  • Patent number: 9483150
    Abstract: A touch sensor mechanism for a touch display device, includes a cover lens made by a transparent material having a dielectric constant greater than 4.5 and a compression strength greater than 700 MPa for generating a finger's touching capacitance (CF) while a user's finger of a user touch thereon; and a sensor device module including a plurality of sensor devices having a sensor parasitic capacitance (CP). The cover lens and the sensor device module are disposed in the touch display device in such a manner that a ratio of a standard deviation value (?U) of the finger's touching capacitance (CF) of the cover lens to the sensor parasitic capacitance (CP) of the sensor device module is a signal-to-noise ratio (SNR). The SNR is adjusted along with the finger's touching capacitance (CF) by reducing the thickness of the cover lens.

  • Patent number: 9272390
    Abstract: A pad conditioning tool includes a sapphire substrate with a specific orientation plane, wherein the specific orientation plane is selected from a group consisting of a-plane, c-plane, r-plane, m-plane, n-plane and v-plane, the sapphire substrate further defining a mounting surface; and a plurality of sapphire dressing particles and a plurality of scrapers formed on the mounting surface of the substrate in a predetermined geometric arrangement, wherein the dressing particles are scattered between an adjacent pair of the scrapers. In case a wafer polishing pad is conditioned by the dressing particles of the pad conditioning tool, the scrapers are capable of removing abrasive waste and particles from the wafer polishing pad during a dressing operation, thereby forming new trenches and cilia structure on a polishing surface of the wafer polishing pad.

  • Patent number: 9075201
    Abstract: A polarization conversion mechanism for a touch screen display includes a crystal layer and a polarizing layer. The crystal layer includes a birefringent crystal for changing phase delay effect in accordance with the orientation of the crystal axis thereof. The polarizing layer includes at least one linear polarizer such that an incident light after hitting a display module of the display device reflects and emits out through the linear polarizer and the crystal layer sequentially as reflection light in form of circularly polarized light or elliptically polarized light. The assembly of the crystal layer and the layer are installed to the display device and/or touch screen display in such a manner that the assembly is located on the display module thereof.
