Abstract: The present invention provides a pointing input device, which sequentially outputs pointing position data indicating a pointing input position and push detection data from a push by the same pen or finger used for a pointing input. The pointing input device includes a display panel for displaying any pointing input information and an optical touch panel. The optical touch panel detects the pointing input in an input operation area, through which a display area is visible, and outputs the pointing position data. Piezoelectric substrates are attached to a transparent protective plate protecting the top surface of the display panel. When an operator pushes the transparent protective plate disposed at the lower part of the optical touch panel while carrying out the pointing input, the piezoelectric substrates output electric signals by which the push is judged. Then, the push detection data is outputted with the pointing position data.

Abstract: A display apparatus and an assembly of a driving circuit for the display apparatus having a display device, a film carrier with a lead to transfer a signal for driving the display device, and a bus board to supply a signal to the lead. A dummy lead is provided along the outside of each of an input side outer lead and an output side outer lead of the film carrier. A predetermined voltage is applied to the dummy leads. The predetermined voltage value is set to a value so as not to stationarily cause a DC bias for the voltage of the outer lead on the outside.

Abstract: Systems for initiating the execution of a macro by simultaneously depressing multiple keys and for reducing the misclassification of keyboard input by distinguishing between rollovers in normal typing and the simultaneous depression of two keys. Only keystrokes that follow a pause are considered candidates for macro initiation. Keystrokes not separated by a pause are dispatched to the operating system for normal processing. If a user types in a normal fashion, no macro is recognized, and the user experiences no unexpected behavior. A user dictionary of macro definitions is used to determine whether the first keystroke is part of a macro input pair.

Abstract: A coordinate input device of touch-type capable of giving an electric signal to a transducer, even if said transducer is disposed on a back surface of a substrate. The device contains acoustic wave transducers (piezoelectric vibrators), each functioning for oscillating a bulk wave (a first wave) toward a top surface of a substrate; a planar wiring formed on a back surface of the substrate by, e.g., transfer printing with conductive paste, for supplying the piezoelectric vibrator with electric power; diffractive acoustic wave mode couplers, each functioning for converting said bulk wave into a surface acoustic wave (a second wave) and vice versa; and a detector to detect scatter in the surface acoustic wave on the top surface of the substrate. Employing the planar wiring allows the wiring to be disposed even on the back surface of the substrate and also it may resolve the problem of fragility associated with a cable wiring.

Abstract: A color video display apparatus comprises a pixel array with each pixel containing one or more LEDs for generating each of the selected colors and a diffractive optical element positioned in front of the array to form the transmitted light into a substantially elliptical pattern. Improved uniformity for the apparatus is achieved by measuring the intensity of each separate color generating LED in each pixel, recording each intensity and varying the current to each separate color LED or LEDs so that every LED or LEDs responsible for each color to provide a suitable color output. A feature of the apparatus is that a number of separate modules, each having a pixel array, can be combined to construct a video image board. These boards have applications in such areas as billboards along roadways and as signs in stadiums.

Abstract: An interlace-type PDP is driven by an improved driving method so as to achieve a greater operating margin, higher resolution, and higher brightness. The interlace-type PDP is driven using odd and even frames in such a manner that the cells are grouped into cell groups such that each cell group includes two or three cells which are adjacent in a direction crossing the electrode pairs, and the cells are driven in units of cell groups. The grouping of cells is performed differently for even and odd frames such that, in one type of frame, locations of two or three cells grouped into each group are shifted by one cell, in the direction crossing the electrode pairs, from the locations of cells grouped together in the other type of frame.

Abstract: A method and apparatus for providing force feedback to a user operating a human/computer interface device and interacting with a computer-generated simulation. In one aspect, a computer-implemented method simulates the interaction of simulated objects displayed to a user who controls one of the simulated objects manipulating a physical object of an interface device. The position of the simulated object, as provided within the simulation and as displayed, is mapped to the physical position of the user object. This mapping can be broken under conditions that are effective to provide force feedback to the user which imparts a physical sensation corresponding to the interaction of the simulated objects.

Abstract: A driving method is used for driving the voltage-driven circuit of an organic light emitting diode display device. Within a frame period, data voltage is set to a negative data voltage for a pre-defined interval within a frame period. When the scanning voltage is set to a high voltage level, the negative data voltage is applied to the gate terminal of a driving thin film transistor. The gate remains at the negative gate voltage for a maintenance period and the driving thin film transistor has a constant threshold voltage. Hence, this invention provides a mechanism for maintaining a constant luminance from the organic light emitting diode despite an extended use, thus effectively increasing the working life of the display device.
