[0092] The application provides a multiple picture display screen (hereinafter referred to as a display screen), which can display different pictures at different positions at a preset distance, for example, a multi-storey shopping mall at a preset distance, so that the display screen can display the layout of the store on the floor and other information related to the floor. The user can obtain the information of the floor by finding the position of the window on the floor through the display screen, thereby avoiding the problem of getting lost because the user cannot find the display screen of the floor, and improving the shopping experience of the user.

[0093] Specifically, in some embodiments of the application, please refer to Figure 1As shown, the display screen comprises display groups 1 and light control groups 2, wherein the display groups 1 are capable of simultaneously emitting a plurality of sequentially arranged light beams, and the light control groups 2 are located on the path of the light beams to change the range angle and the exit angle of each light beam. The range angle is the angle between the upper boundary and the lower boundary of a light beam, for example Figure 2 the angle a in Figure a, Figure 2 the angle b in Figure b, and Figure 2 the angle θ in Figure c. The exit angle is the angle between the lower boundary of a light beam and the horizontal line, for example Figure 3 the angle γ in Figure a, Figure 3 the angle δ in Figure b, and Figure 3 the angle ε in Figure c. Please continue to refer to Figure 2 and Figure 3 As shown, by changing the exit angle of the light beams so that the light beams can only irradiate at the specified position at the preset distance, for example, the specified floor height range of a multi-storey building at the preset distance (for the convenience of description, the building in the following description is assumed to be located at the preset distance and have multiple floors). By changing the range angle of the light beams so that the light beams coincide with the specified range of the preset distance, for example, the height range of the specified floor of the building.

[0094] In more detail, as shown in Figure 4 , it is assumed that one of the display groups 1 on the display screen can simultaneously emit light beams of red, green and blue colors, and the building has three floors, wherein the exit angle of the light beams of red color is towards the first floor of the building, and the range angle of the light beams is the height range of the first floor, so that a person on the first floor looking at the display group 1 on the display screen will see the display group 1 emitting red light. The exit angle of the light beams of green color is towards the second floor of the building, and the range angle of the light beams is the height range of the second floor, so that a person on the second floor looking at the display group 1 on the display screen will see the display group 1 emitting green light. The exit angle of the light beams of blue color is towards the third floor of the building, and the range angle of the light beams is the height range of the third floor, so that a person on the third floor looking at the display group 1 on the display screen will see the display group 1 emitting blue light.

[0095] In the embodiments of the present application, the plurality of display groups 1 are arranged in an array, and the light control group 2 is located on the light exit side of the plurality of display groups. Under the action of the light control group 2, the illumination areas of the light beams at the same arrangement position on different display groups 1 at a preset distance are the same, and the illumination areas of the light beams at different arrangement positions on the same display group 1 at the preset distance are different. That is, all the light beams at the same arrangement position on the display groups 1 on the display screen are all illuminated in an area at the preset distance, and a picture can be seen in the area. Then, corresponding to the plurality of light beams of one display group 1, a plurality of different illumination areas, i.e. a plurality of different pictures, are formed. The adjacent two illumination areas have a spacing, and the spacing is greater than or equal to 0, so that there is no overlap between different pictures.

[0096] Please refer to Figure 5 As shown in the figure, still taking the example that one display group 1 can emit three light beams of different colors of red, green and blue in turn and the building has three floors. It is assumed that all the display groups 1 on the display screen can emit three light beams from top to bottom, which are upper light beams, middle light beams and lower light beams, respectively. The exit angle of the upper light beams of all the display groups 1 is towards the three floors of the building, and the illumination range of the range angle is the height range of the third floor. The exit angle of the middle light beams of all the display groups 1 is towards the two floors of the building, and the illumination range of the range angle is the height range of the second floor. The exit angle of the lower light beams of all the display groups 1 is towards the one floor of the building, and the illumination range of the range angle is the height range of the first floor. If the pattern composed of the upper light beams of all the display groups 1 on the display screen is a circle, the pattern composed of the middle light beams of all the display groups 1 is a triangle, and the pattern composed of the lower light beams of all the display groups 1 is a square, then a person located on the three floors of the building will see that the display screen displays a circle, a person located on the two floors of the building will see that the display screen displays a triangle, and a person located on the one floor of the building will see that the display screen displays a square.

