1. A wearable device, comprising:
a power circuit;
a touch display driver integration circuit, coupled to the power circuit, the touch display driver integration circuit performing touch functionality and display driving functionality;
an under-display fingerprint recognition circuit, coupled to the power circuit, the under-display fingerprint recognition circuit performing under-display fingerprint recognition functionality; and
an organic light-emitting diode (OLED), coupled to the power circuit, the OLED performing illumination and display,
wherein the power circuit comprises: a first pin for providing an analog voltage source to the touch display driver integration circuit; a second pin for providing a digital voltage source to the touch display driver integration circuit and the under-display fingerprint recognition circuit; and a third pin for providing a first OLED voltage to the OLED and the under-display fingerprint recognition circuit, wherein the under-display fingerprint recognition circuit uses the first OLED voltage as an analog voltage source.
