[0030] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] In order to better understand the embodiments of the present application, the relevant technologies are first introduced below.

[0032] The display power consumption of the display screen can be reduced by grayscale domain, that is, reducing the grayscale of part of the display content, that is, reducing the grayscale of non-critical display content. Since the grayscale of part of the display content is reduced by adding a mask, part of the grayscale is lost, and the grayscale of the display screen may be lost, resulting in poor display effect.

[0033] Therefore, it is very important to reduce display power consumption while ensuring display effect.

[0034] Fig. 1 is a flow chart of a data display method provided by an embodiment of the present application. The data display method can be applied to the above-mentioned mobile terminal. As shown in Fig. 1, the data display method can include the following steps.

[0035] 101. Obtain data to be displayed.

[0036] In the case that there is data to be displayed, the mobile terminal may acquire the data to be displayed.

[0037] The mobile terminal may obtain the data to be displayed locally, from a network, or from other devices.

[0038] The data to be displayed may include one or more of text data, picture data, video data, etc.

[0039] 102. Determine a source voltage corresponding to each pixel in the display screen according to the data to be displayed.

[0040] Different data to be displayed may cause different voltages corresponding to pixels. Therefore, after the mobile terminal obtains the data to be displayed, it can determine the source voltage corresponding to each pixel in the display screen according to the data to be displayed, that is, determine the source voltage corresponding to each pixel in all pixels included in the display screen according to the data to be displayed.

[0041] The source voltage corresponding to the pixel is the voltage corresponding to the pixel directly determined according to the data to be displayed.

[0042] The display screen may include a plurality of pixels, a plurality of organic light emitting diodes (OLEDs), and a plurality of positive channel metal oxide semiconductors (PMOS) tubes. The plurality of PMOS tubes correspond one-to-one to the plurality of OLEDs, and the plurality of pixels correspond one-to-one to the plurality of OLEDs.

[0043] The PMOS tube can provide a driving current for the corresponding OLED, and the OLED can work based on the driving current provided by the corresponding PMOS tube.

[0044] The voltage corresponding to the pixel is the voltage of the gate of the PMOS tube corresponding to the pixel, that is, the input voltage of the gate of the PMOS tube.

[0045] 103. Determine a target voltage corresponding to each pixel point according to a source voltage corresponding to each pixel point.

[0046] The target voltage corresponding to each pixel is greater than or equal to the corresponding source voltage.

[0047] The mobile terminal can determine the target voltage corresponding to each pixel point according to the source voltage corresponding to each pixel point, that is, adjust the voltage corresponding to each pixel point from the source voltage to the target voltage, that is, increase the voltage corresponding to the pixel point from the source voltage to the target voltage, or keep it unchanged.

[0048] 104. Drive corresponding pixel points according to the target voltage corresponding to each pixel point, so that the display screen displays the data to be displayed.

[0049] After the mobile terminal determines the target voltage corresponding to each pixel, the corresponding pixel can be driven according to the target voltage corresponding to each pixel, so that the display screen displays the data to be displayed.

[0050] The mobile terminal can drive the corresponding PMOS tube to operate in the linear region according to the target voltage corresponding to each pixel point, so that the PMOS tube can provide a driving current for the corresponding OLED, and the OLED can operate based on the driving current provided by the corresponding PMOS tube to make the corresponding pixel point display the corresponding data in the data to be displayed.

[0051] In the data display method shown in FIG1 , the voltage corresponding to each pixel is inversely correlated with the current of the organic light emitting diode corresponding to each pixel, that is, the larger the voltage corresponding to each pixel, the smaller the current of the organic light emitting diode corresponding to each pixel. Since the voltage corresponding to some or all pixels is increased, the current of the organic light emitting diode corresponding to some or all pixels can be reduced. Since the display power consumption of the display screen is positively correlated with the current of the organic light emitting diode, the display power consumption of the display screen can be reduced. In addition, since the voltage corresponding to the pixel is adjusted, the smoothness of the picture can be guaranteed, and the display effect can be guaranteed while reducing the display power consumption.

