover panel thickness, the design utilizes the vertical dimension by creating a seating groove that extends downward from the rear surface of the cover panel. This allows the camera module to be positioned in a recessed area, effectively using the thickness dimension to accommodate the module without compromising the protective function of the main cover panel structure. The display panel remains adequately protected while the camera module is housed in the grooved region.

AI summary
A display device includes: a display panel and a cover panel disposed under the display panel, including at least one layer for protecting the display panel, and provided with a through-hole and a seating groove defined therein to allow an electronic module to be disposed. The through-hole extends along a thickness direction, the seating groove is connected to an t end of the through-hole and overlaps the through-hole in a plan view, the seating groove has a width greater than a diameter of the through-hole, the seating groove is defined under the through-hole, and the seating groove has a depth from about 10 micrometers to about 100 micrometers.
