Patent ID: 11963273
Assignee: LX SEMICON CO., LTD.
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 9:
10. A display device comprising:
a plurality of light emitting diodes (LEDs) disposed in a panel;
a switch circuit configured to adjust a current supplied to the LEDs;
an LED driving circuit configured to receive a pulse width modulation (PWM) signal to adjust turn-on and turn-off periods of the switch circuit and a pulse amplitude modulation (PAM) signal to adjust current intensity of the switch circuit and to change a driving current of the LEDs; and
a microcontroller unit (MCU) configured to transmit an LED driving control signal to the LED driving circuit so that the LED driving circuit performs hybrid driving in which PWM driving and PAM driving are mixed,
wherein the LED driving control signal independently sets supply timing of the driving current transmitted to the LEDs for each current channel.