[0052] Figure 2 FIG. 1 is a flow chart of another data display method provided by an embodiment of the present application. The data display method can be applied to a mobile terminal. Figure 2 As shown, the data display method may include the following steps.

[0053] 201. Obtain data to be displayed.

[0054] The detailed description of step 201 may refer to the description of step 101 .

[0055] 202. Determine a source voltage corresponding to each pixel in the display screen according to the data to be displayed.

[0056] The detailed description of step 202 may refer to the description of step 102 .

[0057] 203. Determine a voltage compensation coefficient corresponding to each pixel point according to the coefficient table.

[0058] Since the voltage corresponding to the pixel is inversely correlated with the current of the organic light-emitting diode corresponding to the pixel, and the display power consumption of the display screen is positively correlated with the current of the organic light-emitting diode, the voltage corresponding to the pixel is inversely correlated with the display power consumption of the display screen. In order to reduce the display power consumption of the display screen, the voltage corresponding to the pixel can be increased. The voltage corresponding to the pixel can be compensated by coefficient compensation so that the voltage corresponding to the pixel can be increased. Therefore, the mobile terminal can first determine the voltage compensation coefficient corresponding to each pixel.

[0059] The mobile terminal may store a coefficient table and determine the voltage compensation coefficient corresponding to each pixel point according to the coefficient table.

[0060] The coefficient table may include coefficients. The mobile terminal may determine the voltage compensation coefficient corresponding to each pixel point according to the coefficients included in the coefficient table.

[0061] The coefficients included in the coefficient table are voltage compensation coefficients determined in advance through testing or the like.

[0062] The coefficient table may also include a position, ie, position information. The mobile terminal may determine the voltage compensation coefficient corresponding to each pixel point according to the correspondence between the position and the coefficient in the coefficient table. The position included in the coefficient table is the position in the display screen.

[0063] Figure 3 This is a schematic diagram of segmenting a display screen provided in an embodiment of the present application. Figure 4 This is another schematic diagram of dividing a display screen provided in an embodiment of the present application. This application does not limit the division method of the display screen.

[0064] like Figure 3 and Figure 4 As shown, the display screen has 2*m division points in the X direction, namely X1, X2, X3, ..., Xm, Xm1, ..., X31, X21, and X11. The center line of the X direction can divide the display screen into two half screens along the X direction. The m division points X1, X2, X3, ..., Xm are located in one half screen, and the m division points Xm1, ..., X31, and X21 are located in the other half screen. The m division points in the two half screens are symmetrical relative to the center line of the X direction, that is, X1 and X11 are symmetrical relative to the center line of the X direction, X2 and X21 are symmetrical relative to the center line of the X direction, ..., Xm and Xm1 are symmetrical relative to the center line of the X direction. m is an integer greater than 1.

[0065] Similarly, the display screen has 2*n division points in the Y direction, namely Y1, Y2, Y3, ..., Yn, Yn1, ..., Y31, Y21, and Y11. The center line of the Y direction can divide the display screen into two half screens along the Y direction. The n division points Y1, Y2, Y3, ..., Yn are located in one half screen, and the n division points Yn1, ..., Y31, and Y21 are located in the other half screen. The n division points in the two half screens are symmetrical relative to the center line of the Y direction, that is, Y1 and Y11 are symmetrical relative to the center line of the Y direction, Y2 and Y21 are symmetrical relative to the center line of the Y direction, ..., Yn and Yn1 are symmetrical relative to the center line of the Y direction. n is an integer greater than 1.

[0066] The segmentation in the X direction and the Y direction can be equal interval segmentation or unequal interval segmentation, that is, the distances between adjacent segmentation points in the same direction can be equal or unequal.

[0067] The X direction may be the direction of the short side of the display screen, and the Y direction may be the direction of the long side of the display screen. The X direction may also be the direction of the long side of the display screen, and the Y direction may be the direction of the short side of the display screen.

