Fig. 3 is a kind of driving method flow chart of the present invention, with reference to known to Fig. 3:
The present invention provides a kind of driving method of display panel, the display panel includes multiple pixels, each described
Pixel includes multiple heterochromatic sub-pixels；At least one of described sub-pixel is sub-pixel to be determined, and adjacent two homochromy

Wherein, under the first adjustment mode and second adjustment mode, the corresponding sub- picture of first sub-pixel and second sub-pixel
The average grayscale of plain signal is suitable, and grey scale is different；N is the natural number more than or equal to 1, and the value of 2n is less than sub-pixel to be determined
Sum.
In the present invention, relative to shown in Fig. 1 and Fig. 2, by the way that each pixel is divided into primary and secondary (Main/Sub) pixel, and give
Sub-pixel connects discharge switch and discharge capacity with convenient, so that main pixel and sub-pixel have different charging voltages to change
The scheme of kind colour cast.In the present invention, receives and count the corresponding sub-pixel signal of sub-pixel to be determined, in each signal spacing
Distribution situation；And search maximum ratio section, then it can illustrate, the main display characteristic of current picture, if maximum ratio area
Between corresponding sub-pixel to be determined luminance difference it is big, granular sensation is obvious, then illustrates that current picture granular sensation is relatively obvious, can be with
Most sub-pixel to be determined is determined within the period, and granular sensation has been improved to drive with the lesser adjustment mode of grey scale；Together
Reason, if the luminance difference of the corresponding sub-pixel to be determined in maximum ratio section is small, granular sensation is unobvious, then illustrates current picture
Granular sensation is not serious, at this point, most sub-pixel to be determined should be determined within the period, to select the biggish adjustment of grey scale
Mode drives to improve colour cast.Wherein, the half at least over sub-pixel quantity to be determined in the period is largely referred to.
In addition, since the present invention can not change the structure of pixel, thus, driving method of the invention will not reduce opening
Rate advantageously reduces power consumption, so, it is possible on the basis of not reducing aperture opening ratio, improves colour cast and granular sensation.Wherein, this is pre-
If the setting of specification ratio value with the signal of division judge section quantity hook, when signal judge section quantity it is more when,
Pre-set specifications ratio value is smaller, and when signal judges the negligible amounts in section, pre-set specifications ratio value is larger；Such as when signal is sentenced
When the quantity in disconnected section is 3, three signals judge that the pre-set specifications ratio value in section can be Gth1=Gth2=Gth3=
30%, it is of course also possible to which Set scale is different, it is adjusted according to the actual situation.
Wherein, the pre-set specifications ratio value can also be calculated one according to the sum and ratio of sub-pixel to be determined
Then when actual count without calculating ratio value, and numerical threshold is arranged in a specific quantity, is calculated with saving
Amount.
Wherein, average grayscale, the i.e. grayscale value of the corresponding sub-pixel signal of the first sub-pixel are corresponding with the second sub-pixel
The average value of the grayscale value of sub-pixel signal, i.e., under the first adjustment mode and second adjustment mode, the first sub-pixel and second
The average brightness of sub-pixel presents suitable.Wherein, average grayscale is suitable, refers in the first adjustment mode and second adjustment mode
Under, the average grayscale size of first sub-pixel and second sub-pixel is the same, certainly, in the first adjustment mode and second adjustment mode
Under, the average grayscale of first sub-pixel and second sub-pixel is not quite identical, but the difference of size is less than preset range, example
Such as, when error is less than 0.5 grayscale, it is believed that two average grayscale sizableness.
Wherein, adjacent to refer in display panel, homochromy sub-pixel is along scan line or along data line direction, setting
Position it is adjacent, such as in Fig. 5, the R1,1 and R2,1 is adjacent in the direction along data line, and certainly, the framework of display panel is different
When, it can also be adjacent along scanning line direction；Similarly, 2n adjacent homochromy sub-pixels to be determined are a period, hot dice
For pixel is sub-pixel signal to be determined, 2,4,6 ... adjacent red sub-pixels be a period, by red sub-pixel
It is divided into multiple periods, wherein depending on the value of n can judge section according to signal locating for average value, locating for average value
Signal judges the sub-pixel to be determined in section, and the grey scale of corresponding sub-pixel high voltage signal and sub-pixel low voltage signal is got over
When big, the value of n is bigger；The value of certain n can also be modified according to presetting.
And it is corresponding, the 2m be then judge that the value of section and 2n are configured based on signal locating for average value, for example,
When the value of 2n is 8, the value of 2m can take 2,4,6,8, and specific value, the signal according to locating for average value judges that section is determined
Determine, such as signal locating for average value judges that the granular sensation of section surface current picture is serious, then the value of 2m takes the larger value；Instead
It, then take smaller value, improves granular sensation or colour cast with emphasis.
Wherein, the rule that 2m chooses is that it is weaker can preferentially to choose granular sensation as unit of sub-pixel group to be determined
Sub-pixel to be determined, it is of course also possible to randomly select.
In one embodiment, it is described according to maximum ratio section with 2n adjacent homochromy sub-pixels to be determined for one week
Sub-pixel to be determined is divided into multiple periods by the phase, and each period determines the first adjustment respectively as unit of sub-pixel group to be determined
The step S13 of mode sub-pixel and second adjustment mode sub-pixel includes:
It with 2n adjacent homochromy sub-pixels to be determined is one group by all sub- pictures to be determined according to maximum ratio section
Element is divided into multiple periods, and each period determines that 2m sub-pixels to be determined are first respectively as unit of sub-pixel group to be determined
Adjustment mode sub-pixel, meanwhile, determine that remaining sub-pixel to be determined in the period is second adjustment mode sub-pixel；Wherein, m is
The value of natural number more than or equal to 1,2m is less than or equal to 2n.
In the present embodiment, if the luminance difference of the corresponding sub-pixel to be determined in maximum ratio section is big, granular sensation is bright
It is aobvious, then make the value of 2m be greater than 0 and be less than n, so that it is determined that most sub-pixel to be determined in the period, smaller with grey scale
Adjustment mode improved granular sensation to drive；Similarly, if the luminance difference of the corresponding sub-pixel to be determined in maximum ratio section
Different small, granular sensation is unobvious, then illustrates that current picture granular sensation is not serious, at this point, then make the value of 2m be greater than n and be less than etc.
In 2n, so that it is determined that most sub-pixel to be determined in the period, is driven with selecting the grey biggish adjustment mode of scale to change
Kind colour cast.
In one embodiment, it is described according to maximum ratio section with 2n adjacent homochromy sub-pixels to be determined for one group
All sub-pixels to be determined are divided into multiple periods, as unit of sub-pixel group to be determined each period determine respectively 2m to
Determine that sub-pixel is the first adjustment mode sub-pixel, meanwhile, determine that remaining sub-pixel to be determined in the period is second adjustment side
The step S13 of formula pixel includes:
It with 2n adjacent homochromy sub-pixels to be determined is one group by all sub- pictures to be determined according to maximum ratio section
Element is divided into multiple periods, and each period determines that 2 sub-pixels to be determined are first respectively as unit of sub-pixel group to be determined
Adjustment mode sub-pixel, meanwhile, determine that remaining sub-pixel to be determined in the period is second adjustment mode sub-pixel；
Wherein, the sub-pixel to be determined in maximum ratio section, corresponding sub-pixel high voltage signal and sub-pixel low-voltage
The grey scale of signal is bigger, and the value of 2n is bigger.In the present embodiment, be arranged each period only determine 2 sub-pixels to be determined
For the first adjustment mode sub-pixel, but the quantity of the sub-pixel that is included of each period is different according to maximum ratio section and sets
Set difference；If maximum ratio section is located at the serious section of granular sensation, it includes more sub-pixel quantity that each period, which is arranged,
