AI Technical Summary
When the existing display devices reverse the display point, the data signal needs to be switched continuously, resulting in high power consumption and cannot meet the product needs with high resolution.
Adopt a novel connection framework, adjacent sub -pixels are connected to adjacent data cables, respectively. In a frame display screen, the voltage of the two adjacent data cables is greater than the reference voltage, and the other is less than the reference voltage. During the frame, the voltage polarity on the data cable reverses, thereby reducing the voltage swinging range on the data cable.
Reduce the voltage swing range on the data cable, thereby reducing power consumption. Under the gray step screen, the data cable has no pressure differential switch, which can realize the uniform charging of the pixel and improve the uniformity of the pixel display screen.

[0049] Multiple data lines;
[0050] Multiple scan lines;
[0051] A plurality of sub-pixels arranged in a matrix;
[0052] The number of data lines is less than or equal to 7 / 12 of the number of sub-pixels in the row direction, and the number of scan lines is greater than or equal to 5 / 2 of the number of sub-pixels in the column direction. Since the source driver IC is more expensive, the number of source driver ICs can be reduced to save costs.
[0053] Among them, at least four columns of sub-pixels are arranged between the first data line and the third data line of each of the three adjacent data lines; three columns of sub-pixels are arranged between the second data line and the first data line of each of the three adjacent data lines, or three columns of sub-pixels are arranged between the second data line and the third data line; specifically, assuming that the three adjacent data lines are the first data line D1, the second data line D2, and the third data line D3, that is, there are at least four columns of sub-pixels between the first data line D1 and the third data line D3, such as four columns, five columns, or six columns or more, which are selected according to specific usage requirements. Now, taking the case where four columns of sub-pixels are arranged between the first data line D1 and the third data line D3 as an example, that is, three columns of sub-pixels are arranged between the first data line D1 and the second data line D2, and one column of sub-pixels is arranged between the second data line D2 and the third data line D3, or one column of sub-pixels is arranged between the first data line D1 and the second data line D2, and three columns of sub-pixels are arranged between the second data line D2 and the third data line D3;
[0054] When the number of data lines increases, it is assumed that there are five data lines, namely the first data line D1, the second data line D2, the third data line D3, the fourth data line D4, and the fifth data line D5, that is, three columns of sub-pixels are arranged between the first data line D1 and the second data line D2, one column of sub-pixels is arranged between the second data line D2 and the third data line D3, three columns of sub-pixels are arranged between the third data line D3 and the fourth data line D4, and one column of sub-pixels is arranged between the fourth data line D4 and the fifth data line D5, so as to realize the first data line D1 to the fifth data line D5. Data line D5, the number of sub-pixels between adjacent data lines is distributed in a "3 / 1 / 3 / 1" pattern, or one column of sub-pixels is provided between the first data line D1 and the second data line D2, three columns of sub-pixels are provided between the second data line D2 and the third data line D3, one column of sub-pixels is provided between the third data line D3 and the fourth data line D4, and three columns of sub-pixels are provided between the fourth data line D4 and the fifth data line D5, so that from the first data line D1 to the fifth data line D5, the number of sub-pixels between adjacent data lines is distributed in a "1 / 3 / 1 / 3" pattern;
[0055] When the number of data lines continues to increase, they can continue to be arranged according to the above sub-pixel arrangement rule, which effectively reduces the number of data lines and reduces costs.
