[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] It can be understood that in the field of LCD display technology using mini-LED as a backlight source, in the process of displaying an image, a bright and changing backlight is usually provided for the image according to a pre-designed partitioning situation.

[0056] For example, for an image to be displayed, such as an image displayed on a vehicle's center console or an advertising screen, mini-LED can be used as a backlight source to provide a reasonable backlight source according to the pre-designed partitioning.

[0057] In actual processes, in order to meet the display requirements of images to be displayed in different scenarios, engineers often design mini-LED backlight partitions according to different images to be displayed, so as to match different images to be displayed and present the best display effect.

[0058] For example, for the display scene of the vehicle center console or the display scene of the advertising screen, the bright images to be displayed are different, and different mini-LED backlight partition designs can be used accordingly.

[0059] That is, in the actual process, engineers will carry out mini-LED backlight partition design based on the images to be displayed in different scenarios and personal experience to complete the proofing of the display device.

[0060] Obviously, in the above method, engineers set and proofed the mini-LED backlight partitions without any simulation effects, which resulted in failure to meet customer requirements when actually displaying the image to be displayed, such as the rigid pictures provided by users. This led to repeated design and proofing, which brought about great instability and low efficiency.

[0061] In the present invention, for the image to be displayed in a specific scene, in order to avoid repeated design and proofing by engineers, a mini-LED backlight partition simulation method is provided, so that the partition of the mini-LED can be pre-judged according to the simulation effect, and then the partition design can be flexibly adjusted according to the simulation result, providing a reasonable basis for the actual partition design, and finally achieving accurate and reasonable partition design to ensure display quality.

[0062] It can be understood that the simulation software that implements this method can run on a computer device, so that the user can start the design program and set parameters on the operating interface of the simulation software to realize the image to be displayed, presenting different display effects under different partition designs.

[0063] In order to better understand the mini-LED partition simulation design method provided by the present invention, it is described in detail below with reference to the accompanying drawings.

[0064] Figure 1 FIG. 1 is a flow chart of a mini-LED partition simulation design method in some embodiments of the present invention, and the method specifically includes:

[0065] S110, obtaining an image to be displayed and simulation parameters, the simulation parameters including partition parameters and grayscale parameters, the partition parameters representing the area division of the mini-LED backlight, and the grayscale parameters representing the brightness setting of the mini-LED backlight.

[0066] S120, determining the sub-channel grayscale value of each pixel of the image to be displayed according to the set mapping relationship and the grayscale parameter.

[0067] S130, generating a grayscale image of the image to be displayed according to the partition parameter and the sub-channel grayscale value of each pixel point, wherein the grayscale image represents a display result of the image to be displayed based on the simulation parameter.

[0068] Specifically, after the operator starts the designed simulation software and displays an operation interface, such as a configuration interface, on the computer device, the operator can input simulation parameters on the configuration interface so that the computer device can obtain parameters for mini-LED partitioning.

[0069] That is, the simulation parameters may include partition parameters and grayscale parameters of the mini-LED partitions.

[0070] Among them, the partitioning parameters can specifically include the number of rows and columns, which means the degree of fineness of the division of the simulated mini-LED backlight area.

[0071] This grayscale parameter indicates the degree of refinement of the brightness of the simulated mini-LED backlight.

[0072] For example, Figure 3 , Figure 5 and Figure 7 In the configuration interface shown, simulation parameters can be input, that is, the number of rows, the number of columns and grayscale parameters of the simulation can be input.

[0073] In addition, you can also import images to be displayed on the configuration interface, such as 24-bit (8, 8, 8) RGB bitmap BMP.

[0074] That is, in the simulation process of the present invention, the input algorithm variables are simulation parameters, which may specifically be the number of partition columns, the number of partition rows, and the grayscale value.

[0075] For example, Figure 3 , Figure 5 and Figure 7 In the configuration interface shown, you can enter the following parameters:

[0076] BMP: 24-bit (8, 8, 8) RGB bitmap;

[0077] zone_w: number of mini-LED partition columns;

[0078] zone_h: number of mini-LED partition rows;

[0079] grey_level_in:mini-LED gray level grey_in.

[0080] Furthermore, after the computer device obtains the image to be displayed and the simulation parameters, it can determine the sub-channel grayscale value of each pixel of the image to be displayed according to the set mapping relationship and grayscale parameters, and then generate a grayscale map of the image to be displayed according to the partition parameters and the sub-channel grayscale value of each pixel, that is, according to the configured simulation parameters, complete the simulation display of the image to be displayed to represent the display result of the image to be displayed based on the simulation parameters.

