DISPLAY APPARATUS AND DRIVING APPARATUS FOR DRIVING BACK LIGHT THEREOF

摘要

PURPOSE: A display apparatus and a drive circuit apparatus for driving backlight arranged on the same are provided to reduce the number of peripheral components by minimizing the size of a backlight driving circuit. CONSTITUTION: A switching part(L1,S1) is switched in order to supply drive power to a backlight. A signal synthesizing part synthesizes a current control signal and a dimming signal. The signal synthesizing part outputs a synthesized signal. The current control signal controls a current flowing in the backlight. The dimming signal controls dimming of the backlight. A driving part(161) outputs the driving signal to the switching part. The driving part dimming-operates the backlight based on a combined signal.
