Detailed Description

The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.

Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention. As shown in fig. 1, the display panel 100 includes a plurality of pixels 10 arranged in an array, and the plurality of pixels 10 arranged in the array includes a plurality of first pixels 11 and a plurality of second pixels 12; at least in the first direction, each first pixel 11 and each second pixel 12 are arranged at intervals. Taking the first direction as the column direction Y of the pixels 10, each first pixel 11 and each second pixel 12 are disposed at intervals along the first direction Y only as an example. The first pixels 11 and the second pixels 12 may be alternately arranged in the column direction Y such that the first pixels 11 are located in odd-numbered rows, the second pixels 12 are located in even-numbered rows, or the first pixels 11 are located in even-numbered rows and the second pixels 12 are located in odd-numbered rows.

Alternatively, as shown in fig. 2, when each first pixel 11 and each second pixel 12 are disposed at intervals only along the first direction, and the first direction is the row direction X of the pixels 10, the first pixels 11 and the second pixels 12 may be alternately disposed along the row direction X, that is, two adjacent first pixels 11 are separated by one second pixel 12, and two adjacent second pixels 12 are separated by one first pixel 11; at this time, the first pixels 11 may be located in odd columns and the second pixels 12 may be even columns; alternatively, the first pixels 11 are located in even columns and the second pixels 12 are located in odd columns.

Alternatively, as shown in fig. 3, the first pixels 11 and the second pixels 12 are not only arranged at intervals in the first direction but also arranged at intervals in the second direction; the first direction may be a row direction X of the pixels 10, the second direction may be a column direction Y of the pixels 10, or the first direction may be a column direction Y of the pixels 10, and the second direction may be a row direction X of the pixels 10.

It should be noted that fig. 1 to 3 are only exemplary drawings of the embodiments of the present invention, and fig. 1 to 3 only schematically illustrate that the first pixels 11 and the second pixels 12 may be alternately arranged in the row direction and/or the column direction, that is, two adjacent first pixels 11 are separated by one second pixel 12, and two adjacent second pixels 12 are separated by one first pixel 11; in the embodiment of the present invention, the number of the intervals between the first pixel and the second pixel may be set according to the actual situation, which is not particularly limited in the embodiment of the present invention. As illustrated in fig. 4, for example, in the column direction Y, two second pixels 12 are provided every two first pixels 11 at intervals, and two first pixels 11 are provided every two second pixels 12 at intervals; alternatively, as shown in fig. 5, in the row direction X, two second pixels 12 are provided every two first pixels 11 at intervals, and two first pixels 11 are provided every two second pixels 12 at intervals; alternatively, as shown in fig. 6, two second pixels 12 are provided for every two first pixels 11 at intervals in both the row direction X and the column direction Y, and two first pixels 11 are provided for every two second pixels 12 at intervals.

Fig. 7 is a flowchart of a driving method of a display panel according to an embodiment of the present invention. As shown in fig. 1, the control method of the display panel includes:

s110, when the (i+1) -th frame display picture is pre-displayed, writing the data signals of the first pixels in the data signals of the (i+1) -th frame display picture into the first pixels in a one-to-one correspondence manner, keeping the data signals of the second pixels as the data signals of the (i) -th frame display picture, controlling the first pixels to display according to the data signals corresponding to the first pixels in the data signals of the (i+1) -th frame display picture, and controlling the second pixels to display according to the data signals corresponding to the second pixels in the data signals of the (i) -th frame display picture.

S120, when the (i+2) -th frame display picture is pre-displayed, writing the data signals of the second pixels in the data signals of the (i+2) -th frame display picture into the second pixels in a one-to-one correspondence manner, keeping the data signals of the first pixels as the data signals of the (i+1) -th frame display picture, controlling the second pixels to display according to the data signals corresponding to the second pixels in the data signals of the (i+2) -th frame display picture, and controlling the first pixels to display according to the data signals corresponding to the first pixels in the data signals of the (i+1) -th frame display picture; i is a positive integer.

