BACKLIGHT ASSEMBLY, DISPLAY APPARATUS HAVING THE SAME AND CONTROL METHOD THEREOF

摘要

A backlight assembly with a light source unit, includes: a drive signal generator which generates a switching drive signal on the basis of a predetermined drive frequency and a feedback power fed back from the light source unit; a switching unit which outputs a power to the light source unit in response to the switching drive signal; and a controller which decreases the drive frequency if the feedback power is higher than a predetermined critical value.
