[0002] Currently, with the development of display technologies for modern display devices, users' requirements for the refresh rate of display systems are continuously increasing.

[0003] In a display control method, a display panel receives row-direction signals at a relatively high frequency to increase the overall refresh rate of the display area of the display device, so as to obtain a more vivid picture display effect and a smoother video display effect, thereby improving the user experience. Among them, the row-direction signals are used to control a scanning drive circuit to drive multiple rows of pixel units in the display panel according to a timing sequence.

[0074] Through the above-mentioned drawings, the specific embodiments of the present application have been shown, and more detailed descriptions will be given later. These drawings and text descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Specific Embodiments

[0075] To make the objectives, technical solutions, and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0076] First, the application scenarios involved in the embodiments of the present application will be introduced.

[0077] The display device includes a display panel and a driving device. The display panel usually includes row direction signal lines (which can also be called scan lines), data lines, and multiple pixels. The driving device includes a data driver and a scan driver. The display panel can display images at a low frequency to reduce power consumption. Exemplarily, when the display panel displays a static image, the refresh rate of the display panel can be relatively low, and when the display panel displays a video, the refresh rate of the display panel can be relatively high.

[0078] The display panel includes multiple pixel units. Usually, when the display panel displays a video, a relatively high refresh rate (also called the driving frequency) is used to make the change of the video picture smoother. The refresh rate can be called the screen refresh rate and represents the frequency of playing the display picture within one second. The refresh rate is the driving frequency of the signal output of the data driver or the scan driver. For example, the refresh rate used to drive the display panel can be 60Hz.

[0079] The implementation environment may include a server and a display panel. The server includes a processor. The server can establish a wired or wireless connection with the display panel to display an image on the display panel.

[0080] Figure 1 It is a flowchart of a display control method provided by an embodiment of the present application. This method can be applied to Figure 1 the display panel in the shown implementation environment. This method includes the following steps:

[0081] Step 101, determine a first display area of the display panel and a second display area located outside the first display area.

[0082] Among them, the display panel includes a plurality of sub - partitions arranged in rows and columns, and a plurality of first switches. The sub - partitions include at least one pixel unit. The first display area includes at least one sub - partition, and the second display area includes at least one sub - partition.

[0083] Step 102: Obtain a row - direction signal and a column - direction signal. The column - direction signal is used to control the connection and disconnection of the first switches in a column of sub - partitions. The pixel units in the first display area correspond to a row - direction signal and a column - direction signal with a first frequency, and at least one of the row - direction signal and the column - direction signal corresponding to the pixel units in the second display area has a second frequency, and the first frequency is different from the second frequency.

[0084] Among them, the first frequency can be greater than the second frequency, or the first frequency can be less than the second frequency.

[0085] Among them, the pixel unit is connected to a row - direction signal line. The first switch is used to control the connection and disconnection of the row - direction signal line, and the row - direction signal line is used to control the connection and disconnection of the driving signal of the pixel unit.

[0086] Step 103: Input the row - direction signal into the row - direction signal line, and control the first switch through the column - direction signal, so that the display panel drives the first display area at the first frequency and drives the second display area at the second frequency.

[0087] In summary, the embodiment of the present application provides a display control method. The display panel receives a control signal, and then drives the first display area at the first frequency and drives the second display area at the second frequency, and the first frequency is different from the second frequency. That is, the refresh rate of the first display area in the display panel is different from the refresh rate of the second display area. The control signal includes a row - direction signal and a column - direction signal. In this way, the display panel can achieve zoned refresh, which can improve the flexibility of the display panel when adjusting the refresh rate, solve the problem that the flexibility of the display panel in adjusting the refresh rate is poor in the related art, and achieve the effect of flexibly adjusting the refresh rate of the display panel.

[0088] In an optional embodiment, Figure 2 is a schematic diagram of zoned refresh of a display panel provided by the embodiment of the present application. Please refer to Figure 2 , the display panel further includes a column - direction signal line for outputting the column - direction signal. The display panel includes 9 sub - partitions, and the 9 sub - partitions are all electrically connected to the row - direction signal line and the column - direction signal line respectively. The 9 sub - partitions are the first sub - partition B1, the second sub - partition B2, the third sub - partition B3, the fourth sub - partition B4, the fifth sub - partition B5, the sixth sub - partition B6, the seventh sub - partition B7, the eighth sub - partition B8, and the ninth sub - partition B9.

