[0020] Embodiment 1: Refer to Figure 1 As shown, it is a schematic flowchart of a method for adjusting the parameters of a mini-led algorithm board provided by an embodiment of the present invention. In this embodiment, the method for adjusting the parameters of a mini-led algorithm board includes: S1. Obtain the input picture and the picture display requirements of the target user in the mini-led display screen. 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 communication.

[0021] Through the step of obtaining the input picture and the picture display requirements of the target user in the mini-led display screen in the embodiments of the present invention, the user's picture display intention can be clarified, such as what style to display in the mini-led display screen (e.g., partial display, full display, split-screen display, etc.), and the display parameters of the picture display, such as overall brightness, local brightness, and contrast, etc.

[0022] 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 communication.

[0023] It should be further noted that the mini-LED display screen refers to a display device using Mini-LED technology. It 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) integrated with 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, including 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 establish a communication link 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 adjusted parameters of the mini-LED algorithm board. The data cache interface can be used to store the adjustment data of the display parameters of the mini-LED algorithm board.

[0024] As an embodiment of the present invention, obtaining the input picture and the picture display requirements of the target user in the mini-LED display screen includes: After wirelessly connecting to the corresponding data interface of the mini-LED display screen using a Bluetooth device, the picture to be displayed by the target user is transmitted to the corresponding data storage interface of the mini-LED display screen using the Bluetooth device, and then the input picture is obtained. The interface display parameters of the target user are obtained using the display menu corresponding to the mini-LED display screen, and the picture display requirements are obtained.

[0025] Among them, the display menu refers to a function menu in the mini-LED display screen, which can be used for the picture display requirements of mobile phone users, such as preset modes like "standard mode", "theater mode", and "game mode", as well as display styles of pictures such as cold color tone and warm color tone.

[0026] Optionally, the input picture can be obtained by enabling the Bluetooth function on the mini-LED display screen and the Bluetooth device, pairing and connecting the two according to the Bluetooth communication protocol, and wirelessly transmitting the picture to be displayed stored in the Bluetooth device to the data storage interface of the display screen. The picture display requirements can be obtained by the user selecting interface display parameters such as display mode, brightness, and contrast through operating devices such as a remote control and a touch screen on the display menu interface of the mini-LED display screen.

[0027] S2. After determining the picture adjustment attributes required for the input picture in the mini-LED algorithm board based on the picture display requirements, the algorithm board adjustment component is used to perform data frame format verification on the mini-LED algorithm board.

[0028] In the embodiment of the present invention, by determining the required picture adjustment attributes of the input picture in the mini-led algorithm board based on the picture display requirements, the processing direction and specific requirements of the algorithm board for the input picture can be clarified, enabling the algorithm board to optimize the picture targeted to meet the desired display effect of the user.

[0029] As an embodiment of the present invention, the determining the required picture adjustment attributes of the input picture in the mini-led algorithm board based on the picture display requirements includes: Performing parameter mapping on the picture display requirements to obtain required parameters; Constructing an adjustment mapping relationship between the required parameters and the mini-led algorithm board; Based on the adjustment mapping relationship, mapping the picture display requirements to the required picture adjustment attributes in the mini-led algorithm board.

[0030] Wherein, the adjustment mapping relationship refers to a set of corresponding rules and relationships that convert the picture display requirement parameters obtained from the display menu into picture adjustment attribute parameters that the mini-led algorithm board can understand and execute.

[0031] In the specific implementation process, the interface display parameters can be parsed 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 parameter in the dimension of brightness is clarified (the principle of other parameters is the same). Then, according to the characteristics and display principle of the mini-led algorithm board, the parsed parameter values are mapped to specific picture adjustment attributes. For example, the brightness value corresponds to the parameter controlling the light emission intensity of the backlight in the algorithm board, the contrast adjustment corresponds to the parameter for amplifying or reducing the difference between different gray levels in the picture, and the color saturation corresponds to the parameter for adjusting the vividness of colors, etc., to clarify the adjustment mapping relationship. Finally, the picture adjustment attributes are determined according to the parameters such as the light emission intensity of the backlight, the parameter for amplifying or reducing the difference between different gray levels, and the parameter for adjusting the vividness of colors.

