[ background of the invention ]
Three-dimensional (3D) display can make a picture stereoscopic and vivid, and provide viewers with a feeling of being personally on the scene, which is an inevitable trend of future image display, compared with Two-dimensional (2D) display. Polarized glasses type stereoscopic display is a mainstream technology in the field of current 3D display, however, when a 3D picture is viewed in this way, polarized glasses need to be worn, so that the viewing comfort of a user is not high. Therefore, the naked eye 3D technology comes along, but the current naked eye 3D technology still has the problems of high power consumption and the like.
[ summary of the invention ]
In view of this, embodiments of the present invention provide a driving method of a display panel and a display device, which can effectively reduce power consumption of the display panel.
In one aspect, an embodiment of the present invention provides a driving method for a display panel, where the display panel includes a plurality of display units arranged along a first direction, where each display unit includes a first-type pixel unit and a second-type pixel unit, where the first-type pixel unit includes a plurality of first-type pixel rows arranged along the first direction, and the second-type pixel unit includes a plurality of second-type pixel rows arranged along the first direction;
one driving cycle of the display panel includes a plurality of driving periods corresponding one-to-one to a plurality of the display units, the driving method including: in each driving period, the first-type pixel rows and the second-type pixel rows in the display unit corresponding to the driving period are charged, and the charging time of at least two first-type pixel rows and the charging time of at least two second-type pixel rows with the same color are adjacent.
In another aspect, an embodiment of the present invention provides a display device, including:
the display panel comprises a plurality of display units arranged along a first direction, wherein each display unit comprises a first type pixel unit and a second type pixel unit, the first type pixel unit comprises a plurality of first type pixel rows arranged along the first direction, and the second type pixel unit comprises a plurality of second type pixel rows arranged along the first direction;
in one display unit, at least two pixel rows of the first type and two pixel rows of the second type which have the same color are adjacent in charging time.
One of the above technical solutions has the following beneficial effects:
when the display panel performs left-eye and right-eye imaging, the left-eye image and the right-eye image have the same display content, and only a slight difference exists between the display voltages, so that for two first-type pixel rows and two second-type pixel rows with the same color in the same display unit, the difference of the light-emitting brightness of two sub-pixels in the same column in the two pixel rows is small. Therefore, when the charging time of at least two first-type pixel rows and two second-type pixel rows with the same color are adjacent, after the data line charges the sub-pixels in the first-type pixel rows by using a certain charging voltage, the sub-pixels in the other second-type pixel rows can be charged only by jumping to the other charging voltage with a smaller amplitude or without jumping, so that the voltage jumping frequency and the voltage jumping amplitude of the data line are reduced, and the total power consumption of the display panel during working is effectively reduced.

[ detailed description ] embodiments
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one type of association that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Before describing the technical solutions provided by the embodiments of the present invention, the embodiments of the present invention first describe the problems existing in the prior art.
A display panel in the related art includes a plurality of display units each including a left-eye pixel row and a right-eye pixel row. Illustratively, the display unit includes a left-eye red pixel line, a left-eye green pixel line, a left-eye blue pixel line, a right-eye red pixel line, a right-eye green pixel line, and a right-eye blue pixel line. The left-eye pixel lines are used for displaying a left-eye image, the right-eye pixel lines are used for displaying a right-eye image, and the left-eye image and the right-eye image have a displacement difference, namely a voltage difference, so that a stereoscopic 3D image can be formed after synthesis.
As shown in fig. 1, fig. 1 is a timing diagram of a related art, and one driving cycle of a display panel includes a plurality of driving periods T corresponding to a plurality of display units one to one. In one driving period T, the charging sequence of the Data lines Data to the pixel rows in the display unit is: left eye red pixel row (corresponding to a charging voltage of V)1R) And the left eye green pixel row (corresponding charging voltage is V)1G) Left eye blue pixel row (corresponding to charging voltage V)1B) And the red pixel row of the right eye (corresponding to the charging voltage V)2R) And a green pixel row for the right eye (corresponding to a charging voltage of V)2G) And a right eye blue pixel row (corresponding to a charging voltage of V)2B)。
The inventors have studied and found that, based on the above-described driving manner, two pixel rows adjacent to each other in an arbitrary charging time are pixel rows of different colors. It can be understood that, when the display panel performs left-eye and right-eye image formation, the luminance difference of the light emitted from the sub-pixels with different colors is large, and thus the difference of the charging voltages transmitted to the data lines is also large. If two adjacent pixel rows with different charging time are pixel rows with different colors, after the data line finishes charging the sub-pixels in one of the pixel rows with a certain charging voltage, it is necessary to jump to another charging voltage with a larger difference to charge the sub-pixels in the other pixel row.
Specifically, referring again to FIG. 1, the data lines utilize a higher charging voltage V1RAfter the sub-pixels in the red pixel row for the left eye are charged, the voltage needs to jump to a lower charging voltage V1GCharging the sub-pixels in the left eye green pixel row and then jumping to a lower charging voltage V1BCharging the sub-pixels in the left-eye blue pixel row and then jumping to a higher charging voltage V2RThe subpixels in the row of red pixels for the right eye are charged, …, and so on, until the right eye is chargedThe charging of the sub-pixels in the eye blue pixel row ends.
Therefore, based on the above charging mode, each pair of data lines needs to perform a large voltage jump when charging the next pixel row, and the high and low potential jumps of the signal have a large influence on power consumption, so that the power consumption of the display panel during operation is high due to the charging mode.
To this end, an embodiment of the present invention provides a driving method of a display panel, as shown in fig. 2, fig. 2 is a schematic structural diagram of a display panel to which the driving method is applied, the display panel 100 includes a plurality of display units 1 arranged along a first direction, and each display unit 1 includes a first type pixel unit 2 and a second type pixel unit 3. The first-class pixel unit 2 comprises a plurality of first-class pixel rows 4 arranged along a first direction, the first-class pixel rows 4 comprise a plurality of first-class sub-pixels 5 arranged along a second direction and having the same emergent light color, the second-class pixel unit 3 comprises a plurality of second-class pixel rows 6 arranged along the first direction, the second-class pixel rows 6 comprise a plurality of second-class sub-pixels 7 arranged along the second direction and having the same emergent light color, and the first direction is intersected with the second direction.
The first-type pixel lines 4 are left-eye pixel lines, and the second-type pixel lines 6 are right-eye pixel lines, or the first-type pixel lines 4 are right-eye pixel lines, and the second-type pixel lines 6 are left-eye pixel lines.
In a possible embodiment, the first type pixel unit 2 comprises at least two first type pixel rows 4 with different light emission colors, and the second type pixel unit 3 comprises at least two second type pixel rows 6 with different light emission colors. Illustratively, referring again to fig. 2, the first-type pixel cells 2 include a first-type red pixel row 4R for emitting red light, a first-type green pixel row 4G for emitting green light, and a first-type blue pixel row 4B for emitting blue light, and the second-type pixel cells 3 include a second-type red pixel row 6R for emitting red light, a second-type green pixel row 6G for emitting green light, and a second-type blue pixel row 6B for emitting blue light.
Based on the above structure, one driving cycle of the display panel 100 includes a plurality of driving periods, and the plurality of driving periods T correspond to the plurality of display units 1 one to one, and the driving method provided by the embodiment of the present invention includes: in each driving period T, the first-type pixel row 4 and the second-type pixel row 6 in the display unit 1 corresponding thereto are charged, and the charging times of at least two first-type pixel rows 4 and second-type pixel rows 6 of the same color are adjacent.
