  • Patent number: 5825347
    Abstract: A system for depicting a complete image from a plurality of partial images is provided. A set of one or more physical objects are positioned on at least one side of a display device. Each of the physical objects represents a different discrete portion of a complete image, each discrete portion creating a continuous visual image with a remaining portion of the image. The display device displays the remaining portion of the image as a visual representation on a display screen. At least a portion of the visual representation portrays a visual extension of one or more of the physical objects. The visual representation on the display screen, the visual extensions, and the set of one or more physical objects together define the complete image. A method implemented by the system for providing the complete image is also provided.

  • Patent number: 5821913
    Abstract: A method and apparatus is provided for displaying an enlarged image on a liquid crystal display apparatus capable of displaying colors, and in particular, a liquid crystal display method and apparatus that can enlarge an image at an arbitrary ratio and display the outline of the enlarged image smoothly. On a display panel of a color liquid crystal display apparatus in which display dots each comprising an array of three subpixels displaying red (R), green (G), and blue (B) are arranged in a matrix, three pieces of raw-direction original display brightness data to be displayed in three subpixels are extended and subjected to predetermined weights of brightness to form enlarged display brightness data. This data is sequentially output to the subpixels to extend the original image in the raw direction of the display panel before display.

  • Patent number: 5818400
    Abstract: A display device that includes a display medium having a planar display area over which an image is generated, a first and second optical point beam each directed in the display medium coplanar with the planar display area, and beam controllers that scan each of the optical point beams to selectively interfere in the display area within a region defined by the intersection of the optical point beams to produce an intensity in the region that has enhanced visibility relative to the individual optical beams propagating in the display medium outside of the region. The beam controller may be an elongated reflector having a reflecting surface upon which a linear array of liquid crystal modulators are controlled to selectively transmit segments of a linear beam incident on the linear array, in order to provide the optical beam by selectively reflecting segments of the linear optical beam into the display medium.

  • Patent number: 5815157
    Abstract: An addressing scheme for efficient memory use for storing textures with borders. Memory space is allocated for the texture maps, borders, and submaps equaled to two times the width times the height of the texture map to be stored. The memory space is then divided into a rectangular map space having a left-hand portion and a right-hand portion. Storage is accomplished by storing the main texture map on the left-hand portion of the map space. Submaps are then aligned along the bottom edge of the map space at the right in the right-hand portion. Finally, the borders are stored beginning at the top of the right-side portion of the rectangular space. The four corner edges of the borders are stored below the texel borders in the right-side portion.

  • Patent number: 5815129
    Abstract: A liquid crystal display including a driving circuit is provided. The LCD in which one gate line is driven by both left and right gate drivers includes a couple of switching means which are placed between the gate driver and gate line, the couple of switching means being activated and deactivated by switching control signals to switch the output of the gate driver. When one of the gate drivers does not operate, the output of the gate driver having the operational problem is prevented from being applied to the gate lines, by a switching operation. Therefore, even when only one of gate drivers operates, the display panel can function properly, thereby preventing the lowering of picture quality and improving product yield.

  • Patent number: 5812133
    Abstract: An industrial controller executing a graphical language employs a comparator circuit for monitoring the address locations of memory used to store the control program and its data. A cursor positioned on a graphics representation of the program is used to identify a particular graphical element to be monitored and the address of the starting instruction for that element is loaded into the comparator. An interrupt generated by the comparator causes the generation of a histogram listing the particular rungs name and the times at which it has been executed, useful for verifying and monitoring the operation of a control program. A snapshot of data values used by the element of the program at the time of its execution may also be stored to verify the condition under which the element executes.
