Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in reducing the bezel area to achieve a slim design, which affects the overall aesthetic appeal and functionality of devices.
Innovation Solution
The display apparatus is designed with a novel layout of pixel groups and scan lines, including multiple gate drivers and data drivers positioned in the peripheral area, and a specific arrangement of scan and data lines to minimize bezel width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the bezel area is reduced to achieve a slim design, then the visual appeal and compactness are improved, but the complexity of signal routing and driver placement increases
Solution Approach 1:
The display panel is divided into multiple pixel groups (first, second, third, and fourth pixel groups) that are independently controlled by separate scan lines. This segmentation allows the signal routing to be divided into manageable sections, reducing the overall routing complexity while achieving a thinner bezel design.
Solution Approach 2:
The patent introduces horizontal scan lines that extend in a second direction (horizontal) to connect scan lines in the first direction (vertical). This dimensional change allows for more efficient signal distribution across the display area, enabling reduced bezel width without proportionally increasing routing complexity.
2Area of stationary object
If multiple gate drivers and data drivers are positioned in the peripheral area, then the display area is maximized, but the complexity of driver arrangement increases
Solution Approach 1:
Multiple gate drivers and data drivers are integrated into a single peripheral area rather than being distributed separately. This merging approach consolidates the driver components, making the arrangement more manageable while maximizing the display area by minimizing the space required for driver placement.
3Area of stationary object
If scan lines are extended to connect multiple pixel groups, then the display coverage is improved, but the signal transmission path length increases
Solution Approach 1:
The scan lines are segmented into multiple independent paths (first scan line, second scan line, third scan line, fourth scan line) that connect to different pixel groups. This segmentation allows for more efficient signal distribution across the display area, reducing the overall transmission path length compared to a single continuous scan line approach.