[0068] The coefficient table can be shown in Table 1:

[0069] Location coefficient X_1 GX1 X_2 GX2 X_3 GX3 … … X_m G JZ X_m1 GXm1 … … X_31 GX31 X_21 GX21 X_11 GX11 Y_1 GY1 Y_2 GY2 Y_3 GY3 … … Y_n G JZ Y_n1 G JZ … … Y_31 GY31 Y_21 GY21 Y_11 GY11

[0070] Table 1

[0071] As shown in Table 1, the coefficient table may include the positions of 2*m segmentation points in the X direction, the coefficients in the X direction corresponding to the 2*m segmentation points, the positions of 2*n segmentation points in the Y direction, and the coefficients in the Y direction corresponding to the 2*n segmentation points.

[0072] It should be understood that Table 1 is an exemplary description of the coefficient table and does not limit the coefficient table.

[0073] The number of segmentation points in the X direction may be the same as or less than the number of pixels in the X direction. Similarly, the number of segmentation points in the Y direction may be the same as or less than the number of pixels in the Y direction.

[0074] Assume that the display screen includes K*L pixels, K is the pixel in the X direction, and L is the pixel in the Y direction. K and L are integers greater than 1. K can be equal to 2*m or less than 2*m. L can be equal to 2*n or less than 2*n.

[0075] It can be seen from Table 1 that the coefficients include not only the coefficients in the X direction, but also the coefficients in the Y direction. Therefore, each pixel point may correspond to two voltage compensation coefficients, one for the voltage compensation coefficient in the X direction, and the other for the voltage compensation coefficient in the Y direction.

[0076] Therefore, the mobile terminal can determine the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to each pixel point according to the coefficient table. The first voltage compensation coefficient is the voltage compensation coefficient of the first direction, and the second voltage compensation coefficient is the voltage compensation coefficient of the second direction, and the first direction is perpendicular to the second direction. The first direction can be the X direction, and the second direction can be the Y direction. Conversely, the first direction can also be the Y direction, and the second direction can also be the X direction.

[0077] The mobile terminal may have two methods for determining the voltage compensation coefficient corresponding to the pixel point: one method is a mirror compensation method, and the other method is a non-mirror compensation method.

[0078] The mobile terminal may have a mirror compensation component. The user may start or turn on the mirror compensation mode through the mirror compensation component, or may turn off the mirror compensation mode through the mirror compensation component.

[0079] When the mirror compensation mode is turned off, that is, the mirror compensation mode is not adopted, the mobile terminal can determine the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to each pixel point according to the coefficient table, that is, it is necessary to determine the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to each pixel point among all pixels based on the coefficients in the coefficient table, that is, the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to each pixel point are both determined according to the coefficients in the coefficient table.

[0080] When the mirror compensation method is not adopted, in the process of determining the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to each pixel point, all the coefficients in Table 1 will be used.

[0081] In the case where the mirror compensation method is not adopted, since the voltage compensation coefficient corresponding to each pixel is determined based on the coefficient in the coefficient table, and the coefficient in the coefficient table is determined in advance through testing and the like, the applicability of the voltage compensation coefficient corresponding to each pixel can be improved, thereby improving the accuracy of the target voltage corresponding to each pixel, so that the display power consumption can be better reduced.

[0082] When the mirror compensation mode is turned on, that is, the mirror compensation mode is adopted, the mobile terminal can determine the first voltage compensation coefficient corresponding to the first part of the pixels according to the coefficient table, and can determine the first voltage compensation coefficient corresponding to the remaining pixels according to the first voltage compensation coefficient corresponding to the first part of the pixels. Similarly, the mobile terminal can determine the second voltage compensation coefficient corresponding to the second part of the pixels according to the coefficient table, and can determine the second voltage compensation coefficient corresponding to the remaining pixels according to the second voltage compensation coefficient corresponding to the second part of the pixels. The first part of the pixels is different from the second part of the pixels.

