Display Device Border Width Reduction via Direct Pin Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices have a wide border region due to gate line and data line fan-shaped wiring regions, which affects both the appearance and display effect, particularly in miniaturized electronic products.
Innovation Solution
The design omits gate line and data line fan-shaped wiring regions by directly connecting panel pins on the display panel edge to circuit board pins, with connecting lines on the control circuit board, allowing the control circuit board to be folded behind the display panel without occupying additional space, thereby reducing the border width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If gate line and data line fan-shaped wiring regions are used to connect display panel pins to control circuit board pins, then reliable electrical connection is achieved, but the border width becomes too large affecting appearance and display effect
Solution Approach 1:
The patent extracts and removes the fan-shaped wiring regions from the border area. By directly connecting display panel pins to control circuit board pins without intermediate fan-shaped wiring, the non-display region width is significantly reduced while maintaining electrical connection functionality through the direct pin-to-pin connection path.
Solution Approach 2:
The patent transitions from a two-dimensional fan-shaped wiring layout on the same plane to a three-dimensional connection structure where the control circuit board is folded behind the display panel. This spatial reconfiguration eliminates the need for wide border wiring regions while preserving electrical connectivity.
2Volume of moving object
If fan-shaped wiring regions are included in the border area, then complete electrical connection between gate lines, data lines and control circuit is achieved, but the display device overall size increases
Solution Approach 1:
The patent merges the control circuit board with the display panel by folding the control circuit board behind the display panel. This integration eliminates separate wiring regions and reduces the overall device volume while maintaining complete electrical connection between all components through the compact folded structure.
3Area of stationary object
If conventional pin connection method with fan-shaped wiring is used, then electrical connection is established, but non-display space is occupied reducing display area ratio
Solution Approach 1:
The patent extracts and eliminates the fan-shaped wiring structures from the border region. By implementing direct pin-to-pin connections between the display panel and control circuit board, the wiring complexity is reduced and the display area ratio is increased as no additional non-display space is occupied by wiring regions.

AI summary
A display device includes a display panel and a control circuit board configured to provide a driving signal to the display panel. The display panel includes a plurality of pixel structures of which pixel structures arranged in one row are connected to one gate line. Pixel structures arranged in one column are connected to one data line. The control circuit board includes a driving chip, an end portion of each of the gate lines and an end portion of each of the data lines are respectively provided with panel pins. The control circuit board is provided with circuit board pins to be electrically connected with the panel pins, and connecting lines through which pins of the control circuit board are connected to the circuit board pins. A spacing between adjacent circuit board pins is larger than a spacing between adjacent pins of the driving chip connected with the circuit board pins.
