Solution Overview

Problem

The presence of wirings around multiple areas in display apparatuses increases the dead area, which is a challenge when integrating components like cameras and sensors within the display area.

Innovation Solution

A display panel design that minimizes the dead area by strategically arranging signal lines and power lines in intermediate and peripheral areas, allowing for components such as cameras and sensors to be integrated within the display area without increasing the non-display space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wirings are arranged around multiple areas (camera, sensor) inside the display area, then these components can be integrated into the display apparatus, but the dead area increases

Engineering Contradiction:
Improveintegration of camera and sensorVSAvoiddead area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent applies dimensionality change by routing wirings through the peripheral area and intermediate area rather than only around the components. Specifically, wirings extend from the peripheral area through the intermediate area to reach the display area, allowing components to be positioned within the display area without increasing the dead area. This spatial reconfiguration enables multi-dimensional wiring paths that reduce the dead area while maintaining component integration.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent segments the wiring paths into distinct regions: peripheral area, intermediate area, and display area. By dividing the wiring layout into these segments, the patent can optimize each region's function - the peripheral area handles external connections, the intermediate area acts as a transition zone, and the display area maintains minimal dead space. This segmentation allows wirings to bypass components efficiently while maintaining connectivity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If components are integrated within the display area, then functionality increases, but the dead area around components increases

Engineering Contradiction:
Improvefunctional integrationVSAvoidnon-display space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent introduces the intermediate area as an intermediary zone between the peripheral area and the display area. This intermediate area serves as a mediator that allows wirings to transition smoothly from the peripheral region to the display region without creating dead areas around components. The intermediate area acts as a buffer zone that optimizes wiring paths while maintaining component integration within the display area.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A display panel (10) includes a substrate including a first area (RA1) and a second area (RA2) that are spaced apart from each other in a first direction; a plurality of display elements located in a display area (DA), 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 (DL1) and a second line (DL2) adjacent to each other and bypassing along an edge of the first area (RA1); and a third line (DL3) and a fourth line (DL4) 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.