[0083] The mobile terminal may first determine the voltage compensation coefficient in one direction corresponding to the pixel points in the half screen divided by the center line of the direction, and then determine the voltage compensation coefficient in the other direction corresponding to the pixel points in the other half screen divided by the center line of the direction according to the symmetry of the center line of the direction. Figure 3 and Figure 4 As shown, the mobile terminal may first determine the voltage compensation coefficient in the X direction corresponding to the pixel points of the upper half screen, and then determine the voltage compensation coefficient in the X direction corresponding to the pixel points of the lower half screen according to the voltage compensation coefficient in the X direction corresponding to the pixel points of the upper half screen. Similarly, the mobile terminal may first determine the voltage compensation coefficient in the Y direction corresponding to the pixel points of the left half screen, and then determine the voltage compensation coefficient in the Y direction corresponding to the pixel points of the right half screen according to the voltage compensation coefficient in the Y direction corresponding to the pixel points of the left half screen.

[0084] Specifically, in the case of adopting the mirror compensation method, the mobile terminal can determine the first voltage compensation coefficient corresponding to the first pixel point according to the coefficient table, can determine the first voltage compensation coefficient corresponding to the second pixel point as the first voltage compensation coefficient corresponding to the first pixel point, can determine the second voltage compensation coefficient corresponding to the third pixel point according to the coefficient table, and can determine the second voltage compensation coefficient corresponding to the fourth pixel point as the second voltage compensation coefficient corresponding to the third pixel point. The first pixel point is a pixel point located on one side of the midline of the first direction, and the position of the second pixel point in the first direction is symmetrical with the position of the first pixel point in the first direction relative to the midline of the first direction, that is, the position of the second pixel point in the first direction is symmetrical with the position of the first pixel point in the first direction relative to the midline of the first direction. The third pixel point is a pixel point located on one side of the midline of the second direction. The position of the fourth pixel point in the second direction is symmetrical with the position of the third pixel point in the second direction relative to the midline of the second direction.

[0085] For example, Figure 3 and Figure 4 As shown, the first pixel point is any pixel point in the upper half of the screen, that is, above the midline in the X direction, the second pixel point is a pixel point in the lower half of the screen (that is, below the midline in the X direction), and is symmetrical with the position of the first pixel point in the X direction relative to the midline in the X direction, the third pixel point is any pixel point in the left half of the screen (that is, to the left of the midline in the Y direction), and the fourth pixel point is a pixel point in the right half of the screen (that is, to the right of the midline in the Y direction), and is symmetrical with the position of the third pixel point in the Y direction relative to the midline in the Y direction. For example, the first pixel point is a pixel point with a position of X_2 in the X direction, and the second pixel point is a pixel point with a position of X_21 in the X direction. For example, the third pixel point is a pixel point with a position of Y_3 in the Y direction, and the fourth pixel point is a pixel point with a position of Y_31 in the Y direction.

[0086] In the case of adopting the mirror compensation method, in the process of determining the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to each pixel, only some coefficients in Table 1 are used. Exemplarily, the coefficients used can be GX1, GX2, GX3, ..., GXm, GY1, GY2, GY3, ..., GYn, or GX1, GX2, GX3, ..., GXm, GY11, GY21, GY31, ..., GYn1, or GX11, GX21, GX31, ..., GXm1, GY1, GY2, GY3, ..., GYn, or GX11, GX21, GX31, ..., GXm1, GY11, GY21, GY31, ..., GYn1.

[0087] When the mirror compensation method is adopted, it is only necessary to determine the voltage compensation coefficients of some pixels according to the coefficient table, which can reduce the processing amount of the mobile terminal, that is, the calculation amount, thereby reducing the processing power consumption of the mobile terminal, that is, the calculation power consumption.

[0088] The following describes how to determine the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to a pixel point according to the coefficient table.

