Abstract: A printing system is provided having interactive sample page preview and selection capabilities. An operator or user of a printing system, such as a xerographic copier, laser printer, or multi-function device, may visually confirm the print quality of pages printed by the system by requesting that a sample page, i.e., an extra copy of a page being printed within a print job, be printed and delivered to an alternate output tray for inspection. The present disclosure provides the ability to print the sample and show what was printed as a preview on the screen. The present disclosure additionally provides a preview of the sample page prior to its printing and delivery to an alternate tray. Based upon the previewed image, an operator may choose to print a sample page corresponding to that image, or choose another page. Additionally or alternatively, sample pages may be printed based on temporal criteria and system parameters.

Abstract: A front surface of the opposite electrode of a liquid crystal display panel is formed in a curved shape. The relation between the reflecting surface of the pixel electrode and the curved surface of the opposite substrate is defined so that a leaving direction of the light that is reflected by the first face of the opposite substrate is different from a leaving direction of light that is emitted from the first face of the opposite substrate after having been reflected by the pixel electrodes through the liquid crystal layer. Thus, undesired light on the front surface of the opposite substrate is separated from light that is displayed. Consequently, an image free of dazzling and deterioration of contrast ratio due to undesired reflected light can be obtained with a high contrast ratio. In a display apparatus containing the reflection type liquid crystal display, an incident surface to a dichroic prism is an inclined surface including a curved surface, not a surface that is perpendicular to the optical axis.
