Screen Projection Orientation Lock During Display Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen projection methods result in inconsistent and inconvenient display modes on external devices due to mirroring projection, leading to a suboptimal user experience.
Innovation Solution
A method and device for screen projection that allows the application interface to be displayed in a predetermined region of the first mode and subjected to screen projection, the application interface is kept displayed in the first mode and subjected to screen projection, the application interface of the target application is kept displayed in the first mode in a predetermined region of the first screen, and the projection data is transmitted to the second screen, maintaining the first mode even when the display mode of the first screen changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If mirroring projection is used to project all contents from the first screen to the second screen, then the display content consistency between screens is improved, but the user experience deteriorates due to inconvenient operation and inability to switch display modes
Solution Approach 1:
The patent segments the display content into two independent parts: the projected application interface on the second screen maintains its original orientation, while the first screen can independently switch to a different display mode. This segmentation allows each screen to serve different functions simultaneously, resolving the contradiction between content consistency and operational flexibility.
Solution Approach 2:
The patent implements dynamic display mode switching where the first screen can change its orientation mode independently during projection. The system dynamically adjusts the display modes of both screens based on user needs, allowing the first screen to switch between portrait and landscape modes while the projected content maintains stability, thus improving both operational convenience and content stability.
2Adaptability or versatility
If the display mode of the first screen is switched during projection, then the adaptability to different usage scenarios is improved, but the display mode stability on the second screen deteriorates
Solution Approach 1:
The patent separates the display mode control of the two screens, allowing independent mode selection. The first screen's display mode can be switched to adapt to different usage scenarios, while the second screen's projected content maintains its original display mode, achieving both adaptability and stability simultaneously.
Solution Approach 2:
The patent applies different display mode qualities to different screens: the first screen uses dynamic mode switching to adapt to local usage needs, while the second screen maintains a fixed display mode for stable projection. This local quality differentiation resolves the contradiction between adaptability and stability.
3Area of stationary object
If the application interface is displayed in full screen mode on the first screen, then the display area is maximized, but the ability to concurrently use other display pages deteriorates
Solution Approach 1:
The patent implements dynamic switching between full-screen mode and floating window mode for the projected application interface. Users can switch between these modes to balance display area and concurrent usage needs, allowing the system to adapt to different usage scenarios and resolve the contradiction between maximizing display area and enabling concurrent operations.

AI summary
Provided are a method and device for screen projection, a terminal and a storage medium. After a target application is set to be displayed in a first mode and subjected to screen projection, the method includes that: after a display mode of a first screen is switched from the first mode to a second mode, an application interface of the target application is kept displayed in the first mode, the second mode being a portrait mode in response to that the first mode is a landscape mode, or, the second mode being a landscape mode in response to that the first mode is a portrait mode; projection data of the target application is acquired; and the projection data is transmitted to a second screen to which the screen projection is directed to.
