[0002] Autostereoscopic 3D is an advanced display technology that allows users to see stereoscopic images directly with their naked eyes without wearing special glasses or head-mounted display devices. It uses precise optical design (such as parallax barriers, cylindrical lenses or directional light source technology) to project the left and right eye images onto the corresponding retinas, and uses the visual fusion principle of the human brain to generate a 3D effect with a sense of depth.

[0003] How to further promote the combined application of 3D naked-eye technology and various display panels and further expand the application areas and market of 3D naked-eye display is a technical problem that needs to be solved urgently. Summary of the invention

[0004] The present application provides a 3D display method, a 3D display control device and a 3D display equipment, which are conducive to promoting the combined application of 3D naked-eye technology and various display panels, and further expanding the application field and market of 3D naked-eye display.

[0005] In a first aspect, a 3D display method is provided, which is applied to a 3D display device. The 3D display device includes a display panel and a cylindrical lens array. The centers of sub-pixels of different colors in the display panel are not collinear. The display method includes: obtaining a viewpoint ordinal number of a first sub-pixel in the display panel, wherein a ratio of the viewpoint ordinal number to a preset total viewpoint number is equal to a ratio of a first distance to a first width, wherein the first distance is a distance between the first sub-pixel and an edge of a first lens in the cylindrical lens array in a first direction, the first width is a width of the first lens in the first direction, the first lens corresponds to the first sub-pixel, and the first direction is an arrangement direction of the cylindrical lens array; and controlling the first sub-pixel to display a corresponding viewpoint image according to the viewpoint ordinal number of the first sub-pixel in the display panel.

[0006] In the 3D display method provided in the embodiment of the present application, the viewpoint ordinal number of any sub-pixel can be determined when the centers of sub-pixels of different colors in the display panel are not collinear, thereby controlling the sub-pixel to display the corresponding viewpoint image. This solution can realize the correct arrangement of multiple sub-pixels or image interleaving methods and stereoscopic viewpoints in the display panel, and is not limited to the arrangement form of sub-pixels in the display panel, which is conducive to promoting 3D display to more types of display panels.

[0007] In some possible embodiments, obtaining the view point ordinal number of the first sub-pixel in the display panel includes: obtaining a first coordinate value of the center of the first sub-pixel relative to a target vertex in a display area of the display panel in a first direction, and a first width, where the target vertex is close to or aligned with an edge of the lenticular lens array; determining a first distance according to the first coordinate value and the first width; and determining the view point ordinal number according to the total number of view points, the first distance, and the first width.

[0008] In some possible embodiments, the display method further includes: obtaining an inclination angle between the lenticular lens array and a second direction, where the second direction is perpendicular to the first direction; obtaining a second coordinate value of the center of the first sub-pixel relative to the target vertex in the second direction; and determining the first distance according to the first coordinate value, the second coordinate value, the inclination angle, and the first width.

[0009] When the lens is inclined, it is beneficial to accurately guide light to different view points, and it is beneficial to reduce the periodic interference between the lens array and the pixel arrangement in the display panel, reduce moiré fringes. Further, it is also beneficial to optimize and balance the brightness uniformity of the center and edge view points and expand the viewing angle range.

[0010] In some possible embodiments, determining the first distance according to the first coordinate value, the second coordinate value, the inclination angle, and the first width includes: determining a first distance X according to a first formula, the first coordinate value x, the second coordinate value y, the inclination angle α, and the first width P x Determine the first distance X off , where the first formula is: X off =(x - y * tanα) mod P x .

[0011] In some possible embodiments, the display method further includes: obtaining an offset distance between an edge of the lenticular lens array and the target vertex in the first direction; and determining the first distance according to the offset distance, the first coordinate value, the second coordinate value, the inclination angle, and the first width.

[0012] In some possible embodiments, determining the first distance according to the offset distance, the first coordinate value, the second coordinate value, the inclination angle, and the first width includes: determining a first distance X according to a second formula, the offset distance w, the first coordinate value x, the second coordinate value y, the inclination angle α, and the first width P x Determine the first distance X off , where the second formula is: X off =(x + w - y * tanα) mod P x .

