s101, when detecting that a picture to be displayed is a preset picture, sequentially transmitting scanning signals to each scanning line, wherein the scanning signals are used for opening sub-pixels on each pixel row;

it should be understood that, among others, the above-described display panel includes: a plurality ofpixel rows 3 and a plurality ofpixel columns 4, wherein eachpixel row 3 is correspondingly connected with eachscanning line 1, and the coupling direction of eachsub-pixel 5 in anyadjacent pixel row 3 and thedata line 2 is opposite, eachpixel row 3 has a plurality ofsub-pixels 5, eachpixel column 4 has a plurality ofsub-pixels 5, as shown in fig. 2, thescanning line 1 of the nth row is coupled with thedata line 2 adjacent to the first direction side, thescanning line 1 of the (N + 1) th row is coupled with thedata line 2 adjacent to the second direction side, the first direction and the second direction are opposite, so that the polarity of the electrodes between anyadjacent pixel rows 3 is opposite; the first direction can be a left direction or a right direction, and the second direction is a direction opposite to the first direction; that is, when the first direction is a left direction, the second direction is a right direction; when the first direction is a right direction, the second direction is a left direction.

In the above example, the coupling directions of thesub-pixels 5 and thedata lines 2 in anyadjacent pixel rows 3 are opposite, and the polarities of the data signals output by anyadjacent data lines 2 are opposite, for example, if the polarity of the data signal output by the nthcolumn data line 2 is positive, the polarity of the data signal output by the N +1 thcolumn data line 2 is negative, so that the polarities of theadjacent sub-pixels 5 in eachpixel row 3 are opposite, and the polarities of theadjacent sub-pixels 5 in eachpixel column 4 are also opposite.

It should be understood that the execution main body for detecting whether the to-be-displayed frame is the preset frame is the driving IC, that is, the driving IC detects the to-be-displayed frame, and when the driving IC detects that the to-be-displayed frame is the preset frame, the driving IC sequentially transmits the scanning signals to thescanning lines 1, and the to-be-displayed frame is a frame to be displayed.

And S102, providing data signals to the data lines to drive the sub-pixels to display when the sub-pixels are turned on, wherein the polarities of the data signals received on the data lines of every two adjacent columns are opposite.

It should be understood that, taking the above example, the coupling directions of thesub-pixels 5 in anyadjacent pixel row 3 and thedata line 2 are opposite, so that when the polarities of the data signals transmitted on thedata lines 2 in every two adjacent columns are opposite, the polarities of every twoadjacent sub-pixels 5 in eachpixel row 3 are opposite, the polarities of anyadjacent sub-pixels 5 in eachpixel column 4 are opposite, and when the polarity of the electrode of thenth pixel column 4 is positive and the polarity of the electrode of the N +1th pixel column 4 is negative, the arrangement of eachsub-pixel 5 is as shown in fig. 3; when the polarity of the electrode of thenth pixel column 4 is negative and the polarity of the electrode of the (N + 1)th pixel column 4 is positive, the arrangement of thesub-pixels 5 is as shown in fig. 4.

In some examples of the embodiment, when detecting that the to-be-displayed frame is a preset frame, sequentially transmitting a scanning signal to eachscanning line 1 includes: acquiring the to-be-displayed state of each pixel group in eachpixel row 3, wherein each pixel group comprises: threeadjacent sub-pixels 5 of different colors; when the states to be displayed of any two adjacent pixel groups are opposite, the picture to be displayed is judged to be the preset picture, and scanning signals are sequentially transmitted to thescanning lines 1. It is to be understood that there are a plurality of pixel groups on eachpixel row 3, each pixel group including, but not limited to, adjacent: ared sub-pixel 5, agreen sub-pixel 5, and ablue sub-pixel 5, that is, a pixel group at least includes:sub-pixels 5 of three colors of RGB; the display state of eachsub-pixel 5 includes, but is not limited to: a light-emitting state and a light-off state, wherein the light-emitting state and the light-off state are opposite, when eachsub-pixel 5 in the pixel group is in the light-emitting state, the pixel group is determined to be in the light-emitting state, and when eachsub-pixel 5 in the pixel group is in the light-off state, the pixel group is determined to be in the light-off state.

