Abstract

A display panel (20), a driving method, and a display device (10), relating to the field of display. First pixel columns and multiple data lines (DL) and scanning lines are provided in a display area (AA area) of the display panel (20). Each first pixel column comprises sub-pixels (A, B) of at least two colors distributed at intervals in a column direction. Sub-pixels (A, B) of the same color in each first pixel column are connected to the same DL, and sub-pixels (A, B) of the same color in at least two first pixel columns reuse the same DL. Thus, each DL only outputs a driving voltage signal for sub-pixels (A, B) of one color, thereby greatly reducing the power loss during voltage flipping caused by a large difference in driving voltage signals for sub-pixels (A, B) of different colors.

Description

Display panel, display panel driving method and display device

[0001] This application claims priority to Chinese Patent Application No. 202410692491.4, filed on May 30, 2024, entitled "Display Panel, Driving Method for Display Panel and Display Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of display technology, and particularly relates to a display panel, a driving method for the display panel, and a display device. Background Technology

[0003] In the AMOLED display field, the display panel contains sub-pixels of various colors and multiple crisscrossing data lines and scan lines within its display area. These data lines and scan lines drive the sub-pixels to emit light. The driving voltage signal on the same data line needs to undergo corresponding voltage flips during the intervals between the scanning and selection of each row of sub-pixels. This voltage flipping process requires a certain amount of time and consumes power. For example, when the voltage signals corresponding to the grayscale values ​​of different sub-pixels on the same data line differ significantly, the voltage flipping process on the data line will cause substantial power loss, which is detrimental to energy conservation. Summary of the Invention

[0004] This application provides a display panel, a driving method for the display panel, and a display device, with the aim of reducing the power loss of the display panel.

[0005] In a first aspect, this application provides a display panel, comprising: a first pixel column, multiple data lines, and multiple scan lines disposed within a display area;

[0006] The first pixel column includes sub-pixels of at least two colors that are spaced apart in the column direction;

[0007] Subpixels of the same color in each first pixel column are connected to the same data line, and at least two subpixels of the same color in the first pixel column reuse the same data line.

[0008] In some embodiments, the display panel further includes a second pixel column, wherein the first pixel column and the second pixel column are spaced apart in the row direction, and the second pixel column includes sub-pixels of the same color.

[0009] In some embodiments, in two adjacent first pixel columns, at least some sub-pixels of the same color reuse the same data line.

[0010] In some embodiments, the pixels are arranged such that, in the odd-numbered first pixel column, the sub-pixels of the first color and the second color are alternately arranged, and in the even-numbered first pixel column, the sub-pixels of the second color and the first color are alternately arranged; the second pixel column consists entirely of sub-pixels of the third color.

[0011] In some embodiments, the specific connection method for multiplexing at least some sub-pixels of the same color in two adjacent first pixel columns using the same data line can be:

[0012] The first color sub-pixel in the 2mth first pixel column is connected to the data line of the first color sub-pixel in the 2m-1th first pixel column through the first connection line, and the second color sub-pixel in the 2m+1th first pixel column is connected to the data line of the second color sub-pixel in the 2mth first pixel column through the second connection line.

[0014] The first and second connecting lines extend along the direction of the pixel row, and m is a positive integer.

[0015] In some embodiments, the second data line of the second color sub-pixel in the first first pixel column of the display area is connected only to the second color sub-pixel in the first first pixel column, and the second data line of the second color sub-pixel in the last first pixel column is connected only to the second color sub-pixel in the last first pixel column.

[0016] Alternatively, the first data line of the first color subpixel in the first first pixel column of the display area is connected only to the first color subpixel of the first first pixel column, and the first data line of the first color subpixel in the last first pixel column is connected only to the first color subpixel of the last first pixel column.

[0017] In some embodiments, the first connection line connecting the subpixel of the first color in the last first pixel column in the display area to its data line needs to cross the data line of the adjacent second pixel column; or, the first connection line does not cross the data line of the adjacent second pixel column.

[0018] In some embodiments, the aforementioned first data line is connected via a third connection line and / or a fourth connection line;

[0019] Alternatively, the aforementioned second data line can be connected via a third and / or fourth connecting line;

[0020] The third and fourth connecting lines extend along the direction of the pixel row, with the third connecting line located at the driving end of the display area and the fourth connecting line located at the end of the display area opposite to the driving end.

[0021] In some embodiments, the third connecting line is arranged on the same layer as the scan line, and the fourth connecting line is arranged on the same layer as the data line or scan line.

[0022] In some embodiments, in the first three first pixel columns within the display area, the sub-pixels of the second color in the first and third first pixel columns are connected to the data line corresponding to the second first pixel column via a second connecting line, and the data line of the sub-pixels of the second color in the last first pixel column is only connected to the sub-pixels of the second color in the last first pixel column; or, the sub-pixels of the first color in the first and third first pixel columns are connected to the data line corresponding to the second first pixel column via a first connecting line, and the data line of the sub-pixels of the first color in the last first pixel column is only connected to the sub-pixels of the first color in the last first pixel column;

[0023] Alternatively, in the last three first pixel columns within the display area, the first color sub-pixels in the last and third-to-last first pixel columns are connected to the corresponding data lines of the second-to-last first pixel column via a first connecting line, and the data lines of the first color sub-pixels in the first first pixel column are only connected to the first color sub-pixels in the first first pixel column; or, the second color sub-pixels in the last and third-to-last first pixel columns are connected to the corresponding data lines of the second-to-last first pixel column via a second connecting line, and the data lines of the second color sub-pixels in the first first pixel column are only connected to the first color sub-pixels in the first first pixel column.

