[0068] Example 1:
[0069] Reference Figure 1 FIG. 1 is a flow chart of a method for adjusting parameters of a mini-led algorithm board according to an embodiment of the present invention. In this embodiment, the method for adjusting parameters of a mini-led algorithm board includes:
[0070] S1. Obtain the input screen and screen display requirements of the target user in the mini-led display screen, wherein the mini-led display screen includes a mini-led algorithm board and an algorithm board adjustment component, and the mini-led algorithm board and the algorithm board adjustment component are connected via serial port communication.
[0071] The embodiment of the present invention can clarify the user's screen display intention by obtaining the input screen and screen display requirements of the target user on the mini-led display screen, such as what style of display he wants on the mini-led display screen (such as partial display, full display and split-screen display, etc.), as well as the display parameters of the screen display, such as overall brightness, local brightness and contrast.
[0072] Among them, the mini-led display screen includes a mini-led algorithm board and an algorithm board adjustment component, and the mini-led algorithm board and the algorithm board adjustment component are connected through serial port communication.
[0073] It should be further explained that the mini-led display screen refers to a display device that uses Mini-LED technology and can process the input picture through a mini-led algorithm board, and finally present the adjusted picture to the user. The mini-led algorithm board refers to a printed circuit board (PCB) that integrates specific algorithms and processing circuits. It uses advanced algorithms to process images and display signals. The algorithm board adjustment component refers to a tool for adjusting the parameters of the mini-led algorithm board, which includes a serial communication interface, a parameter adjustment unit, a status display interface and a data cache interface. The serial communication interface can be used to communicate with the mini-led algorithm board, the parameter adjustment unit can be used to adjust the display parameters of the mini-led algorithm board, the status display interface can be used to display the adjustment parameters of the mini-led algorithm board, and the data cache interface can be used to store data of the adjustment data of the display parameters of the mini-led algorithm board.
[0074] As an embodiment of the present invention, obtaining the input screen and screen display requirements of the target user on the mini-LED display screen includes:
[0075] After wirelessly connecting the Bluetooth device to the data interface corresponding to the mini-LED display screen, the target user's to-be-displayed image is transmitted to the data storage interface corresponding to the mini-LED display screen by using the Bluetooth device to obtain the input image.
[0076] The display menu corresponding to the mini-led display screen is used to obtain the interface display parameters of the target user and obtain the screen display requirements.
[0077] Among them, the display menu refers to a function menu in the mini-LED display screen that can be used for the screen display needs of mobile phone users, such as preset modes such as "standard mode", "cinema mode" and "game mode", as well as screen display styles such as cool colors, warm colors, etc.
[0078] Optionally, the input screen can be obtained by enabling the Bluetooth function on the mini-led display and the Bluetooth device, pairing the two according to the Bluetooth communication protocol, and wirelessly transmitting the screen to be displayed stored in the Bluetooth device to the data storage interface of the display. The screen display requirements can be obtained in the display menu interface of the mini-led display by the user through an operating device such as a remote control or a touch screen, and selecting interface display parameters such as display mode, brightness and contrast.
[0079] S2. Based on the screen display requirements, after determining the screen adjustment properties required for the input screen in the mini-led algorithm board, the algorithm board adjustment component performs data frame format verification on the mini-led algorithm board.
[0080] The embodiment of the present invention determines the picture adjustment properties required for the input picture in the mini-led algorithm board based on the picture display requirements, so as to clarify the processing direction and specific requirements of the algorithm board for the input picture, so that the algorithm board can optimize the picture in a targeted manner to meet the display effect expected by the user.
[0081] As an embodiment of the present invention, determining the screen adjustment properties required for the input screen in the mini-led algorithm board based on the screen display requirements includes:
[0082] Performing parameter mapping on the screen display requirements to obtain requirement parameters;
[0083] Constructing an adjustment mapping relationship between the demand parameters and the mini-led algorithm board;
[0084] Based on the adjustment mapping relationship, the screen display requirements are mapped to the screen adjustment properties required in the mini-led algorithm board.
[0085] Among them, the adjustment mapping relationship refers to a set of corresponding rules and relationships that convert the screen display requirement parameters obtained from the display menu into screen adjustment attribute parameters that the mini-led algorithm board can understand and execute.
