Solution Overview

Problem

Mobile phones with notch regions for camera or other elements face challenges in achieving a high screen-to-body ratio due to the occupied screen space, resulting in gaps in image display and reduced screen efficiency.

Innovation Solution

A display apparatus with a substrate featuring first and second display regions, where first active elements are positioned outside the first display region and second active elements are within the second display region, allowing for improved light transmittance and efficient signal line connections between active elements and pixels across both regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a notch region is disposed in the upper part of the screen for photographing elements, then different functions can be realized, but the screen-to-body ratio is reduced and image display region has gaps

Engineering Contradiction:
Improvefunction integrationVSAvoidscreen-to-body ratio
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The active elements for the first display region are extracted from the display region itself and relocated to the border region. This separation allows the first display region to achieve full light transmittance for camera integration while the border region houses the necessary active elements, thus resolving the contradiction between function integration and screen-to-body ratio.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The active elements are moved from the two-dimensional display plane to the border region, utilizing the lateral space dimension. This spatial reconfiguration allows the display region to be fully dedicated to light transmission while the border region provides the functional support, thereby maintaining high screen-to-body ratio while enabling camera integration.

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

2Reliability

If active elements are disposed within the first display region, then pixel control is achieved, but light transmittance is reduced

Engineering Contradiction:
Improvepixel controlVSAvoidlight transmittance
Core Design Contradiction:
ReliabilityVSIllumination intensity

Solution Approach 1:

The active elements are extracted from the first display region and relocated to the border region. This extraction eliminates the obstruction to light transmission in the first display region while maintaining pixel control functionality through electrical connections via signal lines extending from the border region to the pixels.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Signal lines serve as intermediaries, extending from the active elements in the border region to the pixels in the first display region. This intermediary connection maintains the control function while allowing the first display region to remain optically transparent for camera integration.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Illumination intensity

If active elements are disposed outside the first display region in the border region, then light transmittance is enhanced, but device complexity increases

Engineering Contradiction:
Improvelight transmittanceVSAvoidsignal line configuration
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The active elements for both the first display region (border region) and the second display region are merged into a single border region location. This consolidation reduces the overall number of active elements and their associated signal lines compared to having separate active element regions for each display area, thereby managing device complexity while achieving high light transmittance.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The border region serves multiple functions: housing active elements for the first display region, providing signal line routing, and maintaining structural support. This multi-functionality reduces the need for separate dedicated regions for each function, thereby managing overall device complexity while achieving the light transmittance enhancement.

Inventive Principle:
Principle #6Universality (Multi-functionality)