[0013] In the above embodiments, the lenticular lens array may be disposed in alignment with the display area of the display panel or may be offset, and in adaptation to these two setting schemes, the distance value of any sub-pixel in the display panel relative to the lens can be determined correspondingly according to the formula, and then the corresponding view point ordinal number can be accurately and quickly determined to achieve the correction of the stereoscopic graph.

[0014] In some possible embodiments, the display method further includes: obtaining the pixel width of the display panel, the sizes of multiple sub-pixels in a single pixel, the relative distance between multiple sub-pixels in a single pixel, and the pixel ordinal number of the pixel where the first sub-pixel is located, where the pixel ordinal number of the pixel where the first sub-pixel is located includes: the position ordinal number of the pixel where the first sub-pixel is located relative to the target vertex in the first direction and the position ordinal number in the second direction; determining a first coordinate value and a second coordinate value according to the pixel width, the sizes and relative distance of multiple sub-pixels, and the pixel ordinal number.

[0015] In this way, the two coordinate value components of the first sub-pixel can be relatively conveniently determined according to the relevant parameters of the pixel distribution in the display panel to determine the position of the first sub-pixel in the display panel, so as to determine the distance between the first sub-pixel and the corresponding first lens and obtain an accurate view point ordinal number. The calculation parameters of this method are easy to obtain and store, which is beneficial to further improving the performance of 3D display.

[0016] In some possible embodiments, the target vertex includes the upper left vertex of the display area, the lenticular lens array is set to be left-tilted, and the left edge of the lenticular lens array is close to or aligned with the upper left vertex of the display area; or, the target vertex includes the upper right vertex of the display area, the lenticular lens array is set to be right-tilted, and the right edge of the lenticular lens array is close to or aligned with the upper right vertex of the display area.

[0017] In this embodiment, the setting of the lenticular lens array can be relatively flexible, so as to be better adapted to the requirements of various display panels, which is beneficial to popularizing 3D display to more types of display panels.

[0018] In some possible embodiments, the display panel includes multiple pixels, and each pixel includes a red sub-pixel, a blue sub-pixel, and a green sub-pixel arranged in a triangle.

[0019] In 3D display, arranging or staggering the sub-pixels in a triangle can more efficiently utilize the screen space, reduce the resolution loss. In addition, it can also suppress moiré fringes, improve the viewing angle uniformity, and enhance the smoothness of the image transformation when switching the view point, which is beneficial to improving the 3D display effect.

The display control device includes: a processing unit configured to obtain the view point ordinal number of a first sub-pixel in the display panel, where the ratio of the view point ordinal number to the preset total number of view points is equal to the ratio of a first distance to a first width.

[0036] Next, the technical solutions in the present application will be described with reference to the accompanying drawings.

[0037] The present application relates to a display screen or also can be called a display panel. This display screen can be applied to various fields and scenarios. As an example, this display screen can be applied to 3C electronic products such as computers, communications, and consumer electronics, including but not limited to televisions, mobile phones, computers, laptops, tablets, personal digital assistants (PDAs), in-vehicle computers, wearable devices, gaming devices, shooting devices, etc. The present application does not limit the specific type of the electronic device where the display screen is located.

[0038] In addition, the display screen involved in the present application can be a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display screen, a low-temperature poly-silicon (LTPS) OLED display screen, an oxide OLED display screen, a micro (Mirco) OLED display screen, etc. The present application does not limit the specific type of the display screen.

[0039] This application further relates to naked-eye 3D display technology. As an example, Figure 1 The schematic diagram of a naked-eye 3D display device provided by an embodiment of this application is shown.

