Abstract

Provided are a luminous member, a method of driving the luminous member, a non-volatile memory device, a sensor, a method of driving the sensor, and a display apparatus. The luminous member includes a first electrode; a second electrode facing the first electrode; an emission layer, which is disposed on a main surface of the first electrode and emits light by power applied between the first electrode and the second electrode; and a ferrodielectric layer disposed between the emission layer and the second electrode, wherein AC power applied to the luminous member is controlled based on polarity or magnitude of a residual polarization generated in the ferrodielectric layer, thereby adjusting emission characteristics of the emission layer.
