[0002] With the development of monitor specialization in recent years, consumers hope that the products they buy will meet the color temperature and brightness standards. However, the difference in incoming materials from the factory often affects the consistency of the color temperature and brightness of the screen. In order to ensure that each monitor after production meets the product requirements, the color temperature of the monitor needs to be adjusted on the production line during production.

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0041] It should also be understood that the term “and / or” used in the specification and appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0042] As used in the specification and appended claims of this application, the term "if" can be interpreted as "when" or "uponce" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "uponce it is determined" or "in response to determining" or "uponce [described condition or event] is detected" or "in response to detecting [described condition or event]", depending on the context.

[0043] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0044] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0045] Since the brightness of display screens in different batches is often different, and even varies greatly. For example, the current batch of display screens to be tested involves 3 batches (i.e., batch 001, batch 002, and batch 003), among which the brightness of the display screens in batch 001 is 320 nits, the brightness of the display screens in batch 002 is 400 nits, and the brightness of the display screens in batch 003 is 300 nits. It can be seen that the brightness difference of display screens in different batches may be 80 to 100 nits, and the brightness difference between some batches is even greater. In such a case, if the same RGB initial value is provided, it is difficult to meet the color temperature standard and the brightness standard at the same time, and it is often necessary to repeatedly debug the values ​​of each RGB channel, resulting in the problem of too long debugging time.

[0046] Figure 1Shows a preferred embodiment of the present application ( Figure 1 FIG. 1 is a flow chart of a color temperature adjustment method provided in the first embodiment of the present application. For the sake of convenience, only the part related to the present embodiment is shown, which specifically includes the following steps:

[0047] S101, obtaining a first brightness value of the display under test in a preset state, wherein the preset state is characterized by a state in which the display under test operates at its maximum brightness value and maximum contrast value. Generally, the preset state is a state in which the brightness and contrast of the display under test are set to values ​​that are not affected by color temperature.

[0048] S102: Determine an RGB initial value of the display to be detected according to the first brightness value and a threshold of a preset brightness range, wherein the RGB initial value is within an RGB default range configured for the display to be detected.

[0049] In this embodiment, the preset brightness interval is characterized by the default brightness value ± the adjustable range value. Here, the default brightness value can be understood as the factory specification of the display screen. According to the requirements of different customers, the default brightness value and the default contrast value may also be different. The RGB default range and the default contrast value are the same as the default brightness value, and the factory specifications are also set according to customer requirements. The adjustable range value can be set according to the specific working conditions.

[0050] Specifically, if the first brightness value is within the preset brightness range, the RGB initial value of the display to be detected is determined to be the middle value within the RGB default range. The middle value can be a point value, or a number of values ​​located in the middle of the value range can be selected, and the average value of these values ​​is used as the middle value.

[0051] Specifically, if the first brightness value is outside the preset brightness range, the RGB initial value of the display to be detected is determined to be other values ​​within the RGB default range except the above-mentioned intermediate value, and the smaller the first brightness value is, the larger the value of the RGB initial value within the RGB default range is, so as to reduce the brightness difference between different batches of display screens and shorten the debugging time of the RGB value.

[0052] S103, setting the RGB parameter value of the display to be detected to the RGB initial value, the brightness parameter value of the display to be detected to the default brightness value, and the contrast parameter value of the display to be detected to the default contrast value, and obtaining the real-time color temperature value and real-time brightness value of the display to be detected.

[0053] S104: When the real-time color temperature value and / or the real-time brightness value are within the target range, information on the completion of color temperature adjustment is output. If the real-time color temperature value and / or the real-time brightness value are outside the target range, the RGB initial value is modified to obtain the RGB modified value and the process returns to step S103.

[0054] In this embodiment, by setting a preset brightness range and according to the relationship between the first brightness value and the preset brightness range, the brightness of the display screen to be tested can be divided into different gears and matched with the corresponding RGB initial values ​​to reduce the brightness difference between different batches of display screens, thereby shortening the debugging time of the RGB value and improving the overall adjustment efficiency.

[0055] In a specific embodiment of the present application, Figure 2 Shows a preferred embodiment of the present application ( Figure 1 The specific flow chart of the color temperature adjustment method provided in the first embodiment of the present application is shown. The method in the embodiment of the present application can be executed by a PC host computer. The PC host computer is connected to the display and the color analyzer respectively through a fixture. The color analyzer reads the maximum brightness value, maximum contrast value, default brightness value, default contrast value and preset brightness range of the display. Specifically, the following steps are included:

[0056] S201 , obtaining a first brightness value of a display to be tested in a preset state, wherein the preset state is characterized by a state in which the display to be tested operates at its maximum brightness value and maximum contrast value.

