[0045] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the following will be combined with the accompanying drawings for the embodiments of the present disclosure to make a clear and complete description of the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. The components of the embodiments of the present disclosure generally described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed present disclosure, but only 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 work fall within the scope of protection of the present disclosure.

[0046] It should be noted that similar reference numerals and letters refer to similar items throughout the accompanying drawings, and therefore, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0047] The term "and / or" used herein only describes an associated relationship, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the term "at least one" used herein means any one of a plurality or any combination of at least two of a plurality, for example, including at least one of A, B and C can mean including any one or more elements selected from the set consisting of A, B and C.

[0048] It is found through research that, with the market demand for large-size displays, the viewing angle characteristics of the display become an important indicator for evaluating the performance of the display. Generally, the VA (Vertical Alignment) type liquid crystal display picture is prone to color deviation and color washout problems. In order to improve the viewing angle of the VA display, most panel manufacturers use multi-domain pixel design technology to achieve the purpose of viewing angle compensation. However, the more the number of domains of the display is, the more complex the preparation process of the display is, and the higher the manufacturing cost is, which leads to difficulty in practical application.

[0049] Based on the above research, the display panel view angle compensation method, device, computer system and storage medium are provided. In the embodiment of the present disclosure, first, the preset pixel structure can be obtained, and the gray scale arrangement information of the pixel points of the display panel is determined based on the preset pixel structure. Then, the level value of each pixel point in the display panel is adjusted according to the gray scale arrangement information, so that the values of each pixel point in the display panel are not the same, so as to simulate the picture display effect of the display panel with a larger domain number by a smaller domain number, thereby improving the color deviation and white problem of the display panel, reducing the manufacturing cost of the display panel, and making the present disclosure have higher practical application value.

[0050] In order to facilitate the understanding of the present embodiment, first, a display panel view angle compensation method disclosed by the present embodiment is introduced in detail. The execution subject of the display panel view angle compensation method provided by the present embodiment is generally a computer device with certain computing power. In some possible implementation manners, the display panel view angle compensation method can be realized by calling the computer readable instructions stored in the memory by the processor.

[0051] Referring to Figure 1 The flowchart of the display panel view angle compensation method provided by the present embodiment is shown in FIG. 1. The method comprises steps S101-S105, wherein:

[0052] S101: Obtain a preset pixel structure.

[0053] In the present embodiment, first, the target domain number that the display panel needs to achieve can be determined, and the preset pixel structure is determined based on the target domain number. Here, the display panel can be a multi-domain VA type liquid crystal display, for example, an LCD (Liquid Crystal Display). Here, the target domain number is greater than the domain number of the display panel, for example, the domain number of the display panel can be 4 domains, and the target domain number can be 8 domains or 16 domains, etc.

[0054] It should be understood that the domain number of the display panel can be used to indicate the number of liquid crystal molecules in each cluster of liquid crystal molecules in a pixel area. As Figure 2 The arrangement of a cluster of liquid crystal molecules in a pixel area of a 4-domain display panel is shown in FIG. 2. In this cluster of liquid crystal molecules, the azimuth angle of each liquid crystal molecule is different, so that the user can have a better viewing experience in different directions. Compared with the single-domain display panel, the view angle compensation in different azimuth angles is realized. However, the view angle performance of the 4-domain display panel is not satisfactory, and there are still problems of side view color deviation and white deviation.

[0055] Therefore, the present disclosure can reorganize the pixel structure of the 4-domain display panel to improve the domain number of the display panel, for example, to simulate the picture display effect of an 8-domain display. Here, as Figure 3 FIG. 1 shows a schematic diagram of the arrangement of liquid crystal molecules in a pixel region of an 8-domain display panel. Specifically, a pixel region can be divided into a main region and a sub-region, and the tilt angle θ of the liquid crystal molecule clusters in the main region and the sub-region is different (the tilt angle θ is the brightness compensation viewing angle of the pixel region, and the greater the brightness compensation viewing angle, the higher the brightness of the pixel region), wherein the tilt angle of the liquid crystal molecule clusters in the main region is θ1, and the tilt angle of the liquid crystal molecule clusters in the sub-region is θ2. It should be understood that the number of liquid crystal molecule clusters included in each pixel region can be multiple, and the present disclosure does not specifically limit this. Therefore, compared with 4-domain, the 8-domain display panel better realizes the viewing angle compensation in different azimuth angles. The process of reorganizing the pixel structure of the 4-domain display panel is described below, and will not be described here.

