The display panel comprises a plurality of gate drivers and a plurality of pixel units. The plurality of pixel units are located in the display area. The display area comprises a plurality of sub-areas which are not overlapped with one another. The plurality of gate drivers are in one-to-one correspondence with the plurality of sub-regions, and each gate driver is used for scanning the pixel units in the corresponding sub-region line by line, so that the corresponding sub-region displays an image.

Description

Display panels and electronic devices

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on November 24, 2022, with application number 202211480603.7 and application name “Display Panel and Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of display technology, and in particular to a display panel and an electronic device. Background Art

[0003] When electronic devices such as mobile phones, tablets, and laptops are in operation, their display panels can display images at a certain refresh rate. The refresh rate refers to the number of frames per second that the display panel displays.

[0004] In related technologies, electronic devices can adjust the refresh rate of their display panels based on different application scenarios. For example, when the display panel is used to display static images such as pictures or text, the refresh rate can be adjusted to a lower first refresh rate; when the display panel is used to display dynamic images such as videos, the refresh rate can be adjusted to a higher second refresh rate. The higher the refresh rate, the greater the power consumption of the display panel.

[0005] However, when an electronic device is operating, a portion of the display panel may display dynamic images while another portion displays static images. In this case, if the refresh rate of the display panel is adjusted to the first refresh rate, the dynamic image display effect cannot be guaranteed; if the refresh rate of the display panel is adjusted to the second refresh rate, the area of ​​the display panel used to display static images will consume more power.

[0006] Summary of the Invention

[0007] The present application provides a display panel and electronic device. When a portion of the display panel displays dynamic images and another portion displays static images, the display panel can ensure the display effect of the dynamic images while reducing the power consumption of the area used to display the static images. The technical solution is as follows:

[0008] In a first aspect, a display panel is provided. The display panel includes multiple gate drivers and multiple pixel units. The "multiple" here refers to two or more integers. The display panel has a display area. The multiple pixel units are arranged in a matrix of M rows and N columns within the display area. Both M and N are positive integers. When the display panel is in operation, the multiple pixel units emit light to display an image. In the present application, the display area of ​​the display panel includes multiple non-overlapping sub-areas. At least two of the multiple sub-areas are arranged along the column direction.

[0009] The number of gate drivers is equal to the number of sub-regions, and the multiple gate drivers correspond to the multiple sub-regions one-to-one. Each gate driver in the multiple gate drivers is connected to each pixel unit in the corresponding sub-region. When the display panel is working, each gate driver is used to scan the pixel units in the corresponding sub-region row by row. The pixel units emit light after being scanned by the gate driver. In this way, after the gate driver scans all the pixel units in the corresponding sub-region once, the corresponding sub-region can display one frame of image. In the present application, when the display panel is working, the refresh frequencies of different sub-regions in the multiple sub-regions are different. The refresh frequency of a sub-region refers to the number of times any pixel unit in the sub-region is scanned by the gate driver per second. That is to say, different sub-regions display different numbers of frames of images per second under the scanning of the corresponding gate driver.

[0010] In the present application, the display panel includes a plurality of gate drivers and a plurality of pixel units. The plurality of pixel units are located in the display area. The display area includes a plurality of sub-areas that do not overlap with each other. The plurality of gate drivers correspond one-to-one to the plurality of sub-areas, and each gate driver is used to scan the pixel units in the corresponding sub-area row by row, so that the corresponding sub-area displays an image. When the display panel is working, the refresh frequencies of different sub-areas are different. In this way, when the display panel is used to display dynamic images and static images at the same time, the sub-area used to display dynamic images can have a higher refresh frequency, and the sub-area used to display static images can have a lower refresh frequency, thereby ensuring the display effect of the dynamic image and reducing the power consumption generated by the sub-area used to display the static image.

[0011] In some embodiments, the plurality of sub-regions include a first sub-region and a second sub-region, and the first sub-region and the second sub-region are arranged along a column direction.

[0012] In some other embodiments, the plurality of sub-regions include a first sub-region, a second sub-region, and a third sub-region, wherein the first sub-region and the second sub-region are arranged in a column direction, the first sub-region and the third sub-region are arranged in a row direction, and the second sub-region and the third sub-region are arranged in a row direction.

[0013] In some further embodiments, the plurality of sub-regions include a first sub-region, a second sub-region, a third sub-region, and a fourth sub-region, wherein the first sub-region and the second sub-region are arranged in a column direction, the third sub-region and the fourth sub-region are arranged in a column direction, the first sub-region and the third sub-region are arranged in a row direction, and the second sub-region and the fourth sub-region are arranged in a row direction.

[0014] In some embodiments, when the plurality of subregions include a first subregion and a second subregion arranged along a column direction, the number of rows of pixel units in the first subregion may be less than or equal to the number of rows of pixel units in the second subregion.

[0015] In some embodiments, when the display panel is operating, each gate driver is used to scan the pixel units in the corresponding sub-area row by row at a target refresh frequency. The target refresh frequency here can be any one of a plurality of preset refresh frequencies. The plurality of preset refresh frequencies can include at least two of 30 Hz, 60 Hz, 90 Hz, and 120 Hz. For example, if the plurality of preset refresh frequencies include 30 Hz, 60 Hz, and 90 Hz, then when the display panel is used to display dynamic images and static images at the same time, the target refresh frequency of the sub-area used to display dynamic images can be 90 Hz, and the target refresh frequency of the sub-area used to display static images can be 30 Hz or 60 Hz.

[0016] In some embodiments, the display panel further includes a plurality of scan signal lines. A row of pixel units in each of the plurality of sub-regions is connected to a corresponding gate driver via one of the plurality of scan signal lines, and one of the plurality of scan signal lines is connected to only one row of pixel units in one of the plurality of sub-regions. In this way, when the display panel is operating, each gate driver can output a scan signal to any scan signal line, thereby scanning a row of pixel units in the corresponding sub-region connected to that scan signal line.

[0017] In some embodiments, the display panel further includes a data driver and a plurality of data signal lines. A column of pixel units in each of the plurality of sub-regions is connected to the data driver via one of the plurality of data signal lines, and one of the plurality of data signal lines is connected to a column of pixel units in one of the plurality of sub-regions. In this way, when the display panel is operating, the data driver can output a data signal to any of the data signal lines. When a scan signal is input into a scan signal line and a data signal line is input into a data signal line, a data signal can be written to the pixel unit connected to this scan signal line and this data signal line, and at this time, the pixel unit operates and emits light.

[0018] In some embodiments, the display panel may include two data drivers and a plurality of data signal lines. The two data drivers may be a first data driver and a second data driver.

[0019] In a first possible implementation, the multiple sub-regions include a first sub-region and a second sub-region. In this case, a column of pixel units in the first sub-region may be connected to a first data driver via one data signal line from among the multiple data signal lines. A column of pixel units in the second sub-region may be connected to a second data driver via one data signal line from among the multiple data signal lines. One data signal line from among the multiple data signal lines may be connected only to a column of pixel units in one of the multiple sub-regions.

[0020] In a second possible implementation, the multiple sub-regions include a first sub-region, a second sub-region, and a third sub-region. In this case, a column of pixel units in the first sub-region may be connected to the first data driver via one data signal line from the multiple data signal lines. A column of pixel units in the second and third sub-regions may be connected to the second data driver via one data signal line from the multiple data signal lines. One data signal line from the multiple data signal lines may be connected only to a column of pixel units in one of the multiple sub-regions.

[0021] In a third possible implementation, the multiple sub-regions include a first sub-region, a second sub-region, a third sub-region, and a fourth sub-region. In this case, a column of pixel units in the first sub-region and the third sub-region may be connected to the first data driver via one data signal line from the multiple data signal lines. A column of pixel units in the second sub-region and the fourth sub-region may be connected to the second data driver via one data signal line from the multiple data signal lines. One data signal line from the multiple data signal lines may be connected only to a column of pixel units in one sub-region of the multiple sub-regions.

[0022] In the three possible implementations described above, the display panel includes a first data driver and a second data driver. In this case, the sub-region near the first data driver can be driven by the data signal output by the first data driver; the sub-region near the second data driver can be driven by the data signal output by the second data driver. This shortens the length of the data signal line, thereby reducing the loss caused by the data signal line and improving the display brightness of the display panel.

[0023] In a second aspect, an electronic device is provided, comprising a display panel as described in any one of the first aspects.

[0024] The technical effect obtained by the above-mentioned second aspect is similar to the technical effect obtained by the corresponding technical means in the above-mentioned first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0056] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0057] It should be understood that the “multiple” mentioned in this application refers to two or more. In the description of this application, unless otherwise specified, “ / ” means or, for example, A / B can mean A or B; “and / or” in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of this application, words such as “first” and “second” are used to distinguish between identical or similar items with basically the same functions and effects. Those skilled in the art can understand that words such as “first” and “second” do not limit the quantity and execution order, and words such as “first” and “second” do not necessarily limit them to be different.

[0058] Before explaining the display panel provided in the embodiment of the present application in detail, the application scenarios of the display panel are first explained.

[0059] Electronic devices include smart screens (i.e., TVs), mobile phones, tablet computers, and laptop computers. Taking a mobile phone as an example, FIG1 is a schematic diagram of the appearance of an electronic device 01 in the related art. As shown in FIG1 , the electronic device 01 has a display panel 10 for displaying images.

[0060] FIG2 is a schematic diagram of a display area 110 of a display panel 10 in the related art, and FIG3 is a schematic diagram of the structure of the display panel 10 in the related art. As shown in FIG2 and FIG3, the display panel 10 has a display area 110. The display panel 10 includes a gate driver 120, a data driver 130, and a plurality of pixel units 1102. The plurality of pixel units 1102 are located within the display area 110 of the display panel 10 and are arranged in an array. Generally, the pixel units 1102 located in the same row are connected to the gate driver 120 via a scan signal line (the scan signal lines shown in the figure include G1, G2, G3, G4, and G5), and the pixel units 1102 located in the same column are connected to the data driver 130 via a data signal line (the data signal lines shown in the figure include S1, S2, S3, S4, S5, S6, S7, S8, S9, and S10). When the display panel 10 is operating, the gate driver 120 sequentially outputs scan signals to G1, G2, G3, G4, and G5, thereby scanning a plurality of pixel units 1102 row by row. When the gate driver 120 outputs scan signals, the data driver 130 is used to output data signals to S1, S2, S3, S4, S5, S6, S7, S8, S9, and S10. In this way, when a scan signal line inputs a scan signal and a data signal line inputs a data signal, the pixel unit 1102 connected to this scan signal line and this data signal line can operate and emit light. After the gate driver 120 scans all pixel units 1102 of the display panel 10 row by row once, the display panel 10 displays a frame of image.

[0061] When the electronic device 01 is working, the display panel 10 of the electronic device 01 can display images at a certain refresh frequency. The refresh frequency refers to the number of frames of the image displayed by the display panel 10 per second. In the related art, the electronic device 01 can adjust the refresh frequency of the display panel 10 according to different application scenarios. For example, when the display panel 10 is used to display static images such as pictures or text, the refresh frequency of the display panel 10 can be adjusted to a lower first refresh frequency. The first refresh frequency is, for example, 60 Hz (Hertz). When the display panel 10 is used to display dynamic images such as videos, the refresh frequency of the display panel 10 can be adjusted to a higher second refresh frequency. The second refresh frequency is, for example, 120 Hz. The higher the refresh frequency, the greater the power consumption of the display panel 10.

[0062] However, when the electronic device 01 is working, there may be a situation where a part of the display area 110 of the display panel 10 displays a dynamic picture and another part of the display area displays a static picture. For example, Figure 4 is a schematic diagram of an application scenario of the display panel 10 in the related art. As shown in Figure 4, the upper half of the display area 110 is used to display the live video of "User 1", and the lower half of the display area 110 is used to display static pictures such as chat content and input boxes of other users (including "User 01", "User 02" and "User 03"). In this case, if the refresh frequency of the display panel 10 is adjusted to the first refresh frequency, the display effect of the dynamic picture cannot be guaranteed; if the refresh frequency of the display panel 10 is adjusted to the second refresh frequency, then the area of ​​the display panel 10 used to display the static picture will generate greater power consumption.

[0063] To this end, an embodiment of the present application provides a display panel and an electronic device. When the display panel displays dynamic images in one area and static images in another area, it can not only ensure the display effect of the dynamic images but also reduce the power consumption generated by the area used to display static images.

[0064] The display panel provided in the embodiments of the present application is explained in detail below. The display panel provided in the embodiments of the present application can be applied to electronic devices. In the embodiments of the present application, the electrical connection between two electronic devices refers to the connection between the two electronic devices via a wire for the transmission of electrical signals. In the various figures of the present application, the arrowed curves all point to sub-areas of the display area of ​​the display panel, and different sub-areas are divided by dotted lines.

[0065] FIG5 is a schematic diagram of the structure of a display panel 20 provided in an embodiment of the present application. As shown in FIG5 , the display panel 20 includes a gate driver 220 and a plurality of pixel units 2102. The term "plurality" here refers to two or more integers.

[0066] Specifically, the gate driver 220 may be a shift register circuit formed by connecting multiple shift register units. The gate driver 220 may have an input terminal and multiple output terminals. The input terminal of the gate driver 220 is used to input a timing signal. When the gate driver 220 operates, it is affected by the timing signal input from the input terminal, and the multiple output terminals can sequentially output scan signals.

[0067] The display panel 20 has a display area 210. The display area 210 refers to the area used to display images when the display panel 20 is working. Multiple pixel units 2102 are all located in the display area 210. The image displayed when the display panel 20 is working is formed by the luminous pixel units 2102. Multiple pixel units 2102 can be arranged in a matrix of M rows and N columns in the display area 210. Here, M and N are both positive integers. In some specific embodiments, when the resolution of the display panel 20 is 1920×1080, M can be 1920 and N can be 3240 (i.e., 1080×3). In the embodiment shown in Figure 5, a first direction X and a second direction Y that are perpendicular to each other are shown. The first direction X is the horizontal direction along the paper, that is, the direction of the "row" in the embodiment of the present application (i.e., the row direction). The second direction Y is the vertical direction along the paper, that is, the direction of the "column" in the embodiment of the present application (i.e., the column direction).

[0068] In an embodiment of the present application, the display area 210 of the display panel 20 may include multiple sub-areas. The multiple sub-areas do not overlap with each other. The display panel 20 also includes multiple gate drivers 220. The number of gate drivers 220 can be equal to the number of sub-areas, so that the multiple gate drivers 220 correspond to the multiple sub-areas one-to-one. Each gate driver 220 in the multiple gate drivers 220 is connected to each pixel unit 2102 in the corresponding sub-area. When the display panel 20 is in operation, each gate driver 220 is used to scan the pixel units 2102 in the corresponding sub-area row by row. For example, in the embodiment shown in Figure 5, the multiple gate drivers 220 include a first gate driver 222 and a second gate driver 224, and the display area 210 includes a first sub-area 212 and a second sub-area 214. The first gate driver 222 corresponds to the first sub-area 212, and the second gate driver 224 corresponds to the second sub-area 214. In other words, the first gate driver 222 is connected to each pixel unit 2102 in the first sub-area 212. When the first gate driver 222 is in operation, it can scan the pixel units 2102 in the first sub-region 212 row by row. The second gate driver 224 is connected to each pixel unit 2102 in the second sub-region 214. When the second gate driver 224 is in operation, it can scan the pixel units 2102 in the second sub-region 214 row by row.

[0069] After the gate driver 220 scans all pixel units 2102 in the corresponding sub-region once, the corresponding sub-region can display one frame of image. Still taking the display panel 20 shown in FIG5 as an example, that is, after the first gate driver 222 scans all pixel units 2102 in the first sub-region 212 row by row once, the first sub-region 212 can display one frame of image. After the second gate driver 224 scans all pixel units 2102 in the second sub-region 214 row by row once, the second sub-region 214 can display one frame of image.

[0070] In an embodiment of the present application, when the display panel 20 is operating, different sub-regions have different refresh frequencies. The refresh frequency of a sub-region refers to the number of times per second that any pixel unit 2102 in the sub-region is scanned by the gate driver 220. In other words, different sub-regions display different frames of images per second under the scanning of the corresponding gate driver 220. Taking the display panel 20 shown in Figure 5 as an example, the time it takes for all pixel units 2102 in the first sub-region 212 to be scanned row by row by the first gate driver 222 may not be equal to the time it takes for all pixel units 2102 in the second sub-region 214 to be scanned row by row by the second gate driver 224. In this case, the number of frames of images displayed per second in the first sub-region 212 is different from the number of frames of images displayed per second in the second sub-region 214, that is, the refresh frequencies of the first sub-region 212 and the second sub-region 214 are different. In this way, when the display panel 20 is used to display dynamic images and static images at the same time, the sub-area used to display dynamic images can have a higher refresh frequency, and the sub-area used to display static images can have a lower refresh frequency, thereby ensuring the display effect of dynamic images and reducing the power consumption generated by the sub-area used to display static images.

[0071] In some embodiments, when the display panel 20 is operating, each gate driver 220 is configured to progressively scan the pixel units 2102 within the corresponding sub-region at a target refresh rate. The target refresh rate may be any one of a plurality of preset refresh rates. The preset refresh rate refers to a refresh rate that can be achieved by each sub-region of the display panel 20. The plurality of preset refresh rates may include at least two of 30 Hz, 60 Hz, 90 Hz, and 120 Hz.

[0072] Taking the example of a display panel 20 having multiple preset refresh rates including 60 Hz and 120 Hz, and the first sub-area 212 being used to display dynamic images and the second sub-area 214 being used to display static images, the following applies: when the display panel 20 is operating, the first gate driver 222 progressively scans the pixel units 2102 in the first sub-area 212 at a refresh rate of 120 Hz, so that the first sub-area 212 displays 120 frames of image per second; and the second gate driver 224 progressively scans the pixel units 2102 in the second sub-area 214 at a refresh rate of 60 Hz, so that the second sub-area 214 displays 60 frames of image per second. Generally, when the refresh rate of the first sub-area 212 and the refresh rate of the second sub-area 214 are different, that is, when the target refresh rate of the first gate driver 222 and the target refresh rate of the second gate driver 224 are different, the waveform of the timing signal input to the first gate driver 222 and the waveform of the timing signal input to the second gate driver 224 are different.

[0073] FIG6 is a circuit structure diagram of a pixel unit 2102 provided in an embodiment of the present application. As shown in FIG6 , the pixel unit 2102 may include a sub-pixel OLED and a pixel circuit 21022 for driving the sub-pixel OLED to emit light. In an embodiment of the present application, the sub-pixel OLED is an organic light emitting diode (OLED). The pixel circuit 21022 is a 2T1C circuit consisting of a transistor T1, a transistor T2, and a capacitor C1. Both the transistor T1 and the transistor T2 are thin film field effect transistors (TFT). The pixel unit 2102 operates when a scan signal SCAN and a data signal DATA are input simultaneously. When the pixel unit 2102 operates, the pixel circuit 2102 drives the sub-pixel OLED to emit light.

[0074] Specifically, when the pixel unit 2102 receives a scan signal SCAN, transistor T2 is turned on by the scan signal SCAN. At this point, the data signal DATA input to the pixel unit 2102 can be output via transistor T2 to the control electrode of transistor T1, turning on transistor T1. When transistor T1 is turned on, the sub-pixel OLED is turned on by a first voltage ELVDD and a second voltage ELVSS. The second voltage ELVSS is less than the first voltage ELVDD. During operation of the pixel unit 2102, the data signal DATA controls the conduction level of transistor T1, thereby controlling the brightness of the sub-pixel OLED. Capacitor C1 is used to maintain a stable voltage at the control electrode of transistor T1, thereby preventing voltage drift at the control electrode of transistor T1. It will be understood that the 2T1C pixel circuit 21022 is merely the basic circuitry of an organic light-emitting diode driver circuit. In other embodiments, the pixel circuit 21022 can also be a 7T1C circuit consisting of seven transistors and one capacitor, an 8T1C circuit consisting of eight transistors and one capacitor, or an 8T2C circuit consisting of eight transistors and two capacitors. These details will not be elaborated upon.

[0075] FIG7 is a schematic structural diagram of another display panel 20 provided in an embodiment of the present application. As shown in FIG7 , in some embodiments, the display panel 20 further includes a plurality of scan signal lines, a data driver 230, and a plurality of data signal lines. The gate driver 220 is used to output a scan signal. Each of the plurality of gate drivers 220 can be connected to the pixel unit 2102 in the corresponding sub-region via a scan signal line, thereby outputting a scan signal to the pixel unit 2102 via the scan signal line. In an embodiment of the present application, a row of pixel units 2102 in each of the plurality of sub-regions is connected to the corresponding gate driver 220 via a scan signal line. At the same time, a scan signal line is only connected to a row of pixel units 2102 in one sub-region. In this way, when the display panel 20 is in operation, each gate driver 220 can output a scan signal to any scan signal line, thereby scanning a row of pixel units 2102 in the corresponding sub-region connected to this scan signal line.

[0076] The data driver 230 is used to output data signals. The data driver 230 can be connected to the pixel unit 2102 via a data signal line, thereby outputting data signals to the pixel unit 2102 via the data signal line. In an embodiment of the present application, a column of pixel units 2102 in each of the multiple sub-regions is connected to the data driver 230 via a data signal line. At the same time, a data signal line is only connected to a column of pixel units 2102 in one of the multiple sub-regions. In this way, when the display panel 20 is operating, the data driver 230 can output a data signal to any data signal line, thereby outputting a data signal to the column of pixel units 2102 connected to this data signal line. When a scan signal is input into a scan signal line and a data signal line is input into a data signal line, a data signal can be written to the pixel unit 2102 connected to this scan signal line and this data signal line, and the sub-pixels in the pixel unit 2102 emit light.

[0077] The structure of the display panel 20 is explained in detail below based on three different division situations of the display area 210.

[0078] In a first possible implementation manner, the display area 210 of the display panel 20 is divided into a first sub-area 212 and a second sub-area 214 .

[0079] FIG7 shows a schematic diagram of the structure of the display panel 20 when the display area 210 of the display panel 20 is divided into a first sub-area 212 and a second sub-area 214. FIG8 is a schematic diagram of the division of the display area 210 provided in an embodiment of the present application. As shown in FIG7 and FIG8, the display area 210 can be divided into a first sub-area 212 and a second sub-area 214 arranged along the column direction. The first sub-area 212 and the second sub-area 214 can have different refresh rates. Thus, when the first sub-area 212 is used to display dynamic images and the second sub-area 214 is used to display static images, the first sub-area 212 can have a higher refresh rate under the scanning of the first gate driver 222, and the second sub-area 214 can have a lower refresh rate under the scanning of the second gate driver 224. When both the first sub-area 212 and the second sub-area 214 are used to display dynamic images or both are used to display static images, the first sub-area 212 and the second sub-area 214 can have the same refresh rate.

[0080] In the embodiment shown in FIG. 7 , the scan signal lines shown include G1 , G2 , G3 , G4 , and G5 ; the data signal lines shown include S1 a , S2 a . . . S10 a , and S1 b , S2 b . . . S10 b .

[0081] FIG9 is a schematic diagram illustrating the connections of pixel units 2102 in a first sub-region 212 according to an embodiment of the present application. As shown in FIG7 and FIG9 , along the direction opposite to the second direction Y, the first row of pixel units 2102 in the first sub-region 212 is connected to the first gate driver 222 via G1, and the second row of pixel units 2102 in the first sub-region 212 is connected to the first gate driver 222 via G2. G1 and G2 can each be connected to an output terminal of the first gate driver 222. Thus, when the first gate driver 222 is operating, it can sequentially output scan signals to G1 and G2. When the first gate driver 222 outputs a scan signal to G1, G1 can then output a scan signal to all pixel units 2102 in the first row of the first sub-region 212, thereby scanning all pixel units 2102 in the first row of the first sub-region 212. When the first gate driver 222 outputs a scan signal to G2 , G2 can output a scan signal to all pixel units 2102 in the second row in the first sub-region 212 , thereby scanning all pixel units 2102 in the second row in the first sub-region 212 .

[0082] Along the first direction X, the first column of pixel units 2102 in the first sub-area 212 is connected to the data driver 230 via S1a; the second column of pixel units 2102 in the first sub-area 212 is connected to the data driver 230 via S2a... The tenth column of pixel units 2102 in the first sub-area 212 is connected to the data driver 230 via S10a. When the first gate driver 222 outputs a scan signal to G1 and the data driver 230 outputs a data signal to S1a, S2a...S10a, the pixel unit 2102 located in the first row and first column of the first sub-area 212 can input the scan signal output by G1 and the data signal output by S1a, thereby causing the sub-pixel in this pixel unit 2102 to emit light; the pixel unit 2102 located in the first row and second column of the first sub-area 212 can input the scan signal output by G1 and the data signal output by S2a, thereby causing the sub-pixel in this pixel unit 2102 to emit light... The pixel unit 2102 located in the first row and tenth column of the first sub-area 212 can input the scan signal output by G1 and the data signal output by S10a, thereby causing the sub-pixel in this pixel unit 2102 to emit light. After G1 stops outputting scan signals, G2 begins outputting scan signals. At this point, the data signals output by data driver 230 to S1a, S2a, ..., S10a are input to the ten pixel units 2102 in the second row of first sub-region 212, thereby causing the sub-pixels in all pixel units 2102 in the second row of first sub-region 212 to emit light. After G1 and G2 sequentially output scan signals, first sub-region 212 displays a frame of image.

[0083] FIG10 is a schematic diagram illustrating the connections of pixel cells 2102 in a second sub-region 214 according to an embodiment of the present application. As shown in FIG7 and FIG10 , along the direction opposite to the second direction Y, the first row of pixel cells 2102 in the second sub-region 214 are connected to the second gate driver 224 via G3, the second row of pixel cells 2102 in the second sub-region 214 are connected to the second gate driver 224 via G4, and the third row of pixel cells 2102 in the second sub-region 214 are connected to the second gate driver 224 via G5. G3, G4, and G5 can each be connected to an output terminal of the second gate driver 224. Thus, when the second gate driver 224 is operating, it can sequentially output scan signals to G3, G4, and G5. When the second gate driver 224 outputs a scan signal to G3, G3 then outputs a scan signal to all pixel cells 2102 in the first row of the second sub-region 214, thereby scanning all pixel cells 2102 in the first row of the second sub-region 214. When the second gate driver 224 outputs a scan signal to G4, G4 can output a scan signal to all pixel units 2102 located in the second row in the second sub-region 214, thereby scanning all pixel units 2102 located in the second row in the second sub-region 214. When the second gate driver 224 outputs a scan signal to G5, G5 can output a scan signal to all pixel units 2102 located in the third row in the second sub-region 214, thereby scanning all pixel units 2102 located in the third row in the second sub-region 214.

[0084] Along the first direction X, the first column of pixel units 2102 in the second sub-area 214 is connected to the data driver 230 via S1b; the second column of pixel units 2102 in the second sub-area 214 is connected to the data driver 230 via S2b... The tenth column of pixel units 2102 in the second sub-area 214 is connected to the data driver 230 via S10b. When the second gate driver 224 outputs a scan signal to G3 and the data driver 230 outputs a data signal to S1b, S2b...S10b, the pixel unit 2102 located in the first row and first column of the second sub-area 214 can input the scan signal output by G3 and the data signal output by S1b, thereby causing the sub-pixel in this pixel unit 2102 to emit light; the pixel unit 2102 located in the first row and second column of the second sub-area 214 can input the scan signal output by G3 and the data signal output by S2b, thereby causing the sub-pixel in this pixel unit 2102 to emit light... The pixel unit 2102 located in the first row and tenth column of the second sub-area 214 can input the scan signal output by G3 and the data signal output by S10b, thereby causing the sub-pixel in this pixel unit 2102 to emit light. After G3 stops outputting scan signals, G4 starts outputting scan signals. At this point, the data signals output by the data driver 230 to S1b, S2b, ..., S10b can be input to the ten pixel units 2102 in the second row of the second sub-region 214, thereby causing the sub-pixels in all pixel units 2102 in the second row of the second sub-region 214 to emit light. After G4 stops outputting scan signals, G5 starts outputting scan signals. At this point, the data signals output by the data driver 230 to S1b, S2b, ..., S10b can be input to the ten pixel units 2102 in the third row of the second sub-region 214, thereby causing the sub-pixels in all pixel units 2102 in the third row of the second sub-region 214 to emit light. After G3, G4, and G5 sequentially output scan signals, the second sub-region 214 displays a frame of image.

[0085] In some embodiments, as shown in Figures 7, 9, and 10, the data driver 230 is further connected to the input terminals of the gate driver 220 (including the first gate driver 222 and the second gate driver 224). In this case, the timing signals required to be input to the gate driver 220 during operation can be output by the data driver 230.

[0086] FIG11 is a schematic diagram of the structure of another display panel 20 provided in an embodiment of the present application. As shown in FIG11 , in other embodiments, the display panel 20 may include two data drivers 230, namely, a first data driver 232 and a second data driver 234. A column of pixel units 2102 within the first sub-region 212 is connected to the first data driver 232 via a single data signal line. A column of pixel units 2102 within the second sub-region 214 is connected to the second data driver 234 via a single data signal line. Furthermore, a single data signal line is connected to only one column of pixel units 2102 within a sub-region.

[0087] Specifically, in the embodiment shown in FIG11 , the data signal lines include S1a, S2a, ..., S10a, and S1b, S2b, ..., S10b. Along a first direction X, the first column of pixel units 2102 in the first sub-region 212 is connected to the first data driver 232 via S1a; the second column of pixel units 2102 in the first sub-region 212 is connected to the first data driver 232 via S2a; and the tenth column of pixel units 2102 in the first sub-region 212 is connected to the first data driver 232 via S10a. In this case, when G1 and G2 output scan signals, the first data driver 232 outputs data signals to S1a, S2a, ..., S10a, causing the first sub-region 212 to display an image. Along the first direction X, the first column of pixel units 2102 in the second sub-region 214 is connected to the second data driver 234 via S1b; the second column of pixel units 2102 in the second sub-region 214 is connected to the second data driver 234 via S2b... The tenth column of pixel units 2102 in the second sub-region 214 is connected to the second data driver 234 via S10b. In this case, when G3, G4, and G5 output scan signals, the second data driver 234 outputs data signals to S1b, S2b, ..., S10b, so that the second sub-region 214 displays an image.

[0088] In some specific embodiments, the first data driver 232 may be located outside the display area 210 of the display panel 20 and disposed proximate to the first sub-region 212; the second data driver 234 may be located outside the display area 210 of the display panel 20 and disposed proximate to the second sub-region 214. For example, the first sub-region 212 and the second sub-region 214 are arranged along a column direction, with the first data driver 232 located on a side of the first sub-region 212 away from the second sub-region 214, and the second data driver 234 located on a side of the second sub-region 214 away from the first sub-region 212. In this manner, the first sub-region 212 proximate to the first data driver 232 is driven by the data signal output by the first data driver 232, while the second sub-region 214 proximate to the second data driver 234 is driven by the data signal output by the second data driver 234. This shortens the length of the data signal lines, thereby reducing losses caused by the data signal lines and improving the display brightness of the display panel 20.

[0089] Figure 12 is a schematic diagram of an application scenario of a display panel 20 provided in an embodiment of the present application. As shown in Figure 12, the picture displayed in the first sub-area 212 is the live video of "User 1", that is, the first sub-area 212 is used to display dynamic pictures; the picture displayed in the second sub-area 214 is the chat content and input box of other users (including "User 01", "User 02" and "User 03"), that is, the second sub-area 214 is used to display static pictures. In this case, the first sub-area 212 can be adjusted to a higher refresh frequency, and the second sub-area 214 can be adjusted to a lower refresh frequency. For example, the refresh frequency of the first sub-area 212 is adjusted to 120Hz, and the refresh frequency of the second sub-area 214 is adjusted to 60Hz.

[0090] FIG13 is a schematic diagram of another application scenario of the display panel 20 provided in an embodiment of the present application. As shown in FIG13 , the screen displayed in the first sub-area 212 is a text version of "News Headlines", that is, the first sub-area 212 is used to display static images; the screen displayed in the second sub-area 214 is a video version of "News Headlines", that is, the second sub-area 214 is used to display dynamic images. In this case, the second sub-area 214 can be adjusted to a higher refresh rate and the first sub-area 212 can be adjusted to a lower refresh rate. For example, the refresh rate of the first sub-area 212 can be adjusted to 60Hz, and the refresh rate of the second sub-area 214 can be adjusted to 120Hz.

[0091] In a second possible implementation manner, the display area 210 of the display panel 20 is divided into a first sub-area 212 , a second sub-area 214 and a third sub-area 216 .

[0092] FIG14 is a schematic diagram of the structure of another display panel 20 provided in an embodiment of the present application, and FIG15 is a schematic diagram of the division of another display area 210 provided in an embodiment of the present application. As shown in FIG14 and FIG15, the display area 210 can be divided into a first sub-area 212, a second sub-area 214, and a third sub-area 216. The first sub-area 212 and the second sub-area 214 are arranged in a column direction. The first sub-area 212 and the third sub-area 216 are arranged in a row direction, and the second sub-area 214 and the third sub-area 216 are arranged in a row direction. The first sub-area 212, the second sub-area 214, and the third sub-area 216 can have different refresh rates. In this way, when any one or two of the first sub-area 212, the second sub-area 214, and the third sub-area 216 display a dynamic image, and the other two or one of the first sub-area 212, the second sub-area 214, and the third sub-area 216 display a static image, the sub-area displaying the dynamic image can have a higher refresh rate under the scanning of the corresponding gate driver 220, and the sub-area displaying the static image can have a lower refresh rate under the scanning of the corresponding gate driver 220. When the first sub-area 212, the second sub-area 214, and the third sub-area 216 are all used to display dynamic images or all used to display static images, the first sub-area 212, the second sub-area 214, and the third sub-area 216 can have the same refresh rate.

[0093] In the embodiment shown in FIG. 14 , the scan signal lines shown include G1 , G2 . . . G10 ; the data signal lines shown include S1 a , S2 a . . . S5 a , S1 b , S2 b . . . S5 b , and S6 , S7 . . . S10 .

As shown in FIG14 and FIG16 , along the direction opposite to the second direction Y, the first row of pixel units 2102 in the first sub-region 212 is connected to the first gate driver 222 via G1, and the second row of pixel units 2102 in the first sub-region 212 is connected to the first gate driver 222 via G2. G1 and G2 can each be connected to an output terminal of the first gate driver 222. Thus, when the first gate driver 222 is operating, it can sequentially output scan signals to G1 and G2. When the first gate driver 222 outputs a scan signal to G1, G1 can then output a scan signal to all pixel units 2102 in the first row of the first sub-region 212, thereby scanning all pixel units 2102 in the first row of the first sub-region 212. When the first gate driver 222 outputs a scan signal to G2 , G2 can output a scan signal to all pixel units 2102 in the second row in the first sub-region 212 , thereby scanning all pixel units 2102 in the second row in the first sub-region 212 .

The pixel unit 2102 located in the first row and fifth column of the first sub-area 212 can input the scan signal output by G1 and the data signal output by S5a, thereby causing the sub-pixel in this pixel unit 2102 to emit light. After G1 stops outputting the scan signal, G2 starts outputting the scan signal. At this point, the data signals output by data driver 230 to S1a, S2a, ..., S5a are input to the five pixel units 2102 in the second row of first sub-region 212, thereby causing the sub-pixels in all pixel units 2102 in the second row of first sub-region 212 to emit light. After G1 and G2 sequentially output the scan signals, the first sub-region 212 displays a frame of image.

[0096] FIG17 is a schematic diagram illustrating the connection of pixel cells 2102 in a second sub-region 214 and a third sub-region 216 according to an embodiment of the present application.

G3, G4, and G5 can each be connected to an output terminal of the second gate driver 224. Thus, when the second gate driver 224 is in operation, it can sequentially output scan signals to G3, G4, and G5. When the second gate driver 224 outputs a scan signal to G3, G3 then outputs a scan signal to all pixel cells 2102 in the first row of the second sub-region 214, thereby scanning all pixel cells 2102 in the first row of the second sub-region 214. When the second gate driver 224 outputs a scan signal to G4, G4 can output a scan signal to all pixel units 2102 located in the second row in the second sub-region 214, thereby scanning all pixel units 2102 located in the second row in the second sub-region 214.

The pixel unit 2102 located in the first row and fifth column of the second sub-area 214 can input the scan signal output by G3 and the data signal output by S5b, thereby causing the sub-pixel in this pixel unit 2102 to emit light. After G3 stops outputting the scan signal, G4 starts outputting the scan signal. At this point, the data signals output by the data driver 230 to S1b, S2b, ..., S5b can be input to the five pixel units 2102 in the second row of the second sub-region 214, thereby causing the sub-pixels in all the pixel units 2102 in the second row of the second sub-region 214 to emit light. After G4 stops outputting the scan signal, G5 starts outputting the scan signal. At this point, the data signals output by the data driver 230 to S1b, S2b, ..., S5b can be input to the five pixel units 2102 in the third row of the second sub-region 214, thereby causing the sub-pixels in all the pixel units 2102 in the third row of the second sub-region 214 to emit light.

G6, G7, ..., G10 can each be connected to an output terminal of the third gate driver 226. In this way, when the third gate driver 226 is in operation, it can sequentially output scan signals to G6, G7, ..., G10. When the third gate driver 226 outputs a scan signal to G6, G6 can then output a scan signal to all pixel units 2102 in the first row of the third sub-region 216, thereby scanning all pixel units 2102 in the first row of the third sub-region 216. When the third gate driver 226 outputs a scanning signal to G7, G7 can output a scanning signal to all pixel units 2102 located in the second row in the third sub-region 216, thereby scanning all pixel units 2102 located in the second row in the third sub-region 216...

The pixel unit 2102 located in the first row and fifth column of the third sub-area 216 can input the scan signal output by G6 and the data signal output by S10, thereby causing the sub-pixel in this pixel unit 2102 to emit light. After G6 stops outputting the scan signal, G7 starts outputting the scan signal. At this point, the data signals output by the data driver 230 to S6, S7, ..., S10 can be input to the five pixel units 2102 in the second row of the third sub-region 216, thereby causing the sub-pixels in all the pixel units 2102 in the second row of the third sub-region 216 to emit light.

In this case, the timing signals required to be input to the gate driver 220 during operation can be output by the data driver 230.

[0101] FIG18 is a schematic diagram of the structure of another display panel 20 provided in an embodiment of the present application. As shown in FIG18 , in other embodiments, the display panel 20 may include two data drivers 230, namely, a first data driver 232 and a second data driver 234. A column of pixel units 2102 within the first sub-region 212 is connected to the first data driver 232 via a single data signal line. A column of pixel units 2102 within the second sub-region 214 and the third sub-region 216 is connected to the second data driver 234 via a single data signal line. Furthermore, a single data signal line is connected to only a column of pixel units 2102 within a sub-region.

[0102] Specifically, in the embodiment shown in FIG18 , the data signal lines shown include S1a, S2a…S5a, S1b, S2b…S5b, and S6, S7…S10. Along the first direction X, the first column of pixel units 2102 in the first sub-region 212 is connected to the first data driver 232 via S1a; the second column of pixel units 2102 in the first sub-region 212 is connected to the first data driver 232 via S2a…and the fifth column of pixel units 2102 in the first sub-region 212 is connected to the first data driver 232 via S5a. In this case, when G1 and G2 output scan signals, the first data driver 232 outputs data signals to S1a, S2a…S5a, causing the first sub-region 212 to display an image. Along the first direction X, the first column of pixel cells 2102 in the second sub-region 214 is connected to the second data driver 234 via S1b; the second column of pixel cells 2102 in the second sub-region 214 is connected to the second data driver 234 via S2b, and the fifth column of pixel cells 2102 in the second sub-region 214 is connected to the second data driver 234 via S5b. In this case, when G3, G4, and G5 output scan signals, the second data driver 234 outputs data signals to S1b, S2b, and S5b, causing the second sub-region 214 to display an image. Along the first direction X, the first column of pixel cells 2102 in the third sub-region 216 is connected to the second data driver 234 via S6; the second column of pixel cells 2102 in the third sub-region 216 is connected to the second data driver 234 via S7, and the fifth column of pixel cells 2102 in the third sub-region 216 is connected to the second data driver 234 via S10. In this case, when G6, G7, ..., G10 output scan signals, the second data driver 234 outputs data signals to S6, S7, ..., S10, so that the third sub-region 216 displays an image.

[0103] In some specific embodiments, the first data driver 232 may be located outside the display area 210 of the display panel 20 and disposed near the first sub-region 212; the second data driver 234 may be located outside the display area 210 of the display panel 20 and disposed near the second sub-region 214 and the third sub-region 216. In this manner, the first sub-region 212 near the first data driver 232 is driven by the data signal output by the first data driver 232; the second sub-region 214 and the third sub-region 216 near the second data driver 234 are driven by the data signal output by the second data driver 234. This shortens the length of the data signal lines, thereby reducing data signal line losses and improving the display brightness of the display panel 20. In other embodiments, the third sub-region 216 may also be driven by the first data driver 232, which will not be further described.

[0104] FIG19 is a schematic diagram of another application scenario of a display panel 20 provided in an embodiment of the present application. As shown in FIG19 , the first sub-area 212 and the second sub-area 214 are used to display game images, that is, the first sub-area 212 and the second sub-area 214 are used to display dynamic images; the third sub-area 216 is used to display the "chat" image, that is, the third sub-area 216 is used to display static images. In this case, the first sub-area 212 and the second sub-area 214 can be adjusted to a higher refresh rate, and the third sub-area 216 can be adjusted to a lower refresh rate. For example, the refresh rate of the first sub-area 212 and the second sub-area 214 can be adjusted to 120 Hz, and the refresh rate of the third sub-area 216 can be adjusted to 60 Hz.

The first sub-area 212, the second sub-area 214, the third sub-area 216, and the fourth sub-area 218 can have different refresh rates. In this way, when the display panel 20 is in operation, the sub-area displaying dynamic images can have a higher refresh rate when scanned by the corresponding gate driver 220, while the sub-area displaying static images can have a lower refresh rate when scanned by the corresponding gate driver 220.

At this point, the data signals output by data driver 230 to S1a, S2a, ..., S5a are input to the five pixel units 2102 in the second row of first sub-region 212, thereby causing the sub-pixels in all pixel units 2102 in the second row of first sub-region 212 to emit light. After G1 and G2 sequentially output the scan signals, the first sub-region 212 displays a frame of image.

[0110] Along the direction opposite to the second direction Y, the first row of pixel cells 2102 in the third sub-region 216 is connected to the third gate driver 226 via G6, and the second row of pixel cells 2102 in the third sub-region 216 is connected to the third gate driver 226 via G7. G6 and G7 can each be connected to an output terminal of the third gate driver 226. In this way, when the third gate driver 226 is in operation, it can sequentially output scan signals to G6 and G7. When the third gate driver 226 outputs a scan signal to G6, G6 can output a scan signal to all pixel cells 2102 in the first row of the third sub-region 216, thereby scanning all pixel cells 2102 in the first row of the third sub-region 216. When the third gate driver 226 outputs a scan signal to G7, G7 can output a scan signal to all pixel cells 2102 in the second row of the third sub-region 216, thereby scanning all pixel cells 2102 in the second row of the third sub-region 216.

G3, G4, and G5 can each be connected to an output terminal of the second gate driver 224. Thus, when the second gate driver 224 is operating, it can sequentially output scan signals to G3, G4, and G5. When the second gate driver 224 outputs a scan signal to G3, G3 then outputs a scan signal to all pixel cells 2102 in the first row of the second sub-region 214, thereby scanning all pixel cells 2102 in the first row of the second sub-region 214. When the second gate driver 224 outputs a scan signal to G4, G4 can output a scan signal to all pixel units 2102 in the second row of the second sub-region 214, thereby scanning all pixel units 2102 in the second row of the second sub-region 214.

The pixel unit 2102 located in the first row and fifth column of the second sub-area 214 can input the scan signal output by G3 and the data signal output by S5b, thereby causing the sub-pixel in this pixel unit 2102 to emit light. After G3 stops outputting the scan signal, G4 starts outputting the scan signal. At this point, the data signals output by the data driver 230 to S1b, S2b, ..., S5b can be input to the five pixel units 2102 in the second row of the second sub-region 214, thereby causing the sub-pixels in all the pixel units 2102 in the second row of the second sub-region 214 to emit light.

G8, G9, and G10 can each be connected to an output terminal of the fourth gate driver 228. In this way, when the fourth gate driver 228 is in operation, it can output scan signals to G8, G9, and G10 in sequence. When the fourth gate driver 228 outputs a scan signal to G8, G8 can output a scan signal to all pixel units 2102 in the first row of the fourth sub-region 218, thereby scanning all pixel units 2102 in the first row of the fourth sub-region 218.

After G8 stops outputting scan signals, G9 starts outputting scan signals. At this point, the data signals output by the data driver 230 to S6b, S7b, ..., S10b can be input to the five pixel units 2102 in the second row of the fourth sub-region 218, thereby causing the sub-pixels in all pixel units 2102 in the second row of the fourth sub-region 218 to emit light.

In this case, the timing signals required to be input to the gate driver 220 during operation can be output by the data driver 230.

[0117] FIG24 is a schematic diagram of the structure of another display panel 20 provided in an embodiment of the present application. As shown in FIG24 , in other embodiments, the display panel 20 may include two data drivers 230, namely, a first data driver 232 and a second data driver 234. Specifically, a column of pixel units 2102 within the first sub-region 212 and the third sub-region 216 are connected to the first data driver 232 via a single data signal line. A column of pixel units 2102 within the second sub-region 214 and the fourth sub-region 218 are connected to the second data driver 234 via a single data signal line. Furthermore, one of the multiple data signal lines is connected only to a column of pixel units 2102 in one of the multiple sub-regions.

[0118] Specifically, in the embodiment shown in FIG. 24 , the data signal lines shown include S1 a , S2 a . . . S10 a , and S1 b , S2 b . . . S10 b .

[0119] Along the first direction X, the first column of pixel cells 2102 in the first sub-region 212 is connected to the first data driver 232 via S1a; the second column of pixel cells 2102 in the first sub-region 212 is connected to the first data driver 232 via S2a; and the fifth column of pixel cells 2102 in the first sub-region 212 is connected to the first data driver 232 via S5a. In this case, when G1 and G2 output scan signals, the first data driver 232 outputs data signals to S1a, S2a, ..., S5a, causing the first sub-region 212 to display an image. Along the first direction X, the first column of pixel cells 2102 in the second sub-region 214 is connected to the second data driver 234 via S1b; the second column of pixel cells 2102 in the second sub-region 214 is connected to the second data driver 234 via S2b; and the fifth column of pixel cells 2102 in the second sub-region 214 is connected to the second data driver 234 via S5b. In this case, when G3, G4, and G5 output scan signals, the second data driver 234 outputs data signals to S1b, S2b, ..., S5b, causing the second sub-region 214 to display an image. Along the first direction X, the first column of pixel units 2102 in the third sub-region 216 is connected to the first data driver 232 via S6a; the second column of pixel units 2102 in the third sub-region 216 is connected to the first data driver 232 via S7a, ..., and the fifth column of pixel units 2102 in the third sub-region 216 is connected to the first data driver 232 via S10a. In this case, when G6 and G7 output scan signals, the first data driver 232 outputs data signals to S6a, S7a, ..., S10a, causing the third sub-region 216 to display an image. Along the first direction X, the first column of pixel units 2102 in the fourth sub-region 218 is connected to the second data driver 234 via S6b; the second column of pixel units 2102 in the fourth sub-region 218 is connected to the second data driver 234 via S7b, and so on. The fifth column of pixel units 2102 in the fourth sub-region 218 is connected to the second data driver 234 via S10b. In this case, when G8, G9, and G10 output scan signals, the second data driver 234 outputs data signals to S6b, S7b, ..., S10b, so that the fourth sub-region 218 displays an image.

[0120] In some specific embodiments, the first data driver 232 may be located outside the display area 210 of the display panel 20 and disposed near the first sub-area 212 and the third sub-area 216; the second data driver 234 may be located outside the display area 210 of the display panel 20 and disposed near the second sub-area 214 and the fourth sub-area 218. In this manner, the first sub-area 212 and the third sub-area 216 near the first data driver 232 are driven by the data signals output by the first data driver 232; and the second sub-area 214 and the fourth sub-area 218 near the second data driver 234 are driven by the data signals output by the second data driver 234. This shortens the length of the data signal lines, thereby reducing losses caused by the data signal lines and improving the display brightness of the display panel 20.

[0121] FIG25 is a schematic diagram of another application scenario of the display panel 20 provided in an embodiment of the present application. As shown in FIG25 , the first sub-area 212 and the second sub-area 214 are used to display the game screen, that is, the first sub-area 212 and the second sub-area 214 are used to display the dynamic screen; the third sub-area 216 and the fourth sub-area 218 are used to display the "chat" screen, that is, the third sub-area 216 and the fourth sub-area 218 are used to display the static screen. In this case, the first sub-area 212 and the second sub-area 214 can be adjusted to a higher refresh rate, and the third sub-area 216 and the fourth sub-area 218 can be adjusted to a lower refresh rate. For example, the refresh rate of the first sub-area 212 and the second sub-area 214 can be adjusted to 120 Hz, and the refresh rate of the third sub-area 216 can be adjusted to 60 Hz.

[0122] It is understood that in the three possible implementations described above, the number of rows and columns of pixel units 2102 shown should not constitute a limitation on the embodiments of the present application. Specifically, in the embodiments shown in Figures 7 to 24, the display panel 20 has 5 rows and 10 columns of pixel units 2102, that is, M is equal to 5 and N is equal to 10. In other embodiments, M may also be equal to 1280, 2560, 3840, etc., and N may be equal to 2400, 7200, etc. The embodiments of the present application do not limit this.

[0123] In some embodiments, when the display area 210 of the display panel 20 is divided into a first sub-area 212 and a second sub-area 214 arranged in a column direction as shown in Figures 7 and 8, the number of rows of pixel units 2102 in the first sub-area 212 can be smaller than the number of rows of pixel units 2102 in the second sub-area 214. In this case, if a dynamic image is played in the first sub-area 212, the power consumption generated by the second sub-area 214 used to display a static image can be reduced to a greater extent. In some other embodiments, the number of rows of pixel units 2102 in the first sub-area 212 can also be equal to the number of rows of pixel units 2102 in the second sub-area 214. It is understandable that those skilled in the art can set the number of rows and columns of pixel units 2102 in different sub-areas according to user needs, and this is not limited here.

[0124] In an embodiment of the present application, the display panel 20 includes a plurality of gate drivers 220 and a plurality of pixel units 2102. The plurality of pixel units 2102 are located within the display area 210. The display area 210 includes a plurality of sub-areas that do not overlap with each other. The plurality of gate drivers 220 correspond one-to-one to the plurality of sub-areas, and each gate driver 220 is used to scan the pixel units 2102 in the corresponding sub-area row by row, so that the corresponding sub-area displays an image. When the display panel 20 is working, the refresh frequencies of different sub-areas are different. In this way, when the display panel 20 is used to display dynamic images and static images at the same time, the sub-area used to display dynamic images can have a higher refresh frequency, and the sub-area used to display static images can have a lower refresh frequency, thereby ensuring the display effect of the dynamic image and reducing the power consumption generated by the sub-area used to display the static image.

[0125] An embodiment of the present application further provides an electronic device, comprising the display panel 20 as described in any one of the above embodiments.

[0126] Specifically, the display panel 20 includes multiple gate drivers 220 and multiple pixel units 2102. The "multiple" here refers to two or more integers. The display panel 20 has a display area 210. The multiple pixel units 2102 are arranged in a matrix of M rows and N columns within the display area 210. Here, M and N are both positive integers. When the display panel 20 is in operation, the multiple pixel units 2102 emit light to display an image. In the present application, the display area 210 of the display panel 20 includes multiple non-overlapping sub-areas. At least two of the multiple sub-areas are arranged along the column direction.

[0127] The number of gate drivers 220 is equal to the number of sub-regions, and the multiple gate drivers 220 correspond to the multiple sub-regions one-to-one. Each gate driver 220 in the multiple gate drivers 220 is connected to each pixel unit 2102 in the corresponding sub-region. When the display panel 20 is working, each gate driver 220 is used to scan the pixel units 2102 in the corresponding sub-region row by row. The pixel units 2102 emit light after being scanned by the gate driver 220. In this way, when the gate driver 220 scans all the pixel units 2102 in the corresponding sub-region once, the corresponding sub-region can display one frame of image. In the present application, when the display panel 20 is working, the refresh frequencies of different sub-regions in the multiple sub-regions are different. The refresh frequency of a sub-region refers to the number of times any pixel unit 2102 in the sub-region is scanned by the gate driver 220 per second. In other words, different sub-regions display different frames of images per second under the scanning of the corresponding gate driver 220.

[0128] FIG26 is a schematic diagram of the structure of an electronic device 30 provided in an embodiment of the present application. As shown in FIG26 , the display panel 20 further includes a plurality of scan signal lines, a data driver 230, and a plurality of data signal lines. The gate driver 220 is configured to output scan signals. Each of the plurality of gate drivers 220 can be connected to a pixel unit 2102 within a corresponding sub-region via a scan signal line, thereby outputting a scan signal to the pixel unit 2102 via the scan signal line. The data driver 230 is configured to output a data signal. The data driver 230 can be connected to the pixel unit 2102 via a data signal line, thereby outputting a data signal to the pixel unit 2102 via the data signal line. In an embodiment of the present application, a row of pixel units 2102 within each of the plurality of sub-regions is connected to the corresponding gate driver 220 via a scan signal line. Furthermore, a scan signal line is only connected to a row of pixel units 2102 within a sub-region. A column of pixel units 2102 within each of the plurality of sub-regions is connected to the data driver 230 via a data signal line. Meanwhile, one data signal line is only connected to one column of pixel units 2102 in one sub-region among the multiple sub-regions.

[0129] The data driver 230 can be connected to the input terminal of each gate driver 220, thereby outputting a timing signal to each gate driver 220. When the gate driver 220 is working, it is affected by the timing signal input from the input terminal, and multiple output terminals can output scan signals in sequence.

[0130] In an embodiment of the present application, the electronic device 30 further includes a system on chip (SOC). The data driver 230 of the display panel 20 is connected to the SOC. When the electronic device 30 is operating, the SOC can output image data to the display panel 20. The image data here includes a target grayscale value for each pixel unit 2102 in the display panel 20. When the data driver 230 is operating, on the one hand, it can be obtained based on the image data whether the picture to be displayed in each sub-area of ​​the display panel 20 is a dynamic picture or a static picture. On the other hand, it can be obtained based on the target grayscale value of each pixel unit 2102 in the image data. The voltage size of the data signal required to be input to each pixel unit 2102 can be obtained.

[0131] For example, if the result obtained by the data driver 230 based on the image data is that "the first sub-region 212 needs to display a dynamic image, and the second sub-region 214 needs to display a static image," the data driver 230 can output a first timing signal to the first gate driver 222. After receiving the first timing signal, the first gate driver 222 scans the pixel units 2102 in the first sub-region 212 row by row according to the first timing signal, so that the first sub-region 212 has a higher refresh rate, such as 120 Hz. The data driver 230 also outputs a second timing signal to the second gate driver 224. After receiving the second timing signal, the second gate driver 224 scans the pixel units 2102 in the second sub-region 214 row by row according to the second timing signal, so that the second sub-region 214 has a lower refresh rate, such as 60 Hz.

[0132] After the data driver 230 obtains the voltage size of the data signal required to be input to each pixel unit 2102 based on the target grayscale value of each pixel unit 2102 in the image data, it also outputs the data signal to the pixel unit 2102 that inputs the scan signal when the gate driver 220 (including the first gate driver 222 and the second gate driver 224) outputs the scan signal, thereby causing the sub-pixel in each pixel unit 2102 to emit light.

[0133] In an embodiment of the present application, the electronic device 30 includes a display panel 20 as in the above-mentioned embodiment. The display panel 20 includes a plurality of gate drivers 220 and a plurality of pixel units 2102. The plurality of pixel units 2102 are located in the display area 210. The display area 210 includes a plurality of sub-areas that do not overlap with each other. The plurality of gate drivers 220 correspond one-to-one to the plurality of sub-areas, and each gate driver 220 is used to scan the pixel units 2102 in the corresponding sub-area row by row, so that the corresponding sub-area displays an image. When the display panel 20 is working, the refresh frequencies of different sub-areas are different. In this way, when the display panel 20 is used to display dynamic images and static images at the same time, the sub-area used to display dynamic images can have a higher refresh frequency, and the sub-area used to display static images can have a lower refresh frequency, thereby ensuring the display effect of the dynamic images and reducing the power consumption generated by the sub-area used to display static images.