[0032] Furthermore, in the embodiment of the present invention, by performing data frame format verification on the mini-led algorithm board through the algorithm board adjustment component, it can be ensured that the data input into the algorithm board can be correctly parsed and processed. If the data frame format is incorrect, it may cause the algorithm board to fail to correctly identify the data, thereby affecting the accuracy of picture adjustment and even potentially causing system errors or abnormal picture display.

[0033] Wherein, the data frame format refers to the structural form of data organization and encoding during data transmission, such as frame header, frame tail, and data fields.

[0034] 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: Query the serial communication interface in the algorithm board adjustment component; Based on the serial communication interface, identify the interface communication protocol corresponding to the mini-led algorithm board; Based on the interface communication protocol, query the data frame header, data frame tail and length field of the data received by the mini-led algorithm board; Perform data frame format verification on the mini-led algorithm board based on the data frame header, data frame tail and length field.

[0035] Among them, the interface communication protocol refers to the data transmission rules that stipulate the data transmission method (such as serial or parallel), the logic level of the signal, and the structure and format of the data frame. The data frame header refers to the starting part of the data frame, usually composed of a specific byte sequence, which is used to identify the start of a data frame. The data frame tail refers to the end of the data frame, also composed of a specific byte sequence, which is used to mark the end of the data frame. The length field refers to an important part of the data frame, which is used to represent the length of the valid data part in the data frame.

[0036] Optionally, the interface communication protocol can 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 can be extracted from the data received by the algorithm board according to the position and format specified by the recognized interface communication protocol specification. The data frame format verification of the mini-led algorithm board can check whether the extracted data frame header and frame tail conform to the identification specified by the protocol, and whether the length represented by the length field is consistent with the actual received data length.

[0037] S3. When the data frame format verification is successful, configure 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 attributes, so as to perform the picture adjustment of the input picture, and monitor in real time whether the adjusted input picture meets the picture display requirements.

[0038] It should be explained that "when the data frame format verification is successful" means that after checking the format of the data frame, it is confirmed that the data frame conforms to the predetermined format standards and specifications.

[0039] Further, in the embodiment of the present invention, by adjusting the attributes according to the screen, the screen adjustment parameters of the input screen in the mini-led algorithm board are configured in the algorithm board adjustment component to perform the screen adjustment of the input screen, so that the input screen can be adjusted to the desired display state, and the screen can be presented to the user with the best effect on the mini-led display screen.

[0040] As an embodiment of the present invention, the adjusting the attributes according to the screen, configuring the screen adjustment parameters of the input screen in the mini-led algorithm board in the algorithm board adjustment component to perform the screen adjustment of the input screen includes: Constructing the screen adjustment parameters of the input screen based on the screen adjustment attributes; Using the screen adjustment parameters to perform slider adjustment on the backlight dark part detail enhancement multiple slider, the backlight gamma compensation slider, and the driving IC current increment slider in the algorithm board adjustment component to perform the screen adjustment of the input screen.

[0041] Among them, the backlight dark part detail enhancement multiple slider is a tool for adjusting the detail performance degree of the backlight of the Mini-LED display screen in the dark part area, the backlight gamma compensation slider is a tool for performing gamma correction on the backlight of the Mini-LED display screen, and the driving IC current increment slider is a tool for controlling the current magnitude output by the driving IC (Integrated Circuit) in the mini-led display screen.

