1. A backlight driver, comprising:
a pixel driver configured to generate a plurality of gate signals applied to a plurality of gate lines and generate a plurality of source signals applied to a plurality of source lines; and
a plurality of pixel circuits connected to the pixel driver through the plurality of gate lines and the plurality of source lines, and configured to generate a plurality of driving currents based on the plurality of gate signals and the plurality of source signals,
wherein the pixel driver is configured to
generate, while the plurality of gate signals are generated, a non-overlap interval between activation intervals of two adjacent gate signals, all of the plurality of gate signals being deactivated during the non-overlap interval, and
generate, while the plurality of source signals are generated, a high-impedance interval exclusively in the non-overlap interval, at least some of the plurality of source signals having a high-impedance state during the high-impedance interval.
