摘要： A single liquid-crystal display can be used to be either of direct-vision or projection type, if required. Separate display devices for monitor and OHP are not required. Further, power consumption can be reduced, with the service life of the display being prolonged to improve economy.The liquid-crystal display includes a display housing which receives a liquid-crystal panel, a driver circuit unit and a cooling fan, the display housing being detachably mountable in a back light stand. When the display housing is mounted or dismounted in the back light stand, the fan and back light can automatically be turned on or off to reduce the power consumption. The liquid-crystal panel can be prevented from being degraded by cooling it by way of the fan.

摘要： In a display housing, first and Second liquid-crystal panels are disposed in parallel with each other, and a fluorescent lamp is positioned beside both ends of a gap between these panels. Thus, when used for a transmission type display, e.g. an OHP, the first liquid-crystal panel for light shutter is set in a transmission condition to transmit light from a light source for the OHP or the like and to irradiate the second liquid-crystal panel for displaying an image, thereby projecting the image in a magnified size onto a screen or the like. When used for a direct-vision type display, e.g. a monitor for a personal computer or the like, the first liquid-crystal panel is set in a shading condition to effect diffuse reflection of light from the fluorescent lamp by the first liquid-crystal panel and to irradiate the second liquid-crystal panel, thereby providing a direct-vision image.
摘要翻译：在显示器壳体中，第一和第二液晶面板彼此平行地设置，荧光灯位于这些面板之间的间隙的两端附近。因此，当用于传输类型显示时，例如， OHP，用于光快门的第一液晶面板被设置在透射条件下以从OHP等的光源透射光并照射第二液晶面板以显示图像，从而将图像投影到在屏幕上放大尺寸等。当用于直视式显示时，例如，用于个人计算机等的监视器，将第一液晶面板设置在阴影状态，以通过第一液晶面板进行来自荧光灯的光的漫反射，并且照射第二液晶面板，从而提供直观的图像。

摘要： An image information processor for a liquid crystal display by a digital driver is intended to provide image display near to a source image by making continuous-tone image display by pseudo representations. The image information processor generates L-bit image display data based on P-bit source image data, L being less than P. Added to source image data of a picture element of the Nth frame (where N is a natural number of 2 or greater) is error data corresponding to the picture element of the (N-1)th frame at the same position as the picture element of the Nth frame. The high-order L bits of the P-bit data resulting from the addition are used as image display data of the picture element of the Nth frame and at least one bit of the remaining low-order bit data is held as error data of the picture element of the Nth frame. Thus, error data of a picture element of one frame is added to the same picture element of the next frame, thereby lessening the brightness difference between both the picture elements and smoothing a time change in brightness.
