Detachable 3D auto-stereoscopic display deviceTechnical Field
The utility model relates to a stereoscopic image display technique especially relates to a detachable 3D auto-stereoscopic display device.
Background
The 3D autostereoscopic display technique is to generate a frame of left-eye image seen by the left eye of an observer and a frame of right-eye image seen by the right eye of the observer on a display device, that is, to generate a binocular parallax image. The observer sees a three-dimensional image by observing the left-eye image and the right-eye image provided by the autostereoscopic display apparatus via the retinas of the left and right eyes. This 3D autostereoscopic display technique without glasses is also called a parallax barrier display technique. Generally, a 3D autostereoscopic display apparatus having a grating film assembly is added in front of a general liquid crystal flat panel display device, and the grating film assembly is spaced apart from the liquid crystal display device by a certain distance, so that a viewer can generate a binocular parallax image at a proper position in front of the liquid crystal flat panel display device. The parallax image can show a vivid, lifelike and immersive three-dimensional picture in front of a human body through the processing and adjustment of the binocular retina images of the human body. In the past, the 3D free three-dimensional display device is designed on the front shell or directly designed together with the front shell, cannot be freely disassembled, cannot be assembled when a user wants to use and cannot be taken down when the user does not use, and the flexibility and the maneuverability are poor.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a detachable 3D auto-stereoscopic display device.
The embodiment of the utility model provides a what realize like this, a detachable 3D freedom three-dimensional display device installs on liquid crystal flat panel display equipment, including metal grating membrane module and switching support; the switching support is fixed on the rear shell of the liquid crystal flat panel display device, and the metal grating membrane assembly is arranged at the corresponding position of the display screen of the liquid crystal flat panel display device and is fixed through the switching support.
The metal grating membrane assembly comprises a metal shell, a toughened glass grating membrane assembly and a liquid crystal panel distance limiting piece; the toughened glass grating film assembly and the liquid crystal panel distance limiting piece are respectively fixed on the metal shell.
The toughened glass grating film assembly and the liquid crystal panel distance limiting piece are fixed on the metal shell through the limiting piece, the fastening piece and the double faced adhesive tape.
The switching support comprises an upper switching support and a left switching support and a right switching support, and the upper switching support and the left switching support are respectively fixed on the rear shell of the liquid crystal flat panel display device.
Compared with the prior art, the embodiment of the utility model, beneficial effect lies in: the utility model discloses a 3D free three-dimensional display device adopts the design of detachable mode, and the user just assembles on the liquid crystal flat panel display equipment when wanting to use, just can take off when not using, and nimble mobility is fine, and has advantages such as simple structure, simple installation, preparation low cost.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the 3D autostereoscopic display apparatus in this embodiment mainly includes: the liquid crystal display panel comprises a metalouter frame 11, a toughened glassgrating membrane assembly 12, a liquid crystal paneldistance limiting piece 13, aleft switching bracket 21, aright switching bracket 21 and anupper switching bracket 22; wherein,
the tempered glassgrating film assembly 12 and the liquid crystal panel spacing limitingpiece 13 are fixed on the metalouter frame 12 through a limiting piece, a fastening piece and a double-sided adhesive tape, and are combined to form the metal grating film assembly 1, as shown in fig. 2;
the left andright adapter brackets 21 and theupper adapter bracket 22 are combined to form the adapter bracket 2, which is mainly fixed on the rear housing by using screws of the rear housing of the original liquid crystal flatpanel display device 3, and the metal grating membrane assembly 1 is fixed on the left andright adapter brackets 21 and theupper adapter bracket 22 by using machine-made screws, as shown in fig. 3.
After the assembly is completed, a specially-made tempered glassgrating film component 12 and a liquid crystal paneldistance limiting part 13 are assembled in the metalouter frame 11, and the whole metal grating film component 1 is fixed at a corresponding position in front of the liquid crystal flatpanel display device 3 at a distance from a display screen through the switching support 2 to form the 3D free three-dimensional display device. By using the structure mode, any part of the original liquid crystal flatpanel display equipment 3 is not needed to be damaged completely, only one set of metal grating membrane component 1 is added, and the metal grating membrane component 1 is assembled and disassembled at any time by adopting a screw of the original liquid crystal flatpanel display equipment 3, so that the structure mode has the characteristics of simple structure, simplicity and convenience in installation, low manufacturing cost and the like.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
