It needs except good projector, one piece of exquisite optical screen is more essential.It may be said that projector's technology increasingly
Today of homogeneity, the quality of projection screen just directly determines the perfect degree of projected picture, by projector and optical screen
Collocation, be only a complete projection display system.
Optical screen: optical screen can make projector light strong and environment light by what a series of fine optical textures formed
The projection screen redistributed in screen construction by force.Its main feature is that environment light and enhancing projector can effectively be covered
Light intensity, promoted picture contrast, luminance gain, color reducibility, respectively rate etc., meet the needs of people are to superelevation image quality.
Currently, the projection screen used on the market is broadly divided into hard curtain and supporting part.Supporting part fixed form mainly uses bullet
There is the object form of stretching elasticity curtain to be made to form a plane and be fixed on the frame of surrounding for spring, elastic string etc..Hard curtain is consolidated
Determining mode, mainly use sticks with glue mask on rigid objects surface, such as honeycomb aluminum plate, aluminium-plastic panel, steel plate, then exists
Rigid objects surrounding assembly frame is for covering and decorating.Installation, use and demolition are all inconvenient.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide one kind and magnetic material is arranged on optical screen
Material, in projection screen in use, screen need to be only attached to setting magnetic material background board or wall on, installation and
Convenient disassembly is effectively simplified screen installation difficulty using magnetic ferroic material, can be avoided appearance tradition clamping mounting means pair
The magnetic optical projection screen that screen damages.
The purpose of this utility model is achieved through the following technical solutions: a kind of magnetic optical projection screen, in light
It learns and magnetic material is set inside the back side or optical diaphragm of diaphragm.
Further, the magnetic material is fitted in light by PET double-sided adhesive, adhesive sticker, optic-solidified adhesive or EVA hot-melt adhesive
Learn the back side of diaphragm.Magnetic material uses iron powder paper or magnetic rubber.
Further, the optical diaphragm is made of the optical film layer for being coated with the fine optical texture of multilayer, is successively wrapped
Hardened layer, the first PET base membrane layer, color layers, the 2nd PET base membrane layer and optical structure layers are included, the optical structure layers are using mixed
Conjunction has the glue of iron powder or magnetic powder to be made.
Further, the optical diaphragm is made of the optical film layer for being coated with the fine optical texture of multilayer, is successively wrapped
Include hardened layer, the first PET base membrane layer, color layers, the 2nd PET base membrane layer and optical structure layers, the magnetic material by printing,
The mode of spraying, plating or coating is produced in optical structure layers.
The beneficial effects of the utility model are: the utility model provides one kind is arranged magnetic material on optical screen,
In projection screen in use, need to only be attached to screen on the background board or wall of setting magnetic material, pacify installation and dismantling
It unloads conveniently, the projection screen of the utility model does not need fitting honeycomb aluminum plate, can reduce the packaging volume and again of product 70%
Amount reduces packaging, transport and installation cost, while being effectively simplified screen installation difficulty using magnetic ferroic material, can be avoided
There is the case where traditional clamping mounting means damages screen.
Detailed description of the invention
Fig. 1 is the structural schematic diagram one of the magnetic optical screen of the utility model；
Fig. 2 is the structural schematic diagram two of the magnetic optical screen of the utility model；
Fig. 3 is the structural schematic diagram three of the magnetic optical screen of the utility model.
Specific embodiment
The technical solution of the utility model is further illustrated in the following with reference to the drawings and specific embodiments.
Embodiment 1
As shown in Figure 1, a kind of magnetic optical projection screen, is arranged magnetic material 4, the magnetic at the back side of optical diaphragm 1
Property material 4 is fitted in the back side of optical diaphragm 1, the magnetism by PET double-sided adhesive, adhesive sticker, optic-solidified adhesive or EVA hot-melt adhesive
Iron powder paper or magnetic rubber can be used in material.When using the optical screen, dress is used on the metope 2 for needing to install projection screen
It repairs glue and is bonded one layer of magnetic rubber or iron powder paper 3, be then placed into the optical diaphragm for being fitted with iron powder paper or magnetic rubber
It is fitted on the metope of magnetic rubber or iron powder paper.Collocation mode when installation is, if the optical diaphragm back side is bonded
Be iron powder paper, then on metope just fitting magnetic rubber；If the fitting of the optical diaphragm back side is magnetic rubber, just it is bonded on wall
Iron powder paper.The optical diaphragm back side, which is bonded one layer of iron powder paper or magnetic rubber, can also play the role of the fine optical texture of protection.Magnetic
Inhale optical screen can need using when load at any time, do not need using when remove spool at any time, be not take up excessive sky
Between, it is very convenient and practical.
Embodiment 2
As shown in Fig. 2, magnetic material is arranged in the inside of optical diaphragm 1, the optical diaphragm is micro- by being coated with multilayer
