[0075] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0076] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0077] FIG1 is a schematic structural diagram of a display device according to an embodiment of the present application. The display device 10 may include a control component 11 and a display panel 12 . The control component 11 is connected to the display panel 12 , and the control component 11 may control the display panel 12 .

[0078] Specifically, the control component 11 may send a signal to the display panel 12 to control the display panel 12 to display an image. The control component 11 may include a timing controller (TCON).

[0079] Because some electronic components in the display panel 12 may be affected by various factors during the display process, the electrical properties of these electronic components may change, which in turn leads to poor display effects of the display panel 12. In this regard, in one method, the sub-pixels in the display panel can be sensed to obtain a compensation parameter (the compensation parameter can be called a compensation value K), and the sub-pixels can be compensated based on the compensation parameter. The change in K can represent the change in the electron mobility of the thin film transistor (TFT) in the organic light-emitting diode (OLED). Specifically, K is inversely proportional to the electron mobility and is affected by temperature, light, etc.

[0080] For example, please refer to Figure 2, which is a schematic diagram of the structure of a compensation pixel circuit. The pixel circuit may include: thin film transistor T1, thin film transistor T2 and thin film transistor T3, storage capacitor C1, organic light emitting diode, data line and sensing line. Among them, VDD can provide operating current for OLED. OLED is a current-type device. When current flows into OLED, it will be accompanied by temperature generation. As the lighting time increases, the temperature of the display panel will also rise. The increase in temperature will cause the voltage value detected by the sensing line end at the same voltage to differ. A compensation calculation formula for an OLED display panel is:

[0081] Where Vgs is the gate-source voltage of T1, Vth is the threshold voltage of T1, Vs is the voltage detected at the sensing line, and a is a constant. According to the compensation calculation formula above, as the temperature rises, Vs increases, thereby reducing the compensation K value and, consequently, Vgs.

[0082] Figure 3 is a schematic diagram of a compensation method. Please refer to Figure 3. The control component can sense the compensation parameters of a row of sub-pixels in each frame and perform compensation based on the compensation parameters. In the scheme shown in Figure 3, the control component senses each color in sequence according to a pre-ordered sequence. Specifically, when sensing the red sub-pixels, the red sub-pixels R of each row can be sensed in each frame, and the corresponding compensation parameters can be obtained for compensation. This process continues until the sensing of each row of red sub-pixels R in the display area is completed. After that, the sensing of the green sub-pixels G can be started. By analogy, the sub-pixels of each color in each frame in the display area can be sensed and compensated. It should be noted that the control component can add a specific waveform to the non-display area of ​​each frame to sense the compensation parameters of a row of sub-pixels, so as to avoid the compensation process affecting the normal display.

[0083] In this way, the frequency of compensation for sub-pixels of each color is the same. The time for sensing sub-pixels of one color in the display area is one frame length × the number of rows of sub-pixels in the display area. One frame length can be equal to 1 / frame rate, and the time for sensing sub-pixels of all colors in the display area is n × one frame length × the number of rows of sub-pixels in the display area, where n is the number of colors of the sub-pixels. For example, there are four colors of sub-pixels (such as red, green, blue, and white) in the display area, the number of rows of sub-pixels is 1080, and the frame rate is 60 Hz. The time for sensing sub-pixels of all colors in the display area is: 4 × (1 / 60) × 1080 = 72 seconds. The entire sensing cycle is relatively long, and the sensing frequency for sub-pixels of each color is consistent.

[0084] However, the applicant has found that in some display scenarios, the picture displayed by the display area may contain more of a certain color and have a higher brightness. For example, in a picture showing a forest, the area occupied by green may be larger than the areas occupied by other colors, and the brightness of the green area may be greater than the brightness of the areas of other colors. If the above method is used, the frequency of sensing and compensating the green sub-pixel is consistent with the frequency of sensing and compensating the sub-pixels of other colors. It can be seen that the flexibility of this compensation method is poor and the compensation effect may be poor.

