Abstract
A video display device including an integrated atypical/typical defect compensation circuit is disclosed. The video display device includes a display panel, a memory storing atypical/typical defect information used to compensate atypical/typical defect regions of the display panel, and an integrated atypical/typical compensation circuit including a first compensator for compensating input data to be displayed on the atypical/typical defect regions, using the atypical/typical defect information from the memory, and a second compensator for finely compensating the data compensated by the first compensator, using first and second dithering patterns. The compensation circuit supplies data to be displayed on normal regions, without compensation. The video display device also includes a timing controller including a dithering unit for finely compensating data output from the integrated atypical/typical compensation circuit, using a third dithering pattern different from the first and second dithering patterns, and a panel driver for driving the display panel under a control of the timing controller.
