Abstract
A display panel drive device includes: a ring counter circuit that includes a first ring counter having a plurality of flipflops connected in cascade, configured to operate in synchronization with a first clock signal with a first-stage one of the plurality of flipflops being set by an initial signal, and outputs signals using outputs of the plurality of flipflops; a shift register having a plurality of flipflops connected in cascade, configured to operate in synchronization with a second clock signal lower in frequency than the first clock signal with a first-stage one of the plurality of flipflops being set by the initial signal; and an output section configured to perform a logical operation between one of outputs of the ring counter circuit and one of outputs of the shift register, to generate a scanning line drive signal for a display panel.
