[0066] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, rather than all of them. Usually, the components of the embodiments of the present disclosure described and illustrated herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the claimed present disclosure, but merely represents selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present disclosure.

[0067] Unless otherwise defined, the technical terms or scientific terms used in this disclosure shall have the ordinary meanings as understood by those of ordinary skill in the art to which this disclosure pertains. The terms "first", "second" and similar terms used in this disclosure do not denote any order, quantity or importance, but are only used to distinguish different components. Similarly, terms such as "a", "an" or "the" do not denote a quantity limitation, but mean that there is at least one. Terms such as "comprising" or "including" mean that the elements or items appearing before this term cover the elements or items listed after this term and their equivalents, without excluding other elements or items.

[0068] As used in this disclosure, "a plurality or several" means two or more. "And / or" describes the association relationship of associated objects and indicates that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally means that the associated objects before and after are in an "or" relationship.

[0069] In the related art, a display device includes a display panel and a plurality of prisms disposed on a side of the display panel close to the display surface. The display device includes a backlight source located on a side of the display surface facing away from the prisms. The light emitted by the backlight source passes through the display panel and then enters the human eye through the prisms. Among them, the prisms are configured to be able to change the propagation direction of the incident light.

[0070] In the application scenario of a large-size display screen, no matter where the human eye is in front of the screen, when the viewer watches the screen, there is always a large viewing angle situation. For example, when the human eye is directly opposite the center position of the display panel, the actual light path of the light emitted by the pixels at the edge of the display panel entering the human eye belongs to the large viewing angle situation. Another example is that when the human eye is directly opposite the left edge of the display panel, the actual light path of the light emitted by the pixels at the right edge of the display panel entering the human eye also belongs to the large viewing angle situation. Or, the human eye is not correspondingly arranged with the display area of the display panel. For example, when the human eye is located to the left of the left edge of the display panel, the larger the angle between the actual light path of the light emitted by the pixels farther away from the left edge in the display panel entering the human eye and the light path perpendicular to the display panel, that is, the larger the viewing angle.

[0071] For a naked-eye 3D display screen, when the light emitted by it enters the human eye directly, the 3D display effect experienced by the human eye is better; conversely, the more the light emitted by a certain pixel deviates from the light perpendicular to the display panel, that is, the larger the viewing angle, the worse the 3D display effect experienced by the human eye at the position of this pixel. Therefore, limited by the actual light path of the large-angle light emitted by the screen entering the human eye, the 3D display effect at the edge of the screen is often poor.

[0072] In view of this, the present disclosure provides a display method, which obtains the human eye position information by real-time detection, and fully considers the actual light path of light incident on the human eye at different angles according to the position relationship between the human eye coordinates indicated by the human eye position information and the positions of the pixels in the display panel. By pre-storing different groups of change rate sequences, a target group of change rate sequences matching the current human eye coordinates is selectively and specifically selected, and the first change rate corresponding to each target sequence in the target group of change rate sequences is used to more accurately determine the size information of the viewport corresponding to each target sequence, so as to more precisely calculate the position information of the viewport corresponding to the large viewing angle of the human eye, and perform subsequent pixel interleaving through the accurate viewport position information to improve the 3D display effect of the large-size display panel.

[0073] The display method provided by the embodiments of the present disclosure will be described in detail below.

[0074] In a first aspect, the embodiments of the present disclosure provide a display method, which is mainly applied to a display device; the display device includes a display panel and a plurality of prisms arranged on the side of the display panel close to the display surface.

[0075] Exemplarily, the display panel of the present disclosure may be a liquid crystal display (LCD) panel; alternatively, it may also be an organic light-emitting diode (OLED) panel.

[0076] Exemplarily, the display panel includes a plurality of pixels arranged in an array.

[0077] Figure 1 A schematic diagram of an exemplary display method provided by the present disclosure is shown in Figure 1 As shown, the display method includes steps S11 to S14, where:

[0078] S11. Generate first image data adapted to the left eye and second image data adapted to the right eye based on the received video signal.

