Solution Overview

Problem

Existing display technologies face challenges in achieving high resolution while minimizing color edge phenomena, color mixing, and visual granularity, particularly in high-resolution display panels, due to the limitations of manufacturing processes and the use of Sup-Pixel Rendering (SPR) technology.

Innovation Solution

A pixel arrangement structure is introduced where first and second pixel units are alternately arranged in different directions, with sub-pixels arranged to form mirror-symmetrical patterns after rotation, ensuring balanced compactness and pitch between sub-pixels, and incorporating varying light-emitting areas to reduce color mixing and visual granularity.

If sub-pixel sizes are reduced to improve resolution, then resolution is improved, but color mixing risk increases and color edge phenomenon worsens

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies asymmetry by designing pixel units with non-uniform sub-pixel arrangements. Specifically, adjacent pixel units have different sub-pixel configurations, and within each pixel unit, sub-pixels are positioned asymmetrically rather than in a regular grid. This asymmetric design prevents regular color patterns that cause color edges while maintaining small sub-pixel sizes for high resolution.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The patent transitions from traditional two-dimensional grid arrangements to three-dimensional spatial positioning by varying sub-pixel positions in multiple directions. The offset positions and different arrangements in adjacent pixel units create a multi-dimensional distribution pattern that reduces color mixing while preserving resolution.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

If sub-pixel pitch is reduced to improve resolution, then resolution is improved, but visual granularity increases

Engineering Contradiction:

ImproveresolutionVSAvoidvisual granularity

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The asymmetric sub-pixel arrangements within pixel units and the different configurations in adjacent pixel units break up regular visual patterns. This creates a more natural, less granular appearance by preventing the formation of visible pixel grids, thereby reducing visual granularity while maintaining high resolution through small pitch values.

Inventive Principle:

Principle #4Asymmetry

3Measurement precision

If sub-pixel arrangement compactness is increased to improve resolution, then resolution is improved, but color edge phenomenon worsens

Engineering Contradiction:

ImproveresolutionVSAvoidcolor edge

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent uses asymmetric arrangements where sub-pixels within pixel units are positioned non-uniformly, and adjacent pixel units have different sub-pixel configurations. This breaks up regular color patterns that cause color edges while maintaining compact spacing for high resolution.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

Different pixel units have locally optimized sub-pixel arrangements tailored to their specific positions. Each pixel unit's sub-pixels are positioned according to local requirements, with offset positions that prevent color edge formation in specific regions while maintaining overall compactness for high resolution.

Inventive Principle:

Principle #3Local quality

4Ease of manufacture

If traditional regular pixel arrangements are used to simplify manufacturing, then manufacturing ease is improved, but color mixing and color edge phenomena increase

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent divides the display into discrete pixel units, each containing a specific asymmetric sub-pixel arrangement. This segmentation allows for standardized manufacturing of individual pixel units while achieving complex overall patterns that prevent color mixing. The modular pixel unit structure simplifies manufacturing compared to creating entirely irregular patterns across the whole display.

AI summary

The present application relates to a pixel arrangement structure, comprising a plurality of first pixel units and a plurality of second pixel units. The plurality of first pixel units and the plurality of second pixel units are alternately arranged in a first direction and a second direction. The first pixel units and the second pixel units respectively comprises a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. The first sub-pixel is located at one side of an imaginary connecting line between a center of the third sub-pixel and a center of the fourth sub-pixel, and the second sub-pixel is located at another side of the imaginary connecting line between the center of the third sub-pixel and the center of the fourth sub-pixel. After the second pixel units are rotated by a predetermined angle, sub-pixel arrangement structures thereof are mirror-symmetrical to that of the first pixel units.
