Detailed Description
In order to make the technical problems solved, the technical solutions adopted and the technical effects achieved by the present invention clearer, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings.
As shown in fig. 1, the present embodiment provides an annular transparent screen, which includes an annular screen 1 and a driving mechanism 2, wherein the driving mechanism 2 is connected to the annular screen 1 for driving the annular screen 1 to rotate around its axis. The driving structure comprises a power source and a central shaft 21, wherein the central shaft 21 is arranged inside the annular screen 1 and is coincided with the axis of the annular screen 1. The power source is in transmission connection with the central shaft 21, and the central shaft 21 is connected with the annular screen 1, so that the annular screen 1 is driven to rotate by driving the central shaft 21 to rotate.
In this embodiment, the annular screen 1 has a large-area hollow area in a static state, so that the annular screen 1 has high transparency, and a viewer can see the scenery behind the screen through the hollow area on the annular screen 1. When the device is actually viewed, the annular screen 1 rotates around the axis of the annular screen 1 under the driving of the driving mechanism 2, a scanning surface is formed by switching line images displayed by the annular screen 1, and continuous and clear image display is realized by utilizing the human visual persistence effect.
Specifically, as shown in fig. 2, the ring screen 1 includes a plurality of poles 11 and diagonal braces 12. The lamp post 11 is a strip plate-shaped structure, the lamp post 11 is vertically arranged, and a plurality of lamp posts 11 are arranged at intervals around the circumference of the central shaft 21 to form an annular display area. The annular screen 1 is divided into a plurality of vertical areas by the plurality of lamp poles 11, and the display content of each vertical area is adjusted according to the position of the vertical area so as to form an annular complete image.
In this embodiment, connect a plurality of lamp poles 11 through the bracing 12 that inclines of X type and form annular screen 1 to one side, bracing 12's stable in structure to one side is favorable to improving the mechanics degree of consistency of annular screen 1, and installation, preparation are easy, and annular screen 1's whole anti deformability is strong and stability is good. This annular screen 1 has great fretwork region between two adjacent lamp poles 11 when static for annular screen 1 just has higher transparency at static state, and when annular screen 1 rotated the display screen, the sight shadow person can see through the fretwork region on the annular screen 1 and see the scenery behind the screen, realizes transparent display effect.
In addition, the size of the display area of the annular transparent screen is determined by the length of the lamp post 11 and the diameter of the annular screen 1. Through the length of adjustment lamp pole 11 or the diameter of annular screen 1, can adjust display area's size in a flexible way for display area can adjust according to actual need, solves the limited problem of display area among the prior art.
For making the length adjustment of lamp pole 11 more nimble, as shown in fig. 4, every lamp pole 11 can include a plurality of lamp plates 111, and a plurality of lamp plates 111 form lamp pole 11 along vertical direction concatenation. Each lamp post 11 may be provided with a plurality of controllers 112, each controller 112 is provided with a data processing unit and a laser detector, and each controller 112 may control a plurality of lamp panels 111. The lamp panel 111 includes a substrate, and a light emitting unit 1111, an optical module and a Printed Circuit Board (PCB) for driving the IC, which are disposed on the substrate, wherein the PCB is provided with an input/output port for data and a power supply module. Two adjacent lamp poles 11 are connected through a plurality of diagonal braces 12, so that the annular screen 1 is formed. Alternatively, the light emitting unit 1111 may be inside the lamp post 11, or may be outside the lamp post 11.
Alternatively, the light emitting unit 1111 may be an LED lamp or a vector light emitting unit. With respect to larger display dimensions, for example, when the light source occupies less than one-tenth of the display area, as shown in fig. 5, the vector pixels (ansetropicpixels) can be approximately regarded as light sources emitting light at a point, and most of the light beams emitted to the space are narrow beams, namely, the light beam boundaries with the light intensity falling to 50% of the maximum light intensity of the light beam, and the light sources are circular, and the minimum spatial spherical angle capable of including all the boundaries is less than 10 degrees. The vector pixels can support the projection of the narrow light beams in not less than 100 distinguishable directions, and can simultaneously emit light beams in two or more directions, and the brightness of the emitted light beams can support at least 16 steps of adjustability. The vector light emitting unit in this embodiment may be an optical device that satisfies the above conditions, and the specific structure of the vector light emitting unit is not limited in this embodiment.
