Background technology
Fast gate-type 3D glasses in the common 3D glasses system; Generally comprise picture frame and mirror leg; Wherein picture frame comprises two liquid crystal lens and signal receiver; This signal receiver is used to receive the wireless signal (for example Infrared Video Signal, wireless audio signal) that the 3D TV is launched, and wireless signal is decoded, and therefrom decodes video and audio synchronous signal; Circuit board and battery have been encapsulated in the mirror leg; This circuit board comprises circuit structures such as central processing and control element (PCE) (for example central processing element CPU or microcontroller MCU etc.), video signal driver and audio-signal-driven circuit, and it can carry out synchronous processing with video synchronization signal and the audio synchronous signal that signal receiver decodes, and sends to respectively in right and left eyes liquid crystal lens and the audio output device (for example earphone); Thereby the video of right and left eyes liquid crystal lens institute perception is carried out the high speed switching; So that for the user presents relief video, export for the user provides with the audio frequency of audio video synchronization through audio output device simultaneously, satisfy the relief audiovisual demand of user.
But also there is following shortcoming in the fast gate-type 3D glasses in this traditional 3D glasses system: this traditional fast gate-type 3D glasses are the video of switching right and left eye perception fast, also promptly realizes the function of opening and closing; Thereby the generation stereoscopic sensation, but and reckon without between user and the 3D TV because the distance of distance and the visual impact of generation; If also be that the user is closer apart from the 3D TV; Then tend to because light is too strong, and feel dazzling, viewing time is long more; Vision is got over easy fatigue; Unfavorable to health, therefore, if the lightness of the fast gate-type 3D glasses of adjusting that can be manual (also being the transmittance of liquid crystal lens) then will greatly make things convenient for user's demand in the use.
Therefore need a kind of 3D glasses system that comprise fast gate-type 3D glasses that can the manual adjustments transmittance and control method.
In addition; The various fast gate-type 3D glasses that can realize video and audio sync output that occur at present at audio output, are just simply realized the output of audio frequency through audio output devices such as earphones; Lack corresponding audio control apparatus (the for example adjusting of audio frequency size, the switch of sound signal etc.); If this moment, also there be (for example in family or the cinema) in the sound of 3D TV, user distance 3D TV is also far away, then may be asynchronous with the sound of 3D TV owing to the sound of audio output devices such as earphone, perhaps watch environment (for example in family or the cinema) to exist echo that reverberation takes place; Influence user's tonequality demand; Therefore, if manual control audio output unit (also promptly regulating the switch of audio frequency size, control audio) then will greatly make things convenient for user's demand in the use.
Therefore also need a kind of 3D glasses system that comprise the fast gate-type 3D glasses that manual control audio is exported and control method.
In addition, present fast gate-type 3D glasses because its start-up control module generally is divided into two parts (for example battery and circuit board), are separately positioned in two legs of spectacles; The fast gate-type 3D glasses of this structure, its leg of spectacles all is designed to two-layer folder hollow structure, and its inner space is used for cabling; So the volume of this glasses is generally all bigger, weight is heavier, and constriction is stronger when wearing for a long time; Structure is also comparatively complicated, in the transmission course electric energy loss also bigger, cost is higher.
If therefore the structure of the fast gate-type 3D glasses in the 3D glasses system is more integrated, structure is simpler, with the use that greatly makes things convenient for practical field.