[0042] Preferably, the constructing the screen adjustment parameters of the input screen based on the screen adjustment attributes includes: Obtaining the brightness control value and the gamma value of the mini-led algorithm board from the screen adjustment attributes, and calculating the brightness adjustment value of the input screen based on the brightness control value and the gamma value by using the following formula: ; Wherein, represents the brightness adjustment value, represents the brightness control value of the mini-led algorithm board, represents the gamma value; Obtaining the original red channel gain value, the original green channel gain value, and the original blue channel gain value of the input screen from the screen adjustment attributes, and calculating the three-channel gain value of the input screen based on the original red channel gain value, the original green channel gain value, and the original blue channel gain value by using the following formula: ; ; ; Wherein, represents the red channel gain value in the three-channel gain value, represents the green channel gain value in the three-channel gain value, represents the blue channel gain value in the three-channel gain value, represents the corresponding color saturation adjustment value in the screen display requirement, represents the original red channel gain value of the input screen, represents the original green channel gain value of the input screen, represents the original blue channel gain value of the input screen; Extract the original pixel value of the input screen from the screen adjustment attributes, and based on the original pixel value, calculate the contrast adjustment value of the input screen using the following formula: ; Wherein, represents the contrast adjustment value, represents the original pixel value of the input screen, represents the corresponding contrast adjustment value in the screen display requirement; Based on the brightness adjustment value, the three-channel gain value, and the contrast adjustment value, construct the screen adjustment parameters of the input screen.

[0043] Furthermore, the embodiment of the present invention can timely discover possible problems in the screen adjustment process, such as over-adjustment or under-adjustment, by real-time monitoring whether the adjusted input screen meets the screen display requirement, so as to take timely measures for further adjustment or optimization.

[0044] As an embodiment of the present invention, the real-time monitoring of whether the adjusted input screen meets the screen display requirement includes: Real-time collect the optical data corresponding to the adjusted input screen; Convert the optical data into a standardized brightness matrix; Perform dynamic partition feature extraction on the standardized brightness matrix to obtain a partition brightness feature set; Based on the partition brightness feature set, evaluate whether the adjusted input screen meets the screen display requirement.

[0045] Among them, the optical data refers to the information related to the optical signal of the adjusted input image, including data such as the light intensity and color (spectral distribution) of each pixel. The standardized brightness matrix refers to the matrix obtained by arranging the collected optical data in 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.

[0046] Optionally, the optical data can be obtained by using a diode array to capture the light intensity and spectral distribution of each pixel of the adjusted image in real time at a sampling frequency of milliseconds. The partitioned brightness feature set can be obtained by using the mean clustering method to dynamically divide the standardized brightness matrix into different regions, then calculating features such as the average brightness, brightness variance, and brightness gradient of each region, and then summarizing the calculated features. Based on the partitioned brightness feature set, to evaluate whether the adjusted input image meets the image display requirements, the partitioned brightness feature set can be compared with standard parameters such as the preset brightness threshold and contrast range in the image display requirements. Based on the comparison results, evaluate whether the image meets the standard. For example, in an application scenario of a mini-led display screen, the image display requirements set by the user are: the brightness threshold is between 100 - 500 nits, and the contrast range is 800:1 - 3000:1. Then the image is divided into 4 regions for analysis: Region 1: The average brightness is 120 nits, the brightness variance is 20 (indicating less brightness fluctuation), and the calculated contrast is 1000:1; Region 2: The average brightness is 80 nits (lower than the lower limit of the brightness threshold of 100 nits), the brightness variance is 15, and the contrast is 700:1 (lower than the lower limit of the contrast range of 800:1); Region 3: The average brightness is 400 nits, the brightness variance is 30, and the contrast is 2000:1; Region 4: The average brightness is 600 nits (higher than the upper limit of the brightness threshold of 500 nits), the brightness variance is 25, and the contrast is 2500:1. Input these partitioned brightness feature sets (including data such as average brightness, brightness variance, and contrast) into a pre-trained decision tree model. Then use the decision tree model to judge whether the average brightness is within the threshold range. If the average brightness of Region 2, 80 nits, is less than 100 nits, directly determine that this region does not meet the standard; then judge the contrast. The contrast of Region 2, 700:1, is less than 800:1, and it also does not meet the standard. Considering the judgment results of all regions, since Region 2 does not meet the brightness and contrast requirements, and Region 4 does not meet the brightness requirement, finally evaluate that the adjusted input image does not meet the image display requirements.

[0047] Further, as another optional embodiment of the present invention, the conversion of the optical data into a standardized brightness matrix includes: Perform a brightness calibration conversion operation on the optical data to obtain physical brightness data; Perform normalization processing on the physical brightness data to obtain normalized brightness data; Perform geometric correction on the normalized brightness data to obtain geometric correction data; Perform matrix transformation on the geometric correction data to obtain a normalized brightness matrix.

