Foldable Back-Screen QR Display With Main-Screen Fallback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The utilization of the back screen in foldable-screen devices is low due to users not paying attention to it when in a folded state, leading to an idle state.
Innovation Solution
A method for displaying two-dimensional codes on the back screen of foldable-screen devices by enabling a two-dimensional code function upon user interaction, allowing quick access and utilization without flipping the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the back screen is used to display two-dimensional codes in folded state, then the utilization of back screen is improved, but the user may not notice the display on the back screen since it faces away from the user
Solution Approach 1:
The system provides feedback by detecting tap operations on the back screen and responding by displaying two-dimensional codes. This feedback mechanism ensures that the back screen serves its intended function while providing visible confirmation to the user through the tap interaction, resolving the contradiction between utilizing the back screen and ensuring user awareness.
Solution Approach 2:
The back screen performs self-service by automatically displaying the appropriate two-dimensional code when tapped, without requiring the user to manually navigate through applications or settings. This self-service capability improves back screen utilization while maintaining user awareness through the direct tap-display relationship.
2Speed
If the two-dimensional code function is always enabled on the back screen, then the scanning speed is improved, but the energy consumption and system complexity increase
Solution Approach 1:
Instead of continuously enabling the two-dimensional code function, the system uses periodic activation triggered by tap operations. The code display function is activated only when needed (upon tapping) and can be deactivated afterward, reducing energy consumption while maintaining fast scanning capability when required.
Solution Approach 2:
The two-dimensional code function transitions from a static always-on state to a dynamic on-demand state. The system adaptively enables or disables the code display based on user interaction, optimizing the balance between scanning speed and energy consumption by activating the function only when actually needed.

AI summary
Embodiments of this application provide a two-dimensional code display method, an electronic device, a chip, and a storage medium, and relate to the field of terminal technologies. When the electronic device is in a folded state, if an operation of triggering display of a two-dimensional code on a back screen is received, a screenshot of a payment application is obtained, and whether the screenshot of the payment application includes a two-dimensional code is monitored. If the two-dimensional code is not displayed, a two-dimensional code display task on the back screen is moved to the main screen, and an interface of the payment application is displayed on the main screen. In this way, a user can find that the back screen fails to display the two-dimensional code without a need to flip the screen, triggers display of the two-dimensional code on the main screen through an operation on the interface of the payment application on the main screen, such as an operation of authorizing the application to enable a payment code, an operation of determining to open a two-dimensional code interface, and an operation of entering an unlock password of the application, and uses the two-dimensional code for scanning, thereby improving user experience.
