  • Patent number: 7242395
    Abstract: An input device and a driving device able to be made thin and secure sufficiently large vibration amplitude are provided. The input device comprises an input panel, a current conducting element for conducting a driving current, and a magnetic field application unit for applying a magnetic field on the current conducting element. Both of the current conducting element and the magnetic field application unit are arranged in the peripheral region of the input panel. The magnetic field applied by the magnetic field application unit is parallel to the input panel and intersects the current conducting element. When the input panel is touched, a driving current is fed into the current conducting element, and a force is imposed on the current conducting element and the magnetic field application unit, making them move. This movement further drives the input panel to vibrate. Consequently, input operations can be recognized by feeling the vibration of the input panel.

  • Patent number: 7158103
    Abstract: The invention enhances, at low cost, the display performance of an electro-optical device to reflect the light emitted from a light-emitting layer to an electrode opposite to a substrate. Within a circuit part, a silicon layer and a condenser electrode formed from a first metal layer thereon, with a gate-insulating layer sandwiched therebetween, is provided under a pixel display part. Further, a second metal layer forms a power source line parallel to a signal line with a width covering the pixel display part and with a thickness having reflexibility. The light emitted and transmitted through an anode from an organic EL layer, is reflected upwardly by the power source line and is emitted from the pixel display part. A storage capacitor is formed in a layer below the power source line by the silicon layer, the condenser electrode, and the power source line. As a result, the space of the circuit part is efficiently used.

  • Patent number: 7123214
    Abstract: It is intended to solve the problem that, when an operator performs an operation using two-dimensional input means while seeing a picture frame seen from a viewpoint of the operator, an input operation is difficult to perform when the direction of the line of sight of the operator is unstable, since a designated direction greatly deviates in a world coordinate system. For that purpose, viewpoint information is detected, and an instruction of the operator for operating a position of a pointer image is input. A designated direction in a pointer coordinate system is obtained in accordance with the operator's instruction, and the pointer image is generated based on the designated direction. The pointer coordinate system is changed from the detected viewpoint information in accordance with a specific instruction of the operator.

  • Patent number: 7116301
    Abstract: When time division gradation display is carried out by setting a display state of an electro-optic element capable of R-gradation display A times in one frame period, the present invention determines the weights of the bit data to be such as 20:21:22:23?1: . . . , in which a conventional ratio regulation of 20:21:22:23: . . . i.e., 1:2:4:8: . . . is changed by at least one part at or later the third bit so as to satisfy the relation of B<RA where B expresses the number of display gradations. With this arrangement, it is possible to realize the time division gradation display with a desirable number of scanning lines and the desirable bit weight ratio, without significantly changing the actually-recognized image. On this account, the range of the electro-optic device, capable of setting each stage of outputs in the frame period to be a desirable value, can be enlarged with respect to a matrix display device using the time division gradation display.
