An electronic apparatus includes unit circuits provided with electronic
devices, data lines connected to the unit circuits, a first output device
to output, as a first output, a current or a voltage corresponding to an
externally supplied data signal, a second output device to output, as a
second output, a current or a voltage corresponding to the magnitude of
the first output, and a selection supply device to select one of or both
the first output from the first output device and the second output from
the second output device and to supply the selected output to the data
line. With this configuration, the image reproducibility in a
low-luminance/low-grayscale display area of a display apparatus using EL
devices is enhanced.
