摘要： A light shutter is provided wherein a first plate which includes a pixel electrode for use in applying a includes a background electrode located adjacent the pixel voltage potential across a ferroelectric material also electrode and substantially surrounding the pixel electrode, whereby an electronic mask can be created adjacent the pixel electrode in the ferroelectric material. A second plate which, along with the first plate sandwiches the ferroelectric material, includes a backplane electrode which is used in conjunction with the pixel and background electrodes on the first plate for applying voltage potentials across the ferroelectric material. By maintaining a minimal amount of spacing between the background electrode and the pixel electrode, a voltage potential can be applied between the background and backplane electrodes so that the ferroelectric material located adjacent the pixel electrode can be maintained in, for example, a non-light transmissive state whereby the contrast between the pixel and inter-pixel regions is greatly improved. Image bars or displays can be formed by arranging a plurality of light shutters (and consequently, pixel electrodes) on the first plate with one or more background electrodes surrounding the plurality of pixel electrodes. Additionally, the background electrode and/or other electrodes can be used for applying electric fields to the ferroelectric material which are non-parallel to the polarization direction of the molecules of the ferroelectic material to reduce the time required to change the ferroelectric material between light transmissive and light blocking states.
摘要翻译：提供了一种光闸，其中包括用于施加的像素电极的第一板包括邻近铁电材料电极并且基本上围绕像素电极的像素电压电位附近的背景电极，由此可以相邻地形成电子掩模铁电材料中的像素电极。与第一板夹着铁电材料一起的第二板包括背板电极，其与第一板上的像素和背景电极结合使用，以跨越铁电体材料施加电压电位。通过在背景电极和像素电极之间保持最小量的间隔，可以在背景电极和背板电极之间施加电压电位，使得位于像素电极附近的铁电材料可以保持在例如非光透射状态，从而大大提高像素和像素间区域之间的对比度。可以通过在多个像素电极周围设置一个或多个背景电极而在第一板上布置多个光快门（以及因此的像素电极）来形成图像条或显示器。此外，背景电极和/或其他电极可以用于向铁电材料施加电场，铁电材料不与铁电材料的分子的偏振方向平行，以减少在透光性之间改变铁电材料所需的时间和阻光状态。

摘要： A linear array of liquid crystal shutters mounted near a photoreceptor surface and arranged transversely to the direction of travel of the photoreceptor surface, an array of multiplexed thin film transistors (TFT's) connected to the array of liquid crystal shutters for electrically driving the shutters and logic means connected to the multiplexed array of thin film resistors selectively pulsing the liquid crystal shutters to selectively expose the photoreceptor surface a line at a time. The system further includes a single backplane and circuit means for producing an electric field between the backplane and electrodes of each of the liquid crystal shutters to prevent passage of light through the shutters and means for selectively de-energizing each of the pairs of electrodes for predetermined time period in response to the receipt of input data signals.

摘要： A display for use in conjunction with a copier. The disclosed display comprises two microprocessors for controllably displaying information on a display panel of a xerographic copier. A first microprocessor is primarily responsible for energizing alphanumeric elements to either send messages to the copier user or to prompt the user to interact with the copier. A second display is a liquid crystal display wherein selectively energizable liquid crystal elements corresponding to copier components can be rendered visible under the control of the second microprocessor. An overlay pattern can be placed above the liquid crystal display to present to the user in outline form the copier architecture with which he is interacting. This overlay can be changed as the copier configuration is changed. The electronics for controlling the display of alphanumeric allows the utilization of different fonts and/or different languages. This flexibility allows the copier to prompt, and/or display information regarding copier status in various languages without a redesign of the display unit.
