Description
Technical field
The present invention relates to orthographic projection optical screen technical fields, in particular to orthographic projection optical screen and installation side
Method.
Background technology
Growing 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 is drawn 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 televisions, 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 Fes 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
For the 100 inch optical projection screens packaging of Chengdu Fscreen Science ＆ Technology Co., Ltd., the size of packing case has reached 2390*
1430*90mm, and the national standard size of common house I class man lifts only only has 900kg-1000kg load-carrying sizes
For：The following size of 900*2100mm, 900kg load-carrying is：800*2100mm, 1150kg load-carrying size is：1000*2100mm, sedan-chair
Compartment size 900kg or less is：1350*1400mm, 900kg-1000kg load-carrying car size are 1350*1600mm, and 1150kg is carried
Weight car size is 1500*1800mm.The product packaging volume of this hard screen form is excessive, has exceeded the size of man lift,
To the serious inconvenience of band of registering one's residence upstairs, at the same hard curtain weight containing packing case reaches 60kg or so, needs 3~4 talents to carry, on
Building installation is extremely difficult, the apparent disadvantage such as other also of high cost, waste materials, not energy-efficient environmental protection.

S1012, other multiple magnetic films 410 are spliced centered on the magnetic film 410 for fitting in metope successively in viscous
It is affixed on the outer rim of the magnetic film 410 of metope.
That is, in the present embodiment, when multiple magnetic films 410 are adhered to metope, the magnetic one of among adhering to
Film 410, remaining magnetic film 410 are pasted on the basis of the magnetic film 410 for being adhered to metope, are avoided that two neighboring around
The excessive imaging image quality for influencing orthographic projection optical screen 10 in gap before magnetic film 410.
Further, after multiple magnetic films 410 are adhered to metope, using plastic spatula along the bonding direction of magnetic glue
Air under multiple magnetic films 410 is struck off, ensures that magnetic film 410 is bonded completely with metope, prevent from being formed air bubble influence at
As image quality.
It should be noted that the bonding direction of plurality of magnetic film 410 is the orientation of multiple magnetic films 410.
In addition, in the present embodiment, before magnetic glue-line 400 is attached at metope, needing to carry out testing flatness to metope.
Wherein, if the flatness of metope is less than or equal to 0.5mm, the adherency of magnetic glue-line 400 can be carried out on metope between.Such as
The flatness of fruit metope be more than 0.5mm and less than or equal to 3mm when, need to metope carry out leveling so that metope it is smooth
Degree is less than 0.5mm, then carries out the adherency of magnetic glue-line 400 again.If the flatness of metope is more than 3mm, need to use other
Measure is installed, such as installs on metope the load-bearing part that other flatness are less than or equal to 0.5mm, and by magnetic glue-line 400
It is adhered on the load-bearing part；The viscous of magnetic glue-line 400 is carried out alternatively, changing another and meeting metope of the flatness less than or equal to 0.5mm
It is attached.
S102, by 300 magnetic absorption of soft magnetosphere in multiple sides of the magnetic film 410 far from metope.
Wherein, in the present embodiment, step S102 includes：
By soft magnetosphere 300 along first direction successively magnetic absorption on multiple magnetic films 410.
It should be noted that first direction refer to be multiple magnetic films 410 orientation.That is, in the present embodiment,
By soft magnetosphere 300 soft magnetosphere 300 and multiple magnetic films are can guarantee in multiple magnetic films 410 along first direction successively magnetic absorption
