For a further understanding of the driving method and driving device of above-mentioned display panel.It illustrates below in conjunction with the accompanying drawings.
Also referring to Fig. 1 to Fig. 2, wherein Fig. 1 is the flow of the driving method of the display panel of one embodiment of the invention Schematic diagram, the driving method are applied to display panel.As shown in Figure 1, the driving method 10 comprises the following steps：
Multiple pixel units of display panel are divided into several pixel unit groups, each pixel unit group bag by S101 Include the continuously arranged pixel unit of three rows.
Specifically, as shown in Fig. 2, display panel 20 has multiple pixel units in matrix distribution, the multiple pixel Unit includes several first pixel unit P1 and several second pixel unit P2, first pixel unit and second pixel Unit is disposed adjacent, and the first pixel unit is alternately arranged with the second pixel unit in other words.For example, as shown in Fig. 2, with the first picture The adjacent pixel unit of plain unit is the second pixel unit, and the pixel unit adjacent with the second pixel unit is the first pixel Unit.
Specifically, each pixel unit include multiple sub-pixels, such as each pixel unit include color it is different Multiple sub-pixels, for example, each pixel unit includes R (red) sub-pixel, G (green) sub-pixels and B (blueness) sub- picture respectively These three plain sub-pixels.Alternatively, each pixel unit includes R sub-pixels, G sub-pixel, B sub-pixels and W (white) sub- picture respectively These four plain sub-pixels.
S102 is adjacent to two rows in the continuously arranged pixel unit of three rows using the identical driving voltage of polarity Pixel unit is driven.
As a kind of embodiment, driving voltage is applied respectively to each sub-pixel in display panel so that same pixel In the continuously arranged pixel unit of three rows in unit group, the driving voltage polarity for the pixel unit for having two rows adjacent is identical.
For example, the continuously arranged pixel unit of three rows is according to respectively first position pixel unit, of putting in order Two position pixel units and the third place pixel unit, then a kind of embodiment of step S102 be, using the identical drive of polarity Dynamic voltage is driven the second position pixel unit and the third place pixel unit respectively.At this point, can be used with Pixel unit polarity opposite or identical driving voltage in the second position is driven the first position pixel unit, such as walks Rapid S102 is further included：Using opposite polarity driving voltage to the first position pixel unit and the second position pixel list Member is driven respectively.
Wherein, first position pixel unit, second position pixel unit and the third place pixel unit refer respectively to together The first row pixel unit, the second row pixel unit and the third line pixel being arranged in order in one pixel unit group according to certain order Unit.Such as certain order be by left-to-right order either by the right order to a left side or order from top to bottom or The order of person from down to up.
Wherein, the driving voltage polarity of different pixels unit is identical, refers to that position is corresponding in different pixels unit The driving voltage polarity of sub-pixel is identical.For example, when the R sub-pixels in the R sub-pixels in pixel unit C1 and pixel unit C2 Driving voltage polarity it is identical, and the driving voltage of the G sub-pixel in the G sub-pixel in pixel unit C1 and pixel unit C2 Polarity is identical, and the B sub-pixels in pixel unit C1 are identical with the driving voltage polarity of the B sub-pixels in pixel unit C2, And when the W sub-pixel in pixel unit C1 is identical with the driving voltage polarity of the W sub-pixel in pixel unit C2, pixel is represented Unit C1 is identical with the driving voltage polarity of pixel unit C2, and in same pixel unit, the driving voltage of different subpixel Polarity can be identical or opposite.
S103, using opposite polarity driving voltage to the first position sub-pixel and second in the same pixel unit Position sub-pixel is driven.
As a kind of embodiment, according to the position of sub-pixel, multiple sub-pixels in each pixel unit are divided into One position sub-pixel and second position sub-pixel.Wherein, first position and the second position are respectively centre position and marginal position. For example, first position sub-pixel is centre position sub-pixel, second position sub-pixel is marginal position sub-pixel；Alternatively, first Position sub-pixel is marginal position sub-pixel, and second position sub-pixel is centre position sub-pixel.
For another example, using first position sub-pixel as centre position sub-pixel, second position sub-pixel is marginal position sub-pixel Exemplified by, if pixel unit includes tactic R sub-pixels, G sub-pixel and B sub-pixels, first position sub-pixel includes G Pixel, second position sub-pixel include R sub-pixels and B sub-pixels.At this point, the is applied to the G sub-pixel in same pixel unit The driving voltage of one polarity applies the R sub-pixels in same pixel unit and B sub-pixels the driving voltage of the second polarity, makes It obtains in same pixel unit, the driving voltage polarity of centre position sub-pixel and marginal position sub-pixel is opposite.
If pixel unit includes tactic R sub-pixels, G sub-pixel, B sub-pixels and W sub-pixel, first position Pixel includes G sub-pixel and B sub-pixels, and second position sub-pixel includes R sub-pixels and W sub-pixel.At this point, to same pixel list G sub-pixel and B sub-pixels in member apply the driving voltage of the first polarity, to the R sub-pixels in same pixel unit and W pictures Element applies the driving voltage of the second polarity so that in same pixel unit, centre position sub-pixel and marginal position sub-pixel Driving voltage polarity it is opposite.
Wherein, the first polarity is positive polarity, and the second polarity is negative polarity；Alternatively, the first polarity is negative polarity, the second polarity For positive polarity.Positive polarity refers to that driving voltage is more than the default common-battery pole tension V of display panelcom, i.e. driving voltage and Vcom The pressure difference of voltage is more than zero；Negative polarity refers to that driving voltage is less than VcomVoltage, i.e. driving voltage and VcomThe pressure difference of voltage is small In zero.
S104, using the different driving voltage of voltage class respectively to the sub-pixel in the first pixel unit and the second pixel Sub-pixel in unit is driven.
As a kind of embodiment, apply the drive of default first voltage grade to the sub-pixel in first pixel unit Dynamic voltage；Apply the driving voltage of default second voltage grade to the sub-pixel in second pixel unit.
Specifically, the first pixel unit and the corresponding drive voltage level of the second pixel unit are pre-set, for example, Pre-set corresponding first drive voltage level of the first pixel unit and corresponding second driving voltage of the second pixel unit etc. Grade.Wherein, in the first drive voltage level and the second drive voltage level, one is voltage levels, another is low-voltage Grade.For example, the first drive voltage level is driven higher than the second drive voltage level or the first drive voltage level less than second Dynamic voltage class.
Wherein, voltage levels refer to, for the sub-pixel driven, the driving voltage of input is higher than the ash of the sub-pixel The corresponding preset voltage value of rank.Similarly, low-voltage-grade refers to, for the sub-pixel driven, the driving voltage of input is low In the corresponding preset voltage value of the grayscale of the sub-pixel.For example, in one sub-pixel of driven, to display 0~255 Grayscale, then in requisition for input V0~V255Driving voltage.In the present embodiment, with corresponding first driving of the first pixel unit Voltage class is voltage levels, exemplified by corresponding second drive voltage level of the second pixel unit is low-voltage-grade, if appointing The grayscale of one sub-pixel is denoted as K, and corresponding preset voltage value is Vk(0≤k≤255, k are integer), then to the first pixel list Each sub-pixel input voltage value in member is higher than VkDriving voltage, in the second pixel unit each sub-pixel input electricity Pressure value is less than VkDriving voltage.Since the first pixel unit is disposed adjacent with second pixel unit in display panel, So so that the voltage class height of the driving voltage per two neighboring pixel unit is different so that pixel unit is at side view angle Under gray-scale intensity curve close to the gray-scale intensity curve under positive visual angle, so as to improve the colour cast problem under side view angle.
