Display Panel End-Mounted Drivers Narrow Border Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display panels face challenges in achieving a narrow border design due to the spatial occupation of source and gate drivers, which limits the reduction of frame size and results in larger frame widths.
Innovation Solution
The display panel design positions the source driver at one end and the gate driver at the opposite end of the array substrate, with connecting lines that gradually increase in length to intersect with scan lines, allowing for compact arrangement and preventing overlap, thereby enabling a narrow border or borderless display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the source driver and gate driver are mounted at the side positions of the array substrate, then the drivers can be easily installed and connected, but the frame width increases and narrow border design cannot be achieved
Solution Approach 1:
The patent inverts the conventional mounting arrangement by placing the source driver and gate driver at opposite ends of the array substrate instead of at side positions. This inversion allows the drivers to be positioned within the display area boundaries, enabling narrow border or borderless design while maintaining driver functionality and connection capabilities.
Solution Approach 2:
The patent transitions from a side-position mounting approach to an end-position mounting approach, effectively changing the spatial dimension of driver placement. By moving drivers along the length dimension to the ends rather than positioning them at the sides, the frame width is reduced while driver installation and connection remain feasible.
2Area of stationary object
If the connecting lines are arranged to gradually increase in length and sequentially connect to scan lines, then the layout becomes compact and narrow border is achieved, but the wiring complexity increases
Solution Approach 1:
The patent segments the connecting lines into multiple distinct lines, each with a specific length and connection point to scan lines. This segmentation allows for systematic arrangement of drivers at the ends and organized routing of connecting lines, reducing overall wiring complexity while achieving compact layout and narrow border design.