[0024] In some embodiments, the aforementioned first connecting line is disposed on the same layer as the data line or scan line, and the second connecting line is disposed on the same layer as the data line or scan line, and has the same extension direction as the scan line.

[0025] Secondly, this application provides a driving method for a display panel, used to drive the display panel in any of the embodiments mentioned in the first aspect above. The specific driving method is as follows: during the scanning of each pixel row, pixel driving data is sequentially output to the sub-pixels connected to it via data lines, and the sub-pixels connected to the same data line have the same color.

[0026] In some embodiments, if a data line is connected to two sub-pixels in the same pixel row, during the scanning of that pixel row, pixel driving data of one of the sub-pixels is output through the data line, or a pixel driving weighted data is output through the data line, which is obtained by weighting the pixel driving data of the two sub-pixels.

[0027] In some embodiments, the method for obtaining pixel-driven weighted data by weighting the pixel-driving data of two sub-pixels is as follows: DataOUT = a*Data1 + b*Data2, where Data1 refers to the pixel-driving data of the first sub-pixel of the two sub-pixels, Data2 refers to the pixel-driving data of the second sub-pixel of the two sub-pixels, a and b are the weighting coefficients of the first and second sub-pixels respectively, and DataOUT is the final pixel-driving weighted data.

[0028] Thirdly, this application provides a display device including the display panel in any of the embodiments mentioned in the first aspect above.

[0029] The display panel, display panel driving method, and display device provided in this application embodiment, wherein for the case where the first pixel column includes at least two colors of sub-pixels spaced apart in the column direction, the sub-pixels of the same color in each first pixel column are connected to the same data line, and the sub-pixels of the same color in at least two first pixel columns share the same data line, thereby realizing separate driving of sub-pixels of different colors in the first pixel column, with each data line providing only one color driving voltage signal. Since the grayscale values ​​of sub-pixels of the same color are the same or very close, the voltage signal does not need to change or changes only slightly. Therefore, the driving voltage signal on the data line does not need to flip or only needs to flip by a small amplitude, greatly reducing power loss. Attached Figure Description

[0057] The technical solutions in some 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, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application are within the scope of protection of this application.

[0058] Unless the context otherwise requires, throughout the specification and claims, the term "comprising" is interpreted as open and encompassing, that is, "including, but not limited to".

[0059] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this application, unless otherwise stated, "a plurality of" means two or more.

[0060] In describing some embodiments, the term "connection" and its derivative expressions may be used. The term "connection" should be interpreted broadly; for example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. For example, in describing some embodiments, the term "connection" may be used to indicate that two or more components have direct physical or electrical contact with each other.

[0061] In addition, the use of “based on” implies openness and inclusivity, because processes, steps, calculations or other actions “based on” one or more of the stated conditions or values ​​may in practice be based on additional conditions or values ​​beyond those stated.

[0062] It should be understood that when a layer or element is referred to as being on another layer or substrate, it may mean that the layer or element is directly on the other layer or substrate, or that there is an intermediate layer between the layer or element and the other layer or substrate. Exemplary embodiments are described herein with reference to cross-sectional views as idealized exemplary drawings. In the drawings, for clarity, the thickness of the layers and the area of ​​the regions are enlarged. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Therefore, exemplary embodiments should not be construed as being limited to the shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing. Thus, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the regions of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0063] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0064] In related technologies, a single data line may connect sub-pixels of multiple colors. Figure 1 is a schematic diagram of the structure of a display panel in related technologies. As shown in Figure 1, the display area (AA area) of the display panel is provided with multiple columns of sub-pixels, and each column of sub-pixels is provided with a corresponding data line. Some columns of sub-pixels include sub-pixels of different colors. In Figure 1, rectangles with different fill sizes are used to represent different colors. In the working state, the pixel driving data, i.e., voltage signals, required by sub-pixels of different colors may have large deviations. For example, when displaying a red image, the grayscale value of the red sub-pixel is 255, and the required voltage signal may be 3V, while the grayscale value of the blue sub-pixel is 0, and the required voltage signal may be 7V. During the interval between each sub-pixel being selected by the scan line, the voltage signal on the data line needs to be constantly flipped to meet different requirements, which will cause a large power loss.

[0065] In response to the above situation, this application provides a corresponding solution. Specifically, each data line on the display panel is connected to only one fixed color sub-pixel, and each data line provides only one color sub-pixel voltage signal. When displaying a solid color image or an image with mostly solid colors as the background, the voltage signals required for each color sub-pixel are the same or very close. The voltage signals on each data line do not need to be flipped or only need to be flipped by a small amount, thereby greatly reducing power loss.

[0066] Specifically, Figure 2 is a schematic diagram of the structure of a display panel provided in an embodiment of this application. As shown in Figure 2, this application provides a display panel in which a first pixel column, multiple data lines DL and multiple scan lines GL (not shown in the figure) are provided in the display area (AA area) of the display panel. The first pixel column includes at least two colors of sub-pixels that are spaced apart in the column direction.

[0067] The aforementioned scan lines, data lines, and sub-pixels can be formed sequentially on a substrate, with the sub-pixels arranged in multiple rows and columns. Each sub-pixel includes a pixel electrode and a thin-film transistor (TFT). The gate of the TFT is connected to the scan line for sub-pixel selection, the source of the TFT is connected to the data line for receiving pixel driving data, and the drain of the TFT is connected to the pixel electrode for ultimately controlling the grayscale value of the sub-pixel. In other words, the sub-pixel is connected to the data line through the source of its TFT.

