Embodiment
The utility model is to implement like this:
In Fig. 1 to Fig. 6, a kind of infrared active-shutter formula 3D glasses system is made up of infrared synchronous signals coded transmitter and 3D glasses.Infrared synchronous signals coded transmitter functional block diagram as shown in Figure 1.Described infrared synchronous signals coded transmitter is by the photoelectricity input circuit that is coupled, and MCU microprocessor and infrared transmitter are formed.Described photoelectricity coupling input circuit converts the stereotelevision of input or the synchronizing signal of other three-dimensional playback equipment output to the correspondent voltage signal by photoelectrical coupler, is input to the test side of MCU.Such benefit is that external unit and infrared synchronous signals coded transmitter are isolated on circuit fully, avoids electrostatic high-pressure to disturb and other electromagnetic interference (EMI), has improved the stability and the reliability of work.Described MCU microprocessor carries out numerical coding by certain form to synchronizing signal, and carries out carrier modulation according to the synchronizing signal of photoelectricity coupled circuit input, exports infrared transmitter then to, has realized the numerical coding transmission of synchronizing signal.
The MCU microprocessor to the numerical coding sequential of synchronizing signal as shown in Figure 2.Negative edge and rising edge in synchronizing signal carry out digital coding, then above-mentioned coding are carried out carrier modulation rear drive infrared light emission pipe emission infrared synchronous signals.Because having adopted digital coding, carrier frequency can be 38KHz or other frequencies that general telepilot adopts, and also can not be subjected to the interference of telepilot.
Digitally coded bit stream data structure is led sign indicating number+device code and forms+attribute code by rising as shown in Figure 3.
Rise and to lead sign indicating number: be used to start shutter glasses synchronizing signal receiving circuit, form by the pilot pulse of the blank spaces sign indicating number+1 1P pulsewidth of the starting impulse+1 2P pulsewidth of 1 4P pulsewidth.
Device code: by every bit all is that totally 8 bit of 3P pulsewidth form.Be used to identify the pairing of stereoscopic display screen and shutter glasses,, cooperate the glasses of a plurality of identical device sign indicating numbers to use simultaneously so that under same environment, can realize a three-dimensional display to distinguish different equipment.Guaranteed non-interfering work between contiguous distinct device sign indicating number identical device, can work simultaneously but non-interference such as several identical in amusement arcade stereo game machines.
Attribute code: be used to distinguish the rising edge and the negative edge of synchronizing signal, form by 1 bit.
For the synchronizing signal code length that makes the distinct device sign indicating number keeps identical, thereby do not influence the locking phase of shutter glasses, the coding of single bit position adopts the duty complementary method, i.e. each bit position employing is wide but the mode dutycycle complementation is distinguished bit0 and bit1.The logic state of Bit0 and Bit1 is distinguished and is specially: rise and lead after the pilot pulse last in the sign indicating number, when the blank code of 2P+1P pulsewidth occurring at interval, promptly be expressed as Bit0; Otherwise when the blank code+2P pulsewidth that 1P at interval occurs the time, promptly be expressed as Bit1;
As can be seen from Figure 3, the width of whole coded signal is 34P.In order not disturb the use of normal remote control, must make 34P＜9Ms (a yard width is led in rising of telepilot), so 1 benchmark pulsewidth (1P) must be less than 0.26mS.
The communications protocol that device code is reset as shown in Figure 4.In order to match the device code that three-dimensional display and 3D glasses are set after dispatching from the factory at equipment again automatically, adopt communications protocol: stipulate that a fixed equipment sign indicating number is for being provided with identification code (for example 0x00) as Fig. 4, when need carry out device code when resetting, first is provided with identification code (0x00) along sending one earlier synchronously the infrared synchronous signals coded transmitter, follows at the next one synchronously along sending the device code of upgrading.The 3D glasses receive first synchronously along send over identification code (0x00) is set after, ensuing one is preserved along the new device code that sends over synchronously, thereby has realized having upgraded device code synchronously with stereoscopic display device.Described 3D glasses are as shown in Figure 5: by frame, and shutter LCD lens, compositions such as reception control circuit and power supply.
Described 3D glasses are each a slice shutter LCD lens about being provided with on the frame, and is provided with the infrared ray receive window on framework, about respectively be provided with the leg of spectacles that can Gong wear, and be used to place the inner chamber body of circuit board and battery.
Described reception control circuit functional block diagram is as shown in Figure 6: by the infrared ray receiving demodulation circuit, and synchronization signal decoder, parameter recognition and memory module, digital phase-locked loop frequency takes place and the phase control module, LCD sequential generation module, the LCD driving circuit is formed.
The ultra-weak electronic signal that the infrared ray receiving demodulation circuit receives infrared ray sensor amplifies and demodulation restores digitally coded synchronizing signal, sends into synchronization signal decoder.Synchronization signal decoder decodes the rising edge or the negative edge signal of synchronizing signal according to the infrared synchronous signals coded transmitter to the coded system of synchronizing signal, gives parameter recognition and memory module.Parameter recognition and memory module go out the frequency of synchronizing signal and phase value according to the period measurement of synchronizing signal rising edge and negative edge and it are saved in the synchronization parameter storer, so that press storing value asynchronous operation initiatively when lossing signal.The time-delay feature of LCD takes place to combine according to the parameter in the synchronization parameter storer with the phase control module in digital phase-locked loop frequency, initiatively go out frequency and the consistent waveform control signal of phase place with stereoscopic display screen frame preface stereo-picture such as stereotelevision, send LCD sequential generation module to.LCD sequential generation module produces suitable timing waveform according to time and the voltage characteristic of shutter LCD, give shutter LCD driving circuit, thereby realize that the switching of shutter LCD and the frame preface time-division stereo-picture of stereoscopic display screen keep synchronous opening and closing, make people's right and left eyes see image respectively with the left-right frames image synchronization of stereo-picture, thereby make the people produce stereoscopic sensation.Simultaneously by after adopting the method, even the of short duration synchronizing signal of losing the infrared synchronous signals coded transmitter, glasses are synchronous working normally still, and phenomenon asynchronous or that glimmer can not take place.
The above, it only is the preferred embodiment of a kind of infrared active-shutter formula of the utility model 3D glasses system, be not that technical scope of the present utility model is imposed any restrictions, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model above any trickle modification, equivalent variations and modification that embodiment did.
