[0030] It should be noted that the implementation methods provided in the embodiments of the present invention can be combined with each other if there is no contradiction.

[0031] Figure 1 is a schematic diagram of the structure of a display panel provided by an embodiment of the present invention, such as Figure 1 As shown, the display panel 100 includes a plurality of pixels 10 arranged in an array. By providing a data signal to each pixel 10 one by one, each pixel 10 can be made to display and emit light according to the data signal, so that the display panel 100 presents a corresponding picture.

[0032] It is understandable that the display panel 100 may be a self-luminous display panel or a non-self-luminous display panel, and the embodiment of the present invention does not specifically limit this. Among them, when the display panel 100 is a self-luminous display panel, the pixel 10 of the display panel 100 may include a pixel circuit and a light-emitting element, and the pixel circuit can control the light-emitting brightness of the light-emitting element according to the data signal received by it, so that the display panel 100 can present a corresponding display picture; when the display panel 100 is a non-self-luminous display panel, the pixel 10 in the display panel 100 can realize display light by reflecting or transmitting an external light source. For example, when the display panel 100 is a liquid crystal display panel, the pixel 10 of the display panel 100 may include a pixel electrode, a common electrode and a liquid crystal layer. The pixel electrode and the common electrode can generate a corresponding electric field according to the received data signal and the common voltage signal, and the electric field can control the twisting of the liquid crystal molecules in the liquid crystal layer to control the transmittance of the light provided by the backlight module, so that the pixel 10 displays light, and the display panel 100 presents a corresponding display picture. For the convenience of description, without any special limitation, the embodiments of the present invention all take the display panel being a self-luminous display panel as an example to exemplarily illustrate the technical solutions of the embodiments of the present invention.

[0033] Continue to refer Figure 1 The display panel 100 further includes a plurality of data lines D and a plurality of gate lines G. The plurality of data lines D extend in the column direction, and the plurality of gate lines G extend in the row direction. The data lines D and the gate lines G are staggered to define pixels 10. At least some of the pixels 10 in the same column can be connected to the same data line D, and at least some of the pixels 10 in the same row can be connected to the same gate line G. The gate driving signal transmitted through the gate line G can scan the pixels 10 in each row row by row, so that the data lines D can write data signals to the pixels 10 in each row in a time-sharing manner.

[0034] In addition, the display panel 100 further includes a display area AA and a non-display area BB, and the non-display area BB at least partially surrounds the display area AA. A driver chip 30 may be provided in the non-display area BB, and the driver chip 30 may include a data driver circuit 320 and a thrust adjustment circuit 310. The thrust adjustment circuit 310 is electrically connected to the data driver circuit 320, and the data driver circuit 320 may be electrically connected to each data line D respectively, and the data driver circuit 320 may provide a data signal to each data line D respectively, and the thrust adjustment circuit 310 may adjust the thrust of the data signal provided by the data driver circuit 320 to each data line D. The thrust of the data signal provided by the data driving circuit 320 can be understood as the output power when the data driving circuit 320 outputs the data signal. The greater the thrust of the data driving circuit 320 providing the data signal, the greater the output power of the data driving circuit 320, the stronger the charging ability of the data driving circuit 320 to charge the data line D, and the faster the data signal on the data line D can be written into the pixel 10. However, since the greater the power, the higher the power consumption, the greater the output power of the data driving circuit 320, the greater the power consumption of the data driving circuit 320 and the display panel 100. Conversely, the smaller the thrust of the data signal provided by the data driving circuit 320, the smaller the output power of the data driving circuit 320, and the smaller the power consumption of the display panel 100.

[0035] In addition, when the display panel 100 displays a picture, the interval time of writing a data signal to the pixel 10 is controlled according to the display requirements, and the number of times the data signal is written to the pixel 10 per unit time is the refresh frequency of the pixel 10. The driving mode of the display panel 100 may include a single-frequency driving mode and a multi-frequency driving mode. In the single-frequency driving mode, the refresh frequency of each pixel 10 in the display area AA of the display panel 100 is the same. In the multi-frequency driving mode, the display area AA of the display panel may include multiple display areas, and the pixels 10 in different display areas may have different refresh frequencies.

[0036] In the prior art, when the current driving mode of the display panel 100 is a multi-frequency driving mode, a data driving circuit 320 is used to provide data signals of each row of pixels 10 in a time-sharing manner, and by controlling the gate driving signal provided to the gate line G connected to the pixels 10 in each display area, when the pixel 10 receives the effective level of the gate driving signal, the data signal output by the data driving circuit 320 can be written into the pixel 10, and when the pixel 10 receives the invalid level of the gate driving signal, the data signal output by the data driving circuit 320 cannot be written into the pixel 10. In this way, by controlling the effective level interval time of the gate driving signal provided to each pixel 10 in each display area, the refresh frequency of each pixel 10 in each display area can be controlled, so that the display panel 100 can include a display area with a high refresh frequency and a display area with a low refresh frequency.

[0037] However, in the prior art, the refresh frequency of the pixels 10 in each display area is controlled by controlling the effective level interval time of the gate driving signal provided to each pixel, and the thrust adjustment circuit 310 controls the data driving circuit 320 to provide the data signal to each data line D so that the thrust size remains unchanged, that is, the data driving circuit 320 provides data signals with the same thrust to display areas with different refresh frequencies. In this way, the requirements of display areas with different refresh frequencies for different thrust sizes cannot be met. If the data driving circuit 320 provides the data signals with a small thrust to the multiple data lines D, the pixels 10 in the display area with a higher refresh frequency cannot be quickly charged, resulting in a poor display effect of the display panel 10. If the data driving circuit 320 provides the data signals with a large thrust to the multiple data lines D, the thrust will be wasted in the time period when the data signal does not need to be provided to the display area with a lower refresh frequency, which is not conducive to the low power consumption of the driver chip 30 and the display panel 100.

