[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are protected by this application.

[0027] The method in this application can be applied to various types of displays, such as LED, QLED, LCD, OLED, microLED, and miniLED displays. Further optionally, the display can be packaged using various packaging methods such as SMD, COB, COG, and IMD.

[0028] With the development of display technology, LED displays have been applied to various fields due to their advantages such as low cost, low power consumption, high visibility, and flexible assembly. As the application of LED displays becomes more widespread, users often encounter situations where they need to adjust brightness and color.

[0029] In some scenarios, LED cabinet rental companies often borrow the same type of cabinets from other rental companies to assemble large LED displays when undertaking large-scale events. Even with the same type of cabinet, there are often significant differences in brightness and color gradation, resulting in noticeable color variations between cabinets and affecting the display effect. In such cases, it is necessary to adjust the brightness and color gradation of the LED cabinets to eliminate these differences.

[0030] In some scenarios, the brightness and color intensity of LED module beads will decrease with increasing usage time. If the aging module is replaced with a spare module, the brightness and color intensity of the spare module will still be inconsistent with the surrounding modules that have not been replaced, since the spare module is brand new. In this case, it is necessary to adjust the brightness and color intensity of the spare module to eliminate this difference.

[0031] In some scenarios, dust on the camera's CMOS sensor or lens can cause dark spots in the image. If this image is used to adjust the brightness and color of the LED display, the LEDs with normal brightness and color in the dark spots will be corrected. After correction, the LEDs in the dark spots will be too bright, causing bright spots on the LED display and affecting the user's viewing experience. In this case, it is also necessary to correct the brightness or color of the LEDs.

[0032] In some scenarios, if there are only a few faulty LEDs on a single module, repairs are usually done by replacing the LEDs. The newly replaced LEDs are often brighter than the ones that weren't replaced. In this case, it's also necessary to adjust the brightness of the individual LEDs.

[0033] In related technologies, the brightness and chromaticity adjustment of a display screen are coupled together. When adjusting the brightness and chromaticity parameters, the brightness and chromaticity will change together, which reduces the ease of use of brightness and chromaticity adjustment.

[0034] Specifically, in related technologies, luminance and chromaticity parameters can be represented as a luminance and chromaticity parameter matrix. This indicates that the brightness and chromaticity data are... in, This provides the initial luminance and chromaticity data for the red, green, and blue channels. XYZ represents the tristimulus values ​​in the color space, and Y can represent brightness. When adjusting luminance and chromaticity, any one of a1 to a9 is adjusted. This changes the tristimulus value of the corresponding color, thus altering the brightness Y of that color. out Changes occurred, and by X out Y out Z out Colorimetrics determined by each other Things will also change.

[0035] Therefore, this brightness and chromaticity adjustment method is difficult to meet the needs of adjusting only brightness and only chromaticity, and has low ease of use.

[0036] To illustrate the technical solution of this application, specific embodiments are described below.

[0037] Figure 1 This illustration shows a flowchart of a brightness and color saturation adjustment method for a display screen according to an embodiment of this application. This method can be applied to terminal devices and is suitable for situations requiring improved ease of use in brightness and color saturation adjustment. The terminal device can be a computer, mobile phone, tablet computer, or other smart device; this application does not limit its application to this type of device.

[0038] Specifically, the brightness and color adjustment method of the above-mentioned display screen may include the following steps S101 to S103.

[0039] Step S101: Obtain the complementary color parameters of the display screen to be adjusted set by the user.

[0040] Among them, the display screen to be adjusted refers to the display screen that needs to have its brightness and color adjusted. It can be the display screen that is configured on the terminal device itself, or it can be other display screens that are separate from the terminal device.

[0041] In the embodiments of this application, when a user needs to adjust the color of the display screen to be adjusted, a complementary color parameter can be set. The complementary color parameter is a parameter used to adjust the color of the display screen.

[0042] Specifically, the color display of the screen to be adjusted can be composed of N color channels, and each color channel can correspond to M complementary color parameters, where N is a positive integer greater than or equal to 1 and M is a positive integer greater than or equal to 2.

