Detailed ways

In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that a thorough understanding of the present disclosure will be provided.

Referring to Figures 1 and 2, the present invention discloses a display system 10 for extended reality, which can be used as a virtual shooting studio to achieve the shooting of special effects pictures and obtain picture effects close to the real scene, so as to reduce the change of the real scene scene and save money. cost.

The display system 10 for extended reality at least includes a wall screen 11 and a transition screen 13. The wall screen 11 includes a plurality of first display screens 111 in a straight screen structure. The plurality of first display screens 111 are spliced into a cylindrical shape on the display side. The wall screen 11 can be installed on a supporting surface such as a horizontal ground, so that the axis of the wall screen 11 is perpendicular to the horizontal plane. When the wall screen 11 is installed on the horizontal ground, the intersection of the vertical plane coplanar with the axis of the wall screen 11 and the display side of the wall screen 11 is linear, and the intersection of the display side of the wall screen 11 and the horizontal plane is circular. Arc shape.

Of course, the supporting surface for installing the wall screen 11 is not limited to the horizontal ground. For example, the supporting surface may be a plane inclined to the horizontal plane, and the supporting surface is not limited to a flat surface.

The transition screen 13 is connected to one end of the wall screen 11 and extends in a direction away from the wall screen 11 . The transition screen 13 includes a plurality of second display screens 131 with a straight screen structure. The plurality of second display screens 131 are spliced into the transition screen 13 . The display side of the screen 13 is in the form of a curved surface with the axis of the wall screen 11 as the rotation axis, and the busbar on the display side of the transition screen 13 is in the shape of an arc. In other words, when the wall screen 11 is installed on the horizontal ground, the intersection between the vertical plane coplanar with the axis of the wall screen 11 and the display side of the transition screen 13 is arc-shaped, and the horizontal plane perpendicular to the axis of the wall screen 11 is in the shape of an arc. The intersection line on the display side of the screen 13 is also arc-shaped. In the embodiment of the present invention, the display sides of the transition screen 13 and the wall screen 11 both face the inside of the display system 10 , that is, toward the axis extension direction of the wall screen 11 .

In some embodiments, both ends of the bus bar on the display side of the transition screen 13 are spaced from the rotation axis, so the transition screen 13 formed by rotation forms a first opening 13 a at an end away from the wall screen 11 . The first opening 13a can be used to install a canopy, that is, the first opening 13a can be covered with a flat display screen to obtain a larger display range. For example, referring to Figure 3, in the embodiment shown in Figure 3, the diameter of the first opening 13a is approximately 12m.

In other embodiments, the end of the bus bar of the transition screen 13 away from the wall screen 11 can be located on the rotation axis, so that the transition screen 13 formed by rotation is closed at the end away from the wall screen 11, and in this embodiment, The display side of the transition screen 13 formed by rotation may be part of a spherical surface.

In the embodiment of the present invention, the cylindrical display side of the wall screen 11 can also be regarded as a curved surface of revolution, that is, the display side of the wall screen 11 is formed by rotating a segment-shaped busbar around a fixed axis. Therefore, the combination of the transition screen 13 and the wall screen 11 can be regarded as a rotational curve on the display side. Its busbar is a shape in which one end of the line segment is connected with an arc, and its rotation axis is the same fixed axis. In particular, the bus bar of the transition screen 13 can be tangent to the bus bar of the wall screen 11, so that on the display side, the transition screen 13 and the wall screen 11 transition smoothly, preventing dark lines from being generated at the connection between the transition screen 13 and the wall screen 11 when displaying the picture. or bright lines.

It can be understood that the rotation angle of the transition screen 13 and the rotation angle of the wall screen 11 can be equal, for example, both are 270 degrees. In this embodiment, the wall screen 11 forms a second opening 11a, and the second opening 11a extends to the first opening 13a. Specifically, to simplify the description, it can be considered that the transition screen 13 in the shape of a revolution surface has a meridional direction and a latitudinal direction (refer to FIG. 2). The second opening 11a of the wall screen 11 is provided on the side of the wall screen 11 and is parallel to the wall screen. 11 extends in the direction of the axis and extends in the meridional direction to the first opening 13a.

