1Productivity

If a typical rectangular pixel array is used, then the display device has a simple and regular structure, but the driving efficiency is reduced when non-traditional shapes are required

Engineering Contradiction:
Improvedriving efficiencyVSAvoidpixel array structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The pixel array is divided into multiple pixel columns with different numbers of pixels (first pixel column with i pixels, second pixel column with j pixels where i≠j). This segmentation allows each column to be independently configured according to the desired display shape, improving driving efficiency for non-traditional shapes while managing structural complexity through systematic division

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs asymmetric pixel column configurations where different pixel columns have different numbers of pixels. This asymmetry enables the display device to efficiently render non-traditional shapes (triangular, pentagonal) by matching the pixel distribution to the geometric requirements, thereby improving productivity without excessive complexity

Inventive Principle:
Principle #4Asymmetry

2Productivity

If all pixels in a pixel column are connected to the same data line, then the connection structure is simple, but the number of gate signal scans increases reducing driving efficiency

Engineering Contradiction:
Improvedriving efficiencyVSAvoiddata line connection structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The second pixel column is divided into two groups (first pixel group with k pixels connected to first data line, second pixel group with j-k pixels connected to second data line). This segmentation reduces the number of gate signal scans required by allowing independent data line control, thereby improving driving efficiency while managing connection complexity through organized grouping

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic pixel activation where pixels are turned on in synchronized groups based on their data line connections. The first pixel group and second pixel group can be activated independently through different data lines, reducing the total number of gate signal scans needed and improving driving efficiency

Inventive Principle:
Principle #15Dynamics

3Productivity

If pixels are activated sequentially to simplify control, then the control structure is simple, but the display refresh rate and efficiency are reduced

Engineering Contradiction:
Improvedisplay refresh rateVSAvoidpixel activation control
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements periodic pixel activation where pixels are turned on in synchronized groups corresponding to different data lines. This periodic grouping allows multiple pixel groups to be activated in a systematic sequence, improving display refresh rate by efficiently utilizing gate signal cycles while maintaining manageable control complexity through regular patterns

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

Pixels from different pixel columns are merged into corresponding pixel groups (first pixel group and second pixel group) that are activated simultaneously through synchronized control. This merging allows concurrent activation of multiple pixels, improving display refresh rate while simplifying control by treating grouped pixels as unified units

Inventive Principle:
Principle #5Merging (Combining)
