Abstract
The invention provides a narrow-perspective micro-bead screen used for personal projection-watching, comprising a micro-bead reflective material layer 1, a bonding layer 2 and a screen substrate 3; the narrow-perspective micro-bead screen is characterized in that the micro-bead reflective material layer 1 is made of glass micro-beads with the refractive index of 1.9-2.5; the micro-bead reflective material layer 1 is attached to the screen substrate 3 by the bonding layer 2; and the screen substrate 3 can be made of hard plane material 4 or coiling material 5 or flexible material 6 according to the requirements. When the micro-bead screen is used for watching the pictures with low brightness projected by an individual projector, the projection pictures on the screen can be seen from a position close to the projector, the brightness thereof is extremely high and the color thereof is extremely flamboyant, the effect is far better than that of normal screen, thus marking up the shortages of low brightness of the individual projector.
Description
Technical field
The present invention relates to a kind of screen, be specifically related to a kind of narrow viewing angle micro-bead curtain for personal projection-viewing.
Background technology
Along with the continuous progress of digital projection technique, the range of application of projector more and more widely develops to individual application from scientific research and education, business office field just gradually.Occurred on the market being used for the exclusive projector product that the individual watches projection, as ultra-thin portable translucent machine, desktop minitype projection machine, pocket mobile phone projectors or the like.But, find that in actual applications these only are subjected to the little restriction of machine volume for the exclusive projector that the individual watches owing to light source power, ubiquity the low weak point of projected picture brightness, if when projection, adopt common reflection screen, the weak point of its existence will can not get overcoming, thereby can only influence viewing effect by the reduced projection picture.Therefore, this should have a kind of supporting individual to watch the special-purpose screen of projection only for individual exclusive projector of watching in use, remedies the low weak point of individual exclusive projector brightness.
Summary of the invention
In order to overcome the existing low weak point of individual exclusive projector's projected picture brightness, wide more according to the glass microballoon viewing angle of screen, reflecting brightness is low more; The visual angle is narrow more, the ultimate principle that reflecting brightness is high more, the invention provides a kind of and individual exclusive projector supporting, be specifically designed to the narrow visual angle micro-bead curtain that the individual watches projection.This narrow visual angle micro-bead curtain adopts the microballon reflectorized material that warning safe is used on fire fighter's working cloth to make, the characteristics of this microballon reflectorized material are: as ray cast during to this material, if watch the angle between angle and the angle of incidence of light more little, watch the reflection ray on this material just strong more; If angle between the two is big more, reflection ray is then weak more, and when the incident angle of light changes within the specific limits, also has same reflecting effect.This narrow visual angle microballon reflectorized material that can go and return without undue delay and reflect light is mainly used in the warning mark on personnel's working cloth such as fire-fighting, road, environmental protection at present, so that found with the protection personal safety by light-illuminating easily when working at night.
This microballon reflectorized material that is used for warning on the working cloth is particularly suitable for the making narrow viewing angle micro-bead curtain for personal projection-viewing of migrating now, not only draws materials convenient but also can produce beyond thought viewing effect.When the individual exclusive projector of low-light level when projection is carried out in this screen, as long as the beholder is sitting near on the position of projector, very bright gorgeous projected picture in this screen that will see, thereby successfully solved individual exclusive projector and do not had supporting special-purpose screen, the weak point that projected picture brightness is low.
The solution of the present invention is: a kind of narrow viewing angle micro-bead curtain for personal projection-viewing, include microballon reflective material layer 1, adhesive layer 2 and screen bottom 3, it is characterized in that microballon reflective material layer 1 employing refractive index is 1.9～2.5 glass microballoon making, when incident angle is that 5 °～40 °, view angle are 12 ' time, the retro-reflecting coefficient of microballon reflective material layer 1 is 600～400; When incident angle is that 5 °～40 °, view angle are 20 ' time, the retro-reflecting coefficient of microballon reflective material layer 1 is 500～300; When incident angle be 5 °～40 °, when view angle is 1 °, the retro-reflecting coefficient of microballon reflective material layer 1 is 60～25; When incident angle is that 5 °～40 °, view angle are 1 ° of 30 ' time, the retro-reflecting coefficient of microballon reflective material layer 1 is 50～15, can see that thus view angle is more little, and the light reflection is strong more.For the ease of using this narrow viewing angle micro-bead curtain for personal projection-viewing, microballon reflective material layer 1 sticks on the screen bottom 3 by adhesive layer 2, screen bottom 3 can be as required rigid planar material 4, also can be circumnutate material 5, can also be flexible material 6.For the ease of hanging this narrow viewing angle micro-bead curtain for personal projection-viewing, the perforation of installation 7 is arranged at screen four jiaos.
Advantage of the present invention is: utilize the microballon reflectorized material that warning safe is used on existing fire fighter's working cloth, making narrow viewing angle micro-bead curtain for personal projection-viewing is a kind of invention of migrating, and not only drawing materials makes things convenient for low cost of manufacture; And adopt this screen to watch when throwing picture, and as long as be sitting in, will see that the picture in the screen is bright especially beautiful in colour near on the projector position, have beyond thought appreciation effect.By this distinguished narrow visual angle micro-bead curtain, can remedy the low weak point of individual exclusive projector brightness fully, boundless popularizing application prospect will be arranged.

Fig. 1 is that front view 2 of the present invention is side view A of the present invention, B, C
Among the figure 1, microballon reflective material layer 2, adhesive layer 3, screen bottom 4, rigid planar material 5, the material 6 that circumnutates, flexible material 7, perforation
A kind of narrow viewing angle micro-bead curtain for personal projection-viewing, include microballon reflective material layer 1, adhesive layer 2 and screen bottom 3, it is characterized in that microballon reflective material layer 1 employing refractive index is 1.92 glass microballoon making, its retro-reflecting coefficient: when incidence angle is that 5 °, view angle are 12 ' time, the retro-reflecting coefficient of microballon reflective material layer 1 is 490; When incidence angle is that 5 °, view angle are 20 ' time, the retro-reflecting coefficient of microballon reflective material layer 1 is 360; When incidence angle be 5 °, when view angle is 1 °, the retro-reflecting coefficient of microballon reflective material layer 1 is 45; When incidence angle is that 5 °, view angle are 1 ° of 30 ' time, the retro-reflecting coefficient of microballon reflective material layer 1 is 30. For the ease of using this narrow viewing angle micro-bead curtain for personal projection-viewing, microballon reflective material layer 1 sticks on the screen bottom 3 by adhesive layer 2, screen bottom 3 can be as required rigid planar material 4, also can be circumnutate material 5, can also be flexible material 6. For the ease of hanging fixing this narrow viewing angle micro-bead curtain for personal projection-viewing, at screen four jiaos the perforation of installation 7 is arranged.
