Display Panel Gate Line Segmentation for Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels face challenges with increased bezel width due to the placement of gate and data drivers, leading to higher manufacturing costs and propagation delays in gate signals, which affect display quality.
Innovation Solution
The display panel is designed with a structure where first-gate lines and second-gate lines are connected one-to-one, with the gate driver and data driver positioned on one side, reducing bezel width and propagation delay by alternating the connection of odd and even numbered gate lines in different areas, allowing for efficient signal scanning and improved display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the gate driver and data driver are independently manufactured and bonded, then the display panel can be assembled, but the manufacturing cost increases
Solution Approach 1:
The gate driver and data driver are integrated into a single driver unit that is bonded to one side of the display panel. This merging of previously separate components reduces the number of bonding steps and assembly operations, thereby lowering manufacturing cost while simplifying the overall driver assembly process
2Ease of operation
If the gate driver is disposed at a side portion of the display panel, then the gate driver can be accessed, but the bezel width increases
Solution Approach 1:
The driver configuration transitions from occupying lateral space (increasing bezel width) to utilizing the vertical dimension by bonding to one side of the panel. This dimensional repositioning allows the gate driver to remain accessible while minimizing the horizontal bezel width
3Ease of operation
If the gate line extends in a horizontal direction, then the gate driver can be positioned at the side, but the propagation delay of the gate signal increases
Solution Approach 1:
The gate line is divided into multiple segments with different extension directions. By segmenting the gate line structure, the signal propagation path is optimized to reduce delay while maintaining the side positioning of the gate driver for ease of operation

AI summary
A display panel includes a plurality of blocks. The block includes a plurality of first-gate lines extending in a first direction and a plurality of second-gate lines extending in a second direction different from the first direction. The first-gate lines are connected to corresponding second-gate lines one-to-one in the block. The second-gate lines disposed in a first area of the block are connected to odd numbered first-gate lines among the plurality of first-gate lines one-to-one. The second-gate lines disposed in a second area of the block are connected to even numbered first-gate lines among the plurality of first-gate lines one-to-one.