In a possible implementation manner, referring to fig. 2 and fig. 3, as shown in fig. 3, fig. 3 is a timing diagram corresponding to fig. 2, in a driving period T, a charging sequence of a pixel row in the display unit 1 by a Data line Data is as follows: red pixel row 4R of the first type (corresponding to a charging voltage V)1R) First green pixel row 4G (corresponding to a charging voltage V)1G) A first blue pixel row 4B (corresponding to a charging voltage V)1B) A second type of blue pixel row 6B (corresponding to a charging voltage V)2B) A second red pixel row 6R (corresponding to a charging voltage V)2R) And a second type of green pixel row 6G (corresponding to a charging voltage V)2G)。
When the display panel 100 performs left-eye and right-eye imaging, the left-eye image and the right-eye image have the same display content, and only a slight difference exists between the display voltages, so that for two first-type pixel rows 4 and two second-type pixel rows 6 with the same color in the same display unit 1, the difference of the luminance of the two sub-pixels in the same column in the two pixel rows is small. Therefore, when the charging time of at least two first-type pixel rows 4 and two second-type pixel rows 6 with the same color are adjacent, after the Data line Data finishes charging the sub-pixels in the first-type pixel row 4 by using a certain charging voltage, the sub-pixels in the other second-type pixel row 6 can be charged only by jumping to another charging voltage with a small amplitude or without jumping.
For example, referring again to fig. 1 in the prior art, the Data line Data utilizes a very low charging voltage V1BAfter the sub-pixels in the left-eye blue pixel row are charged, the charging voltage V needs to jump to a higher charging voltage2RThe sub-pixels in the right eye green pixel row are charged and the voltage jump amplitude is large. In the embodiment of the present invention, referring to fig. 3, the Data line Data is goodWith very low charging voltage V1BAfter the sub-pixels in the first blue pixel row 4B are charged, the same very low charge voltage V can be used with only a slight or no transition2BThe sub-pixels in the second type blue pixel row 6B are charged.
Therefore, by using the driving method provided by the embodiment of the present invention, when charging the pixel rows in the display unit 1, the charging time of at least two pixel rows of the first type 4 and the second type 6 with the same color are adjacent to each other, so that the voltage jump frequency and the voltage jump amplitude of the Data line Data can be reduced, and the total power consumption of the display panel 100 during operation can be effectively reduced.
In one embodiment, as shown in fig. 4 to 7, fig. 4 is another schematic structural diagram of the display panel 100 according to an embodiment of the present invention, fig. 5 is a timing diagram corresponding to fig. 4, fig. 6 is a schematic structural diagram of the display panel 100 according to another embodiment of the invention, fig. 7 is a timing diagram corresponding to fig. 6, the display panel 100 further includes a plurality of scan line groups 8, the plurality of scan line groups 8 are in one-to-one correspondence with the plurality of display units 1 (in fig. 4 and 6, the scan line group corresponding to the ith display unit is denoted by reference numeral 8_ i, i is a positive integer greater than or equal to 1), the scan line group 8 is connected to the plurality of first-type pixel rows 4 in the display unit 1 corresponding thereto through the plurality of first switches 9, and is connected to the plurality of second-type pixel rows 6 in the display unit 1 corresponding thereto through the plurality of second switches 10.
The display panel 100 further includes a clock line group 11, where the clock line group 11 includes a plurality of clock signal lines CK, the control electrodes of the first switches 9 corresponding to the first-type pixel rows 4 of the same color in the plurality of display units 1 are connected to the same clock signal line CK, and the control electrodes of the second switches 10 corresponding to the second-type pixel rows 6 of the same color in the plurality of display units 1 are connected to the same clock signal line CK.
Based on the above structure, in each driving period T, the scanning line group 8 outputs the first active level 12 for starting charging of the pixel rows, the plurality of clock signal lines CK output the second active level 13 for controlling the switches to be turned on in a time-sharing manner, the first switch 9 transmits the first active level 12 to the first-type pixel rows 4 connected thereto when turned on, the first-type pixel rows 4 are controlled to be charged, and the second switch 10 transmits the first active level 12 to the second-type pixel rows 6 connected thereto when turned on, and the second-type pixel rows 6 are controlled to be charged.
It should be noted that, based on the specific structure of the pixel circuit in the display panel 100, when the transistor for controlling the writing of the charging voltage in the pixel circuit is a p-type transistor, the first active level 12 is at a low level, and when the transistor for controlling the writing of the charging voltage in the pixel circuit is an n-type transistor, the first active level 12 is at a high level. The second active level 13 is low when the first switch 9 and the second switch 10 are p-type transistors, and the second active level 13 is high when the first switch 9 and the second switch 10 are n-type transistors.
Based on the above driving manner, the plurality of scan line groups 8 output the first active level 12 in a time-sharing manner, when a certain scan line group 8 outputs the first active level 12, the plurality of clock signal lines CK output the second active level 13 in a time-sharing manner, and control the first switch 9 and the second switch 10 connected thereto to be turned on in a time-sharing manner, so as to control the first active level 12 output by the scan line group 8 to be transmitted to the first type pixel row 4 through the turned-on first switch 9 or to be transmitted to the second type pixel row 6 through the turned-on second switch 10, thereby controlling the sub-pixels in the first type pixel row 4 or the second type pixel row 6 to write the charging voltage in a time-sharing manner.
This time sharing charge's drive mode has not only reduced the mutual crosstalk between the different pixel row, has improved the reliability of charging of first type pixel row 4 and second type pixel row 6 in display element 1, and a plurality of pixel rows only need be connected to same scanning line or same clock signal line moreover, have reduced the line quantity of walking that sets up in display panel 100, have reduced the wiring complexity.

Based on the above-described structure, referring again to fig. 5, in each driving period T, the first scan signal output line Gout1 outputs the first active level 12, the first clock signal line CK1 and the second clock signal line CK2 alternately outputs the second active level 13, the first-type pixel rows 4 and the second-type pixel rows 6 are controlled to be alternately charged, and the first-type pixel rows 4 and one of the second-type pixel rows 6 adjacent to the charging time thereof are the same color.
Taking the first active level 12 and the second active level 13 as high levels as an example, in one possible implementation, referring to fig. 5 again, one driving period T includes six periods. In the first period t1, the first clock signal line CK1R outputs a high level, the first switch 9 connected to the first red pixel row 4R is turned on, and the high level output by the first scan signal output line Gout1 controls the first red pixel row 4R to be charged on, so that the charging voltage V transmitted on the Data line Data is enabled4RWritten into the sub-pixels of the first red pixel row 4R.
In the second period t2, the second clock signal line CK2R outputs a high level, the second switch 10 connected to the second type red pixel row 6R is turned on, and the high level output by the first scan signal output line Gout1 controls the second type red pixel row 6R to be charged on, so that the charging voltage V transmitted on the Data line Data is6RWriting red pixels of the second typeRow 6R of subpixels.

In addition, it should be noted that, based on the above concept that the color of the first-type pixel row 4 and one of the second-type pixel rows 6 adjacent to the charging time thereof are the same, the embodiment of the present invention may also use other charging sequences to charge the pixel rows in the display unit 1.

As can be seen, in this embodiment, the order of charging the rows of pixels in the display unit 1 by the data lines is: a first type red pixel row 4R, a first type green pixel row 4G, a first type blue pixel row 4B, a second type blue pixel row 6B, a second type green pixel row 6G, and a second type red pixel row 6R. The charging times of the first type blue pixel rows 4B and the second type blue pixel rows 6B are adjacent.
Based on the above driving manner, on one hand, the light emitting colors of the first-type pixel row 4 charged last in the first sub-period T11 and the second-type pixel row 6 charged first in the second sub-period T12 are the same, and when the two pixel rows are charged, the data lines only need to perform slight voltage jump or do not need to perform jump, so that the total power consumption of the display panel 100 is reduced. On the other hand, the first pixel row 4 and the second pixel row 6 of the same color in the display panel 100 only need to be connected to the same third clock signal line CK3, so that the number of clock signal lines required in the display panel 100 is small, and the space occupied by the clock line group 11 in the display panel 100 is reduced.
In addition, it should be noted that, based on the above concept, the embodiment of the present invention may also use other charging sequences to charge the pixel rows in the display unit 1.
Illustratively, as shown in fig. 10, fig. 10 is another timing diagram corresponding to fig. 6, and in one driving period T, the sequence of charging the pixel rows in the display unit 1 by the data lines is as follows: a first type red pixel row 4R, a first type blue pixel row 4B, a first type green pixel row 4G, a second type green pixel row 6G, a second type blue pixel row 6B, and a second type red pixel row 6R.
