Description
Technical Field
The present invention relates to the field of display technologies, and in particular, to a display panel, a driving method thereof, and a display device.
Background
Liquid crystal displays, which are flat, ultra-thin display devices, consist of a certain number of color or black and white pixels placed in front of a light source or a reflective surface. Liquid crystal displays are very low power consuming and are therefore favored by engineers for use in battery-operated electronic devices. The main principle is that the current stimulates the liquid crystal molecules to generate points, lines and surfaces which are matched with the back lamp tube to form a picture.
In general, a liquid crystal display is provided with a plurality of sub-pixels, the sub-pixels forming sub-pixel rows and sub-pixel columns, each sub-pixel row including a plurality of pixel units, each pixel unit typically including a red sub-pixel, a green sub-pixel, and a blue sub-pixel. In the display process, pixel rows are generally scanned line by line, sub-pixels in the corresponding pixel rows receive data signals through data lines, and the colors of the sub-pixels corresponding to a plurality of data lines electrically connected with the same data signal terminal are different. Generally, in the same time frame, the polarities of the data signals received by two sub-pixels adjacent to each other in the row direction are opposite, and in a specific image display, for example, when a pure color image display is implemented, because in one pixel row, the data line corresponding to the same data signal terminal is connected to both the red sub-pixel and the blue and green sub-pixels, the data signal terminal needs to provide data to the red sub-pixel of 255, and when the blue sub-pixel or the green sub-pixel in the same row is scanned, the data signal terminal needs to provide data to the blue sub-pixel or the green sub-pixel of 0, and therefore, when the same pixel row is scanned, the data signal transmitted by the same data signal terminal needs to be inverted/hopped multiple times, which greatly increases the power consumption of the liquid crystal display and is not beneficial to saving the power consumption. Moreover, in a pure color display image, taking a red image as an example, the polarities of the data signals received by the red sub-pixels in the same pixel row are the same, and the polarities of the data signals received by the red sub-pixels in the odd-numbered rows and the even-numbered rows are opposite, so that when scanning line by line, a positive row and a negative row occur, and thus a cross talk problem occurs in the display panel, which affects normal display.

In addition, because the data signal end is arranged on the driving chip, the arrangement mode of the display panel driving circuit reduces the number of the data signal ends on the driving chip, and is beneficial to reducing the size of the driving chip, thereby reducing the occupied space of the driving chip on the display panel.
Moreover, when a pure color image is displayed, when a data signal is transmitted to a certain pixel row through the data signal terminal and the data signal line (i.e., when a certain pixel row is charged), since the color and polarity of the sub-pixels electrically connected to the data line corresponding to the same data signal terminal are the same in any pixel row, when a specific image is displayed, for example, when a pure color image is displayed, the data signal transmitted by the same data signal terminal is kept unchanged without jumping/flipping when any pixel row is scanned, which is beneficial to saving the power consumption of the display panel and the display device, and further beneficial to prolonging the service life of the display panel and the display device.
In addition, the odd-numbered pixel rows are sequentially scanned in the first drive period, and the even-numbered pixel rows are sequentially scanned in the second drive period. Because the color of the sub-pixels electrically connected with the data lines corresponding to the same data signal end is the same, and the polarity of the data signals sent by the same data signal end to the sub-pixels corresponding to the same data signal end is also the same, when the pure color picture display is carried out, the polarity of the data signals received by the sub-pixels in each odd row is the same in the first driving period, and the phenomenon that one row is positive and one row is negative is avoided; in the second driving period, the polarities of the data signals received by the sub-pixels in the even rows are also the same, and the phenomenon that one row is positive and one row is negative is also avoided. Therefore, in the application, the odd pixel rows and the even pixel rows are alternately driven, so that the problem of crosstalk (crosstalk) of the display panel is solved, and the display stability is favorably improved.

Detailed Description
Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Referring to fig. 1 and 2, fig. 1 is a schematic diagram illustrating a connection of sub-pixels in a liquid crystal display device according to the prior art, and fig. 2 is a schematic diagram illustrating a display of the liquid crystal display device in fig. 1 under a pure color frame.
