Corner Display Pixel Layout for Luminance and Color Uniformity

Solution Overview

Problem

Existing display panels experience luminance and color deviations at the boundary between main and corner display areas due to differing pixel arrangements, which affect image quality and aesthetics.

Innovation Solution

A display panel design with a substrate featuring a main display area and a corner display area, where the corner area includes auxiliary pixels arranged to face the main area, with specific sub-pixel configurations and orientations to minimize luminance and color deviations, and a flexible cover window to protect the panel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If different pixel arrangements are used in main display area and corner display area, then display area proportion is increased, but luminance deviation and color deviation occur at the boundary

Engineering Contradiction:

Improvedisplay area proportionVSAvoidluminance uniformity

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

The patent applies local quality by using different pixel arrangement patterns in different regions. Specifically, the main display area uses a first pixel arrangement pattern while the corner display area uses a second pixel arrangement pattern, allowing each region to be optimized for its specific display requirements while maintaining overall display area proportion.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent introduces an intermediary approach by carefully designing the boundary region between main and corner display areas. The auxiliary pixels are strategically positioned and sized to act as a transition zone, mediating between the different pixel arrangements to minimize luminance and color deviations at the boundary.

Inventive Principle:

Principle #24Intermediary (Mediator)

If auxiliary pixels are positioned closer to main display area, then luminance deviation is reduced, but pixel arrangement complexity increases

Engineering Contradiction:

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the display area into distinct regions: main display area, corner display area, and boundary region with auxiliary pixels. This segmentation allows each region to have optimized pixel arrangements while managing overall complexity through structured organization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by using different pixel arrangement patterns in different regions. Specifically, the main display area uses a first pixel arrangement pattern while the corner display area uses a second pixel arrangement pattern, allowing each region to be optimized for its specific display requirements while maintaining overall display area proportion.

AI summary

A display panel includes: a substrate including a main display area and a corner display area; a main pixel located in the main display area and including at least one first main sub-pixel, at least one second main sub-pixel, and at least one third main sub-pixel; and an auxiliary pixel located in the corner display area and including a first auxiliary sub-pixel, a second auxiliary sub-pixel, and a third auxiliary sub-pixel. The number of the at least one first main sub-pixel is greater than each of the number of the at least one second main sub-pixel and the number of the at least one third main sub-pixels, and the first auxiliary sub-pixel is located closer to the main display area than the second auxiliary sub-pixel and the third auxiliary sub-pixel.
