[0061] The beneficial effects of this disclosure are as follows:

[0062] This disclosure addresses existing problems by providing a display panel and display device. By electrically connecting each data signal line to at least a portion of the sub-pixels of the same color arranged along its extension direction, a data signal line provides data signals only to sub-pixels of the same color. This avoids color deviation and cross-contamination caused by incorrect charging of different colors during charging, improves the display effect, and has broad application prospects. Detailed Implementation

[0063] To more clearly illustrate this disclosure, the preferred embodiments and accompanying drawings will be used for further description. Similar components in the drawings are indicated by the same reference numerals. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of this disclosure.

[0064] It should be noted that, unless otherwise defined, the technical or scientific terms used in this disclosure should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms "an," "a," or "the," etc., do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms "comprising," "including," etc., mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. The terms "connected," "linked," etc., are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0065] Reference Figure 1 As shown in the figure, in a typical example, the pixel arrangement in the display panel is as follows: if a row has 15 pixels, then the first row contains pixels 1-1 to 1-15 (pixels 1-1 to 1-15), and the second row contains pixels 2-1 to 2-15 (pixels 1-1 to 2-15). A pixel is composed of multiple sub-pixels, as shown in the figure. Figure 2 As shown, if a pixel is composed of three sub-pixels: red (R), green (G), and blue (B), then according to... Figure 1 The pixel arrangement in the image uses a method where each pixel corresponds to three sub-pixels, and these sub-pixels are arranged sequentially according to the pixel arrangement method. Of course, Figure 2 The purpose is to represent the correspondence between pixels and subpixels, and whether the subpixels in each pixel are arranged horizontally or vertically is not limited to this. Figure 2 As shown.

[0066] In related technologies, in display panels using a three-gate driving method, refer to Figure 3The example shown includes multiple data signal lines S1, S2, ..., S9, each providing a data signal to each sub-pixel in a column of pixels simultaneously. Taking data signal line S1 as an example, data signal line S1 is electrically connected to the red, green, and blue sub-pixels in the first pixel to provide data signals. This driving method reduces the number of channels required by the source driver chip for the display panel, thus reducing the number of source driver chips. Since the data on the data signal lines changes color depending on the driven sub-pixels, insufficient charging time can lead to color deviation and crosstalk problems caused by incorrect charging of different color data signals.

[0067] To address at least one of the above problems, this disclosure provides a display panel comprising: a plurality of pixel units arranged in an array, a plurality of scan signal lines, and a plurality of data signal lines.

[0068] Each pixel unit includes a plurality of sub-pixels, the plurality of sub-pixels including at least a first sub-pixel having a first color and a second sub-pixel having a second color, wherein the first color and the second color are different.

[0069] Each of the scan signal lines is electrically connected to at least a portion of the sub-pixels of different colors in each of the pixel units arranged along its extension direction.

[0070] Each of the data signal lines is electrically connected to a sub-pixel of the same color in at least a portion of the pixel units arranged along its extension direction.

[0071] In this embodiment, by setting each data signal line to be electrically connected to at least some of the sub-pixels of the same color in the pixel units arranged along its extension direction, a data signal line provides data signals only to sub-pixels of the same color, thereby avoiding color deviation and cross-coloring caused by incorrect charging of different colors during charging, and improving the display effect.

[0072] The embodiments of this disclosure will be described in detail below with specific examples and for specific structures.

[0073] In a specific example, refer to Figure 4 As shown, the display panel includes: multiple pixel units 10-1, multiple scan signal lines G1, G2, ..., G9 and multiple data signal lines S1, S2, ..., S9.

[0074] like Figure 4 As shown, the data signal lines extend along the first direction (i.e., the y direction) and are arranged along the second direction (i.e., the x direction), while the scan signal lines extend along the second direction and are arranged along the first direction. The first and second directions intersect.

[0075] In this example, for convenience, Figure 4Nine scan signal lines G1, G2, ..., G9 and nine data signal lines S1, S2, ..., S9 are shown. Those skilled in the art should understand that this is merely exemplary and not intended to be limiting.

[0076] Of course, this disclosure is not intended to limit the first direction to Figure 4 The y-direction in the middle, the second direction is Figure 4 In practical applications, the x-direction can be set as needed. However, for ease of description, this article will use the example of the first direction being the vertical (y-direction) and the second direction being the horizontal (x-direction).

[0077] It is understood that the display panel should also include a gate driving circuit and a source driving circuit. The gate driving circuit outputs a scan signal to the scan signal line through electrical connection with the scan signal line, and the source driving circuit outputs a data signal to the data signal line through electrical connection with the data signal line. Exemplarily, the source driving circuit can be specifically implemented as a source driving chip (e.g., a source IC), and the gate driving circuit can be, for example, a GOA circuit or a gate driving chip.

[0078] Optionally, each pixel unit includes multiple sub-pixels, and the multiple sub-pixels include at least a first sub-pixel with a first color and a second sub-pixel with a second color, wherein the first color and the second color are different.

[0079] In this specific example, each pixel unit 10-1 includes 3 sub-pixels, which are sub-pixels of 3 different colors: red (R), green (G), and blue (B). In other words, in this example, each pixel unit 10-1 is composed of three colors, with one sub-pixel of each color.

[0080] Of course, the embodiments disclosed herein are not limited to Figure 4 In the examples shown, in some instances, a pixel unit may also consist of only two colors of subpixels, one of each color.