[0038] In order to solve the above technical problems, an embodiment of the present invention provides a method for driving a display panel, which can save the power consumption of the display panel and improve the display quality of the display panel. The method for driving a display panel of the embodiment of the present invention can control the display panel provided by the embodiment of the present invention to display a picture, and can be executed by using a driving device for the display panel provided by the embodiment of the present invention. The driving device for the display panel can be implemented by software and / or hardware, and the driving device for the display panel can be integrated in a driving chip for driving the display panel. Figure 2 is a flow chart of a method for driving a display panel provided by an embodiment of the present invention, such as Figure 1 and Figure 2 As shown,

[0039] S10. When the current driving mode of the display panel is the multi-frequency driving mode, determine the refresh frequency of each pixel in the display panel under the current driving mode.

[0040] It is understandable that the driving mode of the display panel 100 may include a single-frequency driving mode and a multi-frequency driving mode. When different pixels 10 in the display panel 100 have different refresh frequencies, it can be determined that the current driving mode of the display panel 100 is a multi-frequency driving mode. In the multi-frequency driving mode, the display panel 100 may include a plurality of display areas with different refresh frequencies. For example, when the current display screen of the display panel 100 includes a static image and a dynamic image, the current driving mode of the display panel 100 may be set to a multi-frequency driving mode. At this time, the dynamic image can be displayed by the display area with a higher refresh frequency, and the static image can be displayed by the display area with a lower refresh frequency, so that the display effect of the dynamic image can be guaranteed while reducing the number of times that the data signal is provided to each pixel in the display area of ​​the static image per unit time, which is beneficial to the low power consumption of the display panel.

[0041] It can also be understood that the driving cycle of the pixel 10 with a higher refresh frequency includes at least a data writing frame, and the driving cycle of the pixel 10 with a lower refresh frequency includes at least a data writing frame and at least one holding frame. When the time period for providing a data signal to the pixel 10 is the data writing phase of the pixel 10, the data writing frame may include the data writing phase, while the holding frame does not include the data writing phase, so that the data signal in the pixel 10 remains unchanged in the holding frame, thereby saving power consumption waste caused by writing the data signal.

[0042] When each display area of ​​the display panel 100 displays images at the maximum refresh rate f0, the driving cycle of each pixel 10 in the display panel 100 may only include a data writing frame, that is, the duration of the data writing frame may be equal to 1 / f0. 00 The screen is displayed, and f 00 When f0 is less than or equal to f0, the driving period of each pixel 10 of the display panel 100 may include a data writing frame and at least one holding frame, and the duration of the data writing frame and the holding frame may both be equal to 1 / f0.

[0043] Specifically, since the number of times that data signals are provided to the display area with a higher refresh frequency per unit time is greater than the number of times that data signals are provided to the display area with a lower refresh frequency, the pixels 10 in the display area with a lower refresh frequency are in a holding frame during the time period when part of the data of the pixels 10 in the display area with a higher refresh frequency is written into the frame. When it is determined that the current driving mode of the display panel 100 is the multi-frequency driving mode, the refresh frequency of each pixel 10 in the display panel 100 in the current driving mode is determined, and the display areas with different refresh frequencies are divided according to the refresh frequency of each pixel 10 in the current driving mode, for example, the area where the pixels 10 with a higher refresh frequency in the display panel 100 are located is divided into the first display area AA1, and the area where the pixels 10 with a lower refresh frequency in the display panel 100 are located is divided into the second display area AA2. In this way, an image with a higher refresh frequency requirement is displayed through the first display area AA1, and an image without a higher refresh frequency requirement is displayed through the second display area AA2, thereby reducing the display power consumption of the display panel while improving the display effect of the display panel.

[0044] It should be noted that the above embodiment is illustratively described by taking the refresh frequency of the pixels 10 in the first display area AA1 as greater than the refresh frequency of the pixels 10 in the second display area AA2, but is not limited to this. In other embodiments, the refresh frequency of the pixels 10 in the first display area AA1 may also be less than the refresh frequency of the pixels 10 in the second display area AA2, and those skilled in the art may set it as needed.

[0045] It should also be noted that the above embodiment is exemplified by taking the case where the pixels 10 in the display panel 100 have two different refresh frequencies as an example, but this is not a limitation. When the pixels 10 in the display panel 100 have more than two different refresh frequencies, for any two display areas in the display panel 100, the first display area AA1 can refer to a display area with a relatively high refresh frequency, and the second display area can refer to an AA2 display area with a relatively low refresh frequency. At the same time, the embodiment of the present invention divides the display area by different refresh frequencies without limiting the number and position of different display areas. In one embodiment, if Figure 1 As shown, the display panel 100 includes a first display area AA1 and two second display areas AA2, and along the column direction of the pixels 10, the first display area AA1 is located between the two second display areas AA2. Figure 3 As shown, the display panel 100 includes a first display area AA1 and a second display area AA2 arranged along the column direction of the pixels 10. In other embodiments, as Figure 4As shown, the display panel 100 may include three display areas A01, A02 and A03 with different refresh frequencies. When the refresh frequency of the pixels 10 in the display area A01 is greater than the refresh frequency of the pixels 10 in the display area A02, the display area A01 may be the first display area and the display area A02 may be the second display area in the two display areas; when the refresh frequency of the pixels 10 in the display area A02 is greater than the refresh frequency of the pixels 10 in the display area A03, the display area A02 may be the first display area and the display area A01 may be the second display area in the two display areas; similarly, when the refresh frequency of the pixels 10 in the display area A01 is greater than the refresh frequency of the pixels 10 in the display area A03, the display area A01 may be the first display area and the display area A02 may be the second display area in the two display areas. In the embodiment of the present invention, the distribution position and number of the first display area and the second display area can be set by those skilled in the art as needed.

[0046] In addition, in the embodiment of the present invention, display areas with different refresh frequencies can be arranged in the direction of rows and / or columns of each pixel 10, and can be specifically designed according to actual needs. The embodiment of the present invention does not make specific limitations on this. For the convenience of description, the embodiment of the present invention takes the display areas with different refresh frequencies arranged in the column direction of each pixel 10, and the display panel 100 includes two display areas with different refresh frequencies as an example, and exemplarily illustrates the technical solution of the embodiment of the present invention.

[0047] S20. During at least a portion of the display time in the current driving mode, control the data driving circuit to provide data signals with different thrusts to the pixels in the first display area and the pixels in the second display area, respectively.

