Electronic apparatus, electronic system, and driving method for electronic apparatus
Abstract:
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.
