Foldable QR Code Display for Uninterrupted Dual-Screen Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Displaying a two-dimensional code on an electronic device interrupts the currently performed task, requiring multiple operation steps and affecting user experience.
Innovation Solution
A method for displaying a two-dimensional code on a foldable electronic device with opposite display directions on its screens, allowing the code to be shown on a secondary screen without interrupting the primary task, and ensuring it is not displayed when the device is locked or in an unfolded state to protect user information and enhance user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a two-dimensional code is displayed on the display screen, then the code can be shown to the user, but the currently performed task is interrupted and multiple operation steps are required
Solution Approach 1:
The patent utilizes the foldable screen's second screen (inner screen) to display the two-dimensional code, effectively adding a spatial dimension for code display. This allows the code to be shown on a different physical surface without interrupting the primary task displayed on the first screen (outer screen), thereby reducing operation steps and time loss.
Solution Approach 2:
The display screen is segmented into two independent display regions (first screen and second screen) that can function simultaneously. The first screen continues displaying the primary task while the second screen displays the two-dimensional code, allowing parallel operation and eliminating the need to interrupt the current task.
2Area of stationary object
If the display screen is in unfolded state, then the device provides a large display area, but displaying code would interfere with the user's current task
Solution Approach 1:
The system dynamically adjusts which screen displays the two-dimensional code based on the display screen's physical state. When folded, the code appears on the second screen; when unfolded, the code is not displayed on either screen to avoid interfering with the user's current task. This dynamic adaptation resolves the contradiction between display area and task continuity.
3Reliability
If the display screen is in locked state, then user information is protected, but the user cannot access the two-dimensional code
Solution Approach 1:
The system checks the lock state before allowing code display. When the display screen is locked, the code is not displayed on the second screen, preventing unauthorized access. When unlocked, the code can be displayed. This preliminary state check ensures information security is maintained while allowing code accessibility when appropriate.

AI summary
This application provides a two-dimensional code display method and a related electronic device. The electronic device includes a display screen. The display screen includes a first screen and a second screen. Display directions of the first screen and the second screen are opposite to each other when the display screen is in a folded state. The display directions of the first screen and the second screen are the same when the display screen is in an unfolded state. When the display screen is in the folded state, a first user interface including an interface of a first application is displayed on the first screen; a first operation is received at a first time point, and a first two-dimensional code of a second application is displayed on the second screen in response to the first operation; the first user interface is displayed on the first screen in a process of displaying the first two-dimensional code on the second screen; and the second screen is turned off after the first two-dimensional code is scanned. When the display screen is in the unfolded state, a second user interface of the first application is displayed on the display screen; and the first operation is received at a second time point, and the first two-dimensional code of the second application is not displayed on the second screen. This application can improve user experience.
