[0004] Thin-film transistor liquid crystal displays (TFT-LCDs) are increasingly widely used. People have higher and higher requirements for the performance of liquid crystal displays, and at the same time, stricter requirements for the picture quality. Wide viewing angle, high contrast, low power consumption, and fast response are the main directions for improving the performance of displays. A liquid crystal panel generally includes an array substrate and a color filter substrate arranged in a cell, with liquid crystal molecules filled therebetween; the liquid crystal molecules change their positions by voltage.

Common inversion driving methods include row inversion driving method, column inversion driving method, frame inversion driving method, and dot inversion driving method.

[0005] However, different driving methods require different driving architectures, which makes the driving methods extremely limited. Therefore, it has become an urgent problem to use one driving architecture to achieve different driving methods. Summary of the Invention

[0023] The present application will be described in detail below with reference to the drawings and optional embodiments.

[0024] As Figure 1-2 shown, as an embodiment of the present application, a display device 1 is disclosed. The display device 1 includes a display panel 100 and a driving circuit 200 for driving the display panel 100. The display panel 100 includes: a first group of scan lines 110, a second group of scan lines 120, pixel units 150, data lines 140, and a switching module 160; the pixel units 150 are arranged in an array; the data lines 140 include multiple ones. When the first group of scan lines 110 or the second group of scan lines 120 is turned on, the data lines 140 provide data signals for the pixel units 150 of the display panel 100; wherein, the switching module 160 is used 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;

[0025] In the first display mode, the switching module 160 controls the first group of scan lines 110 to be turned on. When each data line 140 is turned on by the first group of scan lines 110, it provides data signals of the same polarity for the corresponding pixel units 150 to charge the corresponding pixel units 150; in the second display mode, the switching module 160 controls the second group of scan lines 120 to be turned on. When each data line 140 is turned on by the second group of scan lines 120, it provides data signals of the same polarity for the corresponding pixel units 150 to charge the corresponding pixel units 150.

[0026] Compared with the solution of implementing different driving methods by changing the driving signal, the present application directly changes on the driving architecture; the present application divides the scan lines into a first group of scan lines 110 and a second group of scan lines 120, and controls the first group of scan lines 110 and the second group of scan lines 120 respectively through the switching module 160. At the hardware level, the problem that different driving methods require different driving structures is solved, and it is realized that only one hardware switch is needed to realize the switching of different display modes.

[0027] It should be noted that different driving architectures correspond to different display modes here, and the present application integrates different driving architectures into one driving architecture. Here, the scan lines are divided into a first group and a second group, not into different types of scan lines. Instead, when the scan lines on the display panel 100 are opened in different display modes, the required scan lines are divided into the first group of scan lines 110 or the second group of 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-row column inversion. The following will be described in combination with a specific driving architecture.

[0028] As Figure 2 shown, as a specific 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, pixel units 150, data lines 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 scan lines 111 and one of the second scan lines 121;

[0029] In the first display mode, among the plurality of first scan lines 111, the 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, among the plurality of second scan lines 121, two adjacent second scan lines 121 form a group of second scan lines 121, and the polarities of the pixel units 150 in the same column corresponding to two adjacent groups of second scan lines 121 are different.

[0030] In the first display mode of the present application, the polarities of adjacent two rows of pixel units 150 are different, that is, the corresponding polarities are "+-+-"; in the second display mode, among adjacent four rows of pixel units 150, for the pixel units 150 in the same column, the corresponding polarities are "++--". Between adjacent frames, the polarities corresponding to the first display mode are "-+-+"; the polarities corresponding to the second display mode are "--++". Of course, the "+-+-" and "++--" mentioned here are only examples, and in actual selection, they can be "-+-+" or "--++", which are not limited herein. In this embodiment, adjacent data lines 140 provide data signals with different polarities for the pixel units 150. For each data line 140, the polarity is not inverted within one frame. The present application uses a column inversion driving method to achieve the display effect of dot inversion. Since the polarity switching frequency of the column inversion driving method is much lower than that of the dot inversion driving method, the column inversion driving method is power-saving. The dot inversion display effect is achieved by driving dot inversion through the column inversion driving method.

[0031] Specifically, the first scan line 111 and the second scan line 121 corresponding to the same row of pixel units 150 are respectively arranged above or below the pixel units 150 in that row, that is, 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 commonly used horizontally arranged scan lines and vertically arranged data lines 140 in the display panel 100. The pixel units 150 are also arranged in a matrix in the horizontal and vertical directions.