[0048] 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 light in the actual physical scene. The normalized brightness data refers to the data obtained by normalizing the physical brightness data. The geometric correction data refers to the data obtained by performing geometric correction on the normalized brightness data.

[0049] Optionally, the physical brightness data can be obtained by performing data calibration processing on the optical data using a brightness calibration algorithm. The normalized brightness data can be obtained by mapping the physical brightness data to a fixed numerical range, such as the [0, 1] interval, using a normalization algorithm. The geometric correction data can be obtained by performing geometric data correction on the normalized brightness data using a geometric correction algorithm, such as repositioning and mapping the pixel points in the image data to restore the image to the correct geometric shape. The normalized brightness matrix can be obtained by converting the geometrically corrected data into matrix elements and constructing a matrix for the optical data using the matrix elements.

[0050] S4. When the adjusted input picture does not meet the picture display requirements, return 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.

[0051] In the embodiment of the present invention, when the adjusted input picture does not meet the picture display requirements, 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 can continuously adjust the picture parameters according to the monitoring results, enabling the picture output by the mini-led display screen to be as close as possible to the display requirements set by the user, ensuring that the picture achieves an ideal visual effect in terms of brightness, contrast, color, etc., and providing a high-quality display picture for the user.

[0052] It should be explained that the adjusted input picture not meeting the picture display requirements means that one or more display indicators of the adjusted input picture, such as brightness, contrast, color saturation, and clarity, do not meet the pre-set picture display requirement standards.

[0053] Further, as an embodiment of the present invention, after the step of configuring the picture adjustment parameters of the input picture in the mini-led algorithm board in the algorithm board adjustment component, the return execution further includes: Determine the parameter items for which the adjusted input picture does not meet the picture display requirements; Calculate the specific adjustment value corresponding to the parameter item; Based on the specific adjustment value, update the picture display parameters of the mini-led algorithm board to obtain updated display parameters; Based on the updated display parameters, perform another display parameter adjustment on the mini-led algorithm board; Monitor the picture display requirements of the mini-led algorithm board after the second display parameter adjustment; When the result of the picture display requirement monitoring meets the preset result, complete the picture display parameter adjustment of the mini-led algorithm board.

[0054] Among them, the parameter item refers to the specific index that describes that the picture display characteristics do not meet the picture display requirements, such as brightness, contrast, and color saturation. The specific adjustment value refers to the quantified adjustment amount calculated for the parameter item that does not meet the picture display requirements. The updated display parameter refers to a new set of parameters obtained by updating on the basis of the original picture display parameters of the mini-led algorithm board in combination with the specific adjustment value.

[0055] Optionally, the parameter item can be obtained by comparing each parameter (such as brightness, contrast, color saturation, etc.) of the adjusted input picture obtained by real-time monitoring with the preset picture display requirement parameters one by one to find out the items with specific differences. The specific adjustment value can be calculated according to the difference between the current value and the preset value of the parameter item that does not meet the requirements. For example, if the current brightness value is lower than the preset value, calculate the difference between the two as the brightness adjustment value. The updated display parameter can be obtained by adding the calculated specific adjustment value to the existing corresponding picture display parameters of the mini-led algorithm board.

[0056] When the result of the picture display requirement monitoring meets the preset result, it means that the monitoring result shows that all parameters are within the preset requirement range.

[0057] S5. When the adjusted input picture meets the picture display requirements, use the adjusted input picture as the final display picture.

[0058] In the embodiment of the present invention, when the adjusted input screen meets the screen display requirements, using the adjusted input screen as the final display screen can optimize the screen according to the preset display requirements, make the display content meet the user's viewing requirements, and improve user satisfaction.

[0059] Embodiment 2: As Figure 2 shown, it is a functional module diagram of a parameter adjustment device for implementing a mini-led algorithm board according to the present invention.

[0060] The parameter adjustment device 200 for implementing a mini-led algorithm board according to the present invention can be installed in an electronic device.