[0048] Among them, Figure 3 As shown, at least part of the display time in the current driving mode can be a time period when the pixels 10 of the first display area AA1 and the pixels 10 of the second display area AA2 are both in the data writing frame, or, it can also be a time period when the pixels 10 in the display area with a higher refresh rate in the first display area AA1 and the second display area AA2 are in the data writing frame, and the pixels 10 in the display area with a lower refresh rate are in the holding frame.

[0049] It is understandable that the driver chip 30 periodically obtains grayscale data from the system motherboard, and the grayscale data obtained by the driver chip 30 is parsed into the data signal of each pixel 10, so that in the data writing stage of each pixel 10, the data driving circuit 320 can output the data signal of each pixel 10 correspondingly, and write it into each pixel 10 one by one. The number of times the driver chip 30 obtains grayscale data from the system motherboard per unit time can be the same as the basic refresh frequency of the display panel 100, that is, it can be the same as the minimum value of the refresh frequency of each display area in the display panel 100, and the basic refresh frequency can be less than or equal to the maximum refresh frequency of the display panel 100 for displaying the picture. In this way, when each pixel 10 in the display panel 100 is in the data writing frame, the driver chip 30 will obtain grayscale data from the system motherboard, and the grayscale data after parsing includes data signals corresponding to each pixel 10 in the display panel 100 one by one. The driver chip 30 obtains the grayscale data signal and can control whether to write the data signal to each pixel 10 according to actual needs. Regardless of whether the data signal needs to be written to each pixel 10, the data driver circuit 320 will output the data signal of each row of pixels 10 in sequence.

[0050] In addition, the driver chip 30 may be provided with a data register 330, which may store the data signals of each row of pixels 10 in the data register 330 in sequence, and when the data driving circuit 320 needs to output the data signals corresponding to the nth row of pixels 10, the data register 330 may provide the data signals of the nth row of pixels 10 stored therein to the data driving circuit 320, and at the same time, the data signals of the n+1th row of pixels may continue to be stored in the data register 330, that is, after the data signals of the previous row of pixels 10 are provided to the data driving circuit 320, the data register 330 may store the data signals of the next row of pixels 10. In this way, the thrust adjustment circuit 310 may adjust the thrust of the data signals provided by the data driving circuit 320 to each row of pixels 10 according to the control requirements of each row of pixels 10. Wherein, n is a positive integer.

[0051] Exemplarily, when the pixels 10 in the i-th row are located in a display area with a higher refresh rate, and the pixels 10 in the j-th row are located in a display area with a lower refresh rate, and the current time period is a data writing frame for the pixels 10 in the i-th row and a holding frame for the pixels 10 in the j-th row, in the data writing frame for the pixels 10 in the i-th row, it is necessary to use a faster charging speed to provide data signals to the pixels 10 in the i-th row, so that sufficient data signals can be written to the pixels 10 in the i-th row during the data signal writing phase for the pixels 10 in the i-th row, so as to ensure the display luminescence accuracy of the pixels 10 in the i-th row. At this time, the thrust adjustment circuit 310 can control the data driving circuit 320 to output The data signal of the i-th row pixel 10 has a larger thrust, thereby ensuring that the i-th row pixel 10 can complete charging quickly, thereby ensuring the display effect of the display area with a higher refresh frequency; in the holding frame of the j-th row pixel 10, there is no need to write the data signal to the j-th row pixel, so there is no need to write the data signal faster. At this time, the thrust adjustment circuit 310 can control the data driving circuit 320 to provide the j-th row pixel 10 with a data signal with a smaller thrust, thereby reducing the power of the data driving circuit 320 in this time period, and reducing the power consumption of the pixels 10 in the display area with a lower refresh frequency in the display panel 100.

[0052] It is understandable that the above-mentioned embodiment is illustratively described by taking the display area with low refresh frequency using a data signal with smaller thrust as an example, but it is not limited to this. In other embodiments, since the display area with low refresh frequency writes data signals at a long interval, there may be leakage and loss of signals during this interval, resulting in a lower potential in the pixel 10. In order to quickly write data signals in the data writing frame of the pixel 10 in the display area with low refresh frequency, at this time, the thrust adjustment circuit 310 can also be used to control the data driving circuit 320 to provide the pixel 10 in the display area with low refresh frequency with a data signal with a larger thrust, so that the data signal writing conditions of the display area with higher refresh frequency and the display area with lower refresh frequency can be kept consistent, thereby improving the display uniformity of the display panel.

[0053] In summary, when the current driving mode of the display panel is the multi-frequency driving mode, the refresh frequency of each pixel in the display panel under the current driving mode is determined, so that according to the display requirements of the display panel, the pixels 10 in different display areas can be controlled to write data signals at different refresh frequencies, so as to reduce the power consumption of the display panel 100 while ensuring that the display panel 100 has a high display effect; at the same time, during at least part of the display time in the current driving mode, according to the refresh frequency of the pixels 10 in different display areas, the thrust adjustment circuit 310 is used to adjust the data driving circuit 320 to provide data signals with different thrust sizes to the pixels 10 in the display areas with different refresh frequencies, so that the pixels 10 in the display areas with different refresh frequencies can write data signals through different thrusts, which is beneficial to reduce the power consumption of the display panel and improve the display quality of the display panel.

[0054] In an optional embodiment, continue to refer to Figure 3 , controlling the data driving circuit 320 to provide data signals with different thrusts to the pixels 10 of the first display area AA1 and the pixels 10 of the second display area AA2, respectively, including: providing data signals with a first preset thrust to the pixels 10 of the first display area AA1, and providing data signals with a second preset thrust to the pixels of the second display area AA2, wherein the refresh frequency of the pixels of the first display area AA1 is greater than the refresh frequency of the pixels 10 of the second display area AA2, and the second preset thrust is less than the first preset thrust.