[0032] As Figure 3 shown, the display panel 100 further includes a plurality of first active switches 113 and a plurality of second active switches 123; the gates of the first active switches 113 are connected to the corresponding first scan lines 111; the gates of the second active switches 123 are connected to the corresponding second scan lines 121; one pixel unit 150 is respectively connected to the drain of one first active switch 113 and the drain of one second active switch 123; among them, in the same column of pixel units 150, the sources of adjacent two first active switches 113 are respectively connected to different data lines 140; adjacent two second active switches 123 are a group of second active switches 123, and the sources of adjacent two groups of second active switches 123 are respectively connected to different data lines 140. That is, on the same data line 140, the first active switches 113 corresponding to adjacent two rows of pixel units 150 are a 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 second-type active switches are connected to the data line 140.

[0033] As Figure 3Taking the display panel 100 shown as an 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 is provided with a first active switch 113 and a second active switch 123 correspondingly. Taking the first column pixel unit 150 in the first row pixel unit 150 to the fourth row pixel unit 150 as an example, the first active switch 113 and the second active switch 123 corresponding to the first column pixel unit 150 in the first row are respectively connected to the data line S2; the first active switch 113 corresponding to the first column pixel unit 150 in the second row 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 first column pixel unit 150 in the third row 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 first column pixel unit 150 in the fourth row are respectively connected to the data line S1. This arrangement is only a specific embodiment corresponding to the above solution. Among them, taking four adjacent row pixel units 150 as a group, the arrangement order within the group can be changed; it is not limited here.

[0034] When displaying in the first display mode, only the first group of scan lines 110 is turned on, and the corresponding first active switch 113 is turned on to charge the corresponding pixel unit 150. When displaying in the second display mode, only the second group of scan lines 120 is turned on, and the corresponding second active switch 123 is turned on to charge the corresponding pixel unit 150. In this embodiment, the same data line 140 provides only one polarity of data signal within one frame, and provides data signals of different polarities in adjacent frames. Moreover, the polarities of two adjacent data lines 140 are different.

[0035] Thus, it can be realized that in the first display mode, within the same frame, the polarities of two adjacent pixel units 150 are different, so as to realize dot inversion. Between adjacent frames, the polarities of the same pixel unit 150 are different. Corresponding Figure 4 is the polarity change of the first display mode, Figure 5The polarity change for the second display mode. Corresponding to the second display mode, within the same frame, the polarities of every two rows of pixel units 150 are the same, and the polarities of adjacent pixel units in a column are different, that is, two columns are inverted (2-Line inversion). Between adjacent frames, the polarities of the same pixel unit 150 are different. The first display mode uses a column inversion driving method to achieve the display effect of dot inversion. Since the polarity switching frequency of the column inversion driving method is much lower than that of the dot inversion driving method, the column inversion driving method is power-saving, but the display effect of dot inversion is better than that of column inversion. The second display mode uses a column inversion driving method to achieve a good 2-Line inversion display effect and has a better viewing angle. In actual use, the required scan line driving is selected according to different display modes. In the exemplary technology, if the polarity of the data line 140 within a frame is changed to achieve the 2-Line inversion display effect through the first group of scan lines 110, the power consumption will be large; and when using the second group of scan lines 120 to drive to achieve the dot inversion display effect, the polarity of the data line 140 within a frame will also be changed, resulting in an increase in power consumption. Therefore, this embodiment has the effect of reducing power consumption.

[0036] It should be noted that the arrangement order of the pixel units 150 of the present application is as follows: for example, a column of pixel units 150 corresponding to the first data line S1 are all red pixels R, a column of pixel units 150 corresponding to the second data line S2 are all green pixels G, and a column of pixel units 150 corresponding to the third data line S3 are blue pixels B. And in the direction of one row of scan lines, RGB are arranged in sequence. Each R pixel or G pixel or B pixel is set corresponding to one data line 140, and the corresponding data line 140 provides pixel voltage for the pixel unit 150. Moreover, the arrangement order of the three pixel units 150 from the first column data line 140 to the third column data line 140110 can be RGB, GBR, BRG, etc., and the arrangement order is not limited herein.

[0037] Specifically, the ways for the switching module 160 to implement the switching between the first display mode and the second display mode in hardware can be divided into the following two embodiments:

[0038] As Figure 6 shown, the display panel 100 includes a first scan driving circuit 112 and a second scan driving circuit 122. The switching module 160 controls the first scan driving circuit 112 to drive the first group of scan lines 110 to turn on; the switching module 160 controls the second scan driving circuit 122 to drive the second group of scan lines 120 to turn on; the first scan driving circuit 112 and the second scan driving circuit 122 are arranged on different sides of the display panel 100.