[0081] Understandably, in order to avoid infringing personal privacy, Figure 7 The face image in is occluded, that is, Figure 7 The circular occlusion area of ​​the face part is only for the purpose of protecting personal privacy and does not involve the image processing of this application. In actual processing, the original image is still used as the processing object.

[0082] For example, Figure 4 , Figure 6 and Figure 8 As shown, the computing device uses the simulation parameters as the partition result of the mini-LED backlight, and then simulates the display result of the image to be displayed based on the partition result.

[0083] Obviously, the clarity of the simulation results varies with the input simulation parameters.

[0084] It can be understood that the mini-LED partition simulation method provided in the embodiment of the present invention, through the developed simulation software, enables the device to obtain the input image to be displayed and the simulation parameters including the partition parameters and the grayscale parameters when the simulation software is run on the computing device, so that the partition parameters are used as the basis for the regional division of the mini-LED backlight, and the grayscale parameters are used as the brightness division of the mini-LED backlight, and then the sub-channel grayscale value of each pixel of the displayed image is determined according to the set mapping relationship and the grayscale parameters; finally, the grayscale map of the image to be displayed is generated according to the partition parameters and the sub-channel grayscale value of each pixel, and the current simulation is obtained. The simulation results under the partitioning conditions corresponding to the parameters enable the simulation results to be used as the display effect of the image to be displayed after the mini-LED backlight is partitioned according to the current simulation parameters, that is, as a prediction of the mini-LED backlight after partitioning according to the current simulation parameters, thereby providing a reliable and reasonable basis for the actual partitioning design of the mini-LED backlight, so that in the actual design and proofing process of the mini-LED backlight, engineers can simulate the partitioning of the mini-LED backplane by adjusting the simulation parameters, so as to quickly determine the optimal partitioning, avoid repeated design and proofing, improve process efficiency, and reduce design costs.

[0085] Optionally, in some embodiments of the present invention, in S110, when obtaining the simulation parameters, the simulation parameters input through the configuration interface may be obtained.

[0086] The configuration interface may include a partition row number edit box, a partition column number edit box, and a grayscale parameter edit box.

[0087] That is, in the configuration interface, you can enter the number of rows and columns in the partition row number edit box, and enter the grayscale parameters in the grayscale parameter edit box.

[0088] For example, Figure 3 As shown, you can enter 32 rows and 12 columns in the partition row number edit box, and enter 256 grayscale parameters in the grayscale parameter edit box.

[0089] It can be understood that the specific setting method of the configuration interface can be adjusted according to actual conditions, and the present invention does not limit this.

[0090] Optionally, in some embodiments of the present invention, in S120, when determining the sub-channel grayscale value of each pixel point of the image to be displayed according to the set mapping relationship and grayscale parameter, as follows: Figure 2 As shown, it is implemented through the following steps:

[0091] S121, determining the grayscale interval value of each sub-channel corresponding to the grayscale parameter according to the set mapping relationship and the grayscale parameter.

[0092] S122, determining a sub-channel grayscale value of each pixel of the image to be displayed according to the pixel value of each pixel of the image to be displayed and the grayscale interval value.

[0093] Specifically, after obtaining the grayscale parameter, the computer device can determine the sub-channel grayscale interval value corresponding to the grayscale parameter according to the configured mapping relationship, and then determine the sub-channel grayscale value of each pixel of the image to be displayed according to the pixel value of each pixel of the image to be displayed and the grayscale interval value.

[0094] For example, if the input grayscale parameter grey_level_in=256, the grayscale interval value of the grayscale parameter 256, that is, grey_interval, can be determined from the configured mapping relationship: 0, 32, 64, 96, 128, 160, 192, 224.

[0095] For the input image to be displayed, if the pixel value of a certain pixel is COLOR=(Ri, Gi, Bi)=(41, 121, 83).

[0096] Then, the grayscale interval value grey_interval determined above is used to obtain the grayscale values ​​of each sub-channel corresponding to the pixel point, that is, the sub-channel grayscale values ​​of the R, G, and B channels are respectively:

[0097] Rg=32(32<41=Ri<64)

[0098] Gg=96(96<121=Gi<128)

[0099] Bg=64(64<83=Bi<96)

[0100] It can be understood that through the above steps, the sub-channel grayscale value of each pixel point can be determined in sequence, which is used to determine the sub-region grayscale value in each sub-region corresponding to the image to be displayed.

