Flexible Circuit Board Fixing for Narrow Border Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies for achieving narrow border or borderless liquid crystal display products, such as GOA technology, have high technical thresholds and low production yields, leading to increased manufacturing costs.
Innovation Solution
A display panel design that incorporates a flexible circuit board with a fixing member, where the second end of the flexible circuit board is bent toward the display area, ensuring the projection of the flexible circuit board remains in the non-display area, thereby reducing production costs and improving yield.

If GOA technology is used to integrate gate driver onto glass substrate, then narrow border or borderless feature is achieved, but technical threshold is high and production yield is low
Solution Approach 1:
The gate driver circuit is extracted from the glass substrate and relocated to a separate flexible circuit board. This allows the glass substrate to be dedicated solely to display functions, achieving narrow borders while the driver circuit is manufactured separately on flexible substrate, improving production yield by avoiding integration complexity.
Solution Approach 2:
A flexible circuit board serves as an intermediary component between the glass substrate and the control system. It carries the gate driver circuit externally while maintaining electrical connection to the display, enabling borderless design without direct integration on glass, thus resolving the contradiction between border width and production yield.
2Area of stationary object
If GOA technology is used to integrate gate driver onto glass substrate, then narrow border or borderless feature is achieved, but manufacturing cost increases
Solution Approach 1:
The gate driver circuit is extracted from the glass substrate and manufactured separately on flexible substrate. This separation allows standard manufacturing processes to be used for each component independently, reducing the technical threshold and manufacturing cost compared to integrated GOA technology, while still achieving narrow borders.
Solution Approach 2:
The flexible circuit board with driver circuit serves as a separate, replaceable component rather than being permanently integrated into the glass substrate. This approach uses simpler, more cost-effective materials and manufacturing processes for the driver circuit, reducing overall manufacturing cost while maintaining the narrow border feature.

AI summary
The present disclosure provides a display panel and a display device. The display panel comprises an array substrate. The array substrate comprises a display area and a non-display area surrounding the display area. The display area comprises a plurality of active switches and a plurality of pixel units. The non-display area comprises a flexible circuit board and a fixing member. A first end of the flexible circuit board is disposed in the non-display area of the array substrate for driving the pixel units to display. The fixing member disposed on the flexible circuit board. The fixing member bends a second end of the flexible circuit board in a direction toward the display area of the array substrate, so that a projection of the flexible circuit board on the array substrate is located in the non-display area.