Referring to fig. 1, the data signal terminals S11, S12, S13 and S14 are electrically connected to three data lines, respectively, for example, the data signal terminal S11 is electrically connected to the data lines D1, D2 and D3, for the first pixel row, D1 is electrically connected to the red sub-pixel R, D2 is electrically connected to the blue sub-pixel B, and D3 is electrically connected to the green sub-pixel G. When the pure color image display is required, for example, when the blue image display is performed, when the first pixel row is scanned, the data signal terminal S11 transmits data signals to the data lines D1, D2 and D3 in a time division manner, and the data signal terminal S11 transmits data 0 to the red subpixel R through the data line D1, transmits data 255 to the blue subpixel B through the data line D2, and transmits data 0 to the green subpixel G through the data line D3. It can be seen that, during the scanning of one pixel row, the data signal sent by the data signal terminal S11 has jumped or flipped 2 times, from 0 to 255, and then from 255 to 0. Therefore, the power consumption of the liquid crystal display is greatly improved, and the power consumption is not saved.
Referring to fig. 2, when displaying a pure color image, taking a red sub-pixel as an example, the red sub-pixel in the display device is turned on. When the display is performed line by line, the polarity of the data signal received by the red sub-pixel of the odd pixel line is positive, and the polarity of the data signal received by the red sub-pixel of the even pixel line is negative, that is, a positive line and a negative line appear in the display device, so that the cross talk problem of the display panel occurs, and the normal display is affected.
In view of the above, the present invention provides a display panel, a driving method thereof and a display device, wherein the color and polarity of the sub-pixels electrically connected to the data lines corresponding to the same data signal terminal are the same, which greatly reduces the power consumption of the display panel and the display device; meanwhile, each line scanning mode is beneficial to avoiding the situation that one line is positive and one line is negative, solving the cross talk problem of the display panel and being beneficial to improving the display stability.
Fig. 3 is a top view of the display panel according to the embodiment of the present disclosure, and fig. 4 is a schematic connection diagram of sub-pixels in the display panel according to the embodiment of the present disclosure.
Referring to fig. 3 and fig. 4, the present application provides a display panel 100, including:
a plurality of pixel rows 10 and a plurality of pixel columns 20, each sub-pixel 30 in a pixel row 10 being arranged along a first direction, each sub-pixel 30 in a pixel column 20 being arranged along a second direction, the first direction and the second direction intersecting;
a plurality of data lines 40 extending along the second direction and arranged along the first direction, wherein the same data line 40 is electrically connected with at least some sub-pixels 30 in two adjacent pixel columns 20 respectively;
a plurality of switch units 50, wherein the first poles of the switch units 50 are respectively and correspondingly electrically connected with the N data lines 40, wherein N is more than or equal to 3;
a plurality of data signal terminals S1/S2/S3/S4 arranged in a first direction, one data signal terminal being electrically connected to a second pole of one switching cell 50; in the same pixel row 10, the sub-pixels 30 electrically connected to the data lines 40 corresponding to the same data signal terminal have the same color;
a plurality of switch control lines K to which control ends of the plurality of switch units 50 corresponding to the same data signal end are connected, respectively;
in the same time frame, the polarities of the data signals transmitted by the same data signal terminal to the sub-pixels 30 electrically connected to the corresponding data lines 40 are the same; the same time frame comprises a first driving period and a second driving period, in the first driving period, the odd-numbered pixel rows are scanned sequentially, in the second driving period, the even-numbered pixel rows are scanned sequentially, the first driving period and the second driving period are adjacent, and in the first driving period, the polarities of the data signals received by the sub-pixels 30 of the odd-numbered rows which are adjacent randomly along the first direction are the same; in the second driving period, the polarities of the data signals received by the sub-pixels of the even-numbered rows which are arbitrarily adjacent to each other along the first direction are the same.
