3-dimensional image display device and display method thereof
First Claim
1. A 3-dimensional image display device comprising:
- a backlight unit;
a barrier panel disposed above the backlight unit and comprising a plurality of unit barriers which selectively blocks light passing therethrough;
a lenticular lens array disposed above the barrier panel and comprising a plurality of lenticular lenses, wherein each of the lenticular lenses has a principal point;
a liquid crystal panel disposed above the lenticular lens array and configured to display an image, the barrier panel disposed between the backlight unit and the liquid crystal panel;
an eye tracking sensor which detects a position of eyes of a viewer and a distance between the principal point of the lenticular lenses and the eyes of the viewer; and
a controller which controls the backlight unit, the barrier panel and the liquid crystal panel based on an output of the eye tracking sensor,wherein the controller turns on and off the unit barriers such that light emitted from the backlight unit and passed through the barrier panel passes through the principal point of the lenticular lenses to apply a right-eye image to a right eye of the viewer and apply a left-eye image to a left eye of the viewer.

Abstract
A 3-dimensional image display device includes: a backlight unit; a barrier panel above the backlight unit and including unit barriers which selectively blocks light; a lenticular lens array above the barrier panel and including lenticular lenses, each having a principal point; a liquid crystal panel above the lenticular lens array; an eye tracking sensor which detects a position of eyes of a viewer and a distance between the principal point of the lenticular lenses and the eyes; and a controller which controls the backlight unit, the barrier panel and the liquid crystal panel based on an output of the eye tracking sensor, where the controller turns on and off the unit barriers such that light passes through the principal point of the lenticular lenses to apply a right-eye image to a right eye of the viewer and apply a left-eye image to a left eye of the viewer.

12. A display method of a 3-dimensional image display device comprising a liquid crystal panel, a barrier panel behind the liquid crystal panel, a lenticular lens array between the liquid crystal panel and the barrier panel, a backlight unit behind the barrier panel, an eye tracking sensor and a controller, the method comprising:
-
detecting a position of a left eye and right eye of a viewer and a distance between the left and right eyes of the viewer using the eye tracking sensor; operating unit barriers of the barrier panel as a right-eye barrier and a left-eye barrier by the controller based on an output of the eye tracking sensor; turning on the right-eye barrier when the a right-eye image is displayed by the liquid crystal panel such that the right-eye image is applied to the right eye of the viewer by light emitted from the backlight unit and passed through the barrier panel passing through principal points of lenticular lenses in the lenticular lens array; and turning on the left-eye barrier when the a left-eye image is displayed by the liquid crystal panel to apply the left-eye image to a left eye of the viewer by light emitted from the backlight unit and passed through the barrier panel passing through the principal points of the lenticular lenses in the lenticular lens array. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
