Solution Overview

Problem

In display devices with spatial restrictions, the aesthetic appeal is compromised due to the formation of dead spaces (black areas) adjacent to empty areas where sensor or camera functions are implemented, as pixels cannot be disposed in these areas, leading to a dense wiring structure that deteriorates the visual experience.

Innovation Solution

A display device configuration that includes a display panel with a display area and a non-display area, where scan driving circuits and data lines are strategically positioned outside the display area to connect pixels, bypassing the empty areas and allowing for efficient signal transmission while maintaining an enclosed empty space for sensor or camera functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If pixels are not disposed in the empty area for sensor or camera function implementation, then the sensor or camera function can be implemented, but dead spaces are formed adjacent to the empty area deteriorating aesthetic appeal

Engineering Contradiction:
Improvesensor or camera function implementationVSAvoidaesthetic appeal
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The patent routes scan lines and data lines through the non-display area (a different spatial dimension relative to the display area) to connect pixels on opposite sides of the empty area. This dimensional routing approach allows pixels to be disposed adjacent to the empty area without creating dead spaces, as the wirings bypass the empty area through the non-display area rather than being constrained to route through the display area.

Principle #17Another dimension (Dimensionality change)

2Reliability

If a dense wiring structure is used to apply driving signals to pixels adjacent to the empty area, then pixels can be driven, but the aesthetic sense is deteriorated due to dead space formation

Engineering Contradiction:
Improvepixel driving signal transmissionVSAvoidaesthetic sense
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The patent utilizes the non-display area as an additional routing dimension for scan lines and data lines. By extending these wirings through the non-display area to reach pixels adjacent to the empty area, the patent eliminates the need for dense wiring structures within the display area, thereby preventing dead space formation while maintaining reliable signal transmission to all pixels.

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

3Area of moving object

If the display area is extended to maximize screen size, then the screen area is increased, but empty areas for sensors or cameras must be formed within the display area

Engineering Contradiction:
Improvedisplay areaVSAvoidempty area formation for sensors or cameras
Core Design Contradiction:
Area of moving objectVSAdaptability or versatility

Solution Approach 1:

The patent segments the display panel into distinct display area and non-display area regions. The empty area for sensors or cameras is positioned within the non-display area, separating the functional requirements of display optimization and sensor/camera integration. This segmentation allows the display area to be maximized while accommodating sensor or camera functions without compromising either objective.

Inventive Principle:
Principle #1Segmentation