[0056] Two rows of sub-pixels are arranged between the first scan line and the sixth scan line of each of the six adjacent scan lines. Preferably, the number of sub-pixels connected to each scan line should be close, so as to improve the uniformity of the display panel when displaying each frame;
[0057] Three scan lines are arranged between each row of sub-pixels and one of the adjacent rows of sub-pixels on one side, and two scan lines are arranged between each row of sub-pixels and the adjacent rows of sub-pixels on the other side. Taking five scan lines and two rows of sub-pixels as an example, the five scan lines are respectively the first scan line G1, the second scan line G2, the third scan line G3, the fourth scan line G4, and the fifth scan line G5, and the two rows of sub-pixels are respectively the first row of sub-pixels and the second row of sub-pixels, that is, the first row of sub-pixels are arranged between the first scan line G1 and the second scan line G2, and the second row of sub-pixels are arranged between the third scan line G3 and the fourth scan line G4, or between the fourth scan line G4 and the fifth scan line G5; or the first row of sub-pixels are arranged between the second scan line G2 and the third scan line G3, and the second row of sub-pixels are arranged between the fourth scan line G4 and the fifth scan line G5;
[0058] When the number of scan lines and the number of rows of sub-pixels increases, assuming that there are eleven scan lines and four rows of sub-pixels, the ten scan lines are respectively the first scan line G1, the second scan line G2, the third scan line G3, the fourth scan line G4, the fifth scan line G5, the sixth scan line G6, the seventh scan line G7, the eighth scan line G8, the ninth scan line G9, the tenth scan line G10, and the eleventh scan line G11, and the four rows of sub-pixels are respectively the first row of sub-pixels, the second row of sub-pixels, the third row of sub-pixels, and the fourth row of sub-pixels, that is, the distribution of the scan lines and the rows of sub-pixels has the following four modes:
[0059] Mode 1: The first row of sub-pixels is arranged between the first scan line G1 and the second scan line G2, the second row of sub-pixels is arranged between the third scan line G3 and the fourth scan line G4, the third row of sub-pixels is arranged between the sixth scan line G6 and the seventh scan line G7, and the fourth row of sub-pixels is arranged between the eighth scan line G8 and the ninth scan line G9;
[0060] Mode 2: The first row of sub-pixels is arranged between the first scan line G1 and the second scan line G2, the second row of sub-pixels is arranged between the fourth scan line G4 and the fifth scan line G5, the third row of sub-pixels is arranged between the sixth scan line G6 and the seventh scan line G7, and the fourth row of sub-pixels is arranged between the ninth scan line G9 and the tenth scan line G10;
[0061] Mode 3: The first row of sub-pixels is arranged between the second scan line G2 and the third scan line G3, the second row of sub-pixels is arranged between the fourth scan line G4 and the fifth scan line G5, the third row of sub-pixels is arranged between the seventh scan line G7 and the eighth scan line G8, and the fourth row of sub-pixels is arranged between the ninth scan line G9 and the tenth scan line G10;
[0062] Mode 4: The first row of sub-pixels is arranged between the second scan line G2 and the third scan line G3, the second row of sub-pixels is arranged between the fifth scan line G5 and the sixth scan line G6, the third row of sub-pixels is arranged between the seventh scan line G7 and the eighth scan line G8, and the fourth row of sub-pixels is arranged between the tenth scan line G10 and the eleventh scan line G11;
[0063] When the number of scan lines continues to increase, they can be arranged according to any of the above sub-pixel arrangement rules according to specific usage requirements, which has a wide range of applications.
[0064] As an embodiment of the present invention, three columns of sub-pixels are arranged between the nth data line and the n+1th data line, n is an odd number, that is, starting from the first data line D1, the number of sub-pixels between adjacent data lines is distributed in a "3 / t-3 / 3 / t-3" pattern, wherein t is the number of columns of sub-pixels between the first data line and the third data line in every three adjacent data lines, and t≥4; a row of sub-pixels is arranged between the 1st+5mth scan line and the 2nd+5mth scan line, a row of sub-pixels is arranged between the 4th+5mth scan line and the 5th+5mth scan line, m≥0 and m is an integer, that is, a first row of sub-pixels is arranged between the first scan line and the second scan line, a second row of sub-pixels is arranged between the fourth scan line and the fifth scan line, three scan lines are arranged between the first row of sub-pixels and the second row of sub-pixels, and two scan lines are arranged between the second row of sub-pixels and the third row of sub-pixels, and the arrangement is carried out according to this rule.
