ABSTRACT:
A liquid crystal driver circuit is equipped with a memory circuit that temporarily stores inputted image data, a first selector circuit that successively selects image data of multiple channels that are read from the memory circuit and outputs the same in a time-divided manner, a digital/analog conversion circuit that converts the image data output in a time-divided manner from the first selector circuit into analog image signals, an amplification circuit that amplifies the analog image signals obtained by the digital/analog conversion circuit, and a second selector circuit that successively selects a plurality of output terminals and distributes the analog image signals amplified by the amplification circuit in a time-divided manner to the plurality of output terminals.