[0089] When the row direction signal is 1, it indicates that the output enable signal is output. When the row direction signal is 0, it indicates that no signal is output or the output is disabled. Similarly, when the row direction signal is 1, it indicates that the output enable signal is output. When the row direction signal is 0, it indicates that no signal is output or the output is disabled. When the row direction signal and the column direction signal corresponding to a sub-partition are both 1, the driving signals of the pixel units in the sub-partition are connected, that is, the sub-partition can be driven to be refreshed. When at least one of the row direction signal and the column direction signal corresponding to a sub-partition is 0, the driving signals of the pixel units in the sub-partition are not connected, that is, the sub-partition cannot be driven to be refreshed.

[0090] In Figure 2 the process of double refreshing the display panel shown, in the first refreshing process, only the row direction signal and the column direction signal corresponding to the fifth sub-partition B5 are both 1, and at least one of the row direction signal and the column direction signal corresponding to the other 8 sub-partitions is 0. Therefore, in the first refreshing process, only the fifth sub-partition B5 can be driven to be refreshed.

[0091] In the second refreshing process, the row direction signals and the column direction signals corresponding to the 9 sub-partitions are both 1. Therefore, in the second refreshing process, the 9 sub-partitions can all be driven to be refreshed. Thus, the refresh rate of the fifth sub-partition B5 is higher than that of the other 8 sub-partitions. That is, the fifth sub-partition B5 can be the first display area, and the other 8 sub-partitions can be the second display area. The fifth sub-partition B5 can be driven at the first frequency, and the other 8 sub-partitions can be driven at the second frequency.

[0092] In the related art, when performing partitioned refreshing on a display panel, there are the following two solutions: Solution 1: Perform partitioned refreshing on the display panel based on the row direction signal. Since the display panel is refreshed based on the signal in one direction, it is only possible to perform partitioned refreshing on the display panel in one direction (the row direction), and thus it is impossible to achieve column-wise partitioned refreshing of the display panel. Solution 2: Divide the multiple pixel units in each row into multiple groups of pixel units, and the multiple groups of pixel units are respectively connected to multiple level shift chips to achieve column-wise partitioned refreshing of the display panel. Since the number of rows of the multiple pixel units on the display panel is large, such a setting will result in an excessive number of level shift chips on the display panel, and thus the structure of the display panel is relatively complex. In the embodiments of the present application, the display panel is controlled by the row direction signal and the column direction signal, the first display area is driven at the first frequency, and the second display area is driven at the second frequency. In this way, the display panel can achieve partitioned refreshing in the row direction and the column direction, can flexibly adjust the sizes of the first display area and the second display area, and thus can improve the flexibility of the display panel when adjusting the refresh rate. Moreover, without connecting a large number of level shift chips, the structure of the display panel can be relatively simple.

[0093] Figure 3 It is a flowchart of another display control method provided by an embodiment of the present application. This method can be used for a display panel and may include the following steps:

[0094] Step 201: Obtain the fixation area of the human eye viewing the display panel through the human eye detection component.

[0095] The display panel may include a human eye detection component. Figure 4 It is a schematic diagram showing the determination of the fixation visual field of the human eye shown in an embodiment of the present application. Please refer to Figure 4 , this human eye detection component may include a camera and a face detection unit. The camera can be used to obtain the face image of the person viewing the display panel. The face detection unit can be used to extract the face information on the face image captured by the camera, and then perform human eye information detection. A human eye detection control switch button may be included on the display surface of the display panel, which can be used to turn on or off the human eye detection component.

[0096] It should be noted that when a user views a display panel with a large size, due to the field of view of the human eye, the viewing angle of the display panel, and the screen size, the range of the display panel that the user can see at different distances is different. When the human eye detection component is turned on, the display panel can obtain the distance between the human eye and the display surface of the display panel through the human eye detection component, or obtain the distance and relative position between the human eye and the display surface of the display panel, and at the same time, in combination with the human eye visual characteristics, that is, the comfortable visual field of the human eye, obtain the fixation area of the human eye to obtain the viewing area where the user views the display panel in a relatively comfortable state. In this way, the area on the display panel corresponding to this fixation area can be used as the first display area, and the first display area can be refreshed at a higher frequency so that the video image in the user's fixation area is relatively smooth.

[0097] Optionally, when multiple people view the display panel, the human eye information of multiple people can be obtained through the human eye detection component, and one of the human eye information of multiple people can be selected as the default human eye information. Obtain the display area adjustment information based on the default human eye information. That is, when multiple people view the display panel at the same time, one person can be selected from these multiple people, and the adjustment information of the display area can be obtained according to the human eye information of this one person.

