Flexible Display Area Adaptation via Start Point Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communication terminals lose current search information when the screen is rotated 90°, requiring users to re-search for previously viewed areas after a screen aspect ratio change during detailed image searches.
Innovation Solution
A flexible display device and method that computes and maintains the start point of a changed display area based on its center point and size information, allowing the display area to adapt to aspect ratio changes without initializing search information, using a memory to store image data and size information, and a location computing unit to calculate the start point for the display unit to decode and display the corresponding image data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screen is rotated 90° to change aspect ratio, then the display area can be adjusted to fit different image sizes, but the current search information is lost and requires re-initialization
Solution Approach 1:
The patent calculates and stores the start point coordinates before screen rotation occurs. When rotation is detected, the pre-calculated start point is reused to maintain the display area's position relative to the original image, thereby preserving search information without requiring re-initialization.
Solution Approach 2:
The patent introduces a coordinate transformation mechanism that acts as an intermediary between the original display configuration and the rotated display configuration. This intermediary calculates the relationship between old and new coordinate systems, enabling seamless transition while maintaining search context.
2Area of stationary object
If the display area is enlarged to show more image detail, then the user can see more content, but the user cannot recognize contents precisely due to reduced zoom level
Solution Approach 1:
The patent dynamically adjusts the display area size and position based on user interaction. When users engage in detailed search, the system enlarges the display area to show more content. When users need precise recognition, the system can adjust the zoom level and reposition the display area to highlight specific regions, providing both comprehensive viewing and detailed examination capabilities.

AI summary
A display device to change an image displayed in a display area when the display area is changed includes a memory, a location output unit and a screen display unit. The memory stores size information of a display area displayed on a screen and the image data of the displayed image. The location computing unit computes a start point of the changed display area when the display area is changed. The display unit decodes data corresponding to the size of the display area based on the computed new start point from the image data to display the decoded data in the display area. Since the start point is obtained with center point of the changed display area and its size information and then a display area to be displayed is determined based on the start point, a current search location is maintained even when the screen is swung.
