Abstract
A backlight pixel driving circuit includes an interface unit configured to receive dimming data, a storage unit configured to store the received dimming data, a controller configured to drive a backlight pixel based on the dimming data, and an analog circuit block, wherein the controller generates a channel enable signal synchronized with a pulse width modulation signal and controls the on-off of the analog circuit block using the channel enable signal. Accordingly, an effect of reducing current consumption may be further increased as an analog circuit block itself of a light-emitting diode (LED) driving circuit is dynamically turned on and off.
