Foldable Display Side Screen Touch Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to effectively utilize the side screen of a foldable mobile phone when it is in a folded state, enhancing user experience by allowing control of the primary and secondary screens through the side screen.
Innovation Solution
A touch method is implemented on an electronic device with a foldable display, where the side screen functions as a touch area, allowing users to control the primary and secondary screens by mapping touch functions of these screens to the side screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the foldable mobile phone is folded, then the device can be carried conveniently, but the side screen cannot be properly utilized
Solution Approach 1:
The side screen is transformed from a non-functional or limited-functional area to a multi-functional control interface. By mapping touch functions of the primary and secondary screens to the side screen, the patent enables the side screen to serve multiple purposes including navigation, media control, and system operations, thereby resolving the contradiction between device portability and side screen utilization.
Solution Approach 2:
The side screen acts as an intermediary control interface between the user and the main display screens. By mapping touch functions to the side screen, users can control the primary and secondary screens without directly interacting with them, providing a convenient control mechanism when the device is folded and the main screens are not easily accessible.
2Ease of operation
If touch functions are mapped to the side screen, then user control is facilitated, but the system complexity increases
Solution Approach 1:
The patent implements touch function mapping by creating virtual representations of touchable areas from the primary and secondary screens on the side screen. Instead of implementing complex new control mechanisms, the system copies the existing touch interface elements and redistributes them to the side screen area, simplifying the implementation while enhancing user convenience.
Solution Approach 2:
The touch function mapping is dynamically adjusted based on the device's folding state and the user's holding position. The system detects the folded state and automatically maps appropriate touch functions to the side screen, adapting the interface configuration to the current usage scenario without requiring manual setup or complex configuration options.

AI summary
A method may be applied to an electronic device configured with a foldable display. The display includes a first area, a second area, and a third area, and when the electronic device is in a folded form, an included angle between the first area and the third area is less than a first preset angle, and two sides of a third area are the first area and the second area. The method includes: displaying a first interface in the first area, where the first interface includes one or more touchable areas; determining a first touch area between a user and the third area; mapping a touch function of a first touchable area in the first interface to the first touch area; detecting a first operation in the first touch area; and controlling the first touchable area in the first interface based on the first operation.
