Abstract
There is provided that a kind of price is low, the unrestricted size of screen area, environment resistant light, the most heavy physics gain black rear-projection real, that the clear contrast of picture effect is high in black position are shielded firmly, 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 be the most satisfied, picture is clear, visible angle is high, color rendition is accurate, and far and near distance viewing effect is good.
Description
Technical field
The present invention relates to a kind of video display technology, particularly relate to a kind of display screen.
Background technology
Along with the fast development of economic technology, Screen Technology also obtains development at a 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: the visible angle time little, corresponding is the slowest, brightness
Low with contrast, maintenance cost is high, size limitation.
Summary of the invention
It is an object of the invention to: provide that a kind of price is low, the unrestricted size of screen area, environment resistant light, black position the most very
Heavy physics gain black rear-projection real, that the clear contrast of picture effect is high is shielded firmly, and it can overcome above-mentioned the deficiencies in the prior art, system
Make and quick, low cost easy to use, can be changeable according to oneself demand screen area, the requirement of picture display effect,
Can be the most satisfied, picture is clear, visible angle is high, color rendition is accurate, and far and near distance viewing effect is good.
It is an object of the invention to be realized by technical scheme once: a kind of physics gain black rear-projection is shielded firmly, and it is by Lycoperdon polymorphum Vitt
The transparent dark brown paper of rear-projection curtain, light black, transparent acrylic, medical ventolin, metal frame and fixed screw bolt composition.
Owing to using said structure, utilize that transparent acrylic daylighting is good, shock resistance, light weight, flatness good, make monoblock
One specular screen of screen.Transparent acrylic is smeared last layer medical ventolin uniformly, transparent for light black dark brown
Paper is layered on medical ventolin, then one layer of medical ventolin of uniform application on the transparent dark brown paper of light black, finally Lycoperdon polymorphum Vitt is carried on the back
Throw curtain to be not adhere on medical ventolin.The merit in gap is sealed owing to the characteristic of transparent acrylic has plus medical ventolin
Can, make the dark brown paper of light black and the lossless evil idea of Lycoperdon polymorphum Vitt rear-projection curtain and also need not any glue stick on transparent acrylic and
Do not come off.The transparent dark brown paper of light black is layered on the intermediate layer effect of vaseline and Lycoperdon polymorphum Vitt rear-projection curtain and is resistant to ambient light, with
Exempt from ambient light and affect picture effect.
Accompanying drawing explanation
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. 2 also serves as Figure of abstract.
In figure, 1 is transparent acrylic, and 2 is medical ventolin, and 3 is the transparent dark brown paper of light black, and 4 is Lycoperdon polymorphum Vitt back-projection screen
Cloth, 5 is medical ventolin, and 6 is metal edge frame, and 7 is fixed screw bolt.
Detailed description of the invention
A kind of physics gain black rear-projection is shielded firmly, and it is medical all that it smears last layer on transparent acrylic (1) uniformly
Intellectual circle (2), is layered on transparent for light black dark brown paper (3) on medical ventolin (2), upper all at the transparent dark brown paper of light black (3)
With smear one layer of medical ventolin (2), finally Lycoperdon polymorphum Vitt rear-projection curtain (4) is sticked on medical ventolin (2).Paving back of the body light black
Transparent dark brown paper (3) and Lycoperdon polymorphum Vitt want the middle bubble produced the when of throwing curtain (4), scrape away with scraper plate.Not so at projector
Aeration picture globality can be produced the when of projected picture.Finally with metal edge frame (4), whole picture peripheral frame is connected mutually
Rear fixed screw bolt (5).
Claims (4)
1. a thing increasing black rear-projection is shielded, firmly including by transparent acrylic, medical ventolin, the transparent dark brown paper of light black, ash
Color rear-projection curtain, metal edge frame, fixed screw bolt, it is characterised in that: price is low, the unrestricted size of screen area, environment resistant light,
The very heavy physics gain black rear-projection real, that the clear contrast of picture effect is high in black position is shielded firmly.
2. the physics gain black rear-projection told according to claim 1 is shielded firmly, it is characterized in that: uniform on transparent acrylic
Smear one layer of vaseline, transparent for light black dark brown paper sticked to above, toward the transparent dark brown paper mountain of light black smear one layer all
Intellectual circle adheres to Lycoperdon polymorphum Vitt rear-projection curtain.
3. the physics gain black rear-projection told according to claim 2 is shielded firmly, it is characterized in that: at Lycoperdon polymorphum Vitt back-projection screen front layer plus one
Plant the transparent dark brown paper of light black.
4. firmly shield according to the physics gain Lycoperdon polymorphum Vitt rear-projection belonging to claim 1, it is characterized in that: after having made screen, use metal edges
Frame connects fixed screw bolt mutually whole picture peripheral frame.
