Abstract
The utility model discloses a multilayer microstructure film sheet composite rear projection screen. The front side of the basal layer of the transparent film with gray pigment is compounded with the plastic film with straight burr structure to be a display layer, and the back side of the basal layer is compounded with the plastic film with multi-twill structure to be a projection layer, being compounded into an entirety through pressing and agglutinating. The entirety of the screen is in gray, and the frame is provided around the screen.
Description
Affiliated technical field
The utility model is about projection screen, particularly the rear projection screen that is composited by the multiplelayer microstructure diaphragm.
Background technology
Projection screen can be divided into front projection screen and rear projection screen, and common front projection screen mostly is ordinary screen, so its brightness, and contrast and gain are all very low.Can not under bright environment, use.Kai Fa optical back projection screen in recent years, its brightness, contrast and gain have all had raising in various degree, but because it is monoblock die casting, cause difficulty in process, restricted development, exist volume big in addition, heavy, problems such as transportation difficulty and surface structure part easy damaged.
Summary of the invention
Can not under bright environment, use in order to overcome existing projection screen, monoblock extrusion process complexity, the big weight of volume is big, deficiencies such as surface structure easy damaged, the utility model provides a kind of rear projection screen, and it can not only use under bright environment, and technology is easy.Weight is less than 1/10th of monoblock die casting, again can integral body rolls transportation and is difficult for injured surface structure etc.
The technical scheme that its technical matters that solves the utility model adopts is: be " basal layer " with a transparent membrane that contains grey pigment, basal layer positive compound on the plastic film of band straight burr structure be " display layer ", the compound plastic film of many twill structures of basal layer reverse side be " throw layer ".Become one by the pressurization bonding, screen is canescence.Add dark border all around to increase the integrally-built intensity of screen and to strengthen the edge display effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
The rear projection screen front view that accompanying drawing 1 multiplelayer microstructure diaphragm is combined into.
1 frame .2 screen.
The rear projection screen cut-open view that accompanying drawing 2 multiplelayer microstructure diaphragms are combined into.
1 frame .2 screen .3 display layer .4 basal layer .5 throws layer.
The rear projection screen side view that accompanying drawing 3 multiplelayer microstructure films are combined into.
1 frame .2 screen.
Embodiment
In Fig. 1, frame (1) becomes one with screen (2) bonding, and to increase the integrally-built intensity of screen, frame (1) is that black is to strengthen the edge display effect.
In Fig. 2, display layer (3) is compounded in the front of basal layer (4) by the pressurization bonding.Projection layer (5) bonds by pressurization and is compounded in the reverse side of basal layer (4), and screen is canescence.
Claims (2)
1. projection screen, the rear projection screen that is combined into of multiplelayer microstructure diaphragm particularly, it is characterized in that in " basal layer " front that contains grey pigment transparent membrane, the compound plastic film of going up band straight burr structure is " display layer ", the plastic film of many twill structures is " a projection layer " the basal layer reverse side is compound, and screen integral body is canescence.
2. according to the projection screen of claim 1, it is characterized in that: the basal layer of the display layer of straight burr structure and grey pigment transparent membrane and the projection layer of many twill structures, pressurization is bonded to one, and dark border is installed all around.