In this embodiment, the light emitting units 1111 may be vector light emitting units, and according to characteristics of light beams emitted by the vector light emitting units, the light emitting angle of each light emitting unit 1111 may be adjusted when the radial position of the lamp post 11 is deviated, so as to obtain a better display effect. For example, taking a certain light beam emitted by the light-emitting unit 1111 as an example, when the light pole 11 is located at a standard radial position, the light-emitting unit 1111 will emit at a standard angle to obtain a standard light beam; when the radial position of the lamp post 11 has an error, since the lamp post 11 will be deflected to the inside or outside of the ring screen 1, if the light beam emitted by the light emitting unit 1111 at the standard angle is not coincident with the standard light beam, the display effect will be affected. At this time, the intersection point of the standard light beam emitted by the light emitting unit 1111 at the standard radial position and the cylindrical surface where the light emitting unit 1111 is actually located and the emission direction of the standard light beam at the intersection point position can be calculated, so that the light emitting unit 1111 is controlled to emit a light beam in the calculated emission direction of the standard light beam when passing through the intersection point position, and the influence of the radial position error of the lamp post 11 on the display effect is compensated.
In order to make light-emitting unit 1111 of a plurality of lamp panels 111 be located same cylinder face, a plurality of lamp panels 111 in every lamp pole 11 are located the coplanar, and the terminal surface of adjacent lamp panel 111 aligns and the butt. In order to connect a plurality of lamp panels 111, the number of the diagonal braces 12 between two adjacent lamp poles 11 may be the same as the number of the lamp panels 111 in each lamp pole 11. Specifically, four vertex angle positions of each lamp panel 111 are provided with first screw holes respectively. And two ends of each connecting rod 121 in the inclined strut 12 are respectively provided with a lug 123, and two second threaded holes are vertically arranged on the lugs 123. Two second screw holes on every lug 123 correspond and align with the first screw hole on two adjacent lamp plates 111 to make two lamp plates 111 of splicing along vertical direction can be connected to every lug 123. In two adjacent diagonal braces 12, two lugs 123 at the bottom of the upper diagonal brace 12 are respectively overlapped with two lugs 123 at the top of the lower diagonal brace 12. Optionally, the diagonal bracing 12 can be a thin plate structure made of materials such as aluminum or steel, so that the diagonal bracing 12 has certain elasticity, and the annular screen 1 has certain flexibility, which is beneficial to improving the deformation resistance of the annular screen 1, and when the annular screen 1 rotates, the flexible annular screen 1 can automatically adjust the cylindricity of the annular screen 1 according to the centrifugal force, so that the annular screen 1 is sufficiently round and stable.
In this embodiment, the area that is used for the lamp pole 11 of demonstration in the annular screen 1 is little for the optical transparency of annular screen 1 is high, simultaneously, because the display area of lamp pole 11 is little, and the reflection of light area that corresponds is also little, and the surface of lamp pole 11 can adopt the design of blacking on this basis, thereby lamp pole 11 can reduce the luminance loss to the reflection of light, makes annular screen 1 have higher contrast, and the image and the color that show are more clear.
Because the light that is provided with the position of bracing 12 to one side in the annular screen 1 will be sheltered from, shelters from the area and is big more, and the luminance of this position department is darker more, shelters from the area and varies and will lead to annular screen 1 to appear the alternate problem of light and shade, influences annular screen 1's display effect.

To simplify the structure of the stay 12, the shielding portion 122 may be a sheet structure integrally formed with the link 121. Alternatively, the shape of the shielding portion 122 may be a triangle, or may be other shapes as long as the areas of the diagonal braces 12 in the unit height area are ensured to be equal.
