1. A display apparatus, comprising:
- a position sensor to sense an eye position of a user;
a controller to set a virtual viewing window corresponding to the sensed eye position of the user and to provide a control signal to control generating of a directional light toward the virtual viewing window; and
a light generator to generate the directional light toward the virtual window based on the control signal.

Abstract
A display apparatus that may generate a high density light field image is provided. The display apparatus may identify an eye position of a user and set a virtual viewing window around the eye of the user. The display apparatus may generate a directional light corresponding to the viewing window and generate a high density light field image.

17. A display apparatus, comprising:
-
a position sensor to sense an eye position of a user using at least one of a visible light band camera, an infrared camera, and a depth camera; a controller to set a size of a virtual viewing window and to determine a position of the virtual viewing window based on the eye position of the user and a size of the eye, and to provide a control signal to control generating of a directional light toward the virtual viewing window; and a light generator including a backlight providing a standard light source, a variable slit to modulate the standard light source to a point light source at a predetermined position, and a lens to generate, based on the control signal, the directional light by refracting the point light source toward the virtual viewing window. - View Dependent Claims (18, 19)

20. A display method comprising:
-
continuously tracing a pupil position of an eye of a viewer of a display; dynamically setting a virtual viewing window of the display to correspond to the continuously traced pupil position; and generating an image in the virtual viewing window while not generating an image in portions of the display that do not correspond to the virtual viewing window.
