Abstract
A display controller including a frequency discriminator for attaining modes of horizontal and vertical frequencies of video signals inputted thereto according to horizontal and vertical sync signals, a memory for setting therein a screen mode matching the input video signals according to the determined frequency modes, and a horizontal timing signal generator and a vertical timing signal generator capable of arbitrarily setting horizontal and vertical display positions of the video signals. Obtaining the horizontal and vertical frequencies of the video signals, the controller conducts a control operation to generate horizontal and vertical timing signals associated with the horizontal and vertical frequencies. Even when the number of dots of the LCD panel is different from the number of dots supplied during a video display period from the input video signals, the resultant image can be presented in the central screen portion of the LCD panel.
