Gate Driver Segmentation for Narrow Bezel Multi-Panel Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices have a significant bezel size due to the placement and configuration of gate drivers, which limits the reduction of non-display areas between multiple display panels, affecting the overall aesthetic and functional efficiency.
Innovation Solution
The configuration of gate drivers in multiple non-display areas, including sub-gate drivers, allows for the reduction of the bezel size by optimizing the placement and connection of gate drivers to gate lines, with the number and positioning of gate drivers adjusted to minimize the width of non-display areas, particularly the intermediate non-display area, to be approximately half the size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If gate drivers are placed in a single large non-display area, then the connection to gate lines is simplified, but the bezel size becomes significantly larger
Solution Approach 1:
The gate driver is divided into multiple sub-gate drivers (first sub-gate driver, second sub-gate driver, third sub-gate driver, fourth sub-gate driver) that are distributed across different non-display areas. This segmentation allows the bezel size to be reduced while maintaining the necessary driver functionality through distributed architecture.
Solution Approach 2:
The gate drivers are arranged in both first and second directions perpendicular to the gate lines, utilizing two-dimensional spatial distribution rather than single-direction placement. This dimensional approach optimizes the use of non-display areas and reduces the overall bezel size.
2Area of stationary object
If the number of gate drivers is increased to reduce bezel size, then the non-display area is minimized, but the device complexity increases
Solution Approach 1:
Different sub-gate drivers are positioned in different non-display areas (first non-display area, intermediate non-display area, second non-display area) with specific local functions. Each sub-gate driver connects to specific ends of gate lines, optimizing the local utilization of non-display spaces while minimizing the total non-display area width.
3Area of stationary object
If sub-gate drivers are distributed across multiple non-display areas, then the intermediate non-display area width is reduced to approximately half, but the connection complexity increases
Solution Approach 1:
The gate driver functionality is segmented into multiple sub-gate drivers distributed across different non-display areas, which reduces the intermediate non-display area width to approximately half while maintaining simplified connection paths through localized connectivity.
Solution Approach 2:
Instead of connecting all gate drivers to all gate lines, the invention inverts the connection approach by having each sub-gate driver connect to specific ends of gate lines in a distributed manner, which simplifies the overall connection configuration despite the multiple drivers.

AI summary
A display device and a multi-panel display device are disclosed. In one aspect, the display panel includes a plurality of display areas, an intermediate non-display area, a first non-display area, and a second non-display area. The display areas are spaced apart from one another in the first direction or the second direction. The intermediate non-display area is formed between the display areas. The first non-display area is formed at the outermost position in the first direction. The second non-display area is formed at the outermost position in the second direction. The gate driver is formed in the first non-display area, the second non-display area, and the intermediate non-display area and is configured to supply a gate signal to gate lines formed in each display area.
