Display Device Scan Line Bypass Routing for Hole Area

Solution Overview

Problem

Existing display devices have a significant dead space due to non-display areas, which reduces the size of the display area and affects the overall efficiency of the device.

Innovation Solution

A display device with a substrate that includes a hole area, a display area adjacent to the hole area, and a non-display area. The device features multiple scan drivers and scan lines that are electrically connected and include bypass lines to navigate around the hole area, allowing for efficient connection and operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a non-display area is provided for components, then components can be disposed outside the display area, but dead space increases and display area size decreases

Engineering Contradiction:

Improvecomponent arrangementVSAvoiddisplay area size

Core Design Contradiction:

Ease of manufactureVSArea of stationary object

Solution Approach 1:

The scan lines are configured to extend in multiple directions including bypass lines that route around the hole area, transitioning from a simple linear path to a multi-dimensional routing pattern that navigates through the substrate thickness and lateral space to connect scan drivers on opposite sides without occupying additional display area

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The scan line is divided into multiple segments including straight lines and bypass lines that are electrically connected, allowing the line to navigate around the hole area while maintaining electrical continuity and reducing the impact on display area

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If scan lines are extended to connect scan drivers on opposite sides, then component placement flexibility increases, but line complexity and routing difficulty increase

Engineering Contradiction:

Improvescan driver placement flexibilityVSAvoidscan line routing complexity

AI summary

A display device includes a substrate including a hole area, a display area, and a non-display, a first scan driver disposed adjacent to a first side of the display area, a second scan adjacent to a second side of the display area opposite to the first side of the display area, and to which a scan signal, different from a signal applied to the first scan driver, is applied, a first scan line including a first straight line along a first direction and a first bypass line bypassing along a boundary of the hole area, a second scan line including a second straight line extending along a direction opposite to the first direction and a second bypass line bypassing along the boundary of the hole area, and a data line extending along a second direction.
