Capacitive load driving circuit including input selection circuit and liquid crystal display device using the driving circuit |
摘要 |
A capacitative load driving circuit is provided in a liquid crystal display device and has an input selection circuit having a wide and effective voltage range of an input signal. The driving circuit changes over through source or emitter followers formed by two types of conductivity, for detecting as to whether or not a potential of the input signal is in an input voltage range of a differential amplifier circuit constituting a voltage follower after selecting at least one input signal through any of source or emitter followers.
