Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
As described in the background art, the display panel includes a plurality of pixels, specifically, a plurality of sub-pixels, and includes pixel circuits corresponding to the sub-pixels, and a plurality of signal lines such as data lines and scan lines connected to the pixel circuits. Parasitic capacitance exists between the data line and other metal film layers overlapped with the data line (for example, other signal lines overlapped with the data line), when the display panel is driven, the storage capacitance in the pixel circuit corresponding to all sub-pixels in the whole display panel usually needs to be charged and discharged in each frame, and the process of charging the storage capacitance usually is the process of writing data voltage into the storage capacitance by the driving chip through the data line, so that when the storage capacitance is charged, the parasitic capacitance formed by the data line and other metal film layers can be charged, much electric quantity is consumed on the parasitic capacitance, and unnecessary electric quantity consumption is caused; particularly, when the display panel is driven at a high frequency, the frequency of charging and discharging the storage capacitor is high, and correspondingly, the frequency of charging and discharging the parasitic capacitor is also high, so that the electric quantity consumed on the parasitic capacitor is large, and finally, the driving power consumption of the display panel is large.
In view of the above problem, an embodiment of the present invention provides a display panel, and fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention, and referring to fig. 1, the display panel 100 includes a display area 110 and a non-display area 120, the display area 110 includes a sub-pixel array and a plurality of data lines (D1, D2, D3, D4, D5, D6 … …), the sub-pixel array includes a plurality of sub-pixels 111, and each sub-pixel 111 is electrically connected to one data line; the sub-pixel array is divided into at least two sub-pixel areas; in the same column of sub-pixels of the sub-pixel array, the data lines electrically connected with the sub-pixels positioned in different sub-pixel areas are different, and the sub-pixels positioned in the same sub-pixel area are electrically connected with at least one data line;
the scanning frequencies of the scanning units of the sub-pixel rows corresponding to at least two sub-pixel areas are different.
Specifically, the display area 110 is an area where the display panel can display a picture, and the non-display area 120 is an area where the display panel does not display the picture, referring to fig. 1, fig. 1 schematically shows a display panel structure where the non-display area 120 surrounds the display area 110, it should be noted that the positional relationship between the non-display area 120 and the display area 110 is not limited to that the non-display area 120 surrounds the display area 110 shown in fig. 1, and may also be that the display area 110 surrounds the non-display area 120 (for example, a full-screen display panel, where the non-display area 120 includes only an area corresponding to a camera, and at this time, the display area 110 is disposed around the non-display area 120), and may also be a positional relationship between the display area 110 and the non-display area 120 that any display panel in the prior art has.
The sub-pixel array in the display area 110 is used for displaying a display image, and the sub-pixel array includes a plurality of sub-pixels, and the plurality of sub-pixels 111 may be arranged in an array. The embodiment of the present invention does not limit the type of the display panel, for example, the display panel may be an organic light emitting display panel, and each sub-pixel may include an organic light emitting device; the display panel may also be a Micro light emitting diode (Micro LED) display panel, in which case each sub-pixel may include a Micro LED. The display panel further includes pixel circuits corresponding to the sub-pixels, and each of the pixel circuits includes a storage capacitor, and each of the storage capacitors is generally electrically connected to a data line in the display panel, directly or indirectly, so that a data voltage transmitted by the data line can be written into the storage capacitor. It should be noted that, in the embodiment of the present invention, each data line includes the first portion 11 extending along the Y direction and the second portion 12 connecting the first portion and each pixel, that is, each pixel corresponds to the second portion 12 of one data line, and optionally, the second portion 12 is disposed along the X direction.
Specifically, when the display panel performs display, the display frame in a part of the area may be refreshed faster, and the display frame in a part of the area may be refreshed slower, in which case the scanning frequencies corresponding to different areas may be different. In the conventional display panel, the whole display panel usually corresponds to only one scanning frequency, each row of pixels is connected with one data line, and when data voltage is written into each sub-pixel, the data voltage is transmitted through the first portion 11 of the data line electrically connected to the sub-pixel and the respective second portion 12 of the data line electrically connected to the sub-pixel, as described in the background art, parasitic capacitance exists between the data line and other metal layers overlapping the data line, that is, parasitic capacitance may exist between the first portion 11 and the second portion 12 of each data line and other metal layers, and when the storage capacitance in the pixel circuit corresponding to each sub-pixel is charged and discharged, the parasitic capacitance formed by the data line (including the first portion 11 and the plurality of second portions 12) and other metal layers electrically connected to the sub-pixel is charged and discharged once, resulting in a large power loss.
