Embodiment as shown in Figure 1, use the utility model, at first gather that synchronizing signal is amplified by wireless transmission after infrared, by crystal glasses reception, amplification and circuits for triggering with through liquid crystal light valve and increase frequently the back supplemental light source and handle and obtain not flicker effect from TV.
As shown in Figure 2, wireless synchronization transmission circuit: 1. transmitting terminal: the synchronous square-wave signal by source of synchronising signal sends, by wireless transmission modulation module IC1, generate one group of modulation wave signal, amplify through one stage signal again, by infrarede emitting diode emission output; 2. receiving terminal: receive the control head modulating wave that is received is imported preposition amplification, handle through detection, shaping again, the output synchronizing signal.
The source of synchronizing signal can be divided into two parts: 1. introduce full television video frequency signal from the video input and output port, and by a row separation to composite video signal, and the identification of parity field signal, produce one group of synchronizing signal; Perhaps, 2. photoelectricity coupling circuit: utilize the station symbol and the fixation mark thereof of sign that television set itself produces, character, TV station to be " photoelectric synchronous signal source ", from then on receive photosignal in the mark by light electric transducer.Aim at various marks on the television screen with light electric transducer, comprise TV station's station symbol, fixed signal, the tab character that television set itself produces, also can around video screen, pick up the photoelectric synchronous signal Anywhere, amplify through photosignal, the identification of strange, even field signal with separate the selection of three-dimensional and non-stereoeffect, export the opening and closing that drive liquid crystal glasses by timesharing, realize three-dimensional stereo effect.
Fig. 3, Fig. 4 obtain, separate, launch and be introduced vision signal.
Shown in Figure 5, flicker liquid crystal light valve glasses not: 1. backlight and drive circuit: the blank screen that brings to human eye when closing for overcoming liquid crystal is mended frequently light filling and for making light backlight evenly distribution on liquid crystal light valve, the utility model has been chosen flat luminous, and the opening and closing of light source are synchronous with the open and close of liquid crystal light valve.Under the situation of the twilight sunset slope of strictness control back light photoelectricity saturation curves and light source, can reach in theory and mend frequently to liquid crystal light valve that 25Hz and simple eye flicker frequency rise to 25Hz+25Hz, reach the purpose that overcomes or weaken and glimmer.2. light adjustable control circuit: for overcoming because the variation of extraneous light power, it is consistent with extraneous light to reach light filling light weak intensity, three groups of photoelectric control circuits on the synchronous control signal of backlight, by red, green, blue three color light detection light sensor (photodiode) the strong and weak color separation of light source to external world carries out opto-electronic conversion, height according to voltage after the opto-electronic conversion is regulated red respectively, green, blue three looks are gone here and there the automatic and adjustable potentiometer and are carried out dividing potential drop, reach control to the back light input voltage, realize backlight red, green, the strong and weak automatic and adjustable of blue-light source, thereby make the color of back supplemental light and intensity and surround lighting roughly the same, just improve flicker frequency, the imperceptible colourity of eyes is strong and weak to be changed and allow.
