Abstract

See full text

An LCD device is provided, which makes it possible to simultaneously display two images on a screen at unequal resolutions. This device is comprised of an LCD panel having pixels arranged in a matrix array and first and second display areas, where part of the pixels are located in the first display area and the remainder are located in the second display area. First and second horizontal drivers supply first and second data to the pixels arranged along the odd-numbered rows of the matrix in the first and second display areas, respectively. Third and fourth horizontal drivers supply third and fourth data to the pixels arranged along the even-numbered rows of the matrix in the first and second display areas, respectively. A first vertical driver selects the pixels arranged along the odd-numbered rows in the first and second display areas. A second vertical driver selects the pixels arranged along the even-numbered rows in the first and second display areas. The first and third horizontal drivers simultaneously supply the first and third data to the pixels arranged along one of the odd-numbered rows of the matrix in the first display area and those arranged along an adjoining one of the even-numbered rows of the matrix to the supplied row in the first display area, respectively.