The pre-displayed frame display picture is a picture to be displayed by the display panel, namely, the pre-displayed frame display picture is a next frame display picture of the current frame display picture which is being displayed. Usually, when displaying the current frame display, firstly acquiring the data signal of the next frame display of the pre-display; the data signals of each frame of display picture comprise data signals which are in one-to-one correspondence with each pixel in the display panel, when the corresponding data signals are written into the pixels of the display panel, the pixels can display light with corresponding colors and brightness, the light with corresponding colors and brightness displayed by each pixel of the display panel is combined into one frame of display picture, continuous multi-frame display pictures are combined into a display picture of the display panel, and the display picture can be a static picture or a dynamic picture, namely, the picture displayed by the display panel which is observed by human eyes is not a single frame of display picture, but is a combination of multi-frame display pictures.

Specifically, the display panel shown in fig. 1 is taken as an example. As shown in fig. 1, when the i+1th frame display screen is pre-displayed, the data signals corresponding to the first pixels 11 of the display panel 100 are written into the first pixels 11 of the display panel 100 in a one-to-one correspondence manner, and the second pixels 12 of the display panel are kept as the data signals in the i frame display screen, that is, during the period of displaying the i frame display screen, the data signals of the i+1th frame display screen are inserted into the partial pixels (the first pixels 11) in the display panel 100, so that the partial pixels (the first pixels 11) can be displayed according to the data signals in the i+1th frame display screen, and the partial pixels (the second pixels 12) can continue to be displayed according to the data signals in the i frame display screen, so that the partial interior of the i+1th frame display screen can be displayed in advance during the display period of the i frame display screen, so that the content of the i+1th frame display screen can be seen in advance when the displayed image of the display panel 100 is viewed by human eyes; similarly, when the i+2 frame display screen is pre-displayed, the data signals corresponding to the second pixels 12 of the display panel 100 in the data signals of the i+2 frame display screen are written into the second pixels 12 of the display panel 100 in a one-to-one correspondence, and the first pixels 11 of the display panel 100 are kept as the data signals in the i+1 frame display screen, so that the partial pixels (the second pixels 12) can display according to the data signals in the i+2 frame display screen, and the partial pixels (the first pixels 11) can continue to display according to the data signals in the i+1 frame display screen, so that the display duration of the i+1 frame display screen is ensured, and meanwhile, the partial pixels (the second pixels 12) in the display panel 100 are inserted into the data signals of the i+2 frame display screen, thereby enabling the partial interior of the i+2 frame display screen to be displayed in advance, so that the human eyes can see the content of the i+2 frame display screen in advance when the displayed image of the display panel 100 is viewed.

In this way, in a specific application scenario, for example, a user is using a hand-tour application, when a part of data signals of a next frame of display picture are inserted in the display period of each frame of display picture, and the holding time of each frame of display picture can be kept unchanged, the user can see the display content of the next frame of display picture in advance on the premise of ensuring the smoothness and continuity of the display picture, so that the user experience can be improved; meanwhile, since the processing speed required by the larger data processing amount is faster, the cost of a chip for processing data is higher, and the power consumption is larger, when the i+1th frame display picture is pre-displayed, only the data signal of the i+1th frame display picture is provided for each first pixel, the data signal corresponding to each second pixel in the data signal of the i+1th frame display picture is omitted, and when the i+2th frame display picture is pre-displayed, only the data signal of the i+2th frame display picture is provided for each second pixel, and the data signal corresponding to each second pixel in the data signal of the i+2th frame display picture is omitted, so that the data processing amount is reduced, and the power consumption and the cost are reduced; in addition, since the first pixel and the second pixel of the display panel are arranged at intervals, the data signals of each frame of display screen can be uniformly distributed in each pixel of the display panel, and the uniformity of the display screen displayed by the display panel can be improved.

