摘要： A solid state dot sequential color display device is disclosed. A color image is formed in a liquid crystal display panel by breaking each picture element up into its three primary color components and presenting them in an adjacent manner. The space occupied by a trio of primary color elements is smaller than the resolving power of the human eye. Techniques of large scale integration (LSI) are employed to effect the required addressing circuitry as applied to a matrix array of triads of reflective electrodes in the dynamic scattering liquid crystal display panel. Arrangements used to form the basic color cells involved are: (a) deposition of band-pass filters in front of the display and (b) deposition of band reflection mirror in back of the liquid crystal material.

摘要： A system and technique for directing intensity modulated electromagnetic energy. The inventive system (10) includes an intensity modulated source of electromagnetic energy (12). Individual elements (22) in an array of energy directing elements (15) are activated in sync with the modulation of the energy source (12). In a particular implementation, the source (12) is a laser. The intensity of the laser is reduced during each successive field per frame. The energy directing elements (15), in this case, light directing elements, are implemented with an array of digital micromirrors. The light source (12) is modulated in intensity in accordance with a fixed modulation scheme. The mirrors (22) are selectively activated relative to the light source modulation scheme. Hence, the invention provides a gray scale output while allowing the time between mirror flips to be constant. This allows the system clocks to run synchronously and greatly simplifies the writing of data into the display as the time available for writing each bit is constant.

摘要： A flat panel liquid crystal display system formed by sandwiching a thin layer of liquid crystal material between a front electrode structure, split into rows or columns, and a back electrode structure formed into desired patterns and including addressing circuitry is described. Single polarity operation of a liquid crystal display system in which the direction of current flow in the liquid crystal material is reversed at the frame rate is a feature of the invention. Operation is accomplished so as to permit gray scale rendition as response to an applied video signal. Addressing circuitry demonstrating the applicability of large scale integration (LSI) techniques is also an important element of the invention.

摘要： A low bandwidth high brightness display system that utilizes a multiple beam cathode ray tube to write multiple rasters by concurrently scanning a plurality of lines with a selected number of beams. Each of the rasters covers a different portion of the screen so that the vertical deflection of the beam is reduced for each beam by a factor related to the number of beams. The system reduces the maximum data rate in writing speed relative to conventional arrangements with a resultant bandwidth reduction proportional to the number of beams. The concept is applicable to television viewing screens and field sequential color television to produce simultaneously a high resolution, high brightness and high quality display.FIELD OF THE INVENTIONThis invention generally relates to display systems and particularly to a high bandwidth television display system that operates with individual channels having a relatively small information bandwidth and with a high brightness by utilizing a multi-beam cathode ray tube to form a plurality of adjacent rasters in a first dimension that concurrently define the total display.DESCRIPTION OF THE PRIOR ARTTelevision type displays have been unable to develop a high resolution, high brightness and high quality display by using conventional scanning methods of either a single beam or even by using a multi-beam cathode ray tube.Multi-beam cathode ray tubes (CRT) are well known in the art and have been used for the generation of both color and black and white television displays. Examples of such multi-beam television displays may be found in the following U.S. Pat. Nos. 3,448,316; 3,596,126; 3,546,516; and 3,594,600, all assigned to a common assignee. For example, in 3,448,316 a lens system is used for eliminating optical errors such as spherical aberration and/or coma from the television display. The optical correction is accomplished by the use of a plurality of electron beams which are made to converge substantially at the optical center of a lens-like electrostatic focusing means which is common to all of the beams and focuses beams on to an electron receiving screen. This particular device generates a color diaplay of the sequential color dot type.Another example of display systems utilizing a multi-beam cathode ray tube may be found in Serial Number 327,896, now U.S. Pat. No. 3,821,796, "Improved Television Display System" which is assigned to the same assignee as this present application. That application discloses a multi-beam cathode ray tube used in conjunction with a field sequential color television system to produce a color display. The electron beams are in line and create a raster by sweeping the plurality of beams across the face of the display in a paintbrush-like fashion. The plurality of electron beams is then used to sweep another series of lines immediately below the previous trace. A transparent rotating color wheel, having the three primary colors -- red, green, and blue, is disposed in front of the display for creating the sense of color in the viewer's eye.The problem with most multi-beam cathode ray tubes is that they must generally be long in length from the viewing screen to the electron gun. The greater length for multi-beam cathode ray tubes is necessitated by the fact that the individual beams must be focused in close proximity to each other and the cathodes must be separated from each other because of the space that each individual cathode requires. Another drawback of most multi-beam CRTs is that generally a high bandwidth is required along with a high deflection rate in the Y-axis. If brightness is to be maintained at a high level a high bandwidth generally results in a poor resolution since brightness is dependent upon a high current beam and higher current results in beam spreading, therefore low resolution. A high current beam further requires higher power, more complex circuitry at greater cost and also reduced reliability.SUMMARY OF THE INVENTIONAccordingly, it is the object of the present invention to provide a high resolution, high brightness and high quality raster display.It is another object of the present invention to provide a raster display utilizing a plurality of electron beams having a low bandwidth.It is another object of the present invention to provide a raster display by a cathode ray tube being shorter in length than heretofore possible.It is yet another object of the present invention to provide a multi-beam CRT with a small beam deflection in the Y dimension.It is still another object of the present invention to provide a plurality of electron beams for simultaneously generating a plurality of rasters on a display.In accordance with the foregoing objects a raster display generation system utilizing a multiple beam CRT includes a display surface, a source for generating a plurality of electron beams and control means. A first electron beam traces a first raster encompassing a first vertical position in a first dimension on the display screen. A second electron beam traces a second raster immediately adjacent to the first raster in a first dimension. A third electron beam traces a third raster immediately adjacent to the second raster in the same dimension. A fourth electron beam traces a fourth raster immediately adjacent to the third raster. The plurality of rasters is created simultaneously by the plurality of electron beams. An individual line of a raster is generated by moving a beam across the face of the screen; the beam is then deflected downward in a second dimension to trace the next line in that raster. Each beam is controled to define an individual raster and the plurality of rasters are generated at the same time, on a line by line basis, by the individual beams.

摘要： There is disclosed a liquid crystal image projector which is suitable for use as an image source in an aircraft head-up display system. In this application, the projector provides extremely bright and high contrast symbology for the aircraft pilot. More generally, the projector has application wherever a television-type raster and/or calligraphic symbology display is needed. The increase in brightness and contrast ratio is achieved by using a reflector to concentrate light from a light source onto the liquid crystal display cell from whence it is reflected through an optical aperture stop in the reflector to the projecting lens and thence to a viewing surface.

摘要： A liquid crystal field sequential color display is formed by presenting three monochromatic images corresponding to the three primary colors, that is, red, green and blue, consecutively in a repetitive sequence and at a rate greater than the flicker fusion frequency for human vision. Each field contains a monochromatic image showing how the intensity of the primary color to which it corresponds varies over the entire image area. The black and white imaging techniques typically used for forming the intensity pattern for each field are transformed into the required sequential monochromatic image patterns through the use of colored filters in one embodiment or colored light in another embodiment. The novel result is obtained by the combining of flat panel liquid crystal display technology with color display technology. This invention disclosure shows a practical method for combining these techniques into a device that will form a full color image.
