Solution Overview

Problem

Current display technologies face challenges in achieving a full-screen display effect due to the presence of non-display regions, such as those reserved for sensors, which hinder the integration of camera functionality and design aesthetics in mobile devices and consumer electronics.

Innovation Solution

A display panel design featuring a first display region with organic light-emitting elements and non-rectangular light-transmitting holes that surround the second display region, allowing external light to enter the camera while maintaining normal display functionality, thereby increasing the screen-to-body ratio and reducing diffraction for improved image forming quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a non-display region is designed at the top of the display to accommodate sensors, then camera functionality is achieved, but the screen-to-body ratio is reduced and full-screen display effect cannot be achieved

Engineering Contradiction:

Improvecamera functionalityVSAvoidscreen-to-body ratio

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent merges the camera sensor region with the display region by making the light-transmitting holes non-rectangular and positioning them to avoid overlapping with organic light-emitting elements. This integration eliminates the need for a separate non-display region, achieving both camera functionality and full-screen display effect simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent transitions from a traditional rectangular hole arrangement to a non-rectangular hole design that operates in a different geometric dimension. By changing the shape and orientation of light-transmitting holes, the camera sensor can be positioned within the display area without compromising either functionality or aesthetics.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of manufacture

If rectangular light-transmitting holes are used, then manufacturing is simplified, but diffraction occurs and image forming quality is reduced

Engineering Contradiction:

Improvehole fabricationVSAvoidimage forming quality

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent applies asymmetry by designing non-rectangular light-transmitting holes with specific shapes that are optimized to reduce diffraction effects. These asymmetric shapes are strategically positioned and oriented to minimize interference patterns while maintaining ease of manufacturing through standard fabrication processes.

Inventive Principle:

Principle #4Asymmetry

3Area of stationary object

If light-transmitting holes overlap with organic light-emitting elements, then display area is maximized, but camera light reception is blocked

Engineering Contradiction:

Improvedisplay areaVSAvoidlight reception for camera

Core Design Contradiction:

Area of stationary objectVSIllumination intensity

Solution Approach 1:

The patent applies local quality by creating spatially varying properties within the display structure. The non-rectangular light-transmitting holes are positioned in specific locations where they transmit light to the camera sensor without overlapping with organic light-emitting elements, thereby maintaining both display integrity and camera functionality in different local regions.

Inventive Principle:

Principle #3Local quality
