Abstract:
Disclosed is an AMOLED driving device. The AMOLED driving device includes a fingerprint identification circuit and a detection identification circuit. The fingerprint identification circuit includes multiple fingerprint identification units provided in an active area. Each fingerprint identification unit corresponds to one pixel unit. The detection identification circuit is used to sense and compensate a current flowing through an OLED element and to analyze and process a signal outputted by the fingerprint identification circuit. The AMOLED driving device can reduce a bezel area of the display device and expands the active area.