[0081] It should be noted that when there is one sub-pixel of each color in each pixel unit, it means that each sub-pixel of each color in each pixel of the display panel carries only one image information, and therefore the display panel is a 2D display panel.

[0082] Continuing with this example, refer to Figure 4 As shown, the display panel also includes: a driving circuit corresponding to the pixel unit 10-1, each driving circuit including a driving unit 20-1 electrically connected to a sub-pixel, configured to write the data signal of the data signal line to the sub-pixel in response to the scanning signal of the scanning signal line.

[0083] In this example, refer to Figure 4 As shown, the driving unit 20-1 is a driving transistor. The first electrode of the driving transistor serves as the first terminal of the driving unit 20-1, the second electrode of the driving transistor serves as the second terminal of the driving unit 20-1, and the control electrode of the driving transistor serves as the third terminal of the driving unit 20-1. The driving transistor is configured to turn on in response to the scanning signal of the scanning signal line being at an effective level, thereby writing the data signal of the first electrode into the corresponding sub-pixel.

[0084] Optionally, each row of pixel units along the second direction corresponds to a set of scan signal lines. The number of scan signal lines in the set of scan signal lines is the period. The driving circuit of the row of pixel units is electrically connected to the scan signal lines in the set of scan signal lines in sequence. Along the first direction, the pixel units in the period of each pixel unit are called pixel unit groups and correspond to a set of data signal lines. Each data signal line in the set of data signal lines is electrically connected to the sub-pixel of the same color in the pixel unit group.

[0085] Specific reference Figure 4 The example diagram shows three sets of scan signal lines: one set consists of scan signal lines G1, G2, and G3; another set consists of scan signal lines G4, G5, and G6; and the third set consists of scan signal lines G7, G8, and G9. Taking the first row of pixel units along the x-direction as an example, this row corresponds to the first set of scan signal lines G1, G2, and G3, and includes nine pixel units 10⁻¹.

[0086] Specifically, the control electrode of each driving transistor in the first pixel unit 10-1 of the pixel unit row is electrically connected to the scan signal line G1; the control electrode of each driving transistor in the second pixel unit 10-1 is electrically connected to the scan signal line G2; the control electrode of each driving transistor in the third pixel unit 10-1 is electrically connected to the scan signal line G3; the control electrode of each driving transistor in the fourth pixel unit 10-1 is electrically connected to the scan signal line G1; the control electrode of each driving transistor in the fifth pixel unit 10-1 is electrically connected to the scan signal line G2; the control electrode of each driving transistor in the sixth pixel unit 10-1 is electrically connected to the scan signal line G3; the control electrode of each driving transistor in the seventh pixel unit 10-1 is electrically connected to the scan signal line G1; the control electrode of each driving transistor in the eighth pixel unit 10-1 is electrically connected to the scan signal line G2; and the control electrode of each driving transistor in the ninth pixel unit 10-1 is electrically connected to the scan signal line G3.

[0087] Along the extension direction of the data signal line, the pixel units in each cycle of a horizontal row of pixel units form a pixel unit group vertically with their corresponding pixel units. Specifically, refer to... Figure 4As shown, for each pixel unit row, a set of scan signal lines are connected sequentially with a period of 3. Vertically, every three pixel units form a pixel unit group, which in turn corresponds to a set of scan signal lines. For example, the pixel units in columns 1 to 3 correspond to a set of scan signal lines S1, S2, and S3. Each red sub-pixel R in this pixel unit group is electrically connected to data signal line S1, each green sub-pixel G is electrically connected to data signal line S2, and each blue sub-pixel B is electrically connected to data signal line S3. Of course, each sub-pixel is electrically connected to the corresponding data signal line through a corresponding driving transistor, which will not be elaborated here.

[0088] With the above settings, when the scan signal line G1 is connected to a valid scan signal, the driving transistors of the 1st, 4th, and 7th pixel units in the 1st pixel unit row are turned on, and the data signals on S1 to S9 corresponding to the data signals of each sub-pixel in that row are written to the corresponding sub-pixels. When the scan signal line G2 is connected to a valid scan signal, the driving transistors of the 2nd, 5th, and 8th pixel units in the 1st pixel unit row are turned on, and the data signals on S1 to S9 corresponding to the data signals of each sub-pixel in that row are written to the corresponding sub-pixels. When the scan signal line G3 is connected to a valid scan signal, the driving transistors of the 3rd, 6th, and 9th pixel units in the 1st pixel unit row are turned on, and the data signals on S1 to S9 corresponding to the data signals of each sub-pixel in that row are written to the corresponding sub-pixels. This achieves a multi-gate driving mode for display driving.

[0089] While performing the aforementioned multi-gate driving, each data signal line is connected to a sub-pixel of the same color, thus preventing color crosstalk. In other words, through the above settings, multi-gate driving is achieved to reduce the number of channels in the source driving circuit, thereby reducing the number of driver chips, while also eliminating color crosstalk issues.

[0090] In some alternative embodiments, multi-gate driving of 3D display panels that do not have color crosstalk issues is considered.

[0091] In a specific example, refer to Figure 5 As shown, the display panel includes: multiple pixel units 10-2, multiple scan signal lines G1, G2, ..., G6 and multiple data signal lines S1, S2, ..., S6.

[0092] and Figure 4Similarly, in the example shown, the data signal lines extend along a first direction (i.e., the y-direction) and are arranged along a second direction (i.e., the x-direction), and the scan signal lines extend along the second direction and are arranged along the first direction. The first and second directions intersect, but this embodiment is not intended to limit the first and second directions to the y-direction and x-direction shown in the figure.

