Abstract
The present invention relates to an omnibearing display method and a device for realizing the method. With the function of visual persistence, the device of the present invention ensures that a display surface provided with a blanking device is driven to rotate at high speed by a rotary device, so that the display surface can circularly and repeatedly occur in the visual range of surrounding observers in the time limit of the visual persistence, and accordingly, the observers in any position around the display surface can always see the visual effect that the display surface just faces the observers, namely the omnibearing display effect.
Description
The present invention relates to a kind of display technique, particularly a kind of device that utilizes the persistence of vision effect to obtain method with this method of realization of comprehensive display effect constantly.
In the prior art, any picture displayed (some given side and dynamic menu of comprising plane picture, stereoscopic picture plane, three-dimensional thing of needing, below be referred to as display surface) all can only in certain scope, be observed, even display surface is very clear, also can only be observed clear in the certain angle scope of display surface.And can not more can not see it in its side at its back side, even in its front, also can reduce observing effect because of the inclination at visual angle.
For overcoming this defective, in actual applications, often make several identical display surfaces, in a big way in the face of several directions are evenly arranged, so that it is observed.For example, place information display screen, clock or billboard on hall or the high-lager building, adopt this method to reach the effect of broadening one's vision exactly, but the simple combination of a plurality of display surfaces of this employing still can't make the observer who is in the optional position all obtain the visual effect of observing over against display surface.
In the prior art, people also once utilized the persistence of vision effect, take continuously by human eye, and the still frame that gradually changes according to certain rules produces TV, film or animation effect, but the observer also can not see this effect at an arbitrary position.
The applicant's a utility model patent 91211525.4 has formerly disclosed a kind of comprehensive display device, this device utilizes people's persistence of vision effect, by making one to have the display screen of blanker with rotational speed rotation greater than 16 cycle per seconds, thereby make the observer of optional position around the display screen can both see the content of this display screen, realize comprehensive demonstration.But through further discovering, as minimum requirements, display screen must require too high with the rotational speed rotation greater than 16 cycle per seconds, will certainly go up to specific design, manufacture craft and the use of this device and propose higher requirement, is unfavorable for implementing.
The objective of the invention is: on the basis of the applicant's utility model formerly 91211525.4, for realizing comprehensive demonstration, a kind of more rational and method of being more convenient for implementing is provided, and the device of this method of realization, utilize the persistence of vision effect, by making the display surface that needs to observe in the time limit of persistence of vision, circulation repeats in the observer's eye around it, thereby obtains the visual effect of comprehensive demonstration constantly.
Technical solution of the present invention is:
A kind of omnibearing display method, the display screen that makes the place ahead of its display surface have blanker rotates around a vertical axis, or simultaneously around horizontal axis rotation or horizontal tilt vibration, and make its rotating speed V around this vertical axis rotation
1Greater than 12 cycle per seconds, V
1Preferably be taken as the 20-60 cycle per second, or the rotating speed V that rotates around this horizontal axis simultaneously
2=V
1* 360 °/α or around the number of times of horizontal axis pitch vibration
In various: α serve as reasons arbitrary image cell that this blanker cuts apart display surface at display surface in this vertical axis rotary course, in observer's eye from disappearance occurring, the circumferential angle of the level that display screen turned over.β and γ are respectively the elevation angle and the angle of depression of display screen around the horizontal axis vibration.
In technical scheme of the present invention, display surface is around the rotation of this vertical axis, or simultaneously around this horizontal axis rotation or horizontal tilt vibration, thus circulate constantly, again and again inswept one be the 360 ° of ring weeks or the spheric region at center with the display surface.And before display surface, have and its blanker that rotates synchronously, the effect of blanker is the restriction range of observation, its objective is and make the display surface can only be when the position that rotates to over against the observer, could the observed person see, and after display surface continues to turn over a small angle forward, because the effect of blanker, the image of display surface promptly disappear from observer's eye, thus avoided display surface variant when rotated towards the mutual superposition of image.Because persistence of vision effect, the impression of this display surface also will keep an of short duration moment, and when this impression does not disappear as yet, display surface rotates back into observer's front again, and seen again, go round and begin again, can make the observers of in one 360 ° around this display surface ring weeks or spheric region optional position by the acting in conjunction with blanker of rotatablely moving, all seeing the visual effect of display surface over against oneself all the time, also is comprehensive display effect.Display surface this in fact discontinuous observed person under show state see, therefore obtain the luminous flux of enough display surfaces for the optic nerve that makes the observer, guarantee vision response, so that it clearly sees display surface, therefore display surface is preferably bright, and it can be that self is shinny or be illuminated.If display screen self is shinny, display screen will generate heat; If display surface is thrown light on, light source and display screen all can generate heat, and therefore also must cool off light source, display screen, and be for example air-cooled.
