Abstract
Disclosed is a display device. The display device comprises an electroluminescence display panel including a fingerprint recognition area in a display area including a plurality of pixels on a substrate, an ultrasonic fingerprint sensor, under a rear side of the electroluminescence display panel, arranged corresponding to the fingerprint recognition area, and a support substrate, between the electroluminescence display panel and the ultrasonic fingerprint sensor, configured to support the electroluminescence display panel and the ultrasonic fingerprint sensor.
Claims27
A display device comprising:
- an electroluminescence display panel, the electroluminescence display panel including a display area and a fingerprint recognition area in the display area, the display area including a plurality of pixels;
- an ultrasonic fingerprint sensor under the electroluminescence display panel, the ultrasonic fingerprint sensor overlapping the fingerprint recognition area of the electroluminescence display panel;
- and
- a support substrate between the electroluminescence display panel and the ultrasonic fingerprint sensor, the support substrate configured to support the electroluminescence display panel and the ultrasonic fingerprint sensor.
A display device comprising:
- an electroluminescence display panel;
- a fingerprint sensor disposed under the electroluminescence display panel;
- and
- a light-shield support substrate between the electroluminescence display panel and the fingerprint sensor, the light-shield support substrate configured to absorb external light that is transmitted through the electroluminescence display panel and reflected by the fingerprint sensor.
A display device including:
- an electroluminescence display panel comprising a plurality of pixels on a flexible substrate, the flexible substrate having a Young's modulus in a range from 1.5 GPa to 3 GPa;
- an ultrasonic fingerprint sensor under the electroluminescence display panel;
- a cured adhesive member that bonds the ultrasonic fingerprint sensor to the electroluminescence display panel;
- and
- a light-shield support substrate positioned between the electroluminescence display panel and the ultrasonic fingerprint sensor, the light-shield support substrate configured to absorb at least a portion of external light that passes through the electroluminescence display panel and configured to reduce a flatness degradation of the electroluminescence display panel due to a stress exerted by the cured adhesive member that bonds the ultrasonic fingerprint sensor to the electroluminescence display panel.
