A display device includes a first electrode, a second electrode, a third electrode, a lyophobic layer, a first liquid, and a second liquid, where the lyophobic layer is lyophobic to the second liquid. A method of driving the display device includes: providing a first potential difference between the first electrode and the third electrode to thereby cause the first liquid to begin moving toward the second electrode; providing a second potential difference between the second electrode and the third electrode while reducing the first potential difference to thereby cause the first liquid to move toward the first electrode; and removing the second potential difference to thereby cause the first liquid to slow down in its movement toward the first electrode or to stop in its movement toward the first electrode.

In a power supply device whose safety is improved, a backlight assembly and a display apparatus having thereof, the power supply device includes a printed circuit board, a transformer and a securing cover. The transformer is disposed on the printed circuit board to change a first input voltage into a second voltage, and outputs the second voltage. The securing cover covers a portion where the second voltage is outputted. Accordingly, when a securing cover covers a portion where the high voltage is outputted, the safety of the power supply can be enhanced.

A light generating device includes a brightness detector. The brightness detector extracts a brightness data from an image data. The light generating device compensates the uniformity of a white light whenever the image data that is greater than a reference gray scale is input through the brightness detector. Thus, the light generating device may compensate the uniformity of the white light in real time, so that a display apparatus employing the light generating device may improve a high-quality image.