In the embodiment of the present invention, the sub-pixel array is divided into at least two sub-pixel regions, and the scanning frequencies of the at least two sub-pixel regions in the scanning unit are different, referring to fig. 1, fig. 1 schematically illustrates a case where the sub-pixel array is divided into two sub-pixel regions, which are respectively referred to as a first sub-pixel region 130 and a second sub-pixel region 140, and the following description will be made of a case where the sub-pixel array shown in fig. 1 is divided into two sub-pixel regions. Fig. 2 is a schematic diagram of sub-pixel region division of a display panel according to an embodiment of the present invention, the schematic diagram of sub-pixel region division shown in fig. 2 corresponds to a structural schematic diagram of the display panel shown in fig. 1, and referring to fig. 1 and fig. 2, exemplarily, the first sub-pixel region 130 corresponds to a relatively low scanning frequency, and the second sub-pixel region 140 corresponds to a relatively high scanning frequency, and accordingly, within the same time, the number of times of image refreshing displayed in the first sub-pixel region 130 is small, and the number of times of image refreshing displayed in the second sub-pixel region 140 is large. In the same-column sub-pixels, taking the sub-pixels in the leftmost column in fig. 1 as an example, the sub-pixels in the first sub-pixel region 130 are connected to the data line D1, the sub-pixels in the second sub-pixel region 140 are connected to the data line D2, and the sub-pixels in the first sub-pixel region 130 and the second sub-pixel region 140 are connected to different data lines in the same column, so that data can be written only to the sub-pixels in the second sub-pixel region 140 having a high scanning frequency in one frame, that is, the storage capacitors of the pixel circuits corresponding to the sub-pixels in the second sub-pixel region 140 are charged and discharged, the storage capacitors of the pixel circuits corresponding to the sub-pixels in the first sub-pixel region 130 are not charged and discharged, that is, the data voltage is not input to the data lines electrically connected to the sub-pixels in the first sub-pixel region 130, and the data lines electrically connected to the sub-pixels in the second sub-pixel region 140 are connected only to the first portion 11 and the second portion 12 and the other film layer 12 of the data lines electrically connected to the sub-pixels in the second sub-pixel region 140 in one frame The formed parasitic capacitance is charged and discharged without charging and discharging the parasitic capacitance formed between the first portion 11 and the second portion 12 of the data line electrically connected to the sub-pixel in the first sub-pixel region 130 and other film layers, thereby reducing power loss caused by frequent charging and discharging of the parasitic capacitance formed between the data line electrically connected to the sub-pixel in the first sub-pixel region 130 and other film layers and reducing driving power consumption of the display panel.
In addition, since the parasitic capacitances between the first portions 11 of the data lines connected to the subpixels in the first subpixel region 130 and the subpixels in the second subpixel region 140 and other films are almost the same for one column of subpixels, when a data voltage is written only to a certain subpixel region in one frame, power loss due to charging and discharging of the parasitic capacitances between the second portions 12 of the data lines connected to the subpixels where no data voltage is written and other films can be reduced.
It should be noted that, when the display frames of all the sub-pixel regions in the display panel need to be changed in a certain frame, the storage capacitors corresponding to the sub-pixels in all the sub-pixel regions may also be charged and discharged in a certain frame. Fig. 3 is a timing diagram of data signals transmitted by data lines in the display panel according to the embodiment of the invention, where the timing diagram corresponds to the data signals transmitted by the data lines D1 and D2 electrically connected to the leftmost column of sub-pixels in the display panel shown in fig. 1. Only data corresponding to 4 frames (t1, t2, t3, t4) of display screen are schematically shown in fig. 3. Referring to fig. 1, 2 and 3, after the data line D1 transmits a data signal to the first sub-pixel region 130 corresponding to the low frequency region in the first frame t1 and the third frame t3, the data line D2 transmits a data signal to the second sub-pixel region 140 corresponding to the high frequency region; in the second frame t2 and the fourth frame t4, only the data line D2 transmits a data signal to the second subpixel region 140 corresponding to the high frequency region; it is possible to eliminate power loss caused by charging and discharging of parasitic capacitance formed between the data line electrically connected to the sub-pixel in the first sub-pixel region 130 and other film layers when data is written to the sub-pixel in the second sub-pixel region 140 in the second frame t2 and the fourth frame t 4.