[0085] FIG4 is a schematic diagram of a control component of a display panel provided in an embodiment of the present application, and FIG5 is a schematic diagram of a control flow of the control component shown in FIG4 . Referring to FIG4 and FIG5 , the control component 40 can be used to control the display panel. The control component 40 is used to:

[0086] Get the n-1th sensing cycle T n-1 In the display area aa of the display panel 50, the brightness parameters of the sub-pixels of multiple colors are positively correlated with the sub-pixel parameters of the sub-pixels of any color in the multiple colors during the sensing period. The sub-pixel parameters include the number of illuminated sub-pixels and at least one of the grayscale values ​​of the illuminated sub-pixels. The sensing period includes the duration of multiple frames of the display panel 50 during display. n is an integer greater than or equal to 1.

[0087] Determines a target color based on the brightness parameters of multiple colors.

[0088] In the nth sensing period T n In the embodiment, target compensation parameters of the sub-pixels of the target color are obtained, and the sub-pixels of the target color are compensated based on the target compensation parameters.

[0089] The sensing and compensation methods of the subsequent sensing cycles can refer to the n-1th sensing cycle T shown in FIG. 5 . n-1 And the n+1th sensing period T n+1 , the embodiments of this application will not be described in detail here.

[0090] To sum up, the control component provided in the embodiment of the present application obtains the brightness parameters of sub-pixels of various colors in the previous sensing cycle and determines the target color based on the brightness parameters. Thereafter, the target compensation parameters of the sub-pixels of the target color can be obtained in the current sensing cycle, and the sub-pixels of the target color can be compensated based on the target compensation parameters, rather than sensing the sub-pixels of each color based on a preset order. In this way, the sub-pixels can be compensated flexibly, which solves the problem of low flexibility of the compensation method of the control component in the related art and achieves the effect of improving the flexibility of the compensation method.

[0091] It should be noted that the multiple sub-pixels of different colors included in the display area can emit light of different colors when lit. Depending on the display screen, different sub-pixels will be lit, and the above brightness parameters can be parameters determined based on the lit sub-pixels.

[0092] FIG6 is another control flow diagram of the control component shown in FIG4 . Please refer to FIG4 and FIG6 . The control component 40 is further used for:

[0093] In the n-1th sensing cycle T n-1In the embodiment of the present invention, a first compensation parameter of a first color y1 among the multiple colors is obtained, and the sub-pixel of the first color y1 is compensated based on the first compensation parameter.

[0094] In the n+1th sensing period T n+1 In the embodiment of the present invention, a second compensation parameter of a second color y2 among the multiple colors is obtained, and the sub-pixel of the second color y2 is compensated based on the second compensation parameter.

[0095] Among them, the n-1th sensing period T n-1 And the n+1th sensing period T n+1 , which can be called a normal sensing period, and the n-1th sensing period T n-1 And the n+1th sensing period T n+1 The nth sensing period T between n , which can be called the target sensing cycle. In the conventional sensing cycle, each color sub-pixel can be sensed in turn and compensated accordingly. In the target sensing cycle, the sub-pixel of the target color can be sensed and the sub-pixel of the target color can be compensated based on the compensation parameters obtained by sensing. The target color is the target color according to the n-1th sensing cycle T n-1 The first color y1 is the color of any one of the multiple color sub-pixels in the display area of ​​the display panel, and the second color y2 is the color of another sub-pixel other than the first color y1 among the multiple color sub-pixels in the display area of ​​the display panel.

[0096] In this manner, the control component can sequentially sense and compensate for the sub-pixels of each color through a regular sensing cycle, and sense and compensate for the sub-pixels of the target color through a target sensing cycle between the regular sensing cycles, thereby increasing the compensation frequency of the sub-pixels of the target color and improving the compensation effect. In this way, the sub-pixels in the display panel are sensed and compensated alternately through the regular sensing cycle and the target sensing cycle. While ensuring that sub-pixels of various colors are compensated, the compensation frequency of the sub-pixels of a particular target color can be increased. Furthermore, since the target color is determined based on the brightness parameter, the compensation effect of this compensation method can be improved.

[0097] The sensing and compensation methods of the subsequent sensing cycles can refer to the n-1th sensing cycle T shown in FIG6. n-1 , the n+1th sensing period T n+1 And the n+1th sensing period T n+1 , the embodiments of this application will not be described in detail here.