[0093] In addition, also for convenience, Figure 5 Six scan signal lines G1, G2, ..., G6 and six data signal lines S1, S2, ..., S6 are shown, but this is merely illustrative and not intended to be limiting.

[0094] It is also understood that the display panel should include a gate driving circuit and a source driving circuit. Exemplarily, the source driving circuit can be specifically implemented as a source driving chip (e.g., a source IC), and the gate driving circuit can be, for example, a GOA circuit or a gate driving chip.

[0095] Optionally, each pixel unit 10-2 includes multiple sub-pixels, including a first sub-pixel, a second sub-pixel, and a third sub-pixel. The first sub-pixel is a first color, the second sub-pixel is a second color, and the third sub-pixel is a third color. The first color, the second color, and the third color are different. For example, the three color sub-pixels are red sub-pixel R, green sub-pixel G, and blue sub-pixel B, respectively.

[0096] To enable 3D display, pixel unit 10-2 includes three pixel islands arranged along a first direction, each pixel island including N sub-pixels of the same color arranged along a second direction, where N is an integer greater than or equal to 2. Specifically, in this example, N is 3. Of course, those skilled in the art will understand that this disclosure is not intended to limit the number of N; the larger the number of N, the richer the image information contained in the beam of light emitted by each color of a pixel unit during 3D display.

[0097] Of course. (Refer to...) Figure 5 As shown, the display panel also includes: a driving circuit corresponding to the pixel unit 10-2, each driving circuit including a driving unit 20-2 electrically connected to the sub-pixel in a one-to-one correspondence, configured to write the data signal of the data signal line into the sub-pixel in response to the scanning signal of the scanning signal line.

[0098] Specifically, in this example, the driving unit 20-2 is a driving transistor. The first terminal of the driving transistor serves as the first terminal of the driving unit 20-1, the second terminal serves as the second terminal of the driving unit 20-1, and the control terminal serves as the third terminal of the driving unit 20-1. The driving transistor is configured to turn on in response to a valid scan signal level on the scan signal line, thereby writing the data signal from the first terminal to the corresponding sub-pixel. However, this disclosure is not intended to limit the driving unit to this; other structures capable of implementing this function are also permitted.

[0099] Optionally, each pixel unit row along the second direction corresponds to N scan signal lines. Each pixel unit includes a sub-pixel group arranged in the first direction, consisting of a first sub-pixel, a second sub-pixel, and a third sub-pixel. The third end of the driving unit of the sub-pixel in the sub-pixel group is electrically connected to a scan signal line, the first end of the driving unit is electrically connected to a data signal line, and the second end is electrically connected to the sub-pixel. The data signal lines electrically connected to sub-pixels of the same color have the same polarity, and each data signal line is electrically connected to a sub-pixel of the same color in the pixel units arranged along its extension direction.

[0100] For a specific example, refer to Figure 5 and Figure 6 As shown, each row of pixel units along the x-direction corresponds to 3 scan signal lines. That is, the number of scan signal lines required for each row of pixel units is determined by the number of pixel islands contained in 10⁻² pixels per pixel unit. Figure 5 In the diagram, 1-1 represents the first pixel island in the first pixel unit row, 1-2 represents the second pixel island in the first pixel unit row, 1-3 represents the third pixel island in the first pixel unit row, and so on. The fourth, fifth, and sixth pixel islands correspond to the three pixel islands in the second pixel unit of the first pixel unit row.

[0101] Additionally, refer to Figure 5 As shown, each pixel unit 10-2 includes a sub-pixel group arranged in the y-direction, consisting of a first sub-pixel R, a second sub-pixel G, and a third sub-pixel B. Figure 5 Taking pixel unit 10-1, marked by the dashed box, as an example, it includes three sub-pixel groups. Each sub-pixel group includes a first sub-pixel R, a second sub-pixel G, and a third sub-pixel B corresponding in the y-direction. The control electrode of the driving transistor 20-2 of the sub-pixels in each sub-pixel group is electrically connected to the same scan signal line.

[0102] Different sub-pixel groups within a pixel unit 10-2 correspond to different scan signal lines among the three scan signal lines mentioned above. The first pole of sub-pixels of the same color within the same pixel unit 10-2 is electrically connected to the same data signal line. Each data signal line is electrically connected to sub-pixels of the same color in pixel units arranged along its extension direction.

[0103] Specific reference Figure 5 As shown, for Figure 5 Taking pixel unit 10-1, marked by the dashed box, the control electrode of the driving transistor 20-2 of the sub-pixel in the first sub-pixel group is electrically connected to the scan signal line G1; the control electrode of the driving transistor 20-2 of the sub-pixel in the second sub-pixel group is electrically connected to the scan signal line G2; and the control electrode of the driving transistor 20-2 of the sub-pixel in the third sub-pixel group is electrically connected to the scan signal line G3. The first electrode of the driving transistor 20-2 of the red sub-pixel is electrically connected to the scan signal line S1; the first electrode of the driving transistor 20-2 of the green sub-pixel is electrically connected to the scan signal line S2; and the first electrode of the driving transistor 20-2 of the blue sub-pixel is electrically connected to the scan signal line S3. Sub-pixels of the same color in corresponding pixel units along the y-direction are all electrically connected to the same data signal line.