[0065] As an embodiment of the present invention, sub-pixels located at the intersection of odd rows and odd columns are connected to the data lines of odd columns, sub-pixels located at the intersection of odd rows and even columns are connected to the data lines of even columns, sub-pixels located at the intersection of even rows and odd columns are connected to the data lines of even columns, and sub-pixels located at the intersection of even rows and even columns are connected to the data lines of odd columns. This ensures that each sub-pixel and the adjacent sub-pixel will not be connected to the same data line, avoiding the crossing of transistors connected to adjacent sub-pixels during the connection process, resulting in signal confusion, and further causing display abnormalities of the display panel. This can not only improve the safety and stability of the display panel, but also make the arrangement neat.
[0066] As an embodiment of the present invention, in the same frame, one of the voltages of two adjacent data lines is greater than a reference voltage, and the other is less than the reference voltage, that is, in the first frame, the voltage of the odd-numbered data lines is greater than the reference voltage, and the voltage of the even-numbered data lines is less than the reference voltage, and in the second frame, the voltage of the odd-numbered data lines is less than the reference voltage, and the voltage of the even-numbered data lines is greater than the reference voltage, and this is repeated in the third and fourth frames. Alternatively, in the first frame, the voltage of the odd-numbered data lines is less than the reference voltage, and the voltage of the even-numbered data lines is greater than the reference voltage, and in the second frame, the voltage of the odd-numbered data lines is greater than the reference voltage, and the voltage of the even-numbered data lines is less than the reference voltage, and this is repeated in the third and fourth frames. The sub-pixel inversion method is column inversion, so that each sub-pixel has an opposite polarity to the adjacent sub-pixel.
[0067] As an embodiment of the present invention, the display panel can choose to use three primary colors of red, green and blue, four primary colors of red, green, blue and white, four primary colors of red, green, blue and yellow, or five primary colors of red, green, blue, yellow and white according to specific usage requirements, and has a wide range of applications.
[0068] See also Figure 4 Assuming that the three primary colors of red, green and blue are used, taking the first frame as an example, the voltage of the odd-numbered data lines is greater than the reference voltage, and the voltage of the even-numbered data lines is less than the reference voltage, the polarity of each sub-pixel is opposite to the polarity of the adjacent sub-pixel, and as the frame number changes, the polarity of each sub-pixel changes simultaneously.
[0069] The present invention adopts a novel connection frame, and adjacent sub-pixels are respectively connected to adjacent data lines. In a frame of display, one of the voltages of two adjacent data lines is greater than a reference voltage, and the other is less than the reference voltage. In the next frame, the voltage polarity on the data line is reversed, so that the voltage of the data line does not need to change in a frame of display, avoiding data switching of the data line in a frame of display, and reducing the voltage swing amplitude on the data line, thereby reducing power consumption. In a grayscale image, the data line has no voltage difference switching, and uniform pixel charging can be achieved. At the same time, the driving method of the present invention adopts column driving to achieve dot inversion. Dot inversion means that when the writing of a frame of picture ends and before the writing of the next frame of picture begins, the voltage polarity stored in each sub-pixel is opposite to the voltage polarity of the adjacent sub-pixels above, below, left and right, and the voltage polarity stored in the same sub-pixel in two adjacent frames is also opposite, which can save power consumption and effectively improve the uniformity of pixel display.
[0070] See also Figure 2As an embodiment of the present invention, four columns of sub-pixels are arranged between the first data line and the third data line of every three adjacent data lines, and a repeating module is formed by seven adjacent data lines, five adjacent scan lines, and two rows of twelve columns of sub-pixels, and there is at least one repeating module; when there are two or more repeating modules, the repeating modules can be arranged along the row direction or the column direction, or can be arranged along the row direction and the column direction at the same time. Taking four repeating modules as an example, the four repeating modules are respectively a first repeating module, a second repeating module, a third repeating module, and a fourth repeating module, and there are three arrangement methods:
[0071] Mode 1: four repeating modules are arranged in sequence along the row direction, that is, the second repeating module is arranged on the right side of the first repeating module, the third repeating module is arranged on the right side of the second repeating module, and the fourth repeating module is arranged on the right side of the third repeating module. When the number of repeating modules continues to increase, the newly added repeating modules continue to be arranged in sequence along the row direction to the right of the fourth repeating module;
[0072] Mode 2: Four repeating modules are arranged in sequence along the column direction, that is, the second repeating module is arranged below the first repeating module, the third repeating module is arranged below the second repeating module, and the fourth repeating module is arranged below the third repeating module. When the number of repeating modules continues to increase, the newly added repeating modules continue to be arranged in sequence along the column direction below the fourth repeating module.