[0098] In an exemplary embodiment, the target color is the color with the largest brightness parameter among the multiple colors. Alternatively, the target color is one or more colors among the multiple colors whose brightness parameter is greater than the brightness parameter threshold. That is, the control component can determine one or more colors with higher brightness among the multiple colors of the display panel as the target color. The sub-pixels of the color with higher brightness are also more obvious sub-pixels in the human eye. The control component provided in the embodiment of the present application increases the frequency of sensing and compensation of the sub-pixels of the target color with higher brightness, thereby improving the display effect of the sub-pixels of the target color with higher brightness. Since these sub-pixels are more prominent in the human eye, the user's display effect and viewing experience can be improved.

[0099] It should be noted that the control component may also determine the target color in various ways. For example, the control component may determine any one or more colors except the color with the smallest brightness parameter as the target color.

[0100] In an embodiment of the present application, the brightness parameter of a sub-pixel of any color among a plurality of colors is positively correlated with the sub-pixel parameter of the sub-pixel of any color in the sensing period. The sub-pixel parameter may include at least one of the number of lit sub-pixels and the grayscale value of the lit sub-pixel. That is, for a sub-pixel of a certain color, the greater the number of lit sub-pixels of the certain color, the greater the brightness parameter, and the greater the grayscale value of the lit sub-pixel of the certain color, the greater the brightness parameter.

[0101] In some embodiments, there may be a brightness parameter for determining a portion or all of the display area. For this, the brightness parameter of a sub-pixel of a first color among multiple colors in a specified area may satisfy: M=d*y;

[0102] M is the brightness parameter of the first color sub-pixel in the specified area, d is the number of the first color sub-pixels in the specified area, and y is the sum of the grayscale values ​​of the first color sub-pixels lit in the specified area. The specified area may be part of or all of the display area of ​​the display panel.

[0103] Exemplarily, the designated area is the entire area of ​​the display area, the first color is red, the number of red sub-pixels lit in the display area is 100, and the sum of the grayscale values ​​of these 100 red sub-pixels is 1000, then the brightness parameter M of the designated area is 100*1000=100000.

[0104] This method of determining the brightness parameter can expand the influence of the grayscale value and quantity on the brightness parameter, making it easier to distinguish the brightness parameters of sub-pixels of different colors.

[0105] When the control component provided in the embodiment of the present application performs sensing, the sensing period may be related to the number of rows of sub-pixels in the display area of ​​the display panel. In an exemplary embodiment, the display area includes x rows of sub-pixels, and the sensing period includes a*x frames in length, where a is an integer greater than or equal to 1.

[0106] That is, the duration of the sensing cycle can be an integer multiple of the product of the number of rows of sub-pixels in the display area and the duration of a frame, so as to ensure that at least sub-pixels of one color can be sensed in one sensing cycle.

[0107] When a is 1, in one sensing cycle, the control component can obtain the compensation parameters of sub-pixels of one color in all rows in the display area. When a is 2, in one sensing cycle, the control component can obtain the compensation parameters of sub-pixels of two colors in all rows in the display area.

[0108] In an exemplary embodiment, FIG7 is a schematic diagram of a sensing cycle in the control flow diagram shown in FIG6 , with reference to FIG4 and FIG7 , wherein the control component 40 may be used to:

[0109] In the nth sensing period T n The target compensation parameters of a row of sub-pixels of a target color in the display area are obtained in a frame, and the target compensation parameters of a row of sub-pixels of the target color are compensated based on the target compensation parameters of the row of sub-pixels.

[0110] The high-level region in FIG7 may indicate that the period is a non-display region within a frame when the display signal is transmitted (but does not limit the actual signal level), and the low-level region may indicate that the period is a display region within a frame when the display signal is transmitted (but does not limit the actual signal level). It can be seen that the control component 40 can obtain compensation parameters for a row of sub-pixels in the non-display region of each frame.

[0111] It should be noted that the display area of ​​a display panel may include multiple rows of pixels, each row of pixels may include multiple pixels, and each pixel may include multiple sub-pixels, and the number of rows of sub-pixels is equal to the number of rows of pixels. For example, for a display panel with a resolution of 1920×1080, the display area may include 1080 rows of pixels, a row of pixels may include 1920 pixels, each pixel may include 3 or 4 sub-pixels, and the number of rows of sub-pixels is also 1080.

