[0063] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] Figure 1 is a schematic diagram of the structure of a display panel provided in an embodiment of this application. As shown in Figure 1, the display panel includes multiple scan lines, multiple pairs of data lines, and multiple sub-pixels defined by the intersection of the scan lines and data lines. The multiple sub-pixels are arranged in an array along the row and column directions, with each pixel row connected to a scan line and each pixel column connected to a pair of data lines.

[0065] Multiple pixel rows include a first pixel row and a second pixel row; each pair of data lines includes a first data line and a second data line; in each pixel column, the sub-pixels of the first pixel row are connected to the first data line, and the sub-pixels of the second pixel row are connected to the second data line;

[0066] Multiple pixel rows are divided into multiple subarrays arranged along the column direction. The multiple subarrays include a first subarray and a second subarray. The first subarray includes one or more first pixel rows, and the second subarray includes one or more second pixel rows. The first subarray and the second subarray are arranged alternately.

[0067] In some embodiments, the display panel includes multiple scan lines extending along the row direction. The display panel also includes multiple pairs of data lines, each pair including a first data line and a second data line, which extend along the column direction. Multiple sub-pixels are defined by the intersection of the scan lines and data lines. These sub-pixels are arranged in an array along the row and column directions to form a pixel array, which includes multiple pixel rows and multiple pixel columns. In Figure 1, the X-direction indicated by the arrow represents the row direction, and the Y-direction indicated by the arrow represents the column direction.

[0068] In some embodiments, each sub-pixel includes a thin-film transistor (TFT) and a pixel electrode. The TFT of a sub-pixel in each pixel row is connected to a scan line corresponding to that pixel row. The scan line can be connected to a display driving circuit. The display driving circuit sends an enable signal to the TFT of the sub-pixel in the corresponding pixel row via the scan line, causing the TFT to conduct. The display driving circuit can then enable the sub-pixel in the corresponding pixel row by sending an enable signal to the scan line. The connection between the TFT in the sub-pixel and the scan line is electrical, and the connection between the scan line and the display driving circuit is also electrical.

[0069] In some embodiments, the multiple pixel rows include a first pixel row and a second pixel row. The thin-film transistors (TFTs) of sub-pixels in the first pixel row are connected to a first data line corresponding to their respective pixel column, and the TFTs of sub-pixels in the second pixel row are connected to a second data line corresponding to their respective pixel column. That is, in each pixel column, the sub-pixels of the first pixel row are connected to the first data line, and the sub-pixels of the second pixel row are connected to the second data line. The first and second data lines can be connected to a display driving circuit, which can send data signals to the TFTs of the corresponding sub-pixels in the first pixel row via the first data line and to the TFTs of the corresponding sub-pixels in the second pixel row via the second data line, thereby charging the corresponding sub-pixels.

[0070] Specifically, the thin-film transistor of the sub-pixel in the first pixel row is electrically connected to the first data line, the thin-film transistor of the sub-pixel in the second pixel row is electrically connected to the second data line, and the first data line and the second data line are electrically connected to the display driving circuit respectively.

[0071] In some embodiments, the first subarray includes one or more first pixel rows, and each column of subpixels in the first subarray is connected to a first data line corresponding to its respective pixel column. The second subarray includes one or more second pixel rows, and each column of subpixels in the second subarray is connected to a second data line corresponding to its respective pixel column. Since multiple pixel rows are divided into first and second subarrays arranged alternately along the column direction, the connection order of subpixels and data lines in each pixel column is related to the arrangement order of the multiple subarrays.

[0072] For example, each first subarray includes a first pixel row, and each second subarray includes a second pixel row. The first and second subarrays are arranged alternately. Then, the connection order of the subpixels and data lines in each pixel column is "121212...", where "1" indicates that the subpixel is connected to the first data line, and "2" indicates that the subpixel is connected to the second data line. This is only an example for illustration, and the embodiments of this application do not limit this.

[0073] Currently, in some large-size, ultra-large-size, and high-resolution applications, the increased number and length of scan lines and data lines significantly shorten the effective charging time of subpixels when the scanning frequency remains constant. This is particularly true in applications with displays exceeding 100 inches and resolutions above 8K.

[0074] The display panel provided in this application embodiment has a pair of data lines connected to each pixel column. The sub-pixels in the first pixel row are driven by data signals sent from the first data line, and the sub-pixels in the second pixel row are driven by data signals sent from the second data line. In this way, the charging time of the first pixel row and the second pixel row can be increased accordingly, that is, the charging time of each row of sub-pixels is increased, thereby improving the pixel charging rate of the display panel and improving the display quality of the display panel.

[0075] In some embodiments, the display driving circuit includes a timing control circuit and a gate driving circuit. The gate driving circuit includes a GOA circuit disposed on at least one side bezel of the display panel; optionally, GOA circuits can be disposed on both side bezels. The GOA circuit on at least one side includes multiple cascaded GOA units, each GOA unit being connected to a scan line of the corresponding pixel row. Under the control of the timing control circuit, it can send an enable signal to the scan line, thereby enabling the sub-pixels in the corresponding pixel row. Therefore, embodiments of this application provide a display panel with a dual-side drive for scan lines and a dual data line structure, i.e., a 2G2D drive structure, which can improve the charging rate of the display panel, thereby improving the image quality performance of the display panel in application scenarios such as large size, ultra-large size, and high resolution.

