[0047] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0048] Embodiment 1

[0049] Please refer to Figure 1 This embodiment provides a display color temperature adjustment method, which at least includes the following steps:

[0050] S1: preset command mode and adjustment mode;

[0051] Among them, Figure 2 As shown, the command mode includes:

[0052] a. No value assignment or adjustment, only default initial RGB value judgment. In the application interface, it can be referred to as "no value assignment, only judgment". This command mode means: no RGB value assignment or adjustment, only initial RGB value judgment.

[0053] b. No adjustment, assign parameter default. In the application interface, it can be referred to as "No adjustment, assign parameter default". This command mode means: no judgment or adjustment is performed, only the default value is assigned to the display to be debugged.

[0054] c. The average value of the RGB values ​​of the previous N passes is used as the initial RGB value for adjustment, where N is an integer greater than or equal to 2. Assuming N is 5, it can be simply referred to as "the average value of the previous 5 OK values ​​is used as the initial value adjustment" in the application interface. This command mode means: the average value of the RGB values ​​of the previous five passes is assigned, and judgment and adjustment are performed after the assignment.

[0055] d. Use the RGB value of the previous pass as the initial RGB value for adjustment. In the application interface, it can be referred to as "use the value of the previous pass as the initial value for adjustment". This command mode means: assign the RGB value of the previous pass to the display to be debugged, and make judgments and adjustments after the assignment.

[0056] e. Use the parameter default as the initial RGB value for adjustment. In the application interface, it can be referred to as "use the parameter default as the initial value for adjustment". This command mode means: assign the default value to the display to be debugged, and then make judgments and adjustments.

[0057] f. Adjust with the default initial RGB value as the initial RGB value. In the application interface, it can be referred to as "adjust from the device initial value". This command mode means: do not assign values, and judge and adjust from the initial value of the display to be debugged.

[0058] g. Assign the RGB values ​​in the pass list as the initial RGB values ​​in sequence without adjustment. In the application interface, it can be simply referred to as "assign all the data in the OK list in sequence without adjustment". This command mode means: assign values ​​one by one from the pass list, only judging without adjustment.

[0059] h. Adjust the target RGB value calculated based on the default initial RGB value and the standard RGB value as the initial RGB value. In the application interface, it can be referred to as "calculate the RGB value and then adjust the value". This command mode means: the target RGB value calculated based on the default RGB value of the display to be debugged and the standard RGB value is assigned as the initial RGB value, and then judgment and adjustment are performed.

[0060] The command mode refers to the command instructions used in the debugging process, which can also be understood as a specific debugging plan. Users can select one of the multiple command modes to debug the color temperature of the display to be debugged according to different product conditions and different customer needs.

[0061] The adjustment mode refers to a display mode that needs to be adjusted, which includes more than two display modes and their corresponding color coordinate specifications and brightness specifications.

[0062] In some specific embodiments, Figure 3 As shown, the display modes include different display modes such as 6500k color temperature display mode, 7500k color temperature display mode, 9300k color temperature display mode, 5500k color temperature display mode, etc. In particular, the color temperature of the custom display mode is also supported to achieve the diversification of the adjustable display mode and better meet various needs.

[0063] In some specific implementations, the color coordinate specifications and brightness specifications corresponding to each display mode in the adjustment mode support customization and also support default configuration. The default configuration can be set based on the calculation result of the ratio of the maximum brightness value to the required brightness of the corresponding display mode, such as using the maximum brightness * required brightness ratio as the lower limit.

[0064] In some other specific embodiments, Figure 1 As shown, before S2, the following steps are also included:

[0065] S11: Scan and obtain a unique identifier of the display to be debugged. The unique identifier may be a barcode, a QR code or a character number with a unique identifier such as an SN number.

[0066] In this case, commissioning is triggered by scanning the unique identifier of the display to be commissioned.

