Abstract
An image display system has a main-driver, a sub-driver, a display panel, and a timing generator. The main-driver supplies plural types of video signals having different standards of resolution, while the sub-driver, independent from the main-driver, supplies a black signal whose brightness can be controlled. The display panel includes a vertical scanning circuit for sequentially selecting rows of pixels, a horizontal scanning circuit for distributing the video signals to columns of the pixels so as to be written into the selected pixels, and an auxiliary scanning circuit for distributing the black signal to columns of the pixels so as to be written into the selected pixels. The timing generator controls the respective scanning circuits in the display panel by distributing control signals in accordance with the resolution of the video signals. Thereby, the video signals are written into a display region in a screen including the pixels which has the numbers of rows and columns adapted for the resolution, and the black signal is written into the pixels belonging to a blank region outside the display region.
