Flexible Display Expansion Using Gesture-Triggered Screen Unfolding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with flexible displays face challenges in expanding the screen area when objects or additional applications are displayed, leading to reduced screen size or hidden content, and physical buttons for expansion require additional space.
Innovation Solution
An electronic device with a processor-controlled display that detects user gestures to expand or reduce the screen areas dynamically, allowing seamless expansion and reduction of the display without the need for physical buttons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a physical button is used to expand the flexible display, then the display expansion function is achieved, but additional space is required for mounting the button
Solution Approach 1:
The patent removes the physical button from the device structure and replaces it with a gesture-based control system. The processor detects gestures (such as tapping or sliding motions) on the display surface to trigger display expansion, eliminating the need for separate physical expansion buttons and associated mounting spaces.
Solution Approach 2:
The patent substitutes the mechanical button-pressing system with an electronic gesture recognition system. Instead of requiring physical contact with a button, the system uses touch-sensitive gestures detected by the display's sensing capabilities to control display expansion, transitioning from mechanical to electronic control.
2Ease of operation
If the screen area is reduced to accommodate objects or applications, then the device portability is maintained, but the screen real estate for applications is reduced
Solution Approach 1:
The patent implements a dynamic display area that can change its size based on operational needs. The display can expand when applications require more space and contract when portability is prioritized, allowing the screen real estate to adapt between conflicting requirements rather than being fixed.
Solution Approach 2:
The patent changes the physical parameter of display area size dynamically. By controlling the flexible display to expand or contract, the system adjusts the screen real estate parameter to match the current operational context, whether that be maximum application space or compact portability.
3Adaptability or versatility
If multiple applications are displayed simultaneously on a small screen, then the functionality is enhanced, but the screen space for each application is reduced
Solution Approach 1:
The patent divides the display into multiple independent display areas that can be controlled separately. When multiple applications are running, the display can be segmented into different regions, each dedicated to a specific application, allowing simultaneous operation while maintaining adequate space for each application's execution.
Solution Approach 2:
The patent utilizes the third dimension of space by expanding the display in the vertical direction rather than just horizontally. By allowing the display to extend upward from the base screen area, the system creates additional display dimensions that accommodate multiple applications without compromising the horizontal screen real estate.

AI summary
According to an embodiment, an electronic device comprises a display and a processor, wherein the processor can be configured to: control the display so that a first screen is displayed in a first area of the display during a first state in which a second area among the first area and the second area of the display is not exposed to the outside of the electronic device; detect an event; control the display so that a first object corresponding to the event is displayed in at least a partial area of the first area, the first object being displayed in at least a part of the first screen; confirm the input of a first gesture of a user into the area in which the first object is displayed, while the area ratio of the size of the first object, with respect to the size of the first area, is greater than or equal to a designated ratio; and control the electronic device so that the state of the display is changed from the first state to a second state in which the first area and the second area of the display are exposed to the outside of the electronic device.
