A touch display module utilizing touch recognition by ultrasound includes display unit on substrate, barrier layer on other side of the substrate, and an ultrasound fingerprint sensing unit on the barrier layer. An acoustic impedance of the display unit, the barrier layer, and the ultrasonic fingerprint sensing unit are not all the same, and the differences in impedances enable recognition of touches by analysis of reflected ultrasound. The disclosure also provides an electronic device using the touch display module.
