1. An organic light emitting diode (OLED) panel, comprising:
a substrate; and
a pixel on the substrate, the pixel including
a first OLED configured to emit a first light,
a first sensor including an organic photodiode and configured to absorb and detect the first light reflected or scattered by a biometric object,
a second OLED configured to emit a second light,
a first OLED driving transistor configured to drive the first OLED, and
a second OLED driving transistor configured to drive the second OLED,
wherein the first OLED and the first sensor are on a same plane, and
wherein at least one driving transistor of the first OLED driving transistor and second OLED driving transistor is between an OLED driven by the at least one driving transistor and the substrate.