[0057] Generally, the maximum brightness value and the maximum contrast value can be selected to be any value far exceeding the default brightness value and the default contrast value, as long as a first brightness value that is not affected by the color temperature can be obtained, and the specific values ​​may not be limited. For example, the maximum brightness value and the maximum contrast value of the display to be tested are both set to 100, so that the first brightness value obtained after the display to be tested runs in this state.

[0058] S202: Compare the first brightness value with a threshold value of a preset brightness range, and obtain an RGB initial value of the display to be detected according to the comparison result.

[0059] It should be noted that the RGB initial value of the display to be tested is set corresponding to the comparison result between the first brightness value and the preset brightness range. That is, according to the comparison result between the first brightness value and the preset brightness range, the corresponding RGB initial value is configured. Among them, the comparison result between the first brightness value and the preset brightness range can be that the first brightness value is less than the minimum value of the preset brightness range, the first brightness value is greater than the maximum value of the preset brightness range, and the first brightness value is within the preset brightness range.

[0060] The following describes embodiments of configuring different RGB initial values ​​corresponding to different comparison results.

[0061] In one embodiment, step S202 specifically includes:

[0062] S2021: The first brightness value is less than a first threshold of the preset brightness range, and a first comparison result is obtained; wherein the first threshold is represented by a minimum value of the preset brightness;

[0063] S2022, according to the first comparison result, obtaining a first RGB initial value of the display to be detected, wherein the first RGB initial value is configured as the maximum value within the RGB default range of the display to be detected. Here, the RGB default range may correspond to the upper limit and lower limit of each channel of the R channel, the G channel, and the B channel, and the RGB default range may be adjusted according to the working conditions.

[0064] For example, the default brightness value is set to 350 nits, the adjustable range value is set to 20 nits, and the preset brightness interval is [330, 370]. If the first brightness value is 320 nits, the first comparison result is that the first brightness value is less than the first threshold of the preset brightness interval (i.e., the minimum value of the preset brightness is 330 nits). Further, the first RGB initial value corresponding to the first comparison result is obtained. The first RGB initial value is configured as the maximum value within the RGB default range in the display to be detected, that is, the upper limit default value of the R channel, the G channel and the B channel. At this time, the R channel value can be 128, the G channel value is 128, and the B channel value is 129.

[0065] In another embodiment, step S202 specifically includes:

[0066] S2023: the first brightness value is greater than a first threshold of the preset brightness range, and a second comparison result is obtained; wherein the first threshold is represented by a minimum value of the preset brightness;

[0067] S2024, the first brightness value is less than a second threshold of the preset brightness range, and a third comparison result is obtained; wherein the second threshold is represented by a maximum value of the preset brightness;

[0068] S2025: Acquire a second RGB initial value of the display to be detected according to the second comparison result and the third comparison result, wherein the second RGB initial value is configured as a middle value within a default RGB range of the display to be detected.

[0069] For example, the default brightness value is set to 350 nits, and the adjustable range value is set to 20 nits, then the preset brightness interval is [330, 370]. Then the first threshold, i.e., the minimum value of the preset brightness, is 330 nits, and the second threshold, i.e., the maximum value of the preset brightness, is 370 nits. If the first brightness value is 360 nits, then the second comparison result is that the first brightness value is greater than the first threshold of the preset brightness interval (i.e., the minimum value of the preset brightness, 330 nits). The third comparison result is that the first brightness value is less than the second threshold of the preset brightness interval (i.e., the maximum value of the preset brightness, 370 nits). In other words, the first brightness value of 360 nits is within the preset brightness interval [330, 370]. Further, according to the second comparison result and the third comparison result, the second RGB initial value of the display to be detected is obtained. The second RGB initial value is configured as the middle value within the RGB default range in the display to be detected, that is, the middle default value between the upper limit value and the lower limit value of the R channel, the G channel and the B channel. At this time, the R channel value is 119, the G channel value is 118, and the B channel value is 117.

[0070] In yet another embodiment, step S202 specifically includes:

[0071] S2026, the first brightness value is greater than a second threshold of the preset brightness range, and a fourth comparison result is obtained; wherein the second threshold is represented by a maximum value of the preset brightness;

[0072] S2027, obtaining a third RGB initial value of the display to be detected according to the fourth comparison result, wherein the third RGB initial value is configured as a minimum value within a default RGB range of the display to be detected.

[0073] For example, the default brightness value is set to 350 nits, the adjustable range value is set to 20 nits, and the preset brightness interval is [330, 370]. If the first brightness value is 380 nits, the fourth comparison result is that the first brightness value is greater than the second threshold of the preset brightness interval (i.e., the maximum value of the preset brightness is 370 nits). Further, the third RGB initial value corresponding to the fourth comparison result is obtained. The third RGB initial value is configured as the minimum value within the RGB default range in the display to be detected, that is, the lower limit default value of the R channel, the G channel, and the B channel. At this time, the R channel value is 107, the G channel value is 108, and the B channel value is 105.

