Foldable Display Area Switching Across Hinge Angle Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable smartphones with multiple displays are expensive and face design limitations, making them less appealing to younger users due to high cost and design constraints.
Innovation Solution
A method for controlling the operation of display areas in a foldable device by using a first, second, and third display areas, where the first angular range activates a first display area and a second angular range activates a second angular range activates a second angular range activates a second angular range activates a third angular range activates a third display area, where the first angular range is detected, and based on the angular range, different functions are executed and displayed in the third display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display areas are used in foldable smartphones, then functionality and user interaction are enhanced, but device cost increases and design limitations occur
Solution Approach 1:
The patent implements dynamic display area activation based on detected angular ranges. The system transitions between different display configurations (first display area, second display area, third display area) as the device moves through different angular positions during folding/unfolding. This dynamic approach allows a single physical display structure to provide multiple functional modes, enhancing versatility without requiring multiple separate display components.
Solution Approach 2:
The flexible display serves multiple functions across different angular ranges. The same physical display area is reused in different configurations - acting as first display area when unfolded beyond first threshold angle, second display area when folded within second threshold angle, and third display area for graphical interfaces in intermediate ranges. This multi-functionality reduces the need for additional display components, addressing the cost concern.
2Ease of operation
If multiple display areas are used in foldable smartphones, then user interaction is enhanced, but design limitations occur
Solution Approach 1:
The system dynamically adjusts the active display area and graphical interface based on the detected angular range. As the device transitions between folded and unfolded states, the controller automatically activates appropriate display areas and presents context-appropriate interfaces. This dynamic adaptation enhances user interaction by providing relevant functionality for each usage state without requiring complex manual configuration.
Solution Approach 2:
The display system automatically detects the angular range and activates the appropriate display configuration without user intervention. The controller monitors the angular position and self-adjusts which display area is active and what graphical interface is presented, reducing the need for complex user settings or manual mode switching while improving ease of operation.

AI summary
A method for controlling an operation of a foldable device including a first display area and a second display area divided based on a foldable area, and a third display area, includes: detecting that an angle between the first display area and the second display area is unfolded to a first value within a first angular range; displaying a graphical interface of a first function in the third display area based on the first value; executing a selected second function based on a user input selecting the second function in the graphical interface; detecting that the angle between the first display area and the second display area is changed to a second value within a second angular range; and performing a third function through at least a partial area of the first display area or the second display area based on the second value.
