Display Panel Hole Layout With Layered Data Lines for Under-Display Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices face challenges in maximizing the display area while accommodating camera functionality, often requiring non-display areas for camera placement, which can reduce the effective display space and increase load on data lines due to bridge electrodes.
Innovation Solution
A display device design featuring a through hole in the display area allows the camera to capture images through the display panel, eliminating the need for non-display areas and minimizing load differences between data lines by eliminating bridge electrodes in the wiring area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a non-display area is used for camera placement, then the camera can be accommodated, but the display area is reduced
Solution Approach 1:
The patent merges the camera functionality with the display area by placing the camera sensor behind the display panel, allowing the camera to share the same space as the display rather than requiring a separate non-display area. This integration enables both functions to coexist in the same region, maximizing the display area while maintaining camera capability.
Solution Approach 2:
The camera sensor is nested behind the display panel structure, with the camera positioned in a layer beneath the display layers. This nesting arrangement allows the camera to be housed within the overall display assembly without occupying additional external space, thereby preserving the display area while accommodating the camera function.
2Reliability
If bridge electrodes are used to connect data lines, then electrical connection is achieved, but the load on data lines increases
Solution Approach 1:
The patent extracts or removes the bridge electrodes from the data line connection structure. Instead of using bridge electrodes to connect data lines across different layers, the design directly connects data lines vertically through aligned openings in the insulating layers, eliminating the bridge electrode component and reducing the associated electrical load and resistance.
Solution Approach 2:
The patent changes the connection approach from a lateral bridge electrode connection to a vertical direct connection through aligned openings. By transitioning to a vertical alignment and connection method, the design eliminates the need for bridge electrodes and reduces the electrical path length, thereby lowering the load on data lines while maintaining reliable electrical connection.
