Technical Field

The embodiment of the invention relates to the technical field of display, in particular to a display panel, a driving method and a display device.

Background

In recent years, liquid crystal display devices have been widely used in many fields, and continue to exhibit a rapidly increasing trend. In general, a liquid crystal display device is mainly composed of two glass substrates and an anisotropic liquid crystal layer between the two glass substrates, and each sub-pixel includes liquid crystal and a pixel electrode and a common electrode for driving the liquid crystal to deflect. The driving process of the liquid crystal panel is that the display signals of the sub-pixels are loaded on the pixel electrodes, the common voltage signals are loaded on the reference electrodes, so that an electric field is formed to control the deflection of the liquid crystal, the sub-pixels realize the driving and lighting, and the display panel realizes the scanning and the display of image signals macroscopically.

However, when the sub-pixels in the same row of the conventional liquid crystal panel are driven to display by scanning, when the sub-pixels in the same color are displayed in a local area, the polarities of the display signals input by the sub-pixels in the same color are the same, the common voltage signal is disturbed, so that the common signal is pulled up or pulled down as a whole, which affects the accurate display of other sub-pixels in the same row, for example, crosstalk (brightness change of the sub-pixels in the row direction) in the horizontal direction (row direction) is caused, and especially when the sub-pixels in two colors in the local area are displayed simultaneously, the crosstalk phenomenon is more serious, which results in a decrease in the display effect.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Fig. 1 is an equivalent circuit diagram of a circuit structure in a sub-pixel of a display panel in the prior art, and referring to fig. 1, a Data line (denoted by Data) is electrically connected with a pixel electrode (denoted by a black dot marked as P) through a transistor, and a capacitance between the pixel electrode P and a common electrode (denoted by Vcom) mainly comprises: the capacitance of the liquid crystal denoted by Clc and the storage capacitance denoted by Cst have a corresponding abrupt change in the signal of the pixel electrode P when the polarity of the display signal on the data line is abruptly changed, and affect the common signal on the common electrode when the voltage difference across the capacitances (Clc and Cst) is maintained. It can be understood that the display panel is composed of a plurality of rows and columns of sub-pixels arranged in sequence, and when the polarities of the display signals written by the sub-pixels of the same color lighted in the local area are the same, the influence is amplified, resulting in the pulling-up or pulling-down of the common signal. At this time, the lighted sub-pixels around the local area change the original display brightness due to the pulling up or pulling down of the common signal, which causes inaccurate display brightness and causes crosstalk in the horizontal direction of the display panel.

Fig. 2 is a schematic diagram of a pixel driving of a display panel according to an embodiment of the present invention, and referring to fig. 2, the display panel includes red, green and blue Bai Sichong color sub-pixels 10, and the sub-pixels are sequentially and periodically arranged in a row direction according to an order of the four colors. Meanwhile, eight sub-pixels 10 adjacent to each other in the same row of the display panel are connected to eight data lines 20 in a one-to-one correspondence manner to form a group, the output is controlled by two data buses 40 and two multiplexers 30 (the structure of two dashed boxes in the figure), each multiplexer 30 is connected to four data lines 20 in a correspondence manner, and each data line controls the multiplexer 30 to gate the data line 20 by a timing control signal CKH. Taking the first row as an example in the figure, which includes red, green, blue, white, red, green, blue, bai Bage sub-pixels, each sub-pixel 10 is provided with a positive polarity or positive polarity display signal Source, abbreviated as S + or S-. As shown in fig. 2, the sign "+" indicates that the sub-pixel inputs a display signal of positive polarity, and the sign "-" indicates that the sub-pixel inputs a display signal of negative polarity, respectively.

