Fig. 2 is using state schematic diagram of the present utility model.
[embodiment]
The following example is to further explanation of the present utility model and supplements, and does not constitute any limitation the utility model.
For the interference that opposing surround lighting causes imaging picture, solve image blurring, distortion, brightness decline, the white vaporific problem such as seriously, the utility model proposes a kind of novel projection screen, it utilizes the raised line 2 be horizontally arranged at interval to block and absorbing environmental light, utilize the projection imaging layer 3 be located between raised line 2 to carry out projection imaging, thus the image quality of existing projection screen can be improved.The Novel Microstructure projection screen that can use in strong light environment of the present utility model is used for orthogonal projection and uses.
As shown in Fig. 1 ~ Fig. 2, the projection imaging layer 3 that can comprise base material 1, be located at the raised line 2 on base material 1 and be located between raised line 2 at the Novel Microstructure projection screen of strong light environment use of the present embodiment.
Described base material 1 is made up of light absorbent, and material as dark in black sheet material, black sheet material, black film material, grey sheet material, grey sheet material, grey film material etc. is made.Particularly, it can be made up of materials such as the PVC of dark color, TPU, EVA, PMMA, PC, silica gel, rubber.The size of described base material 1 determines the size of projection screen.The raised line 2 of several parallel interval is provided with on the surface in the side of described base material 1.Described raised line 2 is one-body molded with described base material 1.During enforcement, on the surface of the base material such as plastic film material, plastic plate 1, form described raised line 2 by technology such as engraving or roll-ins.Described raised line 2 is vertically formed at the surface of described base material 1.Such as, during normal projection, described base material 1 is normally vertically placed, then described raised line 2 protrudes from the front side surface of described base material 1 in horizontal level.The cross sectional shape of described raised line 2 can be square, trapezoidal, triangle or other shapes.In the present embodiment, the cross sectional shape of described raised line 2 is trapezoidal, and its upper and lower both side surface tilts in obtuse angle with the front side surface of described base material 1 respectively.In the present embodiment, be that equidistantly between it, the distance at interval can be determined according to the quality of the required imaging picture reached between described raised line 2 and raised line 2.In the present embodiment, between described raised line 2 and adjacent raised line 2, the distance at interval is less than 0.5mm, preferred 0.2mm.For ease of projection imaging, between described raised line 2 and raised line 2, be provided with projection imaging layer 3.In the present embodiment, described projection imaging layer 3 is formed on the surface by projection imaging paint or projection imaging Ink Application or the base material 1 be printed between raised line 2 and raised line 2.Certainly, also described projection imaging layer 3 is formed by technological means such as air brushing, plating, electrophoresis.Be formed at the consistency of thickness of projection imaging paint between different raised line 2 and raised line 2 or ink, thus make the flush with outer surface of described projection imaging layer 3.For absorbing and blocking surround lighting, reduce surround lighting to the interference of projection imaging, the height of described raised line 2 is greater than the thickness of described projection imaging paint or ink, when surround lighting is irradiated from the front at a certain angle, most surround lighting just can be blocked by raised line 2 and cannot directly project on described projection imaging layer 3.It should be noted that, the thickness of described raised line 2, width and between interval all very trickle, the naked eyes of people cannot identification, and for ease of showing the concrete structure of described raised line 2 in Fig. 1 ~ Fig. 2, the ratio of this raised line 2 is amplified, in reality, the ratio of itself and described base material 1 is not general as shown in drawings.Therefore, Fig. 1 ~ Fig. 2 do not represent of the present utility model can strong light environment use the general ratio of Novel Microstructure projection screen or the structure of correct proportions, its only for show of the present utility model can strong light environment use Novel Microstructure projection screen structure composition.In addition, because described raised line 2 structure is trickle, living human eye cannot discover, therefore, even if described raised line 2 is made up of the material such as black or grey and is different from described projection imaging layer 3, but it still can not affect visual experience, it both can not form black line together before vision, user also can not be allowed to perceive on projection screen and there is black line together.
By this, just the Novel Microstructure projection screen that can use in strong light environment of the present utility model is defined by base material 1, raised line 2 and projection imaging layer 3.During use, as shown in Figure 2, described projector equipment 4, as projector is positioned over the front of the Novel Microstructure projection screen that can use in strong light environment of the present utility model, the highest coboundary being no more than projection screen in its position.Wherein, the A in Fig. 2 is to representing visual angle central horizontal line view direction, and B is to representing surround lighting incident direction.Because the light source of surround lighting is generally positioned at more than the visual angle central horizontal line in projection screen dead ahead, as sunshine, daylight lamp, therefore, when surround lighting irradiates from the oblique upper of projection screen, it can be blocked by spaced raised line 2, and sponge, thus surround lighting is irradiated less than the projection imaging layer 3 below raised line 2, or few partial illumination is to projection imaging layer 3, what surround lighting cannot or seldom be measured mixes (the mixing of this visual experience caused for light superposes with the throw light of projector equipment 4, light itself can not mix), and then the visual impression of throw light cannot be slackened, therefore, just it is more clear to be formed on the front side surface of described projection imaging layer 3, contrast is higher, projected picture (this " projected picture " same alleged herein " imaging picture " that brightness is brighter, its picture all referring to projector equipment 4 throw light and formed).When people normally watch projected picture, it is generally watched with the visual angle of slightly looking up or parallel vision.Thus, after the light of projected picture enters pupil, just can be formed at human eye the visual experience that picture picture is more clear, contrast is higher, brightness is brighter, and then present a very clear very perfectly picture to user.It should be noted that, shut out the light and light-absorbing effect although raised line 2 has, it can not cause the throw light from projector equipment 4 and significantly absorb abated effect.This is because projector equipment 4 is not usually higher than the most high rim of projection screen, the angle of its light projected and light-absorption layer makes to only have the light of few part to be blocked and to absorb, and the front side surface that most light still can arrive base material 1 carries out imaging.And human eye can not distinguish subtle difference like this, therefore, few some light is blocked can not affect to some extent on final the experienced visual pattern of user.User institute is sensitive is still even and the clear picture of continuous print, and compare and existing projection screen, user only can feel that projection screen imaging picture of the present utility model is more clear, contrast is higher, brightness is higher, and its image quality is better.And when reality uses, also by adjusting the putting position of projection screen and the angle that adjusts between raised line 2 and surround lighting and throw light, thus make it to play best projection effect.
The utility model by forming the raised line 2 of laterally spaced Absorbable rod light on base material 1, and projection imaging layer 3 is set between raised line 2, thus efficiently solve the interference that surround lighting causes projected picture, solve that projected picture is fuzzy, the problem such as distortion, picture turn white, substantially increase the sharpness of projected picture, contrast and brightness, improve image quality.
Although disclosed the utility model by above embodiment, but scope of the present utility model is not limited thereto, under the condition not departing from the utility model design, above each component can be replaced with the similar or equivalent element that art personnel understand.
