  • Patent number: 9460678
    Abstract: When a 2D display is performed, a controller causes a first selection signal to be in an active state during a given period, and causes a second selection signal to be in the active state during another given period after causing the first selection signal to be in a non-active state. When a 3D display is performed, the controller causes the first selection signal to be in the active state at a given timing point, cause the second selection signal to be in the active state during a period when the first selection signal is in the active state, and thereby cause an overlapping period to arise during a period which is part of a selection period for selecting signal lines corresponding to the first selection signal, and which is part of another selection period for selecting signal lines corresponding to the second selection signal.

  • Patent number: 9448666
    Abstract: Different lamination methods may be used to create a touch sensor with a darkened side of metalized film facing the user. One lamination method includes laminating a metalized film to an optically clear adhesive (OCA) layer such that an edge of the metalized film including the termination pads remain un-adhered to the OCA layer. Flex-tails may be bonded to the termination pads at a later time by bending up the un-adhered edge. Anisotropic Conductive Film (ACF) may be placed on the termination pads prior to laminating the metalized films. Flex-tails may be placed onto an OCA layer in a location where the termination pads on the metalized film will be located when laminated to the OCA layer. A strip of ACF may be placed on the flex-tail pads. The flex-tails may be bonded to the termination pads of the metalized film prior to the metalized film being laminated.

  • Patent number: 9417696
    Abstract: An electronic device includes a touch-sensitive display, and a plurality of piezoelectric patch transducers disposed beneath the display. A controller is configured to switch each of the transducers between a tactile feedback mode to provide tactile feedback via the touch-sensitive display, and an object detection mode to provide acoustic detection of a contactless position of an object relative to the device. The object is free of contact with the device at the contactless object position. Using the same transducers to provide tactile feedback and object detection provides these features without additional costs associated with adding further components. A microphone of the device can receive ultrasonic signals, emitted from the transducers and via associated acoustic ports, and the device can process the received signals to determine a contactless three-dimensional gesture that is performed, for example above the display.

  • Patent number: 9417713
    Abstract: An image-capturing device configured for an optical pointing apparatus includes a plurality of image-sensing units arranged adjacently. The plurality of image-sensing units are configured to sense images of a surface and generate sensing signals that are used for evaluating the velocity of the optical pointing apparatus. The image-capturing device is configured to use different image-sensing units arranged differently to sense the surface according to the velocity of the optical pointing apparatus. When the optical pointing apparatus moves at a first velocity, the image-capturing device uses the image-sensing units configured to occupy a smaller area to sense the surface. When the optical pointing apparatus moves at a second velocity, the image-capturing device uses the image-sensing units configured to occupy a larger area to sense the surface. The first velocity is lower than the second velocity.