FIG. 3 is a timing diagram of a prior art timing control signal for the display panel shown in FIG. 2, and Table 1 is a table of control logic and polarity analysis for the first row of the display panel shown in FIG. 2, wherein P1-P8 represent eight sub-pixels in the first row of the display panel. The following describes a driving process of the prior art by taking the eight sub-pixels in the first row as an example. First, the two multiplexers 30 include eight switching elements T1-T8, which are controlled by the timing control signals CKH1-CKH8 respectively. As can be known from fig. 3, the timing control signals CKH1 and CKH5 synchronously turn on the corresponding switch elements T1 and T5, the timing control signals CKH2 and CKH6 synchronously turn on the corresponding switch elements T2 and T6, the timing control signals CKH3 and CKH7 synchronously turn on the corresponding switch elements T3 and T7, and the timing control signals CKH4 and CKH8 synchronously turn on the corresponding switch elements T4 and T8. As can be seen from table 1, when the timing control signals CKH1 and CKH5 are synchronously turned on, the red subpixel P1 and the green subpixel P2 in the first row are synchronously driven to light, and the polarities of the display signals are opposite; when the timing control signals CKH2 and CKH6 are synchronously started, the blue sub-pixel P3 and the white sub-pixel P4 positioned in the first row are synchronously driven and lightened, and the polarities of the display signals are opposite; when the timing control signals CKH3 and CKH7 are synchronously started, the green sub-pixel P6 and the red sub-pixel P5 which are positioned in the first row are synchronously driven and lightened, and the polarities of the display signals are opposite; when the timing control signals CKH4 and CKH8 are synchronously turned on, the white sub-pixel P8 and the blue sub-pixel P7 in the first row are synchronously driven to light, and the polarities of the display signals are opposite.

However, although the pixel driving method described above realizes paired lighting in eight sub-pixels of a group and the polarities of the display signals of the two lighted sub-pixels are opposite, it is theoretically possible to achieve mutual cancellation of the polarities of the display signals, thereby avoiding the problem of crosstalk in the horizontal direction caused by the polarities of the sub-pixels in the same row being the same. However, since the colors of the two sub-pixels that are lit in pairs are different in the pixel driving process, it can be understood that, when the display panel displays only one color, that is, when only one color of the sub-pixels is lit, the sub-pixels of the other color that are paired with the sub-pixels are not lit by the driving method, and therefore, the polarities of the display signals cannot be cancelled out with the sub-pixels of the color, which also causes the problem of crosstalk. For example, when the middle region of the display panel needs to display red, and the corresponding red sub-pixel needs to be turned on, the timing control signal CKH1 and the timing control signal CKH7 sequentially turn on the switch elements T1 and T7, so as to turn on the red sub-pixels P1 and P5. Although the polarities of the display signals of the two red sub-pixels P1 and P5 are opposite, the polarities cannot be cancelled because they are not simultaneously turned on. The green sub-pixel P2 paired with the red sub-pixel P1 does not need to be driven to light at this time, and therefore cannot be offset in polarity with the red sub-pixel P1. The green subpixel P6 paired with the red subpixel P5 does not need to be driven to light at this time, and therefore cannot be offset in polarity from the red subpixel P5. In the edge area of the row, the horizontal crosstalk problem is caused by the positive polarity display signal of the red subpixel P1 and the negative polarity display signal of the red subpixel P5 sequentially received.

It should be noted that, the above-mentioned driving analysis is performed only on the eight sub-pixels grouped in the first row, and referring to the circuit structure and the driving timing shown in the figure, those skilled in the art can know that the same problems exist in the sub-pixels grouped in other rows, and the description thereof is omitted here.

In view of the above technical problem, embodiments of the present invention provide a display panel and a corresponding driving method, where the display panel includes a plurality of sub-pixels sequentially arranged along a row direction and a column direction, respectively; at least part of the sub-pixels in the same row have the same color, and at least part of the sub-pixels have different colors. For the display panel, the embodiment of the invention provides a corresponding driving method, that is, the display panel provided by the embodiment of the invention is driven by adopting the display panel driving method. The driving method includes: in any row of sub-pixels needing to be lightened, at least part of adjacent two sub-pixels with the same color are simultaneously input with display signals, and the polarities of the input display signals are different.

The above is the core idea of the display panel and the driving method provided by the present invention, and the technical solution in the above embodiment will be clearly and completely described below with reference to the drawings in the embodiment of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.

