As shown in Figure 1, in order to promote the visual angle, traditional liquid crystal panel forms thrust (protrusion) 13 between two substrates 11 and 12, so that liquid crystal molecule 14 produces tilt angle (pre-tilt angle).But so can cause dark attitude light leak and reduce the effective vent rate, cause contrast and luminance shortage, and can't solve the problem of colour cast.Moreover the design of thrust must be used one color filter film processing procedure more, and has increased the complicacy of processing procedure.
In addition, be subject to the reaction velocity of liquid crystal itself, the drive pattern of the formula of keeping (holdtype) that present liquid crystal panel is adopted under dynamic menu, can produce the problem of smear to human eye.Fig. 2 A puts on the driving voltage Vd of pixel and the graph of a relation of time t for foundation GTG value.Suppose that a pixel is respectively 34,100,30 in the pixel value of each image time T1, T2 and T3.Driving voltage Vd is to determine according to these a little pixel values in the value of image time T1, T2 and T3.Fig. 2 B is according to the brightness L of the pixel of the driving voltage of Fig. 2 A and the graph of a relation of time t.Brightness line 21 is depicted as the brightness that pixel basis driving voltage Vd is ideally presented.And in fact, therefore the speed that the liquid crystal molecule reaction velocity changes less than electric field need reaction time of one period could arrive the brightness of target.Be the brightness that pixel basis driving voltage Vd is in fact presented shown in the brightness line 22.Because the liquid crystal molecule reaction velocity of pixel is fast inadequately, dynamic picture just has smear easily, influences display quality.

General panel is by the flow process of vertical synchronizing signal Vs (Vertical synchronization signal) with horizontal-drive signal Hs (Horizontal synchronization signal) control demonstration.Show 60 pictures (frame) in this panel one second, so each image time (frame time) be 1/60=16.7ms, this is controlled by vertical synchronizing signal Vs, so the frequency f (Vs) of known vertical synchronizing signal Vs is 60Hz.And each picture has 600 horizontal lines, and scanning can be finished a picture one by one, and this is controlled by horizontal-drive signal Hs, and therefore the frequency f (Hs) of known horizontal-drive signal Hs is 600*f (Vs)=36000Hz.Each horizontal line has 800 to draw point, draw point for one and comprise red, blue, green three pixels, so each horizontal line has 800*3=2400 pixel.The frequency of the pixel clock signal Cp (pixel clock signal) of control pixel bit stream (bitstream) input liquid crystal panel is 2400*f (Hs)=86400000Hz.The length of supposing each pixel value of this panel is 8, and 0～254 GTG value is just arranged, and required corresponding driving voltage is 0～5V.The relation of pixel value and driving voltage is not pure linearity, generally learns driving voltage corresponding to pixel value with look-up table.
See also Fig. 5 A, it is the driving voltage synoptic diagram according to a kind of liquid crystal panel drive method of first embodiment of the invention.Suppose to be respectively 30,200,30 in the pixel value D of image time T1, T2, T3.According to known driving method, can get via tabling look-up corresponding to the driving voltage of image time T1, T2 and T3, for example be essentially 0.6V, 4V and 0.6V respectively, shown in the dotted line among Fig. 5 A.This known driving method has the slow excessively shortcoming of reaction as previously mentioned.The present invention is characterised in that an image time is divided into preliminary filling time domain P (precharge field) and compensation time domain C (compensaion field).At this specific embodiment with preliminary filling time domain P preceding, compensation time domain C after be example.Pixel value corresponding to preliminary filling time domain P is max pixel value Gmax or minimum pixel value Gmin; In the pixel value of compensation time domain C then by suitably calculating, make corresponding to the pixel value of preliminary filling time domain P with on average equal the predetermined pixel value that shows corresponding to the pixel value of compensation time domain C.Image time T1 is divided into preliminary filling time domain P1 and compensation time domain C1; Image time T2 is divided into preliminary filling time domain P2 and compensation time domain C2; Image time T3 is divided into preliminary filling time domain P3 and compensation time domain C3.At first, the preliminary filling pixel value of decision preliminary filling time domain P, if the pixel value of image time greater than reference value then the preliminary filling pixel value be max pixel value Gmax, otherwise the preliminary filling pixel value is minimum pixel value Gmin.Reference value is to adjust according to the characteristic of liquid crystal panel, is example at this with 128.The pixel value of image time T1 is 30, and less than reference value (128), so the preliminary filling pixel value of preliminary filling time domain P1 is minimum pixel value Gmin, just 0.The compensation pixel value of compensation time domain C1 then is 60.The pixel value that on average is image time T1 (30) of the compensation pixel value of the preliminary filling pixel value of preliminary filling time domain P1 and compensation time domain C1.The pixel value of image time T2 is 200, and greater than reference value (128), so the preliminary filling pixel value of preliminary filling time domain P2 is max pixel value Gmax, just 254.The compensation pixel value of compensation time domain C2 then is 146.The pixel value that on average is image time T2 (200) of the compensation pixel value of the preliminary filling pixel value of preliminary filling time domain P2 and compensation time domain C1.The pixel value of image time T3 is 30, and less than reference value (128), so the preliminary filling pixel value of preliminary filling time domain P3 is minimum pixel value Gmin, just 0.The compensation pixel value of compensation time domain C3 then is 60.The pixel value that on average is image time T3 (30) of the compensation pixel value of the preliminary filling pixel value of preliminary filling time domain P3 and compensation time domain C3.Promptly can the corresponding driving voltage of look-up table decision according to pixel value in advance that is determined and compensation pixel value.Utilize this specific embodiment gained in the driving voltage of each time domain, shown in Fig. 5 A, be about 0,1.2,5,2.8,0 respectively in regular turn, 1.2V.
Fig. 5 B is the pixel intensity synoptic diagram according to the driving voltage of Fig. 5 A.Dotted line is depicted as desirable pixel intensity, but because of liquid crystal molecule is not real time reaction, so brightness changes shown in solid line.With image time T2 explanation as after.When time domain P2 in advance, the brightness of pixel rises to maximal value, because the driving voltage of this moment is bigger than known, the reaction time of therefore rising is faster than known method.When compensation time domain C2, the brightness of pixel promptly begins to descend then, because the driving voltage of this moment is littler than known, the reaction time that therefore descends is also fast than known method.And more near the display mode of pulsed, it is residual to reduce the human eye vision that the formula display mode of keeping causes compared with known brightness curve for the brightness curve of image time T2, to promote display quality.In addition, it should be noted that this specific embodiment all is to reach the intermediate pixel value from the highest or minimum pixel value, or by the intermediate pixel value to the highest or minimum pixel value, therefore avoided making the slowest situation of liquid crystal reaction velocity, thereby accelerated the reaction velocity of liquid crystal.
