The Part No. that this example adopts Hamamatsu Photonics company to provide is that the S6560 product is as above-mentioned optic angle degree sensor and illuminance sensor.
The alternative means of the sensor can be: the combination of any other photodetector, if can sense intensity of illumination and incident angle, also can be used as angle probe and illuminance inductor, can respond to visible light and ultraviolet photodiode for two, its combination can be used as the substitute of S6560 detector.Detector to the position sensor sensitivity can substitute two photodiodes in angle probe and the illuminance sensor.Operational amplifier can be converted to voltage signal with each current signal, and the analog to digital converter in the microcontroller is a digital signal with all analog signal conversion, and therefore the direction of light source and the intensity of illumination are calculated.Another selection is, the voltage by each photodiode can directly measure, and do not need the conversion of such electric current and voltage.Angle probe also can be substituted by manual adjustments control device such as pot.
Select the synoptic diagram of the liquid crystal stick that needs shading according to incident angle θ referring to Fig. 7
Above-mentioned angle and optical sensor and liquid crystal lens are contained on the sunglasses, the sensor normal is overlapped with the lens normal, after human eye is put on this sunglasses, just form geostationary coordinate between human eye and liquid crystal lens and the sensor, at this moment an immobile liquid crystal bar piece on all corresponding eyeglass of each visual angle line of human eye.Cpu chip calculates intense light source and human eye line behind the incident angle θ with respect to normal on the eyeglass according to the value of sensor signal (Ia-Ib)/(Ia+Ib), can select the liquid crystal stick n corresponding with this θ angle sight line.
As shown in Figure 7: human eye is L to the distance of eyeglass, and the width of stick is W on the eyeglass, a shared N stick on the eyeglass, the angle of n stick and normal direction is θ, so cpu chip can calculate n according to angle θ, this stick is exactly should be by the liquid crystal stick of light shading.
The angle of light characteristic curve of Fig. 8 liquid crystal lens:, can calculate high light incident angle θ according to angle sensor signal value (Ia-Ib)/(Ia+Ib) by this curve.
Cpu chip promptly applies the control voltage that can make its blank screen to this stick after having selected and need having carried out liquid crystal stick n that light blocks.
Add DC voltage to LCDs and can cause ion to move, lower the life-span of LCDs, so this example is an AC controling signal to each liquid crystal stick loading.
Alternation control voltage on the liquid crystal stick also can be realized by transferring methods such as dutycycle, amplitude modulation.
To be this routine cpu chip apply the oscillogram of control voltage to each liquid crystal stick to Figure 10, is carried in voltage signal on each electrode and is frequency, dutycycle, square-wave voltage that the spoke value is identical, and this figure has showed and is carried in the signal sequence on the single electrode in the eyeglass.
Waveform a is the signal waveform that is carried on the shared public electrode of all liquid crystal sticks.
The stick that loads the b waveform does not have phase shift with respect to waveform a, and voltage on its control electrode and the voltage on the public pole do not have difference, so effective voltage value is 0, thereby this stick can not present weakening of transmitance.
The stick that loads the c waveform has produced less phase shift with respect to waveform a, and the effective voltage value that is added on this liquid crystal stick control electrode and the public electrode forms less alternating voltage, and the control voltage that is added on the liquid crystal stick is increased to some extent, has reduced its light transmission rate.
The stick of the d waveform that loads has produced big phase shift with respect to waveform a, the effective voltage value that is added on this liquid crystal stick control electrode and the public electrode forms big alternating voltage, it is more that the control voltage that is added on the liquid crystal stick is increased, and reduced the light transmission rate of stick more.
The stick that loads the e waveform exists maximum to differ with respect to waveform a, voltage on its control electrode and the voltage on the public pole have 180 degree phase shifts, it is maximum that the alternating voltage that its effective voltage value forms reaches, to exchange control voltage enough big when this, can make the liquid crystal stick that loads this voltage become the black area, reach the effect that light blocks.
So in 0-180 degree scopes, change the signal phase be added in liquid crystal stick control electrode, but just light transmission rate of this stick of stepless control.
As a same reason, when controller applies described average control voltage to all liquid crystal sticks, change the effective voltage value that is added on all liquid crystal sticks by the phase place in-migration that makes alternating voltage on the alternating voltage that all liquid crystal stick control electrodes apply produces with respect to public electrode, when average light illumination raises, the phase shift that produces increases, and effective voltage value is improved, when average light illumination reduces, the phase shift that produces reduces, and effective voltage value is reduced.
Add DC voltage to LCDs and can cause ion to move, lower the life-span of LCDs, so this example is an AC controling signal to each liquid crystal stick loading.
Above-mentioned only is to have enumerated a kind of driven waveform, and this square-wave signal is easy to produce by " opening " " pass " control to direct current signal, also can adopt the driving voltage of other form that can produce same control effect certainly.
Fig. 9 is the operating process synoptic diagram of this controller.
Controller detects incident angle of light θ transducing signal and intensity of illumination transducing signal by angular transducer and optical sensor.