[0112] In the above embodiment, the control component can sense and compensate the display area as a whole area. However, in an exemplary embodiment, the display area of ​​the display panel may include multiple sub-display areas, each sub-display area includes multiple rows of sub-pixels, and the control component can sense and compensate these multiple sub-display areas.

[0113] FIG8 is a schematic diagram of a display area in an embodiment of the present application, and FIG9 is a schematic diagram of a sensing process provided by an embodiment of the present application. Referring to FIG8 and FIG9 , in an exemplary embodiment, the display area aa includes multiple sub-display areas saa. The control component is used to:

[0114] 1) Get the n-1th sensing cycle T n-1 , brightness parameters of multiple colors in each sub-display area in multiple sub-display areas.

[0115] The calculation method for the brightness parameter of any of the multiple sub-display areas can refer to the calculation method for the brightness parameter of the designated area provided in the above embodiment. The control component can treat a sub-display area as a designated area and calculate the brightness parameter of this sub-display area. That is, the brightness parameter of the sub-pixel of the first color among the multiple colors in the designated area can satisfy: M = d * y;

[0116] M is the brightness parameter of the first color sub-pixel in the sub-display area, d is the number of the first color sub-pixels lit in the sub-display area, and y is the sum of the grayscale values ​​of the first color sub-pixels lit in the specified area.

[0117] Of course, the brightness parameter of the sub-display area may also be determined by other calculation methods. For example, the brightness parameter of the sub-pixel of the first color among the multiple colors in the sub-display area may satisfy: M'=q*d'*y';

[0118] M' is the brightness parameter of the sub-pixel of the first color in the sub-display area, d' is the number of sub-pixels of the first color in the sub-display area, the sub-display area may be a partial area in the display area of ​​the display panel, y' is the sum of the grayscale values ​​of the sub-pixels of the first color lit in the sub-display area, and q is the weight parameter of the sub-display area. The weight parameter may be negatively correlated with the distance between the sub-display area and the center of the display area of ​​the display panel, that is, the farther the sub-display area is from the center of the display area, the smaller the weight parameter q is, and the closer the sub-display area is to the center of the display area, the larger the weight parameter q is. This is because the user's attention to the area near the center of the display area is greater than the attention to the edge area far from the center, and thus the weight parameter of the area near the center can be increased to increase the compensation frequency for this area.

[0119] Exemplarily, as shown in FIG8 , the distance between the first sub-display area aa1 and the center z of the display area is greater than the distance between the second sub-display area aa2 and the center z of the display area, then the weight parameter of the second sub-display area aa2 may be greater than the weight parameter of the first sub-display area aa1.

[0120] In addition, the control component can also be in the n-1th sensing cycle T n-1In the embodiment of the present invention, a first compensation parameter of the first color y1 is obtained, and the sub-pixel of the first color is compensated based on the first compensation parameter.

[0121] 2) Determine a sub-display area target color for each sub-display area saa in the plurality of sub-display areas. The sub-display area target color is a color having the largest brightness parameter in each sub-display area saa.

[0122] In this step, the control component can determine a sub-display area target color for each sub-display area saa based on the brightness parameters of the various colors in each sub-display area saa determined in the above manner. The sub-display area target color can be the color with the maximum brightness parameter in each sub-display area saa. For example, in a first sub-display area, the brightness parameter of the red sub-pixel is 10,000, the brightness parameter of the green sub-pixel is 12,000, the brightness parameter of the blue sub-pixel is 15,000, and the brightness parameter of the white sub-pixel is 20,000. The control component can determine white as the sub-display area target color for the first sub-display area.

[0123] The control component can be in the n-1th sensing cycle T n-1 This step is performed after the brightness parameters of multiple colors in each of the multiple sub-display areas are obtained.

[0124] 3) In the nth sensing cycle, sub-compensation parameters of the sub-pixels of the sub-display area target color in each sub-display area are obtained, and the sub-pixels of the sub-display area target color in each sub-display area are compensated based on the sub-compensation parameters.

[0125] After determining the sub-display target color for each sub-display area saa, the control component can obtain the sub-compensation parameters for the sub-pixels of the sub-display target color in each sub-display area saa during the nth sensing cycle and perform compensation accordingly. Because the display content of each sub-display area may vary, this approach allows for independent sensing and compensation of each sub-display, further improving the compensation effect on the display panel.

