o, as shown in Figure 2.
Consult Fig. 6; Shutter glasses 22 has signal processor 222, that a signal receiver (Signal Receiver) 221, is electrically connected signal receiver 221 and is electrically connected the lens set 224 that the shutter driver (Shutter Driver) 223 and of signal processor 222 is electrically connected shutter driver 223, and the signal processor 222 of present embodiment is a decoder (Decoder).Lens set 224 has a left eyeglass lens 31 and a right eye eyeglass 32, but two eyeglasses, 31,32 controlled alternates are opened.
Shown in the step 901 of Fig. 3, the video-stream processor 211 of holographic display device 21 makes display screen 212 Alternation Display left eye pictures and right eye picture.Then; Shown in the step 902 of Fig. 3; The picture synchronization signal that the signal generator 213 of holographic display device 21 receives video-stream processor 211; And produce one in order to control the synchronous control signal (as shown in Figure 7) of shutter glasses 22; The synchronous control signal of present embodiment is a digital signal, but not as limit.Consult Fig. 7, synchronous control signal comprise a left eyeglass lens 31 that starts shutter glasses 22 and one initial (leading) instruction, of right eye eyeglass 32 define left eye shutter glasses 31 and 32 actions of right eye eyeglass cycle (T) first set information 41 and defines the work period (duty cycle) that left eyeglass lens 31 and right eye eyeglass 32 alternately open in the cycle (T) the second setting information 42.Further specify; Synchronous control signal as shown in Figure 7; First pulse 51 wherein is as initial order; And be defined as m the cycle (T) between first pulse, 51 to second pulses 52 (synchronous sequence benchmark); And the work period (duty cycle) that the pulse after second pulse is alternately opened with definition left eyeglass lens 31 and right eye eyeglass 32 as numerically coded instruction; Because the numerically coded instruction of this part is known by the personnel of technical field, so do not add narration.
Shown in the step 902 of Fig. 3 and consult Fig. 8, Postponement module 214 receives synchronous control signals, and synchronous control signal is postponed a Preset Time (Δ t), to proofread and correct the time drop in display screen 212 and shutter glasses 22 runnings.And the synchronous control signal of signal projector 215 receive delays and sends out synchronous control signal, is the signal projector of wireless telecommunications at the signal projector 215 of present embodiment.
Shown in the step 903 of Fig. 3, the signal receiver 221 of shutter glasses 22 receives the synchronous control signal of delay; Signal processor 222 is understood synchronous control signal; And according to the enabling signal of initial order (being exactly first pulse 51 of synchronous control signal) generation one startup left eyeglass lens 31 with right eye eyeglass 32; And set information 41 and second according to first in the synchronous control signal and set the cycle (T) that information 42 produces control left eyeglass lens 31 and 32 actions of right eye eyeglass, and a left eye drive signal and a right eye drive signal (as shown in Figure 9) of controlling 31 of left eye shutter glasses and the work period (duty cycle) of right eye eyeglass 32.Just; Signal processor 222 produces enabling signal according to first pulse 51; And the distance that measures first pulse, 51 to second pulses 52 is extrapolated the cycle (T); And the pulse after second pulse 52 of decoding is to define the work period (duty cycle) of left eyeglass lens 31 and right eye eyeglass 32; The work period of present embodiment, (duty cycle) was 40% of the cycle (T), was exactly the t among Fig. 9
1, the time of images of left and right eyes eyeglass 31,32 unlatchings just.
What deserves to be mentioned is; As shown in Figure 9, by the work period (duty cycle) of setting left eyeglass lens 31 and right eye eyeglass 32, make left eyeglass lens 31 close between 32 unlatchings of right eye eyeglass; Or right eye eyeglass 32 closes between left eyeglass lens 31 opens, also exist one change-over time t
2(T * 10% just) is at t change-over time
2In be to close images of left and right eyes eyeglass 31,32 simultaneously, and change-over time t
2Be to be synchronized with the left eye picture of Fig. 2 and t overlapping time of right eye picture
o, therefore, t overlapping time of display screen 212 switching displayed left eye pictures and right eye picture
oBe corresponding conversion time t
2Make the images of left and right eyes eyeglass 31,32 of shutter glasses 22 to close simultaneously; So hang wear shutter glasses 22 the user at this moment between the interval temporarily can't see display screen 212, solve the influence of (cross-talk) phenomenon of crosstalking that holographic display device 21 is produced whereby for the 3D visual effect when switching left eye picture and right eye picture.
In addition; Because signal generator 213 is to produce synchronous control signal according to the picture synchronization signal; And shutter glasses 22 is three parameters (initial order, first is set information and second and the set information) actions that comprise according to synchronous control signal; So when different holographic display devices uses the picture synchronization signal of different display characteristics; Each parameter of synchronous control signal also can correspondingly change, and makes shutter glasses 22 can be applicable to the holographic display device 21 of the picture synchronization signal of different display characteristics.
In sum, the initiatively fast gate-type stereo-image displaying system of the present invention, device, glasses and control method can solve holographic display device 21 in the influence of switching (cross-talk) phenomenon of crosstalking that left eye picture and right eye picture produced.Moreover, by the design of holographic display device 21, make shutter glasses 22 can be applicable to the holographic display device 21 of the picture synchronization signal that uses different display characteristics, so can reach the object of the invention really with shutter glasses 22.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Though the present invention discloses as above with preferred embodiment; Yet be not in order to limit the present invention; Anyly be familiar with the professional and technical personnel; In not breaking away from technical scheme scope of the present invention; When the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be not break away from technical scheme content of the present invention;, all still belong in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present invention.
