Abstract:
1. A liquid crystal display (LCD) apparatus comprising: an LCD panel including a first substrate, a second substrate and a liquid crystal layer that is between the first substrate and the second substrate; and a driving section providing the LCD panel with a plurality of first image signals based on original RGB gray-scale data during a plurality of first field intervals having the same time interval within a frame, and providing a second image signal to enhance a luminance based on the original RGB gray-scale data during a second field interval that is longer than each of the first field intervals within the frame, wherein the second image signal has a level substantially equal to a maximum level of the original RGB gray-scale data, and the first image signal has two color gray-scale data in which a gray-scale data corresponding to a minimum level is excluded, wherein one of the two color gray-scale data has a level and a width which define a size substantially equal to a size defined by a level exceeding the minimum level and a width of a corresponding gray-scale data, and another of the two color gray-scale data has a level and a width which define a size substantially equal to a size defined by a level exceeding the minimum level and a width of a corresponding gray-scale data, wherein the second image signal has a width greater than respective widths of the two color gray-scale data, and the maximum level of the original RGB gray-scale data with respect to the second image signal remains the same, wherein the levels of the two color gray-scale data are increased in proportion to the decrease of the widths, wherein the first image signals include a red data, a green data and a blue data, and the second image signal includes a white data, and wherein the applying time of each of the red, green and blue data is less than or equal to about ¼ frame, and the applying time of the white data is greater than about ¼ frame.