In actual applications, realize that around a vertical axis and a horizontal axis rotation difficulty is bigger simultaneously owing to make display screen, under general occasion, the omnibearing display method that more suitable enforcement display screen only rotates around vertical axis, can make the observer under the situation that the height of its present position and display surface is more or less the same, still can obtain display surface all the time over against oneself visual effect.
According to purpose of the present invention, also provide a kind of comprehensive display device of implementing said method.This device comprises: a pedestal, one display screen, be arranged on the place ahead of display surface of this display screen and a blanker that fixes with this display screen, one is installed on the vertical rotating driving device on the pedestal, this vertical rotating driving device is connected with this display screen, it is characterized in that under the driving of this vertical rotating driving device, this display screen is with the speed V greater than 12 cycle per seconds
1Rotate around a vertical axis.
In said apparatus, also can be set as and make display screen, thereby constitute multi-form and comprehensive display device effect simultaneously around the rotation of a vertical axis and a horizontal axis or in this Z-axis rotation, making pitch vibration around a horizontal axis.
For simultaneously around the rotation of a vertical axis and a horizontal axis, or at the display screen of in this Z-axis rotation, making pitch vibration around a horizontal axis, the blanker that is adopted can be by opaque, the thin slice of opaque low key tone is perpendicular to display surface and the different shape that intersect to constitute triangle for example, rectangle, the network of polygon etc. or also by opaque, the thin wall tubule of opaque low key tone is perpendicular to the cellular structure of the intensive composition of display surface.
Around the display screen of vertical axis rotation, the blanker that is adopted can be by opaque for only, and the thin slice of opaque low key tone is arranged a screen of formation parallel to each other perpendicular to display surface and vertical.Or between each thin slice of described screen, further fill and fixed refraction near the light guide plate that transparent material constituted of air index.
The effect of blanker repeats no more as previously mentioned.
Because no matter display screen rotate or rotate around horizontal axis around vertical axis, all can produce very big windage, so can add member such as containing display screen in above-mentioned whirligig, its profile is the transparent wind resistance housing of rotationally symmetrical surf, to reduce windage.
In addition, for simultaneously around the display screen of vertical axis and horizontal axis rotation, because position up and down can alternately appear in display screen, occur making progress and causing the erect image of display surface in observer's eye and the stack of inverted image to upper/lower positions for fear of replacing because of display screen, also must add one on the whirligig not around the rotation of this horizontal axis, look plate, be in when upper/lower positions (inverted image) with convenient display screen with parallel the exempting from of this horizontal axis, its display surface is sheltered from, and the observed person does not see.
Owing to wish that the display surface of display screen becomes clear, can be that display screen self is shinny, electric light source also can be set to throw light on to it, simultaneously in order to prevent the heating of this electric light source and display screen, can add cooling device again, air cooling equipment for example, or other cooling devices cool off this electric light source and display screen.
Advantage of the present invention is: effective indication range is wide, and the observers that spend the optional position in ring week zone in the spheric region or 360 that with the display surface is the center all can obtain over against the visual effect of display surface observation.In addition, compare, owing to minimum rotational speed V display screen with the applicant's utility model formerly
1Be reduced to 12 cycle per seconds from 16 cycle per seconds, Design of device, manufacture craft and request for utilization have all been reduced widely.Because the increase of display screen centrifugal force when rotated is directly proportional with the quadratic power of rotational speed, if rotating speed has been reduced to 12 cycle per seconds from 16 cycle per seconds, though only reduced by 1/4th, centrifugal force has reduced nearly one times (16
2/ 12
2≈ 1.78).Therefore, under the condition of same technology, structure and material, the area of display surface can increase to original 1.78
2Doubly.Like this, technology of the present invention just has bigger range of application, and can reduce cost of manufacture.
Below in conjunction with accompanying drawing, describe most preferred embodiment of the present invention in detail, so that other purposes of the present invention, feature and advantage are able to more clear.Wherein:
