[0064] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0066] Figure 1 A schematic diagram of the structure of a display device provided by an embodiment of the present invention, Figure 2 for Figure 1 Schematic diagram of color shift curve of the display device at various viewing angles, such as Figure 1 and Figure 2 As shown, in the near-eye display technology, in order to obtain a larger field of view (FOV), an optical magnification module 20, such as an optical machine, can be provided on the light-emitting surface of the display panel 10. The optical magnification module 20 collects light within different cone angles at different points of the display panel 10 and adjusts the light emission angle before emitting the light into the user's pupil, ensuring that the user can receive the light emitted by the display device. Figure 2 Shown in Figure 1 The changing trends of the viewing angle Viewangle and the color deviation value Δu'v' of the display device at 0° (curve 1), 90° (curve 2), 180° (curve 3) and 270° (curve 4) are shown in FIG. Figure 2As shown, the inventor has found through research that due to the microcavity effect and the four-corner optical crosstalk effect of the color resistor, the color deviation values of existing display devices at viewing angles greater than 20° are relatively large, resulting in color deviation problems in the displayed images when the display devices are applied to products such as Virtual Reality (VR), Augmented Reality (AR), or Electronic View Finder (EVF).

[0067] Based on the above technical problems, an embodiment of the present invention provides a method for zoned display of a display device. The display device includes a display panel and an optical magnification module disposed on the light-emitting side of the display panel. The method for zoned display includes: determining a color deviation control target of the display device according to the optical magnification module; determining the number of display zones of the display panel and the boundary light-receiving angles of each display zone according to the color deviation control target. Among them, the first display zone includes the center of the display panel, and the color deviation value at any light-receiving angle within the first display zone is less than the color deviation control target. The (p + 1)-th display zone surrounds the p-th display zone, and the difference between the color deviation value at any light-receiving angle within the (p + 1)-th display zone and the color deviation value at the boundary light-receiving angle of the p-th display zone is less than the color deviation control target. The boundary light-receiving angle of the N-th display zone is less than or equal to the maximum light-receiving angle of the optical magnification module. Among them, 1 ≤ p < N and both p and N are integers. Determining the gray-scale display voltage of the display zone according to the boundary light-receiving angle of the display zone; driving the display zone to display according to the gray-scale display voltage of the display zone. By adopting the above technical solution, the display panel is zoned according to the color deviation control target. The color deviation value at any light-receiving angle within the first display zone is less than the color deviation control target, and the difference between the color deviation value at any light-receiving angle within the (p + 1)-th display zone and the color deviation value at the boundary light-receiving angle of the p-th display zone is less than the color deviation control target. Then, the gray-scale display voltage of each display zone is determined according to the boundary light-receiving angle of each display zone, and each display zone is driven to display according to the gray-scale display voltage, so as to ensure that the display color deviation difference between adjacent display zones is less than the color deviation control target, ensure that the display color deviation difference between different display zones in the display device is small, and further ensure that the display color deviation of the display device is relatively balanced, improving the display effect of the display device.

[0068] The above is the core idea of the invention. Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0069] Figure 3 is a schematic flowchart of a method for zoned display of a display device provided by an embodiment of the present invention. In combination with Figure 1 and Figure 3 As shown in Figure 3 , the display device includes a display panel 10 and an optical magnification module 20 disposed on the light-emitting side of the display panel 10. Based on this structure, the zoned display method of the display device provided by the embodiments of the present invention includes:

[0070] Step S110: Determine the color deviation control target of the display device according to the optical magnification module.

[0071] Specifically, the color deviation generated by the display device is related to the specifications or parameters of the optical magnification module. Therefore, the color deviation control target of the display device can be determined according to the specifications or parameters of the optical magnification module, so that the color deviation control target matches the optical magnification modules with different specifications or parameters, ensuring that the display requirements of the display device are met.

[0072] Furthermore, the color deviation control target can be determined according to the color deviation display requirements, that is, the color deviation control target can be determined according to the color deviation display requirements. For example, when the accuracy requirement of the color deviation display is high, the color deviation control target can be set to be small; when the accuracy requirement of the color deviation display is low, the color deviation control target can be set to be large.

[0073] Step S120: Determine the number of display zones of the display panel and the boundary light-receiving angles of each display zone according to the color deviation control target.

[0074] Specifically, Figure 4 is a schematic structural diagram after zoning in a display device provided by an embodiment of the present invention. As Figure 4 shown, during the display process of the display device, the display panel can be zoned, and the display effect can be achieved based on the zoning. Furthermore, as Figure 4 shown, the first display zone S1 includes the center O of the display panel, the second display zone S2 surrounds the first display zone S1, the third display zone S3 surrounds the second display zone S2,..., and the (p + 1)-th display zone surrounds the p-th display zone. That is, as the number of the display zones increases, the display zone is farther and farther away from the center O of the display panel.

[0075] Furthermore, the color deviation value at any light-receiving angle within the first display zone is less than the color deviation control target. The (p + 1)-th display zone surrounds the p-th display zone, and the difference between the color deviation value at any light-receiving angle within the (p + 1)-th display zone and the color deviation value at the boundary light-receiving angle of the p-th display zone is less than the color deviation control target. The boundary light-receiving angle of the N-th display zone is less than or equal to the maximum light-receiving angle of the optical magnification module; where 1 ≤ p < N and both p and N are integers.

[0076] For example, since the optical amplification module needs to collect light within different cone angles at different points in the display panel, the center angle of the light collection cone can be understood as the light collection angle of the optical module, which can be expressed as CRA (Chief Ray Angle). Since the color deviation value at any light collection angle in the first display partition S1 is less than the color deviation control target, the display color deviation at any display position in the first display partition S1 is less than the color deviation control target, that is, the display color deviation at any point in the first display partition S1 meets the display color deviation requirement. Furthermore, since the light collection angle corresponding to the boundary position in each display partition S1 is the largest, combined with Figure 2 From the correspondence between the light output angle and the color deviation, it can be known that the display color deviation value corresponding to the display light at the boundary position is also the largest. In the embodiment of the present invention, since the difference between the color deviation value at any light receiving angle in the (p+1)th display partition and the color deviation value at the boundary light receiving angle of the pth display partition is less than the color deviation control target, the difference between the display color deviation at any display position in the (p+1)th display partition and the maximum color deviation value of the pth display partition is less than the color deviation control target, that is, the difference between the display color deviation of any point in the (p+1)th display partition and the maximum color deviation value of the pth display partition meets the display color deviation requirement. In this way, through the division of the display partitions, it can be ensured that the color deviation values ​​in different display partitions are all less than the color deviation control target, and the display color deviation differences between different display partitions are small, ensuring that the overall display color deviation balance of the display device is good.

[0077] It should be noted that if the Nth display partition satisfies the premise that the boundary light receiving angle is less than or equal to the maximum light receiving angle of the optical magnification module, and all edge display areas of the display panel are located within the Nth display partition, then the display panel includes a total of N display partitions, for example, the display panel is a circular display panel; if the Nth display partition satisfies the premise that the boundary light receiving angle is less than or equal to the maximum light receiving angle of the optical magnification module, there are some edge display areas located outside the Nth display partition, for example, the display panel is a non-circular display panel, then the display panel includes a total of (N+1) display partitions.

[0078] Step S130 : determining the grayscale display voltage of the display partition according to the boundary light collection angle of the display partition.

[0079] Specifically, according to the above-mentioned display partition division method, it is ensured that the display color deviation difference between different display partitions is small. Therefore, on the basis of the above-mentioned display partitions, the grayscale display voltage of each display partition can be determined, and then the display partition is driven to display by the grayscale display voltage corresponding to each display partition, which can ensure that the display color deviation difference between two adjacent display partitions is small.

[0080] It should be noted that if the display panel includes (N+1) display partitions, the grayscale display voltage of the (N+1)th display partition may be determined according to the maximum light receiving angle of the optical amplification module.

[0081] Step S140 , driving the display partition to display according to the grayscale display voltage of the display partition.

[0082] Specifically, the display partitions are driven according to the grayscale display voltages of different display partitions to ensure that the displayed image of each display partition matches the grayscale display voltage, to ensure that the display color deviation within each display partition and the display color deviation within the display partition are both within the color deviation control target, to ensure that the display color deviation differences within different display partitions are small, and to ensure that the display color deviation balance of the integrated display device is good.

[0083] To summarize, the partitioned display method provided in the embodiment of the present invention partitions the display panel according to the color deviation control target. The color deviation value at any light receiving angle in the first display partition is less than the color deviation control target, and the difference between the color deviation value at any light receiving angle in the (p+1)th display partition and the color deviation value at the boundary light receiving angle of the pth display partition is less than the color deviation control target. Then, the grayscale display voltage of each display partition is determined according to the boundary light receiving angle of each display partition, and the display partition is driven to display according to the grayscale display voltage. In this way, it is ensured that the display color deviation differences in adjacent display partitions are less than the color deviation control target, and the display color deviation differences between different display partitions in the display device are small, thereby ensuring that the display color deviation of the display device is relatively balanced, thereby improving the display effect of the display device.

[0084] Based on the above embodiments, Figure 5 is a flow chart of another partition display method provided by an embodiment of the present invention. Figure 5 The partition display method shown adds a step of determining the relationship between the color shift control target, the number of display partitions, and the boundary light collection angle of the display partitions on the basis of the above embodiment, so that the number of display partitions under any other color shift control target and the boundary light collection angle of different display partitions can be directly determined based on the relationship between the above three. Figure 5 As shown, the partition display method provided by the embodiment of the present invention includes:

[0085] Step S210: determining a color shift control target of the display device according to the optical amplification module.

[0086] Step S220: determining the number of display partitions of the display panel and the boundary light collection angle of each display partition according to the color shift control target.

[0087] Among them, the first display partition includes the center of the display panel, and the color deviation value at any light-receiving angle within the first display partition is less than the color deviation control target. The (p + 1)-th display partition surrounds the p-th display partition, and the difference between the color deviation value at any light-receiving angle within the (p + 1)-th display partition and the color deviation value at the boundary light-receiving angle of the p-th display partition is less than the color deviation control target. The boundary light-receiving angle of the N-th display partition is less than or equal to the maximum light-receiving angle of the optical magnification module; where 1 ≤ p < N and both p and N are integers.

[0088] Step S230: Determine the first correspondence relationship among the color deviation control target, the number of display partitions, and the boundary light-receiving angles of the display partitions.

[0089] Specifically, based on the specific values of the color deviation control target, the number of display partitions, and the boundary light-receiving angles of the display partitions obtained from the above embodiments, the correspondence relationship among the three can be obtained through mathematical operation methods. In this way, when adjusting the color deviation control target subsequently, there is no need to separately determine the number of display partitions and the boundary light-receiving angles corresponding to different display partitions according to the color deviation control target as in the above embodiments. Instead, the number of display partitions and the boundary light-receiving angles of different display partitions can be directly determined according to the first correspondence relationship among the color deviation control target, the number of display partitions, and the boundary light-receiving angles of the display partitions. The method for determining the number of display partitions and the boundary light-receiving angles in each display partition is simple.

[0090] Specifically, determining the first correspondence relationship among the color deviation control target, the number of display partitions, and the boundary light-receiving angles of the display partitions may include the following steps:

[0091] Determine the second correspondence relationship between the number of display partitions and the boundary light-receiving angles of the display partitions.

[0092] Determine the first correspondence relationship according to the second correspondence relationship.

[0093] Among them, the second correspondence relationship can satisfy: C = q * N; where C is the boundary light-receiving angle of the display partition and C is less than or equal to the maximum light-receiving angle of the optical magnification module, and q is a constant. That is, the boundary light-receiving angle is proportional to the number of display partitions. The larger the number of display partitions, the larger the boundary light-receiving angle corresponding to the display partition.

[0094] Among them, the first correspondence relationship satisfies: C = (i * s - j) * N; where s is the color deviation control target; both i and j are constants.

[0095] Step S240: Determine the number of display partitions and the boundary light-receiving angles of different display partitions under any other color deviation control target according to the first correspondence relationship.

[0096] In this way, according to the first corresponding relationship C=(i*sj)*N, when adjusting the color deviation control target, the number of display partitions of the display panel and the boundary light receiving angle corresponding to each display partition can be determined. The method for determining the number of display partitions and the boundary light receiving angle of each display partition is simple.

[0097] Step S250 , determining the grayscale display voltage of the display partition according to the boundary light collection angle of the display partition.

[0098] Step S260: driving the display partition to display according to the grayscale display voltage of the display partition.

[0099] Based on the above embodiments, a specific implementation method is used below to illustrate how to determine a first correspondence between a color shift control target, the number of display partitions, and the boundary light receiving angles of the display partitions, and determine the number of display partitions corresponding to the adjusted color shift control target and the boundary light receiving angles corresponding to different display partitions based on the first correspondence.

[0100] Taking the optical magnification module as an example, the maximum light receiving angle of the optical machine is 40°, and the maximum image height is 9.3mm. The image height can be understood as the distance from the center of the display panel. For example, an image height of 0 indicates the center position of the display panel; an image height of 9.3mm indicates an arc position with a distance of 9.3mm from the center position of the display panel, and the outgoing light at this position corresponds to the maximum light receiving angle of the optical machine.

[0101] According to the above method, it can be determined that the first corresponding relationship between the color shift control target s, the number of display partitions N, and the boundary light receiving angle C of the display partition satisfies C=(1284.8*–0.0503)*N, where C≤40° and N is a positive integer.

[0102] For example, when s=0.002, according to the first corresponding relationship, N is equal to 14 at most, and the boundary light collection angles of each display partition are shown in Table 1 below. The maximum display color deviation value of each display partition is <0.002.

[0109] According to the above table, the display panel can be divided into 6 display partitions, and the grayscale display voltage of each display partition can be obtained by performing a one-time program operation on each display partition.

[0110] To summarize, the partition display method provided in the embodiment of the present invention can determine the first correspondence between the color deviation control target, the number of display partitions and the boundary light receiving angles of the display partitions through reasonable mathematical operations on the basis of existing color deviation control targets, the number of display partitions and the boundary light receiving angles of different display partitions. Then, the number of display partitions corresponding to the adjusted color deviation control target and the boundary light receiving angles corresponding to different display partitions can be directly determined according to the first correspondence. The method for determining the number of display partitions and the boundary light receiving angles is simple, and then the grayscale display voltages of different display partitions are determined by determining the number of display partitions and the boundary light receiving angles of different display partitions. Then, the display is driven by the grayscale display voltages of different display partitions to ensure that the color deviation difference between different display partitions is less than the color deviation control target, to ensure that the display color deviation difference between different display partitions in the display device is small, and then to ensure that the display color deviation of the display device is relatively balanced, thereby improving the display effect of the display device.

[0111] Based on the above embodiments, Figure 6 is a flow chart of another partition display method provided by an embodiment of the present invention. Figure 6 The partition display method shown in the figure describes in detail how to determine the boundary light collection angles of different display partitions based on the above embodiments. Figure 6 As shown, the partition display method provided by the embodiment of the present invention includes:

[0112] Step S310: determining a color shift control target of the display device according to the optical amplification module.

[0113] Step S320: determining a boundary light collection angle of the first display subarea according to a color shift control target.

[0114] Specifically, determining the boundary light collection angle of the first display subarea according to the color shift control target may include the following steps:

[0115] Calculating a color deviation value of a first light receiving angle C1, where the color deviation value of the first light receiving angle C1 is less than a color deviation control target;

[0116] The light receiving angle is adjusted to a second light receiving angle C2 according to a preset angle step value, and the color deviation value of the second light receiving angle C2 is calculated until the color deviation value of the second light receiving angle C2 is greater than the color deviation control target; wherein C2=C1+x*a, a is the preset angle step value, and x is a positive integer;

[0117] The third light collection angle C3 is determined as the boundary light collection angle of the first display subarea, wherein C3=C1+(x-1)*a.

[0118] Specifically, when determining the boundary light receiving angle of the first display partition, a light receiving angle can be arbitrarily determined first. If the display color deviation at the light receiving angle is less than the color deviation control target, the light receiving angle can be confirmed as the first light receiving angle C1. If the display color deviation at the light receiving angle is greater than the color deviation control target, then based on the light receiving angle, the light receiving angle is adjusted down and the first light receiving angle C1 is re-determined. After determining the first light receiving angle C1, the value of the light receiving angle is gradually increased according to the preset angle step value, and the display color deviation corresponding to each light receiving angle is continuously calculated in the process of increasing the value of the light receiving angle until the second light receiving angle C2 is reached. The second light receiving angle C2 is the light receiving angle corresponding to the first light receiving angle where the display color deviation is greater than the color deviation control target; wherein, the second light receiving angle C2 satisfies C2=C1+x*a, where a is the preset angle step value and x is a positive integer. Since the second light receiving angle C2 is the light receiving angle where the display color deviation is greater than the color deviation control target for the first time, the third light receiving angle C3 which is smaller than the second light receiving angle C2 by a preset angle step value is the boundary light receiving angle of the first display partition, that is, C3=C1+(x-1)*a.

[0119] Step S330 , determining the boundary light collection angle of the (p+1)th display partition and the number of display partitions in the display panel according to the color shift control target, the boundary light collection angle of the pth display partition and the maximum light collection angle of the optical amplification module.

[0120] Specifically, determining the boundary light collection angle of the (p+1)th display partition and the number of display partitions in the display panel according to the color shift control target, the boundary light collection angle of the pth display partition, and the maximum light collection angle of the optical amplification module may include:

[0121] Calculate the color deviation value of the g-th light receiving angle Cg, the g-th light receiving angle Cg is greater than the boundary light receiving angle of the p-th display partition, and the difference between the color deviation value of the g-th light receiving angle Cg and the color deviation value of the boundary light receiving angle of the p-th display partition is less than the color deviation control target;

[0122] The light receiving angle is adjusted to the hth light receiving angle Ch according to the preset angle step value, and the color deviation value of the hth light receiving angle Ch is calculated until the difference between the color deviation value of the hth light receiving angle Ch and the color deviation value of the boundary light receiving angle of the pth display partition is greater than the color deviation control target; wherein, Ch=Cg+m*a, a is the preset angle step value, and m is a positive integer;

[0123] Determine the kth light collection angle Ck as the boundary light collection angle of the (p+1)th display subarea, where Ck=Cg+(m-1)*a;

[0124] The above steps are repeated until the boundary light collection angle of the Nth display partition is less than or equal to the maximum light collection angle of the optical amplification module, and the number of partitions of the display panel is determined to be N+1.

[0125] Specifically, after determining the boundary light receiving angle of the first display partition, the boundary light receiving angle of the second display partition can be determined based on the boundary light receiving angle of the first display partition, and then the boundary light receiving angle of the third display partition can be determined based on the boundary light receiving angle of the second display partition, and then the boundary light receiving angle of the fourth display partition can be determined based on the boundary light receiving angle of the third display partition, until the boundary light receiving angle of the Nth display partition is determined based on the boundary light receiving angle of the (N-1)th display partition.

[0126] Exemplarily, when determining the boundary light receiving angle of the (p+1)th display partition based on the boundary light receiving angle of the pth display partition and the maximum light receiving angle of the optical amplification module, a light receiving angle can be arbitrarily determined first. If the difference between the display color deviation at the light receiving angle and the display color deviation corresponding to the boundary light receiving angle of the pth display partition is smaller than the color deviation control target, then the light receiving angle can be confirmed as the gth light receiving angle Cg. If the difference between the display color deviation at the light receiving angle and the display color deviation corresponding to the boundary light receiving angle of the pth display partition is greater than the color deviation control target, then based on the light receiving angle, the light receiving angle is adjusted down and the gth light receiving angle Cg is re-determined. After determining the g-th light receiving angle Cg, the value of the light receiving angle is gradually increased according to the preset angle step value, and the display color deviation corresponding to each light receiving angle is continuously calculated in the process of increasing the value of the light receiving angle, until the h-th light receiving angle Ch, the h-th light receiving angle Ch is the difference between the display color deviation of the light receiving angle that appears for the first time and the display color deviation corresponding to the boundary light receiving angle of the p-th display partition, which is greater than the light receiving angle corresponding to the color deviation control target; wherein the h-th light receiving angle Ch satisfies Ch=Cg+m*a, a is the preset angle step value, and m is a positive integer. Since Ch=Cg+m*a is the difference between the display color deviation of the light receiving angle that appears for the first time and the display color deviation corresponding to the boundary light receiving angle of the p-th display partition, which is greater than the light receiving angle corresponding to the color deviation control target, the k-th light receiving angle Ck that is one preset angle step value smaller than the h-th light receiving angle Ch is the boundary light receiving angle of the (p+1)-th display partition, that is, Ck=Cg+(m-1)*a.

[0127] Repeat the above steps until the boundary light receiving angle of the Nth display partition is less than or equal to the maximum light receiving angle of the optical amplification module. Since the display panel is mostly a non-circular display panel, such as a rectangular display panel, the Nth display partition also includes part of the edge display area, so the number of partitions of the display panel can be determined to be N+1.

[0128] Step S340: determining the grayscale display voltage of the display partition according to the boundary light collection angle of the display partition.

[0129] Step S350: driving the display partition to display according to the grayscale display voltage of the display partition.

[0130] In summary, for the zoned display method provided by the embodiments of the present invention, the boundary light collection angles of different display zones and the number of display zones are determined through the above methods, which can ensure that the boundary light collection angles of the display zones and the number of display zones are accurately and correctly determined. Further, determining the grayscale display voltages of different display zones according to the boundary light collection angles of each display zone can ensure that the grayscale display voltages of each display zone are accurately and correctly determined. Then, by driving each display zone to display through the grayscale display voltages, the color deviation difference between different display zones is ensured to be less than the color deviation control target, the display color deviation difference between different display zones in the display device is ensured to be small, and further the display color deviation of the display device is ensured to be relatively balanced, improving the display effect of the display device.

[0131] Based on the above embodiments, Figure 7 FIG. is a schematic flowchart of another zoned display method provided by the embodiments of the present invention. Figure 7 The zoned display method shown in FIG. details how to determine the grayscale display voltages of different display zones based on the above embodiments. Specifically, as Figure 7 shown, the zoned display method provided by the embodiments of the present invention includes:

[0132] Step S410: Determine the color deviation control target of the display device according to the optical magnification module.

[0133] Step S420: Determine the number of display zones of the display panel and the boundary light collection angles of each display zone according to the color deviation control target.

[0134] Among them, the first display zone includes the center of the display panel, and the color deviation value at any light collection angle within the first display zone is less than the color deviation control target. The (p + 1)-th display zone surrounds the p-th display zone, and the difference between the color deviation value at any light collection angle within the (p + 1)-th display zone and the color deviation value at the boundary light collection angle of the p-th display zone is less than the color deviation control target. The boundary light collection angle of the N-th display zone is less than or equal to the maximum light collection angle of the optical magnification module; where 1 ≤ p < N and p, N are both integers.

[0135] Step S430: Determine the boundary image height corresponding to the boundary light collection angle of each display zone according to the correspondence between the light collection angle of the optical magnification module and the image height of the display panel.

[0136] Specifically, the light collection angle of the optical magnification module is positively correlated with the image height of the display panel, that is, the larger the image height of the display panel, the larger the light collection angle of the optical magnification module, and the smaller the image height of the display panel, the smaller the light collection angle of the optical magnification module.

[0137] The following table is a correspondence table between the light collection angle of a specific model of optical magnification module, such as an optical engine, and the image height of the display panel.

[0138] Table 3

[0140] It can be seen from the above table that there is a positive correlation between the light receiving angle of the optical magnification module and the image height of the display panel. The boundary image height corresponding to the boundary light receiving angle of each display partition can be determined based on the correspondence between the light receiving angle of the optical magnification module and the image height of the display panel.

[0141] Step S440: determining the central image height of the display partition according to the boundary image height.

[0142] Specifically, the central image height of the display partition may be understood as the image height corresponding to the central position of the display partition.

[0143] Specifically, determining the central image of the display partition according to the boundary image height may include the following steps:

[0144] Determine a center image height of the first display subarea according to a boundary image height of the first display subarea and an image height of a center of the display panel;

[0145] Determine the central image height of the (p+1)th display subarea according to the boundary image height of the (p+1)th display subarea and the boundary image height of the pth display subarea;

[0146] The central image height of the area outside the Nth display partition is determined according to the maximum image height of the display panel and the boundary image height of the Nth display partition.

[0147] Specifically, the image height at the center of the display panel is 0, and the central image height H1 ′ of the first display subarea is determined according to the boundary image height H1 of the first display subarea and the image height at the center of the display panel, where H1 ′=H1 / 2.

[0148] The central image height H(p+1)' of the (p+1)th display partition is determined based on the boundary image height H(p+1) of the (p+1)th display partition and the boundary image height Hp of the pth display partition, where H(p+1)'=(H(p+1)+Hp) / 2.

[0149] The central image height H(N+1)' of the area outside the Nth display partition is determined according to the maximum image height Hmax of the display panel and the boundary image height HN of the Nth display partition, where H(N+1)'=(Hmax+HN) / 2.

[0150] Step S450 , determining a central light collection angle corresponding to the central image height according to the correspondence between the light collection angle of the optical amplification module and the image height of the display panel and the central image height.

[0151] As described above, the light collection angle of the optical magnification module is positively correlated with the image height of the display panel, so the central light collection angle corresponding to the central image height in each display partition can be determined according to the central image height of the display partition.

[0152] Step S460 , performing a one-time program calculation according to the central light collection angle to determine the light collection angle of the display partition and determine the grayscale display voltage of the display partition.

[0153] Specifically, a one-time programmable (OTP) operation is performed according to the central light receiving angle of each display partition to obtain the grayscale display voltage corresponding to the central light receiving angle of each display partition, thereby ensuring that the grayscale display voltage matches the display partition well and the display effect of the display partition is good.

[0154] Step S470: driving the display partition to display according to the grayscale display voltage of the display partition.

[0155] In summary, the partition display method provided by the embodiment of the present invention determines the boundary image height corresponding to the boundary light collection angle of each display partition according to the correspondence between the light collection angle of the optical amplification module and the image height of the display panel, and then determines the center image height in the display partition through the boundary image height, and then determines the center light collection angle through the center image height, and finally performs a one-time program calculation through the center light collection angle to obtain the grayscale display voltage of the display partition and drives the display partition for display through the grayscale display voltage. The grayscale display voltage data is accurate, thereby ensuring that the color deviation difference between different display partitions is less than the color deviation control target, ensuring that the display color deviation difference between different display partitions in the display device is small, and improving the display effect of the display device.

Figure 8 As shown, the partition display method provided by the embodiment of the present invention includes:

[0157] Step S510: determining a color shift control target of the display device according to the optical amplification module.

[0158] Step S520: determining the number of display partitions of the display panel and the boundary light collection angle of each display partition according to the color shift control target.

[0159] Among them, the first display partition includes the center of the display panel, and the color deviation value at any light-receiving angle within the first display partition is less than the color deviation control target. The (p + 1)-th display partition surrounds the p-th display partition, and the difference between the color deviation value at any light-receiving angle within the (p + 1)-th display partition and the color deviation value at the boundary light-receiving angle of the p-th display partition is less than the color deviation control target. The boundary light-receiving angle of the N-th display partition is less than or equal to the maximum light-receiving angle of the optical magnification module; where 1 ≤ p < N and both p and N are integers.

[0160] Step S530: Under the conditions of the same color coordinates, the same gamma index, and the same target brightness, perform a one-time program operation on the display partition according to the light-receiving angle of the display partition.

[0161] Specifically, under the conditions of the same color coordinates, the same gamma index (such as gamma2.2), and the same target brightness, perform OTP on each display partition according to the light-receiving angle of the display partition, so as to ensure that the display effects corresponding to different display partitions are the same and the display uniformity of different display partitions of the display device is good.

[0162] Step S540: Determine the grayscale display voltage of each display partition according to the result of the one-time program operation.

[0163] Step S550: Store the grayscale display voltage.

[0164] Step S560: Receive a display instruction and call the grayscale display voltage according to the display instruction.

[0165] Specifically, after obtaining the grayscale display voltages of different display partitions according to the result of the one-time program operation, the grayscale display voltage can also be stored in the register of the driving chip. If a display instruction is received subsequently, the previously stored grayscale display voltage can be directly called from the register, which is convenient for the driving chip to quickly respond to the display instruction, improve the response speed of the display device, and improve the display effect of the display device.

[0166] Step S570: Drive the display partition to display according to the grayscale display voltage of the display partition.
