As the further optimization of liquid crystal grating, described liquid crystal grating also comprises the first polaroid be placed in outside first substrate, and is placed in the second polaroid outside second substrate.
A kind of 3 d display device, comprise panel display module and the liquid crystal grating of stacked setting, described liquid crystal grating is liquid crystal grating as above.
For a driving method for 3 d display device as above, described driving method comprises the following steps:
First by external for the circuit lead of described liquid crystal grating drive unit, described drive unit individually can drive each independently drive electrode;
When the display of needs sectional perspective, remainder plane display simultaneously, drive singal is applied to the wherein part drive electrode of liquid crystal grating respectively by drive unit simultaneously, meanwhile remaining drive electrode does not apply drive singal, the region now obtaining the part drive electrode of drive singal in liquid crystal grating just can produce chequered with black and white striped, form stereo display, all the other regions that there is no the drive electrode of drive singal are still pellucidity simultaneously, form plane display.
When needs switch to full frame stereoscopic display mode, the drive electrode whole to liquid crystal grating by drive unit all applies drive singal, with the striped making the region-wide generation of liquid crystal grating chequered with black and white, and now 3 d display device full screen display stereo-picture.
When needs switch to full frame plane display mode, by drive unit, drive singal is not applied to the whole drive electrode of liquid crystal grating, to make liquid crystal grating region-wide for pellucidity, now 3 d display device full screen display plane picture.
As the further optimization of driving method, described in the drive singal be applied on drive electrode be square-wave voltage.
The present invention has the following advantages compared to existing technology:
3 d display device provided by the invention, the second electrode structure due to its liquid crystal grating adopts electrode compartments independently to control, 3 d display device local repressentation stereo-picture can be made, meanwhile other region display plane images, namely realize plane display compatible in same screen with stereo display.Simultaneously, because the first electrode structure of liquid crystal grating adopts the strip electrode of inclination, compared with common vertical stripes electrode liquid crystal grating, moire fringes during stereo display can be effectively reduced, balance the resolution loss of 3 d display device horizontal direction and vertical direction when stereo display simultaneously, improve picture quality during stereo display.In addition, owing to adopting liquid crystal grating, 3 d display device, when carrying out plane display, the key property such as brightness, resolution parameter does not significantly change with panel display module originally, does not affect the quality that observer uses plane to show.