[0055] Specifically, the refresh frequency of the pixels in the first display area AA1 is greater than the refresh frequency of the pixels 10 in the second display area AA2, so that the first display area AA1 can be a display area with a higher refresh frequency, and the second display area AA2 can be a display area with a lower refresh frequency. When the time for providing data signals with different thrusts to the pixels 10 in the first display area AA1 and the pixels 10 in the second display area AA2 is the data writing frame of the pixels 10 in the first display area AA1 and the holding frame of the pixels 10 in the second display area AA2, in the data writing frame of the pixels 10 in the second display area AA2, it is necessary to use a faster charging speed to provide data signals to the pixels 10 in the second display area AA2, and then the thrust adjustment circuit 310 adjusts the thrust of the data signal provided by the data driving circuit 320 according to the refresh frequency of the pixels 10 in the first display area AA1, so that the data driving circuit 320 provides the data signals with a larger thrust, that is, the data signals with the first preset thrust, to each row of pixels 10 in the first display area AA1, thereby ensuring that the pixels 10 in the first display area AA1 can It is enough to quickly write the data signal, thereby ensuring the display effect of the first display area AA1 with a higher refresh frequency; in addition, in the holding frame of the pixels 10 in the second display area AA2, there is no need to write the data signal into the pixels 10 in the second display area AA2, that is, the pixels 10 in the second display area AA2 do not need to quickly write the data signal. At this time, the thrust adjustment circuit 310 can adjust the thrust of the data signal provided by the data driving circuit 320 according to the refresh frequency of the pixels 10 in the second display area AA2, so that the data driving circuit 320 provides each row of pixels 10 in the second display area AA2 with a data signal with a smaller thrust, that is, a data signal with a second preset thrust, so that the data driving circuit 320 has a lower output power, reduces the power consumption of the data driving circuit 320, and reduces the power consumption of the display panel.

[0056] It should be noted that the embodiment of the present invention does not limit the specific values ​​of the first preset thrust and the second preset thrust. It only needs to ensure that the first preset thrust is greater than the second preset thrust. Those skilled in the art can set them as needed.

[0057] In an optional embodiment, the thrust value of the second preset thrust is 0.

[0058] Among them, continue to refer to Figure 3, the thrust adjustment circuit 310 can adjust the thrust of the data signal provided by the data driving circuit 320, and different thrust value ranges can correspond to different thrust gears. The lower the thrust gear, the smaller the thrust value, the lower the output power of the data signal provided by the data driving circuit 320, and the lower the power consumption of the data driving circuit 320. Among them, when the thrust adjustment circuit 310 adjusts the thrust of the data signal provided by the data driving circuit 320 to the thrust of the lowest thrust gear, the thrust value of the data signal provided by the data driving circuit 320 can be 0, and the power consumption of the data driving circuit 320 is the lowest. As the thrust gear increases, the thrust value of the data signal provided by the data driving circuit 320 becomes larger, and the power consumption of the data driving circuit 320 becomes larger.

[0059] Specifically, since the pixels 10 in the first display area AA1 have a higher refresh frequency, and the pixels 10 in the second display area AA2 have a lower refresh frequency, the pixels 10 in the first display area AA1 are in a data writing frame, and the pixels 10 in the second display area AA2 are in a time period of a holding frame, and there is no need to write data signals into the pixels 10 in the second display area AA2, so there is no need for faster writing data signals. At this time, the thrust adjustment circuit 310 adjusts the data driving circuit 320 to provide data signals with a thrust value of 0 for each row of pixels 10 in the second display area AA2, thereby reducing the power consumption of the data driving circuit 320 and the display panel 100 to the greatest extent.

[0060] It is understandable that, since the data signal output by the data driving circuit 320 does not need to be written into the pixel 10 in the holding frame of the pixel 10, when the data driving circuit 320 needs to provide a data signal to the pixel 10 in the holding frame of the pixel 10, the data signal output by the data driving circuit 320 can be a data signal corresponding to the pixel 10 or other data signals; and in the data writing frame of the pixel 10, the data signal output by the data driving circuit 320 needs to be written into the pixel 10, so that in the data writing stage of the data writing frame of the pixel 10, the data driving circuit 320 needs to provide the data signal corresponding to the pixel 10. Under the premise of not affecting the display effect of the display panel, the embodiment of the present invention does not make specific limitations on this.

[0061] In an optional embodiment, continue to refer to Figure 3 The data signal provided to the pixel 10 of the first display area AA1 is a data signal corresponding to the grayscale of the pixel 10 of the first display area AA1 in the current picture display frame; the data signal provided to the pixel 10 of the second display area AA2 is a set data signal.

[0062] Specifically, when the pixels 10 in the first display area AA1 are in the data writing frame and the pixels 10 in the second display area AA2 are in the frame holding period, the driver chip 30 obtains the grayscale data of the current picture in the display panel 100 from the system mainboard, and after parsing the grayscale data, determines the data signals corresponding to each row of pixels 10. Taking the display panel 100 as an example, in which n rows of pixels are included, and the first row of pixels 10 to the i-th row of pixels 10 are located in the first display area AA1, and the i+1-th row of pixels 10 to the n-th row of pixels 10 are located in the second display area AA2, the data driver circuit 320 sequentially obtains the data signals of the first row of pixels 10 to the i-th row of pixels 10 from the data register 330, and outputs the data signals of the rows of pixels 10 at the first preset thrust during the data writing phase of each row of pixels 10 in the first row of pixels 10 to the i-th row of pixels 10, so that each row of pixels 10 in the first row of pixels 10 to the i-th row of pixels 10 can write data signals one by one, thereby ensuring the display luminescence accuracy of each pixel 10 in the first display area AA1. After completing the writing of the data signals of the first row of pixels 10 to the i-th row of pixels 10, that is, after the data writing stage of the i-th row of pixels 10, the data driving circuit 320 can stop obtaining the data signals of the i+1-th row of pixels 10 to the n-th row of pixels 10 from the data register 330, but adjust the data signal at its output end to a set data signal, and output the set data signal with a second preset thrust; until entering the data writing stage of the first row of pixels 10 again, the data driving circuit 320 will obtain the data signals of the first row of pixels 10 from the data register 330 again, and write them into the first row of pixels 10 one by one. In this way, during the time period after the data writing stage of the pixels 10 in the i-th row and before the data writing stage of the pixels 10 in the first row is entered again, the data driving circuit 320 can continuously output the set data signal, so that the data signal outputted from the output end of the data driving circuit 320 remains unchanged, thereby preventing the data driving circuit 320 from generating additional power consumption due to repeated jumps of the signal at the output end of the data driving circuit 320, and preventing the data line D from being repeatedly charged / discharged and generating corresponding power consumption due to repeated jumps of the data signal outputted by the data driving circuit 320, thereby helping to reduce the overall power consumption of the data driving circuit 320 and the display panel 100.