Bearing the above example, wherein the preset pictures include but are not limited to: pixel on off picture; specifically, the driving IC may determine whether the picture to be displayed is a preset picture by obtaining the to-be-displayed state of each pixel group in the picture to be displayed, for example, as shown in fig. 3, when the to-be-displayed state of each pixel group in the nth row is a light-emitting state (white is a light-emitting state) and a light-off state (black is a light-off state), and the to-be-displayed state of each pixel group in the N +1 th row is a light-off state and a light-emitting state, the to-be-displayed states of any horizontal adjacent pixel group are opposite, and the to-be-displayed states of any vertical adjacent pixel group are also opposite, at this time, it is determined that the picture to be displayed is the preset picture; or, as shown in fig. 4, when the to-be-displayed states of the pixel groups in the nth row are sequentially arranged in an off state and a light-emitting state, and the to-be-displayed states of the pixel groups in the (N + 1) th row are sequentially arranged in a light-emitting state and an off state, the to-be-displayed states of any horizontal adjacent pixel groups are opposite, and the to-be-displayed states of any vertical adjacent pixel groups are also opposite, at this time, it is determined that the to-be-displayed picture is the preset picture.

It should be understood that when the states to be displayed of any adjacent pixel group are opposite, a greenish bias condition may occur, taking the quarter-resolution model as an example, as shown in fig. 5, the display panel includes a plurality of rows of scanning lines 1 (from G1-G1440), and a plurality of Data lines 2 (taking Data1 to Data12 as an example), the polarities of the Data signals transmitted by theadjacent Data lines 2 are opposite, eachscanning line 1 corresponds to apixel row 3, R in thepixel row 3 represents ared sub-pixel 5, G represents agreen sub-pixel 5, B represents ablue sub-pixel 5, the common voltage Vcom for driving eachscanning line 1 is set to 7V, the electrode of eachsub-pixel 5 in the light-emitting state is 14V or 0V, specifically, when thesub-pixel 5 is in the light-emitting state and has the positive polarity, the voltage of thesub-pixel 5 is 14v, and when thesub-pixel 5 is in a light-emitting state and has a negative polarity, the voltage of thesub-pixel 5 is 0 v; the voltage of eachsubpixel 5 in the off state is 7V; when the scanning of thescanning line 1 of the G1440 in the last line of the previous frame of picture is finished, Blanking and black insertion are carried out, when the voltage of eachsub-pixel 5 is 7V, the common voltage Vcom is normal 7V at the moment, and when the Blanking and black insertion (L0) is switched to the G1 in the first line, the voltage of thesub-pixel 5 connected with theData line 2 of Data4/Data5/Data6/Data10/Data11/Data12 is changed from 7V-7V to 0, and no voltage difference exists between thesub-pixels 5 connected with theData line 2; the voltage of thesub-pixel 5 connected with the Data1/Data3/Data7/Data9 Data line 2 is from 7V to 14V to + 7V; the voltage of thesub-pixel 5 connected to the Data2/Data8 Data line 2 is-7V from 7V to 0V, and at this time, the positive and negative polarities cannot be balanced due to four +7V and two-7V, which causes Vcom of the first row of scanning lines 1Gate1 to be coupled toward the positive electrode, and Vcom is coupled to 8V. At this time, the voltage difference between thered sub-pixel 5 and Vcom in the first row of Gate1 is 14V-8V-6V, the voltage difference between theblue sub-pixel 5 and Vcom is 14V-8V-6V, and the voltage difference between thegreen sub-pixel 5 and Vcom is 0V-8V, so that the voltage difference between thegreen sub-pixel 5 and the common electrode is greater than the voltage difference between thered sub-pixel 5 and theblue sub-pixel 5 and the common electrode, and further, eachgreen sub-pixel 5 is brighter than the original preset value, which results in the display panel showing a greenish picture.

In some examples of the present embodiment, sequentially transmitting the scan signal to therespective scan lines 1 includes: the scanning signals are sequentially transmitted to thescanning lines 1 starting with thescanning line 1 in the first row and ending with thescanning line 1 in the last row. That is, when the display panel displays a frame of picture, the frame is scanned from thefirst scanning line 1 to thelast scanning line 1 line by line; taking the QHD (Quarter High Definition, 1/4 for full High Definition) model as an example, scanning is performed from Gate1 to the last row of Gate1440 line by line, when the scanning of the last row ofscan line 1 is completed, the display of one frame of picture is completed, when the next frame of picture is displayed, the next frame of picture is returned to Gate1 and then scanned to the last row of Gate1440 line by line, it should be understood that, in some examples, two rows ofscan lines 1 at a time may also be scanned from Gate1 to the last row of scan line 1G1440 line by line.

In some examples of the present embodiment, before sequentially transmitting the scan signal to each of thescan lines 1, the method further includes: when the display of the current frame picture is finished, black insertion display is carried out in the vertical blanking stage of the frame picture; specifically, from the first row ofscan lines 1 to the last row ofscan lines 1, a period of time before the next frame of picture Gate1 is Blanking time, where the Blanking time is used to process noise generated by all previous scan lines 1Gate and wait for the signal transmission of the front-end IC, and the Blanking time needs to be processed by black insertion: after black pictures are inserted in the Blanking area, positive and negative polarity inversion is not needed, and therefore power consumption of the display panel is reduced.
