[0043] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0044] Currently, there is only one refresh rate for a display panel, that is, the refresh rates of different display partitions of the same display panel are the same. However, different display partitions of the same display panel do not necessarily all need to refresh data under the same display frame. If different display partitions of the same display panel use the same refresh rate to refresh data, it will cause the power consumption of the display panel to increase. Although a High Definition Render Pipeline (HDPR) scheme is proposed to reduce the power consumption of the display screen, the driving timing of a conventional voltage shift register (VSR) cannot meet the display requirements of the dynamic partition of the display panel. The HDPR scheme proposes a dynamic partition refresh display technology of the display panel, which can divide the display panel into a plurality of partitions, and the refresh rate of each partition can be independently set. Through the scheme, the effect of reducing the driving power consumption of the display panel can be achieved.

[0045] The dynamic partition refresh display function of the display panel requires special driving timing. Therefore, the embodiment of the present application provides a driving method of a display panel. The driving timing corresponding to the display panel is determined through the display frame state of a plurality of display partitions, the refresh frequency of each display partition can be independently set, the functional requirements of the dynamic partition display refresh of the display panel are met, and the driving power consumption of the display panel is reduced.

[0046] Please refer to Figure 1 , a flowchart of a driving method of a display panel provided by the embodiment of the present application is shown, and the embodiment of the present application at least includes the following steps:

[0047] S1, a plurality of groups of driving timing stored in advance are obtained. Under the action of different driving timing, a plurality of display partitions display the to-be-displayed data corresponding to the display partitions at different refresh frequencies.

[0048] In the embodiment of the present application, the display panel includes a display area and a non-display area, and the display area includes a plurality of display partitions. As shown in Figure 2 , the display area of the display panel can include two display partitions, or three display partitions, or more display partitions. For example, the three display partitions can include a first display partition, a second display partition and a third display partition. Further, the display area is sequentially the first display partition, the second display partition and the third display partition from top to bottom. The number of display partitions can be set according to actual conditions, and the embodiment of the present application does not limit it.

[0049] If the display panel needs to be partitioned and refreshed, a plurality of groups of driving timing stored in advance can be obtained. Under the action of driving timing in different groups, a plurality of display partitions can display the to-be-displayed data corresponding to the display partitions at different refresh frequencies. For example, the driving timing is the first driving timing, the first driving timing corresponds to the first group of refresh frequencies, and the plurality of display partitions are refreshed at the first group of refresh frequencies. The first group of refresh frequencies can include refresh frequencies corresponding to the plurality of display partitions respectively, which can be the same or different.

[0050] In some embodiments of the present application, each group of driving timing in the plurality of groups of driving timing of the embodiments of the present application includes driving timing of a P-type scanning circuit and driving timing of an N-type scanning circuit. The P-type scanning circuit is used to control the scanning of the scanning circuit SCAN, and the N-type scanning circuit is used to control the light emission of the organic light-emitting layer EM.

[0051] S2, determine the display frame state corresponding to each of the plurality of display partitions.

[0052] The display frame state corresponding to each of the plurality of display partitions is determined, i.e., whether there is data refresh for each of the plurality of display partitions. The display frame state includes an effective frame and a blank frame. The effective frame indicates that there is data refresh in the current frame, and the blank frame indicates that there is no data refresh in the current frame, i.e., the display data of the previous display frame is maintained for display. Taking a display panel including three display partitions as an example, if the display frame states of the first display partition, the second display partition and the third display partition are all effective frames, it indicates that the three display partitions all need to be refreshed. If the display frame states of the first display partition and the third display partition are blank frames, and the display frame state of the second display partition is an effective frame, it indicates that only the second display partition needs to be refreshed among the three display partitions.

[0053] Therefore, one of the implementation manners of determining the display frame state corresponding to each of the plurality of display partitions in the embodiments of the present application can include:

[0054] If the display partition has to-be-displayed data, the display frame state of the display partition is determined as an effective frame;

[0055] If the display partition has no to-be-displayed data, the display frame state of the display partition is determined as a blank frame.

[0056] The display frame state is determined in the embodiments of the present application, which prepares for the subsequent determination of the to-be-driven timing. If the display frame state is determined as a blank frame, the refresh frequency of the display partition with the blank frame can be reduced, so as to meet the functional requirements of the dynamic partition display refresh of the display panel and reduce the driving power consumption of the display panel.

[0057] S3, find the to-be-driven timing corresponding to the display frame state in the plurality of groups of driving timing.

[0058] S4, driving the display panel based on the to-be-driven timing.

[0059] In the embodiment of the present application, a plurality of groups of driving timing are stored in advance. When the display panel needs to switch the refresh frequency, only the to-be-driven timing corresponding to the refresh frequency to be switched needs to be found in the plurality of groups of driving timing, so that the display panel can be driven by the to-be-driven timing, and the display panel can be refreshed at the required refresh frequency.

[0060] Since the display panel in the embodiment of the present application includes a plurality of display partitions, a to-be-driven timing corresponding to the display frame state of each of the plurality of display partitions needs to be found in the plurality of groups of driving timing. If the plurality of display partitions of the display panel includes a first display partition, a second display partition and a third display partition, a to-be-driven timing corresponding to the display frame state of the first display partition, the display frame state of the second display partition and the display frame state of the third display partition needs to be found in the plurality of groups of driving timing.