It should be noted that fig. 3 only shows the case where the display panel 100 includes a plurality of sub-pixels 30, and does not represent the actual size and number of sub-pixels 30 included in the display panel 100. Fig. 4 also only shows the connection relationship of a part of the sub-pixels 30 in the display panel 100, and does not represent that only this part of the sub-pixels 30 is included in the display panel 100, and the connection relationship of the sub-pixels 30 not shown can refer to the embodiment shown in fig. 4.
Specifically, with continued reference to fig. 3 and fig. 4, in the display panel 100 provided by the present application, a plurality of data lines 40 extend along the second direction and are arranged along the first direction, the same data line 40 is electrically connected to at least some of the sub-pixels 30 in two adjacent pixel columns 20, that is, the same data line 40 is shared by the adjacent odd-numbered pixel columns 20 and even-numbered pixel columns 20, the data line 40 is electrically connected to some of the sub-pixels 30 in the odd-numbered pixel columns 20 and is electrically connected to some of the sub-pixels 30 in the even-numbered pixel columns 20, and the sub-pixels 30 electrically connected to the same data line 40 are located in different pixel rows 10. Compared with the prior art in which one data line 40 corresponds to one data signal terminal, the present application introduces at least 2/3 of data signal terminals, so that the number of signal lines led out from the data signal terminals is reduced by half, thereby being beneficial to implementing a narrow-frame design of the display panel 100. In addition, since the data signal terminals are disposed on the driving chip, the number of the data signal terminals on the driving chip is reduced by the arrangement method of the present application, which is beneficial to reducing the size of the driving chip, thereby reducing the space occupied by the driving chip on the display panel 100.
In the case of a solid-color screen display, when a data signal is transmitted to a certain pixel row 10 through the data signal terminal and the data signal line (i.e., when the certain pixel row 10 is charged), for example, control signals are transmitted to the switch control lines K1, K2, K3, and K4 in a time-sharing manner, the switch cell 50 corresponding to the switch control line K1 is first turned on, and the data signal terminal S1 transmits the data signal to the sub-pixel 30 electrically connected to the data lines 41/42/43 in the first pixel row 10 through the data line 41; next, the switching unit 50 corresponding to the switching control line K2 is turned on, and the data signal terminal S2 transmits the data signal to the sub-pixels 30 electrically connected to the data lines 40 in the first pixel row 10 through the data lines 40 corresponding thereto; then, the switching unit 50 corresponding to the switching control line K3 is turned on, and the data signal terminal S3 transmits the data signal to the sub-pixels 30 electrically connected to the data lines 40 in the first pixel row 10 through the data lines 40 corresponding thereto; finally, the switching unit 50 corresponding to the switching control line K4 is turned on, and the data signal terminal S4 transmits the data signal to the sub-pixels 30 electrically connected to the data lines 40 in the first pixel row 10 through the data lines 40 corresponding thereto. In any pixel row 10, the color and polarity of the sub-pixels 30 electrically connected to the data lines 40 corresponding to the same data signal terminal (e.g., the data lines 41, 42, and 43 corresponding to the data signal terminal S1) are the same, so that when a specific image is displayed, for example, when a pure color image is displayed, the polarity of the data signal transmitted by the same data signal terminal is the same when any pixel row 10 is scanned, and the data signal does not need to jump/turn, which is beneficial to saving the power consumption of the display panel 100 and further beneficial to prolonging the service life of the display panel 100. It should be noted that, the polarity of the sub-pixel 30 mentioned in the present application refers to the polarity of the data signal received by the sub-pixel 30.
It should be noted that, in the embodiment shown in fig. 4, the switch control line electrically connected to the switch unit corresponding to the data signal terminal S5 may be the same as K1, or may be separately provided; similarly, the switch control line electrically connected to the switch unit corresponding to the data signal terminal S6 may be the same as K2, or may be separately provided; the switch control line electrically connected to the switch unit corresponding to the data signal terminal S7 may be the same as K3, or may be separately provided; the switch control line electrically connected to the switch cell corresponding to the data signal terminal S8 may be the same as K4, or may be provided separately. The switch control lines in the present application are also respectively connected to the driving chips in the display panel, and the driving chips send the switch control signals.
