In fact, there is a certain error between the two, that is, the actual light point does not coincide with the theoretical light point, which will cause the display image to be inconsistent with the actual and the actual voxel points to be unevenly distributed, such as Figure 1 shown.

[0033] The following will be combined with the specific embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments and / or examples of the present invention. Obviously, the embodiments and / or examples described below are only part of the embodiments and / or examples of the present invention, rather than all the embodiments and / or examples. Based on the embodiments and / or examples in the present invention, all other embodiments and / or examples obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The directional terms mentioned in the present invention, such as [upper], [lower], [left], [right], [front], [back], [inner], [outer], [side], etc., are only referenced to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention. The terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0035] Take the rotating display device as an example, the display component is a single light bar, there is a row of light units on the single light bar, when the light bar rotates with the center or end point as the axis, the visual persistence effect can be used to achieve a flat display, the moving path of the light unit is a concentric circle, when the light unit is illuminated at a fixed refresh frequency, the actual pixel distribution of the rotating display device is as follows: Figure 2 As shown, it is a multi-layer, equally spaced circular matrix with dense inner and sparse outer layers. The specific number of circular layers is related to the number of light-emitting units and the position of the rotation axis. However, within a rotation cycle, when the display times of each light-emitting unit are the same, the closer to the axis, the smaller the rotation radius of the light-emitting unit, the shorter the circumference of the rotation path, and the light-emitting units are too densely displayed, which will cause the pixel points actually displayed by the rotating display device to be unevenly distributed, resulting in serious crosstalk and overlap between pixels, and unnecessary power consumption loss.

[0036] In view of the above problem of uneven pixel distribution in a rotating display device, the present invention provides a display method for a rotating display device, which can adjust the number of pixels in each layer to even out the pixel distribution of the rotating display device.

[0037] Embodiment 1

[0038] Please refer to Figure 3(a) to Figure 3(c)The display component of the rotating display device is a single light bar 10, and there is a row of light-emitting units 11 on the single light bar 10, and the number of the light-emitting units is 2n or 2n+1. The rotating display device has a rotation center point O, and the light-emitting units 11 are symmetrically distributed on both sides of the rotation center point O, and the light-emitting units 11 rotate around the rotation center point O with the rotation center point O as the center of the circle.

[0039] In the first embodiment, as shown in Figure 3(a), the number of the light-emitting units is 2n, n light-emitting units 11 are arranged on the left side of the rotation center point O, n light-emitting units 11 are arranged on the right side of the rotation center point O, and the distances between the light-emitting units 11 and the rotation center point O are a, 2a, 3a...na respectively.

[0040] The display method of the rotating display device provided by the embodiment of the present invention includes:

[0041] In one rotation cycle, the display times of the light emitting unit 11 whose distance from the rotation center point O is na is m, and the display times of the light emitting unit 11 whose distance from the rotation center point O is ka is mk / n; wherein k is an integer greater than or equal to 1 and less than n.

[0042] Specifically, the distance between the outermost light-emitting unit 11 of the single light bar 10 and the rotation center point O is na, the rotation radius of the outermost light-emitting unit 11 is na, and within one rotation cycle, the rotation path of the outermost light-emitting unit 11 is 2πna. The number of times the outermost light-emitting unit 11 is displayed is m, and the time interval between each two adjacent displays is equal. In order to achieve a higher resolution of the rotating display device, the value of m is usually large, and the spacing value a between two adjacent light-emitting units 11 is relatively small; according to the principle of calculus, the rotation path of the outermost light-emitting unit 11 is divided into m equal segments, and the size of each segment dl=2πna / m, then the area of ​​the light-emitting unit 11 each time is recorded as the area of ​​the ring where the segment dl is located, which can be approximately recorded as a*dl / 2, such as Figure 6 As shown; integrating the a*dl / 2, we get Figure 7 The area of ​​the ring shown is the light-emitting area of ​​the light-emitting unit 11 in one rotation cycle.

[0043] Therefore, in one rotation cycle, the light emitting area of ​​the outermost light emitting unit 11 is πna 2 , the corresponding display times is m, and the area displayed each time is πna 2 / m; According to the above principle, the light emitting area of ​​the light emitting unit 11 at a distance ka from the rotation center point O is πka 2 , the corresponding display times is mk / n, and the area displayed each time is πna 2 / m. It should be noted that, in the embodiment of the present invention, the time interval between any two adjacent displays of the same light-emitting unit 11 is the same; the ratio of the display time intervals of the light-emitting unit whose distance from the rotation center O is ka and the light-emitting unit whose distance from the rotation center O is na is n / k. By adopting the display method provided in the embodiment of the present invention to drive the rotating display device for rotational display, the areas of single light-emitting display of any two light-emitting units 11 on the display component are the same, so that the actual pixel points of the rotating display device are evenly distributed, avoiding the problem of crosstalk and ghosting between pixels due to the over-dense display of the light-emitting units 11 close to the rotation center O, and reducing power consumption loss.

