For example, at least one of a, b, c (item) may represent: "a", "b", "c", "a and b", "a and c", "b and c" and "a, b and c", wherein a, b, c may be single or plural. Similarly, the term "at least two" means two or more, and the meaning of the expression is similar to the term "at least one".

The display control method, the display control device, the electronic equipment and the readable storage medium provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

The display control method provided by the embodiment of the application can be applied to a scene of using the electronic equipment by a user.

If the electronic device has turned on the CABC function, the electronic device may obtain a corresponding adjustment percentage, for example, 50%, according to the CABC mode in which the electronic device is located, and adjust the brightness values of all the backlight lamps of the backlight plate by 50%, so as to reduce the backlight power consumption of the backlight plate, thereby improving the cruising ability of the electronic device. However, since the situation that the picture 1 is a landscape picture may occur, the vividness of some colors in the picture 1 may be high, and thus, after the electronic device adjusts the brightness values of all the backlight lamps of the backlight plate, the vividness of the certain colors may be greatly reduced, thereby causing the image quality of the picture 1 to be greatly reduced.

However, in the embodiment of the present application, the backlight panel of the electronic device includes at least two groups of backlights with different colors, so that after the electronic device obtains an adjustment percentage (i.e., 50%), the electronic device may obtain at least two gray-scale data sets of the picture 1, where the at least two gray-scale data sets correspond to at least two colors in the picture 1, each gray-scale data set includes a gray-scale value corresponding to each pixel of one color, determine at least two new adjustment parameters according to the at least two gray-scale data sets and 50%, and respectively adjust the brightness values of the N groups of backlights corresponding to the N colors according to the at least two new adjustment parameters. It will be appreciated that, since the electronic device determines the first adjustment parameter corresponding to one color according to each gray-scale data set including the gray-scale value of the pixel point corresponding to each color in the picture 1, that is, the new adjustment parameter of each color is related to the gray-scale value of the pixel point of each color, in this way, in the case that the vividness degree of some colors in the picture 1 is higher, the new adjustment parameters of some colors may be different from the new adjustment parameters of other colors, but not the adjustment parameters of all colors are the same, and therefore, after the electronic device adjusts the brightness values of the different groups of backlight lamps of different colors according to the different new adjustment parameters, the vividness degree of some colors is reduced less, and thus the image quality of the picture 1 is reduced less.

In the display control method provided by the embodiment of the application, the execution subject may be a display control device, or an electronic device, or a functional module or entity in the electronic device. In the embodiment of the application, the display control method provided by the embodiment of the application is described by taking the electronic equipment as an example to execute the display control method.

As shown in fig. 1, a display control method provided in an embodiment of the present application may include the following steps 101 to 103.

Step 101, the electronic device obtains N gray-scale data sets of a picture to be displayed.

In some embodiments of the present application, the electronic device may include a target display module, where the target display module includes the above-mentioned backlight panel, a target display screen, and a display driving chip, and the display driving chip is electrically connected to the target display screen and the above-mentioned backlight panel, respectively.

The target display screen may specifically be any one of the following: the liquid crystal display (Liquid Crystal Display, LCD) and the Organic Light-emitting diode (Organic Light-EmittingDiode, OLED) display may be other types of display, and embodiments of the present application are not limited herein. The target display screen is used for displaying pictures. The backlight plate is used for providing a backlight effect for a picture displayed by the target display screen. The display driving chip is used for adjusting the effect of a picture displayed by the target display screen and/or adjusting the backlight effect provided by the backlight plate.

In some embodiments of the present application, the N groups of backlight lamps may include at least one of: a red backlight lamp set, a green backlight lamp set and a blue backlight lamp set. The backlight panel may further include N driving chips, each driving chip being used for driving a group of backlight lamps, respectively. It will be appreciated that N may be 3.

