Abstract: A backlight unit includes a light source module including a first connection pin and a second connection pin electrically connected to the first connection pin, a power converter which provides a driving voltage to the light source module, a connector which receives a first enable signal via a first signal line and provides a second enable signal via a second signal line and a driving circuit which controls a generation of the driving voltage from the power converter in response to the second enable signal. When the connector is electrically connected to the first and second connection pins, the first enable signal is transmitted to the first connection pin via the first signal line and the connector, and the second enable signal from the second connection pin is provided to the driving circuit via the connector and the second signal line.

Abstract: A display apparatus includes a housing having a pillar shape, a plurality of monitors, and a driving unit received in the housing and providing driving signals to the plurality of monitors. Each of the plurality of monitors displays an image through its front surface and back surface and includes side surfaces connecting the front surface and the back surface. One side surface of the side surfaces of each of the plurality of monitors is coupled to the housing. A thickness of each of the plurality of monitors decreases as a distance from the housing increases.

Abstract: A liquid crystal display device includes an upper substrate, a lower substrate including a data line and a gate line insulated from the data line, a liquid crystal layer between the lower substrate and the upper substrate, a current sensing unit which detects a data current based on a data signal applied to the data line so as to detect a change in a liquid crystal capacitance of the liquid crystal layer, a rectifying amplifier which rectifies or amplifies the detected data current so as to generate and output a rectified signal, a pulse generator which generates a sensing pulse by comparing the rectified signal with a reference voltage, and a duty width detector which detects a duty width of the sensing pulse generated by the pulse generator where the reference voltage is set based on a voltage difference between data signals successively applied to the data line.

Abstract: A display apparatus includes a display panel having fan-out lines, data lines, a first dummy line, and a second dummy line. The fan-out lines are sequentially disposed along a first direction. The data lines are connected to the fan-out lines at first through nodes. The first dummy line is connected to one of the nodes. The second dummy line is connected to another of the nodes. A first data driver is configured to output data voltages to some of the fan-out lines based on a data signal. A second data driver is configured to output voltages to other fan-out lines based on the data signal. A timing controller is configured to compensate the data signal based on a voltage of nodes that the dummy lines are connected to.