[0044] In a second embodiment, as shown in FIG3(b), the number of the light-emitting units is 2n, n light-emitting units 11 are arranged on the left side of the rotation center point O, n light-emitting units 11 are arranged on the right side of the rotation center point O, and the distances between the light-emitting units 11 and the rotation center point O are 1 / 2a, (1+1 / 2)a, (2+1 / 2)a......(n-1 / 2)a respectively.

[0045] The display method of the rotating display device provided by the embodiment of the present invention includes:

[0046] In one rotation cycle, the number of times the light-emitting unit 11 whose distance from the rotation center point O is (n-1 / 2)a is displayed is m, and the number of times the light-emitting unit 11 whose distance from the rotation center point O is (k-1 / 2)a is displayed is (2k-1)m / (2n-1); wherein k is an integer greater than or equal to 1 and less than n.

[0047] Specifically, according to the display principle in the first embodiment, within one rotation cycle, the light emitting area of ​​the outermost light emitting unit 11 is (n-1 / 2)πa 2 , the corresponding display times is m, and the area displayed each time is (n-1 / 2)πa 2 / m; According to the above principle, the light emitting area of ​​the light emitting unit 11 at a distance ka from the rotation center point O is (k-1 / 2)πa 2 , the corresponding display times is (2k-1)m / (2n-1), and the area displayed each time is (n-1 / 2)πa 2 / m. Similarly, by adopting the display method provided by the embodiment of the present invention to drive the rotating display device to perform rotating display, the areas of single light-emitting display of any two light-emitting units 11 on the display component are the same, so that the actual pixel points of the rotating display device are evenly distributed, avoiding the problem of crosstalk and ghosting between pixels due to the over-dense display of the light-emitting units 11 close to the rotation center point O, and reducing power consumption loss.

[0048] In the third embodiment, as shown in FIG3(c), the number of the light-emitting units 11 is 2n+1, one light-emitting unit 11 is arranged on the rotation center point O, n light-emitting units 11 are arranged on the left side of the rotation center point O, n light-emitting units 11 are arranged on the right side of the rotation center point O, and the distances between the light-emitting units 11 on the left and right sides and the rotation center point O are a, 2a, 3a...na respectively.

[0049] The display method of the rotating display device provided by the embodiment of the present invention includes:

[0050] In one rotation cycle, the display times of the light-emitting unit 11 whose distance from the rotation center point O is na is m, the display times of the light-emitting unit 11 whose distance from the rotation center point O is ka is mk / n, and the display times of the light-emitting unit 11 located at the rotation center point O is 1; wherein k is an integer greater than or equal to 1 and less than n.

[0051] Specifically, according to the display principle in the first embodiment, within one rotation cycle, the light emitting area of ​​the outermost light emitting unit 11 is πna 2 , the corresponding display times is m, and the area displayed each time is πna 2 / m; According to the above principle, the light-emitting area of ​​the light-emitting unit 11 at a distance ka (k greater than or equal to 1 and less than n) from the rotation center point O is πka 2 , the corresponding display times is mk / n, and the area displayed each time is πna 2 / m. Similarly, by adopting the display method provided by the embodiment of the present invention to drive the rotating display device to perform rotating display, the areas of single light-emitting display of any two light-emitting units 11 on the display component are the same, so that the actual pixel points of the rotating display device are evenly distributed, avoiding the problem of crosstalk and ghosting between pixels due to the over-dense display of the light-emitting units 11 close to the rotation center point O, and reducing power consumption loss.

[0052] In the above three embodiments, the rotation center point O is located in the middle of the single light bar 10. In other embodiments, the rotation center point O may also be located at the end of the single light bar 10. The display method of the rotating display is similar to that in the above three embodiments, and the details may refer to the above embodiments, which will not be described again.

[0053] Furthermore, the single light bar 10 can also perform translational motion perpendicular to the single light bar and the rotation direction, so as to achieve a three-dimensional display, and the three-dimensional display includes but is not limited to a cylindrical display.

[0054] The rotation display method further includes:

[0055] Before the rotational display is performed, according to the above-mentioned display principle of the rotational display method, the data signal of the picture to be displayed is divided into data signals corresponding to actual pixels; specifically, the color data, grayscale data, etc. contained in the picture to be displayed are divided into data signals corresponding to actual pixels, that is, divided into data signals corresponding to segments of circular areas, and the data signals are stored in a storage device.

[0056] When the rotation display method is executed on the rotation display device, the data signal is parsed and output to drive the corresponding light emitting unit.