In particular, in some embodiments, the rotation angle of the transition screen 13 is equal to the rotation angle of the wall screen 11 and is 360 degrees. Therefore, in the horizontal direction, the transition screen 13 and the wall screen 11 are circumferentially closed, that is, in a When displayed within the system 10, a 360-degree viewing angle can be obtained in the horizontal direction. In this embodiment, a door for entry and exit can be provided on the wall screen 11 , and the door is also formed by splicing the first display screen 111 .

In other embodiments, the rotation angle of the transition screen 13 may be smaller than the rotation angle of the wall screen 11 . For example, the rotation angle of the wall screen 11 is 270 degrees, and the rotation angle of the transition screen 13 is 250 degrees.

In some embodiments, the display system 10 for extended reality may include a ground screen 15 connected to an end of the wall screen 11 away from the transition screen 13 , and the wall screen 11 is disposed at and along the edge of the ground screen 15 extend. For example, in the embodiment of the present invention, the ground screen 15 is roughly circular with a diameter of about 24 m, and the wall screen 11 is disposed on the edge of the ground screen 15 and extends along the edge of the ground screen 15 . In an embodiment in which the wall screen 11 is provided with the second opening 11 a, the second opening 11 a may also extend to the ground screen 15 .

Furthermore, the ground screen 15 may include a plurality of third display screens 151 with a straight screen structure, and the plurality of third display screens 151 are spliced into a ground screen 15 with a flat display side. In some embodiments, the third display screen 151 is in the shape of a rectangular block. The arrangement of LED lamp beads for displaying colors in the third display screen 151 of a rectangular block is relatively easy. For example, the third display screen 151 of a rectangular block shape The LED lamp beads in the screen 151 can be arranged in rows and columns, with the row direction parallel to the wide side of the rectangle and the column direction parallel to the long side of the rectangle.

Similarly, the first display screen 111 can also be in the shape of a rectangular block. The arrangement of the LED lamp beads for displaying colors in the first display screen 111 in the shape of a rectangular block is relatively easy. For example, the first display screen 111 in the shape of a rectangular block can be The LED lamp beads in 111 can be arranged in rows and columns, with the row direction parallel to the wide side of the rectangle and the column direction parallel to the long side of the rectangle.

In related technologies, the curved screen structure generally requires special design of the display screen structure to obtain the desired continuous curved display side. This specific curved screen generally requires customized design and is relatively difficult to manufacture, resulting in The cost is on the high side. Moreover, when meeting different size requirements, such as curved screens with different radii, the design generally needs to be changed, resulting in a relatively low versatility of this curved screen structure. In the embodiment of the present invention, the display side of the display screen of the straight screen structure is flat or in the shape of multiple plane splicing, which is different from the display side of the curved screen structure, which is a continuous curved structure. The splicing method is not limited to setting up trusses or splicing. Each first display screen 111, second display screen 131 or third display screen 151 is equipped with a splicing structure. This arrangement can simplify the structure of the display screen and combine the first display screen 111, the second display screen 131 and the third display screen 151. The display screen 151 is made into a relatively universal module and can be assembled according to the size requirements, thereby reducing the manufacturing and construction costs of the display system 10 .

It can be understood that in the embodiment of the present invention, since the first display screen 111 and the second display screen 131 with a straight screen structure are used as spliced units, the display sides of the spliced wall screen 11 and transition screen 13 should not be It is understood as a geometrically strict cylindrical surface or arc line. Instead, the cylindrical surface or the surface of revolution is discretized using a rectangular grid or a trapezoidal grid, and the arc with continuous curvature is discretized into a line segment connected end to end, which satisfies engineering requirements. The error requirements are sufficient. Therefore, the expressions of cylindrical surfaces, revolution surfaces, and arc lines in the embodiments of the present invention are for easy understanding of the structure and shape of the display system 10 and should not be understood as necessarily strictly conforming to geometric definitions.