[0086] During the specific implementation process, the interface display parameters can be analyzed to separate different parameter values such as brightness, contrast, color saturation and color temperature. For example, if the user sets the brightness parameter to 80, the required parameters of the brightness dimension are clarified (the principles of other parameters are the same). Then, based on the characteristics and display principles of the mini-led algorithm board, the analyzed parameter values are mapped to specific picture adjustment properties. For example, the brightness value corresponds to the parameter in the algorithm board that controls the backlight intensity, the contrast adjustment corresponds to the parameter for enlarging or reducing the difference between different gray levels in the picture, and the color saturation corresponds to the adjustment parameter for color vividness, etc., so as to clarify the adjustment mapping relationship. Finally, the picture adjustment properties are determined based on parameters such as the backlight intensity, the enlargement or reduction parameters for the difference between different gray levels, and the adjustment parameters for color vividness.
[0087] Furthermore, in an embodiment of the present invention, the algorithm board adjustment component performs data frame format verification on the mini-LED algorithm board to ensure that the data input to the algorithm board can be correctly parsed and processed. If the data frame format is incorrect, the algorithm board may not be able to correctly recognize the data, thereby affecting the accuracy of the image adjustment and may even cause system errors or abnormal image display.
[0088] The data frame format refers to the structural form of data organization and encoding during data transmission, such as the frame header, frame trailer, and data field.
[0089] As an embodiment of the present invention, the data frame format verification of the mini-led algorithm board by the algorithm board adjustment component includes:
[0090] Query the serial communication interface in the algorithm board adjustment component;
[0091] Based on the serial communication interface, identify the interface communication protocol corresponding to the mini-led algorithm board;
[0092] Based on the interface communication protocol, query the data frame header, data frame tail and length field of the corresponding received data of the mini-led algorithm board;
[0093] The mini-led algorithm board is subjected to data frame format verification based on the data frame header, data frame tail and length field.
[0094] Among them, the interface communication protocol refers to the data transmission rules that specify the data transmission method (such as serial or parallel), the signal logic level, and the structure and format of the data frame. The data frame header refers to the starting part of the data frame, which is usually composed of a specific byte sequence and is used to identify the beginning of a data frame. The data frame trailer refers to the end of the data frame, which is also composed of a specific byte sequence and is used to mark the end of the data frame. The length field refers to an important component of the data frame and is used to indicate the length of the valid data part in the data frame.
[0095] Optionally, the interface communication protocol may use pattern matching technology or protocol feature recognition algorithm to send a series of preset protocol detection instructions to the queried serial communication interface to determine its corresponding interface communication protocol, such as SPI, I2C, etc. Based on the interface communication protocol, the data frame header, data frame tail and length field may be extracted from the data received by the algorithm board according to the position and format specified by the protocol based on the identified interface communication protocol specification. The data frame format check of the mini-led algorithm board may check whether the extracted data frame header and frame tail comply with the identification specified by the protocol, and whether the length represented by the length field is consistent with the actual received data length.
[0096] S3. When the data frame format verification is successful, the picture adjustment parameters of the input picture in the mini-led algorithm board are configured in the algorithm board adjustment component according to the picture adjustment properties to perform picture adjustment of the input picture, and monitor in real time whether the adjusted input picture meets the picture display requirements.
[0097] It should be explained that the successful data frame format check means that after the data frame is format checked, it is confirmed that the data frame complies with predetermined format standards and specifications.
[0098] Furthermore, the embodiment of the present invention configures the picture adjustment parameters of the input picture in the mini-led algorithm board in the algorithm board adjustment component according to the picture adjustment properties to perform picture adjustment of the input picture. The input picture can be adjusted to the desired display state, so that the picture can be presented to the user with the best effect on the mini-led display screen.
[0099] As an embodiment of the present invention, according to the picture adjustment attribute, configuring the picture adjustment parameters of the input picture in the mini-led algorithm board in the algorithm board adjustment component to perform the picture adjustment of the input picture includes:
[0100] constructing picture adjustment parameters of the input picture based on the picture adjustment attributes;
[0101] The picture adjustment parameters are used to adjust the backlight dark detail enhancement multiple slider, the backlight gamma compensation slider and the driver IC current increment slider in the algorithm board adjustment component to perform picture adjustment of the input picture.
[0102] Among them, the backlight dark detail enhancement multiple slider refers to a tool used to adjust the detail performance of the backlight in the dark area of the Mini-LED display screen, the backlight gamma compensation slider refers to a tool used to perform gamma correction on the backlight of the Mini-LED display screen, and the driver IC current increment slider refers to a tool used to control the current output by the driver IC (Integrated Circuit) in the mini-led display screen.
