ABSTRACT:
The present invention provides a display driver circuit having a simple configuration due to a decrease in the number of voltage levels and capable of preventing deterioration of contrast ratio in display drive by using MLS, an electro-optical device, and a display drive method. First to fourth bits of grayscale data corresponding to a display pattern for three lines are supplied to each ROM. The ROMs decode and output 4MLS operation results for a display pattern defined by the first to fourth bits of the grayscale data and a dummy display-pattern corresponding to the display pattern based on orthogonal functions defined by combinations of a scan pattern and a dummy scan pattern of a virtual electrode based on a field signal.
