美国“现实视觉”公司最近宣布,研制出了新型计算机三维液晶显示屏。该显示屏的外观与一般液晶显示屏没有区别,但却能在观看者不用佩带特殊眼镜的情况下,给人以逼真的三维感受。最新一期英国《新科学家》杂志报导说,新型三维液晶显示屏借助于使稍有区别的不同图像分别进入人的左、右眼,便能获得立体效果。不同的图像可通过隔行扫描的方式呈现于普通液晶显示屏上。其中,进入左眼的图像显示于偶数行,进入右眼的图像位于奇数行。为了获得立体效果,新型显示屏采用了新颖的后照光装置。该装置可采用普通
The United States “Real Vision” company recently announced that it has developed a new type of computer 3D liquid crystal display. The appearance of the display and the general LCD screen is no different, but it can be in the viewer without wearing special glasses, giving a realistic three-dimensional experience. The latest issue of the New Scientist magazine reports that the new three-dimensional liquid crystal display (LCD) achieves three-dimensional effects by allowing slightly different images to enter the left and right eyes of a person. Different images can be presented on a normal LCD by interlacing. The images entering the left eye are displayed in even rows and the images entering the right eye are located in odd rows. In order to obtain three-dimensional effect, the new display uses a novel backlight device. The device can be used normally
