Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Displaying a two-dimensional code on an electronic device interrupts the current task and requires multiple operation steps, affecting user experience.
Innovation Solution
A method for displaying a two-dimensional code on a secondary screen of an outward foldable electronic device, allowing the primary screen to continue its task without interruption, and ensuring secure and timely display management based on the device's state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a two-dimensional code is displayed on the main screen, then the code is visible to the user, but the current task is interrupted and multiple operation steps are required
Solution Approach 1:
The display screen is divided into two independent display regions: a first display region (main screen) for displaying the current task and a second display region (secondary screen) for displaying the two-dimensional code. This segmentation allows both functions to operate simultaneously without interfering with each other, eliminating task interruption and reducing operation steps.
Solution Approach 2:
The patent introduces a spatial dimension by utilizing the back surface of the device as a second display region. When the device is held in a folded state, the first display region faces forward for the main task while the second display region faces backward for the two-dimensional code, effectively adding a spatial dimension to the display architecture.
2Productivity
If the two-dimensional code is displayed on the secondary screen, then the main task continues without interruption, but the code may be accidentally displayed when the screen is locked or off
Solution Approach 1:
The system dynamically adjusts the display behavior of the secondary screen based on the state of the first display region. When the first display region is in a locked or turned-off state, the secondary screen automatically suppresses the two-dimensional code display. This dynamic control ensures that the code is only displayed when the main task is active and accessible, preventing accidental display while maintaining task continuity.
3Adaptability or versatility
If the display screen is in a folded state with opposite display directions, then the device is portable, but the secondary screen display may not be visible to the user
Solution Approach 1:
When the device is in a folded state, the patent inverts the traditional display arrangement by placing the two-dimensional code on the back-facing second display region rather than the front-facing first display region. This inversion allows the code to be displayed on the surface that is actually visible to the user when holding the device folded, ensuring code visibility while maintaining portability.

AI summary
This disclosure 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. 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.