[0063] In an optional embodiment, continue to refer to Figure 3 The set data signal is the data signal corresponding to the gray scale of the pixel 10 which is last provided to the pixel 10 in the display panel 100 before the data signal is provided to the pixel 10 in the second display area AA2.

[0064] Exemplarily, taking the case where the first row of pixels 10 to the i-th row of pixels 10 are located in the first display area AA1, and the i+1-th row of pixels 10 to the n-th row of pixels 10 are located in the second display area AA2, the data driving circuit 320 sequentially outputs the data signals of the first row of pixels 10 to the i-th row of pixels 10, and writes them one by one into each pixel 10 of the first display area AA1; after completing the data writing phase for the i-th row of pixels 10, the data signals output by each output terminal of the data driving circuit 320 can be maintained as data signals corresponding to each pixel 10 in the i-th row until the data writing phase for the first row of pixels 10 is entered again. In this way, the data signals of each output terminal of the data driving circuit 320 remain unchanged during the period after the data writing phase for the i-th row of pixels 10 to before the data writing phase for the first row of pixels 10 is entered again, so that the output terminal of the data driving circuit 320 and the data line D do not need to be repeatedly charged / discharged, thereby facilitating low power consumption of the data driving circuit 320 and the display panel 100.

[0065] In yet another optional embodiment, the voltage of the set data signal is a fixed value.

[0066] For example, continue to refer to Figure 3 , continue to take the case where the first row of pixels 10 to the i-th row of pixels 10 are located in the first display area AA1, the i+1-th row of pixels 10 to the n-th row of pixels 10 are located in the second display area AA2, and the first row of pixels 10 to the n-th row of pixels 10 are arranged in sequence from the side away from the driving chip to the side close to the driving chip. After completing the data writing phase for the i-th row of pixels 10, the voltage of the data signal output by each output terminal of the data driving circuit 320 can be adjusted to a fixed value until the data writing phase for the first row of pixels 10 is entered again. In this way, the voltage of the data signal at each output terminal of the data driving circuit 320 is maintained at a fixed value during the period after the data writing phase for the i-th row of pixels 10 to before the data writing phase for the first row of pixels 10 is entered again, so that there is no need to repeatedly charge / discharge the output terminal of the data driving circuit 320 and the data line D, which is beneficial to low power consumption of the data driving circuit 320 and the display panel 100.

[0067] In addition, when the voltages of the data signals at the output ends of the data driving circuit 320 are all fixed values, if the data writing stage of the first row of pixels 10 is entered again, the output ends of the data driving circuit 320 can output the data signals of the pixels 10 in the first row on the basis of the fixed voltage, so that the data lines D can be charged with the data signals of the pixels 10 in the first row on the basis of the fixed voltage, thereby ensuring the writing accuracy of the pixels 10 in the first row and improving the display quality of the display panel 100.

[0068] It should be noted that the embodiments of the present invention do not limit the voltage of the fixed value, and those skilled in the art can set it as needed. In one embodiment, the fixed value can be the voltage of the data signal corresponding to grayscale 0, and in other embodiments, the fixed value can also be the signal of the maximum voltage that the driver chip can output.

[0069] Optionally, based on the above embodiment, Figure 5 is a structural schematic diagram of another display panel provided by an embodiment of the present invention, Figure 6 is a schematic diagram of a gate drive circuit provided by an embodiment of the present invention, with reference to Figure 5 and Figure 6 The display panel 100 also includes a gate driving circuit 40, which provides a gate driving signal G to each row of pixels 10 respectively; at this time, the driving method of the display panel 100 also includes: within the display time of one frame of the display panel 100, providing a refresh control signal Ctrl to the gate driving circuit 40 to control the gate driving circuit 40 to provide a gate driving signal Gout to each row of pixels 10.

[0070] Among them, the gate driving circuit 40 can be located in the non-display area BB of the display panel 100, or, in other feasible embodiments, the gate driving circuit 40 can also be located in the display area of ​​the display panel 100, so as to help reduce the border size of the display panel 100, so as to achieve a narrow border or even a borderless display panel 100.

[0071] Specifically, the gate drive circuit 40 may include a multi-stage shift register unit 41 cascaded with each other, and each stage of the shift register unit 41 is electrically connected to each gate line G, so that each stage of the shift register unit 41 can provide a gate drive signal Gout to each gate line G under the control of the refresh control signal Ctrl. In the time period when each pixel 10 in the display panel 100 needs to write a data signal, the refresh control signal Ctrl can control the effective level time of the gate drive signal Gout provided by each stage of the shift register unit 41 to shift in sequence, so as to ensure that the data signal of each row of pixels 10 provided by the data drive circuit 320 in time division can be written into each pixel 10 one by one; in the time period when each pixel 10 in the display panel 100 does not need to write a data signal, that is, each pixel 10 in the display panel 100 is in the time period of maintaining the frame, the refresh control signal Ctrl can control the invalid level of the gate drive signal Gout provided by the shift register unit 41 at each stage, so that the data signal provided by the data drive circuit 320 cannot be written into the pixel 10; when When the display panel 100 includes a first display area AA1 and a second display area AA2, the pixels 10 in the first display area AA1 need to be written with data signals, and the pixels 10 in the second display area AA2 are in a time period in which data signals do not need to be written. The refresh control signal Ctrl can control the gate drive signal Gout output by the shift register unit 41 electrically connected to the pixels 10 in the first display area AA1 to shift in sequence, and control the gate drive signal Gout output by the shift register unit 41 electrically connected to the pixels 10 in the second display area AA2 to remain at an invalid level, so that the data signal provided by the data drive circuit 320 can be written into each pixel 10 of the first display area AA1 one by one, but cannot be written into each pixel 10 of the second display area AA2. In this way, by using the refresh control signal Ctrl to control the gate drive signal output by each level of the shift register unit 41 in the gate drive circuit 40, the pixel 10 that does not need to write the data signal can receive the invalid level of the gate drive signal Gout, thereby reducing the power consumption caused by the charging / discharging of the gate line G due to the jump of the gate drive signal Gout, which is beneficial to further reduce the power consumption of the display panel 100.