[0089] In some embodiments, when the position in the first direction in the coefficient table includes the position of the fifth pixel in the first direction, the mobile terminal can determine the coefficient corresponding to the first position in the coefficient table as the first voltage compensation coefficient corresponding to the fifth pixel, and when the position in the second direction in the coefficient table includes the position of the fifth pixel in the second direction, the coefficient corresponding to the second position in the coefficient table can be determined as the second voltage compensation coefficient corresponding to the fifth pixel. The fifth pixel is a pixel in the display screen. The first position is the position of the fifth pixel in the first direction. The second position is the position of the fifth pixel in the second direction.

[0090] In some embodiments, when the position in the first direction in the coefficient table does not include the position of the fifth pixel in the first direction, determine the two positions in the first direction included in the coefficient table that are shortest in distance to the first position to obtain the third position and the fourth position, and determine the first voltage compensation coefficient corresponding to the fifth pixel based on the third position, the coefficient corresponding to the third position, and the fourth position and the coefficient corresponding to the fourth position. When the position in the second direction in the coefficient table does not include the position of the fifth pixel in the second direction, determine the two positions in the second direction included in the coefficient table that are shortest in distance to the second position to obtain the fifth position and the sixth position, and determine the second voltage compensation coefficient corresponding to the fifth pixel based on the fifth position, the coefficient corresponding to the fifth position, and the sixth position and the coefficient corresponding to the sixth position.

[0091] The mobile terminal may first determine the position of the fifth pixel in the first direction and the second direction, and may determine whether the position in the first direction in the coefficient table includes the first position. When it is determined that the position in the first direction in the coefficient table includes the first position, the coefficient corresponding to the first position in the coefficient table may be determined as the first voltage compensation coefficient corresponding to the fifth pixel. When it is determined that the position in the first direction in the coefficient table does not include the first position, the mobile terminal may determine the two positions with the shortest distance from the first position among the positions in the first direction included in the coefficient table, and obtain the third position and the fourth position. Then, the first voltage compensation coefficient corresponding to the fifth pixel may be determined using the interpolation method according to the third position, the coefficient corresponding to the third position in the coefficient table, the fourth position, and the coefficient corresponding to the fourth position in the coefficient table.

[0092] Similarly, the mobile terminal can determine whether the position in the second direction in the coefficient table includes the second position. In the case where it is determined that the position in the second direction in the coefficient table includes the second position, the coefficient corresponding to the second position in the coefficient table can be determined as the second voltage compensation coefficient corresponding to the fifth pixel. In the case where it is determined that the position in the second direction in the coefficient table does not include the second position, the mobile terminal can determine the two positions with the shortest distance from the second position among the positions in the second direction included in the coefficient table to obtain the fifth position and the sixth position, and then the second voltage compensation coefficient corresponding to the fifth pixel can be determined using the interpolation method based on the fifth position, the coefficient corresponding to the fifth position in the coefficient table, the sixth position, and the coefficient corresponding to the sixth position in the coefficient table.

[0093] The interpolation method may be a linear interpolation method, a Lagrange interpolation method, a Newton interpolation method, a gamma interpolation method, etc. The linear interpolation method is taken as an example for description.

[0094] For example, Figure 3 and Figure 4 As shown, assuming that the first direction is the X direction, the second direction is the Y direction, the position of the pixel 1 in the X direction is X_2, and the position in the Y direction is Y_2, since the position of the coefficient table in the X direction, that is, the position of the segmentation point in the X direction, includes X_2, the mobile terminal can determine the coefficient GX2 corresponding to X_2 as the first voltage compensation coefficient corresponding to the pixel 1, and since the position of the coefficient table in the Y direction, that is, the position of the segmentation point in the Y direction, includes Y_2, the mobile terminal can determine the coefficient GY2 corresponding to Y_2 as the second voltage compensation coefficient corresponding to the pixel 1.

