Description
Technical field
The present invention relates to image display technology, especially a kind of liquid crystal cell, pointwise control device, Apparatus and method for.
Background technology
In an existing class 2D/3D switchable autostereoscopic display (see the open CN101387758A of the Chinese patent application being disclosed on March 18th, 2009), before common display screen, one piece of TN box is as shown in Figure 1 set as light shifter, by controlling the polarization direction of emergent ray to described TN box impressed voltage, thus the display realizing 2D and 3D switches.Obviously, this TN box, once switch, is entire screen switch, and the pointwise can not carrying out 2D/3D switches.
For solving the problem, existing another kind of 2D/3D switchable autostereoscopic display adopts thin film transistor (TFT) (ThinFilmTransistor, TFT) the TN box of type is as light shifter, the switching that TN box due to TFT type can carry out pixel controls, and is therefore very easy to the 2D image of local repressentation panel and the switching display of 3D rendering.But the complex manufacturing technology of TFT, involve great expense, and owing to needing the circuit such as signal wire, grid line arranging opaque TFT circuit on the transparent substrate, therefore must adopt black Matrix cover wiring area, cause effective display area to reduce, aperture opening ratio reduces, and the existence of black matrix may affect the display quality of picture, if remove black matrix, then can produce bright line at the edge of electrode, affect the display quality of picture equally.
The current 2D-3D 3 d display device also having a kind of pointwise control device and use this kind of pointwise control device, pointwise can not only control the polarization direction of incident ray polarized light, and display area can be increased, improve aperture opening ratio, eliminate bright line between electrode, improve display quality.But due to the architecture design of TN and the driving method of TN box, some 3D frameworks or foolproof shape profile can only be realized roughly over the display, the display logic of real pointwise can not be realized at present.
As shown in Figure 1, can not show or situation that display effect is deteriorated if will run into when the mechanism of the TN box 2D/3D display device based at present design will show the 3D framework shape model of a or b in Fig. 1.First the framework shape that current design can only show straight line 3D can not show curve as a situation.Time based on b situation, if two frameworks have superposition in level or vertical extended line direction, current display device can also become do not have between two figures to contact the region that should not show 3D picture in other words conj.or perhaps into 3D region, so just do not meet the display logic of device design itself, the actual viewing demand of beholder cannot be met.
Say toward dark one deck again, increase display effect required along with beholder, especially can require to increase further to 3D effect.Spectators can not be satisfied with a window again, or the display effect of an irregular window.Such as everybody is in television-viewing tennis tournament, and the leading role in tennis court should be two players played ball, so everybody focus is all with it the player of match, certainly also has a tennis.If so players given prominence to as the theme of stereo display separately when this match of display, such 2D/3D is the more focal effect of meeting on a picture jointly, and the sensation of scene also can more shake.
Similar this example has a lot, all this application all need one irregular and be real-time the moving fast along with focus object and show of dynamic forms.Such display requires that the device controlling stereoeffect should have matrix can the basic function of Quick-Point scanning.
At present because the principle of passive TN driving element limit, these are made to utilize switching 3 d display device as 2D-3D and can't carrying out the switching of quick multichannel point by point scanning formula of TN box.So the driving element that on the display device that screen is large or on the very high device of resolution, whole screen does a passive multichannel dynamic scan can't meet the demands.
