The first electrode 142 and second electrode 152 of the two sides of 130a and groove 130d can be grounded so that electric switchable optical structure
120 maintain that mist is presented.Therefore, in the flrst mode, misty groove 130a and ditch is presented in electric switchable optical structure 120
Slot 130d is separated by the first space D 1.Here, the measurement of spacing is with one of misty electric switchable optical structure 120
Groove right side edge to next mist electric switchable optical structure 120 groove right side edge distance.In other realities
It applies in example, spacing is also possible to the distance between the ditch groove center of the electric switchable optical structure 120 of two neighboring mist, or
The distance between groove left side edge.
In the present embodiment, groove 130a, groove 130b, groove 130c, groove 130d, groove 130e and groove 130f
First electrode 142 be applied voltage V1, voltage V2, voltage V3, voltage V4, voltage V5 and voltage V6 respectively.Groove 130a,
Groove 130b, groove 130c, groove 130d, groove 130e and groove 130f second electrode 152 be applied respectively voltage V7,
Voltage V8, voltage V9, voltage V10, voltage V11 and voltage V12.In order to make groove 130b, groove 130c, groove 130e and
Electric switchable optical structure 120 in groove 130f is at light transmission shape, the pressure difference of voltage V2 and voltage V8, voltage V3 and voltage V9
The pressure difference of pressure difference, the pressure difference of voltage V5 and voltage V11 and voltage V6 and voltage V12 needs to be greater than electric switchable optical structure
120 can be at the critical value of light transmission state.Illustrate by taking one of groove 130b as an example, if above-mentioned electricity switchable optical structure
120 can be 20 volts of pressure differences at the driving electric field of light transmission state, then it is 20 volts that voltage V2 and voltage V8 one of them, which can be amplitude,
Special alternating voltage and another one be 0 volt or is grounded.In addition, the pressure difference and voltage V4 and voltage of voltage V1 and voltage V7
The pressure difference of V10 needs to be less than electric switchable optical structure 120 can be at the critical value or voltage V1 of light transmission state, voltage V7, electricity
Pressure V4 and voltage V10 is 0 volt or ground connection, so as to be set to the electric switchable optical structure of groove 130a and groove 130d
120 maintain that mist is presented, and so invention is not limited thereto.
Under the second mode, as shown in Figure 1B, apply driving electric field in groove 130b, groove 130c, groove 130d with
And groove 130e, make the electric switchable optical structure for being set to groove 130b, groove 130c, groove 130d and groove 130e
120 are presented light transmission shape, and maintain the electric switchable optical structure 120 for being set to groove 130a and groove 130f that mist is presented.
Therefore, under the second mode, be set to groove 130a and groove 130f the misty electric switchable optical structure 120 of presentation that
This is separated by the second space D 2.
By Figure 1A and Figure 1B it is found that the first space D 1 is different from the second space D 2.That is, under different time,
It can be obtained by the adjustment of driving electric field with application, obtain different preventing peephole away from (i.e. misty electricity can be cut in different time
Change the spacing of optical texture 120).In some embodiments, the first space D 1 is, for example, to be greater than or equal to the second space D 2
150um, and it is less than or equal to 450um, the width W of groove 130 is, for example, to be greater than or equal to 1um, and be less than or equal to 7um, so
Invention is not limited thereto.User can adjust peep-proof device 10 appropriate according to the display to be arranged in pairs or groups of peep-proof device 10
Pitch-row, to avoid occurring moire fringes on display picture and influencing display quality.
Fig. 2 is the diagrammatic cross-section according to the peep-proof device of one embodiment of the invention under a drive mode.Referring to figure