[0101] Optionally, in some embodiments of the present invention, the mapping relationship in S121 may specifically include a first mapping relationship, a second mapping relationship, a third mapping relationship, a fourth mapping relationship, and a fifth mapping relationship.

[0102] The first mapping relationship represents the corresponding relationship between the grayscale parameter value and the grayscale power, which can be specifically expressed by the following formula:

[0103] grey_level_in=2 grey _ in .

[0104] For example, the input grayscale values ​​and grayscale powers can be specifically expressed as follows according to the first mapping relationship:

[0105]

[0106] The second mapping relationship represents the corresponding relationship between the grayscale power and the number of sub-channel grayscale bits, and is used to convert the obtained grayscale power into the corresponding number of sub-channel grayscale bits.

[0107] The second mapping relationship can be expressed as follows: grey_in-n-bit.

[0108] For example, for each grayscale power obtained, the corresponding relationship between it and the number of grayscale bits of the sub-channel can be:

[0109]

[0110] The third mapping relationship represents the corresponding relationship between the number of sub-channel grayscale bits and the channel grayscale increment. It can be expressed by the following formula:

[0111] rgb_channel_grey_increment=2 (8-n-bit) .

[0112] For example, the corresponding relationship between the specific sub-channel grayscale bit conversion and the channel grayscale increment can be expressed as follows:

[0113]

[0114] The fourth mapping relationship represents the corresponding relationship between the grayscale increment of each sub-channel and the number of sub-channel grayscales.

[0115] It can be specifically expressed by the following formula:

[0116] rgb_channel_grey_number=256 / rgb_channel_grey_increment.

[0117] For example, for the above example, the mapping relationship can be expressed as follows:

[0118]

[0119] The fifth mapping relationship represents the corresponding relationship between the number of grayscales of the RGB sub-channels of the picture and the grayscale interval column of the RGB sub-channels of the picture, that is, rgb_channel_grey_increment→rgb_channel_grey_interval.

[0120] For example, for the above example, the fifth mapping relationship can be expressed as:

[0121]

[0122] Correspondingly, based on the above mapping relationships, in S121, the following steps may be specifically included:

[0123] S01, determining a grayscale power corresponding to the grayscale parameter according to the first mapping relationship;

[0124] S02, determining the number of sub-channel grayscale bits corresponding to the grayscale power according to the second mapping relationship;

[0125] S03, determining the sub-channel grayscale increment corresponding to the sub-channel grayscale bit number according to the third mapping relationship;

[0126] S04, determining the number of sub-channel grayscales corresponding to the sub-channel grayscale increment according to the fourth mapping relationship;

[0127] S05 , determining the sub-channel grayscale interval value corresponding to the sub-channel grayscale number according to the fifth mapping relationship.

[0128] Specifically, after the computer device obtains the grayscale parameter, it can first convert the grayscale parameter into a corresponding grayscale power according to a pre-configured variable mapping relationship, that is, a first mapping relationship.

[0129] Furthermore, the computer device converts the grayscale parameter into grayscale power according to the first mapping relationship, and then converts the obtained grayscale power into the corresponding sub-channel grayscale bit number according to the second mapping relationship, that is, the correspondence between the grayscale parameter and the sub-channel grayscale bit number.

[0130] Furthermore, after obtaining the corresponding sub-channel grayscale bit number, the computer device may convert the sub-channel grayscale bit number into a sub-channel grayscale increment according to the third mapping relationship.

[0131] It can be understood that, through the corresponding conversion of the above mapping relationships, the grayscale parameters of the analog parameter input can be converted into the grayscale increments of each sub-channel.

[0132] Furthermore, after the grayscale increment of each sub-channel is obtained, the grayscale increment of each sub-channel may be converted into a corresponding sub-channel grayscale number according to a fourth mapping relationship.

[0133] Furthermore, in some embodiments of the present invention, after the input grayscale parameters are processed and converted in the above steps to obtain the corresponding grayscale number of each sub-channel, the grayscale number of each sub-channel can be converted into the corresponding RGB sub-channel grayscale interval column according to the fifth mapping relationship.

[0134] It can be understood that the parameters corresponding to the conversion of the above mapping relationships are intermediate variables in the execution of the simulation algorithm, including the number of grayscale bits (n-bit, n=1, 2, 3, 4, 5, 6, 7, 8) of the RGB sub-channel of the image.