[0126] It should be noted that in one sensing cycle, the control component can sense and compensate for a sub-pixel of one color in the entire display area at least once, and these multiple sub-display areas can be multiple areas divided into the display area. Therefore, the control component can sense and compensate for these multiple sub-display areas separately in one sensing cycle.

[0127] In addition, in subsequent sensing cycles, the control component may refer to the n-1th sensing cycle and the nth sensing cycle, which will not be described in detail in the embodiment of the present application.

[0128] The control component provided in the embodiment of the present application can also sense and compensate for multiple sub-display areas in other ways. For example, FIG10 is a schematic diagram of another display area in the embodiment of the present application, and FIG11 is a schematic diagram of another sensing process provided in the embodiment of the present application. Referring to FIG10 and FIG11, in an exemplary embodiment, the display area aa includes multiple sub-display areas saa, and each sub-display area saa includes multiple rows of sub-pixels;

[0129] Control components are used to:

[0130] 1) Get the n-1th sensing cycle T n-1 , brightness parameters of multiple colors in each sub-display area in multiple sub-display areas.

[0131] The sub-display areas can each include the same number of rows of sub-pixels, thereby reducing the complexity of the control component's sensing and compensation methods for each sub-display area. For example, if there are 1000 rows of sub-pixels in the display area and there are five sub-display areas, each of the five sub-display areas can have 200 rows of sub-pixels.

[0132] Of course, the number of rows of sub-pixels included in the multiple sub-display areas may also be different, and the embodiment of the present application does not limit this.

[0133] The manner in which the control component obtains the brightness parameter can be referred to the above embodiment, and the embodiments of the present application will not be described in detail here.

[0134] 2) Determine a first color sub-display area among a plurality of sub-display areas.

[0135] After determining the brightness parameter of each color in each sub-display area, the control component can determine a first color sub-display area among the multiple sub-display areas. The first color sub-display area is the sub-display area in which the brightness parameter of the sub-pixel of the first color is the largest among the multiple sub-display areas. This step can be performed in the n-1th sensing period T n-1 In the example, the control component obtains the brightness parameters of multiple colors in each sub-display area and then executes.

[0136] The determination process may specifically include:

[0137] 2.1. The control component determines the brightness parameters of the sub-pixels of each color in all sub-display areas;

[0138] The control component can determine the brightness parameter of the sub-pixel of each color in each sub-display area, so that one sub-display area can have brightness parameters of multiple colors.

[0139] For example, if the display area has sub-pixels of four colors: red, green, blue, and white, the control component can determine the brightness parameters of the four colors corresponding to each sub-display area.

[0140] In a specific example, the display area may include a first sub-display area, a second sub-display area, a third sub-display area, a fourth sub-display area, and a fifth sub-display area. The brightness parameters of the sub-pixels of each color in these sub-display areas can be referred to Table 1:

[0141] Table 1

[0142] The data recorded in Table 1 are brightness parameters. The control component can determine the sub-display area corresponding to the maximum brightness parameter of each color based on the brightness parameters shown in Table 1. For example, if the maximum brightness parameter of the red sub-pixel is 15000, then the maximum brightness parameter of the red sub-pixel corresponds to the fifth sub-display area. If the maximum brightness parameter of the green sub-pixel is 24000, then the maximum brightness parameter of the green sub-pixel corresponds to the fourth sub-display area. Similarly, the sub-display area with the maximum brightness parameter of each color sub-pixel can be determined.

[0143] 2.2. The control component determines a first color sub-display area based on the brightness parameters of the sub-pixels of each color in the sub-display area;

[0144] The control component may determine the sub-display area having the largest brightness parameter of the first color as the first color sub-display area. Taking the parameters shown in Table 1 as an example, if the first color is red, the first color sub-display area is the red sub-display area. The control component may determine the fifth sub-display area having the largest brightness parameter of the red sub-pixel as the red sub-display area.

[0145] 3) In the nth sensing cycle T n In the embodiment, sub-compensation parameters of the sub-pixels of the first color in the first color sub-display area are obtained, and the sub-pixels of the first color in the first color sub-display area are compensated based on the sub-compensation parameters of the sub-pixels of the first color.