[0067] In some other specific embodiments, Figure 1 As shown, in the above S1, a maximum brightness value is also preset; and before S2 and after S11 (if present), the following steps are also included:

[0068] S21: Switching the display mode of the display to a maximum brightness and contrast mode;

[0069] S22: receiving a current brightness value of the display obtained by a color analyzer, which may also include a color coordinate value;

[0070] S23: Determine whether the current brightness value meets the preset maximum brightness value;

[0071] If it meets the requirements, execute S2;

[0072] If not, then stop debugging, and output the result and reason of debugging failure. Here, preferably also include switching the display mode of the display back to the default display mode, and background record debugging log.

[0073] S2: Select the corresponding adjustment mode and command mode according to the display model to be debugged.

[0074] Here, in the adjustment mode, you can check multiple display modes at the same time for debugging, but for one display mode, you can only check one command mode.

[0075] S3: according to the selected adjustment mode, switching the display mode of the display to the first display mode;

[0076] S4: Setting the RGB value of the display according to the selected command mode;

[0077] Here, the setting of the RGB value of the display refers to setting it accordingly when it is necessary to modify the RGB value of the display based on the specific command instructions in the selected command mode.

[0078] The RGB value assigned to the display during debugging is different depending on the selected command mode. For example, in the above command mode a, there is no need to assign a value to the display, and the default RGB value of the display can be used directly for debugging; in the above command mode b, the RGB value of the display needs to be assigned to the parameter default before debugging.

[0079] S5: receiving the current color coordinates and current brightness value of the display obtained by the color analyzer;

[0080] Here, the color analyzer captures the current color coordinates and current brightness value of the display and feeds them back for analysis.

[0081] S6: respectively determining whether the current color coordinates and the current brightness value meet the color coordinate specifications and brightness specifications corresponding to the current display mode in the adjustment mode;

[0082] If the color coordinates and brightness meet the specifications, the display is controlled to store the correspondence between the current RGB value and the current display mode, and the display mode of the display is switched to the next display mode in the selected adjustment mode, and the process returns to continue executing S4 until the judgment of all display modes in the selected adjustment mode is completed.

[0083] That is, according to the selected command mode, all selected display modes are debugged to determine the corresponding RGB values ​​that pass the test.

[0084] If one of the color coordinates and brightness does not meet the specifications, one of the following is selected according to the selected command mode:

[0085] (1) Directly output the judgment result; this situation corresponds to the situation where the selected command mode is "no adjustment and only one RGB value is judged", such as command mode a and command mode b;

[0086] (2) Return to execute S4; this situation corresponds to the situation where the selected command mode is "adjust according to the set value", such as command mode g;

[0087] (3) obtaining an adjusted RGB value according to the current color coordinates and the current brightness value, and setting the RGB value of the display to the adjusted RGB value, while returning to continue executing S5; this situation corresponds to the situation where the selected command mode is "adjust according to the default adjustment method", such as command mode c, command mode d, command mode e, command mode f and command mode h.

[0088] Until all display modes in the selected adjustment mode are debugged.

[0089] It can be understood that all display modes in the selected adjustment mode need to be debugged according to the selected command mode.

[0090] In some specific implementations, after S6, the method further includes:

[0091] S7: Generate a debug log, and store the debug log and the unique identifier obtained by scanning in association.

[0092] Preferably, the debug log and the corresponding display are uniformly stored in the MES system for unified relationship to facilitate traceability.

The MED system is configured to store the debugging log of the debugging production and its corresponding display information. Through unified storage management, it is convenient to trace when needed.

[0097] In some specific implementations, the color analyzer is connected to the debugging device via a USB interface, that is, the two are connected based on a USB communication protocol. Therefore, the debugging device can be compatible with color analyzers of more brands.

[0098] In some specific implementations, the debugging device communicates and interacts with the display to be debugged based on the FTDI2232 chip through DDCCI commands. The two interact based on DDCCI commands. On the debugging device side, various settings and colors of the display can be easily fine-tuned with the help of a mouse and an intuitive interface, thereby improving the user experience of the debugging process and making it more user-friendly.

In addition, the debugging device of this embodiment can be well compatible with color analyzers of different brands, such as Chroma, Precision Measurement, Konica Minolta and other equipment.