[0104] This setup utilizes time-division scanning of the scan signal lines, allowing sub-pixels connected to the same data signal line to receive their own different data signals, thus achieving multi-gate driving. Furthermore, this setup ensures that while implementing multi-gate driving, each data signal line provides data to only one color's sub-pixel, preventing color crosstalk issues when charging time is insufficient. This allows for a reduction in the number of source driver chips without eliminating color crosstalk.

[0105] On the other hand, for liquid crystal display panels, the screen displays images by applying voltage to the liquid crystal to adjust its deflection angle. However, in order to avoid deflection failure due to the long-term use of the same charging polarity, the polarity of the data signals received by the data signal lines has a difference between positive and negative polarity, and the polarity is switched at predetermined time intervals.

[0106] In a practical circuit, the source driver chip includes a positive polarity channel and a negative polarity channel, which are usually arranged alternately. An inverting circuit can also be included between the source driver chip and the data signal line to switch the connection relationship between the positive polarity channel and the negative polarity channel and the data signal line at a predetermined time interval, thereby causing the polarity of the data signal line to change at a predetermined time interval.

[0107] However, when the data polarity of the data signal lines connected to the same color sub-pixels in a row of pixel units along the x-direction is different, a screen boundary problem will occur.

[0108] To address this issue, in this embodiment, the data signal lines electrically connected to sub-pixels of the same color have the same polarity, thereby ensuring that all sub-pixels of the same color in a row of pixel units are connected to the same polarity, thus preventing screen boundary division.

[0109] Specifically, refer to Figure 5 As shown in the figure, the first data signal line S1 and the fourth data signal line S4 are both electrically connected to the red sub-pixel. At the same time, these two data signal lines are also electrically connected to the positive polarity data. Of course, when the polarity is reversed, these two data signal lines are also electrically connected to the negative polarity data, thus ensuring that the polarity is consistent and no screen boundary occurs.

[0110] Because the channels of source driver chips are usually set with alternating positive and negative polarities, in order to achieve Figure 5 Due to polarity requirements, one channel in every three channels of the source driver chip is idle. That is, assuming that starting from the first channel of the source driver chip, and sequentially connected to the data lines beginning with the first data signal line, then the first channel s1 is electrically connected to data signal line S1, the second channel s2 is electrically connected to data signal line S2, the third channel s3 is electrically connected to data signal line S3, the fourth channel s4 is idle, the fifth channel s5 is electrically connected to data signal line S4, the sixth channel s6 is electrically connected to data signal line S5, the seventh channel s7 is electrically connected to data signal line S6, the eighth channel s8 is idle, and so on. (Further details omitted.)

[0111] This method avoids screen demarcation during the LCD panel driving process. Of course, not all channels in the source driver chip can be utilized. For example, using a single 3840CH source driver chip can achieve a 2880RGB resolution display. Naturally, as a multi-gate driving method, the y-axis resolution is 1 / 3 of that of a single-gate driving method, or the refresh rate is 1 / 3 of that of a single-gate driving method.

[0112] However, Figure 6 In the example shown, although there is no screen division issue for the LCD panel, the number of positive and negative data signal lines differs significantly for the entire display panel during each frame display. Therefore, when the polarity switches, this difference in the number of positive and negative polarities will cause a flicker that is perceptible to the human eye.

[0113] Considering this issue, refer to Figure 7 As shown, the polarity setting of the data signal line can be adjusted.

[0114] Specifically, the data signal lines electrically connected to sub-pixels of the same color in adjacent columns of pixel units arranged along the first direction have the same polarity.

[0115] In other words, in this example, instead of using the connection method where the source driver chip channels are idle, the characteristic of the positive and negative polarity channels of the source driver chip is utilized, and the channels of the source driver chip are sequentially electrically connected to the data signal lines.

[0116] Specific reference Figure 7 As shown, if the first channel s1 of the source driver chip is electrically connected to the data signal line S1, then the first channel s1 to the sixth channel s6 are electrically connected to the data signal lines S1 to S6 in sequence. Thus, if the sub-pixels that currently receive positive polarity data are in 3 columns and the sub-pixels that receive negative polarity data are in 3 columns, after a polarity switch occurs, the sub-pixels that receive positive polarity data will also receive 3 columns and the sub-pixels that receive negative polarity data will also receive 3 columns, thus preventing screen flicker and solving the flicker problem.

[0117] Furthermore, this configuration ensures no loss of channels in the source driver chip, allowing the same chip to provide higher resolutions. For example, a single 3840CH driver chip can achieve a 3840RGB resolution display.

[0118] However, this setting can cause screen boundaries because subpixels of the same color in the pixel unit row along the x-direction receive data of different polarities.

[0119] It should be noted that, referring to Figure 7 As shown, in this example, the structure other than the polarity setting of the data signal lines is the same as... Figure 6 The example shown is the same; the same effect of no color mixing can be achieved in the case of multi-gate driving, so it will not be elaborated here.

[0120] In another specific example, refer to Figure 8 As shown, if a pixel unit is composed of sub-pixels of four colors, that is, when the display panel implements four-gate driving, it can solve the problems of screen boundary and flicker at the same time by utilizing its structural characteristics.

[0121] Specifically, refer to Figure 8 As shown, pixel unit 10-3 includes a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel, where the third sub-pixel is a third color and the fourth sub-pixel is a fourth color. For example, pixel unit 10-3 includes a red sub-pixel R, a green sub-pixel G, a blue sub-pixel B, and a white sub-pixel W.

[0122] Pixel unit 10-3 includes four pixel islands arranged along a first direction, each pixel island including N sub-pixels of the same color arranged along a second direction, where N is an integer greater than or equal to 2. Figure 8 In the example shown, N is 4, but it is not limited to this.