Alternatively, the data signal of the i-th frame display may be different from the data signal of the i+1-th frame display, and the data signal of the i+1-th frame display may be the same as the data signal of the i+2-th frame display. In this way, when the i+1-th frame display screen is pre-displayed, only the data signal of the i+1-th frame display screen is supplied to each first pixel, and the data signal corresponding to each second pixel is discarded from among the data signals of the i+1-th frame display screen, and when the i+2-th frame display screen is pre-displayed, only the data signal of the i+2-th frame display screen is supplied to each second pixel, and the data signal corresponding to each first pixel is discarded from among the i+2-th frame display screen, but since the data signal of the i+1-th frame display screen is identical to the data signal of the i+2-th frame display screen, when the data signal corresponding to each second pixel in the data signal of the i+2-th frame display screen is written to each second pixel in a one-to-one correspondence manner, the data signal of each first pixel and the data signal of each second pixel are combined, the complete i+2-th frame display screen can be presented, and the display effect of the display panel with the material number can be ensured.

Optionally, the display panel further includes a plurality of scan signal lines and a plurality of data signal lines, the scan signal lines are used for transmitting scan signals to corresponding pixels, and the data signal lines are used for transmitting data signals to corresponding pixels, so that the corresponding pixels can display according to the received data signals. At this time, the connection modes of the scanning signal lines and the data signal lines with the respective pixels may be set according to the arrangement modes of the first pixels and the second pixels.

As shown in fig. 8, when the first direction is the column direction Y of the pixels and the first pixel 11 and the second pixel 12 are pixels located in different rows, the pixels 10 located in the same row share the scan signal line 20, and the pixels 10 located in the same column share the data signal line 30, and the scan signal line electrically connected to the first pixel 11 is the first scan signal line 21, and the scan signal line electrically connected to the second pixel 12 is the second scan signal line 22. Taking the example that the first pixels 11 and the second pixels 12 are alternately arranged along the column direction, if the first pixels 11 are located in the odd-numbered rows and the second pixels 12 are located in the even-numbered rows, the scanning signal lines electrically connected with the odd-numbered rows are the first scanning signal lines, and the scanning signal lines electrically connected with the even-numbered rows are the second scanning signal lines; when the second pixels 12 are located in the odd-numbered rows and the first pixels 11 are located in the even-numbered rows, the scanning signal lines electrically connected to the odd-numbered rows are the second scanning signal lines, and the scanning signal lines electrically connected to the even-numbered rows are the first scanning signal lines.

For example, as shown in fig. 9, when the first direction is the row direction X of the pixels, and the first pixel 11 and the second pixel 12 are pixels located in different columns, each pixel 10 located in the same column shares a scan signal line 20, and each pixel 10 located in the same row shares a data signal line 30, and the scan signal line electrically connected to the first pixel 11 is a first scan signal line 21, and the scan signal line electrically connected to the second pixel 12 is a second scan signal line 22. Taking the example that the first pixels 11 and the second pixels 12 are alternately arranged along the row direction, if the first pixels 11 are located in odd columns and the second pixels 12 are located in even columns, the scanning signal lines electrically connected with the odd columns are the first scanning signal lines, and the scanning signal lines electrically connected with the even columns are the second scanning signal lines; when the second pixels 12 are located in odd columns and the first pixels 11 are located in even columns, the scanning signal lines electrically connected to the odd columns are the second scanning signal lines, and the scanning signal lines electrically connected to the even columns are the first scanning signal lines.