[0079] Among them, the video signal is, for example, a signal of an image to be displayed on the display panel. Exemplarily, the resolution of the image to be displayed is, for example, 8K, that is, 7680×4320 pix. Exemplarily, the format of the video signal is, for example, SIDE-BY-SIDE.

[0080] Specifically, using an image segmentation algorithm, the image to be displayed corresponding to the video signal is segmented into a left image adapted to the left eye and a right image adapted to the right eye. Among them, the resolution of the left image is 4K, that is, 4096×2160pix; the resolution of the right image is 4K, that is, 4096×2160pix. Stretch the left image into an 8K image to obtain the first image data, and stretch the right image into an 8K image to generate the second image data.

[0081] S12. For any target row pixel, based on the obtained human eye position information, use a preset algorithm to determine the viewpoint map position information corresponding to the target row pixel.

[0082] Among them, the target row pixel is a certain row pixel in the multiple rows of pixels arranged in an array on the display panel.

[0083] Figure 2 It is a schematic diagram of the 3D module coordinate system provided by the embodiments of the present disclosure. Figure 3 It is a schematic diagram of the equivalent movement of the human eye provided by the embodiments of the present disclosure.

[0084] As Figure 2 and Figure 3 shown, the human eye position information is the coordinate of the human eye in the first space coordinate system, which can be obtained by a shooting device in real time to obtain an image related to the human eye, such as a face image, and determine the human eye position information by extracting the human eye features on the face image. The first space coordinate system is a pre-established 3D module coordinate system, where the extension direction of the first coordinate axis X is the row direction of the pixels arranged in an array, the extension direction of the second coordinate axis Y is the column direction of the pixels arranged in an array, and the extension direction of the third coordinate axis Z is the direction perpendicular to the display panel and pointing to the display surface side. The first coordinate value is the coordinate value under the first coordinate axis X, the second coordinate value is the coordinate value under the second coordinate axis Y, and the third coordinate value is the coordinate value under the third coordinate axis Z. The human eye coordinate indicated by the human eye position information is denoted as (X0, Y0, Z0). The origin O of the first space coordinate system is the center point of the display area of the display panel.

[0085] The specific process of executing the preset algorithm includes the following steps S121 to S123:

[0086] S121. Based on the human eye position information and the preset equivalent movement strategy, determine the equivalent movement position information.

[0087] In this step, the preset equivalent movement strategy may be a strategy of translating the eye coordinates indicated by the eye position information in the direction of the attachment angle of the prism and parallel to the OXY plane in the first spatial coordinate system of the display panel to the center of the target row pixels. In this way, starting from the current eye coordinates (X0, Y0, Z0), move according to the indication of the preset equivalent movement strategy to determine the finally moved position, that is, the position (X1, Y1, Z1) indicated by the equivalent movement position information.

[0088] Exemplarily, based on the first coordinate value and the second coordinate value in the eye position information, the attachment angle of the prism, the size information of the pixels, the resolution of the screen, and the number of rows of the preset row pixels, determine the first coordinate value in the equivalent movement position information; based on the second coordinate value in the eye position information, the size information of the pixels, the resolution of the screen, and the number of rows of the preset row pixels, determine the second coordinate value in the equivalent movement position information; use the third coordinate value in the eye position information as the third coordinate value in the equivalent movement position information.

[0089] Among them, both the length and width of the pixels indicated by the pixel size information are PW; the screen resolution is 7680×4320 pix.

[0090] The preset row pixels and the target row pixels belong to different row pixels respectively. Taking the preset pixel row as the first row as an example, the process of determining the first coordinate value X1, the second coordinate value X2, and the third coordinate value X3 in the equivalent movement position information is shown in the following formula (1):

[0091]

[0092] Among them, X1 represents the first coordinate value in the equivalent movement position information; Y1 represents the second coordinate value in the equivalent movement position information; Z1 represents the third coordinate value in the equivalent movement position information; X0 represents the first coordinate value in the eye position information; Y0 represents the second coordinate value in the eye position information; Z0 represents the third coordinate value in the eye position information; PW represents the size of the pixel, including the length under the first coordinate axis and the width under the second coordinate axis, and the length and width are equal; α represents the attachment angle of the prism; in the case of a screen resolution of 7680×4320 pix, 2196 represents half of the vertical pixels, that is, the first row of pixels, the center of the first row of pixels is 2195.5, and the second coordinate value of the center of the first row of pixels is 2159.5×PW.

[0093] S122. Based on the equivalent movement position information, the pre-stored prism parameters, and the pre-stored set of change rates, determine the viewport size information corresponding to each target sequence.

[0094] Exemplarily, the execution subject of the display method of the present disclosure is, for example, a driving device. The driving device pre-stores prism parameters and screen parameters. Among them, the prism parameters may include the prism pitch and the distance between the prism and the pixel. The prism pitch can be understood as the distance between the centers of two adjacent prisms in the row direction. The distance between the prism and the pixel can be understood as the vertical distance between the surface of the prism close to the pixel and the surface of the pixel close to the prism.

[0095] Exemplarily, the set of change rates is shown in Table 1 below. The set of change rates includes a group of change rate sequences corresponding to the position information of different human eyes respectively. Each group of change rate sequences includes a plurality of first change rates stored in sequence, which characterize the change in the size of the viewport.

[0096] It should be noted that the viewport corresponds to the prism one by one. The viewport is a series of arranged virtual images formed by the connection lines between the human eye coordinates and the boundary positions of each prism projected onto the pixel surface. A single viewport represents the minimum unit left view and right view that enter the human eye.

[0097] Specifically, the third coordinate value Z0 in the position information of different human eyes corresponds to different groups of change rate sequences.

[0098] Table 1

[0099]

[0100] The first change rates corresponding to each sequence 0-4095 in the above groups of change rate sequences are obtained through experiments under the condition of the third coordinate value Z0 of different human eye coordinates. They respectively correspond to the first change rates of 0-4095 sequences in different intervals of the third coordinate value Z0.

[0101] Specifically, first, based on the third coordinate value, the prism pitch, and the distance between the prism and the pixel in the equivalent movement position information, the size of the standard viewport can be calculated, that is, the standard size information of the standard viewport; second, based on the first change rates corresponding to each target sequence in the target group of change rate sequences and the standard size information, the viewport size information corresponding to each target sequence is determined.

[0102] The prism perpendicular to the display panel in the human eye coordinates is denoted as prism M. The standard viewport refers to the viewport formed by the projection of the connection line between the human eye coordinates and the boundary of prism M onto the display panel. The standard size information corresponding to the standard viewport is denoted as ΔX. The standard size information ΔX represents the length of the standard viewport, and this length can be understood as the length of the viewport in the extension direction of the first coordinate axis in the second space coordinate system.

[0103] For the specific process of determining the standard size information, refer to Formula 2:

[0104]

[0105] Among them, ΔX represents standard dimension information; LED_P represents the prism pitch; Z1 represents the third coordinate value in the equivalent movement position information; LED_H represents the distance between the prism and the pixel.

[0106] The determination process of the target change rate sequence group can be as follows: Based on the third coordinate Z0 in the human eye position information, a change rate sequence group corresponding to the third coordinate Z0 can be found from the change rate set, denoted as the target change rate sequence group. Or, based on the third coordinate value Z1 in the equivalent movement position information, a change rate sequence group corresponding to the third coordinate Z1 can be found from the change rate set, denoted as the target change rate sequence group COEm, where m is an integer from 0 to 7.

[0107] The view point map dimension information represents the length of the corresponding view point map, and this length can be understood as the length of the view point map in the extension direction of the first coordinate axis in the second space coordinate system.

[0108] For the specific process of determining the view point map dimension information corresponding to each target sequence (i.e., 0 to 4095), refer to Formula 3:

[0109]

[0110] Among them, ΔX0 represents the view point map dimension information corresponding to the target sequence COEm_0; ΔX1 represents the view point map dimension information corresponding to the target sequence COEm_1; ΔX4095 represents the view point map dimension information corresponding to the target sequence COEm_4095; ΔX represents the standard dimension information.

[0111] S123. Determine the view point map position information based on the equivalent movement position information, each view point map dimension information, the pre-stored prism parameters, and the pre-stored screen parameters.

[0112] First, it is necessary to set the serial number of the view point map corresponding to the equivalent movement position information to 0. On this basis, determine the distribution of the view point map in the second space coordinate system (such as Figure 4 or Figure 5As shown in the figure (i.e., sequence distribution information), including the serial numbers of the viewport maps corresponding to each prism. The second spatial coordinate system includes a first coordinate axis X' and a second coordinate axis Z', and an origin O' where the first coordinate axis X' and the second coordinate axis Z' intersect; the extending direction of the first coordinate axis X' is the row direction of the target row pixels, the second coordinate axis Z' is perpendicular to the first coordinate axis X' and perpendicular to the display surface, and the origin O' is at the edge position where the pixel at the outermost edge of the target row pixels in the row direction is far from the adjacent column pixels. In the figure, an example is given where the origin O' of the second spatial coordinate system is located at the left boundary of the target row pixels. The case where the origin of the second spatial coordinate system is located at the right boundary of the target row pixels is the same as the case of the left boundary, and the present disclosure will not list it again.

[0113] Secondly, it is necessary to determine the focal position information of the focal point. The focal point is the point where the optical path of the equivalent position of the human eye passes through the prism adjacent to the second coordinate axis and is transmitted to the reference plane where the target row pixels are located. Finally, based on the serial numbers of the viewport maps in the sequence distribution information, the viewport size information corresponding to each target sequence, and the focal position information, determine the viewport position information corresponding to the target row pixels.

[0114] The specific process of determining the viewport position information includes steps S1231 to S1233, where:

[0115] S1231. Based on the first coordinate value in the equivalent movement position information, the length of the display area, and the prism pitch, determine the sequence distribution information of the viewport maps in the second spatial coordinate system.

[0116] Specifically, the serial number of the viewport map corresponding to the equivalent movement position information can be directly set to 0. Based on this, it can be known that the viewport size information of the viewport map corresponding to the serial number 0 is ΔX0. It should be noted that the prism perpendicular to the display panel where the equivalent movement position is located is denoted as prism M', and the viewport map corresponding to the equivalent movement position information refers to the viewport map formed by the projection of the connection line between the equivalent movement position coordinates and the boundary of prism M' on the display panel.

[0117] After that, based on the first coordinate value in the equivalent movement position information, the length of the display area, and the prism pitch, determine that the serial number of the viewport map corresponding to the prism adjacent to the origin of the second spatial coordinate system on the target row pixels is K, as shown in the following formula four:

[0118]

[0119] Where K represents the serial number of the viewport map corresponding to the prism adjacent to the origin of the second spatial coordinate system on the target row pixels; ROUNDDOWN() represents rounding down; X1 represents the first coordinate value in the equivalent movement position information; PAN_H represents the length of the display area; LEN_P represents the prism pitch.

[0120] Based on the determined view point image of sequence number K, it is known that the view point image size information of the view point image corresponding to the sequence number K is ΔX(K).

[0121] After that, based on the arrangement order of the view point image of sequence number 0 and the view point image of sequence number K, determine the sequence numbers of the view point images corresponding to each prism. As Figure 4 or Figure 5 shown, it is set that the distribution of the sequence numbers of the view point images on the right side of the view point image of sequence number 0 is symmetric to the distribution of sequence numbers 0 to K, and when the number of view point images on the right side of the view point image of sequence number 0 is greater than K, they increase in sequence. For example, the view point images of sequence numbers 0 and K have been determined. According to the arrangement order, along the direction of the first coordinate axis X' from the origin O', they are successively the view point image of sequence number K - 1, the view point image of sequence number K - 2,..., the view point image of sequence number 0, the view point image of sequence number 1,..., the view point image of sequence number n, where n can take positive integers less than or equal to 4095. After determining the sequence numbers of each view point image and their distribution, based on the view point image size information [ΔX0, ΔX1, ……, ΔX4095] corresponding to each target sequence calculated by formula three, it is known the view point image size information of the view point images (0 to K, 0 to n) corresponding to each prism on the target row pixels.

[0122] S1232. Determine the focal position information based on the first coordinate value and the third coordinate value in the equivalent movement position information, the prism pitch of the prism, and the length of the display area.

[0123] The focal position information is the first coordinate value of the focus in the second space coordinate system.

[0124] Figure 4 It is a schematic diagram of the actual light path for an angle of light to enter the human eye provided by an embodiment of the present disclosure. Figure 5 It is another schematic diagram of the actual light path for an angle of light to enter the human eye provided by an embodiment of the present disclosure. As Figure 4 or Figure 5 shown, using the principle of similar triangles, the process of determining the focal position information is shown in formula five:

[0125]

[0126] Among them, X_star represents the first coordinate value of the focus in the second space coordinate system, that is, the focal position information; X1 represents the first coordinate value in the equivalent movement position information; PAN_H represents the length of the display area; Z1 represents the third coordinate value in the equivalent movement position information; LEN_H represents the prism pitch.

[0127] S1233. Determine the viewport position information corresponding to each prism based on the sequence numbers of each viewport in the sequence distribution information, the viewport size information corresponding to each target sequence, and the focal position information.

[0128] When the relative position relationship between the equivalent eye position indicated by the equivalent movement position information and the display area is different, the method for determining the viewport position information is different.

[0129] Specifically, based on the first coordinate value in the equivalent movement position information and the length of the display area, determine the relative position relationship between the equivalent eye position indicated by the equivalent movement position information and the display area. For example, determine whether X1 - PAN_H / 2 is greater than 0; if so, determine that the equivalent movement position information is within the display area; if not, determine that the equivalent movement position information is outside the display area.

[0130] Exemplarily, when it is determined that the equivalent movement position information is within the display area, use the focal position information as the viewport position information corresponding to the 1st prism; use the sum of the viewport position information corresponding to the i-th prism and the viewport size information of the viewport with the sequence number K - i + 1 as the viewport position information corresponding to the (i + 1)-th prism; i takes values from 1 to N, where N is a positive integer not less than K and not greater than 4095; among them, the i-th prism is closer to the second coordinate axis than the (i + 1)-th prism.

[0131] Here, the viewport position information of the viewport is the first coordinate value of the boundary of the viewport in the second spatial coordinate system. Specifically, taking the above second spatial coordinate system as an example, when it is determined that the equivalent movement position information is within the display area, the viewport position information is the first coordinate value of the left boundary of the viewport in the second spatial coordinate system. It should be noted that after determining the first coordinate value of the left boundary of the viewport, and according to the viewport size information (the length of the viewport) of the viewport, the first coordinate value of the right boundary of the viewport can be correspondingly determined, and then the actual area occupied by the viewport can be determined.

[0132] As Figure 4 shown, when it is determined that the equivalent movement position information is outside the display area, the process of determining the first coordinate value of the boundary of each viewport corresponding to the target row pixels in the second spatial coordinate system can be referred to formula six:

[0133]

[0134] Wherein, N is the number of single-line prisms on the target row pixels; EDGE_1 to EDGE_N respectively represent the first coordinate values of the left boundaries of 1 to N viewpoint images from the left boundary to the right boundary of the screen in the second space coordinate system. ΔX(K) to ΔX(0) and ΔX(0) to ΔX(n) belong to the data in the viewpoint image size information [ΔX0, ΔX1, ……, ΔX4095] corresponding to each target sequence.

[0135] As Figure 5 shown, when it is determined that the equivalent movement position information is outside the display area, the distance from the focus to the second coordinate axis is used as the viewpoint image position information corresponding to the first prism in the target row pixels; the sum of the viewpoint image position information corresponding to the i-th prism and the viewpoint image size information of the (K + i)-th serial number is used as the viewpoint image position information corresponding to the (i + 1)-th prism; i takes values from 1 to N, and N is a positive integer not less than K and not greater than 4095; wherein, the i-th prism is closer to the second coordinate axis than the (i + 1)-th prism.

