Driving Connector Layout for Narrow-Bezel Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices have a significant bezel area that reduces the effective display area, necessitating a reduction in the space occupied by drivers to enhance the visibility of the display.
Innovation Solution
The integration of a driving module with a driving integrated circuit, gate driver, and multiplexers on a non-display area, utilizing flexible substrates and transparent transmissive areas to minimize bezel width, and the inclusion of shielding electrodes to prevent electrical interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If drivers are disposed in the non-display area, then the display area is surrounded and structural functionality is provided, but the bezel area increases reducing the effective display area
Solution Approach 1:
The patent merges the driving integrated circuit and gate driver into a single integrated driving module located in the non-display area. This consolidation reduces the total area occupied by drivers compared to having separate driver components, thereby minimizing the bezel area while maintaining all necessary display functionality.
Solution Approach 2:
The patent utilizes a flexible substrate that can be bent or folded, allowing the driving module to occupy less planar area on the display panel. By transitioning from a rigid two-dimensional layout to a flexible three-dimensional structure, the driving components are compacted into a smaller footprint, reducing the bezel width.
2Area of stationary object
If the driving module is integrated on the non-display area, then the bezel area is reduced, but electrical interference between components may occur
Solution Approach 1:
The patent introduces a shielding electrode as an intermediary element between the driving integrated circuit and the gate driver. This shielding electrode acts as a protective barrier that blocks electrical interference between the two components while allowing them to coexist in the same driving module, thus enabling bezel reduction without compromising electrical stability.
3Area of moving object
If flexible substrates are used to minimize bezel width, then the display area is enlarged, but manufacturing complexity increases
Solution Approach 1:
The patent divides the display device into distinct functional modules: a flexible substrate containing the driving integrated circuit, a separate gate driver, and connection structures. This segmentation allows each component to be manufactured and tested independently before final assembly, reducing the overall manufacturing complexity despite the use of flexible substrates.

AI summary
A display device includes a display panel and a driving connector connected to the display panel and from which driving signals are provided to the display panel, the driving connector including a driving integrated circuit, a gate pad through which a first driving signal is output from the driving connector to the display panel, a first input pad through which the first driving signal is input to the driving connector from outside thereof, and a gate driver which connects the gate pad to the first input pad and includes a first substrate and a transistor on the first substrate and including a source electrode connected to the first input pad and a drain electrode connected to the gate pad. Within the driving connector, the transistor and the driving integrated circuit are in order from the first substrate.
