A backlight module includes a pixel driver integrated circuit (PDIC) configured to generate a switch control signal and a pulse control signal, the pulse control signal including timing information and dimming data, a pixel integrated circuit (PIC) configured to generate a pulse modulation signal based on the pulse control signal, a switch group configured to transfer a driving voltage based on the switch control signal, and a backlight unit (BLU) including a first end connected to the switch group and a second end connected to the PIC, the BLU configured to emit light on a panel based on the driving voltage and the pulse modulation signal, where the PDIC is configured to generate the switch control signal and the pulse control signal such that a light emitting diode emits light at a time point at which a pixel of the panel operates.

Backlight module, display device, and method for driving backlight unit

A backlight system includes a plurality of pixel ICs respectively including a plurality of channels connected to a plurality of LEDs and that control the LEDs to be turned on and off through the channels, and a driver IC connected to the pixel ICs and that supplies a data signal to each of the pixel ICs. The pixel ICs include a first pixel IC connected to first LEDs and a second pixel IC connected to second LEDs. The first pixel IC turns the first LEDs on or off in a first order based on first control data included in the data signal, and the second pixel IC turns the second LEDs on or off in a second order different from the first order based on second control data included in the data signal.

Backlight system

A power transmitting apparatus may include: an input device including a motor shaft selectively connected to an engine, a first input shaft selectively connected to the motor shaft and provided with at least one input gear fixedly disposed thereon, and a second input shaft disposed without rotational interference with the first input shaft and provided with at least one input gear fixedly disposed thereon; a motor/generator disposed on the motor shaft of the input device and operated as a motor or a generator; a selectively connecting device adapted to selectively connect the motor shaft of the input device to the engine, the first input shaft, or the second input shaft; and a speed output device changing torque input from the first and second input shafts of the input device and outputting the changed torque.
