DRIVE CIRCUIT DEVICE FOR DISPLAY DEVICE AND DISPLAY DEVICE USING THE DRIVE CIRCUIT DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the power consumption and an electromagnetic wave generation caused by propagating signals such as clock signals, data signals and control signals which propagate in a plurality of drive circuit devices. SOLUTION: The driving circuit device for display device driving a plurality of bus lines provided on a display substrate is characterized in that it is provided with a driver section (20) which receives propagating signals Sa that include at least either one of clock signals and control signals and generates driving signals for the bus lines and a gate section (22) which starts to output the signals Sa to a trailing stage drive circuit device in synchronism with the signal receiving start timing of the device after a prescribed time from the receipt of the signals Sa. Since the propagating signals are not propagated to the trailing stage of the drive circuit device that is receiving the signals, the power consumption and the generation of electromagnetic waves are reduced.