[0043] For example, N color channels can be RGB three color channels. It should be understood that RGB three color channels can be used to display different visible light on the screen. Correspondingly, the M complementary color parameters for each color channel can be RGB three complementary color parameters. If the user needs to make the display appear more reddish, they can adjust the R complementary color parameter corresponding to any color channel. If the user needs to make the display appear more greenish, they can adjust the G complementary color parameter corresponding to any color channel. Of course, based on actual needs, the user can adjust one or more complementary color parameters corresponding to multiple color channels simultaneously.

[0044] In other embodiments, the N color channels may also include color channels for RGB and other colors besides RGB (such as cyan, yellow, etc.). Similarly, the M complementary color parameters may also include complementary color parameters for RGB and other colors besides RGB. Furthermore, the number of complementary color parameters and color channels may be different, that is, M and N may not be equal, and this application does not impose any restrictions on this.

[0045] To facilitate user settings of complementary color parameters, in some implementations, the terminal device can display M initial complementary color parameters corresponding to each of the N color channels of the display screen to be adjusted on the display screen interface. Here, the operation display screen can refer to the display screen configured on the terminal device itself, which can be used to provide a visual display interface for users to easily set the complementary color parameters. The M initial complementary color parameters refer to the initial values ​​of the M complementary color parameters. These initial values ​​can be preset by the operator or stored by the terminal device after completing the previous brightness and chromaticity adjustment.

[0046] Based on the user's adjustment of the target initial complementary color parameters corresponding to the target color channel on the display interface, the terminal device can obtain the complementary color parameters set by the user. Here, the target color channel belongs to N color channels, and the target initial complementary color parameters belong to M initial complementary color parameters.

[0047] For example, please refer to Figure 2 , Figure 2A schematic diagram of the display interface on the operation screen is shown. Users can select the R color channel (target color channel) in the software interface and drag the slider 21 of the "Add Green" parameter (target initial complementary color parameter) for the R color channel. Alternatively, they can input the value in the "Add Green" input box 22 of the R color channel in the software interface, or click the "Add Green" click box 23 of the R color channel in the software interface to adjust the initial complementary color parameter of the R channel to the desired value, thus completing the setting of the complementary color parameter.

[0048] It should be noted that, Figure 2 This is merely an illustrative example. In other embodiments, users can also select the desired value on the display interface, or set the complementary color parameter through other commonly used software operation methods. Alternatively, users can input the set complementary color parameter to the terminal device through physical buttons, remote controls, or other devices configured on the terminal device. This application does not limit the specific implementation method for setting the complementary color parameter.

[0049] Step S102: Based on the complementary color parameters set by the user and the current brightness of the display screen to be adjusted, obtain the target color adjustment parameters of the display screen to be adjusted.

[0050] The target chromaticity adjustment parameter can be used to adjust the complementary color parameters of the display screen under its current brightness. In other words, the target chromaticity parameter can be used to adjust the chromaticity of the display screen while keeping its brightness constant.

[0051] Specifically, the terminal device can adjust at least one of the M initial complementary color parameters (excluding the target initial complementary color parameter) based on the complementary color parameters set by the user and the current brightness of the display screen to be adjusted, in order to obtain the adjusted complementary color parameters by the amount of change in brightness. At this time, the target chromaticity adjustment parameters may include the complementary color parameters set by the user and the adjusted complementary color parameters.

[0052] The current brightness of the display screen to be adjusted can be obtained in different ways. For example, the user can input the current brightness, the image of the display screen to be adjusted can be taken and the pixel values ​​of the image can be analyzed to obtain the current brightness, or the current brightness can be calculated using the initial brightness and color saturation data of the display screen to be adjusted and the brightness and color saturation adjustment parameters used in the past.

[0053] Step S103: Send the target chromaticity adjustment parameters to the control device of the display screen to be adjusted; or adjust the chromaticity of the display screen to be adjusted according to the target chromaticity adjustment parameters.

