Solution Overview

Problem

Conventional display devices with right-angled corners can lead to poor recognition of information displayed at these corners, causing user discomfort and are not aesthetically appealing, especially with the increasing demand for visually appealing designs.

Innovation Solution

A display device with rounded corners and a step-like arrangement of pixels and gate driver stages, where each stage protrudes in the extension direction of the gate line, optimizing the layout to minimize the display area and enhance aesthetics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If right-angled corners are used in display devices, then manufacturing is simple and structure is straightforward, but user recognition of corner information is poor and aesthetics are compromised

Engineering Contradiction:

Improvecorner shapeVSAvoidmanufacturing simplicity

Core Design Contradiction:

ShapeVSEase of manufacture

Solution Approach 1:

The patent applies curvature by rounding the corners of the display device instead of using right-angled corners. This transforms the sharp angular geometry into a curved form, improving aesthetics and user comfort while maintaining manufacturing feasibility through standard rounding processes.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The gate driver is divided into multiple stages arranged in a step-like pattern along the rounded corner. This segmentation allows the driver to adapt to the curved geometry while maintaining functional integrity, resolving the conflict between aesthetic curvature and manufacturing simplicity.

Inventive Principle:

Principle #1Segmentation

2Shape

If pixels are arranged in a step-like shape to match rounded corners, then aesthetics and corner information recognition are improved, but display area is reduced

Engineering Contradiction:

Improvepixel arrangement shapeVSAvoiddisplay area

Core Design Contradiction:

ShapeVSArea of moving object

Solution Approach 1:

The step-like pixel arrangement is applied locally at the corner regions where rounded shapes are present, while the main display area maintains its full extent. This localized adaptation improves corner aesthetics and information recognition without significantly compromising the overall display area.

Inventive Principle:

Principle #3Local quality

3Shape

If gate driver stages are arranged in a step-like shape, then rounded corner aesthetics are achieved, but device complexity increases

Engineering Contradiction:

Improvegate driver shapeVSAvoidgate driver structure

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

The gate driver is segmented into multiple stages that follow the rounded corner geometry. Each stage handles a portion of the gate lines, and this modular segmentation makes the complex arrangement more manageable and manufacturable despite the increased structural complexity.

Inventive Principle:

Principle #1Segmentation