[0076] Optionally, color resists of the same color are set in different subpixels of the pixel column.

[0077] In some embodiments, a color filter is provided in the sub-pixel. The color filter can filter the color of light so that the sub-pixel emits light of the color corresponding to the color filter. The color filter in different sub-pixels of each pixel column is the same color, so that the sub-pixels of that pixel column emit light of the same color. The color filter colors corresponding to different pixel columns can be the same or different, that is, different pixel columns can emit light of the same color or different colors of light. This application does not limit this.

[0078] In some embodiments, since the subpixels of a pixel column can emit light of the same color, the same data signal can be applied to the subpixels of different pixel rows. For example, in a multiplier display mode, applying the same data signal to two adjacent first pixel rows causes them to display the same image; or, applying the same data signal to two adjacent second pixel rows causes them to display the same image. This is merely an example, and the embodiments of this application do not impose any limitations on this.

[0079] Optionally, the pixel row includes a first sub-pixel, a second sub-pixel, and a third sub-pixel arranged periodically;

[0080] The color resist colors in the first, second, and third sub-pixels are different.

[0081] In some embodiments, each pixel row includes a first sub-pixel, a second sub-pixel, and a third sub-pixel arranged periodically along the row direction. The first, second, and third sub-pixels are connected to the scan lines corresponding to the pixel row. In different pixel rows, the first, second, and third sub-pixels are arranged in the same order, such that all sub-pixels in a pixel column are either the first sub-pixel, all are the second sub-pixels, or all are the third sub-pixels. Specifically, the arrangement order of the first, second, and third sub-pixels in the first pixel row is the same as that in the second pixel row. For example, in a pixel row, the first, second, and third sub-pixels are arranged sequentially from left to right, and this arrangement order is repeated periodically.

[0082] In some embodiments, the color resist in the first sub-pixel can be red, causing the first sub-pixel to emit red light. The color resist in the second sub-pixel can be green, causing the second sub-pixel to emit green light. The color resist in the third sub-pixel can be blue, causing the third sub-pixel to emit blue light. In this way, the first, second, and third sub-pixels can emit red, green, and blue light, respectively.

[0083] In some embodiments, different sub-pixels in each pixel column are provided with color resist of the same color. Each pixel row includes a periodically arranged first sub-pixel, a second sub-pixel, and a third sub-pixel. The color resist colors corresponding to the first, second, and third sub-pixels are red, green, and blue, respectively. In this way, multiple pixel columns with red, green, and blue colors arranged periodically can be formed. Since each pixel column is connected to a pair of first and second data lines, a frequency doubling display mode can be enabled for the first and second data lines respectively. The same data signal is charged to multiple rows of sub-pixels through the first and second data lines, thereby realizing frequency doubling display, increasing the charging time of the pixel row, and thus increasing the refresh rate of the display panel.

[0084] Optionally, the first data line and the second data line extend along the column direction, respectively;

[0085] The first data line corresponding to the same pixel column is located on the first side of the pixel column, and the second data line corresponding to the same pixel column is located on the second side of the pixel column.

[0086] The first side and the second side are two sides opposite each other regarding the pixel column.

[0087] In some embodiments, the scan lines extend along the row direction, and the first and second data lines extend along the column direction, respectively. Multiple scan lines and multiple pairs of data lines intersect to define multiple sub-pixels. Specifically, one scan line connects to a row of sub-pixels, a pair of data lines connects to a column of sub-pixels, multiple scan lines define multiple pixel rows, and multiple pairs of data lines define multiple pixel columns. That is, multiple sub-pixels are arranged in an array along the row and column directions.

[0088] In some embodiments, a pixel column corresponds to a pair of first data lines and second data lines, which extend along the column direction and can be located on opposite sides of the pixel column. Specifically, for the first and second data lines corresponding to the same pixel column, the first data line can be located on the first side of the pixel column, and the second data line can be located on the second side of the pixel column.

[0089] For example, the first data line and the second data line are located on the left and right sides of the pixel column. The first side can be the left side of the pixel column, and the second side can be the right side of the pixel column. This is only an example, and the embodiments of this application do not limit this.

[0090] In some embodiments, for a pixel column, the transistor of a sub-pixel in the first pixel row is connected to a first data line on the left side of the pixel column, and the transistor of a sub-pixel in the second pixel row is connected to a second data line on the right side of the pixel column. Thus, for sub-pixels in the first and second pixel rows, only the connection between the thin-film transistor of the sub-pixel and the first or second data line needs to be set, with minimal impact on the other structures of the sub-pixel.

[0091] Figure 2 is a schematic diagram of the pixel architecture of a display panel according to an embodiment of this application. As shown in Figure 2, the display panel has multiple scan lines including scan lines G1 to G5, a first data line such as data line 1 (Source1), and a second data line such as data line 2 (Source2). The gate of the thin-film transistor of the sub-pixel in each pixel row is connected to the scan line corresponding to that pixel row.

