Foldable Display Screen Segmentation for Input Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display devices face challenges in operational convenience and input accuracy due to the complexity of user interactions on multiple screens, particularly when transitioning between unfolded and folded states.
Innovation Solution
A foldable display device design that divides the screen into two areas, where one screen senses user input and the other displays an image, allowing a cursor to be generated on the second screen corresponding to the user's touch point on the first screen, thereby reducing unnecessary operations and enhancing input accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the screen is divided into two areas with one for sensing and one for displaying, then input accuracy is improved, but device complexity increases
Solution Approach 1:
The display screen is segmented into two functional areas: a first area for sensing user input and a second area for displaying images. This segmentation allows the system to process input coordinates from the first area and map them to corresponding positions on the second area, thereby improving input accuracy without requiring a completely separate input device.
Solution Approach 2:
The first screen area serves dual purposes: it functions as both a display area and an input sensing area. By making the screen multi-functional, the system avoids adding separate hardware components, thus improving input accuracy while minimizing the increase in device complexity.
2Ease of operation
If a cursor is generated on the second screen corresponding to the user's touch point on the first screen, then operational convenience is improved, but processing time increases
Solution Approach 1:
The system pre-establishes a coordinate mapping relationship between the first screen area and the second screen area. When the user touches the first screen, the system immediately calculates the corresponding position on the second screen and generates the cursor there, eliminating the need for real-time complex calculations and improving operational convenience with minimal processing delay.
Solution Approach 2:
The system provides immediate visual feedback by generating a cursor on the second screen at the position corresponding to the user's touch on the first screen. This feedback mechanism enhances operational convenience by clearly indicating where the user's input will affect the display, while the pre-established coordinate mapping ensures this feedback is generated quickly with minimal processing time.

AI summary
A foldable display device includes a screen maintained in one of a folded state and an unfolded state, the screen, when switched from the unfolded state to the folded state, being divided into a first screen sensing a user input and a second screen displaying a first image, and a controller displaying a specific image corresponding to the user input on the second screen when the user input is sensed on the first screen in the folded state. The first screen displays a second image that is the same as the first image.
