Abstract
The invention relates to a fiber plain weaving rear projection screen and a production method thereof. The fiber plain weaving rear projection screen is formed by plain weaving light-transmittable fiber materials in a warp thread and weft thread manner. The production method of the fiber plain weaving rear projection screen has the characteristics of simple process and low cost and is suitable for industrial application. In addition, the fiber plain weaving rear projection screen has the advantages of lower reflection rate, better imaging quality and ensured imaging quality when the screen is positioned at the side front part and the ambient brightness is higher, and thereby the defect of a traditional rear projection screen is overcome.
Description
Technical field
The present invention relates to a kind of projection screen, particularly relate to a kind of fiber plain weave rear projection screen and working method thereof.
Background technology
The many stratified materials by materials such as resins of existing rear projection screen constitute; Because the stratiform screen surface is smooth relatively; High to the reflectivity of surround lighting, so screen side the place ahead and ambient brightness be when higher, screen imaging is very unintelligible; Have only when environment is very dark around, could present projected image preferably in the screen dead ahead.
This shows that above-mentioned existing rear projection screen obviously still has inconvenience and defective, and demands urgently further improving in structure and use.It is low how to found a kind of reflecting rate, good imaging quality, and in screen side the place ahead and ambient brightness still can guarantee new the fiber plain weave rear projection screen and the working method thereof of image quality when higher, belong to the current industry utmost point and need improved target in fact.
Summary of the invention
The technical matters that the present invention will solve provides a kind of fiber plain weave rear projection screen, makes its reflecting rate lower, and image quality is better, and in screen side the place ahead and ambient brightness still can guarantee image quality when higher, thereby overcome the deficiency of existing projection screen.
For solving the problems of the technologies described above, a kind of fiber plain weave of the present invention rear projection screen is to be formed by the fibrous material of the light-permeable mode plain weave with warp and parallel.
As a kind of improvement of the present invention, described fibrous material is fiber optics or resin fibre.
The diameter of described fibrous material is 0.012mm～5mm.
Described screen front and/or back also are provided with coating.
Described coating is smeared by the mixed solution of adhesive resin and light diffusing agent or reserving agent and is formed.
The coating of the teat of described warp and parallel crossover sites is cut or grinds away.
Described screen front and/or back also are coated with more than one in clarifier, ultraviolet light screener, water-proofing agent, hydrophilizing agent, the agent of flooding, the glass-film coating agent.
The present invention also provides a kind of working method of fiber plain weave rear projection screen, makes its technology simple, and cost is not high, and can produce the better rear projection screen of image quality.
For solving the problems of the technologies described above, the working method of a kind of fiber plain weave of the present invention rear projection screen is with the fibrous material of the light-permeable mode plain weave with warp and parallel.
As a kind of improvement of the present invention, described fibrous material is that diameter is fiber optics or the resin fibre of 0.012mm～5mm.
Specifically may further comprise the steps: the fibrous material of light-permeable is become screen with warp with the mode plain weave of parallel; Face is smeared the mixed solution of adhesive resin and light diffusing agent or reserving agent before or after screen; Cut or grind away with the covering of muller warp and parallel crossover sites teat; Following one or more medicaments are spread upon on the front and/or back of screen: clarifier, ultraviolet light screener, water-proofing agent, hydrophilizing agent, the agent of flooding, glass-film apply agent.
After adopting such design; It is simple that the working method of a kind of fiber plain weave of the present invention rear projection screen has technology, and the characteristics that cost is not high are suitable for application in industry; And it is lower that its product has a reflecting rate; Image quality is better, and in screen side the place ahead and ambient brightness still can guarantee the advantage of image quality when higher, thereby overcome the deficiency of existing rear projection screen.
Description of drawings
Above-mentioned only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, below in conjunction with accompanying drawing and embodiment the present invention is done further detailed description.
Fig. 1 is the structural representation of a kind of fiber plain weave of the present invention rear projection screen.
Fig. 2 is the plan structure synoptic diagram of a kind of fiber plain weave of the present invention rear projection screen.
Embodiment
See also shown in Figure 1ly, a kind of fiber plain weave of the present invention rear projection screen mainly is to utilize diameter to form with the direction of warp and weft plain weave for the fibrous material of light-permeables such as the resin fibre of 0.012mm～5mm or CORE fiber optics.Because the mode that adopts warp 1 and parallel 2 to interweave, screen surface of the present invention can form scattering clocklike, thereby enlarges the visible angle of rear projection screen, reduces the reflectivity to ambient light; And because screen has certain ventilative property, therefore under the influence of moving air, screen stability is also better.
Also can coating (CLAD layer) be set at face before or after the screen; This coating is to be smeared by the mixed solution of adhesive resin and light diffusing agent or reserving agent to form, and concrete smearing also can be accomplished through spraying or serigraphy (silk screen pringting) technology.
Please cooperate and consult shown in Figure 2ly, under the plain weave state, the right-angled intersection position of warp 1 and parallel 2 can form teat 3, the spacing between the teat 3, and just the interlace densities of warp 1 and parallel 2 can be selected as required.After coating sets; With muller cutting or grinding screen surface; Teat 3 coating surfaces are removed; Silvalin exposes, and on screen, smears clarifier, ultraviolet light screener, water-proofing agent, hydrophilizing agent, the agent of flooding, glass-film coating agent (coating agent) afterwards, thereby forms relatively flat and the high screen cover of transmittance.Be the light trend among the figure shown in the arrow, from the light at screen rear, a part of straight line sees through the above fibrage of one deck, and another part penetrates along the fiber conduction and through the part of removing coating, and two parts light is compound, forms the visible angle of broad.The sunk part 4 that leaves coating can play the effect that demonstrates bright image in the screen whole image then because of scribbling light diffusing agent etc., and the shadow table area that also screen is appeared simultaneously plays the effect of expansion.
A kind of fiber plain weave of the present invention rear projection screen can show high distinctness, high luminosity, more accurate projection image, not only applicable to the large multimedia image, also is suitable for being applied on the luminous plate of dynamic image information such as presenting advertisement and news report.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection scope of the present invention.