[0092] As shown in Figure 2, each first subarray includes a first pixel row, and each second subarray includes a second pixel row. The first and second subarrays are arranged alternately along the column direction, meaning that a first pixel row and a second pixel row are arranged alternately along the column direction. The subpixels in the first pixel row are connected to the first data line (data line 1) on the left side of their respective pixel column, and the subpixels in the second pixel row are connected to the second data line (data line 2) on the right side of their respective pixel column. Therefore, for a column of subpixels in the pixel architecture shown in Figure 2, the connection sequence of the thin-film transistors and data lines is "121212…".

[0093] However, for the display panel shown in Figure 2, since a first pixel row and a second pixel row are arranged alternately along the column direction, when two adjacent first pixel rows or two adjacent second pixel rows carry the same signal, there is a crossover situation. In some display modes, display abnormalities may occur. For example, in the frequency multiplication display mode, the upper and lower dividing lines of different colors are prone to color mixing and blurring.

[0094] As shown in Figure 2, the sub-pixels in rows 1 and 3, 2 and 4, and 5 and 7 display red, while the sub-pixels in rows 6 and 8, 9 and 11, and 10 and 12 display green. The dividing lines between the different colors are located in rows 5, 6, 7, and 8. Since rows 5 and 7 are red and rows 6 and 8 are green, the dividing lines appear yellow overall, indicating a color mixing problem.

[0095] Frequency doubling technology is a display driving method to achieve high refresh rates. In frequency doubling display mode, while ensuring the charging time of odd-numbered rows, even-numbered rows achieve data compensation through the pre-charge function of the odd-numbered rows above and below them. The charging time of even-numbered rows is doubled in the same way. Thus, with minimal resolution loss, the charging time of each pixel row can be doubled, thereby doubling the refresh rate.

[0096] Figure 3 is a timing diagram of a doubled refresh rate display mode. As shown in Figure 3, it illustrates the timing of the enable signals provided to scan lines G1-G12 and the data signals provided to each row of sub-pixels. In doubled refresh rate display mode, the display panel is scanned line by line, and adjacent rows of sub-pixels are charged with the same data signal. For example, in Figure 3, data 1 is charged to rows 1 and 2, and data 2 is charged to rows 3 and 4. This doubles the pixel row charging time, thereby doubling the refresh rate and achieving a high refresh rate display mode.

[0097] Optionally, at least one first subarray includes a plurality of first pixel rows, and / or at least one second subarray includes a plurality of second pixel rows.

[0098] In some embodiments, to avoid problems such as color bleeding at color boundaries, the first subarray and the second subarray, which are arranged alternately along the column direction of the display panel, may each include multiple first pixel rows in the first subarray and multiple second pixel rows in the second subarray. That is, by having at least one first subarray include multiple first pixel rows and / or at least one second subarray include multiple second pixel rows, display anomalies such as color bleeding and blurring at color boundaries on the display panel are improved, thereby enhancing the image quality of the display panel.

[0099] Specifically, at least one first subarray includes multiple first pixel rows. When multiple first pixel rows in the first subarray display an image of the same color, since there are no second pixel rows separating the multiple first pixel rows, display anomalies such as color bleeding at color boundaries can be avoided. Similarly, at least one second subarray includes multiple second pixel rows. When multiple second pixel rows in the second subarray display an image of the same color, since there are no first pixel rows separating the multiple second pixel rows, display anomalies such as color bleeding at color boundaries can be avoided.

[0100] In summary, by increasing the number of pixel rows included in the first subarray and / or the second subarray, the arrangement of the first and second pixel rows can be adjusted, thereby improving display abnormalities such as color bleeding and blurring caused by the intersection of the first and second pixel rows, and improving the display quality of the display panel in application scenarios such as the frequency multiplication display mode.

[0101] Optionally, each first subarray includes two first pixel rows, and each second subarray includes two second pixel rows.

[0102] In some embodiments, the pixel array may be two first pixel rows and two second pixel rows arranged alternately along the column direction. That is, the first subarray and the second subarray arranged alternately along the column direction each include two rows of subpixels, wherein each first subarray includes two first pixel rows and each second subarray includes two second pixel rows.

[0103] For example, the connection order of subpixels and data lines in each pixel column can be "11221122...", where "1" indicates that the subpixel is connected to the first data line, and "2" indicates that the subpixel is connected to the second data line. This is only an example, and the embodiments of this application do not limit this.

[0104] In this way, when the first pixel row in the first subarray displays an image of one color and the second pixel row in the second subarray displays an image of another color, the color mixing problem caused by the cross arrangement of the first and second pixel rows can be avoided, thus improving the display quality of the display panel.

[0105] Figure 4 is a second schematic diagram of the pixel architecture of a display panel according to an embodiment of this application. As shown in Figure 4, the display panel has multiple scan lines, such as scan lines G1 to G5, a first data line, such as data line 1, and a second data line, such as data line 2. The gate of the thin-film transistor of the sub-pixel in each pixel row is connected to the scan line corresponding to that pixel row.

