Abstract

A curved display apparatus providing an air touch input function including: a curved display including a concavely curved monitor to display a three-dimensional image; a three-dimensional filter unit having the same radius of curvature as the curved monitor and disposed in front of the curved monitor; a position input unit disposed in front of the three-dimensional filter unit and configured to detect a three-dimensional position according to a user'"'"'s non-touch motion in a predetermined sensing region; and an image control unit configured to control a three-dimensional image displayed on the curved monitor by transmitting position information sensed through position input unit to the curved display, wherein air touch input through a user'"'"'s non-touch motion is performed in a concave region of the curved display.

Claims

1. A curved display apparatus providing an air touch input function comprising:

a curved display including a concavely curved monitor to display a three-dimensional image;

a three-dimensional filter unit having the same radius of curvature as the curved monitor and disposed in front of the curved monitor;

a position input unit disposed in front of the three-dimensional filter unit and configured to detect a three-dimensional position according to a user'"'"'s non-touch motion in a predetermined sensing region; and

an image control unit configured to control a three-dimensional image displayed on the curved monitor by transmitting position information sensed through position input unit to the curved display,

wherein air touch input through a user'"'"'s non-touch motion is performed in a concave region of the curved display.

2. The curved display apparatus providing an air touch input function according to claim 1, wherein the position input unit includes an infrared sensor or an ultrasonic sensor configured to output a sensing signal upward from below or downward from above.

3. The curved display apparatus providing an air touch input function according to claim 1, wherein the sensing region includes a range extending forward from a concave surface of the curved monitor by a predetermined radius of curvature, a range extending in a longitudinal direction of the curved monitor, and a range extending in a height direction of the curved monitor.

4. The curved display apparatus providing an air touch input function according to claim 1, wherein the curved display further includes an interaction unit configured to be synchronized with the position information sensed through the position input unit and perform physical interaction.

5. The curved display apparatus providing an air touch input function according to claim 4, wherein the interaction unit includes a polymer-based haptic element or piezo element.

6. The curved display apparatus providing an air touch input function according to claim 1, wherein the three-dimensional filter unit includes a lenticular lens sheet.
