Rollable Display Control for Full Content During Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible displays take time to fully extend, causing viewers to miss content details and limiting utilization of the extended display area.
Innovation Solution
A display apparatus with a control unit that maintains image ratio and adjusts image size to ensure the entire content is displayed as the display extends, allowing additional functions on the extended area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display is extended from the housing, then the display area is increased, but the content cannot be fully displayed during the extension process
Solution Approach 1:
The display apparatus dynamically adjusts the image size and position based on the real-time extension state of the flexible display. During extension, the control unit continuously modifies the displayed content parameters to ensure the entire content remains visible, transitioning from a static display approach to a dynamic adaptation approach.
Solution Approach 2:
The control unit changes the image parameters (size, position, scaling) according to the extension length of the display. As the display extends, the system adjusts these parameters to maintain full content visibility, utilizing parameter transformation to resolve the contradiction between area expansion and information preservation.
2Area of stationary object
If the image size is increased to fill the extended display area, then the display coverage is improved, but the image ratio is distorted
Solution Approach 1:
The control unit dynamically adjusts image parameters including size, position, and scaling based on the extension state. This allows the system to optimize both display coverage and image ratio by transforming parameters in real-time rather than using a fixed display mode.
3Speed
If the display extension time is reduced, then the responsiveness is improved, but the content detail visibility is compromised
Solution Approach 1:
The control unit prepares and adjusts the image parameters in advance based on the predicted extension state. By performing preliminary adjustments as the display begins to extend, the system ensures content visibility is maintained throughout the extension process without requiring slower extension speeds.
4Loss of information
If the entire display area is used for content, then the content visibility is improved, but the additional functions cannot be accessed
Solution Approach 1:
The display area is divided into different functional zones with different qualities. The content is displayed in one area while additional functions (menus, controls, information) are provided in another area. This local differentiation allows both content visibility and functional accessibility to coexist by assigning different purposes to different parts of the display.
Solution Approach 2:
The flexible display is segmented into multiple functional regions during extension. The control unit manages different areas for different purposes: content display area and function access area. This segmentation resolves the contradiction by allowing simultaneous content visibility and function accessibility in separate zones.

AI summary
The present disclosure relates to a display apparatus allowing content to be recognized even when a display of a rollable display is not extended to the max-imum, the display apparatus comprising: a display; a housing; a roller accommodat-ed in the housing and rotating to wind or unwind the display; a display extending from the housing or retracting into the housing according to the rotation of the roller; and a control unit for controlling the display to display entire content on an extended region out of the housing while the display is being extended from the housing.