For example, as shown in fig. 10, when the first pixels 11 and the second pixels 12 are arranged at intervals in the first direction and the second direction, and the first direction is the row direction X of the pixels 10 and the second direction Y is the column direction Y of the pixels 10, the pixels 10 located in the same column share the data signal line 30, the scanning signal line 20 includes the first scanning signal line 21 and the second scanning signal line 22, the first pixels 11 located in the same row share the first scanning signal line 21, and the second pixels 12 located in the same row share the second scanning signal line 22. Taking the example that the first pixels 11 and the second pixels 12 are alternately arranged in both the row direction and the column direction, the first pixels 11 may be located in odd columns of the odd rows and even columns of the even rows, and the second pixels 12 may be located in even columns of the odd rows and odd columns of the even rows; alternatively, the first pixels 11 may be located in even columns of the odd rows and odd columns of the even rows, and the second pixels 12 may be located in odd columns of the odd rows and even columns of the even rows. At this time, the first pixels 11 of two adjacent rows may share the first scanning signal line 21, and the second pixels 12 of two adjacent rows may share the second scanning signal line 22, so as to reduce the number of signal lines in the display panel, thereby improving the aperture ratio of the display panel and simplifying the structure of the display panel.

At this time, the data signals of the first pixels in the data signals of the i+1th frame display are written into the first pixels in one-to-one correspondence, and the data signals of the second pixels are held as the data signals of the i frame display specifically: the method comprises the steps of sequentially providing an enabling level of a scanning signal for each first scanning signal line, providing a non-enabling level of the scanning signal for each second scanning signal line, and providing a data signal for each data signal line so as to write data signals of each first pixel in data signals of an i+1st frame display picture into each first pixel in a one-to-one correspondence manner.

Specifically, the first direction is the column direction of the pixels, and the first pixels are located in the odd-numbered rows, and the second pixels are located in the even-numbered rows. As shown in fig. 8, when the display panel is a liquid crystal display panel, each pixel 10 of the display panel 100 includes at least one switching transistor (not shown), and the gate of the switching transistor of each pixel is electrically connected to the scan signal line 20, the first pole of the switching transistor of each pixel 10 is electrically connected to the data signal line 30, and the second pole of the switching transistor of each pixel 10 is electrically connected to the pixel electrode of the pixel 10. When the scan signal line 20 transmits an enable level of a scan signal, the enable level can control the first pole of the switching transistor to be conducted with the second pole thereof, so that a data signal transmitted by the data signal line 30 is written into a pixel electrode electrically connected with the second pole of the switching transistor, the pixel electrode can form an electric field with corresponding intensity with a common electrode thereof according to the written data signal to drive liquid crystal to twist to a corresponding position, and the brightness of light passing through the liquid crystal in the area where the pixel electrode is located is controlled, so that the pixel where the pixel electrode is located presents light with corresponding color and brightness.

Fig. 11 is a driving timing diagram of an i+1st frame display according to an embodiment of the present invention. Referring to fig. 8 and 11 in combination, when writing data signals corresponding to the first pixels 11 in the data signals of the i+1th frame display screen into the first pixels 11 in one-to-one correspondence, and discarding data signals corresponding to the second pixels in the i+1th frame display screen, by sequentially supplying the enable levels of the scanning signals (Gout 11, gout13, gout15, gout17, …) to the respective first scanning signal lines 21, the switching transistors of the respective first pixels 11 located in the odd-numbered rows are sequentially turned on, so that the data signals transmitted by the respective data signal lines 30 are written into the respective first pixels 11 in one-to-one correspondence through the turned-on switching transistors, so that the first pixels 11 can exhibit light of the corresponding colors and brightnesses according to the written data signals; and the non-enable level of the scanning signals (Gout 22, gout24, gout26, gout28 …) is supplied to the respective second scanning signal lines 22 such that the switching transistors of the respective second pixels 12 located at the even numbered rows are in the off state, the data signals transmitted by the respective data signal lines 30 are not written into the respective second pixels 12 such that the data signals of the second pixels 12 are not changed, i.e., the respective second pixels 12 are maintained as the data signals of their display pictures at the i-th frame.

