Solution Overview

Problem

Conventional display technologies face limitations in achieving uniform color representation due to the arrangement of sub-pixels in a single direction, leading to non-uniform colors and suboptimal display effects, especially when trying to increase pixel density without altering sub-pixel size.

Innovation Solution

The proposed pixel arrangement structure alternates sub-pixels in adjacent rows to incline in horizontally opposite directions, allowing for mutual light compensation and improving color uniformity, which enhances the display effect by ensuring that sub-pixels in the first row and second row compensate each other in the light exit direction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If sub-pixels are arranged in a single direction to increase pixel density, then pixel density is improved, but color uniformity deteriorates

Engineering Contradiction:
Improvepixel densityVSAvoidcolor uniformity
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The patent applies asymmetry by alternating the inclination direction of sub-pixels in adjacent rows. Odd rows have sub-pixels inclining in one direction while even rows have sub-pixels inclining in the opposite direction, creating a symmetric alternating pattern that compensates for directional color non-uniformity while maintaining high pixel density

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The patent changes the orientation parameter of sub-pixels from a fixed single direction to alternating directions between adjacent rows. This parameter change allows the display to achieve both high pixel density and improved color uniformity through mutual compensation of light emission characteristics

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If sub-pixel size is kept fixed to improve display effect, then sub-pixel quality is improved, but pixel density deteriorates

Engineering Contradiction:
Improvedisplay effectVSAvoidpixel density
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent transitions from a one-dimensional linear arrangement to a two-dimensional arrangement with alternating inclination directions. This dimensional change allows sub-pixels to be packed more efficiently while maintaining fixed size, achieving both high pixel density and good display effect through the alternating pattern

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
