Because grating 1 (TN1) is that complementation is staggered with grating 2 (TN2), therefore, a left side, right eye in the even number frequency time-division although the sub-pixel of seeing, just in time with a left side, right eye in the odd number frequency time-division although the sub-pixel of seeing is adjacent, in other words, in a display cycle, a left side, right eye will be seen the figure of two groups of 64 * 160 different and adjacent pixels respectively, under the effect of persistence of vision, the visual experience of human eye etc. is both the figure of seeing one group of 128 * 160 pixel, moreover, because a left side, right eye is to see different independent images respectively, therefore, under the bore hole vision, will present the 3D image of 128 * 160 pixels.
As shown in Figure 3, at different gratings 1 (T1) and grating 2 (T2) in the time, fixing sub-pixel can be with the switching time of grating 1 with grating 2, the display data that conversion watches for left eye or right eye.
Fig. 4 is known 3D stereo display method, each time that opens and closes of grating 1 (T1) and grating 2 (T2) of can finding out remains on 8.3ms, in the time of odd number frame (Odd Field) and even number frame (Even Field), because scanning, display frame do not finish, so during odd number frame and even number frame scan, there is a set time need close backlight, wait for liquid crystal stable state (LCD formation) time afterwards, this is partly for after having scanned the last item scanning linear (scan line), required consumed time is finished in the start of wait liquid crystal, after finishing, again backlight is activated, this moment, human eye could be accepted correct 3D image, however the shortcoming that the briliancy that this type of drive can cause whole 3D to show descends.
