Structure for weakening abrasion of electric grating picture

Technical Field

The utility model relates to the technical field of electric gratings, in particular to a structure for weakening abrasion of an electric grating picture.

Background

The change of viewer's visual angle is realized through the picture behind the grating panel of round trip movement to electronic grating drawing to let the viewer can see the continuous manifestation of a plurality of pictures at a fixed position (visual angle), reach the effect of broadcast animation, because the optical characteristic of product, the content of picture must paste the grating panel tightly, just can guarantee that the distance of prism convex surface peak and picture satisfies the focus size, that is to say: the device is characterized in that a clear image can be obtained at a watching position only when a picture is tightly attached, otherwise, defocusing display can be generated, a view image becomes blurred, and adjacent image information cannot be analyzed clearly, so that serious ghost images cannot be displayed. However, the movement of the picture can cause friction between the picture and the raster panel, and although the movement distance is small and the speed is slow, the picture and the raster panel can be worn and scratched, and the viewing effect is affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems in the background art and provides a structure capable of reducing abrasion between a grating panel and a moving drawing board in an electric grating drawing.

The technical scheme of the utility model is as follows: the utility model provides a weaken structure of electronic grating drawing wearing and tearing, includes grating panel and reciprocating motion's drawing board, and the grating panel sets up in the front side of drawing board, be provided with the super PET thin slice of passing through oDLC processing between grating panel and the drawing board, the gross thickness of super PET thin slice and grating panel equals the focus distance of the prismatic convex surface of grating panel.

Preferably, the number of the ultra-transparent PET sheets is 1, and both surfaces of the ultra-transparent PET sheets are subjected to the ocld treatment.

Preferably, the number of the super-transparent PET thin sheets is 2, the two super-transparent PET thin sheets are respectively bonded and fixed on the grating panel and the drawing board through back glue, and the surfaces, close to each other, of the two super-transparent PET thin sheets are all processed through oDLC.

Compared with the prior art, the utility model has the following beneficial technical effects:

Detailed Description

The technical solution of the present invention is further explained with reference to the accompanying drawings and specific embodiments.

Example one

As shown in figure 1, the structure for weakening the abrasion of the electric raster picture comprises a raster panel 1 and a drawing board 2 which moves back and forth, wherein the raster panel 1 is arranged on the front side of the drawing board 2, an ultra-transparent PET sheet 3 processed by oDLC is arranged between the raster panel 1 and the drawing board 2, the DLC is a substance which is composed of carbon elements, is similar to diamond in property and has a graphite atom composition structure, is a free combination product of carbon atoms, is often combined in a form of SP2 or SP3 bond to generate a metastable material, is an amorphous carbon film, has the excellent characteristics of both diamond and graphite, has high hardness and high elastic modulus, low friction factor, abrasion resistance and excellent vacuum tribological characteristics, also has high resistivity and excellent optical performance, and is very suitable for being used as an abrasion-resistant coating, the oDLC coating technology is to coat a diamond-like film on the surface of glass by adopting a nano coating mode, the method has the characteristics of convenience in control, large-area layer thickness uniformity and the like, the ultra-transparent PET sheet processed by the oDLC technology has good wear resistance, so that the friction between the grating panel 1 and the drawing board 2 can be greatly reduced, the loss caused by the grating panel 1 and the drawing board 2 is avoided, meanwhile, the buffer effect can be achieved in the working process of the device, the long-term use of the product is ensured, and the surface of the ultra-transparent PET sheet 3 can be processed by other wear-resistant and scratch-resistant technologies;

the total thickness of the super-transparent PET sheet 3 and the grating panel 1 is equal to the focusing distance of the prism convex surface of the grating panel 1, when the thickness of the single super-transparent PET sheet 3 is n, the thickness of the grating panel 1 needs to be reduced by n, so that the focusing point of the prism convex surface of the grating panel 1 can be ensured to be consistent with the drawing board 2, and the content on the drawing board 2 can be clearly seen, so that the situation that the content on the drawing board 2 cannot be clearly seen due to defocusing is avoided;

the number of the super-transparent PET sheets 3 is 1, and both sides of the super-transparent PET sheets 3 are processed by oDLC, so that both sides of the grating panel 1 and the drawing board 2 can be in contact with each other, and further, the friction force between the grating panel 1 and the drawing board 2 can be reduced.

Example two

As shown in fig. 2, the structure for weakening abrasion of an electric raster picture, provided by the utility model, comprises a raster panel 1 and a drawing board 2 which moves back and forth, wherein the raster panel 1 is arranged on the front side of the drawing board 2, an ultra-transparent PET sheet 3 processed by oclc is arranged between the raster panel 1 and the drawing board 2, and the total thickness of the ultra-transparent PET sheet 3 and the raster panel 1 is equal to the focusing distance of the prism convex surface of the raster panel 1;

this embodiment still includes, the quantity of super PET thin slice 3 is 2, when the thickness of monolithic super PET thin slice 3 is n, need to reduce 2n with the thickness of grating panel 1, and two super PET thin slices 3 are fixed in grating panel 1 and drawing board 2 through the gum bonding respectively, the one side that two super PET thin slices 3 are close to each other all processes oDLC and handles, when drawing board 2 removes, can make two super PET thin slices 3 rub through the one side that oDLC handled, can also directly not have prismatic plane and drawing board 2 direct coating scratch-resistant liquid film at grating panel 1, because the influence of coating thickness to optical distance can be neglected almost, so grating panel 1 needn't reduce thickness, but scratch-resistant liquid film can not produce the high temperature process when using, if the high temperature can produce the deformation to the material, directly produce negative effects to grating formation of image.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