[0039] In this embodiment, different scan driving circuits are arranged on both sides to drive the first scan line 111 and the second scan line 121 respectively. The different scan driving circuits are controlled by a switching module 160, and can be freely selected when different display modes are required. Moreover, only one more driving circuit on one side needs to be added. And in practical applications, the switching module 160 can make dynamic selections, that is, the first display mode can be used in the previous frame and the second display mode can be used in the current frame. This method can be applied to high frame rate displays, such as 60HZ and 120HZ. Within 1 second, half of the selections are the first display mode and half are the second display mode.

[0040] For the switching module 160, another dynamic selection can also be made. After the current row of pixel units 150 is charged through the first scan line 111 in the current frame, the second scan line 121 corresponding to the current row of pixel units 150 can be turned on in the next frame, and the second scan line 121 is used to discharge the current row of pixel units 150, so that there is a certain gray scale difference between the current row of pixel units 150 and the previous row of pixel units 150, and the wide-angle display effect is better.

[0041] It should be noted that for a large-size panel that requires a display panel 100 with dual-sided simultaneous driving, a second scan driving circuit 122 can also be set on both sides at the same time without mutual influence. Of course, there is another way, as follows:

[0042] As Figure 7 shown, 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; the control ends of the plurality of P-type switches 161 and the control ends of the plurality of N-type switches 162 are connected to the control signal line 163; the first scan line 111 and the second scan line 121 corresponding to each row of pixel units 150 are respectively connected to the same scan driving line 130 through the corresponding P-type switch 161 and N-type switch 162.

[0043] In this embodiment, the first group of scan lines 110 and the second group of scan lines 120 are turned on through different switches. Moreover, in this embodiment, the driving circuits on both sides can be used to separately turn on the first group of scan lines 110 and the second group of scan lines 120 only through the control of the switching module 160.

[0044] As Figure 8As shown, 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 set of scan lines 110 includes a plurality of first scan lines 111, and the second set 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; taking four adjacent rows of the pixel units 150 as a group of the pixel units 150, in a group of the pixel units 150, each row of the pixel units 150 corresponds to one of the first scan lines 111, and only two rows of the pixel units 150 correspond to one of the second scan lines 121; in the 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 scan lines 111 are different; the sources of the corresponding two adjacent first active switches 113 are respectively connected to different data lines 140; in the 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 the two second scans are different; the sources of the corresponding two second active switches 123 are respectively connected to different data lines 140; in the second display mode, only the pixel units 150 corresponding to the first scan line 111 are driven by the first set of scan lines 110.

[0045] Specifically, in a group of the pixel units 150, the second row of the pixel units 150 and the third row of the pixel units 150 respectively correspond to one of the second scan lines 121. In this embodiment, respectively Figure 3 the first scan line 111 and the second scan line 121 corresponding to the first row of pixel units 150 are merged into one scan line, which can reduce the routing setting, thereby improving the aperture ratio.

[0046] It should be noted that among the first row to the fourth row of pixel units 150, the first row of pixel units 150 corresponds to only one scan line, and the second row corresponds to the first scan line 111 and the second scan line 121. During the driving process, the scan line of the first row is a common scan line, that is, whether it is the first display mode or the second display mode, the scan line of the first row is driven. That is, corresponding to Figure 8 in, for the row of pixel units 150 where one row of pixel units 150 corresponds to one first scan line 111, the corresponding first scan line 111 is the common scan line. Different from the previous embodiment, in a group of the pixel units 150, the first row of the pixel units 150 and the fourth row of the pixel units 150 respectively correspond to one of the second scan lines 121.

[0047] It should be noted that the inventive concept of this application can form a very large number of embodiments. However, due to the limited space of the application documents, it is impossible to list them all. Therefore, on the premise of no conflict, the above-described embodiments or technical features can be arbitrarily combined to form new embodiments. After the combination of each embodiment or technical feature, the original technical effect will be enhanced.

[0048] The technical solution of this application can be widely used in various display panels, such as TN (Twisted Nematic) display panels, IPS (In-Plane Switching) display panels, VA (Vertical Alignment) display panels, MVA (Multi-Domain Vertical Alignment) display panels. Of course, it can also be other types of display panels, and the above solutions are applicable.

[0049] The above content is a further detailed description of this application in combination with specific optional implementation manners. It cannot be determined that the specific implementation of this application is only limited to these descriptions. For those of ordinary skill in the technical field to which this application belongs, without departing from the concept of this application, several simple deductions or substitutions can be made, and all should be regarded as belonging to the protection scope of this application.
