Patent number: 10185200Abstract: A thin border display for an electronic device may comprise an optical assembly that includes a support frame and an electrophoretic display (EPD) structure attached to the support frame in a manner that allows for the display of the electronic device to exhibit a “thin border” or “borderless” look at a periphery of the electronic device. A portion of the EPD structure may at least partly curve around a curved portion of the support frame, the curved portion of the support frame being near the periphery of the support frame. In some embodiments, the EPD structure includes a transparent protective substrate disposed on a rear surface of a flexible backplane substrate within the flat outer region where a driver chip is disposed on a front surface of the flexible backplane substrate. The transparent protective substrate protects the driver chip attachment from being damaged during manufacture.Type: GrantFiled: June 23, 2016Date of Patent: January 22, 2019Assignee: Amazon Technologies, Inc.Inventors: Robert Arthur Sprague, Angeles Marcia Almanza-Workman, Wilfrido Loor Canizares, Siddharth Gupta, Vikram Srinivas

Patent number: 9836152Abstract: The single layer compressive substrate force sensor may include electrode patterns formed directly on a first side and second side of the compressive substrate. At least some of the electrode patterns are configured to provide a change in capacitance proportional with a compressive force applied to at least one of the electrode patterns, which compresses the compressive substrate. The single layer compressive substrate force sensor may include a first top electrode and a second top electrode pattern separated by an insulator to void contact between the electrode patterns. In operation, the first top electrode pattern and the second top electrode pattern are configured to provide projective capacitance, and thus provide detection of light touches or hover actions by an object.Type: GrantFiled: June 25, 2015Date of Patent: December 5, 2017Assignee: Amazon Technologies, Inc.Inventors: Jung Sik Yang, Charles Robert Watson, Edward Albert Liljegren, Angeles Marcia Almanza-Workman, Reuben Eric Martinez

Patent number: 9682886Abstract: A side surface of a cover glass of an electronic device may be coated with a curable ink to reduce leakage of light from the side surface. The ink may be deposited on the side surface via a pen comprising a reservoir, a valve, and a nib. The nib may comprise a fiber bundle through which pigment particles may pass. The ink may be precisely deposited via the nib on the side surface without visible ink overflowing to a front surface or a back surface of the cover glass.Type: GrantFiled: June 17, 2014Date of Patent: June 20, 2017Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Angeles Marcia Almanza-Workman, Shan Cheng, Gregory Turner Witmer, Yean Chan Woon, Keith Ho Soo Suan

Patent number: 9465472Abstract: A touch-sensitive display for an electronic device may include a touch sensor comprising a low birefringence substrate, ultraviolet (UV) stabilizers, and a metal mesh disposed on at least a portion of the low birefringence substrate. The low birefringence characteristic of the touch sensor substrate causes the touch sensor to exhibit low haze, high transmittance, and substantially no color, which provides improved optical properties over conventional touch sensor substrate materials used with metal mesh film. In some embodiments, the retardation value of the touch sensor substrate may be no greater than about 15 nanometers (nm). Additionally, the UV stabilizers prevent the substrate from yellowing and becoming brittle from exposure to UV radiation.Type: GrantFiled: December 9, 2014Date of Patent: October 11, 2016Assignee: Amazon Technologies, Inc.Inventors: Angeles Marcia Almanza-Workman, Heang Heng, Thiagarajan Marimuthu, Lakshman Rathnam, Krishan Yadav, Jianjun Yang
