Patent number: 10614752Abstract: An electronic device may be provided with an ambient light sensor. The ambient light sensor may be a color ambient light sensor or a monochrome ambient light sensor. The electronic device may have a light-emitting component such as a display. During operation of the display, the display emits light. To reduce noise due to the emitted light while measuring ambient light, the ambient light sensor may have optical structures such as wave plates and polarizers. Theses optical structures may overlap light detectors. The optical structures may be configured to prevent ambient light from reaching a first of the light detectors while allowing ambient light to reach a second of the light detectors. The ambient light sensor may be configured to receive ambient light that has passed thorough an inactive area of a display or that has passed through a pixel array in an active area of a display.Type: GrantFiled: September 27, 2018Date of Patent: April 7, 2020Assignee: Apple Inc.Inventors: Christopher M. Dodson, Aleksandr N. Polyakov, Guocheng Shao, Meng-Huan Ho, Niva A. Ran, Serhan O. Isikman, Volodymyr Borshch

Patent number: 9400412Abstract: An optical modulator includes a liquid crystal cell containing liquid crystal material having liquid crystal molecules oriented along a quiescent director direction in the unbiased state, and a voltage source configured to apply an electric field to the liquid crystal material wherein the direction of the applied electric field does not cause the quiescent director direction to change. An optical source is arranged to transmit light through or reflect light off the liquid crystal cell with the light passing through the liquid crystal material at an angle effective to undergo phase retardation in response to the voltage source applying the electric field. The liquid crystal material may have negative dielectric anisotropy, and the voltage source configured to apply an electric field to the liquid crystal material whose electric field vector is transverse to the quiescent director direction.Type: GrantFiled: July 16, 2014Date of Patent: July 26, 2016Assignee: KENT STATE UNIVERSITYInventors: Volodymyr Borshch, Sergij V. Shiyanovskii, Oleg D. Lavrentovich

Patent number: 9376619Abstract: A surface polymer-assisted vertically aligned (SPA-VA) liquid crystal (LC) cell has a surface alignment layer of surface localized polymer nano spikes capable of controlling the pretilt angle of liquid crystal molecules and ensuring fast switching characteristics. The deposition of the polymer nanospikes as a part of the alignment layer is achieved by polymerizing a small amount of a reactive monomer in vertically aligned liquid crystal with or without an applied voltage. Due to the alignment of liquid crystal molecules by the surface alignment layers, the polymerized polymer acts as an internal surface to modify and control the field-induced reorientation of the liquid crystal molecules. The SPA-VA LC cell realizes a stable alignment and the considerable advantage of the formation of polymer spikes via UV irradiation on both substrates of the cell. Furthermore, the switch-off of a SPA-VA is fast due to the enhanced surface anchoring strength by the surface-localized polymer nano spikes.Type: GrantFiled: February 15, 2011Date of Patent: June 28, 2016Assignee: KENT STATE UNIVERSITYInventors: Liang-Chy Chien, Volodymyr Borshch, Jeoung-Yeon Hwang