For example, fig. 2 shows a schematic structural diagram of a target display module according to an embodiment of the present application. As shown in fig. 2, the target display module includes a backlight plate, a target display screen and a display driving chip, wherein the target display screen is electrically connected with the display driving chip, and the backlight plate is electrically connected with the display driving chip; the display driving chip is also electrically connected with a main processor of the electronic equipment; the backlight plate comprises a power management chip and N driving chips, such as a red light driving chip, a green light driving chip and a blue light driving chip; therefore, the display driving chip can adjust the effect of the picture displayed by the target display screen according to the indication of the main processor, and/or adjust the backlight effect provided by the backlight plate through the power management chip and the N driving chips.

In some embodiments of the present application, the electronic device may acquire N gray-scale data sets of a frame to be displayed when the electronic device turns on the CABC function.

Optionally, in conjunction with fig. 2, when the electronic device turns on the CABC function, the main processor of the electronic device may send a CABC enabling command to the power management chip of the backlight panel, so that the power management chip may identify a control signal sent by the CABC module of the display driving chip, and the main processor of the electronic device may send a CABC setting parameter to the CABC module, where the CABC setting parameter is used to control the CABC module to be in an operating state. The main processor of the electronic device may send the picture data of the picture to be displayed to the image register (GRAM) of the display driving chip, so that the decoding unit of the GRAM may decode the picture data and send the decoded picture data to the storage unit of the GRAM, so that the storage unit may send the decoded picture data to the communication unit of the content analysis module of the display driving chip through the communication unit of the GRAM, so that the communication unit of the content analysis module may obtain N gray-scale data sets according to the decoded picture data and send the N gray-scale data sets to the N data temporary storage units, for example, send the gray-scale value of each pixel including red to the red gray-scale data temporary storage unit, send the gray-scale value of each pixel including green to the green gray-scale data temporary storage unit, and send the gray-scale value of each pixel including blue to the blue gray-scale data temporary storage unit, so that the electronic device may obtain the N gray-scale data sets.

In the embodiment of the present application, the N gray-scale data sets correspond to N colors in the frame to be displayed, and each gray-scale data set includes gray-scale values of each pixel point corresponding to one color in the frame to be displayed.

In some embodiments of the present application, each of the N gray-scale data sets may specifically be a gray-scale value matrix, and each of matrix elements in each of the gray-scale value matrices is respectively: gray scale value of a pixel point corresponding to a color.

In some embodiments of the present application, the electronic device may sequentially read the gray-scale values of each pixel corresponding to one color in the decoded picture data through the communication unit of the content analysis module to obtain a gray-scale data set, and then read the gray-scale values of each pixel of the other color in the decoded picture data to obtain another gray-scale data set, and so on to obtain N gray-scale data sets.

It can be understood that the electronic device may split and stream the decoded picture data through the communication unit of the content analysis module, so as to obtain N gray-scale data sets.

Step 102, the electronic device determines N first adjustment parameters according to the N gray-scale data sets.

In the embodiment of the present application, each of the N first adjustment parameters is an adjustment parameter corresponding to one color of a gray-scale data set.

In the embodiment of the present application, for each of the N first adjustment parameters, one first adjustment parameter is used to adjust the brightness parameter of a group of backlight lamps of one color. The luminance parameter may specifically be a luminance value.

In some embodiments of the present application, for each of the N first adjustment parameters, one first adjustment parameter may specifically be a brightness Gain parameter BL-Gain, one first adjustment parameter may be an adjustment percentage, and one first adjustment parameter may be different from the other adjustment parameters. Wherein, the other adjustment parameters may be: of the N first adjustment parameters, adjustment parameters other than the one first adjustment parameter are used.

In some embodiments of the present application, the electronic device may determine one target value according to the gray-scale values of the respective pixels in each gray-scale data set, and then determine one first adjustment parameter corresponding to the one target value to determine N first adjustment parameters. Wherein the target value may be any one of the following: the gray scale value average (e.g., the first gray scale value in the embodiment described below), the gray scale value variance value, and the gray scale median value, each target value may represent the gray scale value of a pixel corresponding to one color.