[0097] Figures 6a to 6e When the display screen has five display groups 1 and the building has six floors, five floors, four floors, three floors and two floors respectively, the light ray diagram of the five display groups 1 on the display screen for displaying different numbers of pictures for different floors is shown in the figure. Taking Figure 6e and Figure 6d as examples, please refer to Figure 6e, the building includes two floors, and the display screen includes five display groups 1 from top to bottom, namely display group A, display group B, display group C, display group D, and display group E, the five display groups 1 can emit red and blue light beams, the emission angles of the red light beams of the five display groups 1 are all directed to the first floor, and the range angle of the red light beams is the height range of the first floor, and the emission angles of the blue light beams of the five display groups 1 are all directed to the second floor, and the range angle of the blue light beams is the height range of the second floor, then a person located at the first floor will see that the display screen displays a red screen, and a person located at the second floor will see that the display screen displays a blue screen. Please refer to Figure 6d , the building includes three floors, and the display screen includes five display groups 1 from top to bottom, namely display group A, display group B, display group C, display group D, and display group E, the five display groups 1 can emit red, blue and green light beams, the emission angles of the red light beams of the five display groups 1 are all directed to the first floor, and the range angle of the red light beams is the height range of the first floor; the emission angles of the blue light beams of the five display groups 1 are all directed to the second floor, and the range angle of the blue light beams is the height range of the second floor; the emission angles of the green light beams of the five display groups 1 are all directed to the third floor, and the range angle of the green light beams is the height range of the third floor, then a person located at the first floor will see that the display screen displays a red screen, a person located at the second floor will see that the display screen displays a blue screen, and a person located at the third floor will see that the display screen displays a green screen. By analogy. Figures 6a to 6e It can be known that if each floor of the building can see the corresponding picture on the display screen, then each display group 1 corresponding to the number of floors of the building should emit the same number of light beams.

[0098] In some embodiments of the present application, the display group 1 includes a plurality of three-color intersection imaging light sources 11 (hereinafter referred to as light sources 11) arranged in sequence, the light source 11 is a light source that presents the required color with red, green and blue three-color intersection, so that the color range of the light beam emitted by the light source 11 is wider to ensure that the color of the image presented by the display screen is more consistent with the actual situation. Optionally, the light source 11 is a light emitting chip, and one display group 1 is one pixel. The light source 11 corresponds to one light beam, one light source 11 can emit one light beam, and the display group 1 can emit as many light beams as the number of light sources included in the display group 1.

[0099] In some embodiments of the present application, one of the structures that can be implemented by the light control group 2 is a one-to-one corresponding structure with the display group 1, the light control group 2 includes a plurality of light collectors 20 corresponding to the light sources one by one, the light collectors 20 are arranged on the light emitting surface of the light sources 11, the light collection angles of different light collectors 20 are different, so that the range angles of different light beams are different, and different light collectors 20 allow the light beams to be emitted at different angles, so that the light beams are emitted at different angles. Thus, when the light beams emitted by the display group 1 pass through the light control group 2, the light sources 11 can display the specified color within the specified range at the preset distance, for example, looking at the light sources 11 from the third floor of the building, the light sources 11 emit red light, and looking at the light sources 11 from the second floor of the building, the light sources 11 emit green light.

[0100] Further, please refer to Figure 7a In some embodiments of the present application, the light collector 20 includes a lens 21 and a light blocking brim 22, wherein the lens 21 is located on the light emitting side of the light source 11, the light beam emitted by the light source 11 can enter the lens 21 and refract in the lens 21, so that the range angle of the light beam propagation can be changed when the light beam is emitted from the lens 21. The light blocking brim 22 is arranged on both sides of the lens 21, and covers the light source 11, so as to limit the light emitted by the light source 11 to pass through only within the range of the lens 21. In other words, the side of the light collector 20 facing the light source 11 is provided with a receiving groove 23, the light source 11 is located in the receiving groove 23, the groove walls on both sides of the receiving groove 23 are the light blocking brim 22 to block the propagation of the light emitted by the light source 11, and the groove wall of the receiving groove 23 facing the light source 11 is the lens 21, so that the light emitted by the light source 11 can only pass through the lens 21. The end of the light blocking brim 22 away from the light source 11 extends out of the lens 21 to limit the range angle of the light beam refracted by the lens 21. Figure 7a The figure shows the light emitting angle of the light beam emitted by the light source 11 within the range of the lens 21, and the range angle of the light beam finally emitted by the light source 11 under the action of the lens 21 and the light blocking brim 22 if there is no light blocking brim 22 and the lens 21. The display screen of the embodiment of the present application further includes a PCB 4, the display group 1 and the light control group 2 are arranged on the PCB 4, and the PCB 4 can transmit electric energy and signal instructions to the display group 1 to make the display group 1 perform the corresponding display task. Usually, the PCB 4 is a flat plate, the array of the display group 1 is multiple rows and multiple columns, and for this case, the emission angle of each light beam can be realized by setting the included angle between the center line of the lens 21 and the horizontal line. Therefore, please refer to Figure 9As shown in some embodiments of the present application, the first included angle between the center line of the lens 21 and the horizontal line is different for different light collecting members 20 on the same light control group 2. The lens 21 is located at different angle positions of the light source 11, and the light source 11 can only emit light from the lens. By changing the position of the first included angle, the emission angle of the light beam can be changed. If the multiple pictures displayed on the display screen are arranged in the height direction in sequence, the first angle of the light collecting member 20 at the same position of the light control group 2 in the same position of different rows in the array of the light control group 2 is different. For example, the first angle of the first light collecting member 20 on the light control group 2 in the first row and the third column is different from the first angle of the first light collecting member 20 on the light control group 2 in the tenth row and the third column.