In addition, the odd-numbered pixel rows are sequentially scanned in the first drive period, and the even-numbered pixel rows are sequentially scanned in the second drive period. Since the color of the sub-pixels 30 electrically connected to the data lines 40 corresponding to the same data signal terminal is the same, and the polarity of the data signal transmitted from the same data signal terminal to the sub-pixels 30 corresponding thereto is also the same, when performing pure color image display, for example, red image display, the polarity of the data signal received by the sub-pixels 30 in each odd-numbered row is the same in the first driving period, for example, the polarity of the data signal received by the sub-pixels 30 in red in each odd-numbered row in fig. 5 is positive, so as to avoid the phenomenon of one row being positive and one row being negative, where fig. 5 is a first polarity distribution diagram of the data signal transmitted to the sub-pixels 30 in the first driving period under pure color image display. In the second driving period, the polarities of the data signals received by the sub-pixels 30 in the even rows are the same, for example, the polarities of the data signals received by the sub-pixels 30 in the red color in the even row in fig. 6 are all negative, so as to avoid the phenomenon of one row being positive and one row being negative, and fig. 6 is a first polarity distribution diagram of the data signals sent to the sub-pixels 30 in the second driving period under the pure color image display. Therefore, in the present application, the odd pixel rows and the even pixel rows are alternately driven, so that a crosstalk problem occurring in the display panel 100 is solved, and the display stability is improved. Fig. 5 and 6 show the polarity distribution diagrams in the pure color picture, and the sub-pixel corresponding to the dashed frame represents that the sub-pixel is not displayed.
Fig. 4 shows a case where N is 3, that is, each data signal terminal (corresponding to S1, S2, S3, S4, S5, S6, S7, and S8 in the figure) corresponds to 3 data lines 40, and 4 data signal terminals correspond to 12 pixel columns 20 to transmit data signals. Compared with the mode that one data signal end corresponds to one data line 40 in the prior art, the number of the data signal ends in the application is only 1/3 of the number of the data signal ends in the prior art, so that the number of the data signal ends is greatly reduced, the narrow-frame design is more favorably realized, and the size of a driving chip is reduced. It should be noted that in some other embodiments of the present application, N may also be embodied in other numbers that are greater than or equal to 3, which is not specifically limited in the present application. For example, referring to fig. 7, fig. 7 is a diagram illustrating another connection relationship of sub-pixels 30 in a display panel 100 according to an embodiment of the present disclosure, in which one data signal terminal corresponds to 4 data lines 40, and 4 data signal terminals correspond to control data signals sent to 16 pixel rows 20, which is also beneficial to implement a narrow frame design and reduce the size of a driver chip.
In an alternative embodiment of the present invention, fig. 8 is a connection relationship diagram of a data line 40 and a sub-pixel 30 in a display panel 100 provided in an embodiment of the present application, and in an nth pixel column 20 and an n +1 th pixel column 20 corresponding to the same data line 40: the same data line 40 is electrically connected to the odd-numbered sub-pixel 30 in the nth pixel column 20 and electrically connected to the even-numbered sub-pixel 30 in the (n + 1) th pixel column 20; or, the same data line 40 is electrically connected to the even sub-pixel 30 in the nth pixel column 20 and is electrically connected to the odd sub-pixel 30 in the (n + 1) th pixel column 20; wherein n is more than or equal to 1.

In an alternative embodiment of the invention, referring to fig. 11, fig. 11 is a diagram illustrating another connection relationship of sub-pixels 30 in the display panel 100 according to the embodiment of the present application, in which each of the switch units 50 electrically connected to the same switch control line is a P-type transistor or an N-type transistor.
