[0096] The implementation of a frame of picture includes:
[0097] When the first scan line G1 is turned on, sub-pixels S3, S4, S6, S9, S13, S14 write corresponding sub-pixel data through the corresponding data lines, then sub-pixel S3 outputs blue sub-pixel data, sub-pixel S4 outputs red sub-pixel data, sub-pixel S6 outputs blue sub-pixel data, sub-pixel S9 outputs blue sub-pixel data, sub-pixel S13 outputs red sub-pixel data, and sub-pixel S14 outputs green sub-pixel data.

[0104] Of course, according to specific use requirements, the number of data lines, the number of scanning lines and the number of sub-pixels in the replication module can be selected, the required replication module is formed by increasing or reducing the number of data lines, the number of scanning lines and the number of sub-pixels, and the constructed replication module is arranged in an array manner, so that the requirements of various display panels can be met, the application range is effectively increased, and the use compatibility is improved.
[0105] The application provides a driving method based on the above display panel, and the driving method comprises the following steps:
[0106] In one frame of picture, data voltage signals with a first polarity are output to data lines located in odd columns, and data voltage signals with a second polarity are output to data lines located in even columns, wherein the first polarity is opposite to the second polarity.
[0107] In the next frame of picture, data voltage signals with the second polarity are output to data lines located in odd columns, and data voltage signals with the first polarity are output to data lines located in even columns.
[0108] Referring to Figure 5 The application exemplifies the time sequence 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 of picture, and it can be seen from the diagram that the time sequence diagrams of the data voltage signals of the three data lines in one frame of picture are all straight lines, that is, the voltage of the data line does not need to change in one frame of display, the data switching of the data line in one frame of display is avoided, the voltage swing amplitude on the data line is reduced, the power consumption is reduced, the data line is not switched with a pressure difference in the gray scale picture, the pixel uniform charging can be realized, and of course, the time sequence diagrams of the data voltage signals of other data lines in one frame of picture are also straight lines.
[0109] The application further provides a display device comprising the display panel, the source driver and the gate driver in any one of the above embodiments.
[0110] The source driver is connected with the data line and is used for providing a data signal to the display panel.
[0111] The gate driver is connected with the scan line and is used for providing a scan signal to the display panel.
[0112] In summary, the display panel, the driving method thereof and the display device provided by the present application adopt a novel connection framework, and adjacent sub-pixels are connected with adjacent data lines respectively. In a frame of display picture, the voltages of two adjacent data lines are greater than a reference voltage and smaller than the reference voltage respectively. When the next frame is reached, the voltage polarity on the data line is reversed. Therefore, the voltage on the data line does not need to be changed in a frame of display, and the data switching of the data line in a frame of display is avoided. The voltage swing amplitude on the data line can be reduced, and thus the power consumption is reduced. In a gray scale picture, the data line is not switched with a voltage difference, and the uniform charging of the pixel can be realized. Meanwhile, the driving method of the present application can realize the point inversion by using the column driving, and both the power consumption and the display picture uniformity of the pixel can be effectively improved. According to the specific use requirement, the number of the data lines, the number of the scan lines and the number of the sub-pixels in the copy module can be selected, and the requirement of various display panels can be met. The application range is effectively increased, and the use compatibility is improved.
[0113] It should be emphasized that the above are only the preferred embodiments of the present application, and do not limit the present application in any form. Any simple modification, equivalent change and modification made according to the technical essence of the present application to the above embodiments still belong to the scope of the technical solution of the present application.
