Foldable Display Device Minimizing Non-Display Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with multiple panels appear divided when used as a single screen due to non-display regions, particularly at the joints, which also make them prone to breakage and have a wider bezel, limiting their usability and durability.
Innovation Solution
A display device comprising two flexible display units with a foldable housing and a joint portion, where each display unit has a support structure with overlapping surfaces to minimize non-display regions, allowing the units to be adjusted and used as a single large screen without visible division, and enhancing durability by reducing deformation and exposure to impurities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are used to create a large screen, then the display area is increased, but the non-display regions at the joints make the display appear divided
Solution Approach 1:
The patent merges multiple display panels into a single foldable display unit where the panels are connected at foldable joints. When folded, the panels form a continuous display surface without visible non-display regions at the joints, eliminating the divided appearance while maintaining large display area.
Solution Approach 2:
The patent transitions from a planar arrangement of multiple panels to a three-dimensional foldable structure. The foldable joints allow the panels to be arranged in a folded configuration where the display regions overlap or align seamlessly, removing the traditional bezel gaps that cause visual division.
2Area of stationary object
If multiple display panels are connected at joints, then the display area is increased, but the device becomes more prone to breakage
Solution Approach 1:
The patent employs flexible display panels that can bend at the foldable joints without breaking. The flexible nature of the panels allows them to withstand repeated folding and unfolding cycles, significantly improving durability compared to rigid panel connections while maintaining large display area.
3Strength
If the non-display region is made wider to accommodate the joint structure, then the structural integrity is improved, but the bezel area increases
Solution Approach 1:
The patent relocates the structural support function from the two-dimensional bezel area to the three-dimensional foldable joint structure. The joints are positioned at the boundaries between display regions, providing structural integrity without encroaching on the display area or increasing bezel width.
Solution Approach 2:
The patent combines the structural support function with the joint structure itself, rather than requiring separate bezel regions. The foldable joints serve both as connection points for structural integrity and as the boundary between display panels, eliminating the need for additional non-display regions.

AI summary
Display of a display device is made less likely to appear divided when a plurality of display panels are used as one screen. Provided is a display device including two display units and a foldable housing that includes a joint portion between the two display units and supports the two display units. Each display unit includes a display panel including a display region and a non-display region and a support having a first surface overlapped with the display region and a second surface that meets the first surface and is overlapped with the non-display region. The two display units are placed in the housing in an opened state such that the first surfaces of the supports face the same direction and the second surfaces of the supports face each other.
