The wide viewing angle, high contrast, low power consumption and fast response are the main directions for improving the performance of the display, and the liquid crystal panel generally comprises an array substrate and a color film substrate which are arranged in a box-to-box manner, and liquid crystal molecules are filled between the array substrate and the color film substrate; the liquid crystal molecules change their position by a voltage. The polarity inversion driving is to apply a voltage signal with changed positive and negative polarities to the liquid crystal molecules to realize the alternating current driving of the liquid crystal molecules.

However, different driving schemes require different driving architectures, so that the driving schemes are very limited, and therefore, implementing different driving schemes by using one driving architecture becomes an urgent problem to be solved.

The present application is described in detail below with reference to the figures and alternative embodiments.

As shown in fig. 1 to 2, as an embodiment of the present application, a display device 1 is disclosed, the display device 1 including a display panel 100 and a driving circuit 200 driving the display panel 100, the display panel 100 including: a first group of scan lines 110, a second group of scan lines 120, a pixel unit 150, a data line 140, and a switching module 160; the pixel units 150 are arranged in an array; the data lines 140 include a plurality of data lines 140, and when the first group of scan lines 110 or the second group of scan lines 120 are turned on, the data lines 140 provide data signals for the pixel units 150 of the display panel 100; the switching module 160 is configured to switch the on states of the first group of scan lines 110 and the second group of scan lines 120; when the first group of scan lines 110 is turned on, the display panel 100 displays in a first display mode; when the second group of scan lines 120 is turned on, the display panel 100 displays in a second display mode;

in the first display mode, the switching module 160 controls the first group of scan lines 110 to be turned on, and each data line 140 provides data signals with the same polarity to the corresponding pixel unit 150 when the first group of scan lines 110 is turned on, so as to charge the corresponding pixel unit 150; in the second display mode, the switching module 160 controls the second group of scan lines 120 to be turned on, and each data line 140 provides the data signal with the same polarity to the corresponding pixel unit 150 when the second group of scan lines 120 is turned on, so as to charge the corresponding pixel unit 150.

Compared with a scheme of changing a driving signal to realize different driving modes, the method and the device are directly changed on a driving framework; the present application controls the first group of scan lines 110 and the second group of scan lines 120 by the switching module 160 by dividing the scan lines into the first group and the second group of scan lines 120, respectively. The problem that different driving modes need different driving structures is solved on the hardware level, and switching of different display modes can be realized only by one hardware switch.

It should be noted that the different display modes stated herein correspond to different driving architectures, and the present application merges the different driving architectures into one driving architecture. Here, the scan lines are divided into the first group and the second group, and when the scan lines on the display panel 100 are turned on in different display modes, the scan lines are divided into the first group scan lines 110 or the second group scan lines 120. The first display mode and the second display mode of the present application take polarity inversion as an example, respectively, the first display mode is a display mode driven by column inversion, and the second display mode is a display mode driven by two rows of column inversion, which is developed in combination with a specific driving architecture.

As shown in fig. 2, as an embodiment of the present application, a display panel 100 is disclosed, the display panel 100 includes: a first group of scan lines 110, a second group of scan lines 120, a pixel unit 150, a data line 140, and a switching module 160; the first group of scan lines 110 includes a plurality of first scan lines 111, and the second group of scan lines 120 includes a plurality of second scan lines 121; each row of the pixel units 150 is respectively arranged corresponding to one of the first scanning lines 111 and one of the second scanning lines 121;

in the first display mode, in the plurality of first scan lines 111, polarities of the pixel units 150 in the same column corresponding to two adjacent first scan lines 111 are different; in the second display mode, two adjacent second scan lines 121 in the plurality of second scan lines 121 form a group of second scan lines 121, and polarities of the pixel units 150 in the same column corresponding to the two adjacent groups of second scan lines 121 are different.

In the first display mode, the polarities of the two adjacent rows of pixel units 150 are different, i.e., the corresponding polarities are "+ - + -"; the second display mode is that in four adjacent rows of pixel units 150, the corresponding polarities of the pixel units 150 are "+ +". Between adjacent frames, the first display mode has a corresponding polarity of "- + - +"; the second display mode corresponds to a polarity of "- - +". Of course, the references to "+ - + -" and "+ + -" are merely illustrative and may be "+ - +" or "- + -" in practical choices. And are not intended to be limiting herein. In this embodiment, the adjacent data lines 140 provide data signals with different polarities to the pixel units 150. For each data line 140, no polarity inversion is performed within one frame. In the present application, the display effect of dot inversion is achieved by a column inversion driving method, and since the polarity switching frequency of the column inversion driving method is much lower than the polarity switching frequency of the dot inversion driving method, the column inversion driving method saves power. The dot inversion is driven by a column inversion driving mode, so that the dot inversion display effect is achieved.