[0123] Reference Figure 8 As shown, each pixel unit row along the second direction corresponds to 4 scan signal lines.

[0124] Each pixel unit 10-3 includes a group of first sub-pixels, second sub-pixels, third sub-pixels, and fourth sub-pixels arranged in a first direction. The third end of the driving unit of the group of first sub-pixels, second sub-pixels, third sub-pixels, and fourth sub-pixels is electrically connected to a scan signal line. The first end of the driving unit is electrically connected to a data signal line, and the second end is electrically connected to the sub-pixel. The data signal lines electrically connected to sub-pixels of the same color in adjacent columns of pixel units arranged along the first direction have the same polarity. The data signal lines electrically connected to sub-pixels of the same color have the same polarity. Furthermore, each of the data signal lines is electrically connected to a sub-pixel of the same color in the pixel units arranged along its extension direction.

[0125] As can be seen from this setup, for each pixel unit 10-3, the same column along the y-direction forms a group, and the control electrode of the driving transistor 20-3 is electrically connected to the same scan signal line, for example... Figure 8 The diagram shows two pixel units 10-3 located in the first pixel unit row. The control electrode of the driving transistor 20-3 of the first column of red sub-pixels R, green sub-pixels G, blue sub-pixels B, and white sub-pixels W in each pixel unit 10-3 is electrically connected to scan signal line G1. Other groups of sub-pixels are sequentially electrically connected to scan signal lines G2, G3, and G4. Simultaneously, sub-pixels of the same color in the same pixel unit column are all electrically connected to the same data signal line via the first electrode of their driving transistor 20-3. For example, the red sub-pixels R in the first pixel unit column are all electrically connected to data signal line S1, the green sub-pixels G are all electrically connected to data signal line S2, the blue sub-pixels B are all electrically connected to data signal line S3, and the white sub-pixels W are all electrically connected to data signal line S4.

[0126] Of course, the drive unit is not limited to Figure 8 The driving transistors shown will not be described in detail here.

[0127] With this setting, for a pixel unit 10-3, the scanning drive of the scanning signals of different scanning signal lines can enable the sub-pixels electrically connected to the same data signal line to be given different data signals in a time-division manner, thereby completing multi-gate driving. At the same time, there will be no color mixing of different colors even when the charging is insufficient.

[0128] In addition, through Figure 8The example shown illustrates that because a pixel unit 10-3 includes sub-pixels of four colors, and every four data signal lines form a group on the pixel column, the polarity of the data signal lines connected to the sub-pixels of the same color in adjacent pixel units arranged along the y-direction is the same. This ensures that the number of positive and negative data signal lines across the entire screen is equal, thus solving the screen boundary problem without the flicker problem.

[0129] Of course, with this setting, since each pixel unit 10-3 also requires four channels, the vertical resolution is 1 / 4 of that of a single-gate drive, or the refresh rate is 1 / 4 of that of a single-gate drive.

[0130] In another alternative embodiment, it is considered that while solving the color mixing problem, the display boundary and flicker problem of the RGB pixel unit display panel can also be solved simultaneously.

[0131] Refer to a specific example Figure 9 As shown, the display panel includes: multiple pixel units 10-4, multiple scan signal lines G1, G2, ..., G6 and multiple data signal lines S1, S2, ..., S6.

[0132] Similar to the example above, the data signal lines extend along the first direction (i.e., the y direction) and are arranged along the second direction (i.e., the x direction), and the scan signal lines extend along the second direction and are arranged along the first direction. The first and second directions intersect, but this embodiment is not intended to limit the first and second directions to the y and x directions shown in the figure.

[0133] In addition, also for convenience, Figure 9 Six scan signal lines G1, G2, ..., G6 and six data signal lines S1, S2, ..., S6 are shown, but this is merely illustrative and not intended to be limiting.

[0134] It is also understood that the display panel should include a gate driving circuit and a source driving circuit. Exemplarily, the source driving circuit can be specifically implemented as a source driving chip (e.g., a source IC), and the gate driving circuit can be, for example, a GOA circuit or a gate driving chip.

[0135] Optionally, each pixel unit 10-4 includes multiple sub-pixels, including a first sub-pixel, a second sub-pixel, and a third sub-pixel. The first sub-pixel is a first color, the second sub-pixel is a second color, and the third sub-pixel is a third color. The first color, the second color, and the third color are different. For example, the three color sub-pixels are red sub-pixel R, green sub-pixel G, and blue sub-pixel B, respectively.

[0136] To enable 3D display, pixel unit 10-4 includes three pixel islands arranged along a first direction, each pixel island including N sub-pixels of the same color arranged along a second direction, where N is an integer greater than or equal to 2. Specifically, in this example, N is 3. Of course, those skilled in the art will understand that this disclosure is not intended to limit the number of N; the larger the number of N, the richer the image information contained in the beam of light emitted by each color of a pixel unit during 3D display.

[0137] Optionally, each pixel unit row along the second direction corresponds to N scan signal lines. Each pixel unit includes a sub-pixel group arranged along the first direction, consisting of a first sub-pixel, a second sub-pixel, and a third sub-pixel. The third end of the driving unit of the sub-pixel in the sub-pixel group is electrically connected to a scan signal line. The N scan signal lines of two adjacent pixel unit rows are electrically connected in a one-to-one correspondence. The first end of the driving unit is electrically connected to a data signal line, and the second end is electrically connected to the sub-pixel.

