Solution Overview

Problem

Existing display devices face challenges in reducing the load on signal lines, which can affect the efficiency and resolution of the display.

Innovation Solution

The display device is designed with data lines and sensing lines arranged in a specific configuration, where sub-pixels are connected to reduce the distance between data lines and sharing of lines among adjacent sub-pixels, and the use of inorganic light emitting diodes connected in parallel to enhance light emission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the number of data lines is increased to improve pixel resolution, then the display quality is improved, but the load on signal lines increases

Engineering Contradiction:
Improvepixel resolutionVSAvoidload on signal lines
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent segments the data lines into even and odd groups, with even data lines spaced further apart than odd data lines. This segmentation allows for reduced overall line density while maintaining pixel resolution by strategically positioning lines to serve multiple sub-pixels.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each data line is designed to serve multiple sub-pixels across different pixels. Even data lines connect to first sub-pixels of multiple pixels, while odd data lines connect to second sub-pixels, allowing each line to perform multiple functions and reducing the total number of lines needed.

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

2Manufacturing precision

If the distance between data lines is reduced to increase pixel density, then the pixel resolution is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvepixel densityVSAvoiddata line configuration
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent employs asymmetric spacing between data lines, where even data lines are spaced at a greater distance than odd data lines. This asymmetric configuration optimizes the balance between pixel density and manufacturing complexity by creating a more manageable line distribution pattern.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

Different regions of the display have different data line spacing characteristics. Odd data lines are positioned closer together in certain regions while even data lines maintain larger spacing, allowing local optimization of pixel density without uniformly increasing overall complexity.

Inventive Principle:
Principle #3Local quality

3Quantity of substance

If the number of data lines is decreased to reduce load, then the signal line load is reduced, but the pixel connectivity is compromised

Engineering Contradiction:
Improvenumber of data linesVSAvoidpixel connectivity
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent extends data line connectivity into the pixel row dimension by having even data lines connect to first sub-pixels across multiple adjacent pixels and odd data lines connect to second sub-pixels across multiple adjacent pixels. This dimensional extension maintains comprehensive pixel connectivity while reducing the total number of data lines required.

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

AI summary

A display device includes data lines arranged in a first direction, the data lines extending in a second direction; and pixels including sub-pixels arranged in the first direction, the sub-pixels being electrically connected to the data lines. A distance between closest even data lines of the data lines is greater than a distance between adjacent sub-pixels of the sub-pixels, and each pixel includes first sub-pixels emitting light of a first color and second sub-pixels emitting light of a second color. Two first sub-pixels of two pixels adjacent to each other in the first direction are electrically connected to one even data line among the even data lines.