[0074] S203, setting the RGB value, brightness value and contrast value of the display to be tested to the RGB initial value, default brightness value and default contrast value, and obtaining the current real-time color temperature value and real-time brightness value of the display to be tested.

[0075] S204, if the real-time color temperature value and the real-time brightness value are both within the target range, the color temperature adjustment is completed; wherein the target range is the standard color temperature value and the standard brightness value of the display to be tested.

[0076] For example, when the standard color temperature of 6500 is selected, the corresponding color temperature standard value coordinates are x=313, y=329. When the standard color temperature is adjusted, the corresponding color temperature standard value coordinates are also adjusted. Generally, the color temperature standard coordinates also have a corresponding error range, and the specific error value can be set according to the working conditions. For example, the error range is set to ±8, that is, the color temperature coordinate standard value is x=313±8, y=329±8.

[0077] The standard brightness value can generally be set according to the needs of customers, and is generally related to the brightness requirements of the country where the display is actually sold. If the display is to be sold in Europe, the standard brightness value is set according to the brightness requirements of Europe. If the display is to be sold in America, the standard brightness value is set according to the brightness requirements of America.

[0078] If the display screen to be tested is set to the RGB initial value, default brightness value and default contrast value, the detected real-time color temperature value and real-time brightness value are often not within the target range, and further debugging of the RGB initial value is required.

[0079] In a possible embodiment of the present application, the method provided in the embodiment of the present application further includes the following steps after step S203:

[0080] S205, if the real-time color temperature value and / or the real-time brightness value is not within the target range, modify the RGB initial value to obtain the RGB modified value;

[0081] S206, if the RGB modification value is within the RGB default range, the real-time color temperature value and the real-time brightness value of the display to be tested are reacquired according to the RGB modification value, the default brightness value and the default contrast value, and the process returns to step S203.

[0082] It should be noted that in the following steps, each time the RGB value of the display is adjusted, the brightness and color coordinates of the display will change accordingly. The brightness and color coordinates of the display can be monitored by a color analyzer, which will not be repeated in the following description.

[0083] S207, if the RGB modified value is not within the RGB default range, then the R value, G value and B value are judged respectively. Specifically, the steps include:

[0084] S2071: When the RGB modification value is outside the default range of the R value, a prompt message indicating that the color temperature R value overflows is output.

[0085] S2072: When the RGB modification value is outside the default range of the G value, a prompt message indicating that the color temperature G value has overflowed is output.

[0086] S2073: When the RGB modification value is not outside the default range of the B value, a prompt message indicating that the color temperature B value overflows is output.

[0087] It should be understood that the RGB default range is the factory specification range value of the three color channels of red, green and blue. Usually, the default ranges of the three color channels of R, G and B are the same. For example, the default range of RGB in the display is 0 to 255, and the maximum value in the default range is 255. When the RGB value of the display is adjusted to the maximum value of (255,255,255), the values ​​of the three channels of R, G and B are all the maximum values.

[0088] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0089] Corresponding to the color temperature adjustment method described in the above embodiment, Figure 3 2 is a structural block diagram of a color temperature adjustment device provided in an embodiment of the present application. For ease of description, only the parts related to the embodiment of the present application are shown.

[0091] The first acquisition unit 301 is used to acquire a first brightness value of the display to be tested in a preset state, wherein the preset state is characterized by a state in which the display to be tested operates at a maximum brightness value and a maximum contrast value within an adjustable range.

[0092] The processing unit 302 is used to determine the RGB initial value of the display to be detected according to the first brightness value and the threshold of the preset brightness range, and the RGB initial value is within the RGB default range configured for the display to be detected.

[0093] The second acquisition unit 303 is used to set the value of the RGB parameter of the display to be detected to the RGB initial value, the value of the brightness parameter of the display to be detected to the default brightness value, and the value of the contrast parameter of the display to be detected to the default contrast value, and obtain the real-time color temperature value and real-time brightness value of the display to be detected;

[0094] The output unit 304 is used to output color temperature adjustment completion information when the real-time color temperature value and / or the real-time brightness value is within the target range.

[0095] Specifically, the processing unit 302 is further configured to:

[0096] If the first brightness value is within the preset brightness range, then the RGB initial value of the display to be detected is determined to be a middle value within the RGB default range;

[0097] If the first brightness value is outside the preset brightness range, it is determined that the RGB initial value of the display to be detected is other values ​​within the RGB default range except the above-mentioned intermediate value, and the smaller the first brightness value is, the larger the value of the RGB initial value within the RGB default range is.

[0098] Optionally, the device further comprises:
