Patent ID: 7750981

Claim:
An autostereoscopic display comprising: a display panel receiving an image signal from a controller, forming an image, and including pixels and an inactive area between the pixels; a polarizer polarizing light emitted from the display panel to a first polarization; a polarization switch selectively converting the light with the first polarization into light with a second polarization in response to the electrical control of a polarization switching controller; a 2D-3D selection controller; a first electro-optical birefringent layer having a crystal optical axis that is changed by an electrical control of the selection controller and comprising a plurality of first lenticular lenses separated by a predetermined pitch; and a second electro-optical birefringent layer having a crystal optical axis that is changed by the electrical control of the selection controller and comprising a plurality of second lenticular lenses that have the same pitch as the first lenticular lenses and are parallel to the first lenticular lenses and are shifted by half the pitch from the first lenticular lenses.
