Display Substrate Signal Routing Around Camera Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in display apparatus design is to accommodate a camera device within the display screen while maintaining a full-screen and narrow frame design, as the camera's installation requires a frame position that compromises the display's maximization and uniformity.
Innovation Solution
A display substrate with a base substrate featuring a first and second signal line that surrounds a first opening region, allowing the camera to be integrated within the display region, with the signal lines' overlapping regions forming compensation capacitors to balance load and maintain display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the camera device is arranged on a side outside the display region, then the camera can be installed without occupying display area, but the display screen cannot achieve full-screen and narrow frame design
Solution Approach 1:
The camera device is integrated within the display region by nesting the opening region inside the display area. The signal lines wind around this nested opening region, allowing the camera to be positioned within the display boundaries while maintaining full-screen appearance.
Solution Approach 2:
The signal lines transition from straight linear paths to winding paths that surround the opening region. This dimensional change in the signal line configuration allows them to navigate around the camera opening while still connecting to all necessary pixel regions.
2Adaptability or versatility
If a place is reserved for the camera device in the display region, then the camera can be integrated with the display screen, but the display region area is reduced
Solution Approach 1:
The opening peripheral region is designed with specific local characteristics - it surrounds the opening region and contains winding portions of signal lines. This localized structural quality allows the signal lines to adapt to the camera opening while maintaining overall display functionality.
3Ease of operation
If the signal lines pass through the opening peripheral region in different directions, then the signal lines can connect to all pixel regions, but the overlapping regions increase the area occupied
Solution Approach 1:
The first and second signal lines are configured to overlap in the opening peripheral region, merging their paths through this specific area. This combining of signal line routes allows them to both navigate the opening region efficiently while minimizing the total area occupied by reducing redundant spacing.

AI summary
A display substrate and a display apparatus. In the display substrate, the first signal line sequentially passes through the first display region, the opening peripheral region and the second display region along a first direction, and includes a first lead portion and a first winding portion that are in the opening peripheral region and connected to each other; the first winding portion partially surrounds the opening; the second signal line provides a second display signal to the pixel array, passes through the peripheral region of the opening along a second direction intersecting with the first direction, includes a second winding portion in the peripheral region of the opening and partially surrounds the opening. The first lead portion and the second signal line have a first overlapping region, and the first winding portion and the second winding portion have a second overlapping region.
