Patent number: 10551706Abstract: The present invention is intended to control the color temperature of white exhibited by a liquid crystal display device. White is produced when light waves emitted through pixels associated with three colors of red, green, and blue have maximum intensities. The amounts of light emitted through the respective pixels are controlled by differentiating the shapes of the pixel electrodes disposed at the respective pixels from one another. Thus, the color temperature of white is controlled. Otherwise, the shapes of interceptive films disposed at the respective pixels are differentiated from one another in order to control light waves emitted through the respective pixels. Thus, the color temperature of white is controlled. The interceptive film may be shaped like the pixel electrode. Otherwise, the interceptive film may be realized with an interceptive pattern other than that of the pixel electrode or one of openings bored in a black matrix.Type: GrantFiled: March 1, 2019Date of Patent: February 4, 2020Assignees: Japan DIsplay Inc., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Ikuko Mori, Munenori Motooka, Ryutaro Oke, Kazunori Ojima, Kikuo Ono

Patent number: 10520787Abstract: A camera system includes an image sensor assembly and a tunable optical element. The tunable optical element is a gradient index (GRIN) lens created from a polymer dispersed liquid crystal and a coupled control element. The GRIN lens is tunable by applying an electric field to the optical element via a control element. The control element applies a voltage differential to the optical element inducing an electric field which changes the polarization of the PDLC within the optical element. The electrodes of the control element can include sheet resistors with a radially dependent voltage drop. The refractive index of the GRIN lens is dependent on the polarization of the liquid crystals within the optical element. Applying the electric field to the tunable element changes the optical properties of the grating.Type: GrantFiled: May 23, 2017Date of Patent: December 31, 2019Assignee: GoPro, Inc.Inventor: Scott Patrick Campbell