[0054] In some embodiments of this application, the terminal device can send target chromaticity adjustment parameters to the control device of the display screen to be adjusted, and the control device can then adjust the chromaticity of the display screen according to the target chromaticity adjustment parameters. For example, please refer to... Figure 2 As shown in the display interface, the user can click "Send". In response to the user's click, the terminal device can send the target chromaticity adjustment parameters to the control device. After receiving the target chromaticity adjustment parameters, the control device can send the target chromaticity adjustment parameters to the display screen to be adjusted. At this time, the chromaticity displayed on the display screen to be adjusted is the adjusted chromaticity, while the brightness displayed on the display screen to be adjusted remains the current brightness.

[0055] In some other embodiments of this application, the terminal device may also directly adjust the chromaticity of the display screen to be adjusted according to the target chromaticity adjustment parameters.

[0056] It should be noted that the number of displays to be adjusted at each time can be one or more. That is, the terminal device or control device can simultaneously adjust one or more displays based on the target colorimetric adjustment parameters. Furthermore, the displays to be adjusted can include a first display area and a second display area, and the terminal device can adjust only the first display area or the second display area. Optionally, the first display area and the second display area correspond to different batches of cabinets. For example, the first display area may be from the first batch of cabinets, and the second display area may be from the second batch of cabinets; the visual effect of cabinets from different batches will differ to the human eye.

[0057] In order to ensure that the final color display of the display meets the user's needs, after the color adjustment is completed, the user can reset the new complementary color parameters. The terminal device will return to the execution steps S101 to S103 to realize the cyclic color adjustment until the final color display of the display to be adjusted meets the user's needs.

[0058] In the embodiments of this application, by obtaining the complementary color parameters of the display screen to be adjusted set by the user, and obtaining the target chromaticity adjustment parameters of the display screen to be adjusted based on the complementary color parameters set by the user and the current brightness of the display screen to be adjusted, the target chromaticity adjustment parameters are then sent to the control device of the display screen to be adjusted, or the chromaticity of the display screen to be adjusted is adjusted according to the target chromaticity adjustment parameters. The target chromaticity adjustment parameters are used to adjust the complementary color parameters of the display screen to be adjusted at the current brightness. In this way, the terminal device can adjust the chromaticity while keeping the brightness of the display screen to be adjusted unchanged, which solves the problem of mutual coupling between brightness adjustment and chromaticity adjustment and improves the ease of use of brightness and chromaticity adjustment of the display screen.

[0059] In other embodiments of this application, such as Figure 3As shown, the terminal device can also adjust the brightness of the display screen to be adjusted through the following steps.

[0060] Step S301: Obtain the brightness adjustment parameters of the display screen to be adjusted set by the user.

[0061] The brightness adjustment parameter can be used to adjust the brightness of the display screen under the current chromaticity. In other words, the brightness adjustment parameter can be used to adjust the brightness of the display screen without changing its chromaticity.

[0062] Specifically, the brightness of the operating display screen can also be composed of the brightness of N color channels. The terminal device can display on the operating display screen the brightness parameters corresponding to each of the N color channels of the display screen to be adjusted, and the M initial complementary color parameters corresponding to each color channel. Based on the user's adjustment operation on the display screen regarding the initial brightness parameters corresponding to the target color channel, the terminal device can obtain the brightness adjustment parameters set by the user. For example, please refer to... Figure 2 The display interface shows the brightness parameter "Brightness" for the R color channel, as well as the three initial complementary color coefficients for the R color channel: "Main Coefficient," "Blue Complement," and "Green Complement." Users can adjust the brightness parameters by dragging the slider for the R color channel "Brightness," entering values ​​in the input box, or clicking the click box.

[0063] It should be understood that other acquisition methods described in step S101 also apply to step S301, and will not be elaborated upon in this application.

[0064] Step S302: Send brightness adjustment parameters to the control device of the display screen to be adjusted; or adjust the brightness of the display screen to be adjusted according to the brightness adjustment parameters.

[0065] In some embodiments of this application, the terminal device can send brightness adjustment parameters to the control device of the display screen to be adjusted, and the control device adjusts the brightness of the display screen according to the brightness adjustment parameters. For example, please refer to... Figure 2 As shown in the display interface, the user can click "Send". In response to the click operation, the terminal device can send the brightness adjustment parameters to the control device. After receiving the brightness adjustment parameters, the control device can send the brightness adjustment parameters to the display screen to be adjusted for display. At this time, the brightness displayed on the display screen to be adjusted is the adjusted brightness.

