Abstract: A method for driving a plasma display panel in which any one of a scanning electrode and a sustaining electrode is shared by neighboring display cells interposed therebetween. At least one condition selected from the group consisting of a voltage of a sustaining pulse, a pulse width of a sustaining pulse, and a pulse applying interval of a sustaining pulse is changed in relation to a polarity of the sustaining pulse. The sustaining pulse is applied to the scanning electrode and sustaining electrode by a predetermined number with relation to an image data during a sustaining period.

Abstract: A light emitting device that achieves long life, and which is capable of performing high duty drive, by suppressing initial light emitting element deterioration is provided. Reverse bias application to an EL element (109) is performed one row at a time by forming a reverse bias electric power source line (112) and a reverse bias TFT (108). Reverse bias application can therefore be performed in synchronous with operations for write-in of an image signal, light emission, erasure, and the like. Reverse bias application therefore becomes possible while maintaining a duty equivalent to that of a conventional driving method.

Abstract: Bending wave vibrations propagating in a substrate of a touch input device are sensed. Provision is made for discriminating between sensed vibrations propagating in the substrate indicative of an intended touch and sensed vibrations propagating in the substrate indicative of an unintended touch. In response to the sensed vibrations propagating in the substrate indicative of the intended touch, a wake-up signal is generated. The wake-up signal is communicated to a control system of the touch input device for transitioning the control system from a sleep state to an operational state.

Abstract: The present invention provides a technology that enables projection images to be overlaid with embellishment effects without depending on the capabilities of the image supply apparatus. A projection display apparatus that projects images onto a screen responsive to given image data, comprises: an embellishment effect memory for storing embellishment effect data representing an embellishment effect image that can be used to embellish an arbitrary image; an image embellishment section that generates embellished image data by overlaying an original image represented by the given image data and the embellishment effect image; a light modulation unit that is driven responsive to the embellished image data pixel by pixel; and an optical system for projecting onto the screen the embellished image obtained by the light modulation unit. A projection display apparatus superimposes the embellishment effect on the projected image without having to rely on the capabilities of an image supply apparatus.

Abstract: A manually moveable FPS control unit for moving a cursor on a console display screen, which unit has a forward end housing an optical sensor adapted for selective positioning in front of an axis of rotation at a rearward location. Rotation about the rearward axis creates arc movements of the optical sensor, and these arc paths are translated into horizontal cursor movements on a display screen. A manually controlled pistol-shaped-grip provides rotation of the unit about the rear vertically-located axis. Roller wheel and other conventional control switches are mounted on the grip handle itself for natural and quick control over images displayed on the screen.

Abstract: The invention relates to a coordinate detecting method for a touch panel. Firstly, a plurality of X-axis and Y-axis I/O ports are converted to a plurality of X-axis and Y-axis scanning wires respectively by orthogonal method. Polling signals are transmitted to X-axis I/O ports, and are transmitted to the X-axis scanning wires. According to the polling signals, a plurality of X-axis detection signals are stored. A largest X-axis detection signal and a second largest X-axis detection signal are determined by compared method so as to calculate a X coordinate position of the sensor pen touching the touch panel. The steps are repeated to calculate the Y coordinate position of the sensor pen touching on the touch panel. According to the coordinate detecting method of the invention, the number of the I/O ports can be reduced, and the resolution of the touch panel can be improved.

Abstract: The invention reduces power consumption when, for example, a mobile personal computer is in a power-saving mode or when a cellular phone is in a wait mode, in an electro-optical apparatus, such as a liquid crystal display of the subfield drive type used as a display apparatus for various apparatuses. Three different settings “64”, “16” and “2” are enabled as the number of gray scale levels in an electro-optical apparatus, the number of subfields becoming smaller as the number of gray scale levels is reduced. When a large number of gray scale levels is not required (when in the power-saving mode, the wait mode, etc.), a low number of gray scale levels is set, so that the own capacitance of a liquid crystal layer and storage capacitance are charged and discharged less often.

Abstract: Force effects for a graphical user interface of a computer are provided based on user preference information, which indicates the types of graphical objects in the graphical user interface which are to have force effects associated with them, and at least one particular force effect assigned to each of those types of graphical objects. An output of a force sensation by a haptic feedback device to the user is based on those assigned force effects and occurs when a displayed cursor controlled by a user interacts with a graphical object having one of the types. An architecture for a host computer allowing multi-tasking application programs to interface with a feedback device is also disclosed.

Abstract: A force-feedback input device includes an operating unit to be operated by an operator, a position detector for detecting an operating state of the operating unit, a torque generator for applying a force to the operating unit, a controller for controlling the driving of the torque generator so that a force in accordance with the operating state is applied to the operating unit, an ambient thermometer for detecting the ambient temperature of the torque generator, a storage unit, and a power supply. The controller calculates a new estimated temperature of the torque generator based on higher one of the ambient temperature, and an estimated temperature immediately before the power stoppage, which is read from the storage unit, and reduces the current supplied to the torque generator to cool the torque generator when the new estimated temperature exceeds a predetermined value.

Abstract: A three-times magnified pattern of a central target pixel and horizontally contiguously adjacent sub-pixel patterns next thereto are determined on the basis of a reference pattern that has a rectangular profile and further that consist of eight-neighboring pixel about the target pixel. The determined three-times magnified pattern is allocated to three sub-pixels that form the target pixel. The determined sub-pixel patterns are allocated to horizontally adjacent sub-pixels next to the target pixel. As a result, a black area defined by the target pixel is displaced rightward by an amount of a sub-pixel without any change in black area size that corresponds to three sub-pixels. This feature inhibits a variation in output image density, which otherwise would conspicuously occurs as a result of a varied object line width.

An intermediate current that is k times the data current Idata generated in the second driving transistor included in the current-conversion circuit segment is supplied to the first current-supply transistor in the final current-conversion circuit segment.

Abstract: Pixel data and black image data are simultaneously and respectively written to two pixels positioned in different pixel rows and this operation is performed two times on each of the different pixel rows to write corresponding data to all pixels in each of the different pixel rows. When the above operation is performed on all pixel rows within one frame period, a data latch circuit may hold only half the number of data that have to be held in the data latch circuit of the conventional signal line driving circuit, resulting in reduction in the size of data latch circuit chip and reduction in space occupied by a display device.