It should be further noted that fig. 1 schematically illustrates that, in a column of sub-pixels, sub-pixels located in the first sub-pixel region 130 and the second sub-pixel region 140 are respectively connected to one data line, and in a column of sub-pixels, sub-pixels located in the same sub-pixel region may also be connected to two or more data lines, which is not specifically limited herein in the embodiment of the present invention.
According to the display panel provided by the embodiment of the invention, the sub-pixel array in the display area is divided into at least two sub-pixel areas; in the same column of sub-pixels of the sub-pixel array, the data lines electrically connected with the sub-pixels positioned in different sub-pixel areas are different, and the sub-pixels positioned in the same sub-pixel area are electrically connected with at least one data line; the scanning frequencies of the scanning units of the sub-pixel rows corresponding to the at least two sub-pixel areas are different; the refresh rate of the display frame in different sub-pixel regions of the display panel can be different, and when different sub-pixel regions are scanned at different scanning frequencies, data voltage can be written into the storage capacitor in the pixel circuit in a sub-pixel region with a higher partial scanning frequency in one frame, so that the charging and discharging frequency of the parasitic capacitor between the data line electrically connected with the sub-pixel in the sub-pixel region with a lower scanning frequency and other film layers is lower, the electric quantity loss caused by frequent charging and discharging of the parasitic capacitor between the data line and other film layers is reduced, and finally the driving power consumption of the whole display panel is reduced.
With reference to fig. 1, based on the above technical solution, optionally, the same column of sub-pixels located in the same sub-pixel region are electrically connected to the same data line, and taking the leftmost column of sub-pixels in fig. 1 as an example, the sub-pixels located in the first sub-pixel region 130 are all electrically connected to the data line D1, and the sub-pixels located in the second sub-pixel region 140 are all electrically connected to the data line D2, so that on the basis of reducing power loss caused by frequent charging and discharging of parasitic capacitance, it is ensured that the number of data lines in the display panel is not greatly increased, which is beneficial to reducing wiring difficulty and ensuring aperture ratio.
Fig. 4 is a schematic structural diagram of another display panel according to an embodiment of the present invention, and referring to fig. 4, on the basis of the above technical solution, optionally, at least two sub-pixel regions are a first sub-pixel region 130 and a second sub-pixel region 140, where the first sub-pixel region 130 corresponds to a first scanning frequency and the second sub-pixel region 140 corresponds to a second scanning frequency;
in the same column of sub-pixels, the sub-pixels in the first sub-pixel region 130 are electrically connected to one data line, and the sub-pixels in the second sub-pixel region 140 are electrically connected to at least two data lines; wherein the first scanning frequency is less than the second scanning frequency.
Fig. 4 schematically illustrates a case where the sub-pixels in the second sub-pixel region 140 are electrically connected to two data lines, and the following description is made of a case where the sub-pixels in the second sub-pixel region 140 illustrated in fig. 4 are electrically connected to two data lines, for example, for the sub-pixels in the first column in fig. 3, the sub-pixels located in the first sub-pixel region 130 are electrically connected to the data line D1, and a part of the pixels located in the second sub-pixel region 140 are electrically connected to the data line D21, and the other part is electrically connected to the data line D22. When the storage capacitor in the pixel circuit corresponding to each sub-pixel is charged, the data voltage is transmitted through the data line electrically connected to the sub-pixel, and the transmitted data voltage passes through the first portion 11 and each second portion 12 of the data line, and accordingly, the parasitic capacitors formed by the first portion 11 and each second portion 12 and other film layers are charged. The sub-pixels located in the second sub-pixel region 140 are connected to at least two data lines, so that the data lines electrically connected to each sub-pixel have a smaller number of second portions 12, and the number of parasitic capacitors formed between the corresponding second portions 12 and other film layers is smaller, so that when a data voltage is written to each sub-pixel in the second sub-pixel region 140, power loss caused by the parasitic capacitors is reduced. In addition, because the storage capacitor in the pixel circuit corresponding to the sub-pixel in the sub-pixel region with higher scanning frequency is charged and discharged with higher frequency, correspondingly, the parasitic capacitor formed between the data line and other film layers is charged and discharged with higher frequency, therefore, the sub-pixel region with higher scanning frequency is connected with two or more data lines, so that the power loss caused by the parasitic capacitor is reduced when each sub-pixel is scanned, and the power loss caused by frequent charging and discharging of the parasitic capacitor is reduced.
With continued reference to fig. 1, based on the above scheme, different data lines connected to the same column of sub-pixels are optionally distributed on two opposite sides of the column of sub-pixels.
Specifically, for example, for the leftmost column of sub-pixels in the display panel shown in fig. 1, the data line D1 electrically connected to the sub-pixels in the first sub-pixel region 130 is located at the left side of the column of sub-pixels, the data line D2 electrically connected to the sub-pixels in the second sub-pixel region 140 is located at the right side of the column of sub-pixels, and different data lines connected to the same column of sub-pixels are distributed at two opposite sides of the column of sub-pixels, so that the mutual bridging of the data lines electrically connected to the same column of sub-pixels can be effectively reduced, further, the electric loss caused by the parasitic capacitance formed by the mutual bridging of the data lines is reduced, and the driving power consumption of the display panel is further reduced.
With continuing reference to fig. 1 and 4, based on the above technical solution, optionally, each sub-pixel region includes at least one row of sub-pixels.
Specifically, when the sub-pixel regions are divided, usually, according to the speed of change of the display image corresponding to each region in the sub-pixel array, the scanning frequency of the sub-pixel region with the fast change of the display image corresponding to the region is high, and the scanning frequency of the sub-pixel region with the slow change of the display image corresponding to the region is low, each sub-pixel region at least includes one row of sub-pixels, which can correspond to the scanning mode of scanning units by sub-pixel rows. Alternatively, the display panel provided by the present embodiment may be applied to wearable devices, for example, devices mounted on the head of the user, such as virtual reality and augmented reality devices, for example, only the region directly in front of the eyes of the user has a fast change in picture, a line or lines directly in front of the user's eyes can be divided into one sub-pixel area, the sub-pixels of the other rows are divided into other sub-pixel regions so that when the sub-pixel region right in front of the eye is scanned with high frequency and data is written to the storage capacitance in the pixel circuit corresponding to the sub-pixel in the sub-pixel region, the sub-pixels of the other sub-pixel region are not scanned and data is not written, and further, the charging and discharging loss generated by parasitic capacitance between the data line and other film layers in the sub-pixel regions except the sub-pixel region right in front of the eyes is reduced, and the driving power consumption of the display panel is reduced.
Fig. 5 is a schematic structural diagram of another display panel provided in an embodiment of the present invention, and referring to fig. 5, on the basis of the above scheme, optionally, the display panel further includes a driving chip 150 and a scan driving circuit 160, the scan driving circuit 160 is electrically connected to the driving chip 150, the scan driving circuit 160 includes a plurality of scan signal output terminals, each of the scan signal output terminals is connected to a row of sub-pixels through a scan line (S1, S2, S3, S4, S5, S6 … …); the driving chip 150 includes a plurality of data signal output terminals, each of which is connected to one of the data lines (D1, D2, D3, D4, D5, D6 … …).
Specifically, the scan driving circuit 160 may provide scan signals to each row of sub-pixels through a scan line, and the driving chip 150 may output data voltages to each sub-pixel through a data line. The scan driving circuit 160 is electrically connected to the driving chip 150, and the driving chip 150 can provide a trigger signal for the scan driving circuit 160, so that the scan driving circuit 160 starts to scan the sub-pixel array after receiving the trigger signal of the driving chip 150.
It should be noted that fig. 1-2 and fig. 4-5 only take the sub-pixel array in the display panel divided into the first sub-pixel region 130 and the second sub-pixel region 140 as an example for schematic illustration, the sub-pixel array can be further divided into more sub-pixel regions, fig. 6 is a schematic diagram of the sub-pixel region division of another display panel provided in the embodiment of the present invention, and referring to fig. 6, the sub-pixel array is divided into the sub-pixel regions 131 and 135, wherein for the sub-pixel regions with the same scanning frequency, for example, the sub-pixels in the same column in the sub-pixel regions 131 and the sub-pixel regions 135 can be connected to the same data line, or can be connected to different data lines.
Fig. 7 is a schematic structural diagram of another display panel according to an embodiment of the present invention, and referring to fig. 7, based on the above technical solution, optionally, the length of the data line electrically connected to the sub-pixel region closer to the driving chip 150 along the extending direction of the data line, i.e., the Y direction, is shorter.