[0056] S103: Determine the gray scale arrangement information of the pixel points of the display panel based on the preset pixel structure, wherein the gray scale arrangement information is used to indicate the gray scale value of each pixel point in the display panel.

[0057] In the present disclosure, when the pixel region is at different gray scale values (the gray scale value is used to indicate the brightness of the pixel region, and is usually 0-255), the tilt angle θ of the liquid crystal molecule clusters therein is different, and the higher the gray scale value, the higher the brightness of the pixel region, and the greater the tilt angle θ of the liquid crystal molecule clusters.

[0058] Therefore, in the preset pixel structure, a pixel point in a display panel with a higher domain number can be simulated by combining multiple pixel points. For example, when the target domain number corresponding to the preset pixel structure is 8-domain, two pixel points in a 4-domain display panel, i.e., pixel point 1 and pixel point 2, can be included, the tilt angle of the liquid crystal molecule clusters in the main region of the pixel region corresponding to the pixel point 1 in the 8-domain display panel is θ1, and the tilt angle of the liquid crystal molecule clusters in the sub-region corresponding to the pixel point 2 is θ2.

[0059] When determining the gray scale arrangement information of the pixel points of the display panel based on the preset pixel structure, the gray scale value corresponding to each pixel point in the display panel can be determined first. Specifically, the gray scale values of adjacent pixel points in the display panel can be set, for example, one of the two adjacent pixel points is set to a high gray scale value (H), and the other is set to a low gray scale value (L) to obtain the gray scale arrangement information, thereby realizing the domain increase of the 4-domain display panel to better perform viewing angle compensation. When the target domain number corresponding to the preset pixel structure is 8-domain, the process of specifically determining the gray scale arrangement information of the pixel points of the 4-domain display panel is shown in FIG. 2. Figure 4

[0060] ​S105: Adjust the level value of each pixel point in the display panel according to the gray scale arrangement information.

[0061] In the embodiment of the present disclosure, the level value of the pixel point is used to indicate the voltage value corresponding to the pixel point when the display panel is rendering. Here, different gray scale values correspond to different level values, and the greater the gray scale value of the pixel point, the higher the level value when the pixel point is powered.

[0062] Therefore, after determining the gray scale arrangement information corresponding to the display panel, the level value of each pixel point in the display panel can be adjusted based on the gray scale arrangement information. For example, the level value of the pixel point with a high gray scale value is increased, and the level value of the pixel point with a low gray scale value is decreased.

[0063] As described above, in the embodiment of the present disclosure, the preset pixel structure can be obtained first, and the gray scale arrangement information of the pixel points of the display panel is determined based on the preset pixel structure. Then, the level value of each pixel point in the display panel is adjusted according to the gray scale arrangement information, so that the values of the pixel points in the display panel are not the same, so that a display panel with a larger number of domains can be simulated by a smaller number of domains to display the picture display effect, thereby improving the color deviation and whitening problem of the display panel, reducing the manufacturing cost of the display panel, and making the present disclosure have higher practical application value.

[0064] In an optional implementation, the step S103 of determining the gray scale arrangement information of the pixel points of the display panel based on the preset pixel structure includes the following process:

[0065] S1031: Determine the number of pixel points in the sub-pixel combination based on the preset pixel structure.

[0066] S1032: Determine the gray scale value of each pixel point in the sub-pixel combination respectively to obtain sub-gray scale arrangement information.

[0067] S1033: Arrange the pixel points in the display panel in a loop according to the sub-gray scale arrangement information to obtain the gray scale arrangement information.

