    Abstract: A video interface linking a base station with a remote display, e.g., a head-mounted display, converts input video signals from NTSC or PAL formats into modulated video signals containing repetitive sequences of frame times with embedded audio and control signals. Each frame time includes equal consecutive color field times. Frame rates are converted by inserting selected repeating color frames into the datastream. Bursts of image information occupy a portion of each field time. During each data burst, the display is loaded with pixel luminance data. Between bursts, the display is illuminated by a color LED. Two video displays can be driven alternately, i.e., the first display loads while the second is illuminated. The modulated video signal can travel through the atmosphere on an infrared (IR) beam with a wavelength between 700 nm and 1100 nm. In one embodiment, the beam is scattered from a diffuse reflecting surface. Alternatively, the beam is shaped by a shaping lens.

  • Patent number: 6014258
    Abstract: In a color image display apparatus, assuming that time response characteristics of light emission by red, green and blue light emitting cells have values TR, TG and TB, the difference between the values TR and TG is less than that between the values TR and TB and that between the values TG and TB. The apparatus has a subfield arrangement including a portion where a light emitting weight gradually decreases and a portion where the light emitting weight gradually increases, or a subfield arrangement to obtain a plurality of light emission peaks in one field.

  • Patent number: 6008929
    Abstract: An image displaying apparatus and method is provided which can provide a satisfactory display with a gradation of intensity even with a spatial light modulator which provides a binary light modulation. A light from a light source 1 is modulated by a spatial light modulator 3 which modulates a light at each pixel thereof correspondingly to a pixel data of an image to be displayed. When the pixel state of the spatial light modulator 3 is being changed, the light source 1 is turned off. When the pixel state of the spatial light modulator 3 is steady, a light pulse is irradiated from the light source 1 to the spatial light modulator 3 to display the image.

  • Patent number: 5901483
    Abstract: A display element includes a disk which rotates through 160.degree.-180.degree. to display a bright or a dark side in a viewing direction in ON and OFF positions respectively A constantly on LED is arranged to illuminate the disk in ON position for viewing in a first arc including the viewing direction. The disk masks the LED to viewers in the OFF position of the disk. In addition to light from the illuminated disks, the components may be arranged so that viewers over a second arc may view the LED directly when the disk is in ON position. The elements may be arranged in arrays to form a changeable sign. Thus the array may be made up of single elements, of columns of such elements or of a combination of elements and columns.

  • Patent number: 5828355
    Abstract: A general purpose Liquid Crystal Display controller apparatus for controlling an LCD driver is operable to control an LCD having a plurality of individually addressable pixels arranged in lines. The apparatus has a pixel group generator for generating a pixel group for addressing respective groups of pixels on the lines of the LCD and a display buffer for storing image codes representing a desired image to be displayed on the LCD, the image codes being accessed in response to respective pixel groups. An identifier is provided for identifying each of the image codes as being a direct pixel group control code or a character addressing code and a character table is provided for storing character sub-line codes for controlling pixels in an addressed group, the character sub-line codes being accessed in response to the character addressing codes.

  • Patent number: 5825341
    Abstract: A control interface for a liquid crystal display having more than 80 characters uses a pair of controller/driver devices each having inputs for eight data bits but being adaptable to operate with four data bits from a 4-bit microprocessor. A standard 8-bit microprocessor is used to control the controller/driver devices by connecting the four bits of a low data nibble of the microprocessor to the four high data bits of one controller/driver and four bits of a high data nibble of the microprocessor to the four high data bits of the other controller/driver. The control interface can interface to liquid crystal displays with less than 80 characters without microprocessor modification.

  • Patent number: 5729243
    Abstract: A matrix display of light reflecting elements is capable of displaying images represented by data codes received from a variety of different sources at different respective frame rates. The codes are stored at whatever frame rate they are received, but are read at a subframe rate which is an integral multiple of each of the different frame rates.

  • Patent number: 5612710
    Abstract: A large scale video display of the present invention is designed to receive a standard NTSC video signal and display it on a large scale array of low cost, voltage or current controlled lamp transducers. The video signals are received by a video capture device which receives and digitizes the video signal. A host processor formats the digital data into a number of 16 bit data words each corresponding to a pixel. A coprocessor receives the 16 bit data words and reformats the data. The reformatted data is connected to a large scale display by a fiber optic connection. The display includes a number of transceivers which receive the formatted video data in a memory buffer. The transceivers also receive a board map from the coprocessor. The map indicates which light boards correspond to each part of the memory where the frame image is stored. This information is used by a number of controllers to determine which lights to turn on and at what level of brightness for any given time.

  • Patent number: 5412398
    Abstract: A tetrode type electrophoretic display includes local anode lines electrically grouped into groups having the width of a character. In operation, the local anode may be used to blink selected characters by applying appropriate voltages to the various electrodes of the display in the proper sequence. Sequencing is controlled by a computer and associated software.