[0068] As shown in Figure 2, the sub-pixels on the display panel can be arranged into a multi-row, multi-column pixel matrix according to the extension direction of the data lines and scan lines. The first pixel column can correspond to the pixel columns 1, 3, and 5 in Figure 2. As shown in Figure 2, the first pixel column includes sub-pixels of two colors, namely sub-pixels of the first color A and sub-pixels of the second color B. In some cases, it can also include sub-pixels of three colors. In this embodiment, it is described with sub-pixels of two colors.

[0069] In this embodiment of the application, sub-pixels of the same color in each first pixel column are connected to the same data line, and at least two sub-pixels of the same color in the first pixel column reuse the same data line, as shown in Figure 2. For example, sub-pixel A in the first first pixel column (corresponding to the first column of the pixel matrix) and sub-pixel A in the second first pixel column (corresponding to the third column of the pixel matrix) reuse the same data line.

[0070] As described above, when a column of the pixel matrix includes two different colors of sub-pixels, the sub-pixels of different colors in that column are driven separately by connecting the sub-pixels of the same color to the same data line. Each data line provides a voltage signal for only one color of sub-pixel. When the grayscale values ​​of sub-pixels of the same color are the same or close, the required voltage signals are also the same or close. Therefore, during the scanning gap of the scan line, the voltage signals on the data line do not need to flip or only need to flip by a small amplitude, which greatly reduces power loss. In addition, by multiplexing the same data line for sub-pixels of the same color in different columns of the pixel matrix, the surge in the number of data lines can be effectively avoided, thereby avoiding increasing the area of ​​the routing area.

[0071] In some embodiments, as shown in FIG2, the display panel further includes a second pixel column, which corresponds to the second, fourth, and sixth columns in the pixel matrix. The first pixel column and the second pixel column are spaced apart in the row direction, and the second pixel column includes sub-pixels of the same color. The sub-pixels of the same color can be a third color that is different from the first and second colors in the first pixel column, so as to form the three primary colors required for display.

[0072] In some embodiments, at least some sub-pixels of the same color in two adjacent first pixel columns may share the same data line. As shown in Figure 2, sub-pixel A in the first first pixel column (corresponding to the first column of the pixel matrix) shares the same data line with sub-pixel A in the second first pixel column (corresponding to the third column of the pixel matrix), sub-pixel B in the second first pixel column (corresponding to the third column of the pixel matrix) shares the same data line with sub-pixel B in the third first pixel column (corresponding to the fifth column of the pixel matrix), and so on. This method of sharing the same data line between two adjacent first pixel columns is mainly to take into account that there is a second pixel column between two adjacent first pixel columns. When sharing the data line, there will be a problem that the connecting line crosses the data line of the second pixel column. If the sub-pixels sharing the same data line are far apart in the arrangement, it will lead to the connecting line being too long, crossing multiple data lines in the middle, and there may be a situation where a certain data line provides pixel driving data for more than one sub-pixel in a certain row at the same time. The technical solution provided in this embodiment can avoid the above problems as much as possible.

[0073] In some embodiments, the arrangement of sub-pixels of different colors is such that, in the odd-numbered first pixel columns, the sub-pixels of the first color and the second color are alternately arranged, and in the even-numbered first pixel columns, the sub-pixels of the second color and the first color are alternately arranged; the second pixel columns are all sub-pixels of the third color. Specifically, it can be shown in Figure 2. The first color, the second color, and the third color can be any one of red, green, and blue. As shown in Figure 2, the first color is red, the second color is blue, and the third color is green. Those skilled in the art will understand that the specific colors of the first color, the second color, and the third color can be set according to specific needs. The embodiments of this application are only given as an example and are not intended to limit. Thus, according to the principle that at least some sub-pixels of the same color reuse the same data line, the type of data line can be divided into three categories: the sub-pixels of the first color correspond to the first data line, the sub-pixels of the second color correspond to the second data line, and the sub-pixels of the third color correspond to the third data line.

[0074] In Figures 3-14 and 16-21 of the subsequent embodiments of this application, the technical solution will be described using the arrangement of sub-pixels in a certain manner as an example. This method treats 2*4 sub-pixels as a basic unit, and the pixels within the display area are copied and expanded based on this basic unit in the extension directions of the data lines and scan lines to form the pixel matrix of the final display area.

[0075] A basic unit consists of 2 rows and 4 columns of subpixels. The first row is arranged in the color sequence "red-green-blue-green," and the second row is arranged in the color sequence "blue-green-red-green." In the odd-numbered columns of this basic unit, red and blue are arranged alternately. In the pixel matrix expanded from this basic unit, any 2*2 subpixel region contains subpixels of all three colors, and the grayscale values ​​of the different colored subpixels are not exactly the same. They are combined to form the desired display image. Within this basic unit, each row contains one subpixel of the first color, one subpixel of the second color, and two subpixels of the third color. Odd-numbered columns contain one subpixel of the first color and one subpixel of the second color, and even-numbered columns contain two subpixels of the third color.

[0076] As shown in Figures 3 to 8, the specific connection method for at least some sub-pixels of the same color in two adjacent first pixel columns to reuse the same data line can include two cases:

[0077] The first case is: the first color sub-pixel in the 2mth first pixel column is connected to the data line of the first color sub-pixel in the 2m-1th first pixel column through the first connecting line X1, and the second color sub-pixel in the 2m+1th first pixel column is connected to the data line of the second color sub-pixel in the 2mth first pixel column through the second connecting line X2, as shown in Figures 3 to 5;

[0078] Where m is a positive integer. When the pixel matrix is ​​expanded from a basic unit, m refers to the number of basic units in the row direction. According to the above description of the arrangement, each basic unit has 2 first pixel columns and 2 second pixel columns. Therefore, the pixel matrix has 2m first pixel columns and 2m second pixel columns.

