Abstract
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.
