Abstract: An apparatus for driving a liquid crystal display includes a picture quality improving unit that extracts a brightness component from first data, analyzes the brightness using the extracted brightness component, and generates second data having a contrast in accordance with the analyzed brightness. The contrast of the second data is extended from that of the first data. A timing controller rearranges the second data to supply the second data to a data driver. A backlight supplies the light to a liquid crystal panel in accordance with a driving current. An inverter supplies the driving current to the backlight.

Abstract: A projection lens system that has a compact configuration and is capable of correcting a color aberration. In the system, first and second lenses have a weak refractive power, respectively, and a third lens has a strong positive refractive power. A fourth lens corrects an aberration generated by the third lens, and a fifth lens has a negative refractive power. A diffractive optical element is formed on at least one among the surface of the first to fifth lenses. A color aberration and spherical aberration is corrected with the diffractive optical element, so that a high resolution can be realized without increasing the number of lenses and the manufacturing cost can be reduced.
