  • Patent number: 5229754
    Abstract: The prism reflector installed immediately above an indicator's display surface consists of a prism and a flange portion that is flush with one surface of the prism and which extends from the periphery of that surface. The surface of the prism and the flange portion form a reflecting surface. A reflector plate is arranged to face the reflecting surface of the prism reflector and has a concave surface, whose light axis is inclined with respect to the reflecting surface of the prism reflector toward the thicker side of the prism. Light from the indicator's display enters the prism, is refracted as it leaves the reflecting surface, and travels toward the reflector plate's concave surface, which reflects the incident light back toward the reflecting surface of the prism reflector, which then reflects it toward the driver's viewing point.

  • Patent number: 5227771
    Abstract: A window displayed on a user interface can be incrementally enlarged or reduced by selecting an appropriate sizing icon. There are provided an enlarge icon and a reduce icon in the window title bar. To resize the window, the user selects the appropriate icon with the cursor. The window will change its border size according to a predetermined incremental value. The data that is displayed inside of the newly sized window is determined and then displayed. By continuously selecting one of the sizing icons, the window will be continuously sized in an incremental manner until the user terminates the selection or until the maximum or minimum window limits are reached. As the window is resized, the cursor remains attached to the selected icon. During resizing of the window, one border corner is fixed in position on the interface while the opposite border corner is moved.

  • Patent number: 5225823
    Abstract: A field sequential liquid crystal display has a backlight that provides different color fields and a liquid crystal display panel that has a matrix of cells. Data lines are coupled to the cells and provide gray level data to the cells. Select lines are coupled to the cells and enable the cells. The cells include integrated memories coupled to the data lines, these integrated memories storing gray level data received via the data lines. The integration of the memories on the display panel allows all of the cells on the panel to be charged approximately simultaneously so that the time any one color is backlighting the entire display approaches an optimum fraction of a frame.

  • Patent number: 5200739
    Abstract: Character generator which provides the displayed characters, when displayed simultaneously with a video picture, with a shadow in a complimentary or programmable color so that the readability is optimum under all circumstances without any unnecessary blanking of the video picture. To this end the character generator (43) is adapted to alternately address both the pixel to be displayed and at least one adjacent pixel in a character memory (171). A blanking signal (FBL), which blanks the received video picture dependent on both the pixel to be displayed and the adjacent pixel, is generated in a blanking circuit (20). While the video picture is being blanked, the characters are displayed in a foreground color and the shadow is displayed in a background color. The invention is applicable in television receivers, camera recorders and the like, using a character generator for displaying locally generated operating information (On Screen Display) or information supplied by an external source (Teletext).

  • Patent number: 5184115
    Abstract: In an arrangement wherein an inquiry and a choice of respones thereto are displayed on a CRT screen, a selection is made by holding a touch-screen device against the area of the screen corresponding to the desired response. Such a touch-screen device is designed to have an inductive coil in its tip. When an electron beam which scans the CRT screen sweeps across the tip of the touch-screen device, an electrical signal is induced on the coil. The touch-position or the selection is determined based on a knowledge of the position of the electron beam on the screen at the time of the electrical signal induction.

  • Patent number: 5172105
    Abstract: A display apparatus disposes a ferroelectric liquid crystal between a group of scanning electrodes and a group of data electrodes constituting an electrode matrix, and provides a driver that applies a scanning signal to the scanning electrodes and applies data signals to the data electrodes in synchronism with the scanning signal. The driver is controlled as to divide the scanning electrodes into a plurality of blocks each comprising a plurality of scanning electrodes and select the scanning electrodes with skipping of at least one scanning electrode apart so that starting scanning electrodes in neighboring blocks from which the skipping-selection of scanning electrodes is started in each block of the scanning electrodes have mutually different positional ranks respectively in the neighboring blocks, whereby flickering caused by either scanning drive or by repetition of black and white signals is effectively suppressed while the observability of a motion picture is retained.

  • Patent number: 5166670
    Abstract: An improved column electrode driving circuit can drive a matrix type display apparatus without necessitating that digital signals be transmitted between partial column electrode driving circuits. Each of the partial column electrode driving circuits is allocated with a number. In each of the partial column electrode driving circuits, a shift register shifts a sample signal to sequentially output it from a plurality of outputs. At each time when a predetermined number of clock pulses have been counted, a count signal is produced. When the shift direction is set to the right direction, a signal indicating the allocated number is produced. When the shift direction is set to the left direction, a signal indicating a number, which is obtained by subtracting the allocated number from a specified number, is produced. When this number and the clock pulse count number satisfy a predetermined relationship, the sample signal is output.

  • Patent number: 5159321
    Abstract: A pen-type computer input device is used to move a cursor on the display of a computer system or enter data such as of figures, letters, numerals, or the like into a computer system. The pen-type computer input device includes a shank, a pen nib disposed on the tip end of the shank, and a sensor disposed in the shank, for detecting the directions in which and the distances by which the pen nib moves in two perpendicular directions in a plane, in response to movement of the pen nib, and for producing an output signal representative of the directions and distances. Since the sensor can detect the distance by which the pen nib moves without any mechanical motion transmitting mechanism incorporated in the pen nib, the pen-type computer input device may be small in size and can be handled with ease.
