Description

360 ° of sphere display screens of a kind of LED

Technical field

The utility model relates to a kind of LED display, 360 ° of sphere display screens of especially a kind of LED.

Background technology

Traditional LED display is flat-faced screen mostly, it adaptable across the station, harbour or airport etc., be used for showing by bus information by ship; Also be applied to highway now, be used for showing driving variable information or the like.This planar LED display screen, though have the reliability height, use that group's life is long, cost performance is high and advantage such as use cost is low,, it is single in display format, can't satisfy the diversified demonstration needs of people.For this reason, people have invented spherical display screen, are used for addressing the above problem; Disclose a kind of all-colour LED sphere display screen like Chinese patent document CN201429939, comprised the spheroid skeleton, sphere is formed by some led module splicings in said spheroid skeleton outside; Trapezoidal (being similar to) and triangle that the display part of the whole spheroid of said spherical display screen has some groups of shapes not wait are spliced; During by suitable angle cutting (such as 6 degree), whole spheroid has 1800 splicings to accomplish, and is divided into 120 groups; Every group of area that is not waited by 15 block sizes formed, and 14 trapezoidal adds a triangle; Arrange as required the LED luminotron is installed.It can be fixed on the wall, on the ground and be suspended in the air, can under the cooperation of computing machine, make various dynamic images and show.For another example; Chinese patent document CN201812452U discloses a kind of spherical LED display device; Wherein, This dome shape LED display device shows modules by a plurality of unit LEDs and is used to connect the web member that each unit LEDs shows module and forms that said dome shape LED shows that module is the ball clack shape module that obtains after spheroid launches through warp and parallel, and it can realize that the beholder can the interior purpose of multi angle view demonstration.

; Above-mentioned two spherical display screen all is that the warp and weft with spheroid is a cut-off rule, and whole sphere is divided into little display module with different size and shape; Constitute whole sphere by these modules again; This spherical display screen, not only the making of module and installation quite bother, and aspect display driver, adopt and take out type of drive a little; In addition, because the size of each display module and different,, just can repair, cause the inconvenient problem of maintenance if when certain piece display module damages, can only use corresponding module to replace.

Embodiment

See also Fig. 1 to Fig. 3; What Fig. 1 to Fig. 3 disclosed is 360 ° of sphere display screens of a kind of LED; Comprise spherical skeleton 1; On said spherical skeleton 1 surface, be provided with the shape arc-surface display screen of being made up of some LED module splicings 2 identical with size, all arc-surface display screens 2 constitute a ball screen 10.Said ball screen 10 is arranged on the inside surface of said spherical skeleton 1 or on the outside surface; And the resolution of said each arc-surface display screen 2 is identical, and like this, the shape of arc-surface display screen 2, size and resolution are identical; Can guarantee the versatility of each arc-surface display screen 2; When changing image content, only need to change the storage card of video source, just can change displaying contents easily; Have highly versatile and characteristics easy to maintenance.

In the utility model, said arc display screen 2 preferably is 6 with establishing, and respectively with 6 corresponding connections of video source, each arc display screen 2 carries out point-to-point demonstration with video source.In this case, the resolution of said arc display screen 2 is identical, preferably 1152px*1152px or 1600px*1600px.

In order to keep in repair the convenience with part exchanging, each said arc display screen 2 is that the elementary cell 21 by 4 same structures is spliced, and half-twist, 180 ° and 270 ° form arc display screens 2 to elementary cell 21 respectively around central point.Each said elementary cell 21 is made up of 6-80 casing, in each casing, is provided with the LED module that is made up of several LED lamps.LED lamp on each LED module is counted identical.

In order to dispel the heat, on said LED module, be provided with louvre, the area of said louvre will cover more than 10% of entire module area.In the utility model, the scan mode of said LED module is 1/8 to line by line scan.

See also Fig. 4, Fig. 4 is an example structure synoptic diagram of the built-in arc-surface display screen of the utility model.When said ball screen 10 is arranged on the inside surface of said spherical skeleton 1, in said spherical skeleton 1, be provided with transparent grandstand 3, said transparent grandstand 3 is fixedly connected with said spherical skeleton 1.

Be example with the spherical display screen of making 10 meters of internal diameters below, the manufacturing process of each several part is described.

At first the surface (inside surface or outside surface) with spherical skeleton 1 is divided into six five equilibriums, and promptly six arc-surface display screens 2 are divided into 4 five equilibriums again with each arc-surface display screen 2 again, i.e. 24 elementary cells 21.

Each elementary cell 21 comprises 16 casings (casing can be selected) again between 6-80; Each casing is formed 144 circuit units by high H3*D3 module unit plate; So whole ball face 10 1 has 3456 circuit units, 384 casings, 24 elementary cells 21; The ball surface of the elementary cell 21 with 1/24th carries out respectively around the point in the lower left corner that 90 degree duplicate, 180 degree duplicate, 270 degree duplicate and can obtain arc display screen 2.Make remaining five face respectively by this way, these six faces are combined into a spheroid get final product.

1/24 elementary cell 21 is by 144 quadrilateral built-up circuit cell boards that the length of side is not of uniform size.The maximum flat shape quadrilateral length of side is: 331.77mm x 331.489mm x 331.489mm x 331.77mm.Minimum parallel 4 each length of side of limit shape are respectively: 271.91mm x275.145mm x 275.146mm x 281.91mm.

The LED lamp of each LED module is counted all consistent, and each LED module is a plane, and resolution is the 48px*48px point, does not take out a driving, realizes point-to-point control.Because each LED module is not of uniform size, so the spacing of lamp and lamp is also different, minimum is 5.22865mm, and maximum is 6.54425mm.Adopt the soldering copper post to come to fix around the LED module with casing.Logical sound holes (also being louvre) is opened on LED module plate face; Each LED module primary design is 169 (it is respectively 13 that length is followed wide); Aperture 1.3mm, the LED lamp bank of each LED module is listed as all not specification, comes to confirm the coordinate of each pixel on the every LED module as required.

Acting the leading role the Room in the utility model is global formula structure; Screen is 360 degree integral spherical, and the visitor stand in the transparent grandstand 3 in ball curtain middle level during film projection, and transparent grandstand 3 adopts the panorama type transparent design; Middle no any support lets spectators be under the state high up in the air fully.360 degree whole world curtains let the people place oneself in the midst of another space-time seemingly as firmament the earth, experience impayable novelty and stimulation.
