Driver for active matrix type liquid crystal display device |
摘要 |
A driver for an active matrix type liquid crystal display device includes a CMOS transfer switch group capable of arbitrarily selecting a drive reference voltage, a CMOS transfer switch for transferring a drive reference voltage selected by the CMOS transfer switch group to a driver output terminal, and an operational amplifier connected in the form of a voltage follower. The liquid crystal driver output voltage quickly reaches an arbitrarily selected drive reference voltage, and a stable voltage coinciding with the reference voltage can be applied to the liquid crystal display device.
