Rollable Display Element Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices with rollable displays face challenges in dynamically adjusting the size and layout of screen elements as the display area changes with rotation, failing to optimize user experience across varying screen sizes.
Innovation Solution
An electronic device with a processor that senses the display area's size changes and adjusts the size and layout of screen elements accordingly, including increasing element sizes, changing layouts, and adding or removing elements based on priority orders and application types, to maintain an optimal user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display area size is changed by rolling or unrolling, then the screen can provide larger or smaller display areas, but the size and layout of screen elements cannot be dynamically adjusted
Solution Approach 1:
The patent implements dynamic adjustment of screen element sizes and layouts based on the current display area size. When the display is rolled or unrolled, the system automatically recalculates and repositions elements to maintain optimal visibility and usability, transforming the static interface into a dynamic one that adapts to changing physical conditions.
Solution Approach 2:
The system changes multiple parameters simultaneously including element size, element position, font size, and line spacing based on the display area size. This comprehensive parameter adjustment ensures that content remains readable and interactive elements remain accessible regardless of whether the display is in a compact rolled state or an expanded unrolled state.
2Area of stationary object
If the display area is increased by unrolling, then more content can be displayed, but the layout and readability of content may deteriorate
Solution Approach 1:
The layout system dynamically adjusts element positions, sizes, and spacing based on the current display area dimensions. This ensures that even when the display is unrolled to maximum size, content maintains proper formatting, margins, and readability rather than appearing distorted or improperly spaced.
Solution Approach 2:
Multiple layout parameters including element width, height, position coordinates, font size, and line spacing are simultaneously adjusted based on the display area size. This coordinated parameter change maintains content precision and readability across different display states.
3Area of stationary object
If the display area is decreased by rolling, then the device becomes more compact, but content readability and usability may be compromised
Solution Approach 1:
When the display is rolled to a smaller size, the system dynamically scales down element sizes and adjusts layouts to fit the reduced area while maintaining readability. Critical content elements are prioritized and preserved, ensuring that even in compact form, the display remains functional and readable.
Solution Approach 2:
The system adjusts multiple parameters including reducing element sizes, decreasing font sizes, and modifying line spacing to accommodate the smaller display area. These parameter changes are calculated to maintain content readability and usability despite the reduced physical dimensions.
4Device complexity
If fixed screen element sizes are used, then the interface is simple to implement, but it cannot adapt to different display area sizes
Solution Approach 1:
The interface transitions from static fixed-size elements to dynamic elements that automatically adjust their size and position based on display area measurements. This dynamic behavior enables the same interface to function effectively across the full range of display sizes from fully rolled to fully unrolled states.
Solution Approach 2:
The system implements parameter-driven element sizing where element dimensions, positions, and spacing are calculated based on the current display area size. This approach provides adaptability without requiring multiple separate interface designs for different display states.
