    Abstract: Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function.

  • Patent number: 10120464
    Abstract: An optical touch system includes two touch devices, two optical sensing devices, and a processing module. When the optical touch system is in use according to an optical touch method, the two touch device are used to touch a touch surface and emit first light and second light with different wavelengths respectively. The two optical sensing devices are disposed at the circumference of the touch surface and individually receive the first light and the second light to generate an optical sensing signal. The processing module receives the two optical sensing signals and determines a touch position on the touch surface for each touch device according to the two optical sensing signals. Therefore, the touching by each touch device is independent, so the optical touch system and the optical touch method can allow touch operations for different purposes to be performed simultaneously.

  • Patent number: 9389769
    Abstract: Internet connected electrical switches can benefit from an electronic rather than mechanical means to indicate their output power level. In one embodiment a touch-controlled dimmer switch is disclosed, including an interactive, uniformly illuminated bar of light, indicating the output power state of a dimmer switch. In response to a user moving their finger on a touch-sensitive front cover the dimmer switch illuminates corresponding regions with well-defined edges on a touch sensitive cover. The illuminated regions can be elongated, wider than a typical finger and encompass the most recently touched location, thereby providing improved feedback between the finger position on a touch sensitive surface and the operating point of an electrical switch.

  • Patent number: 9244561
    Abstract: Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.

  • Patent number: 9229583
    Abstract: A system for determining a location of an object on a planar surface includes a time-of-flight sensor having sensing elements that provide a field of view for the time-of-flight sensor. The system also includes a mirror attached to the shaft of a motor for reflecting the field of view of the time-of-flight sensor across the planar surface. The system also includes electrical circuitry configured to receive range images from the time-of-flight sensor as the field of view is swept across the planar surface and process the range images to identify the object in at least one of the range images. The electrical circuitry is also configured to calculate a location of the object on the planar surface relative to the motor based on an angle of the shaft associated with the at least one range image and based on a distance of the object from time-of-flight sensor.