[0040] As Figure 1 shown, the naked-eye 3D display device 100 may include: a display panel 110 and a lens array 120. Among them, the lens array 120 is disposed on the light-emitting side of the display panel 110. The display panel 110 may include a plurality of pixels, and each pixel may include a plurality of sub-pixels of different colors. For example, it may include red sub-pixels, blue sub-pixels, and green sub-pixels. The lens array 120 may include a lenticular lens array, and this lenticular lens array can refract the images of different viewpoints displayed by the display panel 110 to the left and right eyes of the observer respectively, and form a three-dimensional sense through parallax. In the lenticular lens array, a plurality of lenticular lenses may be arranged along the x direction, and each lenticular lens may extend along the x' direction (not shown in the figure), and both the x' direction and the x direction are parallel to the display panel 110. In some examples, the x direction and the x' direction may be perpendicular to each other. The height direction of the lenticular lens is the z direction, and the z direction is perpendicular to the display panel 110. In the embodiments of this application, parameters such as the pitch, height, and radius of curvature of the lenticular lenses can jointly determine display parameters such as the number of viewpoints, distribution range, and resolution of the 3D display device.

[0041] During the 3D display process, after generating a multi-viewpoint image sequence, the multi-viewpoint images can be segmented and interleaved at the sub-pixel level, and the lenticular lenses project the light of different sub-pixels to the corresponding viewpoint positions, and the left and right eyes of the observer receive different images, thereby forming a stereoscopic vision.

[0042] In some examples, the plurality of sub-pixels in the display panel 110 are arranged in a regular array, and the center points of the plurality of sub-pixels are on a straight line. In other examples, the plurality of sub-pixels in the display panel 110 may also be arranged irregularly. For example, in a single pixel of the display panel 110, the center points of the plurality of sub-pixels are not on a straight line.

[0043] Figure 2 Another schematic diagram of the naked-eye 3D display device provided by an embodiment of this application is shown. This schematic diagram may be a schematic diagram along the xy plane, where the y direction is parallel to the display panel 110 and perpendicular to the x direction. Optionally, in this example, the lenticular lenses in the lens array 120 may extend along the y direction. In some embodiments, the x direction and the y direction may also be referred to as the horizontal direction and the vertical direction of the display panel 110.

[0044] As Figure 2As shown, in the autostereoscopic 3D display device 100, the display panel 110 may include a plurality of pixels 101 arranged in an array. In a single pixel 101, the sub-pixels of multiple different colors are not arranged in a regular array, and the center points of the sub-pixels of multiple different colors are not collinear. As an example, as shown in the figure, in a single pixel 101, three sub-pixels are arranged in a triangle. In 3D display, arranging sub-pixels in a triangular pattern or in a staggered distribution can make more efficient use of the screen space, reduce resolution loss. Additionally, it can suppress moiré fringes, improve the viewing angle uniformity, enhance the smoothness of image transformation during viewpoint switching, and is beneficial to improving the 3D display effect.

[0045] With the rapid development of display technology, display panels with irregularly arranged sub-pixels (such as OLED display panels) have been increasingly applied in various fields. The present application provides an autostereoscopic 3D display method (hereinafter also simply referred to as 3D display method) or an autostereoscopic 3D image interleaving method, which can provide a better autostereoscopic 3D display based on the display panel with irregularly arranged sub-pixels.

[0046] Figure 3 The figure shows a schematic diagram of a 3D display method provided by an embodiment of the present application. This display method can be applied to the autostereoscopic 3D display device described above Figure 1 and Figure 2 shown.

[0047] As Figure 3 shown, the 3D display method 200 may include the following steps.

[0048] S210, obtain the viewpoint ordinal number of the first sub-pixel in the display panel, where the ratio of the viewpoint ordinal number to the preset total number of viewpoints is equal to the ratio of the first distance to the first width. The first distance is the distance between the first sub-pixel and the edge of the first lens in the first direction in the lenticular lens array, the first width is the width of the first lens in the first direction, the first lens corresponds to the first sub-pixel, and the first direction is the arrangement direction of the lenticular lens array.

[0049] S220, control the first sub-pixel to display the corresponding viewpoint image according to the viewpoint ordinal number of the first sub-pixel in the display panel.