[0066] In some other embodiments of this application, the terminal device may also directly adjust the brightness of the display screen to be adjusted according to the brightness adjustment parameters.

[0067] Similarly, the number of displays to be adjusted each time can be one or more. In other words, the terminal device or control device can adjust one or more displays to be adjusted simultaneously based on the brightness adjustment parameters.

[0068] To ensure that the final brightness of the display screen meets the user's needs, after completing this color adjustment, the user can reset the new brightness adjustment parameters. The terminal device will then return to steps S301 to S302 to perform cyclic brightness adjustment until the final brightness of the display screen meets the user's needs.

[0069] In the embodiments of this application, by obtaining the brightness adjustment parameters of the display screen to be adjusted set by the user and sending the brightness adjustment parameters to the control device of the display screen to be adjusted, or by adjusting the brightness of the display screen to be adjusted according to the brightness adjustment parameters, the terminal device can adjust the brightness while keeping the chromaticity of the display screen to be adjusted unchanged, thus solving the problem of mutual coupling between brightness adjustment and chromaticity adjustment and improving the ease of use of brightness and chromaticity adjustment of the display screen.

[0070] The specific processes for brightness and chromaticity adjustment are explained below.

[0071] Compared with related technologies, this application decouples the luminance and chrominance parameters into chrominance adjustment parameter C and luminance adjustment parameter L, which together determine the luminance and chrominance data when the final display screen outputs the data.

[0072] The color adjustment process is as follows:

[0073] When N=M=3, the chromaticity adjustment parameter C can be expressed as: All elements within the chromaticity adjustment parameter C (C 11 C 12 ..., C 33 ) represent a complementary color parameter.

[0074] Specifically, each column in the chroma adjustment parameter C represents a color channel. Each column contains three complementary color coefficients: two secondary complementary color coefficients and one primary complementary color coefficient. The primary complementary color coefficient is located on the main diagonal of chroma adjustment parameter C and is the complementary color to the color channel. In other words, C... 11 C 22 C 33 These are the principal complementary color parameters for the R, G, and B color channels, respectively. 21 C 31 These are the two complementary color parameters of the R color channel, C. 12 C 32 These are the two complementary color parameters of the G color channel, C. 13 C 23These are the two complementary color parameters of the B color channel.

[0075] Accordingly, the M initial complementary color parameters can include initial primary coefficient complementary color parameters and two initial secondary coefficient complementary color parameters. Figure 2 For example, before the user adjusts the color, the value of the "major coefficient" in the display interface is the initial major coefficient complementary color parameter of the R color channel, and the values ​​of "complementary green" and "complementary blue" in the display interface are the two initial secondary coefficient complementary color parameters of the R color channel.

[0076] The terminal device can obtain the user-set secondary coefficient complementary color parameters by adjusting at least one of the two initial secondary coefficient complementary color parameters on the display interface. Figure 2 To continue with the example, users can adjust one of the values ​​for "Green Supplement" and "Blue Supplement" in the display interface to obtain the user-defined secondary color coefficient parameter. At this point, the initial chromaticity adjustment parameter C... 21 C 31 At least one of them changes.

[0077] Then, based on the user-set complementary color parameters and the current brightness, the brightness change between the brightness of the display screen to be adjusted after adjusting the user-set complementary color parameters and the current brightness is calculated, so as to determine the adjusted principal coefficient complementary color parameters based on the brightness change.

[0078] Specifically, based on the user-set secondary coefficient complementary color parameters and the current brightness, the terminal device can adjust the initial primary coefficient complementary color parameters corresponding to the target color channel to obtain the adjusted primary coefficient complementary color parameters, and then obtain the target chromaticity parameter matrix. The target chromaticity adjustment parameters may include the user-set secondary coefficient adjustment parameters and the adjusted primary coefficient complementary color parameters.