[0146] After determining the first color sub-display area, the control component can obtain sub-compensation parameters for the first color sub-pixels in the first color sub-display area during the nth sensing cycle, and compensate the first color sub-pixels in the first color sub-display area based on the sub-compensation parameters of the first color sub-pixels. The sub-compensation parameters are similar to the compensation parameters described above. The first color sub-display area has several rows of sub-pixels, and the control component can sense and obtain the compensation parameters for these rows of sub-pixels over the duration of several frames and perform compensation accordingly.

[0147] In this manner, each color in the display area of ​​the display panel can be a target color, but for each color, the control component can select one or more sub-display areas from the multiple sub-display areas for sensing and compensation.

[0148] 4) Determine a second color sub-display area among the plurality of sub-display areas.

[0149] The control component can refer to the above-described step of determining the first color sub-display area to determine a second color sub-display area among the multiple sub-display areas. The second color sub-display area is the sub-display area in which the brightness parameter of the sub-pixels of the second color is the largest among the multiple sub-display areas. For example, using the data shown in Table 1, the second color can be blue, and the second color sub-display area is the blue sub-display area. The control component can determine the third sub-display area in which the brightness parameter of the blue sub-pixels is the largest as the red sub-display area.

[0150] 5) In the nth sensing cycle T n In the embodiment, sub-compensation parameters of the sub-pixels of the second color in the second color sub-display area are obtained, and the sub-pixels of the first color in the second color sub-display area are compensated based on the sub-compensation parameters of the sub-pixels of the second color.

[0151] After determining the second color sub-display area, the control component can obtain sub-compensation parameters for the second color sub-pixels in the second color sub-display area during the nth sensing cycle, and compensate the second color sub-pixels in the second color sub-display area based on the sub-compensation parameters of the second color sub-pixels. The sub-compensation parameters are similar to the compensation parameters described above. The second color sub-display area has several rows of sub-pixels, and the control component can sense and obtain the compensation parameters for these rows of sub-pixels over the duration of several frames and perform compensation accordingly.

[0152] In an exemplary embodiment, since the brightness parameter of the sub-pixels of multiple colors in one sub-display area is the maximum brightness parameter among the brightness parameters of the sub-pixels of the multiple colors, the second color sub-display area and the first color sub-display area may be the same sub-display area (of course, the second color sub-display area and the first color sub-display area may also be different sub-display areas). For example, please refer to Table 2:

[0153] Table 2

[0154] Table 2 is another table of brightness parameters for each sub-display area in an embodiment of the present application. As can be seen from Table 2, the brightness parameter of the blue sub-pixel in the third sub-display area is the maximum brightness parameter among the brightness parameters of the blue sub-pixels in each sub-display area, and the brightness parameter of the white sub-pixel in the third sub-display area is also the maximum brightness parameter among the brightness parameters of the white sub-pixels in each sub-display area. Therefore, the third sub-display area can be a blue sub-display area and a white sub-display area. In this case, the control component can obtain the sub-compensation parameter of the blue sub-pixel and the sub-compensation parameter of the white sub-bin in the third sub-display area during the nth sensing cycle, and compensate the blue sub-pixels and white sub-pixels in the third sub-display area.

[0155] Of course, it is also possible that a sub-display area may be a sub-display area with multiple colors. The control component can sense and compensate in this way, and the embodiments of the present application will not be described in detail here.

[0156] It should be noted that when the number of sub-display areas is greater than the number of types of colors of sub-pixels in the display area of ​​the display panel, there may be one or more sub-display areas whose brightness parameters of sub-pixels of various colors are not the maximum brightness parameters. In this case, the control component can also execute subsequent steps.

[0157] 6) In the nth sensing cycle, sub-compensation parameters of sub-pixels of a preset color in at least one low-brightness sub-display area are obtained, and sub-pixels of the preset color are compensated based on the sub-compensation parameters of the sub-pixels of the preset color.

[0158] In an exemplary embodiment, the multiple sub-display areas within the display region of the display panel include at least one low-brightness sub-display area, and the brightness parameters of the sub-pixels of multiple colors in the low-brightness sub-display area are not the maximum brightness parameters. In this case, the control component may obtain the sub-compensation parameters of the sub-pixels of a preset color in the at least one low-brightness sub-display area during the nth sensing cycle, and compensate the sub-pixels of the preset color based on the sub-compensation parameters of the sub-pixels of the preset color.

