In addition, in order to better the present invention is described, in embodiment hereafter, give numerous details.It will be appreciated by those skilled in the art that do not have some detail, the present invention can implement equally.In some instances, the method known for those skilled in the art, means, element and circuit are not described in detail, so that highlight purport of the present invention.
Because VA type LCDs easily produces the deviation of color and brightness when checking with great visual angle, make image fault.But this defect of VA type LCDs is that design is intrinsic, can only go to improve: can processing procedure be improved, also can improve type of drive as far as possible.The embodiment of the present invention proposes the simpler and easy and effective way of one: by System on Chip/SoC (SystemonChip, SOC) distortion gamma (Gamma) curve, improve colour cast with great visual angle, especially colour of skin picture, successful.
embodiment 1
Fig. 1 illustrates the process flow diagram of the display control method of LCDs according to an embodiment of the invention.As shown in Figure 1, the display control method of this LCDs is mainly used in the brightness value corresponding according to the grey decision-making of normal brightness change curve to pixel each in described LCDs and adjusts as follows:
Step 101, brightness value corresponding for the first grey decision-making be in the first grey-scale range to be adjusted to lower than described first grey decision-making brightness value corresponding on normal brightness change curve.
Step 102, brightness value corresponding for the 3rd grey decision-making mediated in grey-scale range is set to equal described 3rd grey decision-making brightness value corresponding on described normal brightness change curve.
Step 103, brightness value corresponding for the second grey decision-making be in the second grey-scale range to be adjusted to higher than described second grey decision-making brightness value corresponding on described normal brightness change curve.
In a kind of possible implementation, the grey-scale range of each pixel of LCDs is normally from 0 to 255, basic, normal, high three grey-scale range can be divided into by 0 to 255: the first grey-scale range is low GTG, comprise the low grey decision-making from 0 to first threshold; Middle grey-scale range is middle GTG, comprises the middle grey decision-making from first threshold to Second Threshold; Second grey-scale range is high gray, comprises the high gray value from Second Threshold to most high gray (such as often think 255 at present, but be not limited thereto).Wherein, the grey decision-making in described first grey-scale range is less than the grey decision-making in middle grey-scale range, and the grey decision-making in middle grey-scale range is less than the grey decision-making in the second grey-scale range.Wherein, also can not divide middle grey-scale range, but only will be divided into low GTG or high gray from 0 to 255, in the embodiment of the present invention, not limit the concrete division methods of grey-scale range.
The sequential relationship of not conditioning step 101 to step 103 in the embodiment of the present invention.Preferably, can according to the brightness value of grey decision-making order from low to high adjustment correspondence.Certainly, also according to from brightness value corresponding to grey decision-making order adjustment from high to low, or can adjust according to different grey-scale range segmentations.The brightness value that each grey decision-making in the middle grey-scale range of step 102 is corresponding also can be defaulted as and meet normal brightness change curve, and that can omit step 102 like this arranges action.
Specifically, in view of the apperceive characteristic of human eye, general LCDs all needs the form GTG of its each pixel and the relation of brightness being adjusted to the gamma curve see following formula 1:
Lv=Gray
γformula 1
Wherein Lv is brightness, and Gray is GTG.Preferably get γ=2.2, but be not limited to 2.2.
That is: face some point of fixity on display screen with nitometer, display screen display 0,1 ... the white picture of 255 grey decision-making, records brightness value now respectively.A solid line as above in Fig. 2 can be drawn.Now the observing effect of human eye is best, is illustrated in figure 4 picture when normally facing.
If but nitometer is deflected in the horizontal direction an angle facing to display screen, simulation people view screen from the side, larger skew can be there is, as the thick dashed line in Fig. 2 with the curve that said method is measured.Wherein, low gray-scale intensity is higher, and high gray brightness is on the low side.Now see that the picture on screen can observe whiting or even colour cast.As shown in Figure 5, picture when miter angle observes display screen from the side can obviously whiting.
The reason producing this phenomenon be with great visual angle time gamma curve (brightness change curve time with great visual angle) create larger deviation with ideal curve (normal brightness change curve), and this patent proposes a kind of way of turn-back gamma curve.
Because human eye is to the relative change of the change perception of brightness mainly brightness, if offset smoothly within the specific limits by ideal curve, human eye can not feel difference namely to there is a scope that can float significantly.Principle according to this, the curve that when we wish find a side-looking and face, picture can accept.
When facing, be Fig. 2 chain lines (after optimizing curve) by current brightness change curve (standard gamma curve) distortion.Low gray-scale intensity is carried out forcing down to a certain degree, and high gray brightness is suitably promoted, be illustrated in figure 3 the enlarged drawing of the brightness change curve of low GTG.Middle GTG can not deal with.Such as, low GTG is 0 to 30 GTG, and middle GTG is 31 to 240 GTGs, and high gray is 241 to 255 GTGs.Wherein, in the embodiment of the present invention, do not limit the concrete separation of low GTG, middle GTG, high gray, visual concrete condition sweetly disposition.Further, how many concrete adjustment is advisable, and also can do to weigh according to the picture improvement situation faced with side-looking.Total principle preferentially to ensure that facing picture does not occur obvious problem, take the circumstances into consideration with great visual angle to improve, and will make all can not occur significantly than situation poor before stretching gamma curve from positive visual angle to picture during maximum visual angle (90 degree) change of perspective.
When facing like this, people can not feel obvious brightness and color change.Be picture when facing after stretched curve as shown in Figure 6, compare not significantly change with before stretching.And because carried out negative drawing for curve of deviation during side-looking, its colour cast problem can be improved.As shown in Figure 7, be picture during stretching rear side viewing, had obvious improvement than the side view before stretching, picture is more clear, and color and brightness obvious distortion do not occur yet.
The display control method of the LCDs of the present embodiment, by distortion normal brightness change curve as gamma curve, can improve the colour cast with great visual angle of LCDs especially VA type LCDs, reduce distortion, improve display effect significantly.

Step 105, according to the grey decision-making in adopted adjustment curve and brightness value, control the driving voltage of the LCDs under perpendicular alignmnet drive pattern.
Want emphasis to improve the display effect of the colour of skin due to lower with great visual angle, and red meeting play major effect to the colour of skin, can increase the step of the whole red saturation scale of a step, to optimize display effect further after stretching Gamma.Therefore, in a kind of possible implementation, the display control method of this LCDs also comprises: adjust the red saturation scale of described pixel each in described LCDs.