[0138] In this arrangement, the data signal lines electrically connected to the sub-pixels of the same color in pixel units arranged along the first direction are of the same polarity, and the data signal lines electrically connected to the sub-pixels of the same color in adjacent pixel units are of opposite polarity. In the arrangement of pixel units along the second direction, the data signal lines electrically connected to the sub-pixels of the same color are of the same polarity.

[0139] In this embodiment, the rows of pixel units arranged along the x-direction are grouped, with two adjacent pixel units forming a group, and driven by the same timing scan signal.

[0140] Specifically, as an example, Figure 9 The image shows the first pixel unit in the first row (framed with a dashed box) and the first pixel unit in the second row (not framed with a dashed box).

[0141] The scan signal lines are grouped according to the number of pixel islands in each pixel unit 10⁻⁴. In this example, pixel unit 10⁻⁴ consists of 3 pixel islands, so each row of pixel units arranged along the x-direction corresponds to 3 scan signal lines. The first row of pixel units corresponds to scan signal lines G1, G2, and G3, and the second row of pixel units corresponds to scan signal lines G4, G5, and G6. The two groups of scan signal lines are electrically connected one-to-one. Specifically, scan signal line G1 is electrically connected to scan signal line G4, scan signal line G2 is electrically connected to scan signal line G5, and scan signal line G3 is electrically connected to scan signal line G6.

[0142] in addition, Figure 9In the diagram, the control electrodes of the driving transistors 20-4 of the first column sub-pixels of the first pixel unit 10-4 in the first row are all connected to the scan signal line G1. Similarly, the control electrodes of the driving transistors 20-4 of the first column sub-pixels of the first pixel unit 10-3 in the second row are all connected to the scan signal line G4. This means that the driving transistors 20-4 corresponding to these two columns of sub-pixels are simultaneously turned on. Likewise, the driving transistors 20-4 corresponding to the second column sub-pixels in both the first and second rows are simultaneously turned on, as are the driving transistors 20-4 corresponding to the third column sub-pixels.

[0143] Continue to refer to Figure 9 As shown, the first pixel unit 10-4 in the first row and the first pixel unit 10-4 in the second row are arranged correspondingly in the y direction and are in adjacent rows. The red sub-pixel R of the first pixel unit 10-4 in the first row is electrically connected to the data signal line S1 via the first electrode of the driving transistor 20-4, the green sub-pixel G is electrically connected to the data signal line S2 via the first electrode of the driving transistor 20-4, and the green sub-pixel B is electrically connected to the data signal line S3 via the first electrode of the driving transistor 20-4. The red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B of the first pixel unit 10-4 in the second row are electrically connected to the data signal lines S4, S5, and S6 respectively via the driving transistor 20-4.

[0144] With the above settings, scan signal lines G1 and G4 are simultaneously connected to the same scan signal, but the red sub-pixel R of the first column of the first row and the first column of the second row are written with different data signals via data signal lines S1 and S4 respectively, the green sub-pixel G is written with different data signals via data signal lines S2 and S5 respectively, and the blue sub-pixel B is written with different data signals via data signal lines S3 and S5 respectively. Scan signal lines G2 and G5 are simultaneously connected to the same scan signal, and data signal writing is completed via data signal lines S1 to S6 in the manner described above. Scan signal lines G3 and G6 are simultaneously connected to the same scan signal, and data signal writing is completed via data signal lines S1 to S6 in the manner described above.

[0145] With the above settings, since two pixel units are grouped together for data signal writing and scanning, it is equivalent to forming an even number of positive and negative data signal lines in the display panel by connecting two corresponding pixel units in the column of adjacent pixel units through their respective data signal lines. This ensures that flicker does not occur when the polarity is switched.

[0146] In addition, through the above settings, since the corresponding pixel units on adjacent columns form a data signal group, the polarity of the data signal lines of all sub-pixels of the same color in the pixel unit row arranged along the x-direction is the same, thereby avoiding screen boundaries.

[0147] Therefore, through the above settings, not only does each data signal line connect to only the same color data signal in the multi-gate driving mode, but color mixing will not occur when the charge is insufficient, and there will be no flicker or screen boundary.

[0148] However, the above settings will reduce the pixel resolution achieved by the source driver chip. For example, a single 3840CH driver chip can achieve a 3840RGB resolution display. The vertical resolution is 1 / 3 of that of a single-raster driver, or the refresh rate is 1 / 3 of that of a single-raster driver.

[0149] In another alternative embodiment, refer to Figure 10 As shown, another multi-grid driven 3D display driving solution is also provided.

[0150] The display panel includes: multiple pixel units 10-5, multiple scan signal lines G1, G2, ..., G9 and multiple data signal lines S1, S2, S3.

[0151] Similar to the example above, the data signal lines extend along the first direction (i.e., the y direction) and are arranged along the second direction (i.e., the x direction), and the scan signal lines extend along the second direction and are arranged along the first direction. The first and second directions intersect, but this embodiment is not intended to limit the first and second directions to the y and x directions shown in the figure.

[0152] In addition, also for convenience, Figure 10 Nine scan signal lines G1, G2, ..., G9 and three data signal lines S1, S2, S3 are shown, but this is merely illustrative and not intended to be limiting.

[0153] It is also understood that the display panel should include a gate driving circuit and a source driving circuit. Exemplarily, the source driving circuit can be specifically implemented as a source driving chip (e.g., a source IC), and the gate driving circuit can be, for example, a GOA circuit or a gate driving chip.