Under the normal conditions, cpu chip is 0 to the signal difference voltage that each liquid crystal stick loads;
When cpu chip calculates environment average light illumination according to illuminance transducing signal (Ia+Ib), earlier Ia+Ib amount and the illuminance threshold value of setting are compared, if be lower than this threshold value, then do not produce average control voltage, if be higher than this threshold value, promptly the power generation one average control voltage according to this average light illumination is loaded on the control electrode of all liquid crystal sticks, control the average light transmitance of whole liquid crystal lens, environment average light illumination is strong more, average control voltage is high more, the average light transmitance of whole liquid crystal lens is just low more, otherwise just high more.
When cpu chip calculates intense light source and the human eye line incident angle θ with respect to normal on eyeglass according to the value of angle sensor signal (Ia-Ib)/(Ia+Ib), promptly calculating with above-cited method needs the liquid crystal of shading stick n, with it as center shading stick and it is applied enough big control voltage make it become shading black area (as described a waveform and e waveform before its public electrode and control electrode are loaded respectively).
Select liquid crystal stick n+1, the liquid crystal stick n+2 adjacent, liquid crystal stick n-1, liquid crystal stick n-2 as transition shading stick simultaneously with center shading stick n, and relatively the center antiglare module applies the control voltage that reduces one by one to them and (loads foregoing d waveform as feeding crystal bar piece n ± 1, feeding crystal bar piece n ± 2 load foregoing c waveform), form the zone of transition that the light and shade gradient type changes.
Fig. 5 is the control program FB(flow block) of microprocessor cpu chip,
Initialization: to the distance L of this cpu chip input human eye to described eyeglass, vertical width of described all subregion is W, and this W value is all identical to all subregions, and in order to reflect the input voltage threshold value of illuminance critical value, whether this critical value decision cpu chip starts
Set: the normal direction the when people is at eye level overlaps with the normal direction of eyeglass, described normal is as the X-axis of coordinate axis, the intersection point of this normal and eyeglass is a true origin, to do vertical line from described true origin in the eyeglass, this vertical line is the Y-axis of coordinate axis, and the subregion at this true origin place is numbered, it is numbered zero, be positioned at the above and following subregion of described X-axis and be marked with positive sign and negative sign respectively, distinguish serial number again
When illuminance is lower than its critical value, when photocurrent Ia+Ib was lower than the work threshold value that described cpu chip sets, this cpu chip did not start, and all electrodes of described eyeglass do not have any control voltage signal input;
The illuminance critical value that is higher than setting when the illuminance of sunshine, during work threshold value that photocurrent Ia+Ib sets greater than described cpu chip, this cpu chip starts, to square wave voltage signal that frequency, dutycycle are all set of public electrode output of described liquid crystal lens, execution in step 4 simultaneously;
Cpu chip judges whether photocurrent Ia equals photocurrent Ib:
If: Ia=Ib, what then described sensor received is the incident light of vertical incidence, incident angle is zero, this cpu chip make each control electrode on the described liquid crystal lens import respectively one be added in described public electrode on the identical control signal of square waveform voltage, this control signal and square wave voltage signal phase differential 180 degree of transporting on the described public electrode, and amplitude-frequency is all identical with dutycycle, makes that transmitance is identical on the liquid crystal lens all subregion, thereby the transmittance of each horizontal stick distributes the same;
If: Ia ≠ Ib, this cpu chip is the sequence number n of that sub regions of θ with respect to incident angle, described θ angle be line between the human eye and the sun with respect to the angle of described X-axis, described sequence number n is exactly the numbering of that subregion at the intersection point place of this line and liquid crystal lens
Tan θ=nW/L, and θ ∝ (Ia-Ib)/(Ia+Ib), and be that subregion of n applies the control voltage signal to sequence number, there is the maximal phase potential difference in described control voltage signal with respect to the square wave voltage signal that is added on the described public electrode, make the magnitude of voltage that is added on the described eyeglass n work song zone reach maximum, input voltage and light transmittance curve according to liquid crystal lens make the transmitance in this n work song zone drop to minimum, produce blank screen, block high light, also apply the voltage signal that relative n work song zone phase differential reduces to some extent simultaneously to n+1 work song zone adjacent and n-1 work song zone with n work song zone, apply relative n work song zone phase differential to n+2 work song zone and n-2 work song zone and reduce more voltage signal, even the control voltage that is carried on these transition sticks reduces one by one, form the light and shade zone of transition that the transmittance gradient type changes.
Reduce the width W of every liquid crystal stick, increase the quantity of liquid crystal lens level to the liquid crystal stick, can improve the resolution of control, but also reduced the width of blank screen liquid crystal stick, so after choosing the pairing liquid crystal stick in θ angle as the center antiglare module, also optional one or several liquid crystal stick that is adjacent is altogether as the center antiglare module, applying high voltage jointly makes them become shading region, to increase the width of shading black area, center, the above selects the liquid crystal stick adjacent with shading black area, center as transition shading stick for another example.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; every foundation technical spirit of the present utility model all still belongs to the protection domain of technical solutions of the utility model to any simple modification, equivalent variations and modification that above embodiment did.