[0068] In the embodiment of the present disclosure, a viewing angle compensation algorithm corresponding to a plurality of preset pixel structures can be written in the TCON (Timing Controller) of the display panel. Each preset pixel structure corresponds to a target domain number which is different, for example, 8 domains, 16 domains, etc.

[0069] Specifically, one of the plurality of preset pixel structures can be determined, and the number of pixel points in the sub-pixel combination required by the display panel to achieve the target domain number can be calculated through the viewing angle compensation algorithm. For example, when the domain number of the display panel is 4 domains, if the target domain number corresponding to the preset pixel structure is 8 domains, the number of pixel points in the sub-pixel combination is 2.

[0070] Next, the gray scale values of each pixel point in the sub-pixel combination can be determined based on the arrangement of the liquid crystal molecule clusters of the pixel points in the display panel corresponding to the target domain number. Specifically, the gray scale values corresponding to the tilt angles of the liquid crystal molecule clusters in different sub-regions in the pixel region of the pixel point of the target domain number can be determined to obtain a plurality of gray scale values. The gray scale values of each pixel point in the sub-pixel combination are determined based on the plurality of determined gray scale values, and the sub-pixel points are arranged to obtain sub-gray scale arrangement information.

[0071] After the sub-gray scale arrangement information is determined, the pixel points in the display panel can be arranged in a loop based on the sub-gray scale arrangement information in a certain loop direction, for example, from left to right or from top to bottom, to obtain gray scale arrangement information.

[0072] In the embodiments of the present disclosure, the viewing angle compensation algorithm corresponding to the plurality of preset pixel structures can be written in the TCON of the display panel, so as to control the domain number of the display panel through the compensation algorithm, for example, to simulate the display effect of an 8-domain display panel through a 4-domain display panel. It should be understood that the design of an 8-domain display panel will cause the opening rate to decrease, which will affect the transmittance of the panel and thus limit its application in high-resolution products. However, the present disclosure can simulate an 8-domain display panel through an algorithm, so as to increase the domain number while ensuring the transmittance of the display panel.

[0073] In an optional embodiment, the step S1031 of determining the number of pixel points in the sub-pixel combination based on the preset pixel structure specifically includes the following process:

[0074] (1) determining the sub-domain number of the pixel points in the display panel, wherein the domain number is used to indicate the number of sub-pixel regions in the pixel point;

[0075] (2) determining the total domain number based on the preset pixel structure;

[0076] (3) determining the number of pixel points in the sub-pixel combination based on the ratio of the total domain number to the sub-domain number.

[0077] In the embodiments of the present disclosure, the sub-domain number of the pixel points in the display panel can be determined first, which can be determined based on the number of pixel regions included in the pixel region of the pixel point, i.e., the sub-pixel region.

[0078] After the number of sub-domains is determined, the total number of domains, i.e., the target number of domains, can be determined based on the preset pixel structure. Then, a ratio of the total number of domains to the number of sub-domains can be calculated, and the ratio is determined as the number of pixel points in the sub-pixel combination. For example, when the number of sub-domains of a middle pixel point of the display panel is 8 domains, and the total number of domains corresponding to the preset pixel structure is 16 domains, the ratio of the two is 2, and the number of pixel points in the sub-pixel combination is 2.

[0079] In the embodiments of the present disclosure, the viewing angle compensation algorithm corresponding to a plurality of preset pixel structures can be written in the TCON of the display panel, so as to adapt to different use scenarios, to control the number of domains of the display panel through the compensation algorithm, to adapt to different use environments, to dynamically adjust the number of domains of the display panel, and to improve the user's viewing experience.

[0080] In an optional implementation, the preset pixel structure includes a first high gray scale value, a second high gray scale value, a first low gray scale value, and a second low gray scale value. The step S1032 of determining the gray scale values of each pixel point in the sub-pixel combination to obtain the sub-gray scale arrangement information includes the following processes.

[0081] (1) Determine the number of pixel points corresponding to each gray scale value in the preset pixel structure in the sub-pixel combination.

