Flexible Display Module with User-Selected Bending Guide Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display modules lack intuitive and efficient methods for user-controlled bending and folding, limiting their convenience and applicability in various applications.
Innovation Solution
A display module with a display panel and a bender, where bending guide lines are displayed on the panel, allowing users to select a bending line via touch input to bend the panel along a corresponding axis, using an electro-active material for bending and a detector to adjust the bending angle based on user position for optimal viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flexible display modules are designed to fold and change shape, then portability and convenience are improved, but user control over bending is complex and non-intuitive
Solution Approach 1:
The display panel is divided into multiple bending regions separated by bending guide lines, allowing independent control of each segment. Users can select specific regions to bend by touching the corresponding guide lines, rather than controlling the entire panel at once, simplifying the user interface while maintaining flexibility.
Solution Approach 2:
Bending guide lines serve as visual intermediaries between the user and the bending mechanism. The guide lines display on the screen and indicate where bending will occur, providing an intuitive mapping between user touch input and the resulting physical deformation of the display.
2Adaptability or versatility
If multiple bending directions are enabled, then versatility and applicability are improved, but control precision and user intent detection become more difficult
Solution Approach 1:
Different regions of the display panel have different bending characteristics and directions. Each bending guide line corresponds to a specific bending axis and direction, allowing the system to provide precise local control rather than global uniform bending. The display adapts its bending behavior to the specific region touched by the user.
Solution Approach 2:
Instead of detecting complex multi-point touch gestures to determine bending direction, the system inverts the approach by displaying bending guide lines that indicate available directions, and the user simply touches the desired direction. The system then executes bending along that predetermined axis, simplifying the input requirement while maintaining multiple direction options.

AI summary
A display module includes a display part and a bending part. The display part includes a display region for displaying an image and at least one bending guide line. The bending part bends the display part along a bending line which corresponds to the bending guide line, when the bending guide line is selected based on an input signal.
