摘要:
A device for displaying a stereoscopic image in which cross-talk is suppressed. A left eye image and a right eye image alternately displayed on a liquid crystal display panel are viewed through an eye shutter having a left eye and a right eye shutter which are alternately switched. The image is displayed on the panel by sequentially supplying scanning voltages on a scanning electrode array and supplying image data voltages on a data electrode array in synchronism with the scanning voltages. The display panel is divided into an upper part and a lower part which are scanned separately in opposite directions. The left eye image is displayed in the first field during which all scanning electrodes in both parts are scanned, and the right eye image is similarly displayed in the second field following the first field. A certain time interval is provided between the first and second fields, while properly setting the eye shutter switching timing. Thus, cross-talk images are displayed only in limited regions close to upper and lower edges of the display panel. The display panel may be scanned in a single scanning method, and the displayed image may be held with a lower brightness to suppress the cross-talk images.
