), the supramolecular complex that can mix various colloid systems and obtain to merge.
In wet layer, because the orientation of supramolecular complex on substrate, molecule has good order along a direction.When solvent evaporation, it demonstrates the energy that is more conducive to molecule, thereby forms three-dimensional crystalline structure.
Sandwich construction comprises the two-layer at least layer that obtains by said method.Herein, the optical axis of independent anisotropic layer normally altogether to.Because light can take place and reflect in the certain spectral of polaroid in the interference effect in the thin layer.The thickness of layer and be chosen to make a polarized component of light to be reflected effectively by this structure to the refractive index of each polarization direction, and other polarized component is passed through no reflection events ground.Absorb light, a hypersorption material layer is set in the direction of propagation of the outside surface upper edge radiation of metacoxal plate through sandwich construction.Eliminate the dazzle that comes from the display metacoxal plate like this and improved visual contrast.In addition, this design can obtain black in image.
Because owing to the anisotropic of height makes the layer very thin (less than 100nm) of acquisition, and the number of plies can minimum (as 3), so this sandwich construction can be placed on the inside of LC display.
Can also obtain the polaroid of prebasal plate according to the above-mentioned technology that has corresponding selection to original material (form LLC or have the material blends of suitable absorption spectrum).And this polaroid can also be placed on the inside of display.
The inside of display all functions layer is placed the size that has reduced display and has been improved durability, has also simplified the manufacture process of display.
In addition, the method for the present invention of making the anisotropic layer is based on the real part that depends on refractive index and the angle ellipsoid of imaginary part is this fact of plate-like.The shape that changes refractive index imaginary part ellipsoid has been improved the parameter and the angular characteristics thereof of polaroid significantly.In display, use this polaroid the visual angle can be increased to 180 °.
