Classification: CPC H  G | IPC H

Claim 15:
16. A display device comprising:
light emitting diodes (LEDs) connected to a plurality of current channels and configured to transmit light to a panel; and
a microcontroller unit (MCU) configured to transmit a serial clock signal and a local dimming signal to an LED driving circuit in order to control operation of the LED driving circuit controlling driving currents of the LEDs, wherein
the MCU is configured to control differently control timings of driving currents of the LEDs of the plurality of current channels, and
the MCU is configured to generate an LED driving control signal, which controls a duty ratio of a pulse width modulation (PWM) signal to adjust a size of the driving currents of the LEDs and controls a pulse amplitude modulation (PAM) signal to adjust the size of the driving currents of the LEDs, and deliver the LED driving control signal to the LED driving circuit.
