Abstract
A drive circuit device for a display device which drives a plurality of source bus lines provided on a display panel includes a driver unit that receives a clock signal, a data signal and a control signal, sequentially fetches the data signal, and generates drive signals for the source bus lines in accordance to the fetched data signal. The device further includes a gate unit that, after elapse of specified time from the reception of the driver unit, and at a timing when a rear-stage drive circuit device starts receiving, starts outputting of a propagation signal including at least one of the clock signal, data signal and control signal to the rear-stage drive circuit device. Consequently, the power consumption required for supplying these signals and the generated amount of electromagnetic waves resulting from the signal supply can be suppressed.
