LED element 12 in the 2nd LED module aligns with the second reference path 20 when rotated.In the preferred embodiment shown in Fig. 4, the low 1/2P of height of corresponding each LED element 11 in the residing aspect ratio of each LED element 12 the one LED module in the 2nd LED module 2W, every second reference path 20 forming when this makes to rotate is just in time positioned at the center of adjacent two the first reference path 10.
The example of display effect when Fig. 5 has shown the rotary display screen work in Fig. 4, by motor, drive rotating frame to pivot, pixel in display frame comprises the image retention D of a LED module formation and the image retention D' that the 2nd LED module forms, because of visual persistence phenomenon, two kinds of image retentions combine mutually, so pel spacing is reduced into P/2 in display frame.As can be seen here, adopt the mode in the utility model embodiment can significantly reduce pel spacing, thereby improved the ability (2 times that on vertical direction, resolution is traditional approach) of rotary display screen display of high resolution images.
Fig. 6 has shown a kind of complete spatial structure of rotary display screen of the present utility model, multiple LED elements 1 are vertically arranged and have been formed LED module 2, each LED module 2 is connected with central rotating shaft by a web member 3, and multiple LED module 1W～8W are parallel to each other and are evenly distributed on the common rotating frame that forms on rotation round.Above-mentioned rotating frame is arranged on stationary body 4, under the driving that is arranged on equally the motor 5 on stationary body 4, around central rotating shaft, rotates.In addition, in rotary display screen outside, be also provided with shell 6, be used for the each assembly in inside to carry out suitable protection.According to the preferred embodiment of Fig. 4, multiple LED module 1W～8W are divided into two groups, and two groups of LED module intervals arrange, and in LED module on the same group, the height of each LED element arrangements is identical, and element arrangements height difference on the same group not.In procedure for displaying, by control module, according to the distribution mode of LED module, picture to be shown is resolved into multiple parts, control the rotating speed of rotating frame simultaneously, make each LED module show in position the picture part that this module is responsible, finally by the image retention of multiple LED module rotation persistence of vision that obtain, jointly form complete cylinder display frame.
Fig. 7, Fig. 8 have further shown another preferred embodiment of the present utility model, wherein take three groups, arrange highly different LED module and are illustrated as example.In Fig. 7, the one LED module 1W, the 2nd LED module 2W and the 3rd LED module 3W interval arrange, LED element 11 in the one LED module 1W forms one with identical gap P and vertically arranges, downward from uppermost LED element 11, the height of the LED element 11 in arrangement is followed successively by H1, H2, H3, H4, H5 ... LED element 11 in multiple LED modules aligns with the first reference path 10 when rotated.LED element 12 in the 2nd LED module 2W also forms one with identical gap P and vertically arranges, downward from uppermost LED element 12, the height of the LED element 12 in arrangement is all different from a LED module, is followed successively by H1', H2', H3', H4', H5' ... LED element 12 in the 2nd LED module aligns with the second reference path 20 when rotated.LED element 13 in the 3rd LED module 3W also forms one with identical gap P and vertically arranges, downward from uppermost LED element 13, the height of the LED element 13 in arrangement is all different from a LED module and the 2nd LED module, is followed successively by H1 ", H2 ", H3 ", H4 ", H5 " ... the LED element 13 in the 3rd LED module aligns with the 3rd reference path 30 when rotated.In the preferred embodiment shown in Fig. 7, the low 1/3P of height of corresponding each LED element 11 in the residing aspect ratio of each LED element 12 the one LED module in the 2nd LED module 2W, in the 3rd LED module 3W, the residing height of each LED element 13 is again than the low 1/3P of height of each LED element 12 corresponding in the 2nd LED module, and three reference path 10,20,30 that form when this makes to rotate are just in time distributed between the gap P of adjacent LED element equally spacedly.
The example of display effect when Fig. 8 has shown the rotary display screen work in Fig. 7, by motor, drive rotating frame to pivot, pixel in display frame comprises image retention D, the image retention D' of the 2nd LED module formation and the image retention D of the 3rd LED module formation that a LED module forms "; because of visual persistence phenomenon; three kinds of image retentions combine mutually, so pel spacing is reduced into P/3 in display frame.As can be seen here, adopt the mode in the preferred embodiment can further reduce pel spacing, thereby improved the ability (3 times that on vertical direction, resolution is traditional approach) of rotary display screen display of high resolution images largelyr.
Above preferred embodiment has been described LED module and has been divided into two kinds of forms of arranging height or three kinds of arrangement height, relevant technical staff in the field will be understood that, above preferred embodiment is only as exemplary illustration, the technical solution of the utility model is obviously applicable to more kinds of patterns of arranging height, and aforementioned preferred embodiments should not regarded as restriction of the present utility model.In other preferred embodiments, LED module is divided into N group according to element arrangements height, and the LED module interval of each group arranges, and utilizes the high-resolution display frame of the overlapping acquisition of height official post image retention of LED element.More preferably, in each LED module, the interelement gap of LED equates, the arrangement difference in height of respectively organizing LED module also equates; Take N group as example, if interelement gap is P, each group is arranged height and is successively decreased with P/N.Certainly, gap equates and the even set-up mode of height equal difference is one of preferred implementation of the present utility model, in other preferred embodiment, if display precision is required to lower (such as in picture corner) in some region, obviously also can suitably increase interelement gap or increase the even directly LED element in clipped module etc. of difference in height, with the use amount that reduces LED element, reduce energy consumption and thermal value.Or, only in the region that needs high definition to show, increase the density of arranging (dwindle gap, reduced height poor or increase element etc.) of LED element.
The utility model provides a kind of improved rotary display screen, by changing the arrangement mode of LED element in LED module, interelement gap is filled up in the combination that makes full use of the different image retentions that formed by the difference in height of element, can effectively reduce the pel spacing of display frame, in the situation that not increasing LED number of elements, can show the image softer, resolution is higher, thereby the resolution that has solved rotary display screen is subject to the problem of element assemblage gap restriction.
Above-mentioned explanation illustrates and has described some preferred embodiments of the present utility model, but as previously mentioned, be to be understood that the utility model is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, modification and environment, and can, in utility model contemplated scope described herein, by technology or the knowledge of above-mentioned instruction or association area, change.And the change that those skilled in the art carry out and variation do not depart from spirit and scope of the present utility model, all should be in the protection domain of the utility model claims.
