A system for transmitting data based on serial communication, which allows the number of slave apparatuses connectable to one master apparatus to be increased, includes a master apparatus configured to generate an input data packet including first data, second data, and control data, and a slave apparatus group consisting of a plurality of slave apparatuses connected in a daisy-chain manner to the master apparatus, wherein each of the slave apparatuses determines first identification information (ID) using bits included in the first data, extracts second ID from the second data, and controls a target device using the control data when the first ID and the second ID match.

Apparatus and method for transmitting data based on serial communication

A hybrid dimming control device, which prevents image quality degradation during local dimming of a backlight unit, includes an analysis circuit configured to determine a type of dimming data for controlling the local dimming of a light source included in a backlight unit by analyzing the dimming data, a pulse width modulation (PWM) dimming control circuit configured to control the local dimming of the light source by a PWM method when the type of the dimming data is a first type, and an active dimming control circuit configured to convert some bits of the dimming data into an analog signal and control the local dimming of the light source using the analog signal when the type of the dimming data is a second type.

Hybrid dimming control device and hybrid dimming control method

A system for controlling backlight unit capable of reducing a time difference between an image displayed on a display panel and local dimming of the backlight unit, includes a plurality of dimming control devices configured to receive an input data packet including dimming data, and control local dimming of a light source, which is included in a region assigned in advance in a backlight unit, using the dimming data, a plurality of gate lines configured to electrically connect a predetermined number of dimming control devices and configured to be sequentially driven according to a row driving method, and a micro controller unit configured to generate a gate control signal for driving the plurality of gate lines and the input data packet.