Specifically, the first scan line 111 and the second scan line 121 corresponding to the same row of pixel units 150 are respectively disposed above or below the row of pixel units 150, i.e., the first scan line 111 and the second scan line 121 are located on different sides of the pixel units 150. It should be noted that the scan lines and the data lines 140 in the present application are the scan lines disposed horizontally and the data lines 140 disposed vertically, which are commonly found in the display panel 100. The corresponding pixel units 150 are also arranged in a matrix in the lateral and longitudinal directions.

As shown in fig. 3, the display panel 100 further includes a plurality of first active switches 113 and a plurality of second active switches 123; the gate of the first active switch 113 is connected to the corresponding first scan line 111; the gate of the second active switch 123 is connected to the corresponding second scan line 121; one of the pixel units 150 is correspondingly connected to the drain of one of the first active switches 113 and the drain of one of the second active switches 123, respectively; in the pixel unit 150 in the same column, the sources of two adjacent first active switches 113 are respectively connected to different data lines 140; two adjacent second active switches 123 are a group of the second active switches 123, and the sources of the two adjacent groups of the second active switches 123 are respectively connected to different data lines 140. On the same data line 140, the first active switches 113 corresponding to two adjacent rows of pixel units 150 are in one group, and the sources of every other group of first type active switches are connected to the data line 140; on the same data line 140, the sources of every other row of the second type active switches are connected to the data line 140.

As the display panel 100 shown in fig. 3 for example, the number of the first group of scan lines 110 and the second group of scan lines 120 is the same, and each pixel switch corresponds to one of the first active switches 113 and one of the second active switches 123, and taking the first row of pixel units 150 to the fourth row of pixel units 150 as an example, the first active switch 113 and the second active switch 123 corresponding to the first row of pixel units 150 and the first column of pixel units 150 are respectively connected to the data line S2; the corresponding first active switch 113 of the second row and the first column of pixel units 150 is connected to the data line S1, and the corresponding second active switch 123 is connected to the data line S2; the first active switch 113 corresponding to the pixel unit 150 in the third row and the first column is connected to the data line S2, and the corresponding second active switch is connected to the data line S1; the first active switch 113 and the second active switch 123 corresponding to the pixel unit 150 in the fourth row and the first column are respectively connected to the data line S1. This arrangement is only one embodiment of the above-mentioned scheme, wherein, the arrangement order in the group can be changed by grouping the adjacent four rows of pixel units 150; and are not limited herein.

When the display is performed in the first display mode, only the first group of scan lines 110 are turned on, and the corresponding first active switches 113 are turned on to charge the corresponding pixel units 150. When the display is performed in the second display mode, only the second group of scan lines 120 are turned on, and the corresponding second active switches 123 are turned on to charge the corresponding pixel units 150. In this embodiment, the same data line 140 provides data signals of only one polarity in one frame, and provides data signals of different polarities in adjacent frames. Also, the polarities of the adjacent two data lines 140 are different.

Thus, in the first display mode, the polarities of the two adjacent pixel units 150 are different in the same frame, so that dot inversion is realized. The polarity of the same pixel unit 150 is different between adjacent frames. Fig. 4 shows the polarity change of the first display mode, and fig. 5 shows the polarity change of the second display mode. For the second display mode, in the same frame, the polarities of the pixel units 150 in every two rows are the same, and the polarities of the units in the adjacent columns are different, i.e., two columns are inverted (2-Line inversion). The same pixel unit 150 has a different polarity between adjacent frames. In the first display mode, the display effect of dot inversion is achieved by the column inversion driving method, and the column inversion driving method saves power because the polarity switching frequency is much lower than the polarity switching frequency of the dot inversion driving method, but the display effect of dot inversion is better than the display effect of column inversion. The second display mode is that the display effect of 2-Line inversion realized by a column inversion driving mode is good, and the display mode has a better visual angle. In actual use, the required scanning line driving is selected according to different display modes. In an exemplary technique, if the display effect of 2-Line inversion is achieved by the first set of scan lines 110 by changing the polarity within one frame of the data lines 140, the power consumption will be large; and using the second group of scan lines 120 for driving, the display effect of dot inversion will also change the polarity of the data lines 140 within one frame, resulting in increased power consumption. This embodiment has the effect of reducing power consumption.

It should be noted that, in the pixel unit 150 arrangement order of the present application, for example, a column of pixel units 150 corresponding to the first data line S1 is all red pixels R, a column of pixel units 150 corresponding to the second data line S2 is all green pixels G, a column of pixel units 150 corresponding to the third data line S3 is blue pixels B, and RGB are sequentially arranged in a row scanning line direction, each R pixel or G pixel or B pixel is disposed corresponding to one data line 140, and the corresponding data line 140 provides a pixel voltage for the pixel unit 150. And the three pixel units 150 on the corresponding first column data line 140 to the third column data line 140110 may be arranged in the order of RGB, GBR, BRG, etc., and the arrangement order is not limited herein.

