Control the "on" position of the flexible screen 20.
Specifically, as shown in figure 3, above-mentioned flexible screen 20 include the first base layer 21, the first conductive layer 22, mixed layer 23,
Second conductive layer 24 and the second base layer 25, wherein the mixed layer 23 includes the mixing of cholesteric liquid crystal phase and macromolecular structure
Thing, and for controlling the chiral dope of cholesteric liquid crystal phase pitch, the cholesteric liquid crystal phase is with showing black because of scattering
Or the second stable state of color is write in the first stable state of liquid crystal blackboard background color and reflection；When the cholesteric liquid crystal phase is in the
During one stable state, the visible ray for being incident to the cholesteric liquid crystal phase shows black or liquid crystal blackboard background face in transmissive state
Color；After the cholesteric liquid crystal phase is because of action of writing local compression, when being in the second stable state after allowing liquid crystal molecule to flow,
Be incident to the cholesteric liquid crystal phase shows person's handwriting in color visible reflective condition, and the visible ray passes sequentially through institute
State the first base layer 21, the first conductive layer 22, cholesteric liquid crystal phase and the second conductive layer 24 to be incident on the second base layer 25.
In the present embodiment, above-mentioned cholesteric liquid crystal phase has bistable state, leads in the first conductive layer 22 and the second conductive layer 24
After electricity, cholesteric liquid crystal phase will be presented the first stable state；After the first base layer 21 is pressurized so that the cholesterol just to pressurized position
Phase liquid crystal is presented the second stable state.Rotation pitch of the above-mentioned chiral dope specifically for adjustment cholesteric liquid crystal phase, it is solid so as to control gallbladder
The wavelength of alcohol phase liquid crystal reflection light wave, so as to change the color that flexible screen shows.
For example, in order to make when writing cholesteric liquid crystal phase in the second stable state, visible reflectance can be made, needs to add
The wavelength of appropriate chiral dope control cholesteric liquid crystal phase Bragg reflecting lights is within visible-range.For example, lead first
When electric layer 22 and 24 power-on voltage of the second conductive layer reach preset value, first will be presented when cholesteric liquid crystal phase is under pressure steady
State, it is seen that light passes through the first base layer 21 and the first conductive layer 22 incides cholesteric liquid crystal phase in transmissive state, now shows
The color of substrate 26.The second stable state, each liquid crystal molecule in cholesteric liquid crystal phase will be presented when cholesteric liquid crystal phase is under pressure
Rotary shaft offset from perpendicular arrange parallel to substrate so that visible ray passes through the first base layer 21 and the first conductive layer
22 incide cholesteric liquid crystal phase in green reflective condition.Now user watches 21 white state of the first base layer, that is, go up
State flexible screen and could be arranged to green, so as to reach the effect of the green word of black matrix.Handwriting be other colors also can, only need change
The content of percentage ratio chiral dope.
