VR Multi-Screen Display Layout Without Picture Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality (VR) glasses systems shield part of the picture when displaying multiple applications due to screen size limitations, affecting user experience and requiring a screen-off state to save power.
Innovation Solution
A VR multi-screen display method that draws content of multiple active applications to different positions on a virtual display of VR glasses, using a processor to manage virtual screens and implement a distortion algorithm for enhanced viewing without shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate display devices are used to achieve multi-screen display, then display flexibility and functionality are improved, but device complexity and port occupation are increased
Solution Approach 1:
The display interface is segmented into multiple virtual display areas (first display area, second display area, third display area) within a single physical display device. Each virtual area can independently display different content types (notification messages, media players, etc.), achieving multi-screen functionality through software partitioning rather than multiple physical devices.
Solution Approach 2:
A single display device is designed to perform multiple functions by dividing its display area into different functional zones. The same physical screen can simultaneously serve as a notification display, media player, and other applications, making the device universal and eliminating the need for multiple specialized devices.
2Adaptability or versatility
If multiple separate display devices are used to achieve multi-screen display, then display flexibility and functionality are improved, but occupation of ports is increased
Solution Approach 1:
Multiple display functions that would traditionally require separate physical devices are merged into a single display device. The notification display, media player, and other applications are combined in one screen, reducing the number of physical devices needed and thereby reducing port occupation.
Solution Approach 2:
The display device is designed with multi-functionality, allowing it to handle various display tasks (notifications, media playback, etc.) simultaneously through different virtual areas, eliminating the need for multiple specialized devices and reducing port requirements.
3Loss of information
If notification messages are displayed by popping up on the whole screen, then user awareness is improved, but available display area for other content is reduced
Solution Approach 1:
The notification display is localized to a specific area (first display area) rather than occupying the entire screen. This allows notifications to be displayed in a designated zone while other areas of the screen remain available for primary content display, maintaining both user awareness and display area efficiency.
Solution Approach 2:
The screen is segmented into multiple functional areas, with the notification area being just one segment. This segmentation allows notifications to be displayed without blocking the entire screen, as other segments can simultaneously display media content and other applications.

AI summary
This application provides a VR multi-screen display method and an electronic device. The method includes: An electronic device receives a first operation performed by a user in an application that supports VR; and the electronic device starts a VR multi-screen display mode in response to the first operation. Then, the electronic device receives a second operation performed by the user on a first application icon, and receives a third operation performed by the user on a second application icon; separately creates a first virtual screen corresponding to a first application and a second virtual screen corresponding to a second application in response to the second operation and the third operation; and displays content of the first application on the first virtual screen, and displays content of the second application on the second virtual screen. According to the method, content of a plurality of applications that are in an active state in the electronic device can be respectively drawn to different positions of a virtual display picture of a pair of virtual reality glasses, to achieve a multi-screen display effect without shielding the picture.