[0079] The 2m-1th first pixel column corresponds to the first first pixel column in the m-th basic unit of the entire pixel matrix, which is also the 4n-3th column of the pixel matrix, where n is the same positive integer as m; similarly, the 2mth first pixel column corresponds to the second first pixel column in the m-th basic unit of the entire pixel matrix, which is also the 4n-1th column of the pixel matrix; the 2m+1th first pixel column corresponds to the first first pixel column in the (m+1)-th basic unit of the entire pixel matrix, which is also the 4n+1th column of the pixel matrix.

[0080] The second case is: the second color sub-pixel in the 2m-1th first pixel column is connected to the data line of the second color sub-pixel in the 2mth first pixel column through the second connection line X2, and the first color sub-pixel in the 2mth first pixel column is connected to the data line of the first color sub-pixel in the 2m+1th first pixel column through the first connection line X1, as shown in Figures 6 to 8;

[0081] Similar to the previous case, m is a positive integer. The pixel matrix is ​​expanded from a basic unit, and m refers to the number of basic units in the row direction. Therefore, the 2m-1th first pixel column corresponds to the first first pixel column in the mth basic unit of the entire pixel matrix, which is also the 4n-3th column of the pixel matrix. Here, n is the same positive integer as m. Similarly, the 2mth first pixel column corresponds to the second first pixel column in the mth basic unit of the entire pixel matrix, which is also the 4n-1th column of the pixel matrix; the 2m+1th first pixel column corresponds to the first first pixel column in the (m+1)th basic unit of the entire pixel matrix, which is also the 4n+1th column of the pixel matrix.

[0082] In both of the above cases, the first connecting line X1 and the second connecting line X2 extend along the direction of the pixel row.

[0083] As shown in Figures 3 to 8, in the implementation of this application, apart from the first and last first pixel columns, the data lines of each intermediate first pixel column are reused, which effectively avoids the increase in the number of data lines and effectively controls the routing area required for the data lines.

[0084] In some embodiments, as shown in FIG3, the second color sub-pixel in the first first pixel column of the display area is provided with a separate data line, and the data line is only connected to the second color sub-pixel in the first first pixel column, that is, the data line is only connected to the sub-pixel in the even-numbered row of the first column of the pixel matrix, as shown in FIG3 as the data line marked L(0); the second color sub-pixel in the last first pixel column is provided with a separate data line, and the data line is only connected to the second color sub-pixel in the last first pixel column, that is, the data line is only connected to the sub-pixel in the odd-numbered row of the second-to-last column of the pixel matrix, that is, the 4n-1th column, as shown in FIG3 as the data line marked L(4n-1); at this time, the number of data lines is one more than the number of columns of the pixel matrix, and correspondingly, the output channel of the source driver is also increased by one. The extra data line and its corresponding output channel are marked as L(0) and used to output the voltage signal of the second color sub-pixel, that is, the blue sub-pixel. The remaining data lines and their corresponding output channels output the corresponding pixel driving data in the order of "red-green-blue-green".

[0085] Accordingly, the correspondence between the pixel driving data output on the data lines arranged in the above order and the pixel matrix during line-by-line scanning can be shown in Table 1 below.

[0086] Table 1

[0087] In Table 1 above, L(0)~L(4n) represent the data lines and their corresponding output channels in the figure. C1 represents the sub-pixel of the first color, which is red in this case. C2 represents the sub-pixel of the second color, which is blue in this case. C3 represents the sub-pixel of the third color, which is green in this case. C2-0 represents the sub-pixel of the second color connected to the data line set separately in the first pixel column. C1-n represents the nth sub-pixel of the first color in this row. C2-n represents the nth sub-pixel of the second color in this row. C3-(2n-1) represents the (2n-1)th sub-pixel of the third color in this row. C3-2n represents the (2n)th sub-pixel of the third color in this row. And so on. Additionally, the data lines C1(1,1), C2(1,1), C3(1,1)...C1(2i,n) represent the output signals corresponding to the sub-pixels of each color. (1,1), (2,1), (2i,1)...(2i,n) are the coordinates of each sub-pixel in the pixel matrix. For example, the output signal on the data line for the third color sub-pixel in the L(4n) column and 2i row of the table is C3(2i,2n). This means that when the sub-pixel in the 2i row of the pixel matrix is ​​selected by the scan line, the data line marked L(4n) and its corresponding output channel should provide the voltage signal required by the 2nth third color sub-pixel in the 2i row of the pixel matrix, and so on. Here, n is equivalent to the nth basic unit expanded in the row direction when the pixel matrix of the display area is expanded according to the above basic units, and i represents the ith basic unit expanded in the column direction. Both i and n are positive integers. Except for Table 1, all fields in Tables 2-12 in the following embodiments of this application have the same meaning as described above, and will not be repeated hereafter.

[0088] In some other embodiments as shown in Figure 4, the second-color sub-pixels in the first first pixel column of the display area are provided with separate data lines. These data lines are only connected to the second-color sub-pixels in the first first pixel column, meaning they are only connected to the sub-pixels in the even-numbered rows of the first column in the pixel matrix, as shown by the data line marked L(1) in Figure 4. Similarly, the second-color sub-pixels in the last first pixel column are provided with separate data lines. These data lines are only connected to the second-color sub-pixels in the last first pixel column, meaning they are only connected to the sub-pixels in the odd-numbered rows of the second-to-last column of the pixel matrix, which is the (4n-1)th column. Subpixel connections are shown as data lines marked L(0) in Figure 4. At this time, the number of data lines is one more than the number of columns in the pixel matrix. Correspondingly, the output channel of the source driver is also increased by one. The extra data line and its corresponding output channel are marked as L(0) and used to output the voltage signal of the second color subpixel, that is, the blue subpixel. The remaining data lines output the corresponding pixel driving data in the order of "blue-green-red-green". At this time, the correspondence between the pixel driving data output on the data lines and the pixel matrix can be shown in Table 2 below. The meaning of each field in Table 2 can be referred to the description in the embodiment shown in Table 1.

