Transparent Substrate Having Light Entrapment Capability (i.e., Waveguides) Patents (Class 345/176)
  • Patent number: 8648819
    Abstract: A capacitive two-dimensional (2D) touch panel has three sets of interleaved electrodes. A first set of electrodes is spaced apart along the y-direction and these are galvanically connected to each other by a resistive strip connected at either end to a connection line. A second set of electrodes is also arrayed along the y-direction and these are galvanically connected to each other via a notionally non-resistive first connection. A third set of electrodes is also arrayed along the y-direction and these are galvanically connected to each other via a notionally non-resistive second connection. The second and third sets of electrodes are interleaved without galvanic cross-conduction to provide a gradient along the x-direction to resolve touch position in the x-direction. The first set of electrodes resolves touch position along the y-direction. Passive or active capacitive sensing techniques may be used to acquire the position information from the 2D touch panel.

    Abstract: An apparatus operable in touch-input mode and scanning mode uses a light guide and a camera to look through a slanted facet at one corner of the light guide. The light guide has an upper surface for placing a touch object or an item for scanning. An angular sensitive grating is located on lower surface having fringes such that when a light beam directed from a location P on upper surface toward lower surface at a predefined direction, it is diffracted by the grating and guided toward the slanted facet. The diffracted beam exits the slanted facet at an exiting angle indicative of the location P. When an object or item is placed on upper surface, it causes changes in exit beam intensity. From exiting angles and intensity changes, a camera is able to locate touch objects or to acquire an image of the scanned item.

    Abstract: Present day, technology allows flexible screens to be produced, particularly the OLED screen technology. The invention relates to a device equipped with a flexible screen emitting light. Part of the light rays emitted by the optical cells is imprisoned between the substrate layers and reflecting from one layer to the other exit at the side of the screen. Photoelectric detectors are arranged on the side of the screen in order to capture the incident light. Depending on the position of the cells emitting the light and the values supplied by the detectors, the central processing unit determines the areas of flexion applied to the screen. Hence, it is possible to introduce commands by exerting flexions on certain areas of the screen. The invention also relates to a device having a flexible screen and flexion sensors capable of executing the method for the introduction of commands.

    Abstract: A method of removing portions of a conductive layer comprising a transparent conductive material and/or a metallic material disposed on a plastic substrate used for capacitive touchscreen devices includes providing a plastic substrate having a conductive layer disposed on a surface thereof and removing portions of the conductive layer at the surface of the plastic substrate to establish a pattern of electrically isolated conductive portions on the surface of the plastic substrate. The conductive portions or traces are electrically connected to a touchscreen controller, which is operable to determine a location of a touch or proximity of an object at or near the surface of the plastic substrate responsive to a detected change in capacitance. The removal process may comprise etching or laser ablating portions of the conductive layer at the surface of the plastic substrate.

  • Patent number: 8487914
    Abstract: An optical finger navigation device. Embodiments of the optical finger navigation device include a light guide film (LGF) including a finger interface surface, a light source in optical communication with the LGF to provide light from the light source to the finger interface surface, a sensor, and a navigation engine. At least a portion of the LGF exhibits total internal reflection (TIR). The sensor detects light from the LGF in response to contact between a finger and the finger interface surface which modifies reflection of light out of the LGF to the sensor. The light detected by the sensor is changed over at least a portion of the sensor in response to the contact between the finger and the finger interface surface. The navigation engine is configured to generate lateral movement information indicative of lateral movement of the finger relative to the sensor, in response to the detected light.

  • Patent number: 8456320
    Abstract: In one embodiment, a method for providing feedback for a page turn requested on a device is provided. The device may be an electronic book (e-book) device or another device that is configured to display electronic documents. A movement on the display of the device is detected. The method determines that a page turn of the document is being requested based on the movement on the display. The method determines a light-based feedback to indicate that a page turn is being processed. The computing time to process a page turn and display a new page may be slow as perceived by the user. Accordingly, the light-based feedback is used to indicate to the user that the page turn has been received. A plurality of light sources are used to provide the light-based feedback based on a location of the movement. For example, as a user swipes a finger across a display, light sources that follow the motion of the finger are illuminated to simulate a page turn.