[0106] As shown in Figure 4, each first subarray includes two first pixel rows, and each second subarray includes two second pixel rows. The first and second subarrays are arranged alternately along the column direction, that is, the two first pixel rows and the two second pixel rows are arranged alternately along the column direction. The sub-pixels in the first pixel row are connected to the first data line (data line 1) on the left side of their respective pixel column, and the sub-pixels in the second pixel row are connected to the second data line (data line 2) on the right side of their respective pixel column. Therefore, for a column of sub-pixels in the pixel architecture shown in Figure 4, the connection sequence of the thin-film transistors and data lines is "11221122…".

[0107] In some embodiments, sub-pixels in the same column are driven by data signals of the same polarity. The polarity of the data signals includes positive and negative polarity, meaning that the data signals transmitted by the first data line and the second data line corresponding to each pixel column are either both positive or both negative. However, the data signals corresponding to adjacent columns of sub-pixels have opposite polarities. For example, as shown in Figure 4, the first column of sub-pixels on the left is driven by a positive polarity data signal, while the adjacent second column of sub-pixels is driven by a negative polarity data signal. In Figure 4, the "+" sign indicates that the data signal is positive (i.e., the driving voltage is positive), and the "-" sign indicates that the data signal is negative (i.e., the driving voltage is negative).

[0108] Optionally, the first subarray arranged along the column direction is the first subarray; the first subarray includes a first pixel row;

[0109] After the first subarray, the second subarray is arranged alternately with the first subarray along the column direction, and each second subarray includes two second pixel rows, and each first subarray includes two first pixel rows.

[0110] In some embodiments, the pixel array may consist of a single first pixel row along the column direction, followed by two second pixel rows alternating with the two first pixel rows along the column direction. The single first pixel row is the first sub-array, meaning the first sub-array arranged along the column direction is the first sub-array, and the first sub-array includes one first pixel row. Then, the second sub-arrays alternate with the first sub-arrays, each including two rows of sub-pixels. Specifically, after one first pixel row, two second pixel rows alternate with the two first pixel rows along the column direction.

[0111] In some embodiments, if the first subarray arranged along the column direction is the first subarray, the first subarray includes a first pixel row, and according to the principle of alternating arrangement of the first subarray and the second subarray, the last subarray of the pixel array is the first subarray, and the last subarray includes a first pixel row.

[0112] For example, the connection order of subpixels and data lines in each pixel column can be "12211221...", where "1" indicates that the subpixel is connected to the first data line, and "2" indicates that the subpixel is connected to the second data line. This is only an example, and the embodiments of this application do not limit this.

[0113] In this way, when the first pixel row in the first subarray displays an image of one color and the second pixel row in the second subarray displays an image of another color, the color mixing problem caused by the cross arrangement of the first and second pixel rows can be avoided, thus improving the display quality of the display panel.

[0114] Figure 5 is a third schematic diagram of the pixel architecture of a display panel according to an embodiment of this application. As shown in Figure 5, the display panel has multiple scan lines, such as scan lines G1 to G5, a first data line, such as data line 1, and a second data line, such as data line 2. The gate of the thin-film transistor of the sub-pixel in each pixel row is connected to the scan line corresponding to that pixel row. Figure 5 also shows the polarity of the data signal corresponding to the sub-pixel through "+" and "-" signs. Similar to the pixel architecture shown in Figure 4, the polarity of the data signal corresponding to the sub-pixel in the same column of Figure 5 is the same, and the polarity of the data signal corresponding to the sub-pixel in adjacent columns is opposite.

[0115] As shown in Figure 5, the first pixel row is the first pixel row. The thin-film transistors of the subpixels in the first pixel row are connected to the first data line, i.e., data line 1. That is, the first subarray is the first subarray, which includes one first pixel row. After the first subarray, each second subarray includes two second pixel rows, and each first subarray includes two first pixel rows. The second subarrays and the first subarrays are arranged alternately along the column direction, that is, two second pixel rows and two first pixel rows are arranged alternately along the column direction.

[0116] As shown in Figure 5, the sub-pixels in the first pixel row are connected to the first data line (data line 1) on the left side of their respective pixel column, and the sub-pixels in the second pixel row are connected to the second data line (data line 2) on the right side of their respective pixel column. Therefore, for a column of sub-pixels in the pixel architecture shown in Figure 5, the connection sequence of the thin-film transistors and data lines is "12211221…".

[0117] This application provides a display device, which includes a display panel as described in the foregoing embodiments.

[0118] The display device provided in this application embodiment can achieve the same or similar effects as a display panel, which will not be described in detail here.

[0119] Figure 6 is a schematic diagram of the steps of a display driving method provided in an embodiment of this application. The display driving method is used to drive a display panel as described in the foregoing embodiment. As shown in Figure 6, the display driving method includes:

[0120] Step S1: Send an enable signal to the scan line and send data signals to the first data line and the second data line respectively, so that the overlapping part of the enable time period of the same group of first pixel rows is not less than 1 line scan time and the same data signal is received in the overlapping part of the enable time period, and the overlapping part of the enable time period of the same group of second pixel rows is not less than 1 line scan time and the same data signal is received in the overlapping part of the enable time period.

[0121] Each group of first pixel rows includes N adjacent first pixel rows, and each group of second pixel rows includes M adjacent second pixel rows; N and M are both integers greater than or equal to 2.