[0101] Alternatively, please refer to Figure 8a As shown in some embodiments of the present application, the light collecting member 20 includes a lens 21, and the light source 11 is located at the light entrance surface of the lens 21. When the light beam emitted by the light source 11 passes through the lens 21, it can be refracted and reflected at the light entrance surface and the light exit surface, thereby changing the propagation path. The lens 21 is provided with a frosted surface, which can be regarded as being composed of a plurality of tiny planes arranged in random directions. When the light passes through the frosted surface, it is reflected by a large number of tiny planes to become diffuse reflection light. In other words, the frosted surface can disperse the light propagating along a specific path direction into light propagating in all directions. Thus, the light is prevented from continuing to propagate along the original path. By reasonably arranging the position of the frosted surface on the light exit surface or the light entrance surface of the lens 21, or on both the light exit surface and the light entrance surface, the light emitted by the light source 11 in an unwanted direction can be filtered out, and only the light propagating in the desired direction is left to form the final light beam. In this way, the emission angle of the light beam is changed. By changing the shape of the lens 21, the light beam is refracted at the light exit surface to change the range angle of the light beam and enhance the brightness of the light beam.

[0102] Alternatively, please refer to Figure 7b As shown in some embodiments of the present application, the light collecting member 20 includes a light-blocking brim 22, which has light-blocking property and can prevent light from passing through. The light source 11 is provided with a light-blocking brim 22 on both sides, and the sides of the two light-blocking brims 22 facing each other form a light propagation channel. The light propagation channel gradually widens from the light source 11 to a direction away from the light source 11. The angle of the light propagation channel is the brim angle, which limits the range angle of the light propagation, i.e. the range angle of the light beam can be changed by changing the size of the brim angle. The included angle between the lower boundary of the brim angle and the horizontal line determines the emission angle of the light beam, i.e. the emission angle.

[0103] In some embodiments of the present application, another structure that can be implemented by the light control group 2 is a structure corresponding to the entire display screen and located on the light exit side of the multiple display groups 1. For example:

[0104] Please refer to Figure 8b In some embodiments of the present application, another possible structure of the light control group 2 is that the light control group 2 is encapsulation glue coated on the display group, which not only can isolate the light source 11 from the outside world, protect the light source 11 and improve the heat dissipation of the light source 11, but also can change the angle and range of the light entering and exiting the encapsulation glue by changing the shape and thickness of the encapsulation glue at the position of the light source 11, so as to determine the exit angle and range angle of the light beam.

[0105] Alternatively, please refer to Figure 8b In still some embodiments of the present application, another possible structure of the light control group 2 is that the light control group 2 is a polaroid, which covers the light exit side of the display group array composed of multiple display groups. The polaroid is composed of multiple light transmission layers, and a light transmission structure with different shapes is arranged on one of the middle layers. The light transmission structure corresponds to the light source 11, and according to the refraction principle of light, the light is refracted at a specific angle, so as to determine the light exit angle and range angle of the light beam. Alternatively, multiple different micro polarizing filters corresponding to different light sources are arranged on one of the middle layers, only allowing light in a specific direction to pass through, and blocking or scattering light in other directions, so as to determine the light exit angle and range angle of the light beam.