[0159] For example, taking the data shown in Table 2 as an example, in the second sub-display area, the brightness parameter of the red sub-pixel, the brightness parameter of the blue sub-pixel, the brightness parameter of the green sub-pixel, and the brightness parameter of the white sub-pixel are not the maximum brightness parameters, then the second sub-display area is a low-brightness sub-display area, and the control component can sense and compensate for the sub-pixels of the preset color in the second sub-display area, which is the low-brightness sub-display area, based on a preset color order.

[0160] Of course, in some cases, there may not be a low-brightness sub-display area in the display area. For example, when the number of sub-display areas is less than or equal to the number of types of colors of sub-pixels in the display area, there may not be a low-brightness sub-display area in the display area. The embodiments of the present application do not limit this.

[0161] The control method of the subsequent sensing cycles can refer to the n-1th sensing cycle T n-1 And the nth sensing period T n , the embodiments of this application will not be described again here.

[0162] The control component provided in the embodiment of the present application can also determine the target color through other methods. FIG12 is a schematic diagram of another sensing process provided in the embodiment of the present application. Please refer to FIG12 . The control component is also used to:

[0163] 1) Determine whether the brightness parameters of the multiple colors include a brightness parameter of the target color that is greater than a brightness parameter threshold.

[0164] After obtaining the brightness parameters of the sub-pixels of multiple colors in the display area of ​​the display panel in the n-1th sensing cycle, the control component can determine whether the brightness parameters of the multiple colors include the brightness parameter of the target color that is greater than the brightness parameter threshold. That is, the control component can determine the color whose brightness parameters of the sub-pixels of multiple colors are greater than the brightness parameter threshold as the target color.

[0165] For example, if in the display area, the brightness parameter of the red sub-pixel is 10000, the brightness parameter of the green sub-pixel is 20000, the brightness parameter of the blue sub-pixel is 30000, the brightness parameter of the white sub-pixel is 40000, and the brightness parameter threshold is 25000, then the control component can determine the blue corresponding to the blue sub-pixel with a brightness greater than 25000 and the white corresponding to the white sub-pixel as the target color. Of course, there is also a situation where the brightness parameters of the sub-pixels of all colors are less than or equal to the brightness parameter threshold. In this case, there is no target color, and the embodiments of the present application are not limited to this.

[0166] In addition, the control component may obtain a first compensation parameter of a first color among the multiple colors in the (n-1)th sensing cycle, and compensate the sub-pixel of the first color based on the first compensation parameter.

[0167] 2) In response to a brightness parameter of a target color greater than a brightness parameter threshold, in the nth sensing period T n In the embodiment, a target compensation parameter of a sub-pixel of a target color is obtained, and the sub-pixel of the target color is compensated based on the target compensation parameter.

[0168] When the brightness parameter of only one sub-pixel of a target color is greater than the brightness parameter threshold, the control component can obtain the target compensation parameter of the sub-pixel of the target color in the nth sensing cycle, and compensate the sub-pixel of the target color based on the target compensation parameter.

[0169] 3) In response to the brightness parameters of s target colors being greater than the brightness parameter threshold, in the nth sensing period T n In the embodiment, target compensation parameters of s sub-pixels of target color in a first sub-display area among the s sub-display areas are obtained, and compensation is performed on the s sub-pixels of target color in the first sub-display area based on the target compensation parameters.

[0170] Please refer to Figures 12 and 10. When the brightness parameters of sub-pixels of s colors are greater than the brightness parameter threshold, the display area may include s sub-display areas, and each sub-display area includes the same number of rows of sub-pixels. Accordingly, the control component can obtain target compensation parameters for the s sub-pixels of the target color in the first sub-display area of ​​the s sub-display areas during the nth sensing cycle, and compensate the s sub-pixels of the target color in the first sub-display area based on the target compensation parameters. Since compensation is performed on sub-pixels of s colors, the control component can sense and compensate for 1 / s sub-display areas of the display area during a single sensing cycle.

