Foldable Display Automatic Mode Switching via Opening Degree
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display devices with multiple screens require users to perform inconvenient operations to change display modes, such as switching between single and dual screen modes, which can be time-consuming and cumbersome.
Innovation Solution
A foldable display apparatus with rotatable casings and sensors that automatically detect the opening degree and inclination of the screens, allowing the display control unit to dynamically adjust the display mode and orientation based on the selected application and user interactions, thereby eliminating the need for manual mode changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display apparatus provides multiple display modes (single screen and dual screen modes), then the adaptability of the display apparatus is improved, but the ease of operation deteriorates because users need to perform manual operations to switch between display modes
Solution Approach 1:
The display control unit dynamically changes the display mode based on real-time detection of opening degree and inclination. The system transitions from static manual mode selection to dynamic automatic adaptation, where the display mode is continuously adjusted according to the detected physical state of the device
Solution Approach 2:
The opening degree detecting unit and inclination detecting unit provide feedback about the device's physical state to the display control unit. This feedback loop enables the system to automatically determine and switch between single-screen and dual-screen display modes without user intervention
Solution Approach 3:
The display apparatus performs self-service by automatically selecting the appropriate display mode based on its own detected state. The system serves itself by making intelligent decisions about display configuration without requiring external user commands
2Ease of operation
If the display apparatus automatically detects opening degree and inclination, then the ease of operation is improved, but the device complexity increases due to additional detecting units and control logic
Solution Approach 1:
The detected opening degree and inclination data serve multiple purposes: they trigger display mode changes, determine image orientation, and potentially inform other system behaviors. This multi-functionality justifies the added complexity by extracting maximum utility from the detection capabilities
Solution Approach 2:
The system monitors changes in physical parameters (opening degree and inclination) and responds by changing display parameters (display mode and image orientation). This parameter-based control approach provides a systematic framework that manages complexity through clear parameter relationships

AI summary
Provided is a foldable display apparatus that reduces inconvenience of an operation. Smartphone is a display apparatus including two screens respectively held by two casings that are connected rotatably about an axis. When an app is selected by selection unit in response to an operation for instructing startup of the app being performed by a user on operation unit, execution unit executes the app. Display control unit determines on which of the two screens an image of the app executed by execution unit is to be displayed based on an opening degree of the two casings detected by opening degree detecting unit and inclinations of the two casings relative to a vertical direction detected by inclination detecting unit, according to data stored in storage unit. Display unit displays the image of the app on either or both of the two screens in accordance with the determination of display control unit.
