Abstract:
A touch device and a display device including the same are provided. The touch device includes: a first substrate; a second substrate facing the first substrate, and disposed to be spaced apart from the first substrate by a predetermined interval; a third substrate connecting first end portions of the first and second substrates to each other, and propagating an ultrasonic signal propagated along the first substrate to the second substrate; a plurality of first ultrasonic transducers connected to second portions facing the first end portions in the first substrate, and propagating an ultrasonic signal to the first substrate; and a plurality of second ultrasonic transducers connected to the second portions facing the first end portions in the second substrate, and receiving an ultrasonic signal propagated along the second substrate, wherein a touch point may be detected based on signal intensity variations of ultrasonic signals received by the second ultrasonic transducers.