[0154] Optionally, each pixel unit 10-5 includes multiple sub-pixels, including a first sub-pixel, a second sub-pixel, and a third sub-pixel. The first sub-pixel is a first color, the second sub-pixel is a second color, and the third sub-pixel is a third color. The first color, the second color, and the third color are different. For example, the three color sub-pixels are red sub-pixel R, green sub-pixel G, and blue sub-pixel B, respectively.

[0155] To enable 3D display, pixel unit 10-5 includes three pixel islands arranged along a first direction, each pixel island including N sub-pixels of the same color arranged along a second direction, where N is an integer greater than or equal to 2. Specifically, in this example, N is 3. Of course, those skilled in the art will understand that this disclosure is not intended to limit the number of N; the larger the number of N, the richer the image information contained in the beam of light emitted by each color of a pixel unit during 3D display.

[0156] Optionally, the display panel includes a source drive circuit and an inverting circuit, wherein the source drive circuit is electrically connected to the data signal line via the inverting circuit.

[0157] Optionally, each pixel unit row along the second direction corresponds to N scan signal lines, and the third terminal of the driving unit of the same column of two adjacent sub-pixel rows along the second direction is electrically connected to the same scan signal line, the first terminal is electrically connected to the data signal line, and the second terminal is electrically connected to the sub-pixel. Each data signal line is electrically connected to a sub-pixel of the same color in the pixel units arranged along its extension direction. The inversion circuit is configured to, in a first time period within a frame of an image, conduct the positive terminal of the source driving circuit to the odd-numbered columns of data signal lines and conduct the negative terminal to the even-numbered columns of data signal lines; and in a second time period within a frame of an image, conduct the positive terminal of the source driving circuit to the even-numbered columns of data signal lines and conduct the negative terminal to the odd-numbered columns of data signal lines.

[0158] Specific combination Figure 10 and Figure 11 As shown, where Figure 10 This shows the specific settings for pixel driving in the display panel. Figure 11 Presented in tabular form Figure 10 An exemplary pixel driving timing of a display panel with this configuration shown includes... Figure 10 The pixel unit is shown in the figure, and to illustrate the specific driving method, the data signal lines S4 to S12 corresponding to other pixel units are also shown.

[0159] like Figure 10 The example shown is the first pixel unit 10-5 in the first pixel unit row and the second pixel unit row. In this example, the data writing of the two pixel units is completed by using 3×N scan signal lines as a group and N data signal lines as a group.

[0160] As shown in the figure, the third terminals of the driving units of sub-pixels located in the same column in the first and second rows are electrically connected to the same scan line. Specifically, the control electrodes of the driving transistors 20-5 of the first red sub-pixel R and the first green sub-pixel G in the first pixel unit row are electrically connected to scan signal line G1; the control electrodes of the driving transistors 20-5 of the second red sub-pixel R and the second green sub-pixel G in the first pixel unit row are electrically connected to scan signal line G2; and the control electrodes of the driving transistors 20-5 of the third red sub-pixel R and the third green sub-pixel G in the first pixel unit row are electrically connected to scan signal line G3. The third terminals of the driving units of sub-pixels located in the same column in the third and fourth rows are electrically connected to the same scan line. That is, in the second pixel unit row, the control electrode of the driving transistor 20-5 of the first red sub-pixel R and the first green sub-pixel G is electrically connected to the scan signal line G4; the control electrode of the driving transistor 20-5 of the second red sub-pixel R and the second green sub-pixel G in the second pixel unit row is electrically connected to the scan signal line G5; the control electrode of the driving transistor 20-5 of the third red sub-pixel R and the third green sub-pixel G in the second pixel unit row is electrically connected to the scan signal line G6. The third pixel unit row is similar, with corresponding two sub-pixels forming a group, and the control electrode of their driving transistors electrically connected to the same scan signal line.

[0161] At the same time, refer to Figure 10 As shown, in the two pixel units 10-5 arranged along the y-direction, all red sub-pixels R are electrically connected to the data signal line S1 via the first electrode of their driving transistor 20-5, all red sub-pixels G are electrically connected to the data signal line S2 via the first electrode of their driving transistor 20-5, and all red sub-pixels B are electrically connected to the data signal line S3 via the first electrode of their driving transistor 20-5.

[0162] Furthermore, in this example, data signal writing requires the assistance of an inversion circuit. The inversion circuit does not reverse the positive and negative polarity channels of the source driver circuit between frames; instead, it inverts the polarity of the data signal lines in groups of six, according to a preset rule. That is, the inversion circuit switches the polarity of the output terminals of the source driver circuit connected to each group of six data signal lines according to a preset rule, ensuring that the number of negative polarity data signal lines in a single frame is the same as the number of positive polarity data signal lines.

[0163] Reference Figure 11The driving timing shown in this example allows the inversion circuit to still reverse polarity in a way that swaps the positive and negative polarities. For instance, by using a preset rule, the data signal lines connected to the odd-numbered channels of some source drive circuits can be swapped with the data signal lines connected to the even-numbered channels, thus achieving polarity reversal. See the specific preset rule for details. Figure 11 As shown, polarity reversal cycles through six data signal lines in one cycle.

[0164] The second row of the diagram illustrates the initial polarity, i.e., the initial polarity of data signal line S1 is positive, the initial polarity of data signal lines S2 and S3 is negative, the initial polarity of data signal line S4 is positive, the initial polarity of data signal line S5 is negative, the initial polarity of data signal line S6 is positive, and so on, with data signal lines S7 to S12 repeating accordingly.