[0089] Table 2

[0090] Alternatively, as in the second case described above, as shown in Figure 6, a separate data line is set for the first color sub-pixel in the first first pixel column of the display area. This data line is only connected to the first color sub-pixel in the first first pixel column, as shown by the data line marked L(0) in Figure 6. A separate data line is set for the first color sub-pixel in the last first pixel column. This data line is only connected to the first color sub-pixel in the last first pixel column. That is, this data line is only connected to the sub-pixel in the even-numbered row of the second-to-last column of the pixel matrix, which is the 4n-1th column of the pixel matrix, as shown by the data line marked L(4n-1) in Figure 6. In this case, the number of data lines is one more than the number of columns in the pixel matrix. Correspondingly, the output channel of the source driver is also increased by one. The extra data line and its corresponding output channel are marked as L(0) and used to output the voltage signal of the first color sub-pixel, that is, the red sub-pixel. The remaining data lines output the corresponding pixel driving data in the order of "blue-green-red-green".

[0091] Accordingly, when the data lines are scanned line by line according to the above order, the correspondence between the pixel driving data output on the data lines and the pixel matrix can be shown in Table 3 below. The meaning of each field in Table 3 can be referred to the description in the embodiment shown in Table 1.

[0092] Table 3

[0093] In some other embodiments shown in Figure 7, the first color sub-pixel in the first first pixel column of the display area is provided with a separate data line. This separate data line is only connected to the first color sub-pixel in the first first pixel column, as shown by the data line marked L(1) in Figure 7, which is used to output the voltage signal of the red sub-pixel. The data line outputs the corresponding pixel driving data in the order of "red-green-blue-green". The first color sub-pixel in the last first pixel column is provided with a separate data line. This data line is only connected to the first color sub-pixel in the last first pixel column. That is, this data line is only connected to the sub-pixel in the even-numbered row of the second to last column of the pixel matrix, which is the 4n-1th column of the pixel matrix, as shown by the data line marked L(0) in Figure 7. The correspondence between the pixel driving data output on the data line and the pixel matrix can be shown in Table 4 below. The meaning of each field in Table 4 can be referred to the description in the embodiment shown in Table 1.

[0094] Table 4

[0095] In some embodiments, in order to maintain the regular arrangement of data lines, the first connection line X1 connecting the first color sub-pixel in the last first pixel column of the display area to its data line needs to cross the data line of the adjacent second pixel column, as shown in Figure 4 or Figure 7; or, the relative positional relationship between the data line of the first color sub-pixel in the last first pixel column and the data line of the adjacent second pixel column is locally adjusted so that the first connection line X1 connecting the first color sub-pixel in the last first pixel column to its data line does not cross the data line of the adjacent second pixel column, as shown in Figure 5 or Figure 8.

[0096] Furthermore, in the embodiments shown in Figures 3 to 8 of this application, the number of data lines is one more than the number of pixel columns in the pixel matrix, and an additional output channel is required from the source driver. In the embodiments of this application, in order to reduce the number of data lines and output channel data, the number of data lines and output channels is reduced to be the same as the number of pixel columns in the pixel matrix. In some embodiments, the second data line corresponding to the second color sub-pixel of the first first pixel column in the display area and the second data line corresponding to the second color sub-pixel of the last first pixel column in the display area can be connected by a third connecting line X3 and / or a fourth connecting line X4, as shown in Figures 9 to 11.

[0097] As shown in some embodiments of Figure 9, the data lines output the corresponding pixel driving data sequentially in the order of "red-green-blue-green". Since the sub-pixels of the second color in the first first pixel column and the sub-pixels of the second color in the last first pixel column are connected together by the third connecting line X3 and / or the fourth connecting line X4, the voltage signal output in the odd-numbered rows of the data lines corresponding to the last first pixel column, i.e., the data lines labeled L(4n-1), is the voltage signal required by the sub-pixels in the corresponding odd-numbered rows of the last first pixel column in the pixel matrix, and the voltage signal output in the even-numbered rows is the voltage signal required by the sub-pixels in the corresponding even-numbered rows of the first first pixel column in the pixel matrix. The correspondence between the pixel driving data output on the data lines and the pixel matrix can be shown in Table 5 below. The meaning of each field in Table 5 can be referred to the description in the embodiments shown in Table 1.

[0098] Table 5

[0099] In some embodiments shown in Figures 10 and 11, the data lines output the corresponding pixel driving data sequentially in the order of "blue-green-red-green". Since the sub-pixels of the second color in the first first pixel column and the sub-pixels of the second color in the last first pixel column are connected together by the third connecting line X3 and / or the fourth connecting line X4, the voltage signal output in the odd-numbered row of the data line corresponding to the first first pixel column, i.e., the data line labeled L(1), is the voltage signal required by the sub-pixels in the corresponding odd-numbered row of the last first pixel column (i.e., the 4n-1th column of the pixel matrix), and the voltage signal output in the even-numbered row is the voltage signal required by the sub-pixels in the corresponding even-numbered row of the first first pixel column in the pixel matrix. The correspondence between the pixel driving data output on the data lines and the pixel matrix can be shown in Table 6 below. The meaning of each field in Table 6 can be referred to the description in the embodiment shown in Table 1.

[0100] Table 6

[0101] Alternatively, the first data line corresponding to the first color sub-pixel in the last first pixel column of the display area and the first data line corresponding to the first color sub-pixel in the first first pixel column of the display area are connected by a third connecting line X3 and / or a fourth connecting line X4, as shown in Figures 12 to 14.