[0079] In other words, when C 21 and / or C 31 Changes occur, and to compensate for these changes in brightness, the terminal device can adjust the settings based on the user-defined C. 21 and / or C 31 And the current brightness of the display screen to be adjusted, for the "major coefficient" (C) in the display interface. 11 The value of ) is automatically adjusted to obtain the adjusted main coefficient complementary color parameter, and then the C value set by the user is obtained. 21 and / or C 31 and the adjusted C 11 The target chromaticity parameter matrix is ​​formed.

[0080] Please refer to this as well. Figure 2 and Figure 4 , Figure 2This is a schematic diagram of the software interface before the user sets the complementary color parameters for the display screen to be adjusted, where "Blue Complement" is 0 and "Main Coefficient" is 2048. For example... Figure 4 As shown, after the user sets "Mana Refill" to "5", C 31 When changes occur, the terminal device automatically adjusts C to compensate for the changes in brightness. 11 The principal coefficient has been adjusted from 2048 to 2044.

[0081] It should be understood that, for C 12 C 32 C 13 C 23 The principle of setting up is the same as described above. Figure 2 Similar to the example, users can [use C] 21 C 31 C 12 C 32 C 13 C 23 One or more of the parameters can be set, and the terminal device can adjust C based on the user-set secondary color coefficients and the current brightness. 11 C 22 C 33 At least one of them is used to obtain the target chromaticity adjustment parameter.

[0082] Of course, in other implementations, the user can also configure C. 11 C 22 C 33 Configure the terminal device to process the user's settings (C). 11 C 22 C 33 Then, automatic adjustments are made to obtain the target color adjustment parameters.

[0083] Furthermore, after adjusting the complementary color parameters of the main coefficients, the terminal device can update the values ​​on the display screen to provide users with a visual representation of the adjustment process.

[0084] For details, please refer to Figure 5 The process of determining the target chromaticity adjustment parameters by the terminal device may include the following steps S501 to S502.

[0085] Step S501: Based on the complementary color parameters set by the user and the current brightness, calculate the brightness change between the brightness of the display screen to be adjusted after adjusting the complementary color parameters set by the user and the current brightness.

[0086] Specifically, the terminal device can obtain the color gamut information of the display screen to be adjusted, and determine the brightness weight of each of the N color channels based on the color gamut information.

[0087] Color gamut is a method of encoding colors. Color gamut information refers to the color gamut standard that the display screen conforms to, such as the universal color standard (standard Red Green Blue, sRGB), the National Television Standards Committee (NTSC), the DCI-P3 standard, or the Adobe RGB standard. Terminal devices can obtain preset color gamut information or color gamut information collected by a colorimeter; this application does not impose any restrictions on this.

[0088] The luminance weights of each color channel may be the same or different for each color gamut. Terminal devices can determine the luminance weight of each color channel based on a mapping table between color gamut information and luminance weights. Taking the DCI-P3 color gamut as an example, luminance Y = aY R +bY G +cY B The luminance weight a for the R channel is 0.209491678; the luminance weight b for the G channel is 0.721595254; and the luminance weight c for the B channel is 0.072192315.

[0089] Therefore, based on the user-set complementary color parameters, other unadjusted complementary color parameters, and the brightness weights a, b, and c of each of the N color channels, the terminal device can calculate the brightness value Y to be corrected using a weighted average. des Brightness Y to be corrected des This refers to the brightness of the display screen after adjusting the complementary color parameters set by the user.

[0090] At this point, the brightness value Y to be corrected des and current brightness Y org By subtracting the values, we can obtain the change in brightness ΔY.

[0091] Step S502: Determine the target chromaticity adjustment parameters based on the amount of brightness change.

[0092] Specifically, the initial principal coefficient complementary color parameters corresponding to the target color channel can be adjusted according to the amount of brightness change to obtain the adjusted principal coefficient complementary color parameters. Then, the target chromaticity adjustment parameters can be determined by the adjusted principal coefficient complementary color parameters and the complementary color parameters set by the user.