In this way, during the period of displaying the i-th frame display screen, the data signal of the i+1th frame display screen is written into each first pixel, so that the i+1th frame display screen can be displayed in advance; meanwhile, the first pixel and the second pixel are electrically connected with different scanning signal lines, so that when the i+1th frame display picture is written into each first pixel, only the enabling level of the scanning signal is needed to be provided for the first scanning signal line, the number of the enabling levels of the provided scanning signal is reduced, the power consumption of the display panel is reduced, the time required for writing the data signal of the i+1th frame display picture is reduced, and the refresh frequency of the display panel is improved.

Correspondingly, the data signals of the second pixels in the data signals of the i+2 frame display picture are written into the second pixels in a one-to-one correspondence manner, and the data signals of the first pixels are kept as the data signals of the i+1 frame display picture, specifically: the enabling level of the scanning signal is provided for each second scanning signal line in turn, the disabling level of the scanning signal is provided for each first scanning signal line, and the data signal is provided for each data signal line, so that the data signals of each second pixel in the data signals of the i+2 frame display picture are written into each second pixel in a one-to-one correspondence manner.

Fig. 12 is a driving timing diagram of an i+2th frame display according to an embodiment of the present invention. Referring to fig. 8 and 12 in combination, when writing the data signals corresponding to the second pixels 12 in the data signals of the i+2 frame display screen into the second pixels 12 one by one and discarding the data signals corresponding to the first pixels in the i+2 frame display screen, the switching transistors of the second pixels 12 located in the even-numbered rows are sequentially turned on by sequentially supplying the enable levels of the scanning signals (Gout 22, gout24, gout26, gout28 …) to the second scanning signal lines 22, so that the data signals transmitted by the data signal lines 30 are written into the second pixels 12 one by one through the turned-on switching transistors, so that the second pixels 12 can exhibit light of the corresponding colors and brightness according to the written data signals; while the non-enable level of the scanning signals (Gout 11, gout13, gout15, gout17 …) is supplied to the respective first scanning signal lines 21 such that the switching transistors of the respective first pixels 11 located at the odd numbered rows are in the off state, the data signals transmitted by the respective data signal lines 30 are not written into the respective first pixels 11 such that the data signals of the first pixels 11 are not changed, i.e., the respective first pixels 11 are maintained as the data signals of their display screens at the i+1th frame.

In this way, the i+2th frame display screen can be displayed in advance; meanwhile, the number of the enabling levels of the provided scanning signals is reduced, so that the power consumption of the display panel is reduced, the time required for writing the data signals of the (i+2) th frame display picture is reduced, and the refresh frequency of the display panel can be improved.

Optionally, the display panel may further include a first scan driving circuit and a second scan driving circuit, where the first scan driving circuit may be located on the same side or different sides of each pixel, and when the first scan driving circuit and the second scan driving circuit are located on different sides of each pixel, the first scan driving circuit and the second scan driving circuit may be disposed opposite to each other. The output end of the first scanning driving circuit is electrically connected with the first scanning signal line, and the output end of the second scanning driving circuit is electrically connected with the second scanning signal line.

At this time, the enabling level of the scanning signal is sequentially supplied to each first scanning signal line, and the disabling level of the scanning signal is specifically: the output end of the first scanning driving circuit is controlled to sequentially output the enabling level of the scanning signal to each first scanning signal line, and the output end of the second scanning driving circuit is controlled to sequentially output the non-enabling level of the scanning signal to each second scanning signal line; the enabling level of the scanning signal is sequentially provided to each of the second scanning signal lines, and the disabling level of the scanning signal is provided to each of the first scanning signal lines specifically: the output end of the second scanning driving circuit is controlled to sequentially output scanning signals to each second scanning signal line, and the output end of the first scanning driving circuit is controlled to sequentially output non-enabling level of the scanning signals to each first scanning signal line.

