Abstract
A display device includes a display unit including a plurality of pixels arranged in a first direction and a second direction intersecting the first direction and a lens unit disposed on the display unit and configured to refract an image output from the display unit. The lens unit includes a lens array including a plurality of lenses each extending at an acute angle with respect to the second direction and a liquid crystal layer disposed on the lens array. The liquid crystal layer includes liquid crystal molecules oriented in substantially the same direction as an extension direction of the lenses.
Claims12
A display device comprising:
- a display unit including a plurality of pixels arranged in a first direction and a second direction perpendicular to the first direction;
- and
- a lens unit disposed on the display unit and configured to refract an image output from the display unit,
- wherein the lens unit includes:
- a lens array including a plurality of lenses each extending at an acute angle with respect to the second direction;
- and
- a liquid crystal layer disposed on the lens array,
- wherein the display device is configured to operate in a two dimensional (2D) mode and a three dimensional (3D) mode,
- wherein the liquid crystal layer includes liquid crystal molecules oriented such that a long axis of the liquid crystal molecules is slanted substantially at the acute angle with respect to the second direction, when the display device is operated in the 2D mode,
- wherein an absolute value of a difference between a refractive index of the liquid crystal layer and a refractive index of the lenses is less than 0.01 when the display device is operated in the 2D mode,
- wherein light of the image output is incident on the liquid crystal layer after passing through the plurality of lenses.