[0082] (2) Determine the arrangement order information of each gray scale value indicated by the preset pixel structure.

[0083] (3) Determine the gray scale values of each pixel point in the sub-pixel combination according to the arrangement order information and the number of pixel points, to obtain the sub-gray scale arrangement information.

[0084] In the embodiments of the present disclosure, the target number of domains corresponding to the preset pixel structure can include 8 domains or 16 domains. When the target number of domains is 8 domains, the preset pixel structure can include a high gray scale value and a low gray scale value. When the gray scale arrangement information is determined based on the preset pixel structure of 8 domains, as shown in FIG. 8, the gray scale arrangement information includes a high gray scale value and a low gray scale value. Figure 5 FIG. 8 shows a gamma curve comparison diagram when the display panel operates based on the gray scale arrangement information.

[0085] FIG. 9 shows a gamma curve comparison diagram when the display panel operates based on the gray scale arrangement information. Figure 5In the coordinate system shown, the horizontal axis represents the gray level value, and the vertical axis represents the brightness value. Curve 1 is the on-axis gamma curve of the display panel when running without the compensation algorithm. Curve 2 is the off-axis gamma curve of the display panel when running without the compensation algorithm. Curve 3 is the off-axis gamma curve of the display panel when running with the compensation algorithm, based on the gray level arrangement information corresponding to the preset pixel structure of 8 domains.

[0086] Depend on Figure 5 As can be seen, after adopting the compensation algorithm, the gamma curve of the side view is significantly closer to that of the front view. In other words, the brightness difference between the side view and the front view is significantly reduced, which saves processor computing power as much as possible while ensuring the user's viewing experience.

[0087] However, in situations where a higher level of viewing experience is required, the viewing angle compensation algorithm can adaptively adopt a preset pixel structure with a target number of 16 domains based on the usage conditions, and determine the grayscale arrangement information based on this preset pixel structure with 16 domains. Here, as... Figure 5 As shown, curve 4 is the gamma curve from the side view when the display panel operates based on the grayscale arrangement information corresponding to the preset pixel structure of 16 domains after the compensation algorithm is applied.

[0088] As can be seen from curve 4 above, after adopting the compensation algorithm, the gamma curve of the side view is closer to the front view than curve 3. In other words, the brightness difference between the side view and the front view is further reduced, which further improves the user's viewing experience.

[0089] Based on this, in this embodiment of the disclosure, the target domain number corresponding to the preset pixel structure can be 16 domains, thereby improving the user's viewing experience. Specifically, the preset pixel structure may include a first high grayscale value (H1), a second high grayscale value (H2), a first low grayscale value (L1), and a second low grayscale value (L1), wherein H1 > H2 > L2 > L1.

[0090] Next, the number of pixels corresponding to the sub-pixel set can be determined, and corresponding pixels can be assigned to each grayscale value based on this number. Here, the number of pixels assigned to each grayscale value can be the same or different. For example, the number of pixels corresponding to the sub-pixel set can be 4, with each grayscale value corresponding to a different pixel.

[0091] Then, arrangement order information of the gray scale values can be determined based on the preset pixel structure, and the gray scale values of the pixel points in the sub-pixel combination can be determined according to the arrangement order information and the number of the pixel points in the sub-pixel combination, to obtain sub-gray scale arrangement information. For example, the arrangement order information can be that the gray scale values of the pixel points are sequentially decreased in the arrangement direction, that is, from left to right and from top to bottom, and the gray scale values of the pixel points are H1, H2, L2 and L1 in sequence.

[0092] In addition, as shown in FIG. 16, the gray scale arrangement information is determined based on the preset pixel structure of 16 domains. Figure 6 The specific determination process refers to the process of determining the gray scale arrangement information based on the preset pixel structure of 8 domains, which will not be described here.

[0093] In the embodiment of the present disclosure, the preset pixel structure with a target domain number of 16 domains can be adopted, and the sub-gray scale arrangement information is obtained based on the gray scale values of the pixel points in the sub-pixel combination of the preset pixel structure of 16 domains, which provides a technical basis for determining the gray scale arrangement information in the next step, so that the difference between the brightness at the side viewing angle and the brightness at the normal viewing angle is small when the display panel displays the picture based on the gray scale arrangement information, and the user's viewing experience is improved.