[0050] The display method provided by the embodiment of the present application can be executed by a 3D display control device, and the display control device may include, for example, a control chip or a processing chip and other chip devices with control or processing functions.

[0051] In S210, the first sub-pixel in the display panel can be any sub-pixel of the display panel, and the display control device can obtain the view point ordinal number of any sub-pixel in the display panel. In some examples, the view point ordinal number can be directly stored in the storage device, and the display control device can directly obtain the view point ordinal number from the storage device. Or, in other examples, the display control device can also obtain other types of data through the storage device or user input, and further determine the view point ordinal number through the calculation of this data.

[0052] Combined with Figure 2 and Figure 3 shown, an embodiment of the present application takes Figure 2 the sub-pixel 101a shown as an example of the first sub-pixel for illustration. In Figure 2 , the lens 120a (the first lens) corresponds to the sub-pixel 101a (the first sub-pixel), and at least a part of the sub-pixel 101a can be located in the projection of the lens 120a on the display panel 110. The display control device can obtain the distance X off (the first distance) between the center of the sub-pixel 101a and the edge of the lens 120a in the x direction (the first direction), the preset total number of view points N tot and the width P x (the first width) of the lens 120a in the x direction to determine the view point ordinal number N corresponding to the sub-pixel 101a, where the distance X off , the preset total number of view points N tot and the width P x of the lens 120a in the x direction and the view point ordinal number N corresponding to the sub-pixel 101a can satisfy the following formula (1):

[0053]

[0054] Wherein, the ratio of the view point ordinal number N to the total number of view points N tot is equal to the ratio of the distance X off to the width P x .

[0055] In S220, the display control device can further control the sub-pixel 101a to display the corresponding view point image according to the view point ordinal number N. The lens 120a can refract the optical signal emitted by the sub-pixel 101a to the view point N, so that the observer can observe the corresponding view point image at the view point N, forming a 3D display effect.

[0056] In the 3D display method provided by the embodiments of the present application, when the centers of different color sub-pixels in the display panel are not collinear, the view point ordinal number of any sub-pixel can be determined, so as to control the sub-pixel to display the corresponding view point image. This solution can realize the layout method or image interleaving method of multiple sub-pixels in the display panel and the correct arrangement of stereoscopic view points, and is not limited by the arrangement form of sub-pixels in the display panel, which is beneficial to popularize 3D display to more types of display panels.

[0057] Figure 4 Another schematic diagram of the naked-eye 3D display device provided by the embodiments of the present application is shown.

[0058] As Figure 4 shown, in the naked-eye 3D display device 100, the inclination angle between the lens array 120 and the y direction (the second direction) is α, where 0° ≤ α ≤ 15°. A plurality of lenses in the lens array 120 can be arranged in parallel, and the inclination angle between each lens in the lens array 120 and the y direction can be α.

[0059] When the lens is inclined, it is beneficial to accurately guide light to different view points, and is beneficial to reducing the periodic interference between the lens array and the pixel arrangement in the display panel, reducing moiré fringes. Further, it is also beneficial to optimize and balance the brightness uniformity of the center and edge view points and expand the viewing angle range.

[0060] In some embodiments, the display control device can obtain the coordinate values (x, y) of the center of the sub-pixel 101a relative to the target vertex O of the display area, the inclination angle α, and the width P of the lens 120a in the x direction x , and according to the coordinate values (x, y), the inclination angle α and the width P x , determine the distance X between the edge of the sub-pixel 101a and the lens 120a in the x direction off , and then according to the distance X off , the width P x and the total number of view points N tot , determine the view point ordinal number N of the sub-pixel 101a.

[0061] The above coordinate values (x, y), inclination angle α, width P x and the distance X off can satisfy the following formula (2):

[0062] X off = (x - y * tanα) mod P x (2);

[0063] Where P is the pitch of multiple lenses in the lens array 120. Both the coordinate value x and the coordinate value y are positive values, representing the distance values between the center of the sub-pixel 101a and the target vertex O in the x-direction and the y-direction, respectively.