[0072] It should be noted that Figure 5 The gate driving circuit 40 is only exemplarily shown to be located in the non-display area BB located on one side of the display area AA. In other embodiments of the present invention, for example Figure 7As shown, when the gate driving circuit 40 is located in the non-display area BB of the display panel 100, the gate driving circuit 40 of the display panel 100 may include a first gate driving circuit 401 and a second gate driving circuit 402 respectively located on opposite sides of the display area AA, the first gate driving circuit 401 may provide a gate driving signal Gout to the pixels 10 located in odd rows, and the second gate driving circuit 402 may provide a gate driving signal Gout to the pixels 10 located in even rows; or Figure 8 As shown, when the gate driving circuit 40 of the display panel 100 includes a first gate driving circuit 401 and a second gate driving circuit 402 respectively located on opposite sides of the display area AA, for the same gate line G, the first gate driving circuit 401 can provide a gate driving signal Gout to the gate line G from the left side of the display area, and the second gate driving circuit 402 can provide a gate driving signal Gout to the gate line G from the right side of the display area. Under the premise that the gate driving signal Gout provided by the gate driving circuit 40 to each row of pixels 10 can be controlled by the refresh control signal Ctrl, the embodiment of the present invention does not specifically limit the setting method of the gate driving circuit in the display panel 100. For the convenience of description, under the premise that there is no special limitation, the embodiments of the present invention take the gate driving circuit being set in the non-display area on one side of the display area as an example to exemplarily illustrate the technical solution of the embodiments of the present invention.

[0073] In an optional embodiment, Fig. 9 is another driving timing diagram of a display panel provided by an embodiment of the present invention, referring to Figure 5 , Figure 6 and Fig. 9 , within the one-frame picture display time of the display panel 100, a refresh control signal Ctrl is provided to the gate driving circuit 40 to control the gate driving circuit 40 to provide the gate driving signal Gout to each row of pixels 10, including: when providing data signals to each pixel 10 in the first display area AA1, the effective level of the refresh control signal Ctrl is provided to the gate driving circuit 40 to control the gate driving circuit 40 to sequentially provide the effective level of the gate driving signal Gout to each row of pixels 10 located in the first display area AA1; when providing data signals to each pixel 10 in the second display area AA2, the invalid level of the refresh control signal Ctrl is provided to the gate driving circuit 40 to control the gate driving circuit 40 to provide the invalid level of the gate driving signal Gout to each row of pixels 10 located in the second display area AA2.

[0074] Among them, the display time of one frame of the display panel 100 can be a driving cycle of the display panel 100, and the driving cycle can be the least common multiple of the data signal refresh cycles of the pixels 10 in each display area AA; or, the display time of one frame of the display panel 100 can also be equal to the data signal refresh cycle of the pixels 10 in the display area AA with the maximum refresh frequency. The specific design can be made according to actual needs, and the embodiment of the present invention does not make specific limitations on this. For the convenience of description, without special limitations, the embodiments of the present invention take the case where the display time of one frame of the display panel 100 is equal to the data signal refresh cycle of the pixels 10 in the display area AA with the maximum refresh frequency as an example to exemplarily illustrate the technical solutions of the embodiments of the present invention.

[0075] Specifically, when the display panel 100 includes a display area AA with different refresh frequencies, in the display time of some frames of the display panel 100, some pixels 10 are in the data writing frame and some pixels 10 are in the holding frame. In the time period when the data driving circuit 320 provides data signals to the pixels 10 in the data writing frame, it is necessary to control the gate driving circuit 40 to provide the gate driving signal Gout including the effective level to the part of the pixels 10. At this time, the driving chip 30 can provide the effective level of the refresh control signal Ctrl to the gate driving circuit 40, so that within the time when the gate driving circuit 40 receives the effective level of the refresh control signal Ctrl, the gate driving circuit 40 can sequentially provide the effective level of the gate driving signal Gout to the corresponding gate lines G, so that the data signals provided by the data driving circuit 320 can be written one by one into the pixels 10 electrically connected to the part of the gate G; and in the data driving circuit 320 During the time period of providing data signals to the pixels 10 in the holding frame, it is necessary to control the gate driving circuit 40 to provide the invalid level of the gate driving signal Gout to the pixels 10. At this time, the driving chip 30 can provide the gate driving circuit 40 with the invalid level of the refresh control signal Ctrl, so that during the time when the gate driving circuit 40 receives the invalid level of the refresh control signal Ctrl, the gate driving signal Gout output by the gate driving circuit 40 is maintained at an invalid level, so that the data signal provided by the data driving circuit 320 cannot be written into the pixel 10; in this way, by controlling the effective level and the invalid level time of the refresh control signal Ctrl provided to the gate driving circuit 40, it is possible to control the gate driving signal Gout output by the gate driving circuit 40, thereby reducing the overall power consumption of the display panel 100 while meeting the data signal refresh requirements of the pixels 10 in the display area AA with a high refresh frequency.

[0076] Exemplarily, taking the case where the first row of pixels 10 to the i-th row of pixels 10 are located in the first display area AA1, and the i+1-th row of pixels 10 to the n-th row of pixels are located in the second display area AA2, when the pixels 10 in the first display area AA1 have a higher refresh rate and the pixels 10 in the second display area AA2 have a lower refresh rate, within the display time of a portion of the frame image, the driving cycle of the pixels 10 in the first display area AA1 includes a data writing frame, and the driving cycle of the pixels 10 in the second display area AA2 includes a holding frame, so that within the display time of the frame image, the refresh control signal Ctrl may include an effective level and an invalid level, and when the data driving circuit 320 provides the data signals of the pixels 10 in each row of the first display area AA1, the driving chip 30 sends a signal to the gate driving circuit 40. An effective level of the refresh control signal Ctrl is provided to control the gate driving circuit 40 to sequentially provide the effective level of the gate driving signal Gout (Gout1, Gout2, ..., Gouti) to the first row of pixels 10 to the i-th row of pixels 10 located in the first display area AA1. At this time, the data signal provided by the data driving circuit 320 can be written one by one into each pixel 10 in the first row to the i-th row; and when the data driving circuit 320 provides data signals to each row of pixels 10 in the second display area AA2, the driving chip 30 provides an invalid level of the refresh control signal Ctrl to the gate driving circuit 40 to control the gate driving circuit 40 to provide an invalid level of the gate driving signal Gout (Gouti+1, Gout i+2, ..., Goutn) to the pixels 10 in the i+1-th row to the n-th row. At this time, the data signal provided by the data driving circuit 320 cannot be written into the pixel 10. In this way, the power consumption of the display panel 100 can be further reduced while ensuring that the pixels 10 in the first display area AA1 can refresh the data signals and the pixels 10 in the second display area AA2 maintain the data signals written in the previous driving cycle unchanged.