Fig. 4 is a schematic structural diagram of a display panel according to an embodiment of the present invention, and referring to fig. 4, the display panel includes a plurality of sub-pixels 10 sequentially arranged along a row direction and a column direction, respectively; at least some of the sub-pixels 10 in the same row have the same color, and at least some of the sub-pixels 10 have different colors; in any row of sub-pixels 10 that need to be lit, two adjacent sub-pixels 10 of the same color are simultaneously input with display signals, and the polarities of the input display signals are different. FIG. 5 is a timing diagram of timing control signals of the display panel shown in FIG. 4, and Table 2 is a table of control logic and polarity analysis for the first row of the display panel shown in FIG. 4, wherein P1-P8 represent eight sub-pixels of the first row of the display panel. Referring to fig. 4, fig. 5 and table 2, specifically, taking the first row of sub-pixels of the display panel as an example, the timing control signal CKH1 controls the switching elements T1 and T5 to be turned on or off simultaneously, and the positive polarity display signal S + and the negative polarity display signal S-are synchronously inputted to the red sub-pixels P1 and P5, respectively; the timing control signal CKH2 controls the switching elements T2 and T6 to be switched on or switched off simultaneously, and the negative polarity display signal S2-and the positive polarity display signal S2+ are synchronously and respectively input to the green sub-pixels P2 and P6; the timing control signal CKH3 controls the switching elements T3 and T7 to be turned on or off simultaneously, and the positive polarity display signal S3+ and the negative polarity display signal S3-are synchronously input to the blue sub-pixels P3 and P7, respectively; the timing control signal CKH4 controls the switching elements T4 and T8 to be turned on or off simultaneously, and the negative polarity display signal S4-and the positive polarity display signal S4+ are synchronously inputted to the white sub-pixels P4 and P8, respectively.

Obviously, the driving scheme realizes that the display signals with opposite polarities are synchronously input to two adjacent sub-pixels with the same color, and the display signals with opposite polarities of the two sub-pixels with the same color can effectively counteract the influence on the common voltage signal, so that the problem of crosstalk in the horizontal direction of the display panel is effectively solved. Moreover, it can be understood that no matter what color of picture is displayed by the display panel, such as a single red picture, a single green picture, a single blue picture or a red-green harmonic picture, a red-blue harmonic picture and a green-blue harmonic picture, the sub-pixel of each color can realize the cancellation of the display signal polarity of the sub-pixel of the same color adjacent to the sub-pixel of the same color, so that the problem of the crosstalk in the row direction caused by the same polarity of the display signal of the sub-pixel can be avoided.

It is to be understood that, in order to illustrate the principle of the display panel driving according to the embodiment of the present invention, the display panel and the driving scheme shown in fig. 4 and 5 are relatively simple, and in an application scenario of an actual display panel, a sub-pixel arrangement scheme, a driving circuit scheme, and the like of the display panel need to be designed based on different considerations.

In the display panel provided in the embodiment of the present invention, the plurality of sub-pixels located in the same row may be selected, the sub-pixels of at least one color are divided into two groups of sub-pixels, polarities of display signals input by the sub-pixels in the two groups of sub-pixels are different, colors and numbers of the sub-pixels in the two groups of sub-pixels are the same, and the sub-pixels in the two groups of sub-pixels correspond to each other and simultaneously input the display signals.

Continuing with the example of the display panel structure shown in fig. 4, among the plurality of sub-pixels 10 located in the same row, the sub-pixels 10 of the same color are divided into two groups of sub-pixels, the polarities of the display signals input by the sub-pixels 10 in the two groups of sub-pixels are different, in the figure, different padding indicates that the sub-pixels 10 belong to different groups, in the same row, the two sub-pixels 10 of the same color are respectively provided with a positive display signal and a negative display signal by the data lines 20, which are indicated by "+" and "-". The sub-pixels 10 in the two groups of sub-pixels have the same color and number, and the sub-pixels 10 in the two groups of sub-pixels correspond to one another and simultaneously input display signals.

It can be understood that, since the two groups of sub-pixels are equal in number, a corresponding sub-pixel 10 with the same color is provided with a display signal with opposite polarity to the synchronous input of the corresponding sub-pixel 10 in any row, and the two sub-pixels 10 can achieve synchronous polarity cancellation in any display screen. For any row of the display panel, the display signals of the sub-pixels are offset pairwise, so that the problem of horizontal crosstalk caused by the same polarity of the display signals of the sub-pixels in the display panel is effectively solved.

In other embodiments of the present invention, there may be other types of pixel arrangement designs, such that the sub-pixels inputting the positive display signals and the sub-pixels inputting the negative display signals in the sub-pixels of the same color are not in one-to-one correspondence, that is, in the plurality of sub-pixels located in the same row, the sub-pixels of any color may be divided into two groups of sub-pixels, the polarities of the display signals input by the sub-pixels in the two groups of sub-pixels are different, and the colors of the sub-pixels in the two groups of sub-pixels are the same, but the numbers of the sub-pixels in the two groups of sub-pixels are not equal. For such a display panel, the embodiment of the invention also provides a corresponding driving method, which may specifically include setting a group of sub-pixels with a smaller number to correspond to a group of sub-pixels with a larger number, and simultaneously inputting display signals.

Fig. 6 is a schematic structural diagram of another display panel according to an embodiment of the present invention, and referring to fig. 6, in the display panel, among a plurality of sub-pixels 10 located in the same row, the sub-pixels 10 of any color can be divided into two groups of sub-pixels, polarities of display signals input by the sub-pixels 10 in the two groups of sub-pixels are different, and the colors of the sub-pixels 10 in the two groups of sub-pixels are the same, and the numbers of the sub-pixels are not equal. The sub-pixels 10 belonging to different groups are also indicated by different fills respectively, and the sub-pixels 10 of different groups are provided with positive polarity display signals and negative polarity display signals respectively by the data lines 20, which are indicated by "+" and "-" respectively.

FIG. 7 is a timing diagram of timing control signals of the display panel shown in FIG. 6, and Table 3 is a table of control logic and polarity analysis for the first row of the display panel shown in FIG. 6, wherein P1-P12 represent twelve sub-pixels of the first row of the display panel. Referring to fig. 6, 7 and table 3, taking the red sub-pixel as an example, for the three red sub-pixels P1, P5 and P9 of the first row, they all control the synchronous input display signal by CKH 1. Whereas P1 and P9 belong to the same group and P5 belongs to the other group. At this time, by inputting the positive polarity display signal to P1 and P9 and synchronously inputting the negative polarity display signal to P5, the polarity cancellation can be realized for one positive polarity red subpixel corresponding to the negative polarity red subpixel P5. As can be seen from table 3, the driving process of the other color sub-pixels in the row is similar, and is not repeated here. Therefore, for any row of the display panel, the display signals of some sub-pixels can be cancelled in pairs, and the number of sub-pixels with the same display polarity in the display panel can be effectively reduced, so that the problem of row direction crosstalk caused by the fact that a large number of sub-pixels have the same display signal polarity is solved.

It can be understood that the sub-pixels in the display panel are divided into a plurality of pixel driving minimum repeating units, and the data lines, the multiplexers and the data buses are configured corresponding to the pixel driving minimum repeating units, so that different pixel driving minimum repeating units can be ensured to be driven in the same driving mode. In addition, in this embodiment, the pixel driving minimum repeating unit is taken as a unit, the sub-pixels in the pixel driving minimum repeating unit are divided into at least two sub-pixel groups, the sub-pixels corresponding to the two sub-pixel groups are respectively provided with the display signals by the two data buses, and the polarities of the display signals provided by the two data buses are opposite, so that the data buses and the display signal transmission channels connected with any one of the sub-pixels can be controlled to be turned on at any time by the multiplexer, and the possibility of simultaneously providing the display signals with different polarities for the two adjacent sub-pixels with the same color is provided on a structural basis. In this embodiment, according to the pixel and driving circuit structure of the display panel, a corresponding driving timing sequence is designed, and the display signals input by the data bus are input to the sub-pixels in a time-sharing manner by using the multiplexer, so that the display signals are simultaneously input to at least some of the sub-pixels located in the same row and having the same color, and the polarities of the input display signals are different, thereby ensuring that the sub-pixels having the same color can simultaneously input display signals with opposite polarities, effectively canceling the influence on the common voltage signal, and effectively solving the problem of crosstalk in the horizontal direction of the display panel.

Taking the first row as an example, the control logic and polarity analysis are performed, and referring to fig. 8, fig. 9 and table 4, for any row of sub-pixels 10 of the minimum repetition unit 100 driven by any one pixel, the driving method includes:

s110, during a first time period t1, the first display signal S1 is input to the first color sub-pixel 11 (red sub-pixel P1) in the first sub-pixel group 111 through the first multiplexer 31 and the data line, and the second display signal S2 is input to the first color sub-pixel 11 (red sub-pixel P4) in the second sub-pixel group 112 through the second multiplexer 32 and the data line for green; the first display signal S1 is a display signal input by the first data bus 41 in the first time period t1, the second display signal S2 is a display signal input by the second data bus 42 in the first time period t1, and polarities of the first display signal S1 and the second display signal S2 are opposite.

The first display signal S1 is provided by the first data bus 41, the second display signal S2 is provided by the second data bus 42, the first display signal S1 is a positive display signal S +, and the second display signal S2 is a negative display signal S-. During the first period t1, the positive polarity display signal S + and the negative polarity display signal S-are synchronously inputted to the red subpixels P1 and P4, respectively, and at this time, the red subpixels P1 and P4 realize polarity cancellation.

in this step, the third display signal S3 is substantially inputted to the third color sub-pixel 13 (blue sub-pixel P3) in the first sub-pixel group 111 through the first multiplexer 31 and the second data line 22, and the fourth display signal S4 is substantially inputted to the third color sub-pixel 13 (blue sub-pixel P6) in the second sub-pixel group 112 through the second multiplexer 32 and the sixth data line 26.

This step is substantially a process of controlling the turn-on of the corresponding light emitting elements T2 and T6 synchronously by the timing control signals CKH2 and CKH 6. The third display signal S3 is provided by the first data bus 41, the fourth display signal S4 is provided by the second data bus 42, the third display signal S3 is a positive display signal S +, and the fourth display signal S4 is a negative display signal S-. During the second period t2, the positive polarity display signal S + and the negative polarity display signal S-are synchronously input to the blue subpixels P3 and P6, respectively, and at this time, the blue subpixels P3 and P6 realize polarity cancellation.

S130, during the third time period t3, the fifth display signal S5 is input to the second color sub-pixel 12 (green sub-pixel P5) in the first sub-pixel group 111 through the first multiplexer 31 and the data line, and the sixth display signal S6 is input to the second color sub-pixel 12 (green sub-pixel P2) in the second sub-pixel group 112 through the second multiplexer 32 and the data line; the fifth display signal S5 is a display signal input by the first data bus 41 in the third time period t3, the sixth display signal S6 is a display signal input by the second data bus 42 in the third time period t3, and the polarities of the fifth display signal S5 and the sixth display signal S6 are opposite.

This step is substantially a process of controlling the turn-on of the corresponding light emitting elements T3 and T4 synchronously by the timing control signals CKH3 and CKH 4. The fifth display signal S5 is provided by the first data bus 41, the sixth display signal S6 is provided by the second data bus 42, the fifth display signal S5 is a positive display signal S +, and the sixth display signal S6 is a negative display signal S-. During the third time period t3, the negative polarity display signal S-and the positive polarity display signal S1+ are synchronously input to the green sub-pixels P2 and P5, respectively, and at this time, the green sub-pixels P2 and P5 realize the polarity cancellation.

It should be noted that, as explained in the above embodiment, the first row example of the pixel driving minimum repeating unit is only used, and the same applies to the sub-pixels of other rows. In other words, the other row of sub-pixels can also achieve mutual polarity cancellation of the same color sub-pixels according to the timing control signal. The difference is that in the first row, two red sub-pixels are turned on synchronously and their polarities cancel each other in the first period, two blue sub-pixels are turned on synchronously and their polarities cancel each other in the second period, and two green sub-pixels are turned on synchronously and their polarities cancel each other in the third period. In the other rows, the two sub-pixels of the other color are turned on synchronously and the polarities thereof cancel each other out in the first period, the second period and the third period, respectively.

In summary, in the driving process of any row of sub-pixels in the minimum repeating unit of pixel driving, two sub-pixels with the same color are synchronously turned on, and the influence on the common voltage signal is effectively counteracted. For the whole display panel, each pixel driving minimum repeating unit is provided with the same driving circuit and is driven by the same driving time sequence, so that the polarity cancellation of two sub-pixels with the same color in each pixel driving minimum repeating unit can be realized, and the problem of crosstalk in the horizontal direction of the display panel is effectively solved.

It should be noted that, in the driving sequence shown in fig. 9, the first time period t1, the second time period t2, and the third time period t3 respectively correspond to steps S110, S120, and S130, and the first time period t1, the second time period t2, and the third time period t3 only represent three different time periods in the driving sequence, and the sequence of the time periods is not limited in the embodiment of the present invention. It can be understood that, taking the first time period t1 in fig. 9 as an example, it may be located between the second time period t2 and the third time period t3, or after the third time period t3, and in the first time period t1, the processes of synchronously turning on the sub-pixels of the same color or different colors and mutually cancelling the polarities remain unchanged. Similarly, the second time period t2 and the second time period t3 may also be adjusted in sequence, where the polarity cancellation condition of the sub-pixels is not changed, and will not be described herein again.

It will also be appreciated that the display panel has different color arrangements in each row of the pixel driving minimal repeating unit, and therefore, the color definition of the sub-pixels in each row is different.
