Description
Technical field
The utility model relates to projection screen, especially relates to a kind of superpower anti-ambience light projection curtain.
Background technology
Because the limitation of large scale liquid crystal display production cost and technical bottleneck, in the demonstration demand that exceedes 84 inches, at presentGeneral method is to adopt the mode of orthographic projection or back projection to realize. Generally, orthographic projection system can be thrown in high efficiency utilizationThe brightness resource of shadow machine, but because this type systematic is very responsive to the surround lighting of field of employment, conventionally need to be at more dim ringUnder border, use, and best for preventing that spectators from blocking projection ray, adopt the mode of lifting, cause this type systematic conventionally to installInconvenient secondary dismounting after finishing. Back-projection system can fine opposing ambient light interference, and can not blocked projection by spectatorsLight, but in the time that the gain of back projection curtain is too low, the brightness resource of the projector that significantly decayed, and gain when back projection curtainWhen raising, significantly reduce contrast and the color rendition degree of picture, and easily occurred fuzzy sense, be at careful pictureSystem takes up room large.
In recent years, there are the successively research and development of production firm of multiple projector volume production to go out ultrashort Jiao's laser projection, such projection functionEnough in very short projector distance, project larger picture. This series products is applied in front projection display system and can be effectively solvedSpectators are blocked the problem of projection ray, and can adopt the mode filling that projector is installed, and conveniently orthographic projection system are tieed upProtect and secondary dismounting. But such projector self can not solve the orthographic projection system problem too sensitive to surround lighting.
Summary of the invention
It is strong to surround lighting resistivity that the purpose of this utility model is to provide, and can effectively improve ultrashort burnt laser projection light profitBy rate, the picture color demonstrating is true to nature, and brightness and contrast is high, and curtain base good toughness, can adopt multiple mounting modes, can roll upThe superpower anti-ambience light projection curtain of one of bent packaging and transport.
The utility model is provided with back side light-absorption layer, plane curtain base, zigzag curtain base, front light-absorption layer, optical diffusing reflective construction layer;Plane curtain base is located between back side light-absorption layer and zigzag curtain base, and front light-absorption layer is located at the sawtooth top of zigzag curtain base, opticsDiffuse reflective structure layer is located at sawtooth below.
The back side of plane curtain base and the front of back side light-absorption layer are bonding; The back side of the front of plane curtain base and zigzag curtain base is bonding.
The sawtooth end face of the bottom surface of front light-absorption layer and zigzag curtain base is bonding; The back side of optical diffusing reflective construction layer and zigzag curtainThe sawtooth bottom surface of base is bonding.
Each several part structure of the present utility model adopts bonding mode to be fixed into an overall structure.
Described back side light-absorption layer can adopt the back side to be plane black light-absorbing layer, and its composition is black PET extinction material, when thisUtility model is not, while leaning on wall to install, can absorb the interference light from the projection screen back side completely by back side light-absorption layer, guarantees to throwShadow picture is not affected, and not reflective, can not affect projection screen other light effects functions below.
Described plane curtain base can, by being made up of polymer composite, have superpower toughness, can support common electric drill perforate, curtain baseThere will not be cracking phenomena, can use the multiple accessories such as metal screw, spring, plastics cableties to carry out the installation of tightening of various ways.
Described zigzag curtain base can be made up of polymer composite, has superpower toughness, can support common electric drill perforate, curtain baseThere will not be cracking phenomena, can use the multiple accessories such as metal screw, spring, plastics cableties to carry out the installation of tightening of various ways;For convenience of production technology, two parts curtain base is die cast respectively, then this two parts curtain base is carried out to strong binding, plane curtain baseMain Function be to support back side light-absorption layer, the Main Function of zigzag curtain base is to support front light-absorption layer and optical diffusing reflective constructionLayer.
Described front light-absorption layer also can adopt black PET extinction material, and optical diffusing reflective construction layer can adopt reflective PU material and establishBe set to unrestrained wavy.
From the major part in projection screen front disturb light by direct irradiation at front light-absorption layer, thereby inhaled completely by front light-absorption layerReceive; In the time that the fraction from projection screen front disturbs light to be radiated at optical diffusing reflective construction layer, be by upper owing to disturbing lightUnder direction, irradiate, major part will be reflexed to lower one deck front light-absorption layer by optical diffusing reflective construction layer, and then be absorbed.
The light that ultrashort burnt laser projection projects, owing to being to project obliquely, will all be incident upon the diffuse reflective structure of projection screenOn layer, by the diffuse reflection of this structure sheaf, most throw lights are watched position by projecting the spectators that are positioned at projection screen dead aheadPut; Simultaneously due to ultrashort burnt laser projection be loaded on projection screen dead ahead, therefore can conveniently safeguard and dismounting.
The utility model effectively solves orthographic projection system, and to disturbing, light resistivity is poor, brightness is low, easily blocked throwing by spectatorsShadow light, be inconvenient to safeguard the problem of dismounting, solve simultaneously back-projection screen cannot effectively utilize projector's brightness resource, fuzzy pictures,Large problem takes up room; Can increase substantially the utilization rate of ultrashort burnt laser projection brightness resource and ultrashort burnt characteristic, showThe picture illustrating is careful clear, and contrast is high, and color is true to nature; Can carry out easily peripheral structure installation, can curling packaging and fortuneDefeated.