Specifically, fig. 11 shows a case where the switch units 50 electrically connected to the same switch control line are P-type transistors, and in some other embodiments of the present application, the switch units electrically connected to the same switch control line may also be all N-type transistors, which is not specifically limited in the present application. The types of the transistors in the switch units 50 electrically connected with the same switch control line are set to be the same, and when the switch control line sends control signals to the transistors connected with the switch control line, the transistors electrically connected with the switch control line can be ensured to be simultaneously switched on or switched off, so that the unified control of the transistors connected with the switch control line is realized, and the control time sequence of the switch units 50 in the application is favorably simplified.
In an alternative embodiment of the present invention, each of the switch units 50 is a P-type transistor or an N-type transistor.
Specifically, when each switch unit 50 in the display panel 100 is configured as a P-type transistor or an N-type transistor, the types of the transistors in the switch units 50 electrically connected to each switch control line are all the same, and this configuration, on one hand, enables each transistor as the switch unit 50 to be manufactured uniformly in the same manufacturing process without separately configuring different manufacturing processes for different types of transistors, which is beneficial to simplifying the manufacturing process of the display panel 100; on the other hand, when the types of transistors included in the switch units 50 are the same, the control signals for controlling the switch units 50 to be turned on are the same, which is beneficial to simplifying the complexity of the logic processing process of the display panel 100, thereby being beneficial to improving the signal processing capability of the display panel 100.
Based on the same inventive concept, the present application further provides a driving method of the display panel 100 in any of the above embodiments of the present application, wherein the same time frame includes a first driving period and a second driving period, and the first driving period and the second driving period are adjacent to each other, please refer to fig. 12 in conjunction with fig. 4 and fig. 7, where fig. 12 is a flowchart of the driving method of the display panel 100 provided in the embodiment of the present application, and the driving method includes:
102, in a second driving period, scanning the even-numbered pixel rows in sequence, and when scanning a certain even-numbered pixel row, sending a control signal to each switch control line in a time-sharing manner to enable the switch units 50 electrically connected with different switch control lines to be switched on in a time-sharing manner; the data signal terminal transmits a data signal to the sub-pixel 30 in the even-numbered row electrically connected to the turned-on switching unit 50 through the turned-on switching unit 50; the polarities of the data signals received by the sub-pixels 30 of the even-numbered rows arbitrarily adjacent in the first direction are the same, and the colors of the sub-pixels 30 of the even-numbered rows arbitrarily adjacent in the first direction are the same.
It should be noted that, referring to fig. 4, when the odd-numbered pixel rows are scanned in the first driving period, each pixel row 10 may be scanned from top to bottom or each pixel row 10 may be scanned from bottom to top at the viewing angle shown in fig. 4. Similarly, during the second driving period, when the even-numbered pixel rows are scanned, the pixel rows 10 may be scanned from top to bottom or the pixel rows 10 may be scanned from bottom to top under the viewing angle shown in fig. 4.
In the following description, taking the scanning of one pixel row 10 as an example, assuming that when the first pixel row 10 is scanned, the control signal is sent to the switch control line in a time-sharing manner, the control signal is sent to the switch control lines K1, K2, K3 and K4 in a time-sharing manner, the switch unit 50 corresponding to the switch control line K1 is turned on first, and the data signal terminal S1 sends the data signal to the sub-pixels 30 electrically connected to the data lines 41/42/43 in the first pixel row 10 through the data lines 41; next, the switching unit 50 corresponding to the switching control line K2 is turned on, and the data signal terminal S2 transmits the data signal to the sub-pixels 30 electrically connected to the data lines 40 in the first pixel row 10 through the data lines 40 corresponding thereto; then, the switching unit 50 corresponding to the switching control line K3 is turned on, and the data signal terminal S3 transmits the data signal to the sub-pixels 30 electrically connected to the data lines 40 in the first pixel row 10 through the data lines 40 corresponding thereto; finally, the switching unit 50 corresponding to the switching control line K4 is turned on, and the data signal terminal S4 transmits the data signal to the sub-pixels 30 electrically connected to the data lines 40 in the first pixel row 10 through the data lines 40 corresponding thereto. In this way, each sub-pixel 30 in the first pixel row 10 receives the data signal, and the data signal writing of the first pixel row 10 is completed. In any pixel row 10, the color and polarity of the sub-pixels 30 electrically connected to the data lines 40 corresponding to the same data signal terminal (e.g., the data lines 41, 42, and 43 corresponding to the data signal terminal S1) are the same, so that when a specific image is displayed, for example, when a pure color image is displayed, the polarity of the data signal transmitted by the same data signal terminal is the same when any pixel row 10 is scanned, and the data signal does not need to jump/turn, which is beneficial to saving the power consumption of the display panel 100 and further beneficial to prolonging the service life of the display panel 100. It should be noted that, although not mentioned in S5-S8, when the first pixel row is used, S5-S8 also send data signals to the corresponding sub-pixels, respectively, as shown in S1-S4, which is not described herein again.