Specifically, the manner of implementing the switching between the first display mode and the second display mode by the switching module 160 can be divided into the following two embodiments:

as shown in fig. 6, the display panel 100 includes a first scan driving circuit 112 and a second scan driving circuit 122, and the switching module 160 controls the first scan driving circuit 112 to drive the first group of scan lines 110 to be turned on; the switching module 160 controls the second scan driving circuit 122 to drive the second group of scan lines 120 to be turned on; the first scan driving circuit 112 and the second scan driving circuit 122 are disposed on different sides of the display panel 100.

In this embodiment, different scan driving circuits are disposed on two sides to respectively drive the first scan line 111 and the second scan line 121, and the different scan driving circuits are controlled by the switching module 160, so that they can be freely selected when different display modes are required. And only one side of the driving circuit needs to be additionally arranged. In practical applications, the switching module 160 can perform dynamic selection, that is, the first display mode is used in the previous frame and the second display mode is used in the current frame, which can be applied in the high frame rate display, that is, 60HZ and 120HZ, within 1 second, half of the first display mode is selected and half of the second display mode is selected.

For the switching module 160, another dynamic selection may be performed, and after the current row of pixel units 150 is charged by the first scan line 111 in the current frame, the second scan line 121 corresponding to the current row of pixel units 150 is turned on by using the next frame, and the second scan line 121 is used to discharge the current row of pixel units 150, so that a certain gray level difference exists between the current row of pixel units 150 and the previous row of pixel units 150, and the wide-angle display effect is better.

It should be noted that, for a large-size panel, the display panel 100 requiring simultaneous driving on both sides may be provided with the second scan driving circuits 122 on both sides simultaneously without affecting each other. There is of course another way, as follows:

as shown in fig. 7, the switching module 160 includes a plurality of P-type switches 161, a plurality of N-type switches 162, and a control signal line 163; the display panel 100 further includes a plurality of scan driving lines 130; in the first group of scan lines 110, each first scan line 111 is correspondingly connected to a P-type switch 161; in the second group of scan lines 120, each second scan line 121 is correspondingly connected to an N-type switch 162; control terminals of the P-type switches 161 and control terminals of the N-type switches 162 are connected to the control signal line 163; the first scanning line 111 and the second scanning line 121 corresponding to each row of the pixel units 150 are respectively connected to the same scanning driving line 130 through the corresponding P-type switch 161 and the corresponding N-type switch 162.

The present embodiment realizes the turning on of the first group of scan lines 110 and the second group of scan lines 120 through different switches. Moreover, the present embodiment can use the double-sided driving circuit to respectively open the first group of scan lines 110 and the second group of scan lines 120 only by the control of the switching module 160.

As shown in fig. 8, as another embodiment of the present application, another display panel 100 is disclosed; the display panel 100 further includes a plurality of third active switches and a plurality of fourth active switches; the third active switch in this embodiment is the first active switch 111; the fourth active switch is the second active switch 112. The first group of scan lines 110 includes a plurality of first scan lines 111, and the second group of scan lines 120 includes a plurality of second scan lines 121; the gate of the third active switch is connected to the corresponding first scan line 111; the gate of the third active switch is connected to the corresponding second scan line 121; four adjacent rows of the pixel units 150 are taken as a group of the pixel units 150, in the group of the pixel units 150, each row of the pixel units 150 corresponds to one of the first scanning lines 111, and only two rows of the pixel units 150 are arranged corresponding to one of the second scanning lines 121; in a first display mode, in a group of the pixel units 150, the polarities of the pixel units 150 in the same column corresponding to two adjacent first scanning lines 111 are different; the sources of two corresponding adjacent first active switches 113 are respectively connected to different data lines 140; in a second display mode, in a group of the pixel units 150, the polarities of the pixel units 150 on the same data line 140 corresponding to two second scans are different; the sources of the two corresponding second active switches 123 are respectively connected to different data lines 140; in the second middle display mode, only the pixel units 150 disposed corresponding to the first scan lines 111 are driven by the first group of scan lines 110.

Specifically, in one group of the pixel units 150, the pixel units 150 in the second row and the pixel units 150 in the third row are respectively disposed corresponding to one of the second scan lines 121. In this embodiment, the first scan line 111 and the second scan line 121 corresponding to the first row of pixel units 150 in fig. 3 are respectively combined into one scan line, so that the routing arrangement can be reduced, and the aperture ratio can be improved.

It should be noted that, in the pixel units 150 in the first to fourth rows, the pixel unit 150 in the first row is disposed corresponding to only one scan line, and the pixel units in the second row are disposed corresponding to the first scan line 111 and the second scan line 121. The scanning lines of the first row are common scanning lines in the driving process, namely, the scanning lines of the first row are driven in the first display mode and the second display mode. That is, referring to fig. 8, for a row of pixel units 150 corresponding to a row of pixel units 150 disposed on one first scan line 111, the corresponding first scan line 111 is a common scan line. Unlike the previous embodiment, in one group of pixel units 150, the pixel units 150 in the first row and the pixel units 150 in the fourth row are respectively disposed corresponding to one second scanning line 121.