[0064] Optionally, when the tilt angle is 0 as described above, the display control device may also not obtain the tilt angle, but obtain the coordinate value x of the center of the sub-pixel 101a relative to the target vertex O of the display area, and the width P of the lens 120a in the x-direction x , according to the coordinate value x and the width P x , determine the distance X between the sub-pixel 101a and the edge of the lens 120a in the x-direction off , and then according to the distance X off , width P x and the total number of viewpoints N tot , determine the viewpoint ordinal number N of the sub-pixel 101a. The coordinate value x, the width P x and the distance X off can satisfy the following formula (2’):

[0065] X off = x mod P x (2’).

[0066] In the embodiment of the present application, the target vertex O of the display area is close to or aligned with the edge of the lens array 120. For example, as Figure 4 shown, when the lens array 120 is tilted to the left, the left edge of the lens array 120 is aligned with the upper left corner of the display area. The edge of the leftmost lens in the lens array 120 intersects the upper left corner of the pixel in the first row and the first column. This display area may also be referred to as the Active Area (AA), abbreviated as the AA area. In this case, the upper left corner vertex of the display area can be referred to as the target vertex O, and the display control device can obtain the coordinate value of the center of any sub-pixel in the display panel relative to the target vertex O, and calculate the distance X between the sub-pixel and the edge of the corresponding lens in the x-direction off , and then according to the distance X off , lens width P x and the total number of viewpoints N tot , determine the viewpoint ordinal number N of the sub-pixel.

[0067] Figure 5 FIG. shows another schematic diagram of the naked-eye 3D display device provided by the embodiment of the present application.

[0068] As Figure 5As shown, in the autostereoscopic 3D display device 100, the edge of the lens array 120 is not aligned with the target vertex O in the display area, but has a certain offset in the x direction. As an example, the edge of the lens array 120 may be offset to the left by w1 or to the right by w2 relative to the target vertex O.

[0069] In this case, the display control device can obtain the offset distance w (w1 or w2), and obtain the coordinate values (x, y), tilt angle α, and the width P of the lens 120a in the x direction of the center of the sub-pixel 101a relative to the target vertex O in the display area x , and based on the offset distance w, coordinate values (x, y), tilt angle α, and width P x , determine the distance X in the x direction between the sub-pixel 101a and the edge of the lens 120a off , and then based on this distance X off , width P x , and the total number of viewpoints N tot , determine the viewpoint ordinal number N of the sub-pixel 101a.

[0070] The above offset distance w, coordinate values (x, y), tilt angle α, width P x , and distance X off can satisfy the following formula (3):

[0071] X off =(x + w - y * tanα) mod P x (3);

[0072] Wherein, when the edge of the lens array 120 is offset away from the display area relative to the target vertex O (for example Figure 5 as shown, the edge of the lens array 120 is offset to the left by w1 relative to the target vertex O), "w" in the above formula is a positive value (for example, w in the above formula is w1); when the edge of the lens array 120 is offset towards the display area relative to the target vertex O (for example Figure 5 as shown, the edge of the lens array 120 is offset to the right by w2 relative to the target vertex O), "w" in the above formula is a negative value (for example, w in the above formula is -w2).

[0073] Optionally, when the tilt angle is 0, the display control device may also not obtain the tilt angle, but obtain the offset distance w (w1 or w2), the coordinate value x of the center of the sub-pixel 101a relative to the target vertex O in the display area, and the width P of the lens 120a in the x direction x , and based on the offset distance w, coordinate value x, and width P x , determine the distance X in the x direction between the sub-pixel 101a and the edge of the lens 120a off . The coordinate value x, width Px and the distance X off can satisfy the following formula (3’):

[0074] X off =(x + w) mod P x (3’).

[0075] In the implementation manner of the above application embodiment, the display control device can obtain the coordinate values (x, y) of the center of the sub-pixel 101a relative to the target vertex O of the display area, and then calculate the distance X in the x direction between the sub-pixel 101a and the edge of the lens 120a off , and determine the view point ordinal number N of the sub-pixel 101a.