[0073] Method three: four repeating modules are arranged in a 2×2 array, that is, the second repeating module is arranged below the first repeating module, the third repeating module is arranged on the right of the first repeating module, and the fourth repeating module is arranged below the third repeating module. When the number of repeating modules continues to increase, the newly added repeating modules continue to be arranged along the row direction to the right of the third repeating module and the fourth repeating module, or continue to be arranged along the column direction below the second repeating module and the fourth repeating module. It is only necessary to ensure that all the repeating modules can be arranged in a regular column.
[0074] Preferably, when there are at least two repetitive modules along the row direction, the seventh data line of the repetitive module on the left and the first data line of the repetitive module on the right are the same data line.
[0075] As an embodiment of the present invention, in a repeating module,
[0076] For the sub-pixels located in the first row, the first sub-pixel and the third sub-pixel between the 1+2x data lines and the 2+2x data lines are connected to the 1+2x data lines; the second sub-pixel is connected to the 2+2x data lines;
[0077] The sub-pixels in the first row and the sub-pixels between the 2+2xth data line and the 3+2xth data line are all connected to the 2+2xth data line;

[0080] Here, x takes the value of 0, 1 or 2.
[0081] Assume that the five scan lines in the replication module are the first scan line G1, the second scan line G2, the third scan line G3, the fourth scan line G4, and the fifth scan line G5, the seven data lines are the first data line D1, the second data line D2, the third data line D3, the fourth data line D4, the fifth data line D5, the sixth data line D6, and the seventh data line D7, the first row of sub-pixels are sub-pixels S1 to sub-pixels S12 from left to right, the second row of sub-pixels are sub-pixels S13 to sub-pixels S24 from left to right, and the three primary colors of red, green, and blue are used;

[0105] The present invention provides a driving method based on the above-mentioned display panel, and the driving method comprises:
[0106] In one frame, a data voltage signal with a first polarity is output to the data lines located in odd columns, and a data voltage signal with a second polarity is output to the data lines located in even columns, wherein the first polarity is opposite to the second polarity;
[0107] In the next frame, data voltage signals with the second polarity are output to the data lines located in odd columns, and data voltage signals with the first polarity are output to the data lines located in even columns.
[0108] See also Figure 5 The present invention exemplifies the timing diagram of the data voltage signals of the first data line D1, the second data line D2, and the third data line D3 in one frame. It can be seen from the figure that the timing diagrams of the data voltage signals of the three data lines in one frame are all straight lines, that is, the voltage of the data line does not need to change in one frame display, avoiding data switching of the data line in one frame display, which can reduce the voltage swing amplitude on the data line, thereby reducing power consumption. There is no voltage difference switching of the data line under the grayscale picture, which can achieve uniform charging of pixels. Of course, the timing diagrams of the data voltage signals of other data lines in one frame are also straight lines.

[0112] In summary, the present invention provides a display panel and a driving method thereof, and a display device, which adopt a novel connection frame, and adjacent sub-pixels are respectively connected to adjacent data lines. In a frame of display, the voltage of two adjacent data lines is greater than a reference voltage, and the other is less than the reference voltage. In the next frame, the voltage polarity on the data line is reversed, so that the voltage of the data line does not need to change in a frame of display, avoiding data switching of the data line in a frame of display, and can reduce the voltage swing amplitude on the data line, thereby reducing power consumption. Under grayscale images, the data line has no voltage difference switching, and can realize uniform charging of pixels. At the same time, the driving method of the present invention adopts column driving to realize point inversion, which can not only save power consumption, but also effectively improve the uniformity of pixel display images; according to specific usage requirements, the number of data lines, the number of scanning lines and the number of sub-pixels in the replication module can be selected, which can meet the needs of various display panels, effectively increase the scope of application, and improve usage compatibility.
