The display system of the application includes light collimation module and light view angle switch module, and light collimation module is sent
Most of is the light of collimating status, light view angle switch module be then mainly used in by display system wide viewing angle and narrow viewing angle it
Between switch, and then realize peep-proof pattern and non-peep-proof pattern.
Light view angle switch module includes two conducting films, and is provided with diffusion structure in the gap between two conducting films
Film and electrooptical material, the refractive index of diffusion structure film is n1, and the refractive index of electrooptical material is one in n2 or n3, and n2 or n3
It is individual equal with n1.Apply voltage on two conducting films, the refractive index of electrooptical material can be changed, and n3 is changed into from n2, or
N2 is changed into from n3.As refractive index n1=n2, the switching module is equal to high transparency film, it then follows the light extraction of light colimated light system point
Cloth；As refractive index n1 ≠ n3, the emergent light of light collimation module can be scattered and spread by diffusion structure film, and light is regarded
Angle becomes big.Wherein Δ n (n1-n3 absolute values) is bigger, and it is bigger that light visual angle is spread, and effect is more obvious.
Optical texture is simple in above-mentioned display system, and less energy intensive, and need not increase the quantity of light source, can be achieved with
Peep-proof is shown.
The preferred embodiment of the application is the foregoing is only, the application is not limited to, for the skill of this area
For art personnel, the application can have various modifications and variations.It is all within spirit herein and principle, made any repair
Change, equivalent substitution, improvement etc., should be included within the protection domain of the application.