[0095] For example, Figure 3 and Figure 4As shown, assuming that the first direction is the X direction, the second direction is the Y direction, the position of the pixel 2 in the X direction is X_k, the position in the Y direction is Y_k, and X_k is a value between X_2 and X_3. Since the position in the X direction in the coefficient table does not include X_k, the two positions with the shortest distance from X_k in the X direction included in the coefficient table can be determined, namely X_2 and X_3. Then, according to X_2, GX2, X_3 and GX3, the first voltage compensation coefficient corresponding to the pixel 2 can be determined by linear interpolation. In the case where X_2 is less than X_3, the first voltage compensation coefficient GXk corresponding to the pixel 2 can be expressed as follows:

[0096] GXk=(X_k-X_2)*(GX3-GX2) / (X_3-X_2)+GX2

[0097] Y_k is a value between Y_1 and X_2. Since the Y-direction position in the coefficient table does not include Y_k, the two positions in the Y-direction position included in the coefficient table, namely Y_1 and Y_2, which are the shortest distances from Y_k, can be determined. Then, the second voltage compensation coefficient corresponding to pixel point 2 can be determined using linear interpolation based on Y_1, GY1, Y_2, and GY2. When Y_1 is less than Y_2, the second voltage compensation coefficient GYk corresponding to pixel point 2 can be expressed as follows:

[0098] GYk=(Y_k-Y_1)*(GY2-GY1) / (Y_2-Y_1)+GY1

[0099] It should be understood that the above is an exemplary description of determining the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to the pixel point according to the coefficient table, and is not limited thereto. For example, other interpolation methods can be used to determine the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to the pixel point.

[0100] 204. Determine a target voltage corresponding to each pixel point according to a voltage compensation coefficient and a source voltage corresponding to each pixel point.

[0101] The mobile terminal can determine the target voltage corresponding to each pixel point according to the voltage compensation coefficient corresponding to each pixel point and the source voltage, that is, according to the voltage compensation coefficient corresponding to each pixel point, the voltage corresponding to each pixel point can be adjusted from the source voltage to the target voltage. The target voltage corresponding to each pixel point is greater than or equal to the corresponding source voltage, that is, the voltage corresponding to each pixel point is adjusted, that is, the voltage corresponding to the pixel point is increased, or the voltage corresponding to the pixel point is kept unchanged.

[0102] When the voltage compensation coefficient corresponding to the pixel point includes the first voltage compensation coefficient and the second voltage compensation coefficient, the mobile terminal can determine the target voltage corresponding to each pixel point based on the first voltage compensation coefficient, the second voltage compensation coefficient and the source voltage corresponding to each pixel point.

[0103] The first voltage compensation coefficient corresponding to the pixel point may be greater than 1, may be equal to 1, or may be less than 1. Similarly, the second voltage compensation coefficient corresponding to the pixel point may be greater than 1, may be equal to 1, or may be less than 1.

[0104] In some embodiments, the mobile terminal can determine the first voltage corresponding to each pixel point based on the first voltage compensation coefficient and the source voltage corresponding to each pixel point, and can determine the second voltage corresponding to each pixel point based on the second voltage compensation coefficient and the source voltage corresponding to each pixel point, and then can determine the target voltage corresponding to each pixel point based on the first voltage and the second voltage corresponding to each pixel point.

[0105] When the first voltage compensation coefficient corresponding to each pixel is greater than or equal to 1, the first voltage corresponding to the pixel is positively correlated with the first voltage compensation coefficient. When the second voltage compensation coefficient corresponding to each pixel is greater than or equal to 1, the second voltage corresponding to the pixel is positively correlated with the second voltage compensation coefficient. The positive correlation may be a linear positive correlation or a nonlinear positive correlation.

[0106] When the first voltage compensation coefficient corresponding to each pixel is less than or equal to 1, the first voltage corresponding to the pixel is anti-correlated with the first voltage compensation coefficient. When the second voltage compensation coefficient corresponding to each pixel is less than or equal to 1, the second voltage corresponding to the pixel is anti-correlated with the second voltage compensation coefficient. The anti-correlation may be linear anti-correlation or nonlinear anti-correlation.

[0107] When the positive correlation is a linear positive correlation, the mobile terminal can determine the first voltage corresponding to each pixel point by multiplying the first voltage compensation coefficient corresponding to each pixel point and the source voltage, and can determine the second voltage corresponding to each pixel point by multiplying the second voltage compensation coefficient corresponding to each pixel point and the source voltage.