Illustratively, the first pixels are located in odd rows and the second pixels are located in even rows. Fig. 13 is a schematic structural diagram of another display panel according to an embodiment of the present invention. As shown in fig. 13, the display panel 100 includes a first scan driving circuit 51 and a second scan driving circuit 52 disposed opposite to each other, wherein an output terminal of the first scan driving circuit 51 is electrically connected to the first scan signal line 21, and an output terminal of the second scan driving circuit 52 is electrically connected to the second scan signal line 22, that is, the first scan signal line 21 and the second scan signal line 22 are electrically connected to output terminals of different scan driving circuits (51, 52), respectively. Thus, when the data signal needs to be written into each first pixel 11, the first scan driving circuit 51 can be controlled to operate, so that the first scan driving circuit 51 can sequentially output the enable signal of the scan signal to each first scan signal line 21, and the second scan driving circuit 52 can be controlled to output the disable signal of the scan signal to each second scan signal line 22; when the data signal lines need to be written into the second pixels 12, the second scan driving circuit 52 can be controlled to operate, so that the second scan driving circuit 52 can sequentially output the enabling signals of the scan signals to the second scan signal lines 22, and the first scan driving circuit 51 is controlled to output the disabling signals of the scan signals to the first scan signals 21, so that no matter in the process of pre-displaying the i+1th frame display picture or the process of pre-displaying the i+2th frame display picture, only one of the scan driving circuits is controlled to operate, thereby being beneficial to simplifying the control mode of the display panel and reducing the power consumption of the display panel.

In the above description, the display panel is taken as an example of a liquid crystal display panel, and the writing of the data signals of the i+1st frame display screen and the i+2nd frame display screen is described as an example; in the embodiment of the present invention, the specific type of the display panel is not particularly limited.

For example, when the display panel is an organic light emitting display screen, each pixel of the display panel includes a pixel driving circuit and an organic light emitting element, and the pixel driving circuit is capable of driving the organic light emitting element to emit light. Each pixel driving circuit at least comprises a data writing transistor and a driving transistor, wherein a scanning signal transmitted by a scanning signal line can control the on or off of the data writing transistor, and when the data writing transistor is on, the data signal can be written into the grid electrode of the driving transistor, so that the driving transistor can generate driving current according to the data signal of the grid electrode of the driving transistor, and the organic light emitting element is driven to emit light with corresponding color and brightness. In this way, by sequentially supplying the first scanning signal line with the enable level of the scanning signal capable of turning on the data writing transistor of the first pixel and the second scanning signal line with the disable level controlling the data writing transistor of each second pixel to be in the off state, that is, when the i+1th frame display screen is pre-displayed, the data signals corresponding to the first pixels in the data signals of the i+1th frame display screen can be written to each first pixel in one-to-one correspondence, and each second pixel can be kept as the data signal in the i frame display screen; similarly, when the i+2 frame display screen is pre-displayed, the data signals corresponding to the second pixels in the data signals of the i+2 frame display screen can be written to the second pixels in a one-to-one correspondence, and the first pixels can be held as the data signals in the i+1 frame display screen.

In addition, the pixel driving circuit of each pixel may further include other transistors, so as to compensate the threshold voltage of the driving transistor, and prevent the threshold of the driving transistor from drifting due to the manufacturing process, aging and other reasons of the driving transistor, thereby affecting the light-emitting brightness of the organic light-emitting element.

Illustratively, the pixel driving circuit of each pixel is exemplified as a 7T1C pixel driving circuit.

The reset phase may be the same as the initialization phase or the data writing phase, so that the scan signal received by the reset transistor M4 is the same as the scan signal received by the initialization transistor M1 or the data writing transistor M2.

Alternatively, when each pixel includes a driving transistor and a light emitting element, the display panel may further include a light emission control signal line, and each pixel located in the same row shares the light emission control signal line or each pixel located in the same column shares the light emission control signal line.