[0077] Understandably, Fig. 9The technical solution of the embodiment of the present invention is described by taking the effective level of the refresh control signal and the gate drive signal as a low level and the invalid level as a high level as an example. In the embodiment of the present invention, the effective level and the invalid level of the refresh control signal and the gate drive signal can be designed according to actual needs. For example, when the device controlled by the refresh control signal Ctrl in the gate drive circuit 40 includes a P-type transistor, the effective level of the refresh control signal Ctrl is a low level and the invalid level is a high level; and when the device controlled by the refresh control signal Ctrl in the gate drive circuit 40 includes an N-type transistor, the effective level of the refresh control signal Ctrl is a high level and the invalid level is a low level. Similarly, when the device controlled by the gate drive signal Gout in the pixel 10 includes a P-type transistor, the effective level of the gate drive signal Gout is a low level and the invalid level is a high level; and when the device controlled by the gate drive signal Gout in the pixel 10 includes an N-type transistor, the effective level of the gate drive signal Gout is a high level and the invalid level is a low level. For the convenience of description, under the premise of no special limitation, the embodiments of the present invention all take the effective level as a low level and the invalid level as a high level as an example to exemplarily illustrate the technical solutions of the embodiments of the present invention.

[0078] Optionally, based on the above embodiment, Fig.10 is another driving timing diagram of a display panel provided by an embodiment of the present invention. Figure 5 and Fig.10 , the driving method of the display panel further includes: acquiring grayscale data of the display panel 100 in real time; the grayscale data includes the grayscale of each pixel 10; outputting a first data output control signal TE according to the time when the grayscale data is acquired; and outputting a second data output control signal TE2 according to the first data output control signal TE and the refresh control signal Ctrl. According to the second data output control signal TE2, the thrust of the data signal provided to each pixel 10 is controlled.

[0079] It is understandable that the grayscale of the pixel 10 can be the brightness level of the pixel 10 displaying light, and different grayscales can correspond to different display light brightness levels, and the higher the grayscale, the higher the display light brightness. By controlling the display light brightness of pixels 10 of different colors, the display panel 100 can present a colorful display screen.

[0080] It can also be understood that the driving chip 30 can include at least two data output control signal ports, one of which can output the first data output control signal TE, and the other can output the second data output control signal TE2, through which the first data output control signal TE and the second data output control signal TE2 can be detected.

[0081] Specifically, the driver chip 30 can periodically obtain the grayscale data of the current screen display frame of the display panel 100 from the system mainboard, and parse the grayscale data to obtain the data signal corresponding to each pixel 10. At this time, the driver chip 10 can generate a first data output control signal TE according to the period of obtaining the grayscale data, so that the first data output control signal TE changes periodically according to the period of obtaining the grayscale data by the driver chip 10, so that the driver chip can output the first data output control signal TE that changes periodically. The first data output control signal TE can control the grayscale parsing circuit in the driver chip 30 to parse the grayscale data, and after obtaining the data signal of each pixel 10, the data signal of each row of pixels 10 is sequentially written into the data register 330, and provided by the data register 330 to the data driving circuit 320, so that the data driving circuit 320 can output the data signal of each row of pixels 10 accordingly.

[0082] At the same time, after the driving chip 30 generates the first data output control signal TE, it can also generate the second data output control signal TE2 according to the first data output control signal TE and the refresh control signal Ctrl. The second data output control signal TE2 can control the thrust gear of the thrust adjustment circuit 310, so that the thrust adjustment circuit 310 controls the thrust size of the data signal output by the data driving circuit 320 according to the thrust gear. In this way, when the data driving circuit 320 provides the data signal of the pixel 10 in the data writing frame, for example, in the T1 time period, the second data output control signal TE2 can control the thrust gear of the thrust adjustment circuit 310 to be the first preset gear, so that the thrust adjustment circuit 310 controls the data driving circuit 320 to provide the data signal to the pixel 10 with the first preset thrust according to the first preset gear; and when the data driving circuit 320 provides the data signal of the pixel 10 in the holding frame, for example, in the T2 time period, the second data output control signal TE2 can control the thrust gear of the thrust adjustment circuit 310 to be the second preset gear, so that the thrust adjustment circuit 310 controls the data driving circuit 320 to provide the data signal to the pixel 10 with the second preset thrust according to the second preset gear. In this way, by controlling the thrust adjustment circuit 310 to adjust the thrust of the data signal output by the data driving circuit 320 through the second data output control signal, the display effect of the display panel can be improved while reducing the display power consumption of the display panel.

[0083] In an optional embodiment, Fig.11 The present invention provides another driving timing diagram of a display panel, referring to Figure 5 and Fig.10 , outputting the first data output control signal according to the time when the grayscale data is acquired, including: outputting the valid level of the first data output control signal TE in the time period Tb of receiving the grayscale data; and outputting the invalid level of the first data output control signal TE in the grayscale data holding time period Ta.

[0084] Exemplarily, in the time period T10 in which each pixel 10 in the display panel 100 writes data signals at a refresh frequency f1, the period at which the driver chip 30 obtains grayscale data from the system mainboard can be 1 / f1, so that the first data output control signal TE can change periodically with 1 / f1, and in the interval between two grayscale data acquisitions, the grayscale data obtained by the driver chip 30 will remain unchanged, so that the first data output control signal TE will remain at an invalid level; and when the driver chip 30 starts to obtain grayscale data from the system mainboard, the grayscale data in the driver chip 30 starts to be updated, so that the first data output control signal TE will jump to a valid level.