[0061] The display frame state of the first display partition, the display frame state of the second display partition and the display frame state of the third display partition corresponding to each group of driving timing in the plurality of groups of driving timing are different. For example, the driving timing is the second driving timing, the display frame state of the first display partition corresponding to the second driving timing is the active frame, the display frame state of the second display partition is the active frame, and the display frame state of the third display partition is the active frame. The driving timing is the third driving timing, the display frame state of the first display partition corresponding to the third driving timing is the blank frame, the display frame state of the second display partition is the active frame, and the display frame state of the third display partition is the blank frame.

[0062] In the embodiment of the present application, the non-display area of the display panel includes a P-type scan circuit SCAN P and an N-type scan circuit SCAN N.

[0063] In the plurality of display frames, the driving timing of the P-type scan circuit of the plurality of display frames is consistent regardless of whether the display frame state of the plurality of display partitions of each display frame is consistent. Assuming that the plurality of display partitions of the display panel includes a first display partition, a second display partition and a third display partition, there are a first display frame and a second display frame. In the first display frame, the display frame state of the first display partition, the second display partition and the third display partition is the active frame; in the second display frame, the display frame state of the first display partition and the third display partition is the blank frame, and the display frame state of the second display partition is the active frame. The driving timing of the P-type scan circuit of the first display frame is the same as the driving timing of the P-type scan circuit of the second display frame.

[0064] When the display frame state of the display partition is a blank frame, the N-type scan circuit of the display partition is maintained in a low voltage state (i.e. Holding VGL), that is, the N-type scan circuit does not work; when the display frame state of the display partition is a valid frame, the N-type scan circuit of the display partition is in a working voltage state, that is, the N-type scan circuit normally works. Assuming that the plurality of display partitions of the display panel include a first display partition, a second display partition and a third display partition, if the display frame states of the first display partition and the third display partition are blank frames, the driving timing of the N-type scan circuit corresponding to the first display partition in the to-be-driven timing is maintained in a low voltage state, the driving timing of the N-type scan circuit corresponding to the second display partition in the to-be-driven timing is in a working voltage state, and the driving timing of the N-type scan circuit corresponding to the third display partition in the to-be-driven timing is also maintained in a low voltage state.

[0065] As shown in FIG. 1, Figure 3 a driving timing diagram of a group of display partitions whose display frame states are all valid frames is provided, Figure 3 which represents the driving timing under high frequency of the display panel, at this time, the display frame states of the first display partition, the second display partition and the third display partition are all valid frames, and SCAN P and SCAN N normally work, at this time, the data DATA refresh occurs in the first display partition, the second display partition and the third display partition, that is, the voltage on the integrated circuit data line of the first display partition, the second display partition and the third display partition is all the DATA voltage.

[0066] As shown in FIG. 2, Figure 4 a driving timing diagram of a group of display partitions whose display frame states are all blank frames is provided, Figure 4 which represents the driving timing of the display partition variable frequency display, at this time, the display frame states of the first display partition and the third display partition are changed to blank frames, which is represented as SCAN P normally working and SCAN N being maintained at VGL on the driving, that is, SCAN N does not work; the display frame state of the second display partition is maintained as a valid frame, which is represented as SCAN P normally working and SCAN N normally working on the driving, at this time, the voltage on the integrated circuit data line of the valid frame is the DATA voltage, and the voltage on the integrated circuit data line of the blank frame is the Vpark voltage, that is, only the second display partition refreshes DATA.

[0067] the driving timing of a group of display partitions whose display frame states are all valid frames is provided, Figure 5 at this time, the DATA refresh occurs in the first display partition and the second display partition, and the third display partition is in a Vpark voltage state.

[0068] The driving timing of the display frame state of the first display partition being a blank frame and the display frame state of the second display partition and the third display partition being valid frames is as shown in FIG. 8, at which time the DATA refresh occurs in the second display partition and the third display partition, and the first display partition is in a Vpark voltage state. Figure 6

[0069] The embodiment of the present application can meet the driving requirement of dynamic partition display refresh by setting the driving mode of the N-type scanning circuit of different display partitions.

[0070] In an implementation manner, the process of obtaining the plurality of groups of driving timing stored in advance can include: obtaining the plurality of groups of driving timing stored in advance from a driving chip, or obtaining the plurality of groups of driving timing stored in advance from a memory (Flash) of a printed circuit board.

[0071] When the driving timing is obtained from the driving chip, the plurality of groups of driving timing are integrated in the driving chip in advance, for example, the plurality of groups of driving timing are integrated in a micro control unit (MCU) of the driving chip. When the driving timing is obtained from the printed circuit board, the plurality of groups of driving timing are integrated in firmware (FW) in advance and burned into the memory of the printed circuit board.

[0072] It should be noted that when the plurality of groups of driving timing are integrated in the printed circuit board, the driving timing does not need to occupy the storage space in the MCU of the driving chip, thereby avoiding the problem of rising chip cost caused by the increase in the size of the driving chip and reducing the cost of the display panel.

[0073] In the embodiment of the present application, the plurality of groups of driving timing stored in advance are obtained; the display frame state of the plurality of display partitions is determined; the to-be-driven timing corresponding to the display frame state is searched in the plurality of groups of driving timing; and the display panel is driven based on the to-be-driven timing. The corresponding driving timing is determined by the display frame state of the plurality of display partitions, the refresh rate of each display partition can be independently set, the functional requirement of dynamic partition display refresh of the display panel is met, and the driving power consumption of the display panel is reduced.
