Abstract: A novel organic light-emitting pixel structure provides improved contrast pixels suitable for use in high-contrast passive- and active-matrix displays. A dark, low-reflectance film is placed on a reflective or transparent substrate, which acts to absorb and/or trap ambient light impinging on the pixel and improving its contrast between on and off states. Optical scattering is reduced by fabricating a vertical wall around each pixel which effectively blocks out light emitted from adjacent pixels, and prevents the scattering of the pixel's own emitted light. Light is emitted through a transparent upper electrode, which allows the substrate to be non-transparent. An active-matrix display is thus built on a single silicon substrate, with the crystalline silicon transistors needed to drive the active-matrix fabricated alongside their respective pixels, and with the walls surrounding the pixels formed from the drive circuitry itself.

Abstract: Gate lines and drain lines are arranged to cross each other on an inner surface of a substrate and display pixels are formed at individual intersections of these lines. For actuation of these elements, a drain driver, a gate driver, and a precharge driver are formed on the periphery of the substrate. Aluminum lines extend to respective circuits along the edge of the substrate from connecting terminals formed on the edge of the substrate. A sealing material is applied along the periphery of the substrate and an injection hole for liquid crystal is formed on one edge of the substrate. The drain driver is disposed on the edge opposite to the edge on which the injection hole is formed at a location as far from the injection hole as possible. Thus, the drain driver is distanced from the liquid crystal injection hole to prevent the failure of the display apparatus due to the fluctuation of a threshold value.

Abstract: White opaque fixed films in a fixed section are arranged in a two-dimensional matrix. On each fixed film, a cyan transparent film, a magenta transparent film, and a yellow transparent film that constitute a pixel are placed. By electrostatic force, these transparent films are driven and placed under the fixed film of an adjacent pixel, thereby controlling the color of the pixel. To generate electrostatic force, the fixed film and transparent film are provided with electrodes and an insulating film is inserted between these two films. The consecutive reversing of the polarity of both electrodes enables the transparent film to move in parallel with the fixed section. To achieve half tone display and no power consumption in displaying a still picture, an electrostatic mechanical latch mechanism that stops the film still in motion is employed.

Abstract: Image signals are converted from one color format to another using a lookup table based on interleaved indices generated from the components in the first color format. In a preferred embodiment, image signals in a YUV format are converted to image signals in a CLUT format by interleaving bits from the U and V components and appending bits from the Y component. By interleaving the U and V components, cache efficiency is improved when color conversion is implemented on a general-purpose processor with limited on-chip cache.

Abstract: A 3-dimensional image is obtained from a 2-dimensional display by varying the apparent distance of the image from the viewer on a pixel by pixel basis. This is done by positioning an array of pixel-level optical elements in alignment with the pixels in the image. In a preferred format, each of the optical elements is generally elongate and has a focal length which varies along its length with the result that the point along its length at which light enters the optical element determines the apparent visual distance of the associated pixel from the viewer. In the case of a cathode-ray tube application, controlling the position of entry of the light is done by controlling the electron beam to move a minute distance vertically as it scans horizontally. In a television application, the vertical distance may be determined by a depth component incorporated in the broadcast signal received by a television set.

Abstract: A new and improved ferroelectric liquid crystal display system having a matrix structure of pixel elements each including a transistor active switching device and a ferroelectric cell. Each switching device is coupled to an individual storage capacitor which is charged during each row select time when the switching device is activated, and which is discharged during each frame time when the switching device is deactivated. A plurality of multi-level or analog column drivers supply selected drive currents to charge individually the storage capacitors of a row of pixel elements to desired initial voltage levels corresponding to desired gray scale levels for the pixel elements during a row select time to maintain the liquid crystal pixel images for lengths of time proportional to the initial charge levels of the capacitors, which discharge until their individual voltages reach a threshold voltage within predetermined discharge times during one frame time.

Abstract: Conflicting requests for cursor control of displaying are resolved by priority. The cursors can reflect attributes of their control or those of their control units, with visual attributes being color, shape or the like. Priority may be established between each cursor and a range of areas acceptable for cursor movement subdivided from the screen, or according to a priority of allowable functions, or according to a priority of conflicting operating times, or a combination of the same. Simultaneous control of a plurality of cursors can be permitted when there is no conflict.

Abstract: An instrument ("INSTR") hardkey facilitates a change in settings of any instrument displayed in any of the windows that appears on a display. The user merely depresses the "INSTR" key and selects the instrument whose settings are to be changed by a softkey menu that is displayed when the "INSTR" hardkey is depressed. A color editor is preferably resident in the display and provides a superimposed window and softkey menu for enabling the user to adjust colors. An "Adjust Color" softkey allows the user to adjust one or all of six factors: red, green, blue, hue (tint), saturation (color or color level), and luminosity (brightness). The window preferably displays red, green, and blue bars in a bar graph format, which change in height as the user changes the red, green, and/or blue settings by a rotary pulse generator or a numeric keyboard. The window also shows readouts for hue, saturation, and luminosity which change as the user adjusts the values with the rotary pulse generator or the numeric keyboard.

Abstract: A computer system hating a digitizing tablet overlaying the display screen. The tablet serves as a user's primary input device. Various features of the system make it possible for the user to run and interact with standard programs designed for keystroke and mouse input and not designed for use with a tablet. In addition to the main processor, on which the user's programs are executed, there is an interface processor. In addition to a standard display buffer, there is an ink plane buffer for interface display data that is combined with the data from the standard display buffer on a pixel-by-pixel basis according to data from a mask plane buffer. The interface processor manages input from the tablet, presents feedback to the user by means of the ink and mask planes, and provides keystroke and mouse data to the main processor as if from a standard keyboard controller. The interface processor presents the user with a collection of simulated devices, including standard devices such as a keyboard and a mouse.

The media control module receives a composed image signal from the media bus and provides the composed image signal to a display device.

Abstract: The display combines an ordinary monochrome electronic visual display with a two-primary field-sequential display (FSD). This hybrid system provides full color, high spatial resolution, and high luminance. The FSD provides two of the three color primaries (i.e., red, green, and blue) using temporally separate color fields which alternate at twice the frame rate (e.g., 120 Hz). Its image is superimposed with the monochrome display's, which refreshes at a conventional frame rate (e.g., 60 Hz) and provides the third primary, thus yielding a full-color image. In this way, a full-color FSD is obtained without requiring the presentation of color fields at triple the frame rate (e.g., 180 Hz) or diminishing the FSD's luminous efficiency or color range. The system's maximum obtainable luminance is increased still further because the monochrome display's image does not timeshare with the other two primaries.