Optionally, for each of the N target values, the larger one target value, the smaller one first adjustment parameter the electronic device determines according to the one target value.

It can be understood that the larger the gray scale value of the pixel point corresponding to a certain color is, the larger the corresponding target value is, the more likely the certain color is the dominant color of the picture to be displayed, i.e. the vividness of the certain color is higher, and lowering a certain group of backlight lamps of the certain color can cause the picture quality of the picture to be displayed to be greatly reduced, so that the electronic device can adopt a smaller first adjustment parameter to lower a certain group of backlight lamps of the certain color so as to reduce the backlight power consumption of the backlight plate while ensuring the picture quality of the picture to be displayed; the smaller the gray scale value of the pixel point corresponding to a certain color is, the smaller the corresponding target value is, the more likely the certain color is the auxiliary tone of the picture to be displayed, namely the brightness degree of the certain color is lower, and turning down a certain group of backlight lamps of the certain color does not cause the picture quality of the picture to be displayed to be greatly reduced, so that the electronic equipment can adopt a larger first adjustment parameter to turn down a certain group of backlight lamps of the certain color so as to further reduce the backlight power consumption of the backlight plate.

Optionally, assuming that the N gray-scale data sets include a red gray-scale data set D0-R, a green gray-scale data set D0-G, and a blue gray-scale data set D0-B, in connection with fig. 2, after the electronic device may obtain D0-R, D0-G and D0-B according to the decoded picture data through the communication unit of the content analysis module, the electronic device may store D0-R in the red gray-scale data temporary storage unit of the content analysis module, store D0-G in the green gray-scale data temporary storage unit of the content analysis module, and store D0-B in the blue gray-scale data temporary storage unit of the content analysis module, so that the electronic device may determine a target value through the red gray-scale data analysis module of the content analysis module according to D0-R in the red gray-scale data temporary storage unit, determine a first adjustment parameter corresponding to the one target value, and determine another target value through the green gray-scale data analysis module of the content analysis module according to D0-G in the green gray-scale data temporary storage unit, and determine another target value corresponding to another target value in the blue gray-scale data temporary storage unit of the content analysis module, and determine another adjustment parameter corresponding to another target value in the blue gray-scale data temporary storage unit of the content analysis module.

The specific scheme of determining the target value by the electronic device will be illustrated by taking the target value as a gray-scale value average value as an example.

In some embodiments of the present application, as shown in fig. 3 in conjunction with fig. 1, before the step 102, the display control method provided in the embodiment of the present application may further include the following step 201, and the step 102 may be specifically implemented by the following step 102 a.

Step 201, the electronic device obtains a second adjustment parameter corresponding to the first CABC mode where the electronic device is located.

In some embodiments of the present application, after the above CABC module is in a working state, the main processor of the electronic device may send, to the CABC module, a type of a display element in a picture displayed by the target display screen, so that the CABC module may determine, according to the type of the display element, a first CABC mode in which the electronic device is located, and obtain a second adjustment parameter corresponding to the first CABC mode.

Alternatively, the first CABC mode may be any one of the following: user Interface (UI) mode, video mode, image mode, etc.

Optionally, the type of the display element may include at least one of the following: interface type, video type, image type, etc.

Optionally, the electronic device may determine, by using the CABC module and using at least one first correspondence, a first CABC mode corresponding to the type of the display element. Each first corresponding relation is a corresponding relation between one type and one mode.

For example, assuming that a video window is displayed in a picture displayed on a target display screen of the electronic device, that is, a type of a display element in the picture is a video type, the electronic device may determine, from at least one first correspondence, one type that is the same as the video type, and then determine, as a first CABC mode in which the electronic device is located, for example, a video mode, that corresponds to the one type, that is, the first CABC mode in which the electronic device is located is a video mode.

In some embodiments of the present application, the second adjustment parameter may be an adjustment percentage.

