Fig. 1 is the colour cast situation schematic diagram of the various representative colour systems of liquid crystal display, with reference to Fig. 1, it is apparent that, respectively More or less all there is colour cast in a representativeness colour system, ordinate is bigger to illustrate that colour cast is more serious, and wherein R color colour system and green color The colour cast of system is more serious.

Exemplary solution is by that RGB (Red, Green, Blue) each sub-pixel will be further subdivided into major/minor picture Plain (Main/Sub), so that whole big visual angle brightness is closer to face with voltage change.

Fig. 2 is the first schematic diagram that pixel is divided into major/minor pixel by exemplary arrangement, and Fig. 3 is exemplary arrangement by picture Element is divided into the second schematic diagram of major/minor pixel, knows referring to figs. 2 and 3, wherein the x coordinate, y-coordinate and z coordinate, respectively Represent three directions of three-dimensional space；The θ A indicates that the pre-dumping lead angle under the wherein big voltage of main pixel, the θ B indicate wherein secondary picture Pre-dumping lead angle under plain small voltage.

Specifically, original signal to be divided into the primary and secondary pixel of big voltage+small voltage, facing big voltage will maintain plus small voltage Original faces signal with brightness change, and Part A of the side view brightness that big voltage is seen with gray scale variation as shown in figure 1, small voltage is seen Part B of the side view brightness with gray scale variation as shown in figure 1.Side view synthesizes the brightness seemed with gray scale variation just by two in this way The arc segment of dotted line becomes solid line arc segment, so visual angle brightness is with signal intensity relationship close to facing original signal brightness with letter Number variation so that visual angle is improved.

It is this by spatially primary and secondary pixel to give different driving voltages to solve visual angle colour cast and obtain defect, such picture Element design generally requires redesign metal routing or thin film transistor (TFT) (Thin Film Transistor, TFT) element to drive Sub-pixel causes light-permeable open region sacrifice, influences the saturating rate of panel, directly contributes the promotion of backlight cost.

Below with reference to the accompanying drawings the invention will be further described with optional embodiment.

Fig. 4 is a kind of driving method flow chart of the embodiment of the present invention, and Fig. 5 is a kind of driving method of another embodiment of the present invention Flow chart, with reference to known to Fig. 4 and Fig. 5:

The driving method comprising steps of

S11: multiple signals are divided into previously according to corresponding second color signal of pixel and judge section, and to induction signal Judge the preset condition in section；

S12: corresponding first color signal of all pixels is received, second face is converted to according to the first color signal Chrominance signal；

S13: relatively and judging that signal locating for the second color signal judges section, meanwhile, judge whether to meet locating letter Number judge the corresponding preset condition in section；Section and preset condition judgement knot are judged according to signal locating for the second color signal Fruit is a period sub-pixel to be determined to be divided into multiple periods with 2n adjacent homochromy sub-pixels to be determined, wait sentence Determining sub-pixel group is to determine the first driving method sub-pixel and the second driving method sub-pixel respectively in unit each period；

S124: corresponding first sub-pixel of the first driving method sub-pixel and the second sub- picture are driven with the first driving method Element, while the corresponding first sub-pixel and second sub-pixel of the second driving method sub-pixel are driven with the second driving method；

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.

Relative to Fig. 1 and shown in Fig. 2, by by each sub-pixel (such as red sub-pixel, green sub-pixels and blue Pixel) it is divided into primary and secondary (Main/Sub) pixel, and discharge switch and discharge capacity are connected to sub-pixel to improve the side of colour cast Case.The present invention realizes that a brightness is presented using two adjacent sub-pixel signals, but before realizing that brightness is presented, first First color signal of the frame image is converted into the second color signal, and judges that signal locating for the second color signal judges Section and the case where meet preset condition, to determine the colour cast and granular sensation situation of the frame image, thus the drive that selection is applicable Flowing mode drives sub-pixel to be determined；Specifically, if colour cast within the period it is obvious that can then determine most of to be determined Sub-pixel or all sub-pixel to be determined are applicable in the grey biggish driving method of scale to drive to improve colour cast；Similarly, if if Colour cast is unobvious, then can be determined within the period most of sub-pixel to be determined or all sub-pixel to be determined be applicable in grey scale compared with Small driving method drives to improve granular sensation.

Wherein, it largely refers to being greater than half, and less than or equal to the sum of sub-pixel to be determined in the period.

Wherein, actually there is no the structures for changing pixel by the present invention, because without reducing aperture opening ratio, specifically, passing through Adjacent two realize that an average brightness is presented with sub-pixels, and are provided with the different driving of at least two grey scales Mode is for selection, in this way, just can on the basis of not reducing aperture opening ratio, improved by Design of Signal appropriate colour cast or Granular sensation.

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.

In one embodiment, the hue range of the second color signal are as follows: 0-360, corresponding 0-360 degree；

Form and aspect H the second color signal for meeting following formula is divided into the 6th signal and judges section: 295 H≤315 <. In the present embodiment, the second color signal is judged into section according to form and aspect different demarcation for multiple signals, then may determine that the area Between colour cast degree it is whether serious, for example, when other conditions are identical, if the second color signal be located at the first signal judge section or Person says that red color phase section and third signal judge section green hue section in other words, then colour cast is serious, at this point, preferentially The driving method that selects grey scale big drives sub-pixel to be determined to improve colour cast；And if the second color signal is located at the 5th letter When number judging section, then form and aspect are not biased towards red color phase and are also not biased towards green hue, at this point, colour cast is very light, preferentially select grayscale Difference small driving method drives sub-pixel to be determined, to improve granular sensation.

Wherein it is possible to which corresponding first signal judges that section setting preset condition for CTL1≤C≤CTH2, corresponds to second signal Section setting preset condition is judged for CTL3≤C≤CTH4, and corresponding third signal judges section setting preset condition for CTL5≤C ≤ CTH6, corresponding fourth signal judge section setting preset condition for CTL7≤C≤CTH8, and corresponding 5th signal judges that section is set Setting preset condition is CTL9≤C≤CTH10, and corresponding 6th signal judge that preset condition is arranged as CTL11≤C≤CTH12 in section, Wherein, CTL1, CHH2, CTL3, CTH4, CTL5, CTH6, CTL7, CTH8, CTL9, CTH10, CTL11 and CTH12 are fixed in advance The chroma range of justice；Wherein, C is the chroma of the second color signal.Specifically, CTL1, CTL3, CTL5, CTL7, the CTL9 and CTL11 can be set identical, and difference also can be set；Phase can be set in CTH2, CTH4, CTH6, CTH8, CTH10 and the CTH12 Together, difference also can be set.Wherein, form and aspect cooperate chroma, can preferably react the colour cast severity of current picture.

In one embodiment, the preset condition is divided according to the chroma of the second color signal；When described second The chroma C of color signal meets following formula: when 40≤C≤80, determining that meeting locating signal judges the corresponding default item in section Part.In the present embodiment, for the sub-pixel signal of same same sub-pixels, in the range of chroma 0-100, due to Chroma is closely related with tone, and closer to chroma 50, closer to intermediate chroma, corresponding tone is also at semi-tone, at this moment The colour cast of time is relatively serious, starts color bias improvement mechanism at this time, can achieve preferable color bias improvement effect；Meanwhile general Picture in, the accounting of intermediate chroma is larger, also needs most improvement colour cast.Particularly, when form and aspect section is red color phase section When with green hue section, colour cast is originally relatively serious, and when chroma is located at the section of 40-80, the colour cast of current picture is very Seriously, it so at this time, needs to drive pixel with the first driving method, to improve colour cast.

More specifically, different form and aspect section, can also set preset condition to different ranges, such as can will be red Chrominance signal judges that the corresponding preset condition in section is set as 40≤C≤80, and green is judged the corresponding default item in section Part is set as 45≤C≤75.