In the driving method, when each odd-numbered pixel row is scanned in the first driving period, because the color of the sub-pixels 30 electrically connected with the data lines 40 corresponding to the same data signal end is the same, and the polarity of the data signals sent by the same data signal end to the sub-pixels 30 corresponding to the same data signal end is also the same, when the pure color picture display is performed, the polarity of the data signals received by the sub-pixels 30 in each odd-numbered row is the same in the first driving period, so that the phenomenon that one row is positive and one row is negative is avoided; in the second driving period, the polarities of the data signals received by the even-numbered rows of sub-pixels 30 are also the same, so that the phenomenon that one row is positive and one row is negative is also avoided. Therefore, in the present application, the odd pixel rows and the even pixel rows are alternately driven, so that a crosstalk problem occurring in the display panel 100 is solved, and the display stability is improved.
In addition, the odd-numbered pixel rows are sequentially scanned in the first drive period, and the even-numbered pixel rows are sequentially scanned in the second drive period. Since the color of the sub-pixels 30 electrically connected to the data lines 40 corresponding to the same data signal terminal is the same, and the polarity of the data signal transmitted from the same data signal terminal to the sub-pixels 30 corresponding thereto is also the same, when performing pure color image display, for example, red image display, the polarity of the data signal received by the sub-pixels 30 in each odd-numbered row is the same in the first driving period, for example, the polarity of the data signal received by the sub-pixels 30 in red in each odd-numbered row in fig. 5 is positive, so as to avoid the phenomenon of one row being positive and one row being negative, where fig. 5 is a first polarity distribution diagram of the data signal transmitted to the sub-pixels 30 in the first driving period under pure color image display. In the second driving period, the polarities of the data signals received by the sub-pixels 30 in the even rows are the same, for example, the polarities of the data signals received by the sub-pixels 30 in the red color in the even row in fig. 6 are all negative, so as to avoid the phenomenon of one row being positive and one row being negative, and fig. 6 is a first polarity distribution diagram of the data signals sent to the sub-pixels 30 in the second driving period under the pure color image display. Therefore, in the present application, the odd pixel rows and the even pixel rows are alternately driven, so that a crosstalk problem occurring in the display panel 100 is solved, and the display stability is improved.
In an optional embodiment of the present invention, in the first driving period corresponding to the same time frame, the polarity of the data signal transmitted by the same data signal terminal is kept the same; in the second driving period corresponding to the same time frame, the polarity of the data signal transmitted by the same data signal terminal is kept the same.
Specifically, the time frame referred to in the present application refers to the time required to complete one scan for all the pixel rows 10 on the display panel 100. In the first driving period corresponding to the same time frame, that is, in the process of completing scanning on all the odd-numbered pixel rows, the polarities of the data signals sent by the same data signal terminal are kept the same, and in the first driving period, the polarities of the data signals sent by each data signal terminal do not need to be inverted, so that the power consumption of the display panel 100 is more favorably reduced, and the service life of the display panel 100 is prolonged. Similarly, in the second driving period corresponding to the same time frame, that is, in the process of completing scanning on all the even-numbered pixel rows, the polarity of the data signal sent by the same data signal terminal is kept the same, and in the second driving period, the polarity of the data signal sent by each data signal terminal does not need to be inverted, so that the power consumption of the display panel 100 is also reduced, and the service life of the display panel 100 is prolonged. Further, referring to fig. 4, in two adjacent pixel columns 20, the sub-pixels 30 electrically connected to the same data signal line are alternated one by one, so that, in the pure color image display, in the first driving period and the second driving period corresponding to any time frame, the polarities of the data signals sent by each data signal terminal are the same, and in the time frame, during the process of converting from the first driving period to the second driving period or during the process of converting from the second driving period to the first driving period, the polarities of the data signals sent by each data signal terminal do not need to be inverted, so that the power consumption of the display panel 100 can be greatly saved, which is beneficial to improving the standby time and the service life of the display panel 100.
In an alternative embodiment of the invention, within the same time frame: executing a first driving period and then executing a second driving period; or, the second driving period is executed first, and then the first driving period is executed. That is, in the same time frame, the odd-numbered pixel row may be scanned first and then the even-numbered pixel row may be scanned, or the even-numbered pixel row may be scanned first and then the odd-numbered pixel row may be scanned, which is not specifically limited in this application.

It should be noted that, for the embodiments of the display device 200 provided in the embodiments of the present application, reference may be made to the embodiments of the display panel 100, and repeated descriptions are omitted. The display device 200 provided by the present application may be: any product or component with practical functions such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator and the like.
In summary, the display panel, the driving method thereof and the display device provided by the invention at least achieve the following beneficial effects:
in the display panel, the driving method thereof and the display device provided by the application, a plurality of data lines extend along a second direction and are arranged along a first direction, the same data line is respectively and electrically connected with at least part of sub-pixels in two adjacent pixel columns, that is, the adjacent odd pixel column and the even pixel column share the same data line, the data line is electrically connected with part of sub-pixels in the odd pixel column and is simultaneously electrically connected with part of sub-pixels in the even pixel column, and the sub-pixels electrically connected with the same data line are respectively positioned in different pixel rows. This application has introduced a plurality of switch unit and a plurality of data signal end, and each switch unit's first utmost point is connected with data line one-to-one electricity respectively, and especially, a data signal end corresponds N at least data lines, compares the mode that a data line corresponds a data signal end among the prior art, and this application reduces 2/3 at least with the quantity of data signal end to make the quantity of the signal line of drawing forth from the data signal end halve, therefore be favorable to realizing display panel's narrow frame design. In addition, because the data signal end is arranged on the driving chip, the arrangement mode of the display panel driving circuit reduces the number of the data signal ends on the driving chip, and is beneficial to reducing the size of the driving chip, thereby reducing the occupied space of the driving chip on the display panel.
Moreover, when a pure color image is displayed, when a data signal is transmitted to a certain pixel row through the data signal terminal and the data signal line (i.e., when a certain pixel row is charged), since the color and polarity of the sub-pixels electrically connected to the data line corresponding to the same data signal terminal are the same in any pixel row, when a specific image is displayed, for example, when a pure color image is displayed, the data signal transmitted by the same data signal terminal is kept unchanged without jumping/flipping when any pixel row is scanned, which is beneficial to saving the power consumption of the display panel and the display device, and further beneficial to prolonging the service life of the display panel and the display device.
In addition, the odd-numbered pixel rows are sequentially scanned in the first drive period, and the even-numbered pixel rows are sequentially scanned in the second drive period. Because the color of the sub-pixels electrically connected with the data lines corresponding to the same data signal end is the same, and the polarity of the data signals sent by the same data signal end to the sub-pixels corresponding to the same data signal end is also the same, when the pure color picture display is carried out, the polarity of the data signals received by the sub-pixels in each odd row is the same in the first driving period, and the phenomenon that one row is positive and one row is negative is avoided; in the second driving period, the polarities of the data signals received by the sub-pixels in the even rows are also the same, and the phenomenon that one row is positive and one row is negative is also avoided. Therefore, in the application, the odd pixel rows and the even pixel rows are alternately driven, so that the problem of crosstalk (crosstalk) of the display panel is solved, and the display stability is favorably improved.
