Abstract

The invention provides a physical gain gray rear-projection hard screen which is low in price, unrestricted in screen area size, clear in image effect and high in contrast ratio. The physical gain gray rear-projection hard screen can overcome shortcomings of the prior art, manufacturing and utilization of the physical gain gray rear-projection hard screen are simple, convenient and efficient, the cost is low, the screen area can be adjusted according to personal requirements, and requirements of image display effects can be fully met. The physical gain gray rear-projection hard screen is clear in image, high in visual angle, accurate in color reproduction and good in far and near viewing effect.

Description

Hard screen of physics gain Lycoperdon polymorphum Vitt rear-projection and preparation method thereof
Technical field
The present invention relates to a kind of video display technology, more particularly to a kind of display screen.
Background technology
With the fast development of economic technology, Screen Technology also obtains the development of high speed.Display screen classification is mainly now LED display, LCDs.These display screen the deficiencies in the prior art, LED electronic television screen：Expensive, maintenance cost High, power consumption is big, definition is low, closely viewing effect poor.LCDs：Visible angle is little, the corresponding time is excessively slow, brightness , maintenance cost low with contrast is high, size limitation.
Content of the invention
The purpose of the present invention is：There is provided that a kind of price is low, the unrestricted size of screen area, the clear contrast of picture effect high Physics gain Lycoperdon polymorphum Vitt rear-projection firmly shield, it can overcome above-mentioned the deficiencies in the prior art, make and quick, low cost easy to use, Can be changeable according to oneself demand screen area, the requirement of picture display effect, can fully meet, picture is clear, can Angle is high, color rendition is accurate, and far and near distance viewing effect is good.
The purpose of the present invention is to be realized by technical scheme once：A kind of physics gain Lycoperdon polymorphum Vitt rear-projection is shielded firmly, and it is by rear-projection Curtain, transparent acrylic, medical ventolin, metal frame and fixed screw bolt composition.
Due to adopting said structure, using transparent acrylic daylighting is good, shock resistance, light weight, flatness good, make monoblock One specular screen of screen.Uniformly smear last layer medical ventolin on transparent acrylic, then back-projection screen is layered on all On intellectual circle, the characteristic due to transparent acrylic has, plus medical ventolin, the function of sealing gap, be back-projection screen no damage and And stick on transparent acrylic without any glue and will not fall off.
Brief description
It is described further with enforcement row below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the cross-sectional structure schematic diagram of the present invention.
Fig. 1 also serves as Figure of abstract.
Specific embodiment
A kind of physics gain Lycoperdon polymorphum Vitt rear-projection is shielded firmly, and it is in transparent acrylic（1）On uniformly smear last layer vaseline （2）, then back-projection screen（3）Stick to vaseline（2）On.Paving back-projection screen（3）When vaseline（2）And back-projection screen（3） Middle long-living bubble, is scraped away with scraper plate.Not so bubble can be produced when projector picture, and to affect picture complete Whole property.Finally use metal edge frame（4）Whole picture peripheral frame phase is connected rear fixed screw bolt（5）.

Claims (3)

1. a kind of thing increases Lycoperdon polymorphum Vitt rear-projection and firmly shields, including by transparent acrylic, rear-projection curtain, medical ventolin, metal edge frame, solid Determine carriage bolt it is characterised in that：Picture is clear, visible angle is high, color rendition is accurate, far and near distance viewing effect is good, picture Size is changeable.
2. firmly shielded according to the physics gain Lycoperdon polymorphum Vitt rear-projection that claim 1 is told, it is characterized in that：Uniform on transparent acrylic Smear one layer of vaseline, then back-projection screen is sticked on vaseline.
3. the physics gain Lycoperdon polymorphum Vitt rear-projection according to belonging to claim 2 is shielded firmly, it is characterized in that：After having made screen, use metal edges Frame connects fixed screw bolt whole picture peripheral frame phase.
