Description
Technical field
The present invention relates to a kind of 3 d display device and display packing thereof, relate in particular to a kind of 3 d display device and display packing thereof that cooperates polaroid glasses to reach the stereo display effect.
Background technology
Stereo display technique has become one of important directions of display technique development now because the beholder can be provided lively stereo-picture.Please refer to Fig. 1 and Fig. 2.Fig. 1 is the synoptic diagram of existing shutter glasses type (shutter glasstype) 3 d display device, and Fig. 2 is for the running synoptic diagram of existing shutter glasses type 3 d display device.As shown in Figure 1, shutter glasses type 3 d display device 1 mainly comprises display panel 10, and shutter glasses 12.When display frame, display panel 10 is understood the left eye picture of watching with scan mode Alternation Display confession in regular turn left eye 16, and the right eye picture 14 that supplies right eye to watch.When watching picture, shutter glasses that the beholder wore 12 can be allowed that target is observed according to display panel 10 picture displayed at present and see display panel 10 picture displayed, and be covered the sight line of non-target eye.As shown in Figure 2, the direction that display panel 10 is complied with circular arrow demonstrates the flow process of a complete picture frame (frame) in regular turn, and details are as follows for its flow process:
Time point t1: display panel 10 demonstrates a complete right eye picture 14, and this moment, the All Ranges of display panel 10 all demonstrated the information of watching for right eye; Shutter glasses 12 can cover the left eye sight line and made beholder's left eye can't see the right eye picture 14 that display panel 10 shows this moment, and only allowed that beholder's right eye sees the right eye picture 14 that display panel 10 shows;
Time point t2: begin to scan left eye picture 16, this moment, display panel 10 had the small part zone to demonstrate left eye picture 16, but right eye picture 14 is still possessed in most of zone; Shutter glasses 12 still can cover the left eye sight line and made beholder's left eye can't see the right eye picture 14 that display panel 10 shows this moment, and still make right eye can watch right eye picture 14, because the right eye information of display panel 10 demonstrations this moment is still much larger than left eye information, therefore the left eye picture 16 unlikely influences of small part are too big, but for reducing the influence of 16 pairs of right eyes of left eye picture, the right eye transmittance of shutter glasses 12 is descended, the left eye picture 16 brightness meetings seen of beholder descend thus, reduce the influence of 16 pairs of right eyes of left eye picture by this;
Time point t3: continue scanning left eye picture 16, this moment, display panel 10 had more that multizone has demonstrated left eye picture 16, and made left eye information close with right eye information; Disturb for avoiding information this moment, and shutter glasses 12 can cover left eye in the lump and the right eye sight line makes the beholder can't receive this mixed information;
Time point t4: continue scanning left eye picture 16, this moment, most of zone of display panel 10 demonstrated left eye picture 16, and only right eye picture 14 is still possessed in the small part zone; This moment, shutter glasses 12 can cover the right eye sight line, and the left eye of allowing the beholder is watched left eye picture 16, because the left eye information of display panel 10 demonstrations this moment is much larger than right eye information, therefore the right eye picture 14 unlikely influences of small part are too big, but for reducing the influence of 14 pairs of left eyes of right eye picture, the left eye transmittance of shutter glasses 12 is descended, and the right eye picture 14 brightness meetings seen of beholder descend thus, reduce the influence of 14 pairs of left eyes of right eye picture by this;
Time point t5: display panel 10 has shown a complete left eye picture 16, so the All Ranges of display panel 10 all demonstrates the information of watching for left eye; Shutter glasses 12 can cover the right eye sight line and made beholder's right eye can't see the left eye picture 16 that display panel 10 shows this moment, and only allowed that beholder's left eye sees the left eye picture 16 that display panel 10 shows;
In time point t6, t7, t8, display panel 10 can be according to above-mentioned mode, the scanning of beginning right eye picture 14, make left eye picture 16 change right eye picture 14 gradually into, and shutter glasses 12 also can be done corresponding variation, and display panel 10 can demonstrate complete right eye picture 14 once again when time point t1.
From the above, in order to keep the effect of stereo display, in procedure for displaying, for having comprised left eye information and right eye information simultaneously and the unconspicuous part picture of both quantity of information difference (time point the t3 as shown in Figure 2 and display frame of t7) must be given up, otherwise no matter be that left eye or right eye receive this picture and all can cause beholder's consciousness to obscure.Yet, will make the brightness of existing shutter glasses type 3 d display device 1 reduce than (frame rate), and influenced display quality with picture frame because the part picture can't use.
In addition, comprise space formula stereo display technique in the prior art in addition, its principle makes display panel demonstrate two groups of pictures that supply left eye and right eye to watch respectively simultaneously, and makes beholder's left eye only receive the left eye picture, and right eye only receives the right eye picture.Yet,, therefore can descend 50%, so have the shortcoming of low resolution in resolution in some cases because display panel must demonstrate two group of pictures simultaneously.
Summary of the invention
The technical matters that the present invention solves is, a kind of 3 d display device is provided, to promote picture frame than showing with brightness.
For reaching above-mentioned purpose, the invention provides a kind of 3 d display device, comprising: a display panel, comprise a display surface, wherein this display panel alternately provides one first display message and one second display message with scan mode; An and smooth changing device, a side that is arranged at this display surface of this display panel also receives this first display message and this second display message that is transmitted by this display panel, wherein this light changing device and this display panel scan and alternately provide one first changing mode and one second changing mode with the method for synchronization, wherein this first changing mode is corresponding to this first display message, make this first display message have one first polarization state, and this second changing mode makes this second display message have one second polarization state corresponding to this second display message.
For reaching above-mentioned purpose, the present invention also provides a kind of stereoscopic picture plane display method, comprising: utilize a display panel alternately to provide one first display message and one second display message with scan mode; And utilize a smooth changing device, this first display message and this second display message that reception is transmitted by this display panel, and make this light changing device and this display panel scan and alternately provide one first changing mode and one second changing mode with the method for synchronization, wherein this first changing mode is corresponding to this first display message, so that this first display message has one first polarization state, and this second changing mode is corresponding to this second display message, so that this second display message has one second polarization state.
Because the light changing device of 3 d display device utilization of the present invention and display panel synchronous scanning is reached the effect of stereo display, have therefore that higher picture frame compares, higher brightness, and use light and advantage such as lower-cost polaroid glasses.
