Foldable Display Ornamental Member Conceals Film Dislocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display devices experience dislocation issues due to thickness accumulation and different bending radii, leading to a protruding front frame that affects the look-and-feel and grip effect.
Innovation Solution
A foldable display device design featuring a flexible display screen with a protection layer connected to an ornamental member, which creates an activity space between the ornamental member and the frame, allowing the protection layer to shift forward and conceal dislocations during folding, eliminating the need for a front frame and enhancing the screen's flatness and grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a front frame is provided to conceal dislocation of film layers, then the dislocation is hidden, but the front frame protrudes from the screen surface affecting look-and-feel and grip effect
Solution Approach 1:
The patent introduces a new spatial dimension by placing the ornamental member between the frame and display screen in the thickness direction (Z-axis), rather than adding a protruding front frame. This dimensional repositioning allows the concealing function to be achieved without compromising screen surface flatness, as the ornamental member operates in the internal space of the device rather than extending outward.
Solution Approach 2:
The ornamental member serves as an intermediary element that simultaneously performs multiple functions: it conceals the dislocation between film layers, maintains screen surface flatness by not protruding, and provides structural support. This mediator resolves the contradiction by transferring the concealing function from a protruding front frame to an internal ornamental component.
2Manufacturing precision
If a front frame is used to conceal dislocation, then the dislocation is hidden, but the device complexity increases
Solution Approach 1:
The ornamental member is designed to perform multiple functions simultaneously: it conceals dislocation, provides structural support, and contributes to the device's aesthetic appearance. By consolidating these functions into a single component rather than adding separate elements, the solution reduces overall device complexity while achieving the concealment objective.
Solution Approach 2:
The patent merges the concealing function with the existing ornamental member structure, rather than adding a separate front frame component. This integration combines the aesthetic function with the concealment function in one element, thereby reducing the total number of components and simplifying the overall device structure.
3Manufacturing precision
If the protection layer is allowed to shift during folding, then dislocation is concealed, but the screen surface flatness may be affected
Solution Approach 1:
The ornamental member acts as a sacrificial or flexible element that absorbs the dimensional changes during folding. By allowing the ornamental member to move relative to the frame and display screen, it accommodates the protection layer's shift without transmitting this movement to the visible screen surface, thereby maintaining flatness while enabling dislocation concealment.

AI summary
The present disclosure provides a foldable display device and an electronic apparatus, wherein a protection layer as an outermost layer of a flexible display screen is connected to an ornamental member, and an activity space is reserved between the ornamental member and inner side surfaces of a frame. As such, when the flexible display screen is folded, side edges of the protection layer may be shifted forward with respect to a display module, and then the ornamental member may approach the frame in a direction in which the protection layer is shifted, so that the ornamental member may conceal the dislocation occurring when the flexible display screen is folded, along with the protection layer, so as to improve the user's look-and-feel.
