Abstract:
1. A liquid crystal display, comprising: a liquid crystal display panel having quad cells each including a R sub pixel, a G sub pixel, a B sub pixel, and an ECB sub pixel; a storage means that stores first to n-th look-up tables each holding a mapping of one of first to n-th mappings of ECB brightness data to cell location information for the quad cells of the liquid crystal display panel; an image processor that calculates a brightness data distribution of an image to be displayed using the liquid crystal display panel using input RGB data for one frame period; a viewing angle controller that selects one of the first to the n-th look-up tables, the selected look-up table depending on the calculated brightness data distribution; and a data aligner that combines ECB brightness data received from a look-up table selected by the viewing angle controller with the input RGB data, and then aligns the combined RGB data and ECB brightness data for display in accordance with a quad cell structure.