[0108] Exemplarily, assuming that the coefficients corresponding to pixel point 1 are GX2 and GY2, the first voltage and the second voltage corresponding to pixel point 1 can be expressed as follows:

[0109] V1=GX2*Vs

[0110] V2=GY2*Vs

[0111] Among them, V1 represents the first voltage corresponding to pixel point 1, V2 represents the second voltage corresponding to pixel point 1, and Vs represents the source voltage corresponding to pixel point 1.

[0112] It should be understood that the above is an exemplary description of determining the first voltage and the second voltage corresponding to the pixel point, and does not limit it.

[0113] The mobile terminal can determine the larger value of the first voltage and the second voltage corresponding to each pixel as the target voltage corresponding to each pixel. Since the display power consumption of the display screen is inversely correlated with the voltage corresponding to the pixel, the display power consumption of the display screen can be reduced.

[0114] The mobile terminal can also determine the average value or weighted average value of the first voltage and the second voltage corresponding to each pixel as the target voltage corresponding to each pixel, which can be compatible with voltage compensation in two directions, avoid voltage mutations, and ensure the smoothness of the picture, thereby improving the display effect while reducing display power consumption.

[0115] In some embodiments, the mobile terminal can first determine the target voltage compensation coefficient corresponding to each pixel point based on the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to each pixel point, and then determine the target voltage corresponding to each pixel point based on the target voltage compensation coefficient and the source voltage corresponding to each pixel point.

[0116] When the target voltage compensation coefficient corresponding to each pixel is greater than or equal to 1, the target voltage corresponding to each pixel is positively correlated with the target voltage compensation coefficient. The positive correlation may be a linear positive correlation or a nonlinear positive correlation.

[0117] The mobile terminal can determine the larger value of the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to each pixel as the target voltage compensation coefficient corresponding to each pixel. Since the display power consumption of the display screen is inversely correlated with the voltage corresponding to the pixel, the display power consumption of the display screen can be reduced.

[0118] When the target voltage compensation coefficient corresponding to each pixel is less than or equal to 1, the target voltage corresponding to each pixel is anti-correlated with the target voltage compensation coefficient. The anti-correlation may be linear anti-correlation or nonlinear anti-correlation.

[0119] The mobile terminal can determine the smaller value of the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to each pixel as the target voltage compensation coefficient corresponding to each pixel. Since the display power consumption of the display screen is inversely correlated with the voltage corresponding to the pixel, the display power consumption of the display screen can be reduced.

[0120] The mobile terminal may also determine the average value of the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to each pixel as the target voltage compensation coefficient corresponding to each pixel, and may also determine the weighted average value of the first voltage compensation coefficient and the second voltage compensation coefficient corresponding to each pixel as the target voltage compensation coefficient corresponding to each pixel. Since the voltage compensation in two directions is compatible, the voltage mutation can be avoided, the smoothness of the picture can be guaranteed, and the display effect can be improved while reducing the display power consumption.

[0121] 205. Drive the corresponding pixel point according to the target voltage corresponding to each pixel point, so that the display screen displays the data to be displayed.

[0122] The detailed description of step 205 may refer to the description of step 104 .

[0123] exist Figure 2 In the data display method shown, the voltage corresponding to each pixel is inversely correlated with the current of the organic light emitting diode corresponding to each pixel, that is, the larger the voltage corresponding to each pixel, the smaller the current of the organic light emitting diode corresponding to each pixel. Since the voltage corresponding to some or all pixels is increased by coefficient compensation, the current of the organic light emitting diode corresponding to some or all pixels can be reduced. Since the display power consumption of the display screen is positively correlated with the current of the organic light emitting diode, the display power consumption of the display screen can be reduced. In addition, since the voltage corresponding to the pixel is adjusted, the smoothness of the picture can be guaranteed, and the display effect can be guaranteed while reducing the display power consumption.