In some embodiments of the present application, the electronic device may determine, through the above CABC module, a second adjustment parameter corresponding to the first CABC mode using at least one second correspondence. Each second corresponding relation is a corresponding relation between one mode and one adjustment parameter.

In some embodiments of the present application, after the CABC module determines the second adjustment parameter, in conjunction with fig. 2, the control unit of the CABC module may send the second adjustment parameter to the communication module of the CABC module, so that the communication module of the CABC module may send the second adjustment parameter to the communication module of the content analysis module.

Step 102a, the electronic device determines the corresponding first adjustment parameters according to each gray-scale data set and the second adjustment parameters.

In some embodiments of the present application, in connection with fig. 2, after the communication module of the content analysis module receives the second adjustment parameter, the red gray scale data analysis unit of the content analysis module may determine one first adjustment parameter, such as a red brightness Gain parameter BL-Gain-R, corresponding to the one gray scale data set according to the one gray scale data set (such as a gray scale data set including a gray scale value of each pixel of red) and the second adjustment parameter, the green gray scale data analysis unit of the content analysis module may determine another first adjustment parameter, such as a green brightness Gain parameter BL-Gain-G, corresponding to the another gray scale data set according to the another gray scale data set (such as a gray scale data set including a gray scale value of each pixel of blue) and the second adjustment parameter, and the blue gray scale data analysis unit of the content analysis module may determine another first adjustment parameter, such as a blue Gain-BL parameter, corresponding to the another gray scale data set according to the another gray scale data set (such as a gray scale data set including a gray scale value of each pixel of blue).

In some embodiments of the present application, the electronic device may determine a target value according to the gray-scale value of each pixel in each gray-scale data set, and then determine the corresponding first adjustment parameter according to the magnitude relation between each target value and the preset gray-scale value and the second adjustment parameter.

It can be understood that the larger the gray-scale value of the pixel point corresponding to a certain color is, the larger the corresponding target value is, so that it can be determined whether the certain color is a dominant color, i.e. whether the vividness of the certain color is higher, through the magnitude relation between the corresponding target value and the preset gray-scale value, so as to determine the corresponding first adjustment parameter according to the second adjustment parameter.

In some embodiments of the present application, in conjunction with fig. 2, after the red-gray-level data analysis unit of the content analysis module determines the red-brightness Gain parameter BL-Gain-R, the red-gray-level data analysis unit transfers the red-brightness Gain parameter BL-Gain-R to the backlight red-brightness Gain unit, and after the green-gray-level data analysis unit of the content analysis module determines the green-brightness Gain parameter BL-Gain-G, the green-gray-level data analysis unit transfers the green-brightness Gain parameter BL-Gain-G to the backlight green-brightness Gain unit, and after the blue-gray-level data analysis unit of the content analysis module determines the blue-brightness Gain parameter BL-Gain-B, the blue-gray-level data analysis unit transfers the blue-brightness Gain parameter BL-Gain-B to the backlight blue-brightness Gain unit.

Therefore, the electronic device can acquire the second adjustment parameters corresponding to the first CABC mode, and then adaptively adjust the second adjustment parameters according to each gray-scale data set, so that the first adjustment parameters of some colors can be different from the first adjustment parameters of other colors, but not all the adjustment parameters of all the colors are the same.

A specific scheme of the electronic device determining each first adjustment parameter will be exemplified below.

In some embodiments of the present application, the step 102a may be specifically implemented by the following steps 102a1 to 102a 4.

Step 102a1, the electronic device determines a first gray-scale value according to each gray-scale data set.

In the embodiment of the application, each first gray-scale value is the average value of the gray-scale values of the pixel points corresponding to one gray-scale data set.

In some embodiments of the present application, the electronic device may determine a sum of gray-scale values of the respective pixels in each gray-scale data set, and then determine a ratio of the sum of gray-scale values of the respective pixels in each gray-scale data set to the number of the respective pixels in each gray-scale data set as a first gray-scale value.

