A display device can include a timing controller; a level shifter including a signal input circuit to receive a first clock signal and a second clock signal, a driving mode conversion circuit to self-generate one or more mode signals based on the first and second clock signals for adjusting a driving mode, and a signal output circuit to generate a plurality of scan clock signals based on the one or more mode signals, the first and second clock signals; a shift register configured to generate a scan signal based on the plurality of scan clock signals; and a display panel configured to display an image based on the scan signal. Also, the level shifter is configured to in response to a width of a pulse of the first clock signal being greater than a threshold value, sequentially output a pulse for each of the plurality of scan clock signals.

A backlight unit, with a parallel configuration of plural lamps, having improved reliability is disclosed. The backlight unit driver includes: first and second lamps connected parallel to each other; a DC/AC inversion portion inverting a DC voltage into an AC voltage to apply the AC voltage to the lamps; a transformer transforming the AC voltage from the DC/AC inversion portion; a positive polarity AC signal compensator compensating an electric current difference between the first and second lamps using positive polarity AC signals from the first and second lamps; and a negative polarity AC signal compensator compensating the electric current difference between the first and second lamps using negative polarity AC signals from the first and second lamps.

Driver for backlight unit

A lamp-connection socket for a lamp for a display device, and a backlight unit and LCD device using the same are disclosed. The lamp-connection socket includes a body that includes a lamp receiving portion that supports an end portion of a lamp; a first terminal that extends from within the body to the outside of the body to receive a potential for driving the lamp; a balance device arranged within the body and electrically connected to the first terminal; and a clip arranged in the body that releasably clamps a lamp electrode at the end of the lamp, the clip electrically connected to the balance device.