[0098] In an optional implementation manner, obtaining the fixation area of the human eye viewing the display panel may include the following two steps:

[0099] (1) Through the human eye detection component, obtain the distance between the human eye viewing the display panel and the display surface of the display panel and the fixation position of the human eye.

[0100] The display panel can capture a face image of a person viewing the display panel through a camera. The face detection unit obtains the face region in the image based on the face image, and performs facial landmark detection (English: Facial Landmark Detection) within the obtained face region. Facial landmark detection can locate the feature points on the face, such as the corners of the mouth and eyes. Then, the Perspective-n-Point (PnP) algorithm is used to obtain the first distance from the face to the display surface of the display panel. And the first distance from the face to the display surface of the display panel is used as the distance between the human eye and the display surface of the display panel to reduce the computational amount. The above distance can be the vertical distance from the human eye to the display panel.

[0101] The gaze position of the human eye can be obtained by capturing a face image of a person viewing the display device through a camera, then obtaining the position of the pupil and the facial pose of the viewer from the face image, and obtaining the gaze position of the human eye based on the position of the pupil and the facial pose. Exemplarily, as Figure 4 shown, a coordinate system is established with the lower left corner of the display panel as the origin (0, 0). The horizontal axis of this coordinate system is the X-axis, the vertical axis is the Y-axis, the distance from the human eye to the display panel is Z, and the coordinates of the gaze position of the human eye are (X1, Y1).

[0102] (2) Generate a gaze region based on the distance, the gaze position, and a preset human eye visual field.

[0103] The preset human eye visual field can be the gaze range of the human eye at a preset angle. Exemplarily, the preset angle can be the angle of the gaze line of the human eye in one direction. When the preset angle remains unchanged, different distances between the human eye and the display surface can correspond to different sizes of the human eye gaze region.

[0104] The preset angle can include the angle of the gaze line of the human eye in the horizontal direction and the angle of the gaze line of the human eye in the vertical direction.

[0105] Exemplarily, the preset angles in the horizontal and vertical directions are both 3°. Based on the distance between the human eye and the display surface and the preset human eye visual field (preset angle), the size of the gaze visual field of the human eye can be determined.

[0106] As Figure 5 shown, Figure 5 is Figure 4A top-down schematic diagram for determining the fixation field of view of the human eye is shown. If the display area of the display device is rectangular, according to the distance Z and the preset angle, with the human eye as the center, along the perpendicular line from the human eye to the display surface as the reference, the angle α between the line of sight of the human eye and this perpendicular line is half of the preset angle. The abscissa or ordinate of the target point on the edge of the fixation area can be calculated. The shape of this fixation area can be rectangular, and any side of this rectangle is parallel to the long side or the short side of the display area.

[0107] Optionally, the range of the angle α between the line of sight of the human eye and the perpendicular line from the human eye to the display surface can be 2.4° to 4°.

[0108] It should be noted that the preset angles in the horizontal and vertical directions can be other values. For example, the preset angle in the horizontal direction can be 3.5°, and the preset angle in the vertical direction can be 2.5°. The embodiments of the present application do not limit this here.

[0109] Based on the first formula, the abscissa of the target point on the edge of the fixation area is determined. The first formula is X2 = X1 ± Z × tanα, where X2 is the abscissa of the target point on the edge of the fixation area, X1 is the abscissa of the fixation position, Z is the distance, and α is half of the angle of the human eye's field of view.

[0110] As Figure 4 shown, the target points on the edge of the fixation area can include the first point P1, the second point P2, the third point P3, and the fourth point P4. The first point P1, the second point P2, the third point P3, and the fourth point P4 can be the four vertices of the rectangular fixation area. Among them, the abscissas of the first point P1 and the third point P3 can be X2 = X1 - Z × tanα, and the abscissas of the second point P2 and the fourth point P4 can be X2 = X1 + Z × tanα.

[0111] Based on the second formula, the ordinate of the target point on the edge of the fixation area is determined. The second formula is Y2 = Y1 ± Z × tanα, where Y2 is the ordinate of the target point on the edge of the fixation area, and Y1 is the ordinate of the fixation position. Similarly, the ordinates of the first point P1 and the second point P2 can be Y2 = Y1 + Z × tanα, and the ordinates of the third point P3 and the fourth point P4 can be Y2 = Y1 - Z × tanα.

[0112] In this way, the fixation area can be generated based on the abscissas and ordinates of the four target points on the edge of the fixation area.

