Description
Technical field
The utility model relates to a kind of glasses, is specifically related to a kind of anaglyph spectacles that is used for producing at the image of watching display device stereoscopic visual effect.
Background technology
Why we mankind can see three-dimensional scenery, be that just left eye can only be seen the scenery of left eye because our eyes can independently be seen thing separately, and right eye can only be seen the scenery of right eye.Because two have spacing about us, cause two visual angle that fine distinction is arranged, and such difference can allow two scenery of seeing individually displacements a little.And the difference of left eye and eye image is called parallax, and our brain is very cleverly with two image co-registration, and the stereoscopic visual effect that produces the sense of having living space is in brain.In daily life, when we watch TV or computer monitor, because screen has only one, and we have two eyes, if the image that has stereoscopic vision just must allow images of left and right eyes see independently separates separately, just can pass through anaglyph spectacles this moment, allows this parallax continue to show on screen.Send three-dimensional signal (left eye-right eye-left eye-right eye-continuous in regular turn repetition alternate with each other) to screen by control IC, and send sync signal simultaneously to anaglyph spectacles, make it switch left-and right-eye images synchronously, promptly left eye is seen this scene of seeing of left eye, and right eye is seen this scene of seeing of right eye.
At present the anaglyph spectacles that generally uses is one and penetrates liquid crystal lens, by the control of circuit to the liquid crystal glasses open and close, opens that can to control eyeglass black entirely, so that cover a glance image; It is transparent that eyeglass can be controlled in the pass, so that another image of seeing to another this soon.Anaglyph spectacles just can the mimic actual situation, makes the continuous Alternation Display of images of left and right eyes picture on screen, and cooperates anaglyph spectacles synchronously, adds the physiological property that human eye vision persists, and just can see real stereo-picture.As disclosed a kind of wireless anaglyph spectacles among the Chinese utility model patent CN2890978, the after-frame that preceding frame is arranged and engage with preceding frame, the after-frame two ends are hinged with a leg of spectacles respectively, a battery case is installed in each leg of spectacles, its internal fixation has button cell, be made of the power supply of button cell opens the light the switch contact at switch contact on the leg of spectacles end and after-frame two ends, the switch contact respectively with button cell just, negative pole links to each other with wiring board, switch contact when leg of spectacles is opened on the leg of spectacles end contacts respectively with the switch contact at after-frame two ends, button cell is powered to total system, when leg of spectacles is crooked, the total system outage.The upper fixed of preceding frame central part has an infrared signal receiving demodulation module, the left and right sides of preceding frame and after-frame is symmetrically installed with the switch LCD panel, be fixed with wiring board between preceding frame and the after-frame, professional chip is arranged on the wiring board, and button cell is infrared signal receiving demodulation module, professional chip, wiring board and the power supply of switch LCD panel.
Yet in use there is bigger defective in above-mentioned anaglyph spectacles, utilize the folding of leg of spectacles to come the confession of control system to cut off the power supply, the setting of this switch has caused the increase of leg of spectacles volume, use inconvenient, also attractive in appearance inadequately, and the switch dependability of this physical construction is poor, and frequent use causes loose contact even switch to damage easily, and serviceable life is shorter.
Summary of the invention
The utility model purpose provides a kind of anaglyph spectacles, by the improvement of structure, has improved the reliability of using, and prolonged serviceable life, and structure is attractive in appearance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of anaglyph spectacles, comprise a spectacle-frame body, be provided with the circuit that is used to control liquid crystal lens in the described spectacle-frame body, described circuit comprises power supply, synchronizing signal processing module, control module and light valve driver module, described synchronizing signal processing module is connected with control module respectively with the light valve driver module, also is provided with the induction testing circuit, and described induction testing circuit is electrically connected with control module.
In the technique scheme, be provided with microprocessor in the described control module.
In the technique scheme, described induction testing circuit is used to respond to the position relation of anaglyph spectacles and human body, to determine user mode, can adopt one of multiple sensing mode.
Optimized technical scheme, described induction testing circuit is a resistance sensing circuit, two pins that are used for the resistance sensing are positioned at the position that contacts with user's body surface on the spectacle-frame body.
For example, a circuit board assemblies and an electric battery are installed in the spectacle-frame body, electric battery is connected with circuit board assemblies.Circuit board assemblies comprises driving circuit, power circuit and has the inductive control circuit of microcontroller chip that the inductive control circuit output terminal is connected with microcontroller chip and control Driver Circuit driving LCD panel is closed and opened; Power circuit is connected with electric battery, inductive control circuit and driving circuit and electric power is provided.Only need sensor circuit just to begin to wake up for voltage signal entire circuit of microcontroller during use and enter duty from sleep state, in case voltage signal disappears, microcontroller cuts out driving circuit, receiving circuit, change sleep state over to, almost do not have power consumption, realized the low-power consumption of entire circuit.
During use, produce current potential by human body contact induction switch, compare by comparing it with the set potential that is provided with, whether the CPU in the notice synchronizing signal processing module starts working.When starting working, the synchronizing signal processing module receives synchronizing signal and drives LCD panel work, control module is handled the signal that the synchronizing signal processing module receives, obtain synchronous switching signal, by amplification, obtain driving the signal of left and right LCD panel open and close, the work of driving switch LCD panel to switching signal, make the continuous Alternation Display of left and right picture on LCD panel, thereby see stereo-picture.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, because the utility model by being provided with inductive switch between the power supply of anaglyph spectacles and the synchronizing signal processing module, makes that the work of anaglyph spectacles is more reliable, the life-span and the structure that have prolonged use are attractive in appearance.
2, the utility model is simple in structure, and is easy to use, is fit to promote the use of.