Referring to FIG. 4 , in some embodiments, the radius R of the busbar on the display side of the transition screen 13 is equal to the height H of the wall screen 11 in its axial direction. For example, in the embodiment of the present invention, the height of the wall screen 11 in its axial direction is 6 meters, and the bus radius of the transition screen 13 is also 6 meters. During the working process of the display system 10, the camera is generally installed in the central area of the second opening 11a. The above-mentioned installation method can make the camera capture the best picture effect. In particular, for the display system for a virtual studio of the present invention, since the camera is generally installed in a fixed position and can rotate relative to the ground, the change in shooting angle of the camera during rotation can be consistent with the rotational curved surface wall screen 11 and the transition. The screen 13 achieves better matching, making the pictures captured by the camera more natural and preventing the distortion of the pictures captured. The advantages of this kind of curved screen can be compared to the visual impact of the curved screen (i.e. display system) used in large-scale games on the game operator (i.e. camera). Compared with related technologies, using a design that includes a direct-facing wall screen, when the camera's shooting angle is facing the direct-facing wall screen, a relatively good shooting picture can be obtained, but when the shooting angle is large, it is easy to display a severely deformed shooting picture. Especially for situations where a direct wall screen is connected to a curved surface, the camera position is even more difficult to arrange. However, the curved surface wall screen 11 and the transition screen 13 of the present invention can better solve the above problems, making it easier to arrange the camera positions and making the shooting pictures more natural.

Of course, in other embodiments, the height H of the wall screen 11 in its axial direction may be larger or smaller than the radius R of the bus bar on the display side of the transition screen 13 .

Referring to FIG. 5 , in some embodiments, the second display screen 131 is in the shape of a trapezoidal block. From the connection position between the transition screen 13 and the wall screen 11 to the extending direction away from the wall screen 11 , the display side of the second display screen 131 The area gradually decreases, that is, in the height direction of the axis of the wall screen 11, the transition screen 13 gradually shrinks inward and approaches the axis of the wall screen 11. Specifically, referring to FIG. 5 , in the axial direction of the wall screen 11 , the upper and lower lengths of the second display screen 131 of the same height are equal and the lengths of the lower and lower bases are also equal. For two adjacent layers of second display screens 131, the length of the bottom of the second display screen 131 of the higher level is equal to the length of the top and bottom of the second display screen 131 of the lower level. The length of the top and bottom of 131 is smaller than the length of the top and bottom of the second display screen 131 one level below.

Referring to Figure 6, in some embodiments, the second display screen 131 includes lamp beads 1311 arranged in an array. The number of lamp beads 1311 in any two rows is equal, starting from the connection position of the transition screen 13 and the wall screen 11 and moving away from the wall. In the extending direction of the screen 11 , the arrangement density of the lamp beads 1311 in the row direction close to the wall screen 11 is smaller than the arrangement density of the lamp beads 1311 in the row direction away from the wall screen 11 . The row arrangement direction of the lamp beads 1311 is consistent with the meridian direction of the transition screen 13 , and the column arrangement direction of the lamp beads 1311 is consistent with the latitude direction of the transition screen 13 . In the meridian direction of the transition screen 13 , the The in-row arrangement density of lamp beads 1311 close to the wall screen 11 is smaller than the in-row arrangement density of lamp beads 1311 far away from the wall screen, that is, in the direction extending from the wall screen 11 to the first opening 13a, for the same second display screen 131. The closer to the first opening 13a, the greater the in-row arrangement density of the lamp beads 1311. In other words, for the same second display screen 131, the higher the latitude, the greater the in-row arrangement density of the lamp beads 1311.

In the embodiment of the present application, the wall screen 11 , the transition screen 13 and the ground screen 15 are all LED lights used for light-emitting display. For example, as shown in FIG. 6 , the lamp beads 1311 of the second display screen 131 are arranged in 9 rows and 5 columns, the number of lamp beads 1311 in each row is 5, and the spacing between any two adjacent rows is equal. From the connection position between the transition screen 13 and the wall screen 11 to the extending direction away from the wall screen 11 , as the width of the second display screen 131 gradually decreases, the arrangement density of the lamp beads 1311 in each row gradually increases. In this implementation, since the number of lamp beads 1311 in each row remains unchanged, a better display effect can be obtained compared to an arrangement in which the density of lamp beads 1311 gradually decreases as the width decreases.