[0136] Here, the viewpoint image position information of the viewpoint image is the first coordinate value of the boundary of the viewpoint image in the second space coordinate system. Specifically, taking the above second space coordinate system as an example, when it is determined that the equivalent movement position information is outside the display area, the viewpoint image position information is the first coordinate value of the right boundary of the viewpoint image in the second space coordinate system. It should be noted that by determining the first coordinate value of the right boundary of the viewpoint image and then according to the viewpoint image size information (the length of the viewpoint image) of the viewpoint image, the first coordinate value of the left boundary of the viewpoint image can be correspondingly determined, and then the actual area occupied by the viewpoint image can be determined.

[0137] When it is determined that the equivalent movement position information is outside the display area, the process of determining the first coordinate values of the boundaries of the viewpoint images corresponding to the target row pixels in the second space coordinate system is shown in Formula Seven:

[0138]

[0139] Wherein, N is the number of single-line prisms on the target row pixels; EDGE_1 to EDGE_N respectively represent the first coordinate values of the right boundaries of 1 to N viewpoint images from the left boundary to the right boundary of the screen in the second space coordinate system. ΔX(K + 1) to ΔX(K + N - 1) belong to the data in the viewpoint image size information [ΔX0, ΔX1, ……, ΔX4095] corresponding to each target sequence.

[0140] Following the above S12, then, based on the viewpoint image position information and the pixel position information of each sub-pixel obtained in the display screen, pixel interleaving is performed on the first image data and the second image data to generate a stereoscopic display picture. Specifically, refer to the following steps S13 and S14.

[0141] S13. Based on the viewport position information and the obtained pixel position information of each sub-pixel in the display panel, determine the position information of the left-eye pixels and the position information of the right-eye pixels.

[0142] The pixel position information of the sub-pixel can be the central position information of the center point of the sub-pixel. The central position information can be the first coordinate value of the center of the sub-pixel in the second space coordinate system.

[0143] The specific process of determining the pixel position information of each sub-pixel includes: for a target pixel in any target row of pixels, based on the position of the target pixel in the target row of pixels, the size information of the pixel, and the position of the sub-pixel in the target pixel, respectively determine the central position information of the red sub-pixel, the central position information of the green sub-pixel, and the central position information of the blue sub-pixel.

[0144] Among them, the position of the target pixel in the target row of pixels is also the number of the pixel in the target row of pixels. The size information of the pixel is the length of the pixel in the extension direction of the first coordinate axis of the second space coordinate system. The red sub-pixel, green sub-pixel, and blue sub-pixel in a single target pixel are arranged in sequence in the extension direction of the first coordinate axis of the second space coordinate system. Therefore, the position of the sub-pixel in the target pixel is known, that is, the red sub-pixel, green sub-pixel, and blue sub-pixel are in sequence along the extension direction of the first coordinate axis in the target pixel.

[0145] For example, taking the left boundary of the screen as the origin, calculate the central coordinates of the sub-pixels R, G, and B respectively, see Formula VIII:

[0146]

[0147] Among them, P_R_i represents the central position information of the red sub-pixel in the i-th target pixel in the target row of pixels; P_G_i represents the central position information of the green sub-pixel in the i-th target pixel in the target row of pixels; P_B_i represents the central position information of the blue sub-pixel in the i-th target pixel in the target row of pixels.

