摘要 |
A selection-addressing-type liquid crystal display selectively addresses a signal line of a pixel unit using groups of three selectors of a selector circuit in a time-division manner. A level converter level shifts selector pulses having a voltage swing corresponding to the external-circuit power supply to selector pulses having a voltage swing corresponding to the internal-circuit power supply. In a non-display region in partial display mode, the level converter is deactivated under the control of a control signal to reduce direct current consumption therein. |