[0113] Optionally, when multiple people are watching the display device, the eye information of multiple people is obtained through the eye detection component, and one of the eye information of multiple people is selected as the default eye information; and the fixation area is obtained based on the default eye information. The eye information closest to the center of the image among the eye information of multiple people can be determined as the default eye information.

[0114] Step 202: Determine the first display area based on the fixation area.

[0115] The display panel includes a plurality of sub - partitions arranged in rows and columns. By obtaining the coordinates of the fixation area, the sub - partitions located in the fixation area among the plurality of sub - partitions can be determined, and the sub - partitions located in the fixation area are determined as at least one sub - partition in the first display area.

[0116] Step 203: Determine the area other than the first display area in the display panel as the second display area.

[0117] The first display area may include at least one sub - partition. The display panel may further include other sub - partitions outside the at least one sub - partition, and the other sub - partitions may be the second display area. That is, at least one sub - partition located outside the fixation area can be determined as the second display area, and the second display area may be a non - fixation area. In this way, the first display area and the second display area outside the first display area of the display panel can be determined, where the first display area includes at least one sub - partition and the second display area includes at least one sub - partition.

[0118] Optionally, the plurality of sub - partitions may include 6×20 sub - partitions. That is, the display panel can be divided into 20 partitions along the row direction and 6 partitions along the column direction. Exemplarily, the first display area may include 60 sub - partitions and the second display area may include 60 sub - partitions.

[0119] Figure 6 It is a schematic diagram of the partition of another display panel shown in the embodiments of the present application. Please refer to Figure 6 , in an alternative embodiment, the first display area A1 or the second display area A2 on the display panel can also be determined in the following way, or after performing the above steps 201 - 203, the size of the first display area A1 is larger, and there are dynamic images and static images in the first display area A1. In this way, the range of the first display area A1 can be further reduced.

[0120] The method for determining the first display area A1 and the second display area A2 may include, first, detecting the display data of multiple sub - partitions in the display panel. The display data includes dynamic images and static images. The dynamic images may include videos, and the static images may include a menu bar, such as Program 1, Program 2, etc.

[0121] Secondly, in response to detecting that a sub-region includes a moving image, the sub-region is determined as at least one sub-region in the first display area A1 to obtain the first display area A1, which may include a moving image and some static images. Then, the area other than the first display area A1 in the display panel is determined as the second display area A2, and the second display area A2 includes static images.

[0122] Step 204: Obtain a row direction signal and a column direction signal.

[0123] Among them, the column direction signal is used to control the connection and disconnection of the first switches in at least one column of sub-regions.

[0124] The display panel may include a plurality of sub-regions arranged in rows and columns, and a plurality of first switches. The first switches can be used to control the connection and disconnection of the row direction signals of at least one column of sub-regions.

[0125] As Figure 7 shown, Figure 7 is a schematic structural diagram of a display device provided by an embodiment of the present application. The display device may include a control unit and a display panel. The control unit may include a control circuit board and a driving unit (such as Figure 7 SD#1 to SD#8 shown). The control circuit board may include a coordinate processing unit, a control instruction generation unit, a timing processing unit, a driving unit, a data receiving module, a data processing module, and a data sending module. Among them, the coordinate processing unit can be used to receive the distance between the human eye watching the display panel and the display surface of the display panel and the fixation position of the human eye obtained in step 201 above, and determine the first display area and the second display area.

[0126] The control instruction generation unit can generate a row digital signal with a first frequency corresponding to the first display area and a row digital signal with a second frequency corresponding to the second display area based on the determined first display area and second display area, and transmit them to the timing processing unit. The timing processing unit receives the above row digital signals, converts the row digital signals into a row direction signal with a first frequency and a row direction signal with a second frequency, and transmits the row direction signal with a first frequency and the row direction signal with a second frequency to the first display area and the second display area respectively. The control instruction generation unit can also generate a column digital signal with a first frequency corresponding to the first display area and a column digital signal with a second frequency corresponding to the second display area based on the determined first display area and second display area, and transmit them to the driving unit. The driving unit receives the above column digital signals, converts the column digital signals into a column direction signal with a first frequency and a column direction signal with a second frequency, and transmits the column direction signal with a first frequency and the column direction signal with a second frequency to the first display area and the second display area respectively.