[0122] In some embodiments, adjacent first pixel rows may include consecutive rows of first pixels, and adjacent second pixel rows may include consecutive rows of second pixels. For example, in the pixel architecture shown in FIG4 or FIG5, two first pixel rows in the first subarray are two adjacent first pixel rows, and two second pixel rows in the second subarray are two adjacent second pixel rows.

[0123] Alternatively, adjacent first pixel rows may include first pixel rows arranged with one or more second pixel rows spaced apart, and adjacent second pixel rows may include second pixel rows arranged with one or more first pixel rows spaced apart. For example, in the pixel architecture shown in Figure 2, rows 1 and 3 are two adjacent first pixel rows, and rows 2 and 4 are two adjacent first pixel rows. In this case, the adjacency relationship is adjacent with one row spaced apart. This is only an example for illustration, and the embodiments of this application do not limit this.

[0124] In some embodiments, the display driving circuit of the display panel can serve as the execution body of the display driving method. To improve the charging time of pixel rows, the display driving circuit can increase the charging time of the first pixel rows by activating a group of first pixel rows and applying the same data signal, and increase the charging time of the second pixel rows by activating a group of second pixel rows and applying the same data signal, thereby improving the charging rate of the pixel rows and increasing the refresh rate of the display panel.

[0125] Specifically, an enable signal is sent to the scan line, causing the sub-pixels of the pixel rows connected by the scan line to be enabled. The enabling periods of the same first pixel row overlap, with the overlapping period being no less than one line scan duration. Similarly, the enabling periods of the same second pixel row overlap, with the overlapping period also being no less than one line scan duration (e.g., 1.5 times, 2 times, 3 times, etc., which is not limited here). This ensures that the duration for which the same first pixel row and the same second pixel row are simultaneously enabled is no less than 1 hour, and vice versa. Here, the line scan duration represents the time required for the enable signal to enable one row of sub-pixels, which can be denoted as 1 hour.

[0126] Specifically, data signals are sent to the first data line and the second data line respectively. The same data signal can be applied to the same group of first pixel rows through the first data line, so that the same group of first pixel rows receives the same data signal in the overlapping part of the opening period. The same data signal can also be applied to the same group of second pixel rows through the second data line, so that the same group of second pixel rows receives the same data signal in the overlapping part of the opening period.

[0127] In this way, when a group of first pixel rows simultaneously in the active state receives the same data signal, the effective charging time of the sub-pixels increases, thus increasing the charging time of the first pixel row and improving the charging rate of the sub-pixels within that row. The same principle applies to a group of second pixel rows; when a group of second pixel rows simultaneously in the active state receives the same data signal, the effective charging time of the sub-pixels increases, thus increasing the charging time of the second pixel row and improving the charging rate of the sub-pixels within that row. In applications involving large, ultra-large, and high-resolution displays, this ensures a high pixel charging rate and increases the refresh rate of the display panel.

[0128] Optionally, step S1 may include the following sub-steps:

[0129] Sub-step A1: Alternately scan a group of first pixel rows and a group of second pixel rows, so that the overlapping part of the opening time period of the same group of first pixel rows is not less than 1 line scan time, the overlapping part of the opening time period of the same group of second pixel rows is not less than 1 line scan time, and the time difference between the first sending time corresponding to adjacent groups of first pixel rows and groups of second pixel rows is not less than 1 line scan time.

[0130] In addition, the same data signal is sent to the first data line corresponding to a group of first pixel rows and the same data signal is sent to the second data line corresponding to a group of second pixel rows, so that the time difference between the second transmission times corresponding to adjacent groups of first pixel rows and groups of second pixel rows is not less than twice the row scan duration; wherein, the first transmission time is the time when the turn-on signal is sent to the scan line and the second transmission time is the time when the data signal is sent to the data line.

[0131] In some embodiments, excessive delays in the activation times of the same group of first pixel rows can lead to significant differences in charging times between different first pixel rows within the same group, and similar problems may exist for the same group of second pixel rows. To reduce the activation delays of the same group of pixel rows and decrease the differences in charging times, the row scanning order can be adjusted so that the activation time of one of the adjacent groups of first pixel rows and second pixel rows is advanced, and the corresponding data signal is also advanced synchronously.

[0132] Specifically, a group of first pixel rows is scanned to enable the first pixel rows within the same group, and the overlap of the enabling time periods of the first pixel rows within the same group is not less than 1 row scan time. Then, a group of second pixel rows is scanned to enable the second pixel rows within the same group, and the overlap of the enabling time periods of the second pixel rows within the same group is not less than 1H. When scanning a group of first pixel rows, the first pixel rows within the same group can be enabled simultaneously or row by row; similarly, when scanning a group of second pixel rows, the second pixel rows within the same group can be enabled simultaneously or row by row. This embodiment of the application does not impose any restrictions on this.

[0133] Furthermore, there is a time difference between the first transmission times corresponding to adjacent sets of first pixel rows and sets of second pixel rows. For example, a set of first pixel rows may start before a set of second pixel rows, or vice versa. This application embodiment does not impose any limitations on this. The first transmission time is the time when an enable signal is sent to the scan line, and the time difference between the first transmission times corresponding to adjacent sets of first pixel rows and sets of second pixel rows is less than 1 hour.

[0134] Specifically, the same data signal is sent to the first data line corresponding to a group of first pixel rows, so that the same group of first pixel rows receives the same data signal within the overlapping portion of the opening time period. Similarly, the same data signal is sent to the second data line corresponding to a group of second pixel rows, so that the same data signal is received within the overlapping portion of the opening time period of the same group of second pixel rows. The second transmission time is the time when the data signal is sent to the data line, and the time difference between the second transmission times corresponding to adjacent groups of first pixel rows and groups of second pixel rows is not less than 2H.

[0135] Optionally, alternatingly scanning a set of first pixel rows and a set of second pixel rows includes:

[0136] Each scanned group of first pixel rows is scanned line by line, and each scanned group of second pixel rows is scanned line by line, so that the overlapping part of the opening time period of the same group of first pixel rows is not less than 1 line scan time, the overlapping part of the opening time period of the same group of second pixel rows is not less than 1 line scan time, and the time difference between the first transmission time corresponding to adjacent groups of first pixel rows and groups of second pixel rows is not less than 1 line scan time.

[0137] In some embodiments, each scanned group of first pixel rows is performed line by line. The time difference between the first transmission times corresponding to two consecutively distributed first pixel rows within the same group can be 1H, and the overlap of the opening periods of the same group of first pixel rows is not less than 1H. Similarly, each scanned group of second pixel rows is performed line by line. The time difference between the first transmission times corresponding to two consecutively distributed second pixel rows within the same group can be 1H, and the overlap of the opening periods of the same group of second pixel rows is not less than 1H.

[0138] In this way, when the pixel array is driven by the GOA circuit located on both sides of the display panel, it is only necessary to adjust the order of the turn-on signals output by the GOA circuit in the frequency multiplication mode, scan a group of first pixel rows line by line and then scan a group of second pixel rows line by line, which can reduce the control difficulty and improve practicality.

[0139] Figure 7 is a timing diagram of a display driving method provided in an embodiment of this application. Taking the pixel architecture shown in Figure 2 as an example, as shown in Figure 7, an enable signal can be sequentially sent to the first pixel row connected by scan lines G1 and G3, and a data signal can be sent to the first data line (data line 1) connected to the first pixel row, so that the two first pixel rows receive the same data signal. Then, an enable signal is sequentially sent to the second pixel row connected by scan lines G2 and G4, and a data signal is sent to the second data line (data line 2) connected to the second pixel row, so that the two second pixel rows receive the same data signal.

[0140] As shown in Figure 7, taking the pixel architecture shown in Figure 2 as an example, in this embodiment, the Gout timing of the GOA circuit is set to 1→3→2→4→5→7→6→8…, and the data signal of data line 1 is synchronously advanced with the Gout signal of rows 3, 7, 11… At this time, the delay between the opening times of rows 1, 5, 9… and rows 3, 7, 11… is reduced. Under the premise that the charging time of rows 3, 7, 11… remains unchanged, the charging time of rows 1, 5, 9… is increased, which can effectively improve the pixel charging rate, thereby improving the image quality of the display panel. Referring to Figure 7, for example, the data signal in data line 1 for 2 hours is the same, and the data signal in data line 2 for 2 hours is also the same. For example, in the timing sequences G1 and G3 in Figure 7, the timing duration of the data signal charged to data line 1 in the non-overlapping portion can be 1H. The frequency multiplication technology of this invention can make the data signal corresponding to data line 1 charged in row G3 greater than 1H, for example, 2H, thereby improving the charging rate of the display panel. Similarly, in the timing sequences G2 and G4, the timing duration of the data signal charged to data line 2 in the non-overlapping portion can be 1H. The frequency multiplication technology of this invention can make the data signal corresponding to data line 2 charged in row G4 greater than 1H, for example, 2H. In other embodiments, such as in Figures 8, 9, 13, 14, and 15, the data signals in data line 1 that are continuously greater than 1H are the same, and the data signals in data line 2 that are continuously greater than 1H are the same. For example, the data signals in data line 1 that are continuously greater than 2H are the same, and the data signals in data line 2 that are continuously greater than 2H are the same. The non-overlapping time of the pixel row timing sequence charging the same data signal can be 1H, which is not limited here.

[0141] Figure 8 is a second timing diagram of a display driving method provided in an embodiment of this application. Taking the pixel architecture shown in Figure 4 as an example, as shown in Figure 8, an enable signal can be sequentially sent to the first pixel row connected by scan lines G1 and G2, and a data signal can be sent to the first data line (data line 1) connected to the first pixel row, so that the two first pixel rows receive the same data signal. Then, an enable signal is sequentially sent to the second pixel row connected by scan lines G3 and G4, and a data signal is sent to the second data line (data line 2) connected to the second pixel row, so that the two second pixel rows receive the same data signal. As shown in Figure 8, taking the pixel architecture shown in Figure 4 as an example, this embodiment sets the Gout timing of the GOA circuit to 1→2→3→4…, increasing the charging time of odd-numbered rows, which can effectively improve the pixel charging rate, thereby improving the image quality of the display panel.

[0142] Optionally, sending an enable signal to the scan line before alternately scanning a set of first pixel rows and a set of second pixel rows further includes:

[0143] Scan the first pixel row in the first subarray to open the first pixel row in the first subarray;

[0144] Before sending a data signal to the first data line corresponding to a group of first pixel rows and sending a data signal to the second data line corresponding to a group of second pixel rows, sending data signals to the first data line and the second data line respectively also includes:

[0145] Send a data signal to the first data line corresponding to the first pixel row in the first subarray.

[0146] In some embodiments, if the first subarray arranged along the column direction is a first subarray, and the first subarray includes a first pixel row, then the first pixel row in the first subarray is first scanned to enable the first pixel row in the first subarray, and a data signal is sent to the first data line corresponding to the first pixel row in the first subarray. Then, the operation of alternately scanning a set of second pixel rows and a set of first pixel rows is performed, and the same data signal is sent to the second data line corresponding to the set of second pixel rows and the same data signal is sent to the first data line corresponding to the set of first pixel rows.

[0147] Figure 9 is a third timing diagram of a display driving method provided in this application embodiment. Taking the pixel architecture shown in Figure 5 as an example, as shown in Figure 9, an enable signal can be sent to scan line G1 first and a data signal can be sent to the first data line. Then, an enable signal can be sent to the second pixel row connected by scan lines G2 and G3 in sequence, and a data signal can be sent to the second data line (data line 2) connected to the second pixel row, so that the two second pixel rows receive the same data signal. Then, an enable signal can be sent to the first pixel row connected by scan lines G4 and G5 in sequence, and a data signal can be sent to the first data line (data line 1) connected to the first pixel row, so that the two first pixel rows receive the same data signal. As shown in Figure 9, taking the pixel architecture shown in Figure 5 as an example, this embodiment sets the Gout timing of the GOA circuit to 1→2→3→4→5…, increasing the charging time of even-numbered rows, which can effectively improve the pixel charging rate, thereby improving the image quality of the display panel.

[0148] Optionally, step S1 may further include the following sub-steps:

[0149] In sub-step A2, in the first display mode, an enable signal is sent to the scan line, and data signals are sent to the first data line and the second data line respectively, so that the overlapping portion of the enable time of the same group of first pixel rows is not less than 1 line scan time, and the same data signal is received in the overlapping portion of the enable time; and the overlapping portion of the enable time of the same group of second pixel rows is not less than 1 line scan time, and the same data signal is received in the overlapping portion of the enable time.

[0150] The display driver method also includes:

[0151] Step S2: In the second display mode, a first pixel row and a second pixel row are scanned alternately, and data signals are sent to the first data line and the second data line respectively, so that the first pixel row is turned on and receives the data signal corresponding to the first pixel row, and the second pixel row is turned on and receives the data signal corresponding to the second pixel row.

[0152] In some embodiments, the first display mode can be a frequency-doubled display mode. In this mode, the same data signal can be applied to adjacent rows of sub-pixels, increasing the charging time of the pixel rows and thus improving the refresh rate of the display panel. The second display mode can be a conventional display mode. In the first display mode, the pixel array is driven by data signals transmitted through dual data lines, namely the first data line and the second data line, thereby improving the pixel charging rate. In the first display mode, there are no restrictions on the data signals applied to adjacent rows of sub-pixels; the data signals can be the same or different.

[0153] In some embodiments, the display driving circuit can determine whether to use a first display mode or a second display mode based on the display data sent by the host. For example, when the amount of row data in the display data is less than half the amount of column data, the first display mode can be used, while when the amount of row data and column data in the display data is normal, the second display mode can be used. This is merely an example, and the embodiments of this application do not impose any limitations on it.

[0154] In some embodiments, the display panel employs a dual-side drive for scan lines and a dual-data-line structure, i.e., a 2G2D drive structure. GOA circuits are provided on both sides of the display panel, with each GOA circuit including multiple cascaded GOA units. Each GOA unit is connected to the scan line of the corresponding pixel row. Each pixel column is connected to a pair of data lines; specifically, the sub-pixels of the first pixel row in each pixel column are connected to the first data line, and the sub-pixels of the second pixel row are connected to the second data line.

[0155] Figure 10 is a timing diagram of a display driving method provided in this application in a second display mode. Taking the pixel architecture shown in Figure 2 as an example, as shown in Figure 10, enable signals can be sent sequentially to scan lines G1 to G4, and data signals can be sent to the first data line and the second data line respectively, thereby scanning the pixel array line by line, so that each pixel row receives the corresponding data signal to achieve a normal 2G2D display effect.

[0156] Figure 11 is a second timing diagram of a display driving method provided in this application in a second display mode. Taking the pixel architecture shown in Figure 4 as an example, as shown in Figure 11, the Gout timing of the GOA circuit in the second display mode is set to 1→3→2→4→5→7→6→8…… to achieve a normal 2G2D display effect.

[0157] Figure 12 is a third timing diagram of a display driving method provided in this application in the second display mode. Taking the pixel architecture shown in Figure 5 as an example, as shown in Figure 12, the Gout timing of the GOA circuit in the second display mode is set to 1→2→4→3→5→6→8→7…… to achieve a normal 2G2D display effect.

