Collaborative Display Region Segmentation for Reduced Relayout Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing collaborative display systems, when a terminal device's display state changes, such as from portrait to landscape mode, the display windows on a secondary device also change, leading to content being relaid out and refreshed, causing delays and affecting user experience.
Innovation Solution
A method where a first terminal device determines and sends display region information to a second terminal device, allowing it to display the home screen and virtual screen without needing to adjust the content display manner or relative location of the virtual screen, thus reducing the need for relayout and refresh.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display state of the first terminal device changes (e.g., from portrait to landscape mode), then the display window on the second terminal device also changes correspondingly, but this causes content to be relaid out and refreshed again, resulting in display delay
Solution Approach 1:
The patent segments the display system into two independent parts: the first terminal device's display state changes are separated from the second terminal device's content rendering. The second terminal device maintains its own display window configuration independently, receiving only updated content data without being forced to relayout the entire interface. This segmentation allows the first device to adapt its display state while the second device avoids unnecessary layout recalculations, reducing display delay.
Solution Approach 2:
The patent implements preliminary action by pre-establishing the display window configuration on the second terminal device before the first terminal device's display state changes. The display window's position, size, and layout are determined in advance and remain stable. When the first device changes its display state, only the content within the pre-configured window needs updating, not the window structure itself, thereby avoiding time-consuming relayout operations.
2Adaptability or versatility
If the display window on the second terminal device changes from portrait to landscape mode, then it can accommodate the changed display state, but this requires content to be laid out and refreshed again, affecting user experience
Solution Approach 1:
The patent separates the display adaptation function from the content display function. The second terminal device maintains a stable display window configuration that does not change with the first device's display state. Instead of changing the window's orientation and layout, only the content within the window is updated. This segmentation allows the system to support multiple display modes while avoiding repeated layout operations that would disrupt user experience.
3Reliability
If the content in each display window is relaid out and refreshed, then the display state can be updated, but this causes delay in displaying content on the second terminal device
Solution Approach 1:
The patent applies preliminary action by pre-determining the display window configuration on the second terminal device before any display state changes occur. The window's position, size, and layout structure are established in advance and remain fixed. When the first terminal device changes its display state, the system only needs to update the content data within the pre-configured window, not the window structure itself. This approach maintains reliable display state consistency while avoiding time-consuming relayout operations, thus improving content display efficiency.

AI summary
This application is applicable to the field of terminal technologies, and in particular, to a collaborative display method, a terminal device, and a computer-readable storage medium. In the method, a first display region of a home screen of a first terminal device in a second terminal device and a second display region of a virtual screen in the second terminal device may be determined, so that the second terminal device may display the home screen in the first display region and display the virtual screen in the second display region.
