Solution Overview
Problem
Conventional substantive screens occupy physical space, making them unsuitable for office and family use, and existing virtual 3D image displaying technologies also require substantial space or mediums.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a substantive screen is used for displaying images, then image display quality is improved, but occupied space increases
Solution Approach 1:
The patent uses a projection system to create a virtual image copy of the display content in space, eliminating the need for a physical screen. The projector displays images through optical projection, forming a visible virtual screen that occupies no physical space while maintaining full display functionality.
Solution Approach 2:
The patent replaces the mechanical physical screen with an optical field-based virtual screen. Instead of using a tangible display surface that occupies space, the system uses projected light fields to create a visible display plane that can be interacted with but occupies no physical volume.
2Area of stationary object
If a front-projection projector with projection board is used, then space occupancy is reduced, but the projection board physically occupies space in front of the user
Solution Approach 1:
The system projects a virtual image of the desktop interface into the air space above the actual desktop, creating a copy of the workspace that can be viewed and interacted with optically without blocking the physical desktop surface below.
Solution Approach 2:
The patent transitions the display from a 2D physical screen or projection board to a 3D virtual image space. The virtual screen exists in the spatial dimension above the desktop, allowing users to view and interact with content without the projection board occupying the horizontal desktop area.
3Area of stationary object
If a rear-projection screen or television is used, then horizontal space is saved, but vertical wall space is occupied
Solution Approach 1:
The patent replaces wall-mounted physical displays with a portable projection system that creates a virtual image in free space. The projector can be positioned on the desktop and projects upward, eliminating the need for vertical wall mounting and associated space occupation.
4Volume of stationary object
If 3D image displaying technologies using vapor or micro-particles are used, then virtual display is achieved, but substantial space or medium is required
Solution Approach 1:
The system creates a virtual image copy using optical projection onto a transparent or translucent surface, eliminating the need for vapor generation or micro-particle ejection. The virtual screen is formed by light refraction and reflection through the optical lens system without requiring substantial physical media.
Solution Approach 2:
The patent uses a transparent or translucent panel (such as a glass or plastic sheet) as the medium for projecting the virtual image. This thin film approach creates a visible display surface without requiring the substantial volume of vapor or particle-based 3D display systems.

AI summary
A touch control virtual screen apparatus is provided. The touch control virtual screen apparatus includes a screen, an optical structure, and a detection module. The screen is adapted for emitting light. The optical structure includes at least one optical lens, and is adapted for configuring an image of a virtual screen in a space corresponding to a screen image, in accordance with the optical imaging principle. The detection module is adapted for detecting whether a user touches the image of the virtual screen, and detecting a signal corresponding to a position of the virtual screen being touched, and converting the signal into the position and a related instruction corresponding to the position. In such a way, the user is allowed to operate digital content displayed on a virtual screen in a touch control manner, without directly touching the screen.