[0165] Combination Figure 10 As shown, when scan signal lines G1 to G3 are connected to scan signals with valid levels, the first red sub-pixel of the first red pixel island, the first green sub-pixel of the first green pixel island, the second red sub-pixel of the first red pixel island, the second green sub-pixel of the first green pixel island, the third red sub-pixel of the first red pixel island, and the third green sub-pixel of the first green pixel island are written to the data signal lines S1 and S2 respectively in sequence. During this period, the signal of data signal line S3 is not written.

[0166] When scan signal lines G4 to G6 are connected to valid scan signals, the first blue sub-pixel of the first blue pixel island, the first red sub-pixel of the second red pixel island, the second blue sub-pixel of the first blue pixel island, the second red sub-pixel of the second red pixel island, the third blue sub-pixel of the first blue pixel island, and the third red sub-pixel of the second red pixel island are sequentially written with data signals through data signal lines S3 and S1, respectively. During this period, the signal on data signal line S2 is not written. During this period, the inversion circuit reverses the polarity of the channels of the source drive circuit connected to data signal lines S1 and S2, and reverses the polarity of the channels of the source drive circuit connected to data signal lines S3 and S4. The polarity of data signal line S1 is negative, the polarity of data signal line S2 is positive, the polarity of data signal line S3 is positive, and the polarity of data signal line S4 is negative. The polarity of data signal lines S5 and S6 remains unchanged.

[0167] When scan signal lines G7 to G9 are connected to valid scan signals, the first green sub-pixel of the second green pixel island, the first blue sub-pixel of the second blue pixel island, the second green sub-pixel of the second green pixel island, the second blue sub-pixel of the second blue pixel island, the third green sub-pixel of the second green pixel island, and the third blue sub-pixel of the second blue pixel island are written to data signals through data signal lines S2 and S3 respectively. During this period, the signal of data signal line S1 is not written. During this period, the inverting circuit will swap the polarity of the source drive circuit channels connected to data signal lines S3 and S4, while keeping the polarity of data signal lines S1 and S2 unchanged. It will also swap the polarity of the source drive circuit channels connected to data signal lines S5 and S6. The polarity of data signal line S1 will remain negative, the polarity of data signal line S2 will remain negative, the polarity of data signal line S3 will be negative, the polarity of data signal line S4 will be positive, the polarity of data signal line S5 will be positive, and the polarity of data signal line S6 will be negative.

[0168] Of course, the way sub-pixels in the pixel units corresponding to data signal lines S4 to S6 write data is similar to that of data signal lines S1 to S3, and will not be elaborated on in this article.

[0169] As can be seen from this rule, in a single frame, when scan signal lines G1 to G9 are sequentially connected to valid levels, data signal lines S1 to S3 each have six valid level time periods writing data to the sub-pixel, with three time periods being positive and three being negative. Similarly, data signal lines S4 to S6 also have six valid level time periods writing data to the sub-pixel, with three time periods being positive and three being negative. It can be inferred that in a single frame, the total length of the positive and negative time periods for some data signal lines is the same, thus eliminating flicker. Furthermore, continuing to refer to… Figure 11 As shown, in a row of pixel units, the data signal lines S1, S4, S7 and S10 written to the red sub-pixel are all simultaneously positive or simultaneously negative, thus there is no screen boundary phenomenon.

[0170] Furthermore, through the above setup, using a set of 9 scan signal lines, only a set of 3 data signal lines and an inversion circuit are needed. This ensures that sub-pixels of the same color within the same column of pixel units are electrically connected to the same data signal line without reducing the resolution achieved by the source driver circuit. For example, a single 3840CH driver chip can achieve a 3840RGB resolution display.

[0171] Considering the characteristics of the data arrangement in the above embodiments, in order to ensure that the correct data can be fed into the correct channel and then written into the correct pixel unit after data decoding, it is more preferably that the display panel further includes an encoding unit, which encodes the data signal in a macroblock manner, and the data signal of the same pixel unit is encoded in one macroblock.

[0172] With the above settings, taking the H264 compression method with a 16×16 macroblock as the smallest coding unit as an example, in order to ensure the continuity of compression, 256 macroblocks are encoded continuously, and each macroblock encodes the data of one pixel unit, so that the decoded data is continuous and can be arranged in the manner described above.

[0173] Based on the same inventive concept, embodiments of this disclosure also provide a display device, including the gate driving circuit described in the above embodiments.

[0174] Since the display panel included in the display device provided in this embodiment corresponds to the display panel provided in the above embodiments, the previous embodiments are also applicable to this embodiment, and will not be described in detail in this embodiment.

[0175] In this embodiment, the display device can be any product or component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, in-vehicle display, digital photo frame or navigator. By loading the above display panel, the display device can have better display effect, higher competitiveness and broad application prospects.

[0176] This disclosure addresses existing problems by providing a display panel and display device. By electrically connecting each data signal line to at least a portion of the sub-pixels of the same color arranged along its extension direction, a data signal line provides data signals only to sub-pixels of the same color. This avoids color deviation and cross-contamination caused by incorrect charging of different colors during charging, improves the display effect, and has broad application prospects.

[0177] Obviously, the above embodiments of this disclosure are merely examples for clearly illustrating this disclosure, and are not intended to limit the implementation of this disclosure. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all implementation methods here. Any obvious variations or modifications derived from the technical solutions of this disclosure are still within the protection scope of this disclosure.