[0103] Preferably, constructing the picture adjustment parameters of the input picture based on the picture adjustment attributes includes:
[0104] The brightness control value and gamma value of the mini-led algorithm board are obtained from the image adjustment properties. Based on the brightness control value and the gamma value, the brightness adjustment value of the input image is calculated using the following formula:
[0105] ;
[0106] in, Indicates the brightness adjustment value, Indicates the brightness control value of the mini-led algorithm board. Indicates the gamma value;
[0107] The original red channel gain value, the original green channel gain value, and the original blue channel gain value of the input image are obtained from the image adjustment properties. Based on the original red channel gain value, the original green channel gain value, and the original blue channel gain value, the three-channel gain values of the input image are calculated using the following formula:
[0108] ;
[0109] ;
[0110] ;
[0111] in, Indicates the red channel gain value among the three channel gain values. Indicates the green channel gain value among the three channel gain values. Indicates the blue channel gain value among the three channel gain values. The corresponding color saturation adjustment value in the display screen is shown. Indicates the original red channel gain value of the input image, Indicates the original green channel gain value of the input image. Indicates the original blue channel gain value of the input image;
[0112] Extract the original pixel value of the input image from the image adjustment attribute, and calculate the contrast adjustment value of the input image based on the original pixel value using the following formula:
[0113] ;
[0114] in, Indicates the contrast adjustment value, Represents the original pixel value of the input image, Indicates the corresponding contrast adjustment value in the screen display requirements;
[0115] Image adjustment parameters of the input image are constructed based on the brightness adjustment value, the three-channel gain values, and the contrast adjustment value.
[0116] Furthermore, the embodiments of the present invention can timely discover problems that may occur during the picture adjustment process, such as over-adjustment or under-adjustment, by real-time monitoring whether the adjusted input picture meets the picture display requirements, so as to take timely measures to make further adjustments or optimizations.
[0117] As an embodiment of the present invention, the real-time monitoring of whether the adjusted input screen meets the screen display requirement includes:
[0118] collecting optical data corresponding to the adjusted input image in real time;
[0119] converting the optical data into a normalized brightness matrix;
[0120] Performing dynamic partition feature extraction on the standardized brightness matrix to obtain a partition brightness feature set;
[0121] Based on the partition brightness feature set, it is evaluated whether the adjusted input image meets the image display requirement.
[0122] Among them, the optical data refers to the information related to the light signal of the input picture after adjustment, including the light intensity, color (spectral distribution) and other data of each pixel point; the standardized brightness matrix refers to the matrix form obtained by arranging the collected optical data into a matrix form according to pixel coordinates; the partitioned brightness feature set refers to a set of a series of brightness-related features extracted for each partition after dynamically partitioning the standardized brightness matrix, such as average brightness, brightness variance, and brightness gradient.
[0123] Optionally, the optical data can be captured in real time using an electro-diode array at a millisecond sampling frequency to obtain a spectral distribution of the light intensity of each pixel of the adjusted image. The partitioned brightness feature set can be dynamically divided into different regions using a mean clustering method, and then the average brightness, brightness variance, and brightness gradient of each region are calculated. The calculated features are then summarized to obtain the obtained features. Based on the partitioned brightness feature set, the evaluation of whether the adjusted input image meets the image display requirements can be performed by comparing the partitioned brightness feature set with standard parameters such as the brightness threshold and contrast range preset in the image display requirements. Based on the comparison results, the evaluation of whether the image meets the standards is performed. For example, in an application scenario of a mini-LED display, the user sets the image display requirements as follows: the brightness threshold is between 100-500 nits, and the contrast range is 800:1-3000:1. The image is then divided into four regions for analysis: Region 1: The average brightness is 120 nits, the brightness variance is 20 (reflecting small brightness fluctuations), and the calculated contrast is 1000:1; Region 2: The average brightness is 80 nits (lower than the brightness threshold lower limit of 100). nits), a brightness variance of 15, and a contrast ratio of 700:1 (below the lower limit of the contrast range of 800:1); area three: an average brightness of 400 nits, a brightness variance of 30, and a contrast ratio of 2000:1; and area four: an average brightness of 600 nits (above the upper brightness threshold of 500 nits), a brightness variance of 25, and a contrast ratio of 2500:1. These subarea brightness feature sets (including data such as average brightness, brightness variance, and contrast) are input into a pre-trained decision tree model. The decision tree model then determines whether the average brightness is within the threshold range. If the average brightness of area two, 80 nits, is less than 100 nits, the area is directly deemed to fail the standard. Contrast is then assessed: area two's contrast ratio of 700:1 is less than 800:1, also failing the standard. Combining the judgment results for all areas, it is determined that area two does not meet the brightness and contrast requirements, and area four does not meet the brightness requirement. Ultimately, the adjusted input image does not meet the display requirements.