[0135] rgb_channel_grey_increment: output image RGB subchannel grayscale increment;

[0136] rgb_channel_grey_number: the number of grayscale levels of the RGB subchannels of the output image;

[0137] rgb_channel_grey_interval: output image RGB sub-channel grayscale interval column;

[0138] Rg: output image R subchannel grayscale value;

[0139] Gg: output image G subchannel grayscale value;

[0140] Bg: output image B subchannel grayscale value;

[0141] Ri: grayscale value of R subchannel of input image;

[0142] Gi: grayscale value of G subchannel of input image;

[0143] Bi: grayscale value of subchannel B of input image;

[0144] grey_level_out: output image grayscale;

[0145] zone_grey_level_out: Zone output image grayscale.

[0146] It can also be understood that during the execution of the simulation algorithm, the grayscale interval values ​​of each sub-channel corresponding to the input grayscale parameter can be finally determined through the conversion of the above-mentioned intermediate variables.

[0147] Optionally, in S130, when generating a grayscale image of an image to be displayed according to the configured partition parameters and the grayscale value of each pixel sub-channel, the following steps may be specifically included:

[0148] S131, determining a partition grayscale map of the image to be displayed corresponding to each partition of the mini-LED backlight according to the sub-channel grayscale value of each pixel point of the image to be displayed and the partition parameter;

[0149] S132, splicing the grayscale images of the partitions to obtain a grayscale image of the image to be displayed.

[0150] Specifically, in some embodiments of the present invention, after obtaining the sub-channel grayscale value of each sub-pixel point of the image to be displayed, the partition grayscale map of the image to be displayed corresponding to each partition after division according to the partition parameters can be determined based on the configured partition parameters and the sub-channel grayscale value.

[0151] For example, in some embodiments, the S131 may specifically include the following steps:

[0152] S06, summing up the image pixel grayscale values ​​of each pixel in each partition according to the partition size and the grayscale value of the pixel, to obtain the sum of the grayscale values ​​of the pixels in each partition.

[0153] S07, determining the quotient of the sum value corresponding to each partition and the partition area as the partition grayscale value corresponding to each partition of the image to be displayed.

[0154] S08: Based on the partition grayscale value, output a corresponding partition grayscale image.

[0155] Specifically, finally, after the above-mentioned sub-channel grayscale intervals are obtained, the lower limit value of each sub-channel grayscale value can be determined according to the obtained sub-channel grayscale intervals.

[0156] It can be understood that Rg=R channel grey-interval column contains the lower limit of Ri interval, Gg=G channel grey-interval column contains the lower limit of Gi interval, and Bg=B channel grey-interval column contains the lower limit of Bi interval.

[0157] For example, the input simulation parameter grey_level_in=256. Then, from the above-mentioned 'variable mapping table' 2.4, the grey_interval interval of gray level 256 is obtained as follows: 0, 32, 64, 96, 128, 160, 192, 224.

[0158] Furthermore, in some embodiments of the present invention, through the above steps, the lower limit value corresponding to each pixel point is determined by the configured mapping relationships and the pixel value of each pixel point of the image to be displayed.

[0159] For example, suppose the pixel value of a certain pixel point is COLOR=(Ri, Gi, Bi)=(41, 121, 83).

[0160] Then the above mapping relationship grey_interval is:

[0161] Rg=32(32<41=Ri<64)

[0162] Gg=96(96<121=Gi<128)

[0163] Bg=64 (64<83=Bi<96).

[0164] Finally, the lower limit values ​​of each pixel are averaged to obtain the corresponding grayscale value.

[0165] That is, gray_level_out=(Gg+Gg+Bg) / 3.

[0166] Finally, after obtaining the grayscale value of each pixel point, the sub-pixel grayscale of each pixel in the partition can be accumulated to obtain the accumulated grayscale, and then the accumulated grayscale can be divided by the corresponding partition area to obtain the partition grayscale.

[0167] For example, the sub-pixel grayscale of each pixel is represented by grey_level_out(i, j), where i and j are the positions of the pixel.

[0168] The corresponding code is:

[0169]

[0170] Furthermore, after obtaining the grayscale images of each partition corresponding to the image to be displayed, the grayscale images of each partition can be summed to obtain the grayscale image corresponding to the image to be displayed, that is, to obtain the simulation result corresponding to the image to be displayed under the currently input simulation parameter scenario, which represents the display result of the image to be displayed under the partition design situation corresponding to the simulation parameters.
