    • 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.
    • 用于显示其中抑制串扰的立体图像的装置。 交替显示在液晶显示面板上的左眼图像和右眼图像通过交替切换的具有左眼和右眼快门的眼睛快门观察。 通过在扫描电极阵列上依次提供扫描电压并且与扫描电压同步地在数据电极阵列上提供图像数据电压来在面板上显示图像。 显示面板被分成上下部分,它们沿相反方向分开扫描。 在第一场中显示左眼图像,在第一场中扫描两部分中的所有扫描电极,并且在第一场后的第二场中类似地显示右眼图像。 在适当设置眼睛快门切换定时的同时,在第一和第二场之间提供一定的时间间隔。 因此,串扰图像仅在靠近显示面板的上边缘和下边缘的有限区域中显示。 可以以单一扫描方式扫描显示面板,并且可以以较低的亮度保持所显示的图像,以抑制串扰图像。
