Abstract
A display device includes a flexible display panel, an ultrasonic fingerprint sensor which is disposed below a rear surface of an active area of the flexible display panel and has a first thickness and a first width, a cushion structure which is disposed below the rear surface of the flexible display panel, surrounds the periphery of the ultrasonic fingerprint sensor, and has a second thickness larger than the first thickness, and a circuit board which is electrically connected to the ultrasonic fingerprint sensor and has a second width larger than the first width.
Claims18
A display device, comprising:
- a flexible display panel including an active area for emitting light;
- an ultrasonic fingerprint sensor disposed below the active area of the flexible display panel, the ultrasonic fingerprint sensor spaced apart from a rear surface of the flexible display panel in a first direction;
- a cushion structure disposed below the flexible display panel, and disposed adjacent the ultrasonic fingerprint sensor in a second direction different from the first direction;
- and
- a circuit board electrically connected to the ultrasonic fingerprint sensor, wherein the cushion structure includes a heat dissipation layer;
- and wherein the circuit board contacts and is electrically connected with the heat dissipation layer.
