Description

A method for driving a display panel, and a display device

technical field

The present invention relates to the field of display technology, in particular to a method for driving a display panel and a display device.

Background technique

With the continuous development of liquid crystal display technology, the application of liquid crystal display devices is becoming more and more extensive. In order to prevent horizontal crosstalk and vertical crosstalk in the display screen of the liquid crystal display device, a dot inversion driving method is usually used to drive the display panel in the liquid crystal display device.

As shown in FIG. 1, the display panel includes a plurality of data lines 10' and a plurality of pixel units 20' arranged in an array, and the pixel units 20' scanned by each data line 10' are located at the same time as the data line 10'. side. Since each data line 10' scans the pixel unit 20' in the same way in the process of driving the display panel using the dot inversion driving method, so taking the first data line 10' in FIG. 1 as an example, the data line 10' is scanned The way of the pixel unit 20' is explained: as shown in Figure 2, in the same frame of picture, every time the data line 10' scans a pixel unit 20', the polarity of the data line driving signal is reversed once, so that in each column of pixel units In 20', the polarities of any two adjacent pixel units 20' are opposite. Among them, in Fig. 1 and Fig. 2, A', B', C', D' respectively represent the first row of pixel units, the second row of pixel units, the third row of pixel units and the fourth row of pixel units; in Fig. 2 Among them, +V means positive polarity, and -V means negative polarity. In addition, in the dot inversion driving mode, in each row of pixel units 20' in the same frame, the polarities of any two adjacent pixel units 20' are opposite; opposite polarity.

However, the inventors of the present application found during the research process that although the above-mentioned dot inversion driving method can ensure a better display effect on the display panel, since in the dot inversion driving method, each pixel unit scanned by the data line 10 ′ 20', the polarity of the data line driving signal is changed once, and the number of times of the polarity change of the data line driving signal is proportional to the power consumption, so the power consumption of the dot inversion driving method mentioned above is relatively high.

Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one

An embodiment of the present invention provides a method for driving a display panel, which is suitable for driving a display panel as shown in FIG. 3 . The display panel includes multiple data lines 10 and multiple pixel units 20 arranged in an array, each The pixel units 20 scanned by each data line 10 are all located on the same side of the data line 10, and the plurality of pixel units 20 in each column of pixel units 20 are divided into alternately arranged first pixel unit groups 21 and second pixel unit groups 22. A pixel unit group 21 and a second pixel unit group 22 respectively include one or two pixel units 20 .

For the display panel with the above structure, as shown in FIG. 4 and FIG. 5 , the driving method of the display panel provided by the embodiment of the present invention includes: in the same frame, each data line 10 sequentially scans all the first data lines in the corresponding column. After one pixel unit group 21, the polarity of the data line driving signal is reversed once, and then all the second pixel unit groups 22 in the corresponding column are scanned sequentially, and the initial data line driving signals of the two adjacent data lines 10 The polarity is opposite; the initial data line driving signals of two adjacent frames are opposite in polarity.

During the driving process of the display panel, in the same frame, after each data line 10 scans all the first pixel unit groups 21 in the corresponding column in sequence, the data line driving signal undergoes a polarity inversion, and then scans sequentially. Corresponding to all the second pixel unit groups 22 in the column, so that in each column of pixel units 20, the polarity of the pixel units 20 in the first pixel unit group 21 is the same as the polarity of the pixel units 20 in the second pixel unit group 22 On the contrary; and, the polarities of the initial data line driving signals of the two adjacent data lines 10 are opposite, so that in each row of pixel units 20, the polarities of the two adjacent pixel units 20 are opposite; The polarities of the initial data line driving signals of the frames are reversed, so that the polarities of the pixel units 20 in two adjacent frames are reversed. Moreover, in the same frame, after each data line 10 scans all the first pixel unit groups 21 in the corresponding column in sequence, the data line driving signal performs a polarity inversion, and then scans all the first pixel unit groups 21 in the corresponding column in sequence. The second pixel unit group 22 is such that when one data line 10 scans a column of pixel units 20 , the polarity of the data line driving signal changes only once.

In the above embodiment, because in the same frame, the polarity of the pixel units 20 in the first pixel unit group 21 in each column of pixel units 20 is opposite to the polarity of the pixel units 20 in the second pixel unit group 22 , the first pixel unit group 21 and the second pixel unit group 22 respectively include one or two pixel units 20, and the polarities of two adjacent pixel units 20 in each row of pixel units 20 are opposite; and in two adjacent frames of pictures The polarity of the pixel unit 20 is opposite, so that the polarity distribution of the pixel unit 20 obtained by the driving method of the display panel provided by the embodiment of the present invention is different from that of the pixel unit 20 obtained by the driving method in the prior art. The polarity distribution is the same or similar, so that the display effect obtained by the driving method of the display panel provided by the present invention is the same or similar to the display effect obtained by using the dot inversion driving method in the prior art, that is, the display effect obtained by using the method provided by the present invention The driving method of the display panel enables the display panel to have better display effect. Moreover, since the data line 10 in the embodiment of the present invention scans a column of pixel units 20, the polarity of the data line driving signal only changes once, compared with the data line driving signal corresponding to each data line 10 in the prior art, it needs The polarity is inverted multiple times. In the embodiment of the present invention, the number of polarity inversions of the data line driving signal corresponding to each data line 10 is significantly reduced, thereby reducing power consumption for driving the display panel.