The distance between the driving chip 150 and the sub-pixel region along the extending direction of the data line may be the distance between the driving chip 150 and the center of the sub-pixel region along the extending direction of the data line. Referring to fig. 7, fig. 7 also illustrates an example in which the sub-pixel array is divided into two sub-pixel regions, namely a first sub-pixel region 130 and a second sub-pixel region 140, wherein, in the extending direction of the data lines, i.e. the Y direction, the distance a between the second sub-pixel region 140 and the driving chip 150 is smaller than the distance b between the first sub-pixel region 130 and the driving chip 150, and accordingly, the length of the data lines (D2, D4, D6 … …) electrically connected to the second sub-pixel region 140 (specifically, the length of the first portion 11) is smaller than the length of the data lines (D1, D3, D5 … …) electrically connected to the first sub-pixel region 130 (specifically, the length of the first portion 11), for example, as shown in fig. 7, the first portion 11 of the data lines (D2, D4, D6 … …) electrically connected to the second sub-pixel region 140 only extends in the second sub-pixel region 140, and the data lines (D2) electrically connected to the second sub-pixel region 140 are not arranged in the first sub-pixel region 130, D4, D6 … …), the first portion 11 of the data line (D2, D4, D6 … …) electrically connected to the second subpixel region 140 has no parasitic capacitance with other film layers in the first subpixel region 130, and thus eliminates the power loss caused by frequent charging and discharging of the parasitic capacitance formed between the first portion 11 of the data line (D2, D4, D6 … …) electrically connected to the second subpixel region 140 and other film layers of the first subpixel region 130, thereby further reducing the driving power consumption of the display panel.
It should be noted that, for example, the positions of the data lines (D1, D3, D5 … …) electrically connected to the first sub-pixel region 130 in the first portion of the second sub-pixel region 140 may be adjusted accordingly to reduce the overlapping of the first portion 11 of the data line (D1, D3, D5 … …) electrically connected to the first sub-pixel region 130 with other metal film layers in the second sub-pixel region 140, so as to reduce the parasitic capacitance between the first portion 11 of the data line (D1, D3, D5 … …) electrically connected to the first sub-pixel region 130 and other film layers, thereby further reducing the power consumption of the display panel.
On the basis of the above technical solution, optionally, along the extending direction of the data line, the sub-pixel region corresponding to the highest scanning frequency is closest to the driving chip.
With reference to fig. 7, fig. 7 still takes the example that the sub-pixel array is divided into two sub-pixel regions, namely a first sub-pixel region 130 and a second sub-pixel region 140, as an example, wherein the scanning frequency corresponding to the second sub-pixel region 140 is higher than the scanning frequency corresponding to the first sub-pixel region 130. Specifically, since the sub-pixel region corresponding to the highest scanning frequency needs to be frequently charged and discharged, accordingly, the parasitic capacitance between the first portion 11 of the data line electrically connected to the sub-pixel corresponding to the highest scanning frequency and the metal film layer overlapping with the first portion 11 of the data line needs to be frequently charged and discharged, and the sub-pixel region corresponding to the highest scanning frequency is disposed closest to the driving chip 150, so that the length of the first portion 11 of the data line electrically connected to the sub-pixel region corresponding to the highest scanning frequency is shorter, thereby reducing the parasitic capacitance between the first portion 11 of the data line electrically connected to the sub-pixel region of the highest scanning frequency and the other film layers, and further reducing the power consumption on the parasitic capacitance between the first portion 11 of the data line electrically connected to the sub-pixel region of the highest scanning frequency and the other film layers when the sub-pixel region corresponding to the highest scanning frequency is charged and discharged, the driving power consumption of the display panel is further reduced.
Fig. 8 is a schematic structural diagram of another display panel according to an embodiment of the present invention, and referring to fig. 8, based on the foregoing solution, optionally, the sub-pixel array is divided into n sub-pixel regions, where n is greater than or equal to 2, and the scanning frequency corresponding to each sub-pixel region is different; the scan driving circuit 160 includes a plurality of scan driving units, which correspond to the sub-pixel regions one to one; each scan driving unit includes a plurality of shift registers 1611, and each shift register 1611 includes a trigger signal input terminal a and a scan signal output terminal B;
the trigger signal input end A of the first shift register in each scanning driving unit is electrically connected with the driving chip 150 through a trigger driving signal line, the trigger signal input end A of the mth shift register is electrically connected with the scanning signal output end B of the (m-1) th shift register, wherein m is more than or equal to 2.