[0158] Optionally, step S1 may include the following sub-steps:

[0159] Sub-step A3: Alternately scan a first pixel row and a second pixel row so that the overlapping portion of the opening time of the same group of first pixel rows is not less than 1 row scan time, and the overlapping portion of the opening time of the same group of second pixel rows is not less than 1 row scan time.

[0160] In addition, the same data signal is sent to the first data line corresponding to a group of first pixel rows and the same data signal is sent to the second data line corresponding to a group of second pixel rows, so that the time difference between the second transmission times corresponding to adjacent groups of first pixel rows and groups of second pixel rows is not less than 1 line scan duration.

[0161] In some embodiments, when switching from the second display mode to the first display mode, the row scanning order can remain unchanged, and the same data signal can be sent to the first data line corresponding to a group of first pixel rows and the same data signal can be sent to the second data line corresponding to a group of second pixel rows. This reduces timing complexity and simplifies the implementation of frequency multiplication display. For example, the Gout timing can be maintained in the first display mode as in the second display mode. Taking the pixel architecture shown in Figure 2 as an example, the Gout timing in the second display mode can be set to 1→2→3→4…, that is, scanning the pixel array row by row.

[0162] Figure 13 is a timing diagram of a display driving method provided in an embodiment of this application in a first display mode. Taking the pixel architecture shown in Figure 2 as an example, as shown in Figure 13, the Gout timing of the GOA circuit is set to 1→2→3→4……, and a data signal is sent to the first data line (data line 1) connected to the first pixel row, so that the two first pixel rows receive the same data signal, and a data signal is sent to the second data line (data line 2) connected to the second pixel row, so that the two second pixel rows receive the same data signal.

[0163] Figure 14 is a second timing diagram of a display driving method provided in an embodiment of this application in a first display mode. Taking the pixel architecture shown in Figure 4 as an example, as shown in Figure 14, the Gout timing of the GOA circuit is set to 1→3→2→4→5→7→6→8……, and a data signal is sent to the first data line (data line 1) connected to the first pixel row, so that the two first pixel rows receive the same data signal, and a data signal is sent to the second data line (data line 2) connected to the second pixel row, so that the two second pixel rows receive the same data signal.

[0164] Optionally, before sub-step A3, step S1 further includes the following sub-steps:

[0165] Sub-step A4: Scan the first pixel row in the first sub-array to enable the first pixel row in the first sub-array; and send a data signal to the first data line corresponding to the first pixel row in the first sub-array.

[0166] In some embodiments, if the first subarray arranged along the column direction in the pixel array is a first subarray, and the first subarray includes a first pixel row, then before alternately scanning a first pixel row and a second pixel row, sending the same data signal to the first data line corresponding to a group of first pixel rows, and sending the same data signal to the second data line corresponding to a group of second pixel rows, firstly, one first pixel row in the first subarray is scanned and the corresponding data signal is applied. Then, alternating scanning is performed along the column direction in the order of scanning a second pixel row and then scanning a first pixel row, and the same data signal is applied to the same group of second pixel rows and the same data signal is applied to the same group of first pixel rows. In this way, the scanning of the entire pixel array is completed, and the pixel array is driven to display the image.

[0167] Specifically, an enable signal is sent to the scan line corresponding to the first pixel row in the first subarray to enable the first pixel row in the first subarray, and a data signal is sent to the first data line corresponding to the first pixel row in the first subarray so that the first pixel row in the first subarray receives the corresponding data signal.

[0168] Figure 15 is a third timing diagram of a display driving method provided in the first display mode according to an embodiment of this application. Taking the pixel architecture shown in Figure 5 as an example, as shown in Figure 15, the Gout timing of the GOA circuit is set to 1→2→4→3→5→6→8→7……, and firstly, a data signal is sent to the first data line (i.e., data line 1) connected to the first pixel row corresponding to the scan line G1. Then, a data signal is sent to the second data line (i.e., data line 2) connected to a group of second pixel rows, so that the two second pixel rows receive the same data signal, and a data signal is sent to the first data line (i.e., data line 1) connected to a group of first pixel rows, so that the two first pixel rows receive the same data signal.

[0169] The display driving method provided in this application embodiment can drive the display panel with the 2G2D driving structure in the aforementioned embodiment, and can apply the frequency multiplication display mode to the display panel with the 2G2D driving structure to improve the image quality performance of the display panel in application scenarios such as large size, ultra-large size, and high resolution.

[0170] This application provides a display driving method for display panels with various pixel architectures as described in the previous embodiments. By sending an enable signal to the scan lines and data signals to the first and second data lines respectively, the overlapping portion of the enable time periods of the same group of first pixel rows is not less than one line scan duration, and the same data signal is received within the overlapping portion of the enable time periods. Similarly, the overlapping portion of the enable time periods of the same group of second pixel rows is not less than one line scan duration, and the same data signal is received within the overlapping portion of the enable time periods. Since each group of first pixel rows includes N adjacent first pixel rows, and each group of second pixel rows includes M adjacent second pixel rows, where N and M are both integers greater than or equal to 2, the same data signal can be supplied to multiple pixel rows of the display panel, increasing the charging time of the pixel rows and thus improving the refresh rate of the display panel.