Step 102a2, the electronic device determines whether a first gray-scale value is greater than or equal to a preset gray-scale value.

In the embodiment of the present application, the first gray-scale value may be any one of N gray-scale values.

In some embodiments of the present application, the preset gray-scale value may be any one of the following: the method comprises the steps of pre-storing gray scale values in the electronic equipment, acquiring the gray scale values from the server by the electronic equipment and acquiring the gray scale values from other electronic equipment by the electronic equipment.

Optionally, the preset gray-scale value may specifically be: determined from a plurality of pictures differing in main tone. Specifically, the backlight of the color corresponding to the main tone of each of the plurality of pictures may be respectively turned up, and the image quality of each of the displayed pictures may be observed, so that at least one picture with a large degradation of the image quality may be determined, and thus the electronic device may determine, as the preset gray-scale value, the average value of the gray-scale values of the pixels of the color corresponding to the main tone of the at least one picture.

In some embodiments of the present application, the electronic device may determine whether the one first gray-scale value is greater than or equal to the preset gray-scale value according to whether a difference between the one first gray-scale value and the preset gray-scale value is greater than or equal to 0.

In step 102a3, when a first gray level value is greater than or equal to a preset gray level value, the electronic device determines a difference between the second adjustment parameter and the first preset value as a first adjustment parameter.

In the embodiment of the present application, the first preset value is greater than 0. It will be appreciated that the difference between the second adjustment parameter and the first preset value is smaller than the second adjustment parameter.

In some embodiments of the present application, the first preset value may be any one of the following: a preset value corresponding to the first CABC mode, a preset value determined by the electronic device, and the like.

In the embodiment of the present application, if the above-mentioned one first gray-scale value is greater than or equal to the preset gray-scale value, the color corresponding to the one first gray-scale value may be considered as the dominant color of the picture to be displayed, so that the electronic device may determine the difference between the second adjustment parameter and the first preset value as one first adjustment parameter, i.e. determine the smaller adjustment parameter as the one first adjustment parameter.

It should be noted that, in the above embodiment, taking one gray-scale data set as an example for illustration, if at least two first gray-scale values corresponding to at least two gray-scale data sets are all greater than or equal to a preset gray-scale value, the electronic device may execute the step 102a3 for each first gray-scale value to obtain a first adjustment parameter corresponding to one color, and it can be understood that the color of the superposition of at least two colors corresponding to the at least two gray-scale data sets may be the dominant hue of the picture to be displayed; or if at least two first gray-scale values corresponding to at least two gray-scale data sets are smaller than the preset gray-scale value, the electronic device may execute the step 102a4 for each first gray-scale value to obtain the first adjustment parameter corresponding to one color.

Therefore, the electronic device can determine that a certain color is likely to be the main tone of the picture to be displayed under the condition that the first gray level value of the certain color is larger than or equal to the preset gray level value, and determine the smaller adjustment parameter as the first adjustment parameter of the certain color, so that after the electronic device adjusts down the backlight light of the certain color according to the first adjustment parameter of the certain color, the picture quality of the picture to be displayed is less degraded, and the cruising ability of the electronic device can be improved, and the display effect of the electronic device can be improved.

In step 102a4, the electronic device determines the sum of the second adjustment parameter and the second preset value as a first adjustment parameter when a first gray level value is smaller than the preset gray level value.

In the embodiment of the present application, the second preset value is greater than 0. It will be appreciated that the sum of the second adjustment parameter and the first preset value is greater than the second adjustment parameter.

In some embodiments of the present application, the second preset value may be any one of the following: a preset value corresponding to the first CABC mode, a preset value determined by the electronic device, and the like. The second preset value may be the same as or different from the first preset value.

In the embodiment of the present application, if the above-mentioned one first gray-scale value is smaller than the preset gray-scale value, the color corresponding to the one first gray-scale value may be considered as an auxiliary color of the picture to be displayed, so that the electronic device may determine the sum of the second adjustment parameter and the first preset value as one first adjustment parameter, that is, determine the larger adjustment parameter as the one first adjustment parameter.

