Solution Overview

Problem

Existing display technologies face challenges in meeting different display requirements for transmitting light of various central wavelengths, particularly when multiple display requirements exist, as they typically rely on a single light emission color resist to improve contrast, which limits their versatility.

Innovation Solution

A display panel design that incorporates first-band color pixels with at least two light-emitting devices emitting the same color, paired with a first-band light emission color resist comprising sub-color resists transmitting light of different central wavelengths, allowing for controlled light emission to meet diverse display needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a single light emission color resist is used to improve display contrast, then the contrast is improved, but the ability to satisfy multiple display requirements for different central wavelengths is lost

Engineering Contradiction:

Improvedisplay contrastVSAvoidability to satisfy multiple display requirements

Core Design Contradiction:

Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The light emission color resist is segmented into multiple sub-color resists, each transmitting light of different central wavelengths. This segmentation allows the system to maintain high contrast for each specific wavelength while providing versatility to satisfy multiple display requirements by selectively activating different sub-color resists.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The color resist layer is designed with multi-functionality by incorporating multiple sub-color resists that can transmit different central wavelengths. This universal design enables the same color resist layer to satisfy multiple display requirements simultaneously, rather than requiring separate resist layers for each wavelength.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple sub-color resists transmitting different central wavelengths are incorporated, then the adaptability to meet different display requirements is improved, but the device complexity increases

Engineering Contradiction:

Improveability to satisfy different display requirementsVSAvoidcolor resist layer structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple sub-color resists transmitting different central wavelengths are merged into a single integrated color resist layer. This combining approach maintains adaptability to meet different display requirements while avoiding the complexity of multiple separate resist layers, as all sub-color resists are incorporated within one unified structure.

Inventive Principle:

Principle #5Merging (Combining)

3Device complexity

If light-emitting devices emit light of the same color, then the simplicity of the light emission source is maintained, but the ability to transmit light of different central wavelengths is limited

Engineering Contradiction:

Improvelight emission source configurationVSAvoidlight transmission wavelength range

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The color resist layer acts as an intermediary between the light-emitting devices and the final output. Even though the light-emitting devices emit light of the same color, the color resist layer with multiple sub-color resists selectively transmits different central wavelengths, thereby expanding the wavelength range without complicating the light emission source itself.

Inventive Principle:

Principle #24Intermediary (Mediator)
