Technical Field

The application relates to the field of visual images, in particular to a stereoscopic display screen.

Background

In a visual system, because the distance between two eyes of us is about 60mm, when we watch an object, the imaging of the object on the retina of the left eye and the retina of the right eye has a certain level difference, which is what we usually say is parallax (disparity/parallax), and even if there is the parallax, the brain of us can judge the distance of the object, that is, the 3D picture with the sense of depth and stereo can be seen.

3D graphics are displayed in a computer, namely three-dimensional graphics are displayed in a plane, and unlike the real world, a real three-dimensional space and a real distance space exist. In a computer, space sense is often required to be established through a 3D coordinate system as reference, and the characteristics of the near size and the far size of an object are matched with human eyes to form the three-dimensional effect of the object. As shown in the following figure (fig. 1), different vertex positions on the surface of an object are shielded by corresponding coordinate positions, so that a person establishes up-down left-right position information of each vertex in a corresponding 3D space in the brain, all the vertices on the surface of the object are shielded by the coordinate positions, and finally 3D stereo information relative to the coordinate space is formed in the brain, so that the person can predict the distance of the object in a picture, and can cheat the brain to generate a naked eye 3D effect, as shown in fig. 1.

Therefore, if a holographic 3D effect of an object is desired to be simulated in reality, a three-dimensional reference space needs to be established in the real space, and the three-dimensional content of the object is displayed in the three-dimensional reference space by using a transparent display technology. The existing transparent display technology has the problems of high cost, low definition, large volume and the like, for example, the transparent display scheme used by the existing holographic projection system comprises the most common transparent scheme for secondary imaging by utilizing 45-degree angle holographic glass reflection, but the scheme has the defects that the image is not clear due to serious light loss after secondary imaging and the influence of background light, the image is only used in a darker environment, and meanwhile, a projection source cannot be hidden; there are also solutions using a transparent liquid crystal panel plus a backlight or directly using a transparent OLED panel, because the transparent display requires a strong backlight driving, and thus has high power consumption and is expensive. The problem common to these several solutions is that the system is bulky; the sharpness is not as high as that of the conventional display screen due to the interference of the background light.

Disclosure of Invention

The design scheme can effectively reduce the volume of the whole display system, so that the volume is only half of the original volume, and the corresponding hardware consumption is reduced.

Further, the optical component is embedded in the surface of the space imaging frame component, arranged in the space imaging frame component or arranged outside the space imaging frame; the optical component embedded into the surface of the spatial imaging frame component comprises a light source arranged in the surface of the spatial imaging frame component and a structure which is arranged in the surface of the spatial imaging frame component and is freely transparent, wherein the transparent structure is an optical component which enables the light source to penetrate out of the surface of the spatial imaging frame component to the inner cavity of the spatial imaging frame component. At this time, the intensity of the optical signal projected by the optical component into the inner cavity of the imaging frame component is lower than that of the video information.

Further, when the optical component is disposed outside the imaging frame, it means that the optical component is formed by natural light; or the optical component being arranged outside the imaging frame means that the optical component is arranged outside the spatial imaging frame component.

Further, the transparent display component comprises a display screen and a half-transmitting and half-reflecting light ray component; the semi-transmitting and semi-reflecting light ray part is arranged between the space imaging frame part and the display screen and is attached to the surface of the display screen.

Further, when the display screen displays video information, the three optical signals are converged to enter human eyes to form images including a foreground stage imaging area image, a video content image and a virtual background stage imaging area image, wherein the foreground stage imaging area is close to the human eyes relative to the virtual background stage imaging area; the video information is positioned between the foreground stage imaging area and the virtual background stage imaging area; the foreground stage imaging area image, the video content image and the virtual background stage imaging area image form a stereoscopic view with a deep scene sense; the specific three optical signals refer to: 1) the optical signal of the video information enters the human eye through the mirror glass (semi-transparent semi-reflecting glass); 2) the light signal emitted by the foreground stage imaging area enters human eyes; 3) the optical signal of the virtual back scene stage imaging area formed by the reflection of the semi-transparent semi-reflecting glass in the foreground stage imaging area enters human eyes. This kind of design can abandon the use of traditional transparent screen, uses ordinary LCD screen (non-transparent screen) and semi-transparent semi-reflecting glass in the space that the space formation of image frame part built, also can realize virtual transparent effect, and this uses the cost of traditional transparent screen with greatly reduced, simultaneously because there is not the influence of background light to transparent screen, and the definition also promotes greatly.

Further, the video information is 3D video information or 2D video information with a black background.

Further, a closed component for viewing is arranged at the front end part of the space imaging frame component.
