Description

Wide-angle liquid crystal display and driving method thereof
Technical field
The present invention relates to a kind of driving method of LCD, particularly a kind of wide-angle liquid crystal display and driving method thereof.
Background technology
Conventional liquid crystal (LCD) can produce the situation of brightness and contrast difference because of the difference of user's viewing angle, even with great visual angle the time, can produce the phenomenon of gray-scale inversion.In order to improve this phenomenon, there is the multiple domain of employing to cut apart vertical orientation (multi-domain vertical alignments, MVA) operator, it adopts 45 °, 135 °, 225 °, solves tradition gray-scale inversion phenomenon with great visual angle with the liquid crystal arrangement zone at 315 ° of four kinds of position angles (azimuthal angle).Fig. 1 shows that traditional multiple domain cuts apart gamma (gamma) curve of vertical orientation (MVA) LCD, wherein, the transverse axis coordinate is represented normalization (normalized) magnitude of voltage of drive signal, and longitudinal axis coordinate is represented normalization (normalized) value of brightness (luminance); Gamma (gamma) curve of (normal viewing angle) is faced in dotted line representative in the accompanying drawing, and solid line is then represented gamma (gamma) curve of stravismus (oblique viewing angle).As shown in the figure, the gamma of stravismus (gamma) curve has metaboly, and it is more obvious that this phenomenon can become under with great visual angle, even produces the phenomenon of colour cast (color washout).
In order to solve this problem, can adopt gamma (gamma) curve deformation of the mode of mixing two groups of gammas (gamma) curve under suppressing with great visual angle, shown in Fig. 2 A.In the accompanying drawings, the gamma curves 1 that right dotted line representative is faced, another gamma curves 2 that left dotted line representative is faced, diagonal dashed lines are then for blending together gamma curves through facing of mixing; The gamma curves 1 of right solid line representative stravismus, another gamma curves 2 of left solid line representative stravismus, the diagonal angle solid line then blendes together gamma curves for the stravismus through mixing.Learnt that by accompanying drawing stravismus blendes together oriented the facing of gamma curves (diagonal angle solid line) and blendes together the approaching tendency of gamma curves (diagonal dashed lines), this can improve color offset phenomenon with great visual angle.
Blending together of above-mentioned traditional two groups of gammas (gamma) curve has two kinds of driving methods: the time blendes together (dithering intime-domain) and the space blendes together (dithering in space-domain).The former is as United States Patent (USP) the 5th, 969, and No. 700 and U.S. patent application case disclose the revealer of the 2003/0006952nd A1 institute; No. the 5th, 877,737, the latter such as United States Patent (USP) and U.S. patent application case disclose the revealer of the 2004/0135755th A1 institute.
The effect that time blendes together depends on the speed of liquid crystal reaction, and the curve shown in Fig. 2 A is the result under the perfect condition; If liquid crystal failed to show required optical characteristics in the time of estimating, will form the imperfect result shown in Fig. 2 B, its stravismus blendes together gamma curves (diagonal angle solid line) the distortion situation, therefore also just can't effectively improve color offset phenomenon with great visual angle.
Though the space blendes together the reaction velocity that method must not considered liquid crystal, it uses several pixels (pixels) to show the mean flow rate of pixel, thereby causes the resolution of vision to descend.Simultaneously,, between the neighbor bigger luminance difference must be arranged, produce tangible broken shape edge in the time of will making video picture in order to obtain the effect of preferable inhibition colour cast.Fig. 2 C shows the video picture that usage space not blendes together, and Fig. 2 D shows that then usage space blendes together the video picture at the back institute tool that causes fragmentation shape edge.
Indulge the above, tradition sees through the type of drive that time or space blend together purely, and fails to solve the colour cast problem that LCD is produced with great visual angle the time.
Summary of the invention
One of purpose of the present invention is to propose a kind of wide-angle liquid crystal display and driving method thereof, in order to improve the color offset phenomenon with great visual angle of LCD.
Another object of the present invention is to propose a kind of wide-angle liquid crystal display and driving method thereof, the time that makes blendes together the reaction velocity that is not subject to liquid crystal, and makes the space blend together can not to produce tangible broken shape edge, and can avoid the reduction of resolution.
According to above-mentioned purpose, the present invention discloses a kind of Liquid Crystal Display And Method For Driving.According to embodiments of the invention, each sub-pixel (sub-pixel) of LCD comprises first pixel region and second pixel region at least.In regular turn in two adjacent during or neighbor, drive first pixel region and second pixel region with a plurality of driving voltages, thereby obtain two mean flow rates in regular turn; Or in regular turn in the two combination, thereby obtain four mean flow rates in regular turn.Wherein, these two mean flow rates are to determine by the space proportion of adjusting time scale during adjacent or neighbor, and these four mean flow rates determine according to the two combination, thereby it is approximately identical to default pixel intensity to obtain an overall average brightness.