Therefore, the electronic device can determine that a certain color is likely to be an auxiliary tone of the picture to be displayed under the condition that the first gray level value of the certain color is smaller than the preset gray level value, and determine a larger adjustment parameter as the first adjustment parameter of the certain color, so that after the electronic device adjusts down the backlight lamp of the certain color according to the first adjustment parameter of the certain color, the picture quality of the picture to be displayed is less degraded, and the backlight power consumption of the backlight plate is greatly reduced, and the display effect of the electronic device can be improved while the endurance of the electronic device is improved.

In some embodiments of the present application, in conjunction with fig. 2, after the electronic device generates the backlight red control signal C-BL-R2, the backlight green control signal C-BL-G2, and the backlight blue control signal, the power management chip may send the backlight red control signal C-BL-R2 to the backlight red driving chip, so that the backlight red driving chip may supply power to a group of backlight lamps (i.e., a backlight red lamp group) according to the corresponding power supply parameters, so as to reduce the brightness parameters of the backlight red lamp group, and the power management chip may send the backlight green control signal C-BL-G2 to the backlight green driving chip, so that the backlight green driving chip may supply power to another group of backlight lamps (i.e., a backlight green lamp group) according to the corresponding power supply parameters, so as to reduce the brightness parameters of the backlight green lamp group, and the power management chip may send the backlight blue control signal C-BL-B2 to the blue driving chip, so that the blue driving chip may supply power to a group of backlight lamps (i.e., a backlight blue lamp group) according to the corresponding power supply parameters, so as to reduce the brightness parameters of the backlight red lamp group.

Because the electronic device determines the first adjustment parameter of each color according to each gray-scale data set including the gray-scale value of the pixel point corresponding to each color in the picture to be displayed, that is, the first adjustment parameter of each color is related to the gray-scale value of the pixel point of each color, when the brightness of some colors in the picture to be displayed is higher, the first adjustment parameter of some colors can be different from the first adjustment parameters of other colors, but not the adjustment parameters of all colors are the same, therefore, after the brightness parameters of different groups of backlight lamps of different colors are adjusted according to the different first adjustment parameters by the electronic device, the brightness of some colors is reduced less, so that the image quality of the picture to be displayed is reduced less, and the cruising ability of the electronic device is improved, and the display effect of the electronic device is improved.

It can be understood that the electronic device can combine the gray-scale data set of the frame to be displayed to decompose the brightness of the backlight and control the brightness parameters of the backlight (i.e. red backlight, green backlight and blue backlight) respectively, so that the image quality can be reduced under the same power-saving effect condition compared with the CABC function in the related art.

And moreover, the electronic equipment can respectively control the groups of backlight lamps with different colors, so that the number of the backlight brightness adjustable by the electronic equipment can be increased, and the flexibility of the backlight brightness adjustment of the electronic equipment is improved.

Of course, in order to further improve the image quality of the to-be-displayed image, the electronic device may also display the to-be-displayed image according to a higher display parameter, which will be described below by way of example.

In some embodiments of the present application, as shown in fig. 5 in conjunction with fig. 1, after the step 101, the display control method provided in the embodiment of the present application may further include the following steps 301 to 303.

Step 301, the electronic device determines N third adjustment parameters according to the N gray-scale data sets.

It should be noted that, with respect to the execution sequence of step 301 and step 103, embodiments of the present application are not limited herein. In one example, the electronic device may perform step 301 first and then step 103; in another example, the electronic device may perform step 103 first and then step 301; in yet another example, the electronic device may perform step 103 while performing step 301. In fig. 5, the electronic device performs step 103 first, and then performs step 301.

In the embodiment of the present application, each of the N third adjustment parameters is an adjustment parameter corresponding to one color of a gray-scale data set.

