Solution Overview

Problem

Existing display devices struggle to provide images that meet user needs in varying usage situations, such as differing light conditions and viewing angles, without compromising performance.

Innovation Solution

A display device with a dual operation mode, featuring distinct stacked structures and light blocking patterns in different areas to adjust viewing angle and brightness, utilizing insulating and organic layers with specific thicknesses and arrangements to optimize image quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a uniform stacked structure is used across the entire display panel, then the manufacturing process is simple, but the viewing angle and brightness cannot be adapted to different usage situations

Engineering Contradiction:
Improveadaptability to different usage situationsVSAvoidcomplexity of stacked structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display panel is divided into a first area and a second area with different stacked structures. The first area includes pixels of a first group with a first stacked structure, while the second area includes pixels of a second group with a second stacked structure. This segmentation allows different regions to be optimized for different viewing conditions without requiring the entire panel to be complex.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different stacked structures are applied to different areas of the display panel based on local requirements. The first stacked structure in the first area is optimized for certain viewing conditions, while the second stacked structure in the second area is optimized for other conditions. This local quality approach enables the display to provide optimal image quality for specific usage situations in specific regions.

Inventive Principle:
Principle #3Local quality

2Illumination intensity

If the display panel activates all pixel groups, then the overall brightness is high, but the viewing angle becomes wide which may not be suitable for all situations

Engineering Contradiction:
ImprovebrightnessVSAvoidviewing angle control
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The display panel can dynamically switch between different operation modes by selectively activating different pixel groups. In the first operation mode, pixels of the first group are activated to provide a first viewing angle and brightness level. In the second operation mode, pixels of the second group are activated to provide a second viewing angle and brightness level. This dynamic switching allows adaptation to different usage situations.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the display panel uses a single operation mode, then the device complexity is low, but it cannot meet different user needs in varying usage situations

Engineering Contradiction:
Improveability to meet user needsVSAvoidnumber of operation modes
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display panel is designed with multi-functionality by incorporating multiple operation modes and different pixel groups with distinct characteristics. This allows a single display device to serve multiple purposes and adapt to various usage situations, making it universally applicable across different scenarios without requiring multiple separate devices.

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

AI summary

A display device includes a display panel including a first area including a peripheral region and an emission region of a pixel of a first group; and a second area including a peripheral region and an emission region of a pixel of a second group; at least one insulating layer disposed on the display panel and overlapping the second area; an organic layer disposed on the at least one insulating layer and overlapping the second area; and a light blocking pattern disposed on the organic layer and overlapping the second area. A first opening corresponding to the emission region of the pixel of the second group is formed in the organic layer, and a first light blocking opening corresponding to the first opening is formed in the light blocking pattern.