[0076] In some alternative implementation manners, the display control device can also obtain the pixel width of the display panel, the sizes of multiple sub-pixels in a single pixel, the relative distances between multiple sub-pixels in a single pixel, and the pixel ordinal number of the pixel where the sub-pixel is located, so as to determine the above coordinate values (x, y).

[0077] In this way, according to the relevant parameters of the pixel distribution in the display panel, the two coordinate value components of the first sub-pixel can be determined more conveniently to determine the position of the first sub-pixel in the display panel, so as to determine the distance between the first sub-pixel and the corresponding first lens, and obtain an accurate view point ordinal number. The calculation parameters of this method are easy to obtain and store, which is beneficial to further improving the performance of 3D display.

[0078] Figure 6 Shows another schematic diagram of the naked-eye 3D display device provided by the embodiment of the present application.

[0079] As Figure 6 shown, in the naked-eye 3D display device 100, the pixel width of the display panel 110 is P p , in a single pixel, three sub-pixels are arranged in a triangle, and the sizes and relative distances of the three sub-pixels are as shown in the figure. As an example, among the three sub-pixels, the length and width of the blue sub-pixel are b and g respectively, the length and width of the red sub-pixel are d and h respectively, and the length and width of the green sub-pixel are e and h respectively. The distance between the blue sub-pixel and the pixel edge in the x direction is a, the distances between the red sub-pixel and the green sub-pixel and the pixel edge in the x direction are f, and the distance between the two is 2f. The distance between the blue sub-pixel and the pixel edge in the y direction is f, and the distances between the blue sub-pixel and the red sub-pixel and the green sub-pixel are 2f. The distances between the red sub-pixel and the green sub-pixel and the pixel edge in the y direction are f.

[0080] The display control device can be based on the above a, b, d, e, f, g, h, P p, and the pixel ordinal numbers (u, v) of the pixel where any sub-pixel in the display panel 110 is located can determine the coordinate values (x, y) of the sub-pixel. The pixel ordinal numbers (u, v) can be used to represent the position ordinal number (column ordinal number) of the pixel in the x direction and the position ordinal number (row ordinal number) in the y direction respectively. For example, as Figure 6 shown, the pixel ordinal numbers (u, v) of the pixel where the sub-pixel 101a is located can be (4, 2), that is, the pixel where the sub-pixel 101a is located is the pixel in the 4th column and the 2nd row of the display panel 110.

[0081] In addition, the display control device can determine the width P of the lens 120a in the x direction according to the above pixel width P p , and the number of lines X. x . The pixel width P p , the number of lines X, and the width P of the lens 120a in the x direction x can satisfy the following formula (4):

[0082]

[0083] In some embodiments, Figure 6 the coordinate values (x B , y B ) of the blue sub-pixel with length and width b and g respectively can be calculated by the following formulas (5) and (6):

[0084] x B = u * P p - a - b / 2 (5);

For the sake of illustration, the centers of the sub-pixels of different colors shown in the figure are on the same straight line. In the application process, the arrangement of the sub-pixels of different colors in the same pixel can be as Figure 6 shown, in a triangular arrangement, or it can also be in other shaped arrangements, and the centers of the sub-pixels of different colors in the same pixel are not collinear.

In some other embodiments, each lens in the lens array 120 can also be tilted to the right, and the right edge of the lens array 120 is aligned with the upper right corner vertex of the display area of the display panel.

[0110] Figure 10 shows another schematic diagram of the naked-eye 3D display device provided by the embodiment of the present application.

[0111] As Figure 10As shown, in the autostereoscopic 3D display device 100, the target vertex O of the display area of the display panel 110 is the upper right corner vertex. The right edge of the lens array 120 is close to or aligned with the upper right corner vertex of the display area. The display control device can obtain the coordinate values (x, y) of the center of any sub-pixel in the display panel relative to the target vertex O, and calculate the distance X in the x direction between the sub-pixel and the edge of the corresponding lens. off , and then based on this distance X off , lens width P x , and the total number of viewpoints N tot , determine the viewpoint ordinal number N of the sub-pixel.

