摘要： This is a portable electro-magnetic book (or reusable book frame) device to display digital format files requiring minimal energy. Nothing of this kind is currently available to the public. A user will be able to have single a book like device with almost unlimited source of digital files to display on the device. The effect is achieved by application of electro-magnetic field (electro-magnets) onto permanent magnets, whose ends are black and white accordingly, which form out of themselves viewable symbols (such as letters, punctuation, words, drawings etc.) creating an image of a book page.The realization of this device will make disposable paper books obsolete.

摘要： The invention provides a display matrix system using display elements of the electromagnetic type. The system differs from others in that the currents applied to the display elements are unidirectional as there are no electrical switching components per element. This reduces the drive circuitry needed for the matrix. Selection of the display elements relies on current pulses of variable width.In accordance with an aspect of the invention each one of a row or column of coils are connected together by N conductors, such that it is only necessary to drive 1/N of the coils in a row or column at a time:In accordance with a further aspect of the invention means are provided which enable variation in the electrical pulse width applied to a display element in response to variation of one of ambient temperature and supply voltage.
摘要翻译：本发明提供一种使用电磁型显示元件的显示矩阵系统。该系统与其他系统不同之处在于，施加到显示元件的电流是单向的，因为每个元件没有电气开关元件。这减少了矩阵所需的驱动电路。显示元件的选择依赖于可变宽度的电流脉冲。根据本发明的一个方面，线圈的一行或一列中的每一个由N个导体连接在一起，使得仅需要一次驱动1 / N个线圈的行或列：根据提供本发明的另一方面的装置，其能够响应于环境温度和电源电压之一的变化而允许施加到显示元件的电脉冲宽度的变化。

摘要： Large scale information display panels made up of basic picture elements running to hundreds, even up several thousand color elements, are useful for being viewed for advertising, transportation information, traffic control, news, weather, finanical data and other information normally generated by computers. The system has capability in alphanumeric and also for color graphics designs in four colors with use of a basic display element with two intersecting planes rotational about an axis at the intersection of the two planes. A three plane element provides for designs in six colors. The basic two plane display has each face of each of the two plane surfaces coated or impregnated with a different color and a single permanent bar magnet is enclosed in one of the plane forms perpendicular to the axis of rotation. The bar magnet acts as an armature for rotation of the element with current flow through a coil and a holding force with magnetic circuit material resist shifting from a set orientation in a two coil driven configuration. This is with "L" shaped ferrous metal strips providing support for the rotatable display elements and holding a vertical coil and horizontal coil in place for each rotatable display element. Addition of a third coil positioned in element to element dividers for each element and inclusion of a third perpendicular color plane along with two permanent bar magnets at right angles to each other in each element extends the concept to a six color display.

摘要： A digitally addressed magnetically actuated ambient light display panel is disclosed which incorporates a thin flexible magnetic membrane suspended between a ferromagnetic member and a transparent window in a fluid of a contrasting color. A plurality of small electromagnetic elements are disposed along the face of the ferromagnetic member adjacent to the magnetic membrane, which are capable of selectively magnetizing the ferromagnetic member at discrete locations. The magnetized ferromagnetic member attracts or repels the magnetic membrane in accordance with the magnetic polarity induced in the ferromagnetic member by the electromagnetic elements. Repelling the membrane against the face of the window at predetermined locations displaces the fluid between the membrane and the window and permits the contrasting color of the flexible membrane to become visible. A selectively repelled membrane generates characters or patterns visible under ambient light conditions.

摘要： A movable element is selectively operated to press an opaque member into engagement with a selected region of a light diffusing boundary to convert such region between a light absorbing condition and a light reflecting condition. An array of movable elements can be selectively actuated to define a variety of patterns that can be presented on the illuminated side of the boundary. The movable elements may be piezoelectric or magnetostrictive elements. In one embodiment, the movable elements carry a soft black rubber surface for contact with an optical boundary defined by the rear face of a transparent glass panel. In another embodiment, the movable elements carry smooth black surfaces for contact with rubber films on the rear face of a transparent glass panel to define an optical boundary.

摘要： This disclosure provides systems, methods and apparatus for addressing an array of pixels in a display. In one aspect, an electromechanical device includes a movable element coupled between a first and second actuator, and a charge distribution circuit arranged to electronically couple the first actuator to the second actuator and capable of equalizing a potential between the first actuator and the second actuator. In certain implementation, a method for addressing an array of pixels in a display, where a given pixel in the array of pixels includes a light modulator coupled between first and second actuator capacitors, includes equalizing a potential between the first actuator capacitor and the second actuator capacitor prior to discharging and re-charging the actuator capacitors. Equalizing a potential may include transferring charge from one actuator capacitor to another actuator capacitor until the voltage across each actuator capacitor is approximately equal.

摘要： Reflective color displays. Each pixel or sub-pixel of the display preferably comprises at least one magneto-optical element that can rotate in more than two stable positions, displaying a color corresponding to each position. Thus each element can display more than one color (in addition to black, if desired). Multiple elements may be combined to form a sub-pixel and/or pixel. The displays are preferably highly light reflective and preferably have low power consumption and increased resolution.
