Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Consult Fig. 1, Fig. 1 is the structural representation of the utility model 3 d display device embodiment.The utility model 3 d display device embodiment comprises: display screen 11, electrical grating 12 and driving circuit 13.
Wherein, display screen 11 comprises a plurality of pixel cells 111, and electrical grating 12 is arranged at the display surface of display screen 11.Driving circuit 13 control electrical gratings 12, and when carrying out stereo display, as shown in Figure 2, electrical grating 12 will be from the separately light of the adjacent pixel unit 111 of display screen 11 selectively respectively to the direction outgoing of corresponding people's left eye and right eye, because of principle of parallax, thereby can present to the human-eye stereoscopic vision effect; And carrying out two dimension when showing, and electrical grating 12 will be from the separately light non-selectivity ground outgoing of the adjacent pixel unit 111 of display screen 11, and image is not changed, so human eye can be seen the two-dimensional visual effect.
Particularly, electrical grating 12 can be liquid crystal grating, and electrical grating 12 comprises upper polarizer 121, upper transparent electrode substrate 122, liquid crystal layer 123, lower transparent electrode substrate 124 and lower polaroid 125.Wherein, upper polarizer 121, upper transparent electrode substrate 122, liquid crystal layer 123, lower transparent electrode substrate 124 and lower polaroid 125 sequentially arrange from top to bottom, namely descend the display surface of polaroid 125 the most contiguous display screens 11.Wherein, upper transparent electrode substrate 122 and lower transparent electrode substrate 124 include the transparency electrode of a plurality of determinants, and upper transparent electrode substrate 122 connects respectively driving circuit 13 with transparency electrode in the lower transparent electrode substrate 124.Concrete, the transparency electrode of upper transparent electrode substrate 122 is upper transparency electrode (be 1221-1224 such as label among Fig. 1), lower transparent electrode substrate 124 is namely gone up transparency electrode and is connected respectively driving circuit 13 with lower transparency electrode for lower transparency electrode (be 1241-1244 such as label among Fig. 1).Wherein, a plurality of raster units (label is 1001-1004 as shown in Figure 1) of the pixel cell 111 of upper polarizer 121, upper transparent electrode substrate 122, liquid crystal layer 123, lower transparent electrode substrate 124 and the corresponding display screen 11 of lower polaroid 125 common definition.
The principle of work of the utility model embodiment is as follows:
When carrying out stereo display, driving circuit 13 applies voltages to the transparency electrode in transparent electrode substrate 122 or the lower transparent electrode substrate 124, make the slit of the part zone formation printing opacity in the raster unit, and the remainder shading so that from the separately light of the adjacent pixel unit 111 of display screen 11 by behind the slit optionally respectively to the direction outgoing of corresponding people's left eye and right eye;
When carrying out the two dimension demonstration, driving circuit 13 drives raster units, makes its whole viewing areas printing opacity, and then makes the separately light non-selectivity ground outgoing from the adjacent pixel unit 111 of display screen 11.Because through changing, what namely people's left eye and right eye were seen is not two-dimensional image to two-dimensional image, thereby realizes the visual effect that two dimension shows.
It should be noted that among the utility model embodiment, size and the position of the slit that forms when applying voltage to upper transparent electrode substrate 122 or lower transparent electrode substrate 124 by driving circuit 13 can be regulated, and see also Fig. 1-Fig. 6.Raster unit is generally a plurality of, for example, and as shown in Figure 1, can comprise raster unit 1001-1004, correspondingly, in conjunction with Fig. 3, upper transparent electrode substrate 122 comprises transparency electrode 1221-1224, and lower transparent electrode substrate 124 comprises lower transparent electrode substrate 1241-1244.
When all applying suitable voltage as 13 couples of upper transparency electrode 1221-1224 of driving circuit and to lower transparency electrode 1241-1244, at this moment, as shown in Figure 4, whole raster unit 1001-1004 all open, between the raster unit of adjacent unlatching, be d1 such as the spacing between raster unit 1001 and the raster unit 1002, namely the spacing of slit is d1;