It should be noted that, the driving method of the above-mentioned display panel may also be that in the same frame, after each data line 10 sequentially scans part of the first pixel unit groups 21 in the corresponding column, the driving signal of the data line 10 is performed once. The polarity is reversed, and then the part of the second pixel unit group 22 in the corresponding column is scanned sequentially, and then the data line driving signal is subjected to a polarity reversal again, and then, the above steps are repeated until the data line 10 converts a column of pixel units 20 scanning is completed, and the polarities of the initial data line driving signals of two adjacent data lines 10 are opposite; the polarities of the initial data line driving signals of two adjacent frames of pictures are opposite. Wherein, the number of the first pixel unit group 21 in the above-mentioned part of the first pixel unit group 21 and the number of the second pixel unit group 22 in the part of the second pixel unit group 22 can be set according to the actual situation, and it is only necessary to make each data line The number of inversions of the data line driving signal corresponding to 10 is less than the number of inversions of the data line driving signal corresponding to each data line 10 in the prior art. Exemplarily, as shown in FIG. 3 and FIG. 6, the above-mentioned part of the first pixel unit group 21 includes two first pixel unit groups 21, and part of the second pixel unit group 22 includes two second pixel unit groups 22, then in In the same frame, after each data line 10 scans the two first pixel unit groups 21 in the corresponding column in sequence, the driving signal of the data line 10 performs a polarity inversion, and then scans the two first pixel unit groups 21 in the corresponding column in sequence. The second pixel unit group 22, after that, the polarity of the data line driving signal is reversed again, and then, the above steps are repeated until the data line 10 scans a column of pixel units 20. At this time, each data line 10 corresponds to The number of inversions of the data line driving signal is smaller than that of the data line driving signal corresponding to each data line 10 in the prior art. However, in FIG. 6, +V represents positive polarity, and -V represents negative polarity.

It should also be noted that there is a Z inversion driving method in the prior art, that is, the pixel units scanned by each data line are located on both sides of the corresponding data line, and after the data line scans a pixel unit located on one side, it scans a pixel unit located on the other side. For the pixel unit on the other side, repeat the above steps until the data line scans the pixel units connected to it. In the Z inversion driving mode, in order to drive all the pixel units in the display panel, data lines are provided on both sides of a column of pixel units at the edge of the display panel, and in the embodiment of the present invention, as shown in Figure 3 As shown, in the pixel units located at the edge of the display panel, only one column of pixel units 20 is provided with data lines 10 on both sides, and the other column of pixel units 20 has no data lines 10 on one side. Therefore, compared with the Z inversion driving method , the driving method provided by the embodiment of the present invention does not need to add an additional data line 10; and, in the Z inversion driving mode, the data line is electrically connected to the pixel units on the left and right sides, which is different from the prior art shown in Figure 1 The connection relationship between the common data line and the pixel unit is different, but in the embodiment of the present invention, the data line 10 is only electrically connected to the pixel unit 20 on one side, which is different from the common data line in the prior art as shown in FIG. 1 The connection relationship between the line and the pixel unit is the same, so compared with the connection relationship between the data line and the pixel unit in the Z inversion driving method, the driving method of the display panel provided by the embodiment of the present invention can be applied to the existing In a display panel common in the art, there is no need to change the connection relationship between the data line 10 and the pixel unit 20 .

In 8, +V represents positive polarity, and -V represents negative polarity. In FIG. 8, in the Nth frame, after the first data line 10 scans all the first pixel unit groups 21 sequentially, the data line driving signal undergoes a polarity inversion, and then scans all the second pixel units sequentially. Group 22, the polarity of the initial data line driving signal of the second data line 10 is opposite to that of the first data line 10; in the N+1th frame, the first data line 10 and the first The polarities of the initial data line driving signals for each data line 10 are reversed. It can be seen from the above that, compared with the number of polarity inversions of the data line driving signal corresponding to each data line 10 in the prior art, in the embodiment of the present invention, the polarity inversion of the data line driving signal corresponding to each data line 10 The number of revolutions is significantly reduced, thereby reducing the power consumption required to drive the display panel.

In the third situation, as shown in FIG. 9 , the first pixel unit group 21 includes two adjacent pixel units 20 , and the second pixel unit group 22 includes one pixel unit 20 . At this time, in the same frame, in each column of pixel units 20, the polarity of the pixel units 20 in the first pixel unit group 21 is opposite to that of the pixel units 20 in the second pixel unit group 22. The polarities of the two adjacent pixel units 20 are opposite; the polarities of the pixel units 20 in two adjacent frames are opposite. The polarity distribution of the unit 20, wherein, N is a positive integer greater than or equal to 1.
