Description
Technical field
The utility model relates to orthographic projection optical screen technical fields, in particular to orthographic projection optical screen and throwing
Image device.
Background technique
Increasingly developed with shadow casting technique, projector's image effect that optical diaphragm is presented of arranging in pairs or groups is more and more perfect, by
To liking for more and more consumers for pursuing super large picture effect, however to reach exquisite picture and effect is presented, in addition to
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 projection
The collocation of screen is only a complete projection display system.
Optical projection screen: optical projection screen can make projector light strong by what a series of fine optical textures formed
The projection screen redistributed in screen construction with environmental light intensity.Its main feature is that can effectively weaken environmental light intensity and enhancing
The light intensity of projector promotes picture contrast, luminance gain, color reducibility, respectively rate etc., meets people and draws to superelevation
The demand of matter.
Optical projection screen is broadly divided into hard curtain and supporting part at present.Supporting part fixed form mainly uses spring, elastic string etc.
Object form with stretching elasticity makes curtain form a plane and is fixed on the frame of surrounding.Supporting part uses also go out for a long time
Now relaxation, fold etc. influence display effect, while supporting part frame entirety seems thick and heavy, with present OLED ultra-thin television, narrow side
Trend be not inconsistent.The fixed form of hard curtain is mainly using sticking with glue mask on rigid objects surface, such as honeycomb aluminum plate, aluminium
Mould plate, steel plate etc., then in rigid objects surrounding assembly frame for covering and decorating.Such hard curtain is installed to need on wall
Pre- sunk screw, damages metope, while screen is very heavy, uses and dismantles and is all inconvenient.
Optical projection screen on sale currently on the market has Janpanese Printing Co., Ltd (DNP) and Chengdu Fiss spy section
Skill Co., Ltd is all to be supported with thick and heavy rigid back, then be aided with hard curtain made of the accessories such as Decorative frame, pendant, with
