Abstract
The utility model relates to a digital light processing (DLP) screen capable of reducing optical split seams, which consists of a screen body, a connecting component, a connecting element b and a screen frame, wherein the screen body is connected with the connecting element b through the connecting component, a connecting part consists of a connecting element a and a bonding layer connected with the connecting element a, and the thickness of the bonding layer is 0.1mm. The DLP screen has a reasonable design, and the optical split seams of a back projection screen is greatly reduced, so the split seam of the DLP screen is reduced from the existing 0.5mm to 1mm to about 0.3mm to 0.5 mm, the integral visual split joint effect of the back projection screen wall is improved to a great degree, in addition, the bonding layer is ultraviolet (UV) glue water, and the intensity and the stability of bonding objects are perfectly ensured, so the whole body after the bonding completion can not deform, a uniform edge with good linearity can be formed on the cured glass end surface.
Description
Technical field
The utility model relates to a kind of screen, especially a kind of DLP screen that can reduce the optics piece.
Background technology
At present, the fixed form of existing screen is that to adopt double sticky tape and corresponding web member to carry out bonding, utilizes the web member bound edge to realize again.Because the thickness of double faced adhesive tape is 0.2mm, web member thickness is 0.05mm, and web member thickness is 0.05mm, so spliced perfect optics piece is (0.2+0.05+0.05) x2=0.6mm.If add the error amount 0-0.5mm that out-of-flatness brought of double sticky tape, so spliced actual optics piece length should be 0.6 to 1.1 millimeter.Because the optics piece is bigger, therefore can influence the whole splicing effect of screen wall.
The utility model content
At the weak point that exists in the above-mentioned technology, the utility model provides a kind of length of dwindling the optics piece of screen, improves the DLP screen that can reduce the optics piece of the whole vision splicing effect of screen more.
For achieving the above object, the utility model provides a kind of DLP screen that can reduce the optics piece, constitute by screen body, link, web member b and screen frame, described screen body is connected with described web member b by link, described coupling part is made of web member a and the tack coat that is connected with described web member a, and the thickness of tack coat is 0.1mm.
The bottom of described tack coat is connected with described screen body.
Described tack coat is a UV class high strength bond thing.
Described screen body is made of the mute light glass of the optics that connects successively mutually, cylindrical mirror, Fresnel Lenses and optics white glass.
Between described web member a and described screen frame, also be provided with layers of two-sided.
The back side of described optics white glass is connected with described screen frame.
Compared with prior art, the utlity model has following advantage:
The DLP screen that can reduce the optics piece that the utility model provides, constitute by screen body, link, web member b and screen frame, the screen body is connected with web member b by link, the coupling part by and be connected the layer constitute, the layer thickness be 0.1mm.The utility model is reasonable in design, very big reduction the optics piece of rear projection screen, the splicing seams that makes the DLP screen is reduced to 0.3mm to about the 0.5mm from existing 0.5mm-1mm, has improved the whole vision splicing effect of rear projection screen curtain wall to a great extent; In addition, because layer is UV glue (a high strength bond thing), so integral body deformation can not take place after solidifying, the glass end face after the curing also can form an even and good limit of rectilinearity.
Description of drawings
Fig. 1 is a structural drawing of the present utility model;
Fig. 2 is the splicing effect figure of Fig. 1.
The main element symbol description is as follows:
1 web member b, 2 web member a, 3 layers of two-sided
4 screen frames, 5 tack coats, 6 optics white glasses
7 Fresnel Lenses, 8 cylindrical mirrors, the 9 optics light glass of making mute
Embodiment
For clearer statement the utility model, the utility model will be further described below in conjunction with accompanying drawing.
As Fig. 1 and shown in Figure 2, the utility model provides a kind of DLP screen that can reduce the optics piece, constitute by screen body, link, web member b and screen frame 4, the screen body is connected with web member b1 by link, the coupling part is made of web member a2 and the tack coat 5 that is connected with web member a2, and the bottom of tack coat 5 is connected with the upper end of screen body, wherein, this tack coat 5 forms for UV solidifies the back, and its thickness is 0.1mm.The screen body is made of the mute light glass 9 of the optics that connects successively mutually from outside to inside, cylindrical mirror 8, Fresnel Lenses 7 and optics white glass 6, and the back side of optics white glass 6 is connected with screen frame 4.Between web member a2 and screen frame 4, also be provided with layers of two-sided 3.
The utility model has adopted high strength bond thing and the fixed form that combines to the fixed form of screen, replace double faced adhesive tape with the high strength bond thing, the thickness of high strength bond thing layer is 0.1mm after fixing, thickness is 0.05m, web member b thickness is 0.05mm, so the desirable piece size behind the screen splicing is (0.1+0.05+0.05) x2=0.4mm.Because the high strength bond thing is a liquid form, so integral body does not produce deformation after solidifying, glass end face after the curing can form an even and good limit of rectilinearity, its error at 0.1mm between the 0.mm2, so the actual optics piece size of the last splicing of screen should be between 0.4 to 0.6 millimeter.
More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
Claims (6)
1. DLP screen that can reduce the optics piece, constitute by screen body, link, web member b and screen frame, described screen body is connected with described web member b by link, it is characterized in that, described coupling part is made of web member a and the tack coat that is connected with described web member a, and the thickness of tack coat is 0.1mm.