At this time, when each first pixel 11 displays according to the data signal corresponding to the i+1th frame display screen, the light emission control signal may be transmitted to the corresponding first pixel 11 through the light emission control signal line 41, so that the light emission control transistors M5 and M6 of the first pixel 11 are turned on, and further the driving current generated by the driving transistor T of the first pixel 11 may flow into the organic light emitting element 120 of the first pixel 11, so that the organic light emitting element 120 of the first pixel 11 emits light; and when each second pixel 12 displays according to the data signal of the i-th frame display screen, the light-emitting control signal can be transmitted to the corresponding second pixel 12 through the light-emitting control signal line 42, so that the light-emitting control transistors M5 and M6 of the second pixel 12 are turned on, and further the driving current generated by the driving transistor T of the second pixel 12 can flow into the organic light-emitting element 120 of the second pixel 12, so that the organic light-emitting element 120 of the second pixel 12 emits light.

Correspondingly, the control of each second pixel to display according to the data signal corresponding to the second pixel in the data signal of the i+2 frame display picture, and the control of each first pixel to display according to the data signal corresponding to the first pixel in the data signal of the i+1 frame display picture are specifically as follows: providing a light-emitting control signal to each light-emitting control signal line, and when the light-emitting control signal line electrically connected with the second pixel receives the light-emitting control signal, providing a driving current to the light-emitting element of the second pixel by the driving transistor of the second pixel according to a data signal corresponding to the second pixel in the data signal of the (i+2) th frame display picture, and controlling the light-emitting element of the second pixel to emit light; and when the light-emitting control signal line electrically connected with the first pixel receives the light-emitting control signal, the driving transistor of the first pixel provides driving current to the light-emitting element of the first pixel according to the data signal corresponding to the first pixel in the ith frame display picture, and controls the light-emitting element of the first pixel to emit light.

Illustratively, the first pixels are also located in odd rows and the second pixels are located in even rows. As shown in fig. 13 and 14, when each second pixel 12 displays according to the data signal corresponding to the i+2th frame display screen, the light emission control signal is transmitted to the corresponding second pixel 12 through the light emission control signal line 42, so that the light emission control transistors M5 and M6 of the second pixel 12 are turned on, and further the driving current generated by the driving transistor T of the second pixel 12 can flow into the organic light emitting element 120 of the second pixel 12, so that the organic light emitting element 120 of the second pixel 12 emits light; and when each first pixel 11 displays according to the data signal of the i+1st frame display screen, the light-emitting control signal can be transmitted to the corresponding first pixel 11 through the light-emitting control signal line 41, so that the light-emitting control transistors M5 and M6 of the first pixel 11 are turned on, and further the driving current generated by the driving transistor T of the first pixel 11 can flow into the organic light-emitting element 120 of the first pixel 11, so that the organic light-emitting element 120 of the first pixel 11 emits light.

Optionally, when the display panel includes a light emission control signal line, the display panel should further include a light emission control circuit, and an output terminal of the light emission control circuit is electrically connected to the light emission control signal line. At this time, the supply of the light emission control signal to each light emission control signal line is specifically: the output end of the control light-emitting control circuit sequentially outputs light-emitting control signals to each light-emitting control signal line, so that each light-emitting control signal line can transmit corresponding light-emitting control signals to corresponding pixels, and driving currents generated by driving transistors of the pixels flow into organic light-emitting elements of the pixels, so that the organic light-emitting elements of pixels in each row can sequentially start to emit light.

Optionally, when the i+1th frame display screen is pre-displayed, the data signal of the i+1th frame display screen is also required to be acquired, and when the i+2th frame display screen is pre-displayed, the data signal of the i+2th frame display screen is also required to be acquired. Fig. 15 is a flowchart of a driving method of a display panel according to another embodiment of the present invention. As shown in fig. 5, the driving method of the display panel includes:

s210, acquiring a data signal of the (i+1) th frame display picture, and storing the data signal of the (i+1) th frame display picture in a memory area.

S220, when the (i+1) -th frame display picture is pre-displayed, writing the data signals of the first pixels in the data signals of the (i+1) -th frame display picture into the first pixels in a one-to-one correspondence manner, keeping the data signals of the second pixels as the data signals of the (i) -th frame display picture, controlling the first pixels to display according to the data signals corresponding to the first pixels in the (i+1) -th frame display picture, and controlling the second pixels to display according to the data signals corresponding to the second pixels in the data signals of the (i) -th frame display picture.

The data signals of the i+1th frame display picture comprise data signals corresponding to the first pixels one by one and data signals corresponding to the second pixels one by one, namely, the data signals corresponding to the first pixels one by one in the data signals of the i+1th frame display picture are stored in the memory area, and the data signals corresponding to the second pixels one by one in the data signals of the i+1th frame display picture are stored in the memory area. In this way, when the i+1th frame display screen is pre-displayed, the data signal corresponding to each first pixel in the data signal of the i+1th frame display screen can be extracted from the memory, and the data signal of the i+1th frame display screen corresponding to each second pixel stored in the memory is removed, so that the data signal of the i+1th frame display screen can be written to each first pixel in a one-to-one correspondence manner, and the data signal of the second pixel can be kept as the data signal of the i frame display screen.

S230, acquiring a data signal of the (i+2) th frame display picture, and storing the data signal of the (i+2) th frame display picture in a memory area.

S240, when the (i+2) -th frame display picture is pre-displayed, writing the data signals of the second pixels in the data signals of the (i+2) -th frame display picture into the second pixels in a one-to-one correspondence manner, keeping the data signals of the first pixels as the data signals of the (i+1) -th frame display picture, controlling the second pixels to display according to the data signals corresponding to the second pixels in the data signals of the (i+2) -th frame display picture, and controlling the first pixels to display according to the data signals corresponding to the first pixels in the data signals of the (i+1) -th frame display picture.

The data signals of the i+2 frame display picture comprise data signals corresponding to the first pixels one by one and data signals corresponding to the second pixels one by one, namely, the data signals corresponding to the first pixels one by one in the data signals of the i+2 frame display picture are stored in the memory area, and the data signals corresponding to the second pixels one by one in the data signals of the i+2 frame display picture are stored in the memory area. In this way, when the i+2 frame display screen is pre-displayed, the data signal corresponding to each second pixel in the data signal of the i+2 frame display screen can be extracted from the memory, and the data signal of the i+2 frame display screen corresponding to each first pixel stored in the memory is removed, so that the data signal of the i+2 frame display screen can be written to each second pixel in a one-to-one correspondence manner, and the data signal of the first pixel can be kept as the data signal of the i+1 frame display screen.

Optionally, only the data signals corresponding to the first pixels are written into the first pixels in a one-to-one correspondence manner in the data signals of the i+1st frame display screen, and the data signals of the second pixels are directly truncated; therefore, before the i+1st frame display picture is pre-displayed, only the data signals corresponding to the first pixels in one-to-one mode in the data signals of the i+1st frame display picture are acquired, and the data signals corresponding to the first pixels in one-to-one mode in the data signals of the i+1st frame display picture are stored in the memory area;

correspondingly, only the data signals corresponding to the second pixels are written into the second pixels in a one-to-one correspondence manner in the data signals of the i+2 frame display picture, and the data signals of the first pixels are directly truncated; therefore, only the data signals corresponding to the second pixels one by one in the data signals of the i+2 frame display screen can be obtained before the i+2 frame display screen is pre-displayed, and the data signals corresponding to the second pixels one by one in the data signals of the i+2 frame display screen are stored in the memory area.

Thus, only part of the data signals of each frame of display picture are stored at a time, and the processing amount of the signals can be reduced; meanwhile, the memory area only needs to be provided with partial data signals capable of accommodating each frame of display picture, so that the number of memories arranged in the memory area can be reduced, and the structure of the memory area is facilitated to be simplified; also, since the more memories are provided in the memory area, the higher the cost thereof, when the number of memories provided in the memory area is reduced, the cost can be reduced.