[0093] For example, if the initial chromaticity adjustment parameter is The user will set the complementary color parameter C 21 Set to 0.5, that is At this point, the brightness value to be corrected in the R channel is... Therefore, adjusting the brightness of the R color channel before and after is... Become Therefore, according to Y = aY R +bY G +cY B It can be seen that, in order to ensure that the brightness remains constant, the terminal device needs to adjust the overall brightness to compensate for the change in brightness on the R color channel. Now the R color channel has been added The brightness, according to Y = aY R +bY G +cY B Relationships can be increased The brightness needs to be reduced by a factor of k. Then, the initial principal coefficient complementary color parameter C of the R color channel is... 11 Subtract k and adjust to 1-k. That is, the target chromaticity adjustment parameter is:

[0094] In the embodiments of this application, the adjusted luminance and chrominance data It can be represented as L represents the brightness adjustment parameter, and C represents the target chromaticity parameter.

[0095] Initial brightness and chromaticity data Decomposed into RGB three color channels Assuming no brightness adjustment was made this time, L is the initial value. So, the adjusted luminance and chromaticity data are:

[0096]

[0097] At this point, the adjusted brightness is the same as the current brightness, and since chromaticity can be expressed as... in, Since the factors of change in X, Y, and Z are different before and after adjustment, the factors of change in the numerator and denominator of x and y are different, resulting in different chromaticity values. Things have changed.

[0098] The brightness adjustment process is as follows:

[0099] When N=M=3, the brightness adjustment parameter L can be expressed as: The brightness adjustment parameter L has all elements except those on the main diagonal set to 0, and the elements on the main diagonal set L... 11 L 22 and L 33 These represent the brightness parameters corresponding to a color channel, and together they affect the brightness data of the display screen. Specifically, L... 11 L is the brightness parameter for the R color channel. 22 L is the brightness parameter of the G color channel. 33 This is the brightness parameter for the B color channel.

[0100] by Figure 2 For example, before the user adjusts the brightness, the value of the "brightness parameter" in the display interface is the initial brightness parameter of the R color channel.

[0101] The terminal device can obtain the brightness adjustment parameters set by the user based on the user's adjustment of the initial brightness parameters corresponding to the target color channel on the display interface. Figure 2 To continue with the example, users can adjust the value of the "brightness parameter" in the R color channel of the display interface. At this time, the L value in the brightness adjustment parameter L will be adjusted. 11 The settings change, and the brightness adjustment parameters set by the user are obtained.

[0102] It should be understood that, for L 22 and L 33 The principle of setting up is the same as described above. Figure 2 Similar to the example, users can target L 11 L 22 and L 33 One or more of these settings can be configured to adjust the brightness.

[0103] For example, if the initial brightness adjustment parameter is Assuming the user adjusts the brightness parameter L 11 Adjusted to 2, that is Initial brightness and chromaticity data Decomposed into components of three color channels Assuming no chroma adjustment was made in this case, C is the initial value. So, the adjusted luminance and chromaticity data are:

[0104]

[0105] At this point, adjustments before and after... Become Brightness changes. And since chromaticity can be represented as... in, Since the factors of change for X, Y, and Z are the same before and after adjustment, the factors of change for the numerators and denominators of x and y are also the same. After simplification, the result can be calculated as follows. It is the same as before the adjustment; the color has not changed.

[0106] As can be seen from the foregoing description, in the embodiments of this application, the brightness adjustment and chromaticity adjustment of the terminal device are decoupled from each other. Users can choose to adjust only the brightness or only the chromaticity based on actual conditions, or they can adjust both brightness and chromaticity together. This adapts to different application scenarios, and the brightness and chromaticity adjustment is highly user-friendly. Figure 2Taking this as an example, users can set only one of "Green Supplement", "Blue Supplement", "Brightness Parameter" and "Main Coefficient"; they can also set "Green Supplement" and "Brightness Parameter" at the same time to adjust the brightness and chroma on the R channel; they can also set "Green Supplement" in the R color channel interface and set "Brightness Parameter" in the B color channel interface to adjust the chroma on the R channel and the brightness on the B channel.

[0107] It should be noted that, for the sake of simplicity, the aforementioned method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, because according to this application, some steps can be performed in other orders.