Alternatively, as shown in fig. 11, fig. 11 is still another timing chart corresponding to fig. 6, in a driving period T, the sequence of charging the pixel rows in the display unit 1 by the data lines is: a first type blue pixel row 4B, a first type red pixel row 4R, a first type green pixel row 4G, a second type green pixel row 6G, a second type red pixel row 6R, and a second type blue pixel row 6B.
Further, in conjunction with fig. 7, 10 and 11, there is a second active level 13 corresponding to the first-type pixel row 4 and the second-type pixel row 6 which are adjacent in part of the charging time, which lasts from the charging of the first-type pixel row 4 to the charging of the second-type pixel row 6, or from the charging of the second-type pixel row 6 to the charging of the first-type pixel row 4.
For example, referring to fig. 7 again, in the driving period T, the second active level 13 corresponding to the first type blue pixel row 4B charged last in the first sub-period T11 and the second type blue pixel row 6B charged first in the second sub-period T12 lasts from the charging of the first type blue pixel row 4B to the charging of the second type blue pixel row 6B.
With this arrangement, when the third clock signal line CK3 controls the two first-type pixel rows 4 and the second-type pixel rows 6 to be charged, only the second active level 13 needs to be maintained, and the high and low levels do not need to jump, so that the voltage jump frequency on the third clock signal line CK3 is reduced, and the total power consumption of the display panel 100 is reduced to a greater extent.
In one embodiment, referring to fig. 5 and 7 again, one driving period T of two adjacent driving periods T is a first driving period T1, the other driving period T is a second driving period T2, and the first driving period T1 is earlier than the second driving period T2. The last charged pixel row in the first driving period T1 is a first pixel row, and the first charged pixel row in the second driving period T2 is a second pixel row, and the colors of the first pixel row and the second pixel row are the same.
For example, referring to fig. 5 again, taking the first driving period T1 and the second driving period T2 labeled in fig. 5 as an example, the first pixel row charged last in the first driving period T1 is the second kind of blue pixel row 6B, and the second pixel row charged first in the second driving period T2 is the second kind of blue pixel row 6B. Referring to fig. 7 again, taking the first driving period T1 and the second driving period T2 labeled in fig. 7 as an example, the first pixel row charged last in the first driving period T1 is the red pixel row of the second type 6R, and the second pixel row charged first in the second driving period T2 is the red pixel row of the first type 4R.
With this arrangement, in addition to making the colors of the first-type pixel row 4 and the second-type pixel row 6 adjacent to each other in at least two charging times in the single driving period T identical, the color of the last-charged pixel row in the first driving period T1 and the color of the first-charged pixel row in the second driving period T2 are also identical, and in the charging process, the charging times of the first-type pixel row 4 and the second-type pixel row 6 having the same color are made adjacent to each other as much as possible, so that the hopping frequency and the hopping width of the charging voltage on the data lines are reduced to a greater extent, and the total power consumption of the display panel 100 is reduced to a greater extent.
Further, referring to fig. 5 and 7 again, the second active level 13 corresponding to the first pixel row and the second pixel row continues from the beginning of charging the first pixel row to the end of charging the second pixel row, so that the voltage jump frequency on a portion of the third clock signal lines can be reduced, and the total power consumption of the display panel 100 can be further reduced.

The left-eye pixel lines are used for presenting a left-eye image, the right-eye pixel lines are used for presenting a right-eye image, and the left-eye image and the right-eye image have a displacement difference, so that a stereoscopic 3D image can be formed after synthesis.
In the embodiment of the present invention, by making the charging time of at least two first-type pixel rows 4 and second-type pixel rows 6 with the same color adjacent to each other, after the data line charges the sub-pixels in the first-type pixel row 4 with a certain charging voltage, the sub-pixels in the other second-type pixel row 6 can be charged only by jumping to another charging voltage with a small amplitude or without jumping, so that the voltage jump frequency and the voltage jump amplitude on the data line are effectively reduced, and the total power consumption of the display panel 100 is further effectively reduced.
