A multi display device includes a row drive circuit, a column drive circuit and a column line selection circuit. The row drive circuit drives first row lines of a first display panel and second row lines of at least one second display panel. The column drive circuit drives first column lines of the first display panel and second column lines of the second display panel. The column line selection circuit controls a connection between the column drive circuit and one of the first column lines and the second column lines based on a column line selection signal.

Multi display device and method of controlling the same

A partial region on a screen can be selected for highlighting. Information related to the partial region is transmitted from a computer to a computer monitor. In one embodiment, the partial region information is sent over a different port from the one used to send video data. The image processor adjusts contrast and sharpness of the partial region according to the partial region information. Adjustments are made for differences in a coordinate system between the computer site and the display device. The partial region can be selected from the computer or from a user interface on the computer monitor. Selected partial regions can be moved in conjunction with movements of windows containing the image. Highlighted selected regions can also be automatically disabled when the window is deactivated.

Method and apparatus for adjusting contrast and sharpness for regions in a display device

A method for adjusting the contrast of a background region in a display device is provided. A video signal for a background region is received in a background region mode. The gain of the video signal is adjusted responsive to a background region control signal thereby adjusting the contrast of the background region. The result is a high quality display device.
