Description

Technical Field

[0001] The present invention relates to the technical field of LED displays, and more specifically, to an LED display device and a method for determining the arrangement manner of its lamp beads. Background Art

[0002] The currently popular XR virtual shooting technology is a real-time virtual-real synthesis technology that replaces the traditional green screen keying technology and has wide applications in the fields of radio and television and stage live broadcasts. This solution can significantly improve the synthesis effect of people and virtual backgrounds, avoid the phenomenon of green spillage and the sense of hollowness generated by actors performing in a pure green environment. Additionally, by changing the perspective effect of the real-time rendered virtual scene to accurately interact with the displacement of the camera, the realism of the captured image is further enhanced.

[0003] As Figure 1 shown, such an XR virtual shooting LED display screen includes two vertical screens and one floor screen that intersect pairwise. A plurality of LED lamp beads are arranged in an array on the surface of each screen. Each LED lamp bead can be regarded as a display pixel, and each display pixel contains red, green, and blue three primary color chips. The mixed light of the three primary color chips can display a variety of colors.

[0004] As Figure 2 shown, the light-emitting direction of the LED lamp bead is in a conical shape with the normal direction of the front surface of the lamp as the axis. Since each display pixel has a certain physical volume, when the viewer or the shooting device is at a viewing point position at a large angle relative to the display pixel, the primary color chips closer to the viewer or the shooting device will block the light emitted by the other two primary color chips, thereby resulting in a color deviation phenomenon and affecting the display effect. That is, the closer to the normal position, the more uniform the color mixing; at a large angle deviating from the normal direction, the mixed light ability of the three primary colors of the LED decreases, and the color deviates.

[0005] As Figure 3 shown, the three primary color chips in the display pixel on the LED display device in the related art are generally arranged along the length direction parallel to the screen or the width direction parallel to the screen. Specifically, Figure 3 the three primary color chips of the display pixel on the second screen body 2 in [[ ]] are arranged in the vertical direction, and the three primary color chips of the display pixel on the first screen body 1 are arranged in the horizontal direction perpendicular to the docking side of the first screen body 1 and the second screen body 2. When viewing the image displayed by the LED display device at a position directly opposite to the second screen body 2, the color mixing of the three primary color chips of the display pixel on the second screen body 2 does not affect each other. However, the color mixing of the three primary color chips of the display pixel on the first screen body 1 is severely affected, thereby resulting in a large color difference at the docking side of the first screen body 1 and the second screen body 2. Correspondingly, Figure 1 a large color difference also appears at the position A in [[ ]]. Summary of the Invention

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0041] Figure 4 and Figure 5 FIG. 1 shows a schematic structural diagram of Embodiment 1 of an LED display device according to the present application. Among them, the LED display device includes: a first screen body 10, a second screen body 20, a plurality of first light-emitting diodes 30 and a plurality of second light-emitting diodes 40. Among them, the second screen body 20 intersects with the first screen body 10; the plurality of first light-emitting diodes 30 are arranged in an array on the front surface of the first screen body 10, and there is a first included angle θ1 between the setting direction of each first light-emitting diode 30 and the setting direction of the first screen body 10; the plurality of second light-emitting diodes 40 are arranged in an array on the front surface of the second screen body 20, and there is a second included angle θ2 between the setting direction of each second light-emitting diode 40 and the setting direction of the second screen body 20.

[0042] Applying the technical solution of this embodiment, multiple first light beads 30 on the first screen body 10 are inclined relative to the first screen body 10 at a first included angle θ1, and multiple second light beads 40 on the second screen body 20 are inclined relative to the second screen body 20 at a second included angle θ2. In this way, it can effectively avoid light blocking between the primary color chips (i.e., the first red light chip 31, the first green light chip 32, and the first blue light chip 33) in the first light beads 30 and between the primary color chips (i.e., the second red light chip 41, the second green light chip 42, and the second blue light chip 43) in the second light beads 40, and can effectively avoid the occurrence of color deviation phenomenon, and further can effectively ensure the display effect of the LED display device. Therefore, the technical solution of this embodiment can effectively solve the problem that the LED display device in the related art has a color deviation phenomenon, which affects the display effect.

[0043] Specifically, the above-mentioned "setting direction of the first screen body 10" is the direction perpendicular to the docking side of the first screen body 10 and the second screen body 20 and parallel to the front surface of the first screen body 10, and the above-mentioned "setting direction of the second screen body 20" is the direction perpendicular to the docking side of the first screen body 10 and the second screen body 20 and parallel to the front surface of the second screen body 20.