In the embodiment of the present application, for each of the N third adjustment parameters, one third adjustment parameter is used to adjust a gray scale value of each pixel point of one color in the image to be displayed.

In some embodiments of the present application, for each of the N third adjustment parameters, one third adjustment parameter may specifically be a gray-scale pixel Gain parameter pixel-Gain, one third adjustment parameter may be an adjustment percentage, one third adjustment parameter may be different from other adjustment parameters, and one third adjustment parameter may be the same as a corresponding one of the first adjustment parameters. Wherein, the other adjustment parameters may be: of the N third adjustment parameters, adjustment parameters other than the one third adjustment parameter are used.

It should be noted that "a third adjustment parameter is the same as a corresponding first adjustment parameter" may be understood as: the one third adjustment parameter determined from the same gray scale data set may be the same as the one first adjustment parameter.

In some embodiments of the present application, the electronic device may determine one target value according to the gray-scale value of each pixel in each gray-scale data set, and then determine one third adjustment parameter corresponding to the one target value to determine N third adjustment parameters. Wherein the target value may be any one of the following: the gray scale value average (e.g., the first gray scale value in the embodiment described below), the gray scale value variance value, and the gray scale median value, each target value may represent the gray scale value of a pixel corresponding to one color.

Optionally, for each of the N target values, the larger one target value, the smaller one third adjustment parameter the electronic device determines according to the one target value.

It can be understood that, the larger the gray-scale value of the pixel point corresponding to a certain color is, the larger the corresponding target value is, the more likely a certain color is to be the dominant color of the picture to be displayed, i.e. the vividness of the certain color is higher, and the higher the gray-scale value of the pixel point corresponding to the certain color may cause distortion of the picture to be displayed, so the electronic device may adopt a smaller third adjustment parameter to raise the gray-scale value of the pixel point corresponding to the certain color; the smaller the gray-scale value of the pixel point of a certain color is, the smaller the corresponding target value is, the more likely the certain color is the auxiliary tone of the picture to be displayed, namely the brightness degree of the certain color is lower, the gray-scale value of the pixel point of the certain color is adjusted down, so that the picture to be displayed is not distorted, the electronic equipment can adopt a larger third adjustment parameter, the gray-scale value of the pixel point of the certain color is adjusted up, the picture to be displayed is not distorted, and the electronic equipment can adopt the larger third adjustment parameter, so that the gray-scale value of the pixel point of the certain color is adjusted up.

Optionally, in combination with fig. 2, the electronic device may determine, by the red gray scale data analysis module of the content analysis module, a target value according to D0-R in the red gray scale data temporary storage unit, and determine a third adjustment parameter corresponding to the one target value, and determine, by the green gray scale data analysis module of the content analysis module, another target value according to D0-G in the green gray scale data temporary storage unit, and determine, by the blue gray scale data analysis module of the content analysis module, another third adjustment parameter corresponding to the another target value, and determine, by the blue gray scale data analysis module, another target value according to D0-B in the blue gray scale data temporary storage unit, and determine yet another third adjustment parameter corresponding to the yet another target value.

It should be noted that, for the description of determining the N third adjustment parameters according to the N gray-scale data sets by the electronic device, reference may be made to the specific description of determining the N first adjustment parameters by the electronic device according to the N gray-scale data sets, which is not repeated herein in the embodiments of the present application.

Illustratively, in combination with fig. 2, after the communication module of the content analysis module receives the second adjustment parameter, the red gray scale data analysis unit of the content analysis module may determine a third adjustment parameter, for example, a red gray scale pixel Gain parameter pixel-Gain-R, according to a gray scale data set (for example, a gray scale data set including a gray scale value of each pixel of red) and the second adjustment parameter, the green gray scale data analysis unit of the content analysis module may determine another third adjustment parameter, for example, a green gray scale pixel Gain parameter pixel-Gain-G, according to another gray scale data set (for example, a gray scale data set including a gray scale value of each pixel of blue) and the second adjustment parameter, and the blue gray scale data analysis unit of the content analysis module may determine another third adjustment parameter, for example, a blue gray scale pixel Gain parameter pixel-Gain-R, according to another gray scale data set (for example, a gray scale data set including a gray scale value of each pixel of blue), so that the blue gray scale pixel Gain-Gain unit of the content analysis module may transmit the blue gray scale pixel Gain parameter pixel Gain-Gain parameter pixel-Gain-G to the blue gray scale unit, and the Gain unit may transmit the blue scale Gain parameter Gain-G to the blue gray scale unit.