[0127] A data receiving module is used to determine a first display area and a second display area according to a coordinate processing unit, and transmit a data / timing synchronization signal to a timing processing unit. A data processing module is electrically connected to the data receiving module and is used to process signals of the first display area and the second display area received by the data receiving module. The data processing module rearranges image data according to the display information of the first display area and the second display area, and at the same time transmits the data / timing synchronization signal to the timing processing unit, so that the timing processing unit outputs a row direction signal and a column direction signal at a transmission rate synchronized with the image data, to ensure the accuracy of reading data when the display panel displays an image. And the driving signals corresponding to the image data are respectively transmitted to the first display area and the second display area through a data sending module.

[0128] Specifically, the data processing module rearranges the image data, including: First, obtain the image data, which is used to control the display panel to display an image screen. Second, process the image data into a first driving signal corresponding to the first display area and a second driving signal corresponding to the second display area, to rearrange the image data. After that, transmit the first driving signal to the first display area at a first frequency, and output the second driving signal to the second display area at a second frequency. That is to say, a row direction signal and a column direction signal, as well as a first driving signal and a second driving signal can be synchronously generated, and the display panel is driven based on the above signals. Exemplarily, within a unit time, the data processing module sends the first driving signal to the data sending module twice, and sends the second driving signal to the data sending module once.

[0129] Step 205: Control the display panel based on the row direction signal and the column direction signal, so that the display panel drives the first display area at a first frequency and drives the second display area at a second frequency.

[0130] Among them, the first frequency can be greater than the second frequency.

[0131] In this way, the two display areas (the first display area and the second display area) on the display panel can drive the first display area at a first frequency and drive the second display area at a second frequency according to the control signals (the column direction signal and the row direction signal) output in two directions. That is to say, the display panel can receive the control signal, and then drive the first display area at a first frequency and drive the second display area at a second frequency, and the first frequency is greater than the second frequency. The control signal includes a row direction signal and a column direction signal. In this way, the display panel can achieve zoned refreshing, can reduce the power consumption of the display panel, solves the problem that the too high refresh rate of the entire screen in the related art causes a large power consumption of the display panel, and achieves the effect of reducing the power consumption of the display panel.

[0132] Specifically, different refresh frequencies are presented in the human eye fixation area and the non-human eye fixation area, enabling the pixels in the area of the display panel that do not need to be refreshed to be held. The pixels to be held do not require the data line to recharge the pixel electrode again, which can reduce the power consumption of the display panel. Moreover, the pixels to be held are not interfered by the signals generated by other refreshed pixels. While effectively reducing the power consumption of the display panel, the display effect of the display panel is improved.

[0133] The first display area may include the human eye fixation area. By refreshing the human eye fixation area at a high frequency and refreshing the non-human eye fixation area at a low frequency, the display power consumption can be reduced.

[0134] In an alternative embodiment, as Figure 8 and Figure 9 shown, Figure 8 is a schematic structural diagram of a driving circuit in a display panel provided by an embodiment of the present application. Figure 9 is Figure 8 a schematic structural diagram of a pixel driving circuit in the driving circuit shown.

[0135] The display panel may further include a row direction signal line (gate), a column direction signal line (GC, Gate control), a second switch 302, and a data line (data). Both the first switch 301 and the second switch 302 include a control terminal, a first terminal, and a second terminal. The first terminal and the second terminal are turned on or off under the control of the control terminal. The control terminal of the first switch 301 is electrically connected to the column direction signal line (GC). The first terminal and the second terminal of the first switch 301 are respectively electrically connected to the row direction signal line (gate) and the control terminal of the second switch 302. The first terminal and the second terminal of the second switch 302 are respectively electrically connected to the data line (data).

[0136] The column direction signal can be transmitted to the first switch 301 through the column direction signal line (GC), and the column direction signal can be used to control the connection and disconnection of multiple first switches 301 in a column of sub-partitions. The first terminals of multiple first switches 301 in a column of sub-partitions can be respectively electrically connected to multiple row direction signal lines (gate), and multiple row direction signals can be respectively transmitted to the first terminals of multiple first switches 301 through the row direction signal line (gata).

[0137] Exemplarily, when the column direction signal is high, the first switch 301 can be turned on to transmit the row direction signal to the control terminal of the second switching transistor 302, so that the second switch 302 is turned on, and then the driving signal is transmitted to the pixel (Cpixel) of the display panel to make the pixel emit light. In this way, the pixels in at least one sub-region on the display panel can generate a row direction signal and a column direction signal according to the timing. Under the combined control (turning on or off) of the two, the pixels in each sub-region on the display panel are controlled to display an image.