[0171] Furthermore, in the (n+1)th sensing cycle, the control component obtains a second compensation parameter for a second color among the plurality of colors and compensates the sub-pixels of the second color based on the second compensation parameter. Thus, in the (n+1)th sensing cycle, the control component can sequentially sense and compensate the sub-pixels of one color in each sensing cycle according to a pre-set order.

[0172] 4) In the n+2th sensing cycle T n+2 In the embodiment, target compensation parameters of s sub-pixels of target color in a second sub-display area among the s sub-display areas are obtained, and compensation is performed on the s sub-pixels of target color in the second sub-display area based on the target compensation parameters.

[0173] That is, the control component can sense and compensate the s sub-pixels of the target color in the s sub-display areas in s sensing cycles respectively.

[0174] The sensing period of obtaining the target compensation parameters of the s sub-pixels of the target color in one of the s sub-display areas and compensating the s sub-pixels of the target color in the sub-display area based on the target compensation parameters can be called a target sensing period, and the sensing period of sensing and compensating the sub-pixels of one color in each sensing period in turn according to a preset order can be called a regular sensing period, and there can be at least one regular sensing period between any two adjacent target sensing periods.

[0175] In addition, when the brightness parameter of no sub-pixel of any color is greater than the brightness parameter threshold, the control component may continue to sense and compensate the sub-pixels of one color in each sensing cycle in a preset order.

[0176] To sum up, the control component provided in the embodiment of the present application obtains the brightness parameters of sub-pixels of various colors in the previous sensing cycle and determines the target color based on the brightness parameters. Thereafter, the target compensation parameters of the sub-pixels of the target color can be obtained in the current sensing cycle, and the sub-pixels of the target color can be compensated based on the target compensation parameters, rather than sensing the sub-pixels of each color based on a preset order. In this way, the sub-pixels can be compensated flexibly, which solves the problem of low flexibility of the compensation method of the control component in the related art and achieves the effect of improving the flexibility of the compensation method.

[0177] FIG13 is a flow chart of a method for controlling a display panel provided in an embodiment of the present application. The method can be used in a control component provided in the above embodiment to control a display panel. The method may include the following steps:

[0178] Step 1301: Obtain brightness parameters of sub-pixels of multiple colors in the display area of ​​the display panel in the n-1th sensing cycle, wherein the brightness parameters of the sub-pixels of any color among the multiple colors are positively correlated with the sub-pixel parameters of the sub-pixels of any color in the sensing cycle, and the sub-pixel parameters include at least one of the number of illuminated sub-pixels and the grayscale values ​​of the illuminated sub-pixels. The sensing cycle includes the duration of multiple frames of the display area.

[0179] Step 1302: Determine a target color based on brightness parameters of multiple colors.

[0180] Step 1303 : In the nth sensing cycle, obtain target compensation parameters of the sub-pixels of the target color, and compensate the sub-pixels of the target color based on the target compensation parameters.

[0181] To sum up, the display panel control method provided in the embodiment of the present application obtains the brightness parameters of sub-pixels of various colors in the previous sensing cycle and determines the target color based on the brightness parameters. Thereafter, the target compensation parameters of the sub-pixels of the target color can be obtained in the current sensing cycle, and the sub-pixels of the target color can be compensated based on the target compensation parameters, rather than sensing the sub-pixels of each color based on a preset order. In this way, the sub-pixels can be compensated flexibly, which solves the problem of low flexibility of the compensation method of the control component in the related art and achieves the effect of improving the flexibility of the compensation method.

[0182] Optionally, the above method further includes:

[0190] The compensation module 1430 is configured to obtain target compensation parameters of sub-pixels of a target color in an nth sensing cycle, and compensate the sub-pixels of the target color based on the target compensation parameters.

[0191] To sum up, the control component provided in the embodiment of the present application obtains the brightness parameters of sub-pixels of various colors in the previous sensing cycle and determines the target color based on the brightness parameters. Thereafter, the target compensation parameters of the sub-pixels of the target color can be obtained in the current sensing cycle, and the sub-pixels of the target color can be compensated based on the target compensation parameters, rather than sensing the sub-pixels of each color based on a preset order. In this way, the sub-pixels can be compensated flexibly, which solves the problem of low flexibility of the compensation method of the control component in the related art and achieves the effect of improving the flexibility of the compensation method.