[0085] In the display panel, during the time period T20 in which the pixels 10 in the first display area AA1 write data signals at a refresh frequency of f1 and the pixels 10 in the second display area AA2 write data signals at a refresh frequency of f2, the period of the driver chip 30 obtaining grayscale data from the system mainboard can be 1 / f2, so that the first data output control signal TE can be periodically changed by 1 / f2, that is, the pixels 10 in the first display area AA1 and the pixels 10 in the second display area AA2 are both in the time period TD of the data writing frame, and the driver chip 30 obtains grayscale data from the system mainboard, so that the first output control signal TE will jump to a valid level when the grayscale data is obtained; and when at least one of the pixels 10 in the first display area AA1 and the pixels 10 in the second display area AA2 is in the time period TH of maintaining the frame, the driver chip 30 will stop obtaining grayscale data from the system mainboard, so that the first output control signal TE will continue to remain at an invalid level.

[0086] Optionally, based on the above embodiment, continue to refer to Figure 5 and Fig.11, outputting the second data output control signal TE2 according to the first data output control signal TE and the refresh control signal Ctrl, including: when at least one of the first data output control signal TE and the refresh control signal Ctrl is at a valid level, outputting the valid level of the second data output control signal TE2; when the first data output control signal TE and the refresh control signal Ctrl are both at invalid levels, outputting the invalid level of the second data output control signal TE2; wherein, when the second data output control signal TE2 is at a valid level, providing a data signal with a first preset thrust to the display panel 100; when the second data output control signal TE2 is at an invalid level, providing a data signal with a second preset thrust to the display panel 100, and the first preset thrust is greater than the second preset thrust. In this way, when at least one of the first data output control signal TE and the refresh control signal Ctrl is at an invalid level, the second data output control signal TE2 generated by the driver chip 30 is at an invalid level. At this time, the thrust adjustment circuit 310 can be used to control the data driver circuit 320 to output the data signal with the second preset thrust; and when the first data output control signal TE and the refresh control signal Ctrl are both at valid levels, the thrust adjustment circuit 310 can be used to control the data driver circuit 320 to output the data signal with the first preset thrust, thereby meeting the demand for refreshing the data signal of the pixels 10 in the display area with a higher refresh frequency, while being beneficial to low power consumption of the display panel 100 and the driver chip 30.

[0087] Optional, continue to refer to Figure 5 and Fig.11 , during a portion of the display time in the current driving mode, a data signal having a first preset thrust is provided to each pixel 10 .

[0088] The first preset thrust may be a relatively large thrust, or the first preset thrust may be a relatively small thrust. It may be specifically designed according to the actual display requirements of the display panel 100 , and the embodiment of the present invention does not specifically limit this.

[0089] Specifically, taking the current driving mode in which the display panel includes a first display area AA1 with a higher refresh rate and a second display area AA2 with a lower refresh rate as an example, if part of the display time in the current driving mode is a time period in which both the pixels 10 of the first display area AA1 and the pixels 10 of the second display area AA2 are in a data writing frame, then within the time period, the data signal provided by the data driving circuit 320 needs to be written into each pixel 10 one by one. At this time, the thrust adjustment circuit 310 can control the data driving circuit 320 to output the data signal of each pixel 10 in the first display area AA1 with the first preset thrust, and output the data signal of each pixel 10 in the second display area AA2 with the first preset thrust, that is, the data driving circuit 320 outputs the data signal of each pixel 10 with a larger thrust, thereby ensuring that both the first display area AA1 and the second display area AA2 can complete fast charging, and at the same time, the data signal writing conditions of the display area with a higher refresh rate and the display area with a lower refresh rate are kept consistent, thereby improving the display uniformity of the display panel.

[0090] Alternatively, if part of the display time in the current driving mode is a time period in which both the pixels 10 of the first display area AA1 and the pixels 10 of the second display area AA2 are in a frame holding period, then during this time period, there is no need to write the data signal provided by the data driving circuit 320 into each pixel 10. At this time, the thrust adjustment circuit 310 can control the data driving circuit 320 to output the data signal of each pixel 10 in the first display area AA1 with the first preset thrust, and output the data signal of each pixel 10 in the second display area AA2 with the first preset thrust, that is, the data driving circuit 320 outputs the data signal of each pixel 10 with a smaller thrust, thereby ensuring that the data driving circuit 320 can have a smaller power consumption, which is beneficial to reduce the overall power consumption of the driving chip 30 and the display panel 100.

[0091] Optionally, based on the above implementation, continue to refer to Figure 5 and Fig.11 The display panel 100 includes a plurality of frame periods T3; the time period between two adjacent frame periods T3 is a blanking stage T4; the driving method of the display panel further includes: in the blanking stage T4, controlling the data driving circuit 320 to provide a data signal having a third preset thrust to each pixel 10 respectively; wherein the third preset thrust is less than or equal to the second preset thrust.

[0092] It can be understood that the blanking period T4 can be a vertical blanking stage, that is, a field blanking stage, which refers to the period from the end of the data writing stage of the last row of pixels 10 in the display panel 100 to the beginning of the data writing stage of the first row of pixels 10, which is between two adjacent frame periods T3. During the blanking period, the picture displayed by the display panel 100 can remain unchanged, and the data signal written to each pixel 10 in the display panel 100 can remain unchanged, so that the data signal provided by the data driving circuit 320 does not need to be written into each pixel 10 during this period.

[0093] Specifically, since there is no need to write data signals to each pixel 10 in the blanking stage, the thrust adjustment circuit 310 can be used to control the data driving circuit 320 to provide each pixel 10 with a data signal of a third preset thrust, and the third preset thrust is less than or equal to the second preset thrust, that is, when the thrust value of the second preset thrust is 0, the thrust value of the third preset thrust can also be 0, or, when the thrust value of the second preset thrust is greater than 0, the thrust value of the third preset thrust can still be maintained at 0, so that in the blanking stage T4, the data driving circuit 320 can output the data signal with a smaller thrust, which is beneficial to reduce the power consumption of the data driving circuit 320 and reduce the power consumption of the display panel 100.