[0044] In this embodiment, the inclination angle of the setting direction of each first light bead 30 on the first screen body 10 relative to the setting direction of the first screen body 10 is the same, and the inclination angle of the setting direction of each second light bead 40 on the second screen body 20 relative to the setting direction of the second screen body 20 is the same.

[0045] It should be noted that the LED display device of this embodiment can be an LED display device directly viewed by viewers or an LED display device used for XR virtual shooting.

[0046] Such as Figure 4 and Figure 5As shown, the first light-emitting diode (LED) bead 30 includes a first red light-emitting chip 31, a first green light-emitting chip 32, and a first blue light-emitting chip 33 arranged in a column. The setting direction of the first LED bead 30 is the extending direction of the first red light-emitting chip 31, the first green light-emitting chip 32, and the first blue light-emitting chip 33 on the first screen body 10; the second LED bead 40 includes a second red light-emitting chip 41, a second green light-emitting chip 42, and a second blue light-emitting chip 43 arranged in a column. The setting direction of the second LED bead 40 is the extending direction of the second red light-emitting chip 41, the second green light-emitting chip 42, and the second blue light-emitting chip 43 on the second screen body 20; wherein, in the direction away from the docking side edge 101 of the first screen body 10 and the second screen body 20, the arrangement trend of the first red light-emitting chip 31, the first green light-emitting chip 32, and the first blue light-emitting chip 33 of each first LED bead 30 is the same as the arrangement trend of the second red light-emitting chip 41, the second green light-emitting chip 42, and the second blue light-emitting chip 43 of each second LED bead 40. The arrangement trend includes the arrangement order and the arrangement orientation. In this way, when the viewer or the shooting device is located directly opposite the second screen body 20 (i.e., Figure 4 the viewing point 1 in), there is no relative occlusion between the primary color chips in the first LED bead 30 and between the primary color chips in the second LED bead 40, so that the light emitted by the primary color chips in the first LED bead 30 and the primary color chips in the second LED bead 40 can be completely projected onto the viewing point position, and the occurrence of color deviation can be avoided; when the viewer or the shooting device is located on the side of the first screen body 10 and the second screen body 20 (i.e., Figure 4 the position of the viewing point 2 or the viewing point 3 in), the first LED bead 30 and the second LED bead 40 have approximately the same deflection direction relative to the viewer or the shooting device, and the first LED bead 30 and the second LED bead 40 will have similar color deviations, which can effectively improve the problem of large color difference at the docking side of the first screen body 10 and the second screen body 20.

[0047] It should be noted that the above-mentioned "in the direction away from the docking side edge 101 of the first screen body 10 and the second screen body 20, the arrangement trend of the first red light-emitting chip 31, the first green light-emitting chip 32, and the first blue light-emitting chip 33 of each first LED bead 30 is the same as the arrangement trend of the second red light-emitting chip 41, the second green light-emitting chip 42, and the second blue light-emitting chip 43 of each second LED bead 40" means that the arrangement order and the arrangement orientation of the first red light-emitting chip 31, the first green light-emitting chip 32, and the first blue light-emitting chip 33 are the same as those of the second red light-emitting chip 41, the second green light-emitting chip 42, and the second blue light-emitting chip 43. Specifically, as Figure 5As shown in the figure, in the direction away from the docking side edge 101 of the first screen body 10 and the second screen body 20, the distances between the first red light chip 31, the first green light chip 32, and the first blue light chip 33 of each first light bead 30 and the docking side edge 101 gradually decrease. Correspondingly, the distances between the second red light chip 41, the second green light chip 42, and the second blue light chip 43 of each second light bead 40 and the docking side edge 101 gradually decrease; in the direction away from the docking side edge 101 of the first screen body 10 and the second screen body 20, the first red light chip 31, the first green light chip 32, and the first blue light chip 33 of each first light bead 30 extend towards the direction of the left side edge of the first screen body 10 in Figure 5 Figure 1, and correspondingly, the second red light chip 41, the second green light chip 42, and the second blue light chip 4 of each second light bead 40 extend towards Figure 5 the direction of the left side edge of the first screen body 10 in Figure 1.