[0057] Embodiment 2

[0058] Please refer to Figure 4 The display component of the rotating display device is a multi-light bar 20, and the multi-light bar includes at least two rows of light-emitting units 21, Figure 4 In the figure, three rows of the light-emitting units 21 are taken as an example for explanation. Similarly, the rotating display device has a rotation center point O, and the light-emitting units 21 rotate around the rotation midline point O with the rotation center point O as the center. The spacing between the light-emitting units 21 in two adjacent rows is the same, and the light-emitting units 21 are staggered in the direction perpendicular to the row. Assuming that the number of the light-emitting units 21 is 2n+1, one light-emitting unit 21 is set on the rotation center point O, n light-emitting units 21 are set on the left side of the rotation center point O, and n light-emitting units 21 are set on the right side of the rotation center point O. The light-emitting units 21 are symmetrically arranged on the left and right sides of the rotation center point O, and the distances between the light-emitting units 21 and the rotation center point O are a, 2a, 3a...na, respectively.

[0059] The display method of the rotating display device provided by the embodiment of the present invention includes:

[0060] In one rotation cycle, the display times of the light-emitting unit 21 whose distance from the rotation center point O is na is m, the display times of the light-emitting unit 21 whose distance from the rotation center point O is ka is mk / n, and the display times of the light-emitting unit 21 located at the rotation center point O is 1; wherein k is an integer greater than or equal to 1 and less than n.

[0061] Referring to the display principle of the first embodiment, within one rotation cycle, the light-emitting area of ​​the outermost light-emitting unit 21 is πna2, the corresponding display times are m, and the area displayed each time is πna2 / m; the light-emitting area of ​​the light-emitting unit 21 at a distance ka (k is greater than or equal to 1 and less than n) from the rotation center point O is πka2, the corresponding display times are mk / n, and the area displayed each time is πna2 / m. Similarly, by adopting the display method provided in the embodiment of the present invention to drive the rotating display device for rotational display, the areas of single light-emitting display of any two light-emitting units 21 on the display component are equal, so that the actual pixel points of the rotating display device are evenly distributed, avoiding the problem of crosstalk and ghosting between pixels due to the over-dense display of the light-emitting units 21 close to the rotation center point O, and reducing power consumption loss.

[0062] When the number of the light emitting units 21 is 2n, please refer to the first and second implementation schemes in Example 1, which will not be described in detail here.

[0063] This embodiment sets the light-emitting units 21 on the multi-light strips to be equidistant from the rotation center point O, thereby reducing the position deviation between the preset pixels and the actual pixels in the rotating display, resulting in vacant or overlapping pixels, and further improving the problems of uneven display and crosstalk of the rotating display device.

[0064] Embodiment 3

[0065] Please refer to FIG. 5(a) and FIG. 5(b). The display component of the rotating display device is a display panel 30. The display panel can be a circular display panel (as shown in FIG. 5(a)) or a rectangular display panel (as shown in FIG. 5(b)). The display panel 30 includes a plurality of rows of light-emitting units 31. The rotating display device has a rotation axis AA', and the display panel 30 rotates around the rotation axis AA'. The light-emitting units 31 are symmetrically distributed on both sides of the rotation axis AA' and are arranged at equal intervals in directions perpendicular to and parallel to the rotation axis AA'. In the circular display panel, the rotation axis AA' overlaps with the diameter of the circular display panel. In the rectangular display panel, the rotation axis AA' overlaps with the center line of the display panel, or overlaps with one side of the display panel, or overlaps with the outermost row or column of the light-emitting units of the display panel.

[0066] The direction perpendicular to the rotation axis AA' is the row of the light emitting units 31, and a row of the light emitting units 31 in the display panel 30 can be regarded as the single light bar 10 in the first embodiment, and the intersection of the rotation axis AA' and the row of the light emitting units 31 can be regarded as the rotation center point O in the first embodiment. Then, the display method and display principle of the circular display panel 30 can refer to the first embodiment above, and will not be repeated here.

[0067] Similarly, by adopting the display method provided by the embodiment of the present invention to drive the rotating display device to perform rotating display, the problem of crosstalk and ghosting between pixels caused by the over-dense display of the light-emitting units 31 close to the rotation axis AA' is avoided, and power consumption loss is reduced. The circular display panel provided by this embodiment realizes uniform spherical display, and the rectangular display panel provided by this embodiment realizes uniform cylindrical display.

[0068] In summary, an embodiment of the present invention provides a rotational display method for driving a rotational display device for rotational display. The rotational display method adjusts the display times of the light-emitting units, thereby adjusting the actual number of pixels in each layer outside the rotation center, so that the areas displayed by any two light-emitting units at a single time are equal, so that the actual pixel points of the rotational display device are evenly distributed, avoiding the problems of crosstalk and ghosting between pixels due to the over-dense display of the light-emitting units close to the rotation center, and reducing power consumption losses.

[0069] The above is a detailed introduction to the rotating display method provided in the embodiment of the present invention.