Step 302, the electronic device respectively adjusts up the gray-scale value of each pixel point in the corresponding gray-scale data set according to each third adjustment parameter.

In some embodiments of the present application, for each third adjustment parameter of the N third adjustment parameters, the electronic device may multiply one third adjustment parameter with a corresponding one of the gray-scale data sets to obtain a gray-scale adjustment matrix, and then add the one gray-scale adjustment matrix and the one of the gray-scale data sets to increase the gray-scale value of each pixel in the one of the gray-scale data sets.

Optionally, referring to fig. 2, the red gray pixel Gain unit may sort the red gray pixel Gain parameter pixel-Gain-R, and send the sorted red gray pixel Gain parameter pixel-Gain-R to the red gray data temporary storage unit, so that the red gray data temporary storage unit may process D0-R in the red gray data temporary storage unit according to the red gray pixel Gain parameter pixel-Gain-R to form a new red gray pixel data set D2-R; the green gray pixel Gain unit can sort the green gray pixel Gain parameters pixel-Gain-G and send the sorted green gray pixel Gain parameters pixel-Gain-G to the green gray data temporary storage unit, so that the green gray data temporary storage unit can process D0-G in the green gray data temporary storage unit according to the green gray pixel Gain parameters pixel-Gain-G to form a new green gray pixel data set D2-G; and the blue gray pixel Gain unit can sort the blue gray pixel Gain parameter pixel-Gain-B and send the sorted blue gray pixel Gain parameter pixel-Gain-B to the blue gray data temporary storage unit, so that the blue gray data temporary storage unit can process the D0-B in the blue gray data temporary storage unit according to the blue gray pixel Gain parameter pixel-Gain-B to form a new blue gray pixel data set D2-B.

Step 303, when the brightness parameters of the N groups of backlight lamps are adjusted down according to the N first adjustment parameters, the electronic device increases the N gray-scale data sets according to the third adjustment parameters, and displays the to-be-displayed picture.

It can be understood that the display effect of the picture to be displayed is as follows: and the display effect corresponding to the N groups of backlight lamps after the brightness parameters are reduced and the display effect corresponding to the N gray-scale data sets after the brightness parameters are increased are overlapped.

In some embodiments of the present application, the electronic device may perform the synthesis processing according to the N adjusted gray-scale data sets to obtain a new data set, so that the electronic device may display the to-be-displayed screen according to the new data set.

Optionally, in combination with fig. 2, the communication unit of the content analysis module may combine D2-R, D-G and D2-B to form a new data set, and send the new data set to the communication unit of the GRAM module, so that the communication unit of the GRAM module may send the new data set to the resource output Source Out module, and further, the Source Out module may convert the new data set into an analog signal, and send the analog signal to the liquid crystal panel to display a screen to be displayed.

Therefore, the electronic device can determine N third adjustment parameters of N colors according to the N gray-scale data sets, and adjust up the gray-scale value of each pixel point in the gray-scale data set corresponding to each color according to the third adjustment parameter corresponding to each color, so that when the electronic device can display the to-be-displayed picture according to the adjusted gray-scale data set corresponding to each color, the picture effect of the to-be-displayed picture can be overlapped with the light effect of each group of backlight lamps with the brightness parameter adjusted down, so as to obtain a display effect similar to the original effect of the to-be-displayed picture, and the cruising ability of the electronic device can be improved, and the display effect of the electronic device can be improved.