[0102] As shown in some embodiments of Figure 12, the data lines output the corresponding pixel driving data sequentially in the order of "blue-green-red-green". Since the first color sub-pixel in the first first pixel column and the first color sub-pixel in the last first pixel column are connected together through the third connecting line X3 and / or the fourth connecting line X4, the voltage signal output in the odd-numbered row of the data line corresponding to the last first pixel column, i.e., the data line labeled L(4n-1), is the voltage signal required by the sub-pixel in the corresponding odd-numbered row of the first first pixel column in the pixel matrix, and the voltage signal output in the even-numbered row is the voltage signal required by the sub-pixel in the corresponding even-numbered row of the last first pixel column in the pixel matrix. The correspondence between the pixel driving data output on the data lines and the pixel matrix can be shown in Table 7 below. The meaning of each field in Table 7 can be referred to the description in the embodiment shown in Table 1.

[0103] Table 7

[0104] In some embodiments shown in Figures 13 and 14, the data lines output the corresponding pixel driving data sequentially in the order of "red-green-blue-green". Since the first color sub-pixel in the first first pixel column and the first color sub-pixel in the last first pixel column are connected together through the third connecting line X3 and / or the fourth connecting line X4, the voltage signal output in the odd-numbered row of the data line corresponding to the first first pixel column, i.e., the data line labeled L(1), is the voltage signal required by the sub-pixel in the corresponding odd-numbered row of the first first pixel column in the pixel matrix, and the voltage signal output in the even-numbered row is the voltage signal required by the sub-pixel in the corresponding even-numbered row of the last first pixel column in the pixel matrix. The correspondence between the pixel driving data output on the data line and the pixel matrix can be shown in Table 8 below. The meaning of each field in Table 8 can be referred to the description in the embodiment shown in Table 1.

[0105] Table 8

[0106] The aforementioned third connection line X3 and fourth connection line X4 extend along the direction of the pixel row, with the third connection line X3 located at the driving end of the display area and the fourth connection line X4 located at the end of the display area opposite to the driving end. Here, the driving end refers to the end closer to the aforementioned source driver, that is, the end that provides driving data to the data line; while the end refers to the end farther away from the source driver.

[0107] Figure 15 illustrates a third / fourth connection line configuration method provided in an embodiment of this application. This figure is only used as an example of connecting data lines numbered L(4n-1) and L(0) together. The relevant data line numbers are not specifically referred to. In other embodiments, the corresponding numbers can be replaced according to the specific situation. Taking the third connecting line X3 as an example, as shown in Figure 15, L(SC) represents the scan line layer. In order to connect the data line L(4n-1) and the data line L(0) together, the third connecting line X3 needs to cross multiple data lines in the middle. Therefore, the third connecting line X3 can be set on the same layer as the scan line. In the figure, L(VIA) represents the connecting line via, which is used for connecting line routing. One end of the third connecting line X3 is connected to the data line L(0), and then through the connecting line via L(VIA) to the scan line layer L(SC). After that, it is connected to the data line L(4n-1) through another connecting line via L(VIA). This means that the third connecting line X3 is set on the same layer as the scan line. This setting method will avoid the situation where the third connecting line X3 keeps bending when crossing multiple data lines. At the end of the display area, data lines and scan lines are usually not set. Therefore, the fourth connecting line X4 can be set on the same layer as the data line or scan line.

[0108] In some other embodiments, in order not to increase the number of data lines or expand the area occupied by the data lines, the sub-pixels of the same color in the first three first pixel columns can be connected to the same data line through connecting lines. For example, in the first case, the sub-pixels of the second color in the first and third first pixel columns in the display area can be connected to the data line corresponding to the second first pixel column through the second connecting line X2. The data line of the sub-pixels of the second color in the last first pixel column is only connected to the sub-pixels of the second color in the last first pixel column, as shown in Figure 16. At this time, when the even-numbered row of the pixel matrix is ​​scanned and selected, the pixel driving data output by the data line labeled L(3) and its corresponding output channel simultaneously provides voltage signals for the first and second second-color sub-pixels of the corresponding row. For example, for the second-color sub-pixels in column L(3) and row 2i in the table, the output signals on the data line are C2(2i,1) and C2(2i,2), which means that when the sub-pixels in row 2i of the pixel matrix are scanned and selected, the data line labeled L(3) and its corresponding output channel should provide the voltage signals required by the first and second second-color sub-pixels in row 2i of the pixel matrix. Correspondingly, the data line labeled L(4n-5) and its corresponding output channel should provide the voltage signal required by the nth second-color sub-pixel in row 2i of the pixel matrix. The data line labeled L(4n-1) and its corresponding output channel can not output at this time, and so on. The correspondence between the pixel-driven data output on the data line and the pixel matrix can be found in Table 9 below. The meaning of each field in Table 9 can be found in the embodiment shown in Table 1.

[0109] Table 9

[0110] Alternatively, the first color subpixels in the first and third first pixel columns are connected to the data line corresponding to the second first pixel column via the first connecting line X1, and the data line of the first color subpixel in the last first pixel column is only connected to the second color subpixel of the last first pixel column, as shown in Figure 17. At this time, when the odd-numbered row of the pixel matrix is ​​scanned and selected, the pixel driving data output by the data line labeled L(3) and its corresponding output channel simultaneously provides voltage signals for the first and second first-color sub-pixels of the corresponding row. For example, for the first-color sub-pixels in column L(3) and row 2i-1 of the table, the output signals on the data line are C1(2i-1,1) and C1(2i-1,2), which means that when the sub-pixels in row 2i-1 of the pixel matrix are scanned and selected, the data line labeled L(3) and its corresponding output channel should provide the voltage signals required by the first and second first-color sub-pixels in row 2i-1 of the pixel matrix. Correspondingly, the data line labeled L(4n-5) and its corresponding output channel should provide the voltage signal required by the nth first-color sub-pixel in row 2i-1 of the pixel matrix. The data line labeled L(4n-1) and its corresponding output channel can not output at this time, and so on. The correspondence between the pixel driving data output on the data line and the pixel matrix can be found in Table 10 below. The meaning of each field in Table 10 can be found in the embodiment shown in Table 1.

