  • Publication number: 20200309509
    Abstract: A method for assessing the profile of a tool using a non-contact tool setting apparatus that includes a transmitter for emitting a light beam and a receiver for receiving the beam. The receiver generates a beam intensity signal describing the intensity of received light. The setting apparatus is mounted to a coordinate positioning apparatus that allows the tool to be moved relative to the setting apparatus. The method includes using the coordinate positioning apparatus to move the tool relative to the setting apparatus along a tool inspection path, the tool inspection path being selected so that the light beam is traced substantially along a periphery of the tool to be inspected. Beam intensity data is collected describing the beam intensity signal that is generated by the receiver as the tool inspection path is traversed and analysis of the collected beam intensity data is used to assess the tool profile.

  • Publication number: 20190064591
    Abstract: Embodiments of a display device are described. A display device includes a backlight unit having a light source and a liquid crystal display (LCD) module. The LCD module includes a phosphor film and a filter element. The phosphor film is configured to receive a primary light, from the light source, having a first peak wavelength and to convert a portion of the primary light to emit a secondary light having a second peak wavelength. The second peak wavelength is different from the first peak wavelength. The filter element is optically coupled to the phosphor film and is configured to allow the secondary light to pass through the filter element and to block an unconverted portion of the primary light from passing through the filter element.