Further, referring to Figure 7, in the axis direction of the wall screen 11, that is, the height direction of the display system 10, a second display screen 131 at the same height, that is, a second display screen 131 on the same layer or a second display screen at the same latitude. 131. For two second display screens 131 that are spliced together, the distance d between the two lamp beads 1311 located in different second display screens 131 close to the splicing point is different from the distance d between the same lamp beads 1311 in the same second display screen 131. The distance d1 (or d2) is similar. The above arrangement can be simply understood as: for the second display screen 131 on the same layer, for the two second display screens 131 that are spliced together, the rows of lamp beads 1311 in one of the second display screens 131 are the same as those in the other. The rows of lamp beads 1311 in the second display screen 131 correspond to each other and are aligned one by one. The distance d between the two lamp beads 1311 located near the splicing point and located in different second display screens 131 is the same as that of the same second display screen 131 The difference in the spacing d1 (or d2) between the lamp beads 1311 in the same row is within 5%.

Illustratively, referring to FIG. 7 , taking two adjacent second display screens 131 as an example, at one height of the axis of the wall screen 11 , that is, at the same latitude, the two second display screens 131 are spliced to each other. The distance d1 (or d2) between the lamp beads 1311 is 2.6 mm, and the distance d between two lamp beads 1311 located in the same row of different second display screens 131 close to the splicing point is also 2.6 mm. In the embodiment of the present invention, the distance between two lamp beads 1311 can be understood as the distance between the centers of the two lamp beads 1311 .

Combined with Figure 8, since the luminous intensity of the LED lamp has strong directivity, the light intensity is maximum in the normal direction of the LED lamp. When it deviates from the normal direction at different angles, the light intensity also changes accordingly. In short, the light intensity of LED lights has the highest intensity in its normal direction, and its side light intensity attenuates quickly. Figure 8(a) exemplarily shows two adjacent lamp beads 1311 in the second display screen 131. The rectangle in the figure represents the lamp bead, and the circle outside the rectangle represents the light radiation intensity. In Figure 8(a) Under normal arrangement, without considering interference and other conditions, it can be simply considered that the position where the light intensity attenuates 50% is located at the center of the connection between the two lamp beads 1311. Under this normal arrangement, the two lamp beads 1311 There is no dark line or bright line at the center of the connection; under other conditions being the same, when the distance between the two lamp beads 1311 is smaller than the distance between the two lamp beads 1311 in Figure 8(a), as shown in Figure 8(b) In the case of , the light intensity generated in the central area of the connection between the two lamp beads 1311 is superimposed, that is, a bright line appears; when the distance between the two lamp beads 1311 is greater than the distance between the two lamp beads 1311 in Figure 8(a), As shown in Figure 8(c), the light intensity in the central area of the connection between the two lamp beads 1311 is insufficient, that is, a dark line appears.

Therefore, by adopting the setting method of the present invention, dark lines or bright lines can be prevented from being generated at the splicing point of the two second display screens 131 when displaying images, thereby improving the display effect of the display system 10 .

It can be understood that in the extension direction of the axis of the wall screen 11, that is, the height direction of the display system 10, the second display screens 131 of different layers that are spliced to each other can also be arranged in this way, that is, the second display screens 131 located close to the splicing point are The distance between the two lamp beads 1311 of different second display screens 131 is similar to the row spacing of the lamp beads 1311 in the same second display screen 131 to prevent dark lines from being generated at the splicing of the two second display screens 131 when displaying images. or bright lines, thereby improving the display effect of the display system 10 .

