Description
Technical field
The utility model relates to a kind of grating, particularly relates to a kind of grating that can produce different visual experiences in different visual angles.
Background technology
Common automatically controlled grating, it is configured with two, one is the electric-controlled mechanical masking device, two is the electrically-controlled liquid crystal display equipment, its function is all simple control light and penetrates and cover, with electrically-controlled liquid crystal display equipment commonly used at present is example, it is to place to have the anisotropic nematic liquid crystal layer of dielectric between two conducting glass substrates, has transparent stripe electrode on the conducting glass substrate therein, then continuous electrode on another conducting glass substrate, utilize the viscosity of liquid crystal molecule, elasticity and galvanic couple polarity, when no extra electric field, the liquid crystal molecule direction aligns according to both alignment layers, and the liquid crystal molecule that the deflection polarity of incident light is arranged changes, and produces the variation of optical path difference, added-time outside electric field, the liquid crystal molecule direction is arranged with the extra electric field direction, and the deflection polarity of incident light is not changed thereby does not have optical path difference and changes, and pressing from both sides up and down just can have bright on display with polaroid, the contrast of dark portion.Yet this kind device all can be identical at picture that any visual angle is seen, display can't have special-effect with the variation at visual angle, in the use thereby be restricted.
The utility model content
The purpose of this utility model provides a kind of grating with visible change function, and expectation can produce different visual experiences in different visual angles, to be applied in the light shield of display or tool special-effect by this design.
For reaching aforementioned purpose, a kind of grating of the utility model design with visible change function, it comprises an electric control scatter-type panel and and has the light guide plate of single specific light direction, this light guide plate comprises a sensitive side and a bright dipping side, this electric control scatter-type panel is positioned at the bright dipping side of light guide plate, this electric control scatter-type panel comprises two substrate, high molecule liquid crystal layers with transparent conductive film, and is distributed in the macromolecular structure and the liquid crystal molecule of the orientating function of high molecule liquid crystal interlayer.
Thus, this light guide plate has single specific light direction, only allows the light of single specific direction to penetrate.This electric control scatter-type panel comprises a high molecule liquid crystal layer and is distributed in the macromolecular structure and the liquid crystal molecule of the orientating function of high molecule liquid crystal interlayer.For upward angle of visibility, during no impressed voltage, it between each liquid crystal molecule aeolotropic, when incident light shines, because the refractive index of the macromolecular structure of liquid crystal molecule and orientating function does not match, interface at both can produce scattering, light can't penetrate electric control scatter-type panel, be applied to and present dark portion on the display, when impressed voltage, liquid crystal molecule is arranged in vertical with transparency carrier with direction of an electric field, the arrange in pairs or groups light guide plate of single specific light direction, this moment liquid crystal molecule and orientating function the refractive index match increase of macromolecular structure, incident light part scattered portion penetrates electric control scatter-type panel, the light that penetrates is applied to and presents highlights on the display, so upward angle of visibility presents usual black pattern (Normally blackmode); For downwards angle of visibility, under the alive outside situation, light penetrated the supreme view directions of panel along the direction of advancing originally, was applied to present dark portion on the display.When not having impressed voltage, because of the scatter-type panel presents scattering state, the faint light that as seen downwards angle of visibility scatters, be applied to and present highlights on the display, make downwards angle of visibility present usual white mode (Normally whitemode), therefore, at different visual angles, can produce different visual experiences.
