Screen Projection Display Sync for Immersive Multi-Device Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection technologies fail to synchronize immersive display effects between a projecting device and a projected device, resulting in non-immersive display on the projected device when content is shared from a mobile phone to a larger screen like a tablet computer.
Innovation Solution
A method that enables immersive display synchronization by adjusting the display settings of the projecting device to match the projected device, hiding or showing status and navigation bars based on collected status data, allowing the projected device to display content without these bars in an immersive manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile phone displays UI content with status bar and navigation bar hidden to implement immersive display effect, then the immersive display effect on the mobile phone side is improved, but the immersive display effect on the tablet computer side deteriorates because the projected content includes status bar, navigation bar, and title bar
Solution Approach 1:
The patent implements feedback by having the projecting device send status information about its display state (whether status bar and navigation bar are hidden) to the projected device. The projected device receives this feedback and adjusts its own display state accordingly, ensuring both devices maintain consistent immersive display effects during screen projection
Solution Approach 2:
The patent changes the display parameters of the projected device based on the source device's state. When the source device hides its status bar and navigation bar, the projected device also modifies its display parameters to hide corresponding elements, achieving parameter synchronization between the two devices for consistent immersive display
2Area of stationary object
If the mobile phone projects screen content to the tablet computer, then the screen size advantage is improved, but the display effect synchronization between devices deteriorates due to presence of status bar, navigation bar, and title bar on projected content
Solution Approach 1:
The patent segments the display content into different elements (main content area, status bar, navigation bar, title bar) and applies different processing rules to each. The main content is projected to utilize the larger screen area, while the status bar and navigation bar are selectively hidden on the projected device to maintain display quality, achieving both large screen advantage and good display effect

AI summary
This application provides a projection display method and an electronic device, and relates to the field of communication technologies, to implement immersive display effect synchronization between a projecting device and a projected device in a projection scenario. A specific solution includes: A first electronic device displays a first interface including first content, where the first interface further includes a status bar and/or a navigation bar of the first electronic device. A second electronic device displays a first projection window including the first content, where the first projection window further includes any one of the status bar, the navigation bar, and a title bar of a projection application. The first electronic device switches from displaying the first interface to displaying a second interface, where the second interface includes second content, and the second interface does not include the status bar and the navigation bar. The second electronic device switches from displaying the first projection window to displaying a second projection window, where the second projection window includes the second content, and the second projection window does not include the status bar, the navigation bar, and the title bar.