[0048] Specifically, in this embodiment, the first included angle θ1 and the first viewing angle α of the viewing point position relative to the perpendicular bisector L1 of the first screen body 10 satisfy: θ1 = |arctan(T(α) + r1×cos(α))|, where T(α) is the mapping set of the mixed light uniformity of the first light bead 30 and the first viewing angle α, and r1 is an empirical value greater than 0 and less than 1; the second included angle θ2 and the second viewing angle β of the viewing point position relative to the perpendicular bisector L2 of the second screen body 20 satisfy: θ2 = |arctan(T(β) + r2×cos(β))|, where T(β) is the mapping set of the mixed light uniformity of the second light bead 40 and the second viewing angle β, and r2 is an empirical value greater than 0 and less than 1. By separately calculating the first included angle θ1 and the second included angle θ2 through the above two formulas, the influence of the color deviation phenomenon of the primary color chips in the first light bead 30 and the primary color chips in the second light bead 40 on the display effect can be reduced as much as possible.

[0049] When installing the LED display device, the spatial construction characteristics of the LED display device play an important role in determining the deflection angles (i.e., the first included angle θ1 and the second included angle θ2). The above-mentioned spatial construction characteristics specifically include: the number of screen bodies in the LED display device, the size of each screen body, the spatial position, the orientation, the spatial relationship between adjacent screen bodies, etc. The above-mentioned first viewing angle α and the second viewing angle β can be used to measure the spatial construction characteristics of the LED display device. By determining the first included angle θ1 and the second included angle θ2 through the first viewing angle α and the second viewing angle β, the display effect of the LED display device can be better.

[0050] As Figure 8 shown in the figure, for different viewing angle included angles, there are unique determined values for the mixed light uniformity of the light beads. Specifically, the mixed light uniformity parameters of the LED light beads can be obtained by measuring a single lamp in the laboratory or through the technical specification sheet.

[0051] Specifically, the above viewpoint position is any position within the viewpoint range determined according to the usage scenario of the LED display device (the viewpoint range is a set of positions where viewers or camera devices may appear in the physical space). Preferably, an optimal viewpoint position can be determined based on the experience of photographers, cameramen, or on-site layout personnel, and the first included angle θ1 and the second included angle θ2 are calculated through this optimal viewpoint position.

[0052] When arranging the LED display device of this embodiment, the arrangement orientation of the first light-emitting beads 30 on the first screen body 10 can be determined first, and then the first light-emitting beads 30 are welded to the first screen body 10 according to the calculated first included angle θ1; then, according to the arrangement orientation of the first light-emitting beads 30 and the calculated second included angle θ2, the second light-emitting beads 40 are welded to the second screen body 20. Of course, in other feasible implementation manners, the arrangement orientation of the second light-emitting beads 40 on the second screen body 20 can also be determined first, and then the arrangement orientation of the first light-emitting beads 30 on the first screen body 10 can be determined.

[0053] Figure 6 and Figure 11FIG. 0 shows a schematic structural diagram of the second embodiment of the LED display device according to the present application. Specifically, the difference between the second embodiment and the first embodiment of the present application is that the LED display device of the second embodiment includes three screen bodies (the first screen body 10, the second screen body 20, and the third screen body 50). Among them, the third screen body 50 is perpendicular to the first screen body 10 and the second screen body 20 in pairs and intersects at a point (specifically, in this embodiment, the first screen body 10 is a floor screen, and the second screen body 20 and the third screen body 50 are both vertical screens). A plurality of third lamp beads 60 are arranged in an array on the front surface of the third screen body 50. There is a third included angle θ3 between the setting direction of each third lamp bead 60 and the setting direction of the third screen body 50. Among them, the third lamp bead 60 includes a third red light chip 61, a third green light chip 62, and a third blue light chip 63 arranged in a column. The setting direction of the third lamp bead 60 is the extending direction of the third red light chip 61, the third green light chip 62, and the third blue light chip 63 on the third screen body 50. Among them, in the direction away from the docking side edge 101 of the first screen body 10 and the second screen body 20, the arrangement trend of the first red light chip 31, the first green light chip 32, and the first blue light chip 33 of each first lamp bead 30 is the same as the arrangement trend of the second red light chip 41, the second green light chip 42, and the second blue light chip 43 of each second lamp bead 40. In the direction away from the docking side edge 102 of the first screen body 10 and the third screen body 50, the arrangement trend of the first red light chip 31, the first green light chip 32, and the first blue light chip 33 of each first lamp bead 30 is the same as the arrangement trend of the third red light chip 61, the third green light chip 62, and the third blue light chip 63 of each third lamp bead 60. In the direction away from the docking side edge 103 of the second screen body 20 and the third screen body 50, the arrangement trend of the second red light chip 41, the second green light chip 42, and the second blue light chip 43 of each second lamp bead 40 is the same as the arrangement trend of the third red light chip 61, the third green light chip 62, and the third blue light chip 63 of each third lamp bead 60. The arrangement trend includes the arrangement order and the arrangement orientation.

