Curved touch display apparatus for providing tactile feedback and method thereof

Abstract

A curved touch display apparatus for providing tactile feedback is provided. The curved touch display comprises a curved screen, in which an image is displayed; and a projector including an infrared irradiator for irradiating infrared rays to the curved screen. An infrared camera photographs an infrared image reflected from the curved screen. An ultrasonic wave array module includes a plurality of ultrasonic wave generators which generate airborne ultrasonic waves. A controller determines a touched point on the curved screen based on the infrared image, and controls an operation of the ultrasonic wave array module to generate airborne ultrasonic waves directed to the touched point.