[0100] Embodiment 3

[0101] This embodiment corresponds to the first and second embodiments, and provides a computer-readable storage medium on which a computer program is stored. When the program is executed by a processor of a debugged device, the steps included in the display color temperature debugging method described in the first embodiment above can be implemented. The specific steps are not repeated here, and please refer to the description of the first embodiment for details.

[0102] From the above description, it can be known that a person skilled in the art can understand that all or part of the processes in the above technical solutions can be realized by instructing related hardware through a computer program, and the program can be stored in a computer-readable storage medium, and when the program is executed, it can include the processes of the above methods. After being executed by the processor, the program can also achieve the beneficial effects of the corresponding methods.

[0103] The storage medium may be a magnetic disk, an optical disk, a read-only memory (ROM) or a random access memory (RAM).

[0104] Embodiment 4

[0105] This embodiment is based on any of the above embodiments and provides a specific application scenario:

[0106] After the debugging device is connected to the display to be debugged via USB, the color analyzer device to be used is selected in the software interface of the debugging device;

[0107] When debugging a device such as Figure 5 In the software interface shown, the initial data of the display to be debugged is set, and the command mode and adjustment mode matching the display are selected before starting the debugging operation. Here, it is assumed that the command mode f is selected.

[0108] The software startup of the debugging device is triggered by scanning the SN number of the display. The software sends a DDCCI command to the display through the FTDI2232 chip to switch the display mode of the display to the maximum brightness and contrast mode. The software captures the maximum brightness value and color coordinates of the display through the color analyzer. At this time, the display will return a set of data to confirm the command to the debugging device to confirm that the returned command is correct. If the maximum brightness does not meet the set value, the debugging is stopped, and a command is sent to adjust the display back to the default display mode. The debugging outputs the NG result and reason, and the debugging log is recorded in the background. If the maximum brightness meets the set value, the software sends a command again to switch the display mode of the display. After switching to the display mode under the selected adjustment mode, the display returns a switch confirmation command. After confirmation, the software starts to adjust the current display mode according to the selected command mode. The adjustment process is as follows:

[0109] According to the selected command mode, the adjustment starts with the default initial RGB value of the display as the initial RGB value, that is, there is no need to reconfigure the RGB value of the display. Then, the current color coordinates and the current brightness value of the display are obtained through the color analyzer, and it is determined whether they meet the color coordinate specifications and brightness specifications corresponding to the current display mode in the adjustment mode;

[0110] If all of them meet the requirements, the display mode adjustment is completed, and the software sends a storage command to the display. The display returns a confirmation command data indicating that the save is OK. The software will switch the display mode in turn and perform the above actions until all display modes in the selected adjustment mode are adjusted. Then the display returns to the preset factory mode and records the display's debugging data and debugging LOG to the background for storage. The storage is differentiated according to the scanned SN, and after uploading the MES debugging results, it can flow into the next process.

[0111] If one of the current color coordinates and the current brightness value does not meet the corresponding specifications, then in this display mode, according to the current color coordinates and the current brightness value returned by the color analyzer, it is judged whether a certain value in RGB needs to be increased or decreased, and then a set of RGB values ​​is regenerated; the regenerated RGB values ​​are sent to the display using a command, and after the display returns the confirmation command, the current color coordinates and the current brightness value are obtained again through the color analyzer. The software judges whether the obtained current color coordinates and the current brightness value meet the color coordinate specifications and brightness specifications corresponding to the current display mode in the adjustment mode. If both meet, the next display mode is adjusted. If not, the RGB value adjustment operation is continued until it meets the specifications of the current display mode (when the RGB value cannot meet the specifications of the mode within the upper and lower limits, the software will stop the operation, send a command to adjust the display back to the default display mode, and the background records the debugging NG results and data for easy analysis. The debugging interface outputs the NG results and uploads the results to MES).

[0112] In summary, the display color temperature debugging method and its system and medium provided by the present invention, by presetting multiple command modes and multiple adjustment modes, support display color temperature debugging according to the selected command mode and adjustment mode, can better be compatible with the color temperature debugging requirements of various display products and meet user needs; the most suitable debugging scheme can be flexibly selected for different products, and the color coordinates and brightness range can be accurately controlled according to different needs, thereby increasing the debugging time in product mass production and improving production efficiency.
