Flexible Display Panel Bending Non-Display Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices have non-display areas, such as bezel areas, that reduce the display area and increase product defects due to the limitations of minimizing sealing lines, which affect adhesive force and product competitiveness.
Innovation Solution
A display device with a flexible substrate and support frame configuration that allows bending of non-display areas towards the support frame, expanding the display area to the front and side surfaces while minimizing or eliminating bezel areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the width of sealing line is reduced to minimize non-display areas, then the bezel area is reduced, but the adhesive force is reduced causing separation phenomenon
Solution Approach 1:
The patent extends the display area from the front surface to the side surfaces of the display device. By bending the non-display area and forming display areas on side surfaces, the sealing line width can be reduced without compromising adhesive force, as the sealing structure is redistributed across multiple surfaces rather than concentrated on the front surface alone.
Solution Approach 2:
The patent employs flexible substrates that can be bent to form display areas on side surfaces. This flexibility allows the sealing line to maintain adequate width for adhesive force while the overall non-display area is minimized through the bent configuration, resolving the contradiction between sealing line width and bezel area.
2Area of stationary object
If the width of sealing line is reduced to minimize non-display areas, then the bezel area is reduced, but separation phenomenon occurs increasing defective product rate
Solution Approach 1:
By forming display areas on side surfaces in addition to the front surface, the patent reduces the required width of sealing lines on the front surface while maintaining overall structural integrity. This dimensional extension prevents separation phenomena and reduces defective product rates while minimizing bezel areas.
3Area of stationary object
If display area is expanded to side surfaces by bending non-display area, then larger display area is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent uses flexible substrates that can be bent into the required configuration. This flexibility simplifies the manufacturing process compared to creating rigid multi-surface structures, as the bending can be achieved through controlled forming processes during assembly, reducing overall manufacturing complexity while expanding display area to side surfaces.

AI summary
In one embodiment, the display device includes a display panel and a support frame. The display panel includes a flexible upper substrate, at least one light emitting diode, and a flexible lower substrate (30). The display panel has a display area formed at a portion corresponding to the light emitting diode, and a non-display area formed at a portion other than the display area. The display panel is coupled to the support frame such that a portion of the non-display area is bent with respect to the display area.
