Flexible Display Page Direction Control via Input Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable devices with flexible displays lack an effective method to control the display direction of additional pages when the display is expanded, leading to discontinuity in information presentation and user confusion regarding the sequence of pages.
Innovation Solution
A portable device and control method that allow the display direction of pages to be controlled by user input signals, providing indicators for the display direction and sequence, ensuring continuity and clarity in displaying additional pages in an expanded flexible display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a flexible display is expanded to provide additional display area, then the display area is increased, but the control method for maintaining continuity and clarity of information presentation becomes complex
Solution Approach 1:
The patent applies dynamics by making the display configuration adaptable and changeable. The flexible display can be expanded or retracted based on user needs, and the control method dynamically adjusts the display direction and sequence of additional pages according to the expansion state and user input signals, rather than using a fixed control scheme
Solution Approach 2:
The patent segments the display content into additional pages that are selectively displayed based on expansion state. The display area is divided into the main display region and additional display regions, with each region presenting information in a coordinated manner to maintain overall continuity and clarity
2Loss of information
If additional pages are displayed in expanded flexible display area, then information presentation is enhanced, but user confusion regarding sequence and direction occurs without proper control
Solution Approach 1:
The patent implements feedback by detecting user input signals (such as touch gestures or button presses) and using these signals to control the display direction and sequence of additional pages. The system provides visual feedback through indicators that show users which pages are displayed and in what order, allowing users to understand and control the information flow
Solution Approach 2:
The patent applies preliminary action by providing indicators that预先 indicate the display direction and sequence of additional pages before users interact with them. This allows users to understand the information structure in advance and navigate the expanded display content more effectively
3Device complexity
If display direction of additional pages is not controlled by user input, then system operation is simplified, but user experience and control precision deteriorate
Solution Approach 1:
The patent applies self-service by enabling users to control the display direction and sequence themselves through intuitive input signals. The system provides the tools and interface for users to manage their own information presentation, rather than relying on complex automated control or fixed display patterns

AI summary
A portable device and a control method thereof are disclosed, in which a user may control a display of the device more conveniently and exactly. The portable device comprises a main display; a flexible display; a sensor unit configured to sense at least one of expanding of the flexible display and an input signal; and a processor configured to control the main display, the flexible display and the sensor unit, when a first page of a plurality of pages having a sequence is being displayed in the main display, wherein the processor is further configured to : display an indicator in the main display when the input signal is sensed, the indicator indicating a display direction of additional pages to be displayed when the flexible display is expanded, wherein the indicator further indicates a forward direction or a reverse direction on a basis of the first page as the display direction, and display at least one additional page in the display direction indicated by the indicator in the main display and the flexible display when the expanding of the flexible display is sensed.