[0094] In an optional implementation, the step S103 further includes the following process:

[0095] (1) After obtaining the sub-gray scale arrangement information, the sum of the original gamma values of the pixel points in the sub-pixel combination is determined.

[0096] (2) The target gamma value corresponding to each of the pixel points in the sub-pixel combination is determined based on the gray scale values of the pixel points, and the sum of the target gamma values is calculated.

[0097] (3) In the case where the sum of the original gamma values is not equal to the sum of the target gamma values, the gray scale values of the pixel points in the sub-pixel combination are adjusted.

[0098] In the embodiment of the present disclosure, in order to ensure the picture display effect of the display panel adjusted based on the viewing angle compensation algorithm, it is necessary to make the brightness of the adjusted display panel consistent with that before the adjustment. Specifically, the sum of the gamma values of the pixel points in the display panel can be made the same as that before the adjustment.

[0099] In a specific implementation, the first high gray scale value (H1), the second high gray scale value (H2), the first low gray scale value (L1), and the second low gray scale value (L1) are taken as examples in the preset pixel structure. After the sub-gray scale arrangement information is obtained, the sum of the original gamma values of the pixel points in the sub-pixel combination can be determined. Here, the original gamma value is Gamma2.2, and the sum of the original gamma values is 4*Gamma2.2. The sum of the target gamma values is Gamma_H1+Gamma_L1+Gamma_H2+Gamma_L2.

[0100] To ensure the picture display effect of the display panel adjusted based on the viewing angle compensation algorithm, it can be determined whether Gamma_H1+Gamma_L1+Gamma_H2+Gamma_L2=4*Gamma2.2 is established. If yes, the viewing angle compensation algorithm is executed. If no, the gray scale values of the pixel points in the sub-pixel combination are adjusted to make the equation established.

[0101] In the embodiments of the present disclosure, the sum of the gamma values of the pixel points in the display panel can be made the same as before the adjustment, so that the brightness of the display panel adjusted based on the viewing angle compensation algorithm remains the same as before the adjustment, and the picture display effect of the display panel is ensured to be good.

[0102] In an optional implementation, the step S105 includes the following process:

[0103] (1) Based on the gray scale arrangement information, the level order of each pixel point in the display panel is determined, where the level value ranges corresponding to different level orders are different.

[0104] (2) The rendering data of the frame to be displayed is obtained, and based on the rendering data and the level order of each pixel point in the display panel, the target level value corresponding to each pixel point is determined.

[0105] (3) Based on the target level value, the level value of each pixel point in the display panel is adjusted.

[0106] In the embodiments of the present disclosure, the mapping relationship between the gray scale value and the level order can be established in advance to obtain mapping information. After the gray scale arrangement information is determined, the level order of each pixel point in the display panel can be found based on the mapping information.

[0107] Next, rendering data of the frame to be displayed can be acquired, and based on the rendering data and the level order of each pixel point, a target level value corresponding to each pixel point can be determined. Then, the TCON can be instructed to adjust the level value of each pixel point in the display panel based on the target level value.

[0108] In the embodiments of the present disclosure, a mapping relationship between the gray scale value and the level order can be established in advance to obtain mapping information, so as to directly find the level order of each pixel point in the display panel based on the mapping information, thereby saving the calculation resources and improving the device response speed.

[0109] To sum up, in the embodiments of the present disclosure, first, a preset pixel structure can be acquired, and the gray scale arrangement information of the pixel points of the display panel is determined based on the preset pixel structure, and then the level value of each pixel point in the display panel is adjusted according to the gray scale arrangement information, so that the values of each pixel point in the display panel are not the same, so as to simulate the display panel with a larger domain number by a smaller domain number, thereby improving the color deviation and white problem of the display panel while reducing the manufacturing cost of the display panel, so that the present disclosure has high practical application value.
