Display Substrate Bent Wiring for Narrow-Frame Camera Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in display device design is accommodating a camera while maintaining a full-screen and narrow-frame layout, as the camera's space requirements conflict with the need for a maximized display region.
Innovation Solution
A display substrate with a peripheral region that includes a first and second wire, arranged in a bent configuration to pass through a display region and an opening peripheral region, providing electrical signals and allowing for capacitor formation to compensate for varying sub-pixel loads, thereby optimizing space for a narrow-frame design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the camera is arranged at an outer side of the display region, then the camera has sufficient space, but the display region cannot be maximized and the frame cannot be narrow
Solution Approach 1:
The patent integrates the camera into the display region by utilizing the opening (notch) area, transforming the traditional side-arrangement into a dimensionally integrated layout. This allows the camera to be positioned within the display region rather than at the outer side, maximizing the display area while providing sufficient space for the camera through the opening structure.
2Device complexity
If wires are arranged straight through the peripheral region, then the wiring is simple, but insufficient space remains for load compensation capacitors
Solution Approach 1:
The patent employs bent wire configurations (first bent portion and second bent portion) instead of straight wires. These bent portions create additional space within the peripheral region that can be utilized for arranging load compensation capacitors, thereby maintaining wiring functionality while enabling sufficient space for reliability-critical compensation components.
Solution Approach 2:
The wire structure is segmented into multiple portions (first wire with first bent portion, second wire with second bent portion) that pass through different regions (first display region, opening peripheral region, second display region). This segmentation allows optimized spatial arrangement for both wiring and capacitor placement.
3Area of stationary object
If the peripheral region space is reduced for narrow-frame design, then the frame becomes narrow, but space for wires and capacitors becomes insufficient
Solution Approach 1:
By implementing bent portions in the wires rather than straight configurations, the patent efficiently utilizes the limited peripheral region space. The curved/bent wire paths create compact arrangements that fit within the reduced peripheral area while still providing adequate space for capacitor placement and maintaining proper wire routing.

AI summary
A display substrate, a manufacturing method thereof and a display apparatus are provided. The display region of the display substrate includes an opening, and a first display region and a second display region located at opposite sides of the opening, and the peripheral region includes an opening peripheral region at least partially located in the opening. The display substrate further includes a first wire and a second wire arranged on a same layer; the first wire and the second wire pass through the first display region, the opening peripheral region and the second display region, sequentially; in the opening peripheral region, the first wire includes a first bent portion, the second wire includes a second bent portion, and the first bent portion and the second bent portion are arranged side by side along the first direction.
