It covers glue and drying and is formed and above-mentioned define structure 320.
It is arranged below with liquid crystal layer subregion 310 (containing liquid crystal molecule 20 and pigment 10) in first electrode 400 and second
For between electrode 500, the principle of discoloration, which is described in detail, to be realized to liquid crystal layer subregion：
In some embodiments of the invention, electric field and not formed electricity are formed between first electrode 400 and second electrode 500
When field, the liquid crystal molecule deflection state in liquid crystal layer subregion 310 is different, so as to lead to shell light under above two state
Transmitance change.And pigment molecular reflects the complementation of absorbed light by the light for absorbing specific wavelength in light
The primary colors of color, therefore shell entirety transmitance has change, and the variation of the visual effect (color) of shell entirety may be implemented.
Some specific embodiments according to the present invention, by liquid crystal molecule 20 have positive dielectric constant anisotropy for into
Row explanation：When liquid crystal layer subregion 310 is in OFF state, the light transmittance of liquid crystal layer subregion 310 can be 10~20%, when to the first electricity
When pole 400 and second electrode 500 apply voltage, i.e., when liquid crystal layer subregion 310 is in ON state, liquid crystal molecule 20 is according to being applied
Voltage rotates, at this moment, the liquid crystal molecule 20 of deflection can well-regulated rotation, and then when liquid crystal layer subregion 310 is in ON state,
The light transmittance of liquid crystal layer subregion 310 is higher, such as can be 20~40%.That is, the light transmittance of liquid crystal layer subregion 310 is by 10
~20% is increased to 20~40%.Thus, it is possible to which can enable shell integrally by application voltage has more bright visual effect.
Alternatively, other embodiments according to the present invention, liquid crystal molecule 20 also can have negative dielectric constant anisotropy.At this point,
Liquid crystal layer subregion 310 (does not apply voltage) when being in OFF state, shell light transmittance with higher, such as can be 20~40%.Liquid
When crystal layer subregion 310 is in ON state, shell can have lower light transmittance, such as can be 10~20%.It can also lead to as a result,
Application voltage is crossed, the apparent condition of shell is regulated and controled.
The pigment 10 of other embodiments according to the present invention, doping can have similar structure with liquid crystal molecule 20,
If the shape of liquid crystal molecule 20 and pigment 10 is rodlike.With reference to Fig. 5, liquid crystal layer subregion 310 (does not apply electricity when being in OFF state
Pressure), horizontal traverse state is all presented in liquid crystal molecule 20 and pigment 10, i.e. liquid crystal molecule 20 and the long axis direction of pigment 10 is parallel
In horizontal plane, the color of the extraneous shell seen is exactly the color that pigment 10 is presented, at this point, the light transmission of liquid crystal layer subregion 310
Rate is 10~20%.With reference to Fig. 6, when liquid crystal layer subregion 310 is in ON state (apply voltage), liquid crystal molecule 20 can be according to being applied
The voltage added will rotate, and the liquid crystal molecule 20 of deflection will drive the well-regulated rotation of pigment 10, i.e. pigment 10 itself exists
It will not independently deflect under electric field action, need to be deflected under the drive of liquid crystal molecule 20, liquid crystal molecule 20 and color
Plumbness is all presented in element 10, i.e. the long axis direction of liquid crystal molecule 20 and pigment 10 is each perpendicular to horizontal plane, at this point, extraneous seen
To the face of pigment 10 will become smaller, light transmittance can also become larger accordingly, and the light transmittance of liquid crystal layer subregion 310 is 20~40%,
To the lighter of the extraneous shell seen, i.e., the change of shade is realized under the control of different voltages, reaches view
Feel the variation in effect.Thus, it is possible to the light transmittance of liquid crystal layer subregion 310 is adjusted by the control of voltage, final letter
Just the variation multiplicity of realization shell visual effect, realizes the selection of various appearances, no replacement is required, and shell can obtain outside a variety of
Effect is seen, meets the needs of user individual, substantially increases the competitiveness of product in market.