[0111] Table 10

[0112] Alternatively, corresponding to the first case mentioned above, the sub-pixels of the same color in the last three first pixel columns can be connected to the same data line through connecting lines. For example, in the second case, the first color sub-pixels of the last and third-to-last first pixel columns in the last three first pixel columns in the display area can be connected to the data line corresponding to the second-to-last first pixel column through the first connecting line X1. The data line of the first color sub-pixel in the first first pixel column is only connected to the first color sub-pixel of the first first pixel column, as shown in Figure 18. At this time, when the even-numbered row of the pixel matrix is ​​scanned and selected, the pixel driving data output by the data line labeled L(4n-3) and its corresponding output channel simultaneously provides voltage signals for the nth and (n-1th)th first-color sub-pixels of the corresponding row. For example, the first-color sub-pixels in the L(4n-3)th column and the 2ith row of the table have output signals C1(2i,n-1) and C1(2i,n) on the data line. This means that when the sub-pixels in the 2ith row of the pixel matrix are scanned and selected, the data line labeled L(4n-3) and its corresponding output channel should provide the voltage signals required by the (n-1th)th and nth first-color sub-pixels in the 2ith row of the pixel matrix. Correspondingly, the data line labeled L(5) and its corresponding output channel should provide the voltage signal required by the first first-color sub-pixel in the 2ith row of the pixel matrix. The data line labeled L(1) and its corresponding output channel can not output at this time, and so on. The correspondence between the pixel-driven data output on the data line and the pixel matrix can be found in Table 11 below. The meaning of each field in Table 11 can be found in the embodiment shown in Table 1.

[0113] Table 11

[0114] Alternatively, in the last three first pixel columns within the display area, the second color subpixels of the last and third-to-last first pixel columns are connected to the data lines corresponding to the second-to-last first pixel column via the second connecting line X2. The data lines of the first color subpixels in the first first pixel column are only connected to the first color subpixels of the first first pixel column, as shown in Figure 19. At this time, when the odd-numbered row of the pixel matrix is ​​scanned and selected, the pixel driving data output by the data line labeled L(4n-3) and its corresponding output channel simultaneously provides voltage signals for the nth and (n-1th)th second-color sub-pixels in the corresponding row. For example, the output signals on the data lines of the second-color sub-pixels in the L(4n-3) column and the 2i-1th row of the table are C2(2i-1,n-1) and C2(2i-1,n). This means that when the sub-pixels in the 2i-1th row of the pixel matrix are scanned and selected, the data line labeled L(4n-3) and its corresponding output channel should provide the voltage signals required by the (n-1th)th and nth second-color sub-pixels in the 2i-1th row of the pixel matrix. Correspondingly, the data line labeled L(5) and its corresponding output channel should provide the voltage signal required by the first second-color sub-pixel in the 2i-1th row of the pixel matrix. The data line labeled L(1) and its corresponding output channel can not output at this time, and so on. The correspondence between the pixel-driven data output on the data line and the pixel matrix can be found in Table 12 below. The meaning of each field in Table 12 can be found in the embodiment shown in Table 1.

[0115] Table 12

[0116] In addition, in some embodiments, in the pixel matrix expanded from the basic unit, sub-pixels of the same color in the (4n-3)th and (4n-1)th columns share the same data line, as shown in Figures 20 and 21. For example, sub-pixels of the first color in the first column and sub-pixels of the first color in the third column of the pixel matrix share the same data line, and sub-pixels of the second color in the first column and sub-pixels of the second color in the third column share the same data line. The correspondence between the pixel driving data output on the data line and the pixel matrix can be found in Table 13 below. The meaning of each field in Table 13 can be found in the description in the embodiment shown in Table 1.

[0117] Table 13

[0118] In all the foregoing embodiments of the present application, the first connection line X1 can connect the sub-pixels of the first color to the first data line multiplexed by them. It can be arranged in the same layer as the data line or the scan line. The second connection line X2 can connect the sub-pixels of the second color to the second data line multiplexed by them. It can be arranged in the same layer as the data line or the scan line, and has the same extension direction as the scan line. As shown in FIGS. 22 to 23, in the figures, L(SC) represents the scan line layer, L(VIA) represents the connection line via, L(1) represents the data line multiplexed by the sub-pixels of the first color, L(2) represents the data line multiplexed by the sub-pixels of the second color, L(3) represents the data line multiplexed by the sub-pixels of the third color, A represents the sub-pixels of the first color, and B represents the sub-pixels of the second color.

[0119] Here, the first connection line X1 is taken as an example for illustration: In order to connect the sub-pixels A of the first color and the first data line L(1) of the adjacent first pixel column together to achieve the multiplexing of the same data line by two adjacent first pixel columns, the first connection line X1 needs to cross the third data line L(3) corresponding to the sub-pixels of the third color in the middle second pixel column. The first connection line X1 can be arranged in the same layer as the data line. As shown in FIG. 22, when the first connection line X1 is near the third data line L(3), it is locally folded to the scan line layer through the connection line via L(VIA); or as shown in FIG. 23, the first connection line X1 directly passes through the connection line via L(VIA) to the scan line layer L(SC), is arranged in the same layer as the scan line, and then is connected to the first data line L(1) through the connection line via L(VIA). The second connection line X2 is the same, and will not be elaborated here.