[0054] Specifically, the above-mentioned "setting direction of the third screen body 50" is the direction perpendicular to the docking side edge 102 of the first screen body 10 and the third screen body 50 and parallel to the front surface of the third screen body 50.

[0055] In this embodiment, the meaning of "arrangement trend" in the arrangement trend of the first red light chip 31, the first green light chip 32, and the first blue light chip 33 of the first lamp bead 30, the arrangement trend of the second red light chip 41, the second green light chip 42, and the second blue light chip 43 of the second lamp bead 40, and the arrangement trend of the third red light chip 61, the third green light chip 62, and the third blue light chip 63 of the third lamp bead 60 is the same as the meaning in the first embodiment, and the meanings of "setting direction of the first screen body 10" and "setting direction of the second screen body 20" are the same as those in the first embodiment, which will not be elaborated here.

[0056] In this embodiment, the inclination angle of each first light-emitting diode (LED) 30 on the first screen body 10 relative to the setting direction of the first screen body 10 is the same, the inclination angle of each second LED 40 on the second screen body 20 relative to the setting direction of the second screen body 20 is the same, and the inclination angle of each third LED 60 on the third screen body 50 relative to the setting direction of the third screen body 50 is the same.

[0057] Specifically, as Figure 6 and Figure 7 shown, by setting the first LEDs 30 on the first screen body 10, the second LEDs 40 on the second screen body 20, and the third LEDs 60 on the third screen body 50 in the above manner, when the viewer or the shooting device is located at a position directly opposite the second screen body 20, or at a position directly opposite the third screen body 50, or at a position between the position directly opposite the second screen body 20 and the position directly opposite the third screen body 50, there is no relative occlusion between the primary color chips in the first LEDs 30, between the primary color chips in the second LEDs 40, and between the primary color chips (i.e., the third red light chip 61, the third green light chip 62, and the third blue light chip 63) in the third LEDs 60, so that the light emitted by the primary color chips in the first LEDs 30, the primary color chips in the second LEDs 40, and the primary color chips in the third LEDs 60 can be completely projected onto the viewing point position, and the occurrence of color deviation can be avoided; when the viewer or the shooting device is located at a position close to the docking side 101, the first LEDs 30 and the second LEDs 40 have an approximate deflection direction relative to the viewer or the shooting device, and the first LEDs 30 and the second LEDs 40 will have a similar color deviation, which can effectively improve the problem of large color difference at the docking side of the first screen body 10 and the second screen body 20; when the viewer or the shooting device is located at a position close to the docking side 102, the first LEDs 30 and the third LEDs 60 have an approximate deflection direction relative to the viewer or the shooting device, and the first LEDs 30 and the third LEDs 60 will have a similar color deviation, which can effectively improve the problem of large color difference at the docking side of the first screen body 10 and the third screen body 50.

[0058] Specifically, as Figures 8 to 11 shown, in this embodiment:

[0059] The first included angle θ1 and the first viewing angle α of the viewing point position relative to the perpendicular bisector L1 of the first screen body 10 satisfy: θ1 = |arctan(T(α) + r1×cos(α))|, where T(α) is the mapping set of the light mixing uniformity of the first LED 30 and the first viewing angle α, and r1 is an empirical value greater than 0 and less than 1;

[0060] The second included angle θ2 and the second viewing angle β of the viewpoint position relative to the perpendicular bisector L2 of the second screen body 20 satisfy: θ2 = |arctan(T(β) + r2×cos(β))|, where T(β) is the mapping set of the mixed light uniformity of the second light-emitting diode 40 and the second viewing angle β, and r2 is an empirical value greater than 0 and less than 1;

[0061] The third included angle θ3 and the third viewing angle γ of the viewpoint position relative to the perpendicular bisector L3 of the third screen body 50 satisfy: θ3 = |arctan(T(γ) + r3×cos(γ))|, where T(γ) is the mapping set of the mixed light uniformity of the third light-emitting diode 60 and the third viewing angle γ, and r3 is an empirical value greater than 0 and less than 1.

