    Abstract: A liquid crystal display and a method of driving the same are disclosed. The liquid crystal display includes a liquid crystal display panel for displaying an image, an external light sensing unit for sensing an illuminance of external light around the liquid crystal display panel, a backlight unit whose an output luminance is controlled by an adjustment dimming signal, and a gamma curve adjusting circuit for modulating digital video data or varying resistances of variable resistors constituting a gamma resistor string based on the illuminance of external light or according to a relative maximum white luminance based on the adjustment dimming signal, so as to uniformly keep a relative brightness of the input image a user perceives irrespective of changes in the illuminance of external light.

    Abstract: A display device includes a substrate; an organic light-emissive layer disposed on the substrate; and a cathode electrode layer disposed on the organic light-emissive layer, wherein the cathode electrode layer includes: a first electrode layer disposed on the organic light-emissive layer; a second electrode layer disposed on the first electrode layer; and a third electrode layer disposed on the second electrode layer, wherein the second electrode layer is a conductive organic material layer. The second electrode layer can absorb heat from laser to reduce damage to the third electrode layer. Thus, penetration of external defect-causing factors into the organic light-emissive layer through the third electrode layer can be reduced.
