Embodiment three
The present embodiment provides what the display device in a kind of peep-proof film based in embodiment one or embodiment two was realized to prevent
Peep method, which comprises
Step S101, control electrophoresis particle move to the side far from black matrix", make peep-proof film in peep-proof state.
Step S102, control electrophoresis particle move to the side for being close to black matrix", make peep-proof film in sharing state.
In a particular application, electrophoresis particle can be made in the effect of electric field by way of applying electric field to electrophoresis particle
The direction of motion of lower movement, electrophoresis particle is related with charge polarity entrained by direction of an electric field and electrophoresis particle, direction of an electric field with
The movement under force direction of positive charge is identical, contrary with the movement under force of negative electrical charge.
For example, for display device shown in Figure 4 and 5, when electrophoresis particle 12 carries positive charge, to make peep-proof film be in
Peep-proof state then needs to apply the electric field for being directed toward side of the peep-proof film far from black matrix" 5 by black matrix" 5 to electrophoresis particle 12,
So that electrophoresis particle 12 is moved to the side far from black matrix" 5, to make peep-proof film in state is shared, then needs to electrophoresis particle 12
Apply the electric field for being directed toward black matrix" 5 far from the side of black matrix" 5 by peep-proof film, electrophoresis particle 12 is made to move to abutting black
The side of matrix 5;Similarly, it when electrophoresis particle 12 carries negative electrical charge, to make peep-proof film in peep-proof state, then needs to electrophoresis grain
Son 12 applies the electric field for being directed toward black matrix" 5 far from the side of black matrix" 5 by peep-proof film, moves to electrophoresis particle 12 separate
The side of black matrix" 5 then needs to apply to be directed toward by black matrix" 5 to electrophoresis particle 12 and prevent to make peep-proof film in state is shared
The electric field for peeping side of the film far from black matrix" 5 makes electrophoresis particle 12 move to the side for being close to black matrix" 5.
For display device shown in fig. 6, when electrophoresis particle 12 carries positive charge, to make peep-proof film be in peep-proof state,
It then needs to apply negative voltage to electrode 31, apply positive voltage to electrode 32 or do not apply voltage, electrophoresis particle 12 is made to gather electricity
Around pole 31, to make peep-proof film in state is shared, then need to apply positive voltage to electrode 31 or not applying voltage, applied to electrode 32
Add negative voltage, gather electrophoresis particle 12 far from electrode 31 and is close to the side of black matrix", gathers around electrode 32;Together
Reason, when electrophoresis particle 12 carries negative electrical charge, to make peep-proof film in peep-proof state, then need to apply to electrode 31 positive voltage, to
Electrode 32 applies negative voltage or does not apply voltage, gathers electrophoresis particle 12 around electrode 31, to make peep-proof film in sharing
State then needs to apply negative voltage to electrode 31 or does not apply voltage, applies positive voltage to electrode 32, gathers electrophoresis particle 12
Far from electrode 31 and it is close to the side of black matrix", gathers around electrode 32.
The embodiment of the present invention gathers electrophoresis particle far from black by controlling electrophoresis particle movement in above-mentioned peep-proof film
The side of matrix or the side for being close to black matrix", so as to simply and effectively realize the peep-proof function of peep-proof film with share function
Energy.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