[0148] The process of specifically determining the position information of the left-eye pixels and the position information of the right-eye pixels includes: for any sub-pixel, based on the viewport position information corresponding to each prism and the pixel position information of the sub-pixel, determining that the sub-pixel is located between the position EDGE_v indicated by the viewport position information corresponding to the j-th prism and the position EDGE_(v + 1) indicated by the viewport position information corresponding to the (j + 1)-th prism; j is a positive integer and j is less than the total number of pixels in the target row; v + 1 is less than or equal to N; N is the number of single-row prisms on the target row pixels; when the position of the sub-pixel is in the first sub-interval, taking the position of the sub-pixel as the position information of the left-eye pixel; the range of the first sub-interval is between [EDGE_v, EDGE_v+(EDGE_(v + 1)-EDGE_v) / 2]; when the position of the sub-pixel is in the second sub-interval, taking the position of the sub-pixel as the position information of the right-eye pixel; the range of the second sub-interval is between [EDGE_v+(EDGE_(v + 1)-EDGE_v) / 2, (EDGE_(v + 1))].

[0149] S14. Generate a stereoscopic display screen based on the position information of the left-eye pixels, the first image data, the position information of the right-eye pixels, and the second image data.

[0150] Specifically, the image data of the sub-pixels corresponding to the positions in the first image data can be extracted according to the position information of the left-eye pixels, and the image data of the sub-pixels corresponding to the positions in the second image data can be extracted according to the position information of the right-eye pixels, so as to generate a stereoscopic display screen.

[0151] That is, if EDGE_v < P_R_i < EDGE_(v + 1) and P_R_i ≤ [EDGE_v+(EDGE_(v + 1)-EDGE_v) / 2], then the image data of the red sub-pixel located at the position P_R_i is extracted from the first image data; if EDGE_v < P_R_i < EDGE_(v + 1) and P_R_i > [EDGE_v+(EDGE_(v + 1)-EDGE_v) / 2], then the image data of the red sub-pixel located at the position P_R_i is extracted from the second image data, and they are interwoven to form a stereoscopic display screen, and the stereoscopic display screen is sent to the display panel for display. In addition, the extraction process of the image data at the positions of P_G_i and P_B_i is the same as that of P_R_i, and the repeated parts will not be described again.

[0152] For the convenience of understanding, the following uses a complete process to make an overall description of the display method provided by the embodiments of the present disclosure.

[0153] Exemplarily, Figure 6 is the specific flowchart of the display method provided by the embodiments of the present disclosure, as Figure 6As shown, it includes steps S21 to S210, where:

[0154] S21: Receive a video signal and simultaneously execute S24 for eye tracking to determine the eye position information in real time.

[0155] S22: Use an image segmentation algorithm to segment the image to be displayed corresponding to the video signal into a left image adapted to the left eye and a right image adapted to the right eye.

[0156] S23: Use an image stretching algorithm to stretch the left image to adapt to the screen resolution to obtain the first image data; stretch the right image to adapt to the screen resolution to obtain the second image data, and execute S28.

[0157] S24: Perform eye tracking to determine the eye position information in real time.

[0158] S25: Determine the parameters of the viewport diagrams, including the serial numbers of each viewport diagram, the viewport size information corresponding to each target sequence, and the distance from the focus to the second coordinate axis, etc.

[0159] S26: Determine the viewport diagram position information.

[0160] S27: Determine the position information of the left-eye pixels and the position information of the right-eye pixels.

[0161] S28: Perform pixel interleaving to determine the stereoscopic display screen.

[0162] S29: Transmit the stereoscopic display screen.

[0163] In the embodiments of the present disclosure, the eye position information is obtained through real-time detection. According to the positional relationship between the eye coordinates indicated by the eye position information and the pixels in the display panel (or according to the relative positional relationship between the equivalent eye position indicated by the equivalent movement position information and the display area), fully considering the actual light path of light incident on the eyes at different angles (as shown in Figure 4 and Figure 5 ), by pre-storing different groups of change rate sequences, the target group of change rates matching the current eye coordinates is selectively and specifically selected, and the first change rates corresponding to each target sequence in the target group of change rates are used to more accurately determine the viewport size information corresponding to each target sequence, so as to more precisely calculate the position information of the viewport diagrams corresponding to the large viewing angle of the eyes. Pixel interleaving is performed based on the accurate viewport diagram position information to improve the 3D display effect of the large-size display panel.