[0062] When installing the LED display device, the spatial construction characteristics of the LED display device play an important role in determining the deflection angles (i.e., the first included angle θ1, the second included angle θ2, and the third included angle θ3). The above-mentioned spatial construction characteristics specifically include: the number of screen bodies in the LED display device, the size of each screen body, the spatial position, the orientation, the spatial relationship between adjacent screen bodies, etc. The above-mentioned first viewing angle α, second viewing angle β, and third viewing angle γ can be used to measure the spatial construction characteristics of the LED display device. By respectively determining the first included angle θ1, the second included angle θ2, and the third included angle θ3 through the first viewing angle α, the second viewing angle β, and the third viewing angle γ, the display effect of the LED display device can be better.

[0063] Among them, r1, r2, and r3 are empirical values selected by designers based on experience, and can be specifically selected according to the installation environment of the LED display device, the light-emitting characteristics of the LED light-emitting diodes, etc.

[0064] By respectively obtaining the first included angle θ1, the second included angle θ2, and the third included angle θ3 through the above two formulas, the influence of the color deviation phenomenon of the primary color chips in the first light-emitting diode 30, the primary color chips in the second light-emitting diode 40, and the primary color chips in the third light-emitting diode 60 on the display effect can be reduced as much as possible.

[0065] For different viewing angle included angles, there is a uniquely determined value for the mixed light uniformity of the light-emitting diodes. Specifically, the mixed light uniformity parameters of the LED light-emitting diodes can be obtained by measuring a single light-emitting diode in the laboratory or through the technical specification sheet. The above-mentioned viewpoint position is any position within the viewpoint range determined according to the usage scenario of the LED display device. Preferably, an optimal viewpoint position can be determined according to the experience of photographers, cameramen, or on-site layout personnel, and the first included angle θ1, the second included angle θ2, and the third included angle θ3 can be calculated through this optimal viewpoint position.

[0066] When arranging the LED display device of this embodiment, the arrangement orientation of the lamp beads of one of the first screen body 10, the second screen body 20, and the third screen body 50 and the arrangement angle of the lamp beads relative to the screen body can be determined first according to the above formula; then, according to the arrangement orientation of the lamp beads of the first screen body and the above formula, the arrangement orientation and the arrangement angle of the lamp beads of the second screen body can be determined; then, the arrangement orientation and the arrangement angle of the lamp beads on the last screen body are determined.

[0067] As Figure 12 shown, the present application also provides a method for determining the arrangement mode of the lamp beads of an LED display device. This determination method is used to determine the arrangement modes of a plurality of first lamp beads 30 on the first screen body 10 and a plurality of second lamp beads 40 on the second screen body 20 arranged intersectingly in the first embodiment of the present application. Specifically, the determination method includes:

[0068] Step S10: Determine the viewpoint position of the viewer or the shooting machine relative to the first screen body 10 and the second screen body 20;

[0069] Step S20: Obtain a first angle θ1 between the setting direction of the first lamp beads 30 and the setting direction of the first screen body 10 and a second angle θ2 between the setting direction of the second lamp beads 40 and the setting direction of the second screen body 20 according to the viewpoint position.

[0070] Applying the technical solution of this embodiment, a plurality of first lamp beads 30 on the first screen body 10 are inclined relative to the first screen body 10 at the first angle θ1, and a plurality of second lamp beads 40 on the second screen body 20 are inclined relative to the second screen body 20 at the second angle θ2. In this way, it can effectively avoid light shielding between the primary color chips (i.e., the first red chip 31, the first green chip 32, and the first blue chip 33) in the first lamp beads 30 and between the primary color chips (i.e., the second red chip 41, the second green chip 42, and the second blue chip 43) in the second lamp beads 40, and can effectively avoid the occurrence of color cast phenomena, and further can effectively ensure the display effect of the LED display device. Specifically, by determining the first angle θ1 and the second angle θ2 according to the viewpoint position of the viewer or the shooting machine relative to the first screen body 10 and the second screen body 20, when the viewer views the LED display device or shoots the LED display device, the viewing effect or the shooting effect will not be affected by color cast. Therefore, the technical solution of this embodiment can effectively solve the problem that the LED display device in the related art has a color cast phenomenon that affects the display effect.