[0106] The specific structure of the light control group is not limited in the present embodiment as long as it can change the exit angle and range angle of the light beam.

[0107] Please refer to Figure 10 As shown in the figure, the positions of the light beams 1, 2 and 3 on the display screen are different. The propagation range angle of the light beam 1 corresponding to the 5th floor is A, the propagation range angle of the light beam 2 corresponding to the 5th floor is B, and the propagation range angle of the light beam 3 corresponding to the 5th floor is C. The angles A, B and C are not very different, and the height of one floor is at least 2.5 meters, and the height of an adult is at least 1.4 meters. Even if the angles A, B and C are the same, the display range on the same floor is different. Since the difference is small and the display range includes the range of eyes of people with different heights, people with different heights on the 5th floor can see the picture corresponding to the 5th floor presented by the display screen. Figure 10 In the figure, if the light beams at different heights are all directed to the 5th floor, the difference between the exit angles of different light beams is large. For example, the exit angle of the light beam 1 is c, the exit angle of the light beam 2 is b, and the exit angle of the light beam 3 is a. Obviously, angle a is greater than angle b, which is greater than angle c. That is, if the light beams at different positions have a same irradiation area, the exit angle of the light beam can be changed, and the range angle of the light beam can be set to be the same.

[0108] Using the above principle, please refer to Figure 11 As shown, in some embodiments of the present application, the PCB board 4 is set to an arc board or a circular tube shape, and the array of display groups 1 is a single row array set along the length direction of the PCB board 4. In this case, it is equivalent to multiple display groups 1 being arranged at intervals along the length direction of the PCB board 4 to form a display bar that can simultaneously display multiple different colored lines. Multiple PCB boards 4 are arranged in sequence along the vertical direction, that is, the display bars are arranged in sequence along the vertical direction to form a display screen. Please refer to Figure 12 As shown, different PCB boards 4 are installed at different angles, meaning different display bars are installed at different angles. This ensures that light beams at the same position on display bars at different heights have different emission angles. For example, the emission angle of the light beam generated by the first light source 11 of the display group 1 in the third column of the display bar in the first row differs from the emission angle of the light beam generated by the first light source 11 of the display group 1 in the third column of the display bar in the tenth row. This ensures that the illumination areas of light beams generated by light sources 11 at the same position on display bars at different heights correspond to the same floor, thereby satisfying the requirement that the display screen can display different images on different floors. Since light beams at the same position on different display bars use the same range angle, the difference in illumination area on the same floor is negligible. Therefore, all light concentrators 20 can be set to have the same focusing angle. By setting the display bars at different installation angles, the requirement for different light beams to have different emission angles is met. This allows different light sources 11 to correspond to the same light concentrator 20, and the light control group 2 includes multiple identical light concentrators 20. The same screen requires display bars of the same specifications. By varying the installation angles of the display bars at different locations, the entire display screen can present different images on different floors. During production, multiple display bars of the same specifications can be produced, arranged in sequence, and the required display screen can be obtained by varying the installation angles of the display bars at different locations. This reduces manufacturing complexity, costs, and processing time.

[0109] In this embodiment, please refer to Figure 13 As shown, since the PCB board 4 is arc-shaped or tubular, the display group 1 is arranged circumferentially around the PCB board 4. Then, the first angles of the different focusing elements 20 of the light control group 2 corresponding to the display group 1 are different, so that the emission angles of the light sources 11 at different arrangement positions on the same display group 1 are different. By changing the vertical distance between two adjacent light sources 11 on the same display group 1, the emission angles of different light sources 11 on a display group 1 can be adjusted. This situation is for the same image on two different display screens corresponding to different floors of the same building, for example Figure 13 The vertical distance between two adjacent light sources 11 of the display group 1 on the display bar of Figure a is L, andFigure 13 In the middle b figure, the vertical distance between the two adjacent light sources 11 of the display group 1 on the display strip is F, and the values of L and F are different, then Figure 13 In the middle a figure, the display strip corresponding to the 1st floor, 3rd floor, 5th floor, 7th floor and 9th floor of the building can display the corresponding color lines, and Figure 13 In the middle b figure, the display strip corresponding to the 3rd floor, 4th floor, 5th floor, 6th floor and 7th floor of the same building displays the corresponding color lines. That is, by changing the vertical distance between the two adjacent light sources 11 of the display group 1 on the arc-shaped PCB board 4, the height position of the irradiation area of the same color line on the building can be changed.

[0110] It can be understood that the floor height of the building is usually consistent, and the distance between the display screen and the building is fixed. Different buildings have the same number of floors, and the number of pictures displayed by the display screen corresponds to the number of floors of the building. Alternatively, although the number of floors of different buildings is different, the number of pictures that need to be displayed by the display screen and the number of floors corresponding to different pictures are the same, for example, building A has 8 floors, building B has 5 floors, and display screen B needs to display different pictures corresponding to the 5 floors of building B, and display screen A needs to display different pictures corresponding to the 1st floor-5th floor of building A. In the above two cases, the same type of display strip can be used. For buildings in at least one of the following four cases: different floor heights; different numbers of pictures to be displayed; different floors corresponding to the same picture; and different distances between the display screen and the building, that is, for different buildings, the number of pictures required and the irradiation area (i.e. the field of view) of the picture can be flexibly made to meet the requirements of the display strip on the display group 1 of the display strip by changing the number of light sources 11, the distance between the two adjacent light sources 11, the distance between the two adjacent light sources 11 on the same display group 1, the structure of the light control group 2, and the structure of the light control group 2. 2 to meet the scene of different picture numbers and different field of view. In order to facilitate the production of the display screen and further reduce the cost, different series of display strips can be designed, and the difference between the display strips of different series includes at least one of the following cases: the number of light sources 11 included in the display group 1 is different; the vertical distance between the two adjacent light sources 11 is different; the vertical distance between the two adjacent light sources 11 on the same display group 1 is different; and the structure of the light control group 2 is different. So that the display strip becomes a series of standard parts, thereby realizing mass production, reducing manufacturing cost and manufacturing cycle. Of course, special requirements of customers can also be made to meet the requirements of the display strip.

[0111] In some embodiments of the present application, the display screen further comprises a controller, the display groups 1 are coupled to the controller, and the controller controls the different display groups 1 to emit a plurality of sequentially arranged light beams in the same time, and the plurality of sequentially arranged light beams are all in the preset color. Thus, the display screen simultaneously displays different pictures.

[0112] Generally, the size of the display screen capable of displaying pictures on a building is relatively large. In order to avoid that the display screen hinders the sightseeing view of the people in the building, in some embodiments of the present application, a plurality of hollow holes 3 arranged in an array are arranged on the PCB 4, and the array of the hollow holes 3 is arranged in a staggered manner with the array of the display groups 1. If the PCB 4 is a flat plate, please refer to Figure 14 , then the array of the hollow holes 3 is a plurality of rows and a plurality of columns. If the PCB 4 is an arc-shaped plate on the display strip, please refer to Figure 15 , then the array of the hollow holes 3 is a single row and a plurality of columns, and the hollow holes 3 and the display groups 1 are arranged alternately. Thus, the display screen is a transparent display screen, and the people in the building can see the scenery on the side of the display screen away from the building. The display screen also does not block the building, and the people on the side of the display screen away from the building can see the building through the display screen.

[0113] It can be understood that the more the number of the display groups 1 on one PCB 4, the better the picture effect displayed by the display screen, and thus the smaller the space occupied by the display groups 1. Compared with the different light sources 11 arranged in a circular shape, a hexagonal shape, a square shape, a triangular shape, etc. on the same display group 1, the different light sources 11 arranged sequentially to form a vertical line-shaped display group 1 or a horizontal line-shaped display group 1 occupy less space, which makes enough space on the PCB 4 to arrange the hollow holes 3. As shown in Figure 14 , in some embodiments of the present application, when the PCB 4 is a flat plate, the different light sources 11 on the display groups 1 are sequentially arranged in a vertical direction, so that the display groups 1 are in a vertical line shape, and one column of hollow holes 3 is arranged between two adjacent columns of the display groups 1, and no hollow hole 3 row is arranged between two adjacent rows of the display groups 1. Thus, more display groups 1 can be accommodated on the display screen to improve the display effect of the picture. Of course, in other embodiments, in order to improve the transparency of the display screen, one row of hollow holes 3 can also be arranged between two adjacent rows of the display groups 1. In other embodiments, the display groups 1 can also be arranged as horizontal line-shaped display groups 1 in which the plurality of light sources 11 are sequentially arranged in a horizontal line, as long as the picture requirements of the customer can be met, and the present embodiment does not make specific limitations in this regard.

[0114] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, but not limited to; although the present application is described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still be modified to the technical solutions recorded in the foregoing examples, or part of the technical features are replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