The first shift register of each scan driving unit refers to the shift register closest to the upper edge 170 of the display panel when the display panel is placed as shown in fig. 6.
In fig. 8, the case where n is 2 is taken as an example to schematically illustrate, referring to fig. 8, the display panel includes two sub-pixel regions, namely a first sub-pixel region 130 and a second sub-pixel region 140, the scanning frequencies corresponding to the first sub-pixel region 130 and the second sub-pixel region 140 are different, correspondingly, the scanning driving circuit 160 includes two scanning driving units corresponding to the sub-pixel regions one to one, which are respectively denoted as a first scanning driving unit 161 and a second scanning driving unit 162, each scanning driving unit includes a plurality of shift registers 1611, and a scanning signal output end B of each shift register 1611 is connected to a row of sub-pixels through a scanning line, so as to output a scanning signal to each row of sub-pixels. In each scanning driving unit, starting from the second shift register, the trigger signal input end a of each shift register and the scanning signal output end B of the previous shift register, and the first shift register of each scanning driving unit is connected with the driving chip 150, and after the driving chip 150 outputs the trigger signal to the scanning driving unit, the scanning driving unit outputs the scanning signal to each row of sub-pixels electrically connected with the scanning driving unit row by row. Since the trigger signal input end a of the first shift register of each scan driving unit is electrically connected to the driving chip 150, the scan driving units are independent from each other, and thus, only the first sub-pixel region 130, or only the second sub-pixel region 140, or the second sub-pixel region 140 after scanning the first sub-pixel region 130 in the prior art, can be scanned. The driving chip 150 controls the scanning frequency of the sub-pixel region corresponding to each scanning driving unit by controlling the frequency of the trigger signal output to each scanning driving unit, and can realize charging only the storage capacitor in the sub-pixel region with higher scanning frequency in one frame by outputting the trigger signals with different frequencies to different sub-pixel regions, thereby reducing the electric quantity loss caused by frequent charging and discharging of the data line electrically connected with the sub-pixel in the sub-pixel region with lower scanning frequency and the parasitic capacitor formed by other film layers, and reducing the driving power consumption of the display panel.
Fig. 9 is a schematic structural diagram of another display panel according to an embodiment of the present invention, and referring to fig. 9, based on the above scheme, optionally, the sub-pixel array is divided into n sub-pixel regions, where n ≧ 2, where the n sub-pixel regions include at least two sub-pixel regions corresponding to the same scanning frequency; the scan driving circuit 160 includes a plurality of scan driving units, which correspond to the sub-pixel regions one to one; each scan driving unit includes a plurality of shift registers 1611, and each shift register 1611 includes a trigger signal input terminal a and a scan signal output terminal B;
the trigger signal input end A of the first shift register in the first scanning driving unit in the scanning driving unit corresponding to the sub-pixel region corresponding to the same scanning frequency is electrically connected with the driving chip 150 through trigger driving signal lines (E1, E2 … …), the trigger signal input end A of the first shift register in the jth scanning driving unit in the scanning driving unit corresponding to the sub-pixel region corresponding to the same scanning frequency is electrically connected with the scanning signal output end B of the last shift register of the jth-1 scanning driving unit, and j is more than or equal to 2; in the same scanning driving unit, a trigger signal input end A of the mth shift register is electrically connected with a scanning signal output end B of the (m-1) th shift register, wherein m is more than or equal to 2.
Fig. 9 schematically illustrates a case where the sub-pixel array is divided into three sub-pixel regions, namely, a first sub-pixel region 130, a second sub-pixel region 140 and a third sub-pixel region 180, and it is exemplified below that the sub-pixel array shown in fig. 9 is divided into a first sub-pixel region 130, a second sub-pixel region 140 and a third sub-pixel region 180, and the scan driving circuit 160 includes a first scan driving unit 161, a second scan driving unit 162 and a third scan driving unit 163 corresponding to the three sub-pixel regions, respectively, wherein the scan frequencies corresponding to the first sub-pixel region 130 and the third sub-pixel region 180 are the same, and the scan frequencies corresponding to the first sub-pixel region 130 and the second sub-pixel region 140 are different. Referring to fig. 9, the trigger signal input terminal a of the first shift register of the third scan driving unit 163 is electrically connected to the scan signal output terminal B of the last shift register of the first scan driving unit 161, so that in one frame, after the last row of sub-pixels of the first sub-pixel region 130 is scanned, the sub-pixels of the third sub-pixel region 180 start to be scanned, and the scanning frequencies of the first sub-pixel region 130 and the third sub-pixel region 180 are kept consistent. For example, when the scanning frequency corresponding to the first sub-pixel region 130 and the third sub-pixel region 180 is greater than the scanning frequency corresponding to the second sub-pixel region 140, after the scanning of the first sub-pixel region 130 is completed in one frame, the second sub-pixel region 140 may be skipped to directly scan the third sub-pixel region 180, so that only the storage capacitor in the sub-pixel region with the higher scanning frequency may be charged in one frame, and further, the power loss caused by frequent charging and discharging of the data line electrically connected to the sub-pixel in the sub-pixel region with the lower scanning frequency and the parasitic capacitor formed by other film layers is reduced, and the driving power consumption of the display panel is reduced.
Fig. 10 is a flowchart of a driving method of a display panel according to an embodiment of the present invention, where the driving method can be used to drive the display panel according to any of the above embodiments of the present invention, and referring to fig. 10 in conjunction with fig. 1, the display panel includes a display area 110 and a non-display area 120, the display area 110 includes a sub-pixel array and a plurality of data lines, the sub-pixel array includes a plurality of sub-pixels, and each sub-pixel is electrically connected to one data line; the sub-pixel array is divided into at least two sub-pixel areas; in the same column of sub-pixels of the sub-pixel array, the data lines electrically connected with the sub-pixels positioned in different sub-pixel areas are different, and the sub-pixels positioned in the same sub-pixel area are electrically connected with at least one data line;
the driving method comprises the following steps:
Specifically, the sub-pixel array includes at least two sub-pixel regions, and the scanning frequencies corresponding to the at least two sub-pixel regions are different in all the sub-pixel regions.

In at least another frame, the sub-pixels in at least two sub-pixel regions of the sub-pixel array all receive data signals (for example, refer to the case of the first frame t1 and the third frame t3 in fig. 3), so that when the display frames corresponding to all the sub-pixel regions in a certain frame are changed, all the pixels in the display panel can be scanned in a frame, and data is written into all the pixels, thereby ensuring normal display of the display frames.
It should be noted that, in a certain frame, there may be a sub-pixel region with a low scanning frequency where the display screen is changed, and a sub-pixel region with a high scanning frequency where the display screen is not changed, so that the frame may only scan the sub-pixel with a low scanning frequency but not scan the sub-pixel region with a high scanning frequency, and accordingly, the power loss caused by frequent charging and discharging of the parasitic capacitance formed by the data line electrically connected to the sub-pixel in the sub-pixel region with a high scanning frequency and the other film layers may be reduced in the frame.
In the driving method of the display panel provided by the embodiment of the invention, in a frame, a data signal is input to a sub-pixel in a preset sub-pixel region through a data line, and when the data line inputs the data signal to one sub-pixel region, the data line connected with the sub-pixels in other sub-pixel regions does not input the data signal; in at least one frame, the sub-pixels in at least one sub-pixel region do not receive data signals, so that when different sub-pixel regions are scanned at different scanning frequencies, data voltages can be written into the storage capacitors in the pixel circuits in a part of sub-pixel regions with higher scanning frequencies in one frame, the charging and discharging frequencies of parasitic capacitors between data lines electrically connected with the sub-pixels in the sub-pixel regions with lower scanning frequencies and other film layers are lower, the electric quantity loss caused by frequent charging and discharging of the parasitic capacitors between the data lines and the other film layers is reduced, and finally the driving power consumption of the whole display panel is reduced.

In at least one frame, the data signals are input to the sub-pixels in the sub-pixel region corresponding to the second scanning frequency only through the data lines, and the data signals are not input to the sub-pixels in the sub-pixel region corresponding to the first scanning frequency, so that when different sub-pixel regions are scanned at different scanning frequencies, the charging and discharging frequency of parasitic capacitance between the data lines electrically connected with the sub-pixels in the sub-pixel region with the lower scanning frequency and other film layers is lower, the electric quantity loss caused by frequent charging and discharging of the parasitic capacitance between the data lines and other film layers is reduced, and finally the driving power consumption of the whole display panel is reduced.