[0071] The determination method of this embodiment further includes:

[0072] Step S31: Determine the arrangement trend of the first red light chip 31, the first green light chip 32, and the first blue light chip 33 of the first light bead 30 in the direction away from the docking side 101 of the first screen body 10 and the second screen body 20.

[0073] Step S32: Determine the arrangement trend of the second red light chip 41, the second green light chip 42, and the second blue light chip 43 of the second light bead 40 according to the arrangement trend of the first red light chip 31, the first green light chip 32, and the first blue light chip 33. Among them, in the direction away from the docking side 101 of the first screen body 10 and the second screen body 20, the arrangement trend of the first red light chip 31, the first green light chip 32, and the first blue light chip 33 of each first light bead 30 is the same as the arrangement trend of the second red light chip 41, the second green light chip 42, and the second blue light chip 43 of each second light bead 40. The arrangement trend includes the arrangement order and the arrangement orientation.

[0074] In this way, when the viewer or the shooting device is located directly opposite the second screen body 20 (i.e., Figure 4 the viewing point 1 in Figure 4 ), there is no relative occlusion between the primary color chips in the first light bead 30 and the primary color chips in the second light bead 40, so that the light emitted by the primary color chips in the first light bead 30 and the primary color chips in the second light bead 40 can be completely projected onto the viewing point position, and the occurrence of color deviation can be avoided; when the viewer or the shooting device is located on the side of the first screen body 10 and the second screen body 20 (i.e., Figure 4 the position of the viewing point 2 or the viewing point 3 in ), the first light bead 30 and the second light bead 40 have an approximate deflection direction relative to the viewer or the shooting device, and the first light bead 30 and the second light bead 40 will have similar color deviations, which can effectively improve the problem of large color differences at the docking side of the first screen body 10 and the second screen body 20.

[0075] Specifically, the steps of obtaining the first included angle θ1 between the setting direction of the first light bead 30 and the setting direction of the first screen body 10 and the second included angle θ2 between the setting direction of the second light bead 40 and the setting direction of the second screen body 20 according to the viewing point position include:

[0076] Step S21: Obtain the first viewing point included angle α of the viewing point position relative to the perpendicular bisector L1 of the first screen body 10 according to the viewing point position, and calculate the first included angle θ1 according to the first viewing point included angle α. Among them, the following relationship is satisfied between the first included angle θ1 and the first viewing point included angle α:

[0077] θ1 = |arctan(T(α) + r1×cos(α))|,

[0078] T(α) is the mapping set of the mixing uniformity of the first light bead 30 and the first viewing point included angle α, and r1 is an empirical value greater than 0 and less than 1;

[0079] Step S22: Obtain the second viewing angle β of the viewing point position with respect to the perpendicular bisector L2 of the second screen body 20 according to the viewing point position, and calculate the second angle θ2 based on the second viewing angle β. Among them, the following relationship is satisfied between the second angle θ2 and the second viewing angle β:

[0080] θ2 = |arctan(T(β) + r2×cos(β))|,

[0081] T(β) is the mapping set of the mixed light uniformity of the second light bead 40 and the second viewing angle β, and r2 is an empirical value greater than 0 and less than 1.

[0082] As Figure 13 shown, the present application also provides a method for determining the arrangement manner of the light beads of an LED display device. This determination method is used to determine the arrangement manner of the multiple first light beads 30 on the first screen body 10, the arrangement manner of the multiple second light beads 40 on the second screen body 20, and the arrangement manner of the multiple third light beads 60 on the third screen body 50 in the second embodiment of the present application.

Among them, in the direction away from the docking side edge 101 of the first screen body 10 and the second screen body 20, the arrangement trend of the first red light chip 31, the first green light chip 32, and the first blue light chip 33 of each first light bead 30 is the same as the arrangement trend of the second red light chip 41, the second green light chip 42, and the second blue light chip 43 of each second light bead 40.

[0093] Step S202: Obtain the second viewpoint included angle β of the viewpoint position relative to the perpendicular bisector L2 of the second screen body 20 and calculate the second included angle θ2 according to the second viewpoint included angle β. Among them, the following relationship is satisfied between the second included angle θ2 and the second viewpoint included angle β:
