Display Panel Wiring Layout for Reduced Dead Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing use of display apparatuses with various functions, such as cameras and sensors, leads to a problem of 'dead areas' due to wiring that bypasses these components, resulting in reduced effective display space.
Innovation Solution
A display panel design with a substrate featuring distinct areas for components, where lines such as data or scan lines are strategically routed to bypass these areas, reducing the dead space by optimizing line placement and density between and around the component areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wirings are routed around component areas (camera, sensor) to provide access and functionality, then the components can be properly connected and function, but dead areas increase and effective display space decreases
Solution Approach 1:
The patent routes wirings through the thickness dimension of the display panel rather than only in the planar display area. By extending signal lines through multiple layers and utilizing the Z-axis space, the design allows wirings to pass beneath or through component areas without occupying valuable 2D display space, thus reducing dead areas while maintaining component connectivity
Solution Approach 2:
The patent implements a multi-layer structure where signal lines, data lines, and component interconnections are nested across different layers of the display panel. This nesting approach allows multiple wiring paths to be stacked vertically, enabling wirings to access components without creating visible dead areas on the display surface
2Adaptability or versatility
If multiple component areas are added to increase display functions, then the display apparatus becomes more versatile, but the dead areas around these components increase
Solution Approach 1:
The patent divides the wiring system into separate, independently routed signal lines for different components. Each component area has its own dedicated signal transmission path, allowing complex multi-component configurations without requiring a single complex wiring harness. This segmentation simplifies the overall wiring complexity by breaking it into manageable, modular segments
Solution Approach 2:
The patent employs a standardized multi-layer wiring architecture that can accommodate multiple different component types (camera, sensor, etc.) using the same basic routing structure. This universal wiring framework reduces complexity by providing a repeatable pattern that can be applied to various component configurations without redesigning the entire wiring system

AI summary
A display panel includes a substrate including a first area and a second area that are spaced apart from each other in a first direction; a plurality of display elements located in a display area, the display area being adjacent to the first area and the second area; and a plurality of lines extending in a second direction that intersects the first direction, the plurality of lines being electrically respectively connected to the plurality of display elements, wherein the plurality of lines include: a first line and a second line adjacent to each other and bypassing along an edge of the first area; and a third line and a fourth line adjacent to each other and bypassing along an edge of the second area, wherein the first area and the second area are different from each other in at least one of size or shape.
