Flexible Display Application Window Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with flexible displays struggle to effectively manage the display and control of multiple applications based on user intent, particularly in rollable displays where the screen length can vary, leading to challenges in determining which applications to display and their size.
Innovation Solution
A display device comprising a main display, a flexible sub-display, a measurement unit, and a controller that allows users to set and control the display of multiple applications based on user input, application attributes, and screen length, enabling dynamic adjustment of application sizes and positions on the flexible sub-display.

Engineering Contradiction Analysis
1Area of stationary object
If a flexible display is rolled in a rollable display to provide a larger display while maintaining portability, then the display area is increased, but it becomes difficult to determine which applications to display and their size when the screen length varies
Solution Approach 1:
The system dynamically adjusts the number and size of application windows based on the current unfolded length of the flexible display. When the display is extended, more applications can be shown with larger window sizes, and when retracted, the system automatically reduces the number of visible applications or their sizes to fit the available screen real estate.
Solution Approach 2:
The display device changes the parameter of screen length through the flexible display mechanism, and the controller相应ly adjusts application display parameters (number of windows, size of each window) based on the measured flexible display length, creating a coordinated parameter adaptation system.
2Loss of information
If the rollable display is extended to show multiple applications, then application visibility is improved, but screen real estate optimization becomes challenging
Solution Approach 1:
The system employs dynamic window management where the number and dimensions of application windows are not fixed but adapt in real-time based on the flexible display's current length, allowing optimal utilization of available screen space while maintaining visibility of multiple applications.
Solution Approach 2:
The measurement unit continuously monitors the flexible display length and provides feedback to the controller, which then adjusts the application display configuration accordingly, creating a closed-loop system that optimizes screen real estate utilization based on actual physical state.

AI summary
Disclosed are a display device for displaying multiple applications on a flexible display and a method for controlling the display device. The display device according to the present specification comprises a main display and a flexible display. When the flexible display is unrolled, the size of a first application execution screen is determined by the unrolled length. When the flexible display is further unrolled thereafter, a second application execution screen is displayed along with the first application execution screen on the flexible display. Here, the second application execution screen is displayed on the portion by which the flexible display has been increased and can be displayed on the part adjacent to the first application execution screen. According to the present specification, the size of an application execution screen can be determined according to the intent of a user.