Similarly, in the extension direction of the axis of the wall screen 11, that is, the height direction of the display system 10, the first display screens 111 of different layers that are spliced to each other can also be designed in this way, that is, the first display screens 111 located at different levels close to the splicing point. The spacing between the two lamp beads of a display screen 111 is similar to the row spacing of the lamp beads in the same first display screen 111, so as to prevent dark lines or bright lines from being produced at the splicing of the two first display screens 111 when displaying a picture. Thus, the display effect of the display system 10 is improved. Of course, the first display screens 111 located on the same layer, that is, at the same height, can also be arranged in this manner, that is, the distance between the two lamp beads located on different first display screens 111 close to the splicing point is different from that of the same first display screen. The spacing between the same lamp beads in 111 is similar to prevent dark lines or bright lines from being generated at the splicing of the two first display screens 111 when displaying the picture, thereby improving the display effect of the display system 10 .

In the embodiment shown in FIGS. 4 and 5 , the height of the second display screen 131 of the transition screen 13 is similar to the height of the first display screen 111 of the wall screen 11 , that is, in the axis extension direction of the wall screen 11 , that is, In the height direction of the display system 10, when the second display screen 131 is placed vertically, its height is similar to the height of the first display screen 111, for example, the height difference is within 5%. In this embodiment, the area of the display side of the transition screen 13 is relatively large, and the manufacturing is relatively simple.

Referring to Figures 9 and 10, in other embodiments, in the meridian direction of the transition screen 13, the second display screen 131 includes a plurality of display units 1313 in a straight screen structure, and the multiple display units 1313 are sequentially spliced along the meridian direction. . For example, in the embodiments shown in FIGS. 10, 11, and 12, any second display screen 131 includes four display units 1313 spliced along the height direction or the meridional direction, and the four display units 1313 are spliced into a second display. The height of the screen 131 is similar to the height of the first display screen 111 . In other words, the length of the display unit 1313 in the meridional direction is smaller than the length of the first display screen 111 in the axial direction of the wall screen 11 . For example, in one embodiment, the height of each display unit 1313 is 250 mm, and the included angle between adjacent display units 1313 in the same second display unit 1313 is approximately 177.5 degrees.

The display side of the display unit 1313 is flat, that is, the display unit 1313 has a straight screen structure. In other embodiments, the second display screen 131 may be formed by splicing more display units 1313 . Of course, the second display screen 131 can also be formed by splicing two or three display units 1313 . This splicing structure of the second display screen 131 can form a shape closer to a smooth curved surface on the display side of the second display screen 131 to obtain a better display effect.

Furthermore, in some embodiments, the row spacing of the lamp beads 1311 in the display unit 1313 is equal, and the display sides of adjacent display units 1313 form a smaller acute angle. For ease of understanding, in the embodiment of the present invention, the row direction of the lamp beads 1311 in the first display screen 111 or the second display screen 131 is parallel to the horizontal direction or the weft direction, and the column direction of the first display screen 111 is parallel to the vertical direction. The directions are parallel, and the column direction of the display units 1313 of the second display screen 131 is at an angle with the vertical direction. In the embodiment shown in Figures 12 and 13, adjacent display units 1313 in the same second display screen 131 are displaying The angle between the two sides is 2.5 degrees, and the row spacing of the lamp beads 1311 of the display unit 1313 is about 2.5 mm. This structural arrangement can not only make the display side of the second display screen 131 form a shape closer to a smooth curved surface, but also prevent dark lines or bright lines from being generated at the splicing of the two display units 1313 when displaying a picture, thereby improving the transition screen 13 and the display effect of the display system 10.

Referring to Figure 14 (a) and Figure 14 (b), in some embodiments, an arc track (not shown) can be provided on the edge of the ground screen 15, and the transition screen 13 includes at least two sub-transition screens (not shown), The wall screen 11 includes at least two sub-wall screens 16. The sub-transition screens in the same meridian direction are connected to the sub-wall screens 16 correspondingly. The side of at least one sub-wall screen 16 close to the ground screen 15 is slidably matched with the arc track, and the corresponding connected sub-wall screens 16 are connected to each other in a sliding manner. The transition screen and the sub-wall screen 16 can slide along the arc track to be stacked outside the adjacent sub-wall screens 16 and sub-transition screens, thereby reducing the display range of the wall screen 11 and the transition screen 13. Of course, the sub-wall screen 16 and sub-transition screen in the stacked state can also be slid to the original position to expand the display range of the wall screen 11 and the transition screen 13 .