[0120] In a second aspect, the present application provides a driving method for a display panel. FIG. 24 is a schematic flow chart of the driving method for the display panel in an embodiment of the present application. As shown in FIG. 24, the driving method in the embodiment of the present application can be used to drive the display panel in any of the embodiments mentioned in the first aspect above. The specific driving method includes the following steps:

[0121] Step 101, during the scanning of each pixel row, output pixel data to the sub-pixels connected to it through the data line, and the colors of the sub-pixels connected to the same data line are the same.

[0122] As described in the embodiments of the display panel shown in Figures 2 to 14 above, the display panel, for cases where the first pixel column includes at least two colors of sub-pixels, achieves the transmission of voltage signals required by each data line by multiplexing at least some of the sub-pixels of the same color in two adjacent first pixel columns using the same data line. Under this driving method, when displaying a solid color image or an image with mostly solid colors, the voltage signal does not need to change or changes only slightly when the color levels of the sub-pixels of the same color are the same or close. Therefore, the driving voltage signal on the data line does not need to be switched or only needs to be switched slightly, which greatly reduces power loss.

[0123] In the embodiments shown in Figures 3 to 8, the sub-pixels within the display area are treated as a 2i x 4n pixel matrix. Based on the data line multiplexing method, 4n+1 data lines are divided. Then, the source driver provides 4n+1 output channels, each corresponding to one data line. Each data line transmits only the voltage signal required by a sub-pixel of a specific color. For the various data line layouts in the embodiments shown in Figures 3 to 8, the specific execution of step 101 can refer to the schemes in the embodiments shown in Tables 1 to 4. Corresponding pixel driving data is output through the data lines matching each pixel column on the display panel. As described in the above embodiments, the pixel driving data here refers to the voltage signal required by the corresponding sub-pixel. In the embodiments shown in Figures 9 to 14, the sub-pixels within the display area are treated as a 2i x 4n pixel matrix. Based on the data line multiplexing method, 4n data lines are divided. Then, the source driver provides 4n output channels, each corresponding to one data line. Each data line transmits only the voltage signal required by a sub-pixel of a specific color. For the various data line layouts in the embodiments shown in Figures 9 to 14, the specific execution of step 101 can refer to the schemes in the embodiments shown in Tables 5 to 8 above. The corresponding pixel driving data is output through the data lines on the display panel that match each pixel column. As described in the above embodiments, the pixel driving data here refers to the voltage signal required by the corresponding sub-pixel.

[0124] In the embodiments shown in Figures 16 to 19 above, to avoid the number of data lines exceeding the number of pixel columns and to avoid connecting lines spanning long distances, the data lines in this embodiment can be connected to two sub-pixels in the same pixel row. In this case, during the scanning of the pixel row, pixel driving data can be provided to the two sub-pixels through the data lines. The pixel driving data can be the pixel data of either of the two sub-pixels. Alternatively, in some other embodiments, a pixel weighted data can be output through the data lines. The pixel weighted data is obtained by weighting the pixel driving data of the two sub-pixels.

[0125] For example, as shown in Tables 9 to 12 above, taking Table 9 as an example, the output signals on the data lines of the second color sub-pixels in column L(3) and row 2i are C2(2i,1) and C2(2i,2). This means that when the sub-pixels in row 2i of the pixel matrix are selected by the scan line, the data line marked L(3) and its corresponding output channel should provide the voltage signals required by the first and second second color sub-pixels in row 2i of the pixel matrix. At this time, when row 2i is selected by the scan line, the voltage signal output on the data line corresponding to L(3) can be C2(2i,1), which is the voltage signal required by the first second color sub-pixel in row 2i, or C2(2i,2), which is the voltage signal required by the second second color sub-pixel in row 2i, or the voltage signals required by the first and second second color sub-pixels are weighted and the weighted voltage signal is output.

[0126] Figure 25 is a schematic diagram of a pixel-driven data weighted calculation method provided in an embodiment of this application. Specifically, the pixel-weighted data calculation formula is: DataOUT = a*Data1 + b*Data2, where Data1 refers to the pixel data of the first sub-pixel of the two sub-pixels, and Data2 refers to the pixel data of the second sub-pixel of the two sub-pixels. a and b are weight coefficients, with values ​​ranging from 0 to 5. The value step can be set to 0.1, that is, the weight coefficient can be any value such as 2.3 or 2.4. The weight coefficient can be set in advance and stored in the driver data processing chip. When the data line provides pixel-driven data for two sub-pixels on the same row, the pixel data Data1 and Data2 of the above two sub-pixels can be input into the data processing chip, and data processing is performed according to the above calculation formula. Finally, DataOUT is output as the pixel-driven data of the two sub-pixels.

[0127] Thirdly, this application provides a display device. FIG26 is a schematic diagram of the structure of the display device in an embodiment of this application. As shown in FIG26, the display device 10 includes a display panel 20, which can be the display panel in any of the embodiments mentioned in the first aspect above. The display area of ​​the panel is provided with a first pixel column, multiple data lines, and multiple scan lines. The first pixel column includes at least two colors of sub-pixels distributed at intervals in the column direction. Sub-pixels of the same color in each first pixel column are connected to the same data line, and sub-pixels of the same color in at least two first pixel columns reuse the same data line. This display device has the technical features and effects described in the above embodiments, which will not be repeated in this embodiment. This display device is beneficial to reducing device power consumption and achieving energy-saving goals.

[0128] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
