Solution Overview

Problem

Conventional RGB stripe displays require at least two columns to form a white color, as each column lacks all necessary colors, limiting the efficiency of multi-color displays.

Innovation Solution

An image device with pixel groups arranged in a predetermined matrix form, including at least four color dots (e.g., red, green, blue, and white) in a 2×2 or larger matrix, allowing for repeated sequences of color dots in both row and column directions, enabling all multi-primary colors to be present in a single row or column.

1Device complexity

If conventional RGB stripe display uses separate columns for each color, then color separation is achieved, but at least two columns are needed to form white color

Engineering Contradiction:

Improvenumber of columnsVSAvoidcolor formation capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent combines multiple color dots (red, green, blue, and white) into a single pixel group that can be arranged in a 2×2 or larger matrix. This merging allows all necessary colors to be present within one column, eliminating the need for multiple columns to form white color while maintaining color separation through the matrix arrangement of individual dots.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent transitions from a linear stripe arrangement to a two-dimensional matrix arrangement of color dots within each pixel group. This dimensional change enables all colors to coexist in a single column by utilizing the spatial distribution within the matrix, thereby reducing the number of columns required while preserving color formation capability.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If all multi-primary colors are provided in a single row or column, then subpixel rendering efficiency improves, but pixel group arrangement complexity increases

Engineering Contradiction:

Improvesubpixel rendering efficiencyVSAvoidpixel group arrangement

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the display into discrete pixel groups, each containing a specific matrix arrangement of color dots. This segmentation allows for systematic organization of multiple colors within each group, making the complex arrangement manageable through repeated identical patterns while enabling efficient subpixel rendering when all colors are available in a single column.

Inventive Principle:

AI summary

An image device includes a plurality of pixel groups. Each pixel group includes a plurality of dots arranged in a predetermined identical matrix form, and each pixel group has at least one first color dot, at least one second color dot, at least one third color dot and at least one fourth color dot. Any repeated sequence of consecutive color dots in a row direction and in a column direction comprise at least one first color dot, at least one second color dot, at least one third color dot, at least one fourth color dot. The advantage of the invention is to provide all multi-primary colors in a single row or column so that by using subpixel rendering method, black and white lines can be formed in rows or columns, thus reducing the number of columns in a multi-primary colors display.
