Display apparatus drive circuit having plurality of cascade connnected drive ICs

摘要

To prevent a timing shift of a clock and data supplied to a driver IC. A driver 1011 includes a phase adjustment circuit 201 for receiving via input terminals a clock and data outputted from a controller 103, latching received data with the clock adjusted to a 50-percent duty ratio, and outputting as phase-adjusted signals the data having the latched data further latched by synchronizing it with a delay clock having the duty-ratio-adjusted clock delayed by (pi/2) and the clock of the 50-percent duty ratio.
