Description

Naked eye 3D transparent screen structure

Technical Field

The utility model belongs to bore hole 3D transparent screen field especially relates to a bore hole 3D's transparent screen structure.

Background

From the appearance of the transparent screen to the present common use, a plurality of development stages are experienced, the size of the liquid crystal display panel is larger and more, additional functions are added, and in addition, various application software is added, the use of the transparent screen is already applied to clothes, catering, commercial advertisements and exhibition and display. Along with the advertising promotion means, the transparent screen is more and more diversified, and the transparent screen is more and more widely applied in the aspects of advertising release, product display, information promotion (acquisition) and the like.

The most basic principle of the transparent screen is to enlarge the structure based on the conventional liquid crystal display screen, and to increase the distance between the liquid crystal display panel and the backlight system from a very small distance (generally 2-3 mm) to 200mm or more. By increasing this distance a physical cavity is formed between the display panel and the backlighting system, so that items, typically cosmetics, art work, jewelry diamonds, etc., can be placed in this space area for display. The transparent screen backlight system is similar to the conventional liquid crystal display screen, and comprises a lamp panel (lamp strip), a diffusion plate and an optical diaphragm. Because the whole structure is larger, a sheet metal part or an aluminum profile is usually used as a main body structure, and then an aluminum plastic plate or PMMA and other light materials are matched to form a complete structure. The exterior can be designed with various shapes and colors according to the needs, and the inner cavity can be made of metal plate powder spraying or white plastics and other materials with high light reflection rate so as to improve the utilization rate of the light source system.

Common transparent screens are for example street-side platform advertising displays, vending machines in parking lots, stations, airports, display windows in clothing stores, etc.

The display panel part in the current transparent screen adopts the conventional 2D display technology: the LCD comprises a common 2D LCD screen and a common 2D film source, wherein in order to enable a 2D display panel and a transparent screen of the 2D display film source to realize a 3D display effect, a manufacturer designs the transparent screen to form a structural cavity by increasing the distance between a backlight system and the LCD screen on the basis of the common LCD screen, the length and width of the cavity are generally larger than the display size of the LCD screen, and then the 3D effect is generated due to the structural cavity and the poor vision of a reference object; and thirdly, adding visual effect means such as the depth of field, scene change and the like of the picture in the 2D film source production through a film source production means, and enhancing the 3D effect to a certain extent.

However, only by means of structural design and a mode of adjusting visual effects of a 2D film source, the effect that a picture represented by a transparent screen can achieve in the 3D visual effects such as a 3D display distance and a depth of field is limited, and therefore a perfect 3D display effect cannot be really achieved. Other enterprises in the industry adopt various technical means to integrate the 3D display technology and the transparent screen, but the display part is still a 2D liquid crystal screen all the time, and is not a true 3D display screen. How to use bore hole 3D display technology in transparent screen, better embody the 3D formation of image effect of transparent screen for transparent screen can be in the important means that shows that the field better develops.