[0138] Exemplarily, as Figure 10 shown, Figure 10 is a schematic structural diagram of a driving unit of a display panel provided by an embodiment of the present application. The driving unit includes a timing control module, a voltage conversion module, and a power control module. The timing control module is used to receive a column digital signal and output a timing control instruction. The power control module is used to output a reference voltage. The voltage conversion module receives the timing control instruction and converts the timing control instruction into a column direction signal (voltage control signal) according to the reference voltage. The column direction signal is used to drive the first switch in the first display area at a first frequency and drive the first switch in the second display area at a second frequency. The voltage range of the column direction signal is 0V to 18V.

[0139] Specifically, the control instruction generation unit outputs 20-bit column digital signals based on the SPI protocol. The 20-bit column digital signals correspond to the driving (on / off) conditions of different sub-regions. For example, 0001 0000 0000 0000 0000 0 means that during the refresh process of the display panel this time, the 4th sub-region in the column direction is on and can refresh the screen, and other sub-regions are off and do not perform screen refresh. The timing control module receives the 20-bit column digital signal and generates 20 timing control instructions (the 20 timing control instructions can include at least a pair of analog signals with opposite phases). And, the voltage conversion module can perform level conversion on the timing control instruction based on the reference voltage output by the power control module (the range of the level conversion is 0V to 18V. Exemplarily, a 1.8V timing control instruction can be converted into an 18V voltage control signal), that is, convert the timing control instruction (analog signal) generated by the timing control module into a column direction signal (the column direction control signal can be a voltage control signal, with a range of 0V to 18V) to control the first switch.

[0140] As Figure 11 shown, Figure 11 is a schematic waveform diagram of a column direction signal provided by an embodiment of the present application. The column direction control signal output by the driving unit can include at least a pair of analog signals output with opposite phases, so that the driving unit can be applicable to pixel driving circuits with different structures.

[0141] In this way, the display panel can control the display panel based on the row direction signal and the column direction signal, so that the display panel drives the first display area at a first frequency and drives the second display area at a second frequency.

[0142] Specifically, in the first display area, the column direction signal line transmits the column direction signal to the first switch at the first frequency, so that the row direction signal sequentially passes through the row direction signal line and the first switch and is transmitted to the second switch, and then the driving signal is transmitted to the pixel of the display panel to make the pixel emit light.

[0143] In the second display area, the column direction signal line transmits the column direction signal to the first switch at the second frequency, so that the row direction signal sequentially passes through the row direction signal line and the first switch and is transmitted to the second switch, and then the driving signal is transmitted to the pixel of the display panel to make the pixel emit light.

[0144] The first frequency and the second frequency can be set according to actual needs. For example, when the first frequency is 120 Hz, the second frequency can be 60 Hz; when the first frequency is 60 Hz, the first frequency can be 30 Hz, etc. When the first frequency is as high as possible, the refresh rate of the fixation area can be made as high as possible, so that the display image in the fixation area is quickly refreshed, reducing the delay phenomenon of the image in the human eye fixation area; while when the second frequency is as low as possible, the power consumption of the display panel can be reduced, thus avoiding the problem of device heating caused by high power consumption and improving the user experience.

[0145] Optionally, the refresh rate of the first display area is N times that of the second display area, where N is an integer greater than or equal to 1.

[0146] The first display area and the second display area can be driven by one driving unit respectively; for another example, the first display area and the second display area can also be driven by the same driving unit.

[0147] Step 206: Determine the third display area of the display panel. The third display area is located between the first display area and the second display area.

[0148] Control the display panel based on the row direction signal and the column direction signal, so that the display panel drives the third display area at a third frequency. The third refresh rate is less than the first frequency and greater than the second frequency.

[0149] By setting the third display area with a refresh rate between the first frequency of the first display area and the second frequency of the second display area between the first display area and the second display area, not only can the display quality be improved while alleviating the problem of increased power consumption caused by the increase in the refresh rate, but also the problem of discomfort to the human eye that may be caused by the sudden change of the refresh rate in space can be avoided.

[0150] In summary, the embodiment of the present application provides a display control method. The display panel receives a control signal, and then drives the first display area at a first frequency and the second display area at a second frequency, and the first frequency is different from the second frequency, that is, the refresh rate of the first display area in the display panel is different from that of the second display area. The control signal includes a row direction signal and a column direction signal. In this way, the display panel can achieve zoned refreshing, which can improve the flexibility of the display panel when adjusting the refresh rate, solves the problem of poor flexibility of the display panel when adjusting the refresh rate in the related art, and achieves the effect of flexibly adjusting the refresh rate of the display panel.
