Patent ID: 7965267

Claim:
A liquid crystal display, comprising: a liquid crystal display panel having a liquid crystal cell at each intersection area of gate lines and data lines, which is driven by a frame divided into first and second fields and includes a display area having a specific area and a non-specific area; an interface part outputting a first data for applying the first data to the display area during the first field; a video processor outputting a second data for displaying in the specific area and a third data for displaying the non-specific area during the second field, the second data being generated from converting the first data to have different brightness level from the first data; a memory temporarily storing the second and third data; a position designator designating the specific area of the liquid crystal display panel where the second data is implemented; a timing controller realigning the first to third data; a data driver applying the first data to the display area during the first field, and applying the second data to the specific area and the third data to the non-specific area during the second field; and a gate driver supplying a scan pulse, wherein the second data has different brightness level from the third data, and the third data is a black data, wherein the liquid crystal display panel displays a video signal of the first data in the first field, and then display the second data at the specific area and the third data at the remaining area in the second field, wherein the brightness level of the second data is higher than brightness level of the first data, wherein the position designator designates the specific area in accordance with a program in a computer system, and wherein the liquid crystal display is driven at a high speed and, at the same time, in a high picture quality mode, the video signal is applied to the liquid crystal panel at the specific area and the non-specific area in the first field of one frame.