[0124] Furthermore, as another optional embodiment of the present invention, converting the optical data into a standardized brightness matrix includes:
[0125] Performing a brightness calibration conversion operation on the optical data to obtain physical brightness data;
[0126] Normalizing the physical brightness data to obtain standardized brightness data;
[0127] Performing geometric correction on the standardized brightness data to obtain geometric correction data;
[0128] Perform matrix transformation on the geometric correction data to obtain a standardized brightness matrix.
[0129] Among them, the physical brightness data refers to the data obtained by performing a brightness calibration conversion operation on the optical data, which reflects the intensity information of the light in the actual physical scene. The standardized brightness data refers to the data obtained after normalization processing of the physical brightness data. The geometric correction data refers to the data obtained after geometric correction of the standardized brightness data.
[0130] Optionally, the physical brightness data can be obtained by calibrating the optical data using a brightness calibration algorithm, the standardized brightness data can be obtained by mapping the physical brightness data to a fixed numerical range, such as the interval [0, 1], using a normalization algorithm, and the geometric correction data can be obtained by performing geometric data correction on the standardized brightness data using a geometric correction algorithm, such as repositioning and mapping pixel points in the image data to restore the image to the correct geometric shape. The standardized brightness matrix can convert the geometrically corrected data into matrix elements, and use the matrix elements to construct a matrix for the optical data.
[0131] S4. When the adjusted input picture does not meet the picture display requirement, return to the step of configuring the picture adjustment parameters of the input picture in the mini-led algorithm board in the algorithm board adjustment component.
[0132] The embodiment of the present invention returns to the step of configuring the picture adjustment parameters of the input picture in the mini-led algorithm board in the algorithm board adjustment component when the adjusted input picture does not meet the picture display requirements. By continuously adjusting the picture parameters according to the monitoring results, the picture output by the mini-led display screen can be made as close as possible to the display requirements set by the user, ensuring that the picture achieves ideal visual effects in terms of brightness, contrast, color, etc., and providing users with high-quality display pictures.
[0133] It should be explained that the input picture after adjustment not meeting the picture display requirement means that the input picture after adjustment does not meet the preset picture display requirement standards in one or more display indicators such as brightness, contrast, color saturation and clarity.
[0134] Furthermore, as an embodiment of the present invention, after returning to execute the step of configuring the picture adjustment parameters of the input picture in the mini-led algorithm board in the algorithm board adjustment component, it also includes:

[0139] Monitor the screen display requirements of the mini-led algorithm board that displays parameter adjustments again;
[0140] When the result of the screen display demand monitoring meets the preset result, the screen display parameter adjustment of the mini-led algorithm board is completed.
[0141] Among them, the parameter items refer to specific indicators that describe the screen display characteristics that do not meet the screen display requirements, such as brightness, contrast and color saturation. The specific adjustment value refers to the quantitative adjustment amount calculated for the parameter item that does not meet the screen display requirements. The updated display parameter refers to a set of new parameters obtained after updating the original mini-led algorithm board screen display parameters in combination with the specific adjustment value.
[0142] Optionally, the parameter items can compare the various parameters of the adjusted input screen (such as brightness, contrast, color saturation, etc.) obtained through real-time monitoring with the preset screen display requirement parameters one by one to find out the specific items with differences. The specific adjustment value can be obtained by calculating the specific value that needs to be adjusted based on the difference between the current value of the parameter item that does not meet the requirements and the preset value. For example, if the current brightness value is lower than the preset value, the difference between the two is calculated as the brightness adjustment value. The updated display parameters can be obtained by adding the calculated specific adjustment value to the existing corresponding screen display parameters of the mini-led algorithm board.
[0143] When the result of the demand monitoring displayed on the screen meets the preset result, it means that the monitoring result shows that various parameters are within the preset demand range.

[0145] In the embodiment of the present invention, when the adjusted input screen meets the screen display requirement, the adjusted input screen is used as the final display screen, and the screen can be optimized according to the preset display requirements, so that the displayed content meets the user viewing requirements and improves user satisfaction.