For example, the first display screen 111 at the same longitude, or the first display screen 111 within a preset longitude range, can be combined into the sub-wall screen 16, the second display screen 131 at the same longitude, or the second display screen 131 within the preset longitude range. The display screen 131 can be combined into a sub-transition screen. The sub-transition screens and sub-wall screens 16 in the same meridian direction are connected correspondingly and the number of sub-transition screens and sub-wall screens 16 can be equal. The correspondingly connected sub-transition screens and sub-wall screens 16 can be along an arc track. Slide to overlap outside the adjacent sub-wall screen 16 and sub-transition screen, thereby reducing the display range of the wall screen 11 and transition screen 13 .

For example, in the embodiment shown in FIG. 14(a) and FIG. 14(b) , the wall screen 11 can be equally divided into five sub-wall screens 16. Correspondingly, the transition screen 13 can also be divided into five sub-transition screens, and the five sub-wall screens 16 are connected to the five sub-transition screens in one-to-one correspondence. When all the sub-wall screens 16 are opened for display, the wall screen 11 and the transition screen 13 have a display range of 300 degrees in the horizontal direction; one of the outermost sub-wall screens 16 is stacked on the adjacent sub-wall. Behind the outside of the screen 16, the display range of the wall screen 11 and the transition screen 13 in the horizontal direction is adjusted to 240 degrees, so that the display range of the wall screen 11 and the transition screen 13 can be adjusted according to use needs to improve the flexibility of the display system 10. This expands usage scenarios and improves the versatility of the display system 10 . It can be understood that the number of correspondingly connected sub-wall screens 16 and sub-transition screens may not be equal. For example, the number of sub-wall screens 16 may be one, and the number of sub-transition screens may be two or three.

Furthermore, for the display system 10 provided with a canopy, another arc-shaped track can also be provided at the connection position between the canopy and the transition screen 13, so that the end of the transition screen 13 away from the wall screen 11 is slidably matched with the other arc-shaped track. . When the end of the sub-wall screen 16 close to the ground screen 15 slides along the arc-shaped track, the sub-transition screen can slide along the other arc-shaped track, thereby improving the smoothness of the sliding of the sub-wall screen 16 and the sub-transition screen and preventing the sub-transition screen from sliding along the arc-shaped track. An inclination is generated during the sliding process to improve the movement reliability of the sub-wall screen 16 and the sub-transition screen and to increase the service life of the arc track.

In particular, in this embodiment, a position sensor such as a photoelectric sensor or a Hall sensor can also be provided on the ground screen 15 or other locations. The position sensor is used to detect the display range of the wall screen 11 on the display side of the display system 10. Processing The display device is configured to adjust the display screen according to the display range detected by the position sensor, so as to match the screen with the display system 10 . For example, when the sub-wall screens 16 and sub-transition screens within a certain longitude range are superimposed on the adjacent sub-wall screens 16 and sub-transition screens, the position sensor in the original area no longer detects the obstruction of the sub-wall screens 16, and can then The detection result determines the display range of the display side of the wall screen 11. In response to the display range, the processor adaptively adjusts the display screen to match the screen with the display system 10 and obtain the required display effect. For example, the display range of the display system 10 when the sub-wall screen 16 and the sub-transition screen are fully expanded is 300 degrees. In some cases, the display range required for virtual shooting is 240 degrees. At this time, the display range can be One of the sub-wall screens 16 and the sub-transition screen is stacked outside the adjacent sub-wall screen 16 and the sub-transition screen. The display range determined by the detection result of the position sensor is 240 degrees. The processor can respond to the display range detected by the position sensor. The original display screen is cropped to obtain the screen to be displayed, and then the display system 10 is controlled to display the screen to be displayed to meet the requirement of a 240-degree display range, that is, to achieve matching between the screen and the display system 10 . For example, in this implementation, the size of the image to be displayed and the original display image in the meridional direction remain unchanged, but the display range in the latitudinal direction is reduced. The original display screen can be understood as matching the display range when the display system is fully expanded.