[0112] In the embodiments of the present application, the calculation of the distance X based on the coordinate values (x, y) and the calculation of the viewpoint ordinal number N based on the distance X off , lens width P off , and the total number of viewpoints N x can refer to the relevant methods and calculation formulas in the above tot -shown embodiments.

[0113] Figure 11 Another schematic diagram of the autostereoscopic 3D display device provided by the embodiments of the present application is shown.

[0114] As Figure 11 shown, in the autostereoscopic 3D display device 100, the arrangement and related parameters of each pixel and sub-pixel of the display panel 110 can refer to the relevant description of the embodiments shown in Figure 6 the above.

[0115] Based on the sub-pixel parameters a, b, d, e, f, g, h of the display panel 110, pixel width P p , and the pixel ordinal numbers (r, t) of the pixel where any sub-pixel in the display panel 110 is located, the coordinate values (x, y) of the sub-pixel can be determined. The pixel ordinal numbers (r, t) are used to represent the position ordinal numbers of the pixel in the x direction and y direction relative to the target vertex O in the display panel. For example, as Figure 11 shown, the pixel ordinal numbers (r, t) of the pixel where the sub-pixel 101a is located can be (4, 2).

[0116] Optionally, the pixel ordinal numbers (u, v) in the above Figure 6 -shown embodiments can be the default pixel ordinal numbers of the display panel. Based on the pixel ordinal numbers (u, v), the pixel ordinal numbers (r, t) in the embodiments of the present application can be determined. The conversion methods of the two pixel ordinal numbers can adopt the following formulas (17) and (18):

[0117] u = p - r + 1 (17);

[0118] v = t(18);

[0119] Where p is the number of columns of the display panel.

[0121] In some examples, when aligning at the right edge of the lens array or near the upper right corner vertex of the display area, the display control device can obtain the pixel ordinal number (u, v) of any pixel in the display panel, and convert the pixel ordinal number (u, v) into the pixel ordinal number (r, t) according to the above formulas (17) and (18), and then calculate the viewing point ordinal number N of the sub-pixel according to the pixel ordinal number (r, t).

[0125]

[0126] The viewing point ordinal number N of the green sub-pixel in the display panel can be determined by the following formula (21):

[0127]

[0128] As another possible implementation manner, when the edge of the lens array 120 is offset from the target vertex O away from the display area (offset distance w), it can be determined by the following formula (22) Figure 11 the viewing point ordinal number N of the blue sub-pixel in the shown display panel:

In some alternative embodiments, when a sub-pixel in the display panel is located at the edge of the lens, more accurate view point ordinal number calculation and image display control can be performed for this sub-pixel

[0135] Taking Figure 11 the sub-pixel 101b shown as an example, it is correspondingly located at the right edge of the lens 120a. The sub-pixel 101b is divided into two parts by the right edge of the lens 120a, and the view point ordinal numbers can be calculated separately for these two parts. Specifically, the view point ordinal number N corresponding to each part can be determined according to the distance X in the x direction between the center of each part and the right edge of the lens off , the preset total number of view points N tot and the width P of the lens in the x direction x . The sum of the gray level corresponding to the view point ordinal number of the left part multiplied by the area ratio of the left part and the gray level corresponding to the view point ordinal number of the right part multiplied by the area ratio of the right part can be determined as the gray level of this sub-pixel

For example, four sub-pixels are arranged in a diamond shape, etc. The embodiments of the present application do not make specific limitations on the arrangement manner of the multiple sub-pixels in the pixel

[0137] In addition, in the illustrations of the above embodiments, a single lens of the lens array is illustrated by taking covering two sub-pixels in the x direction as an example. In some alternative embodiments, the number of sub-pixels covered by the single lens in the x direction can be flexibly set according to actual needs, and the embodiments of the present application do not make specific limitations on this either
