DISPLAY APPARATUS
First Claim
1. A display apparatus comprising:
- a display panel that displays an image using a first light;
a light guide part positioned at a front side of the display panel to emit a second light different from the first light and guide the second light;
a backlight unit positioned at a rear side of the display panel to provide the first light to the display panel;
an image information collecting part that photographs the second light emitted from the light guide part to output an image information; and
a processing part that processes the image information to generate a coordinate value of a position at which an object provided on the light guide plate is positioned, wherein the backlight unit comprises;
a plurality of first light sources that emit the first light; and
a diffusion plate disposed between the display panel and the first light sources to diffuse the first light emitted from the first light sources, the diffusion plate being provided with a plurality of openings formed therethrough, wherein the image information collecting part comprises;
a plurality of lenses that receive the second light emitted from the light guide plate, the lenses being provided to correspond to the openings in one-to-one correspondence;
a plurality of optical fiber groups that guide the second light provided through the lenses, ends of the optical fiber groups being accommodated in the openings, respectively; and
at least one camera disposed below the diffusion plate to photograph the second light guided by the optical fiber groups and output the image information.

Abstract
A display apparatus includes a display panel that displays an image using a first light, a light guide part positioned at a front side of the display panel, a backlight unit, an image information collecting part, and a processing part. The light guide part emits a second light different from the first light and guide the second light, and the backlight unit is positioned at a rear side of the display panel to provide the first light to the display panel. The image information collecting part photographs the light emitted from the light guide part to output image information. The processing part processes the image information to generate a coordinate value of a position at which an object provided on the light guide plate is positioned.
