Patent number: 9990064Abstract: An electronic device includes a stack assembly. The stack assembly is provided with a stack of sub-assemblies such as a display for rendering content, front lighting layered on top of the display for illuminating the display, a capacitive touch sensor layered on top of the front lighting for detecting touch inputs, and a cover glass layered on top of the capacitive touch sensor. Each sub-assembly is adhered to another sub-assembly with a film optically clear adhesive before coupling sub-assemblies with each other, which forms a touch-sensitive front-lit display that is capable of accepting user input and rendering content in low ambient light conditions.Type: GrantFiled: March 24, 2015Date of Patent: June 5, 2018Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Robert L.

Patent number: 9657904Abstract: Technologies are described herein for photobleaching a display. A display may be photobleached by exposing the display to light emitted by an external lamp and/or may be photobleached using one or more display lights of the electronic device during a burn-in period. In some examples, the light emitted by the lamp is filtered to remove wavelengths below a certain wavelength. The light that is received by the display from the lamp may include wavelengths between about 310 nm and 700 nm. These wavelengths correspond to visible light and near-visible light. The display may be exposed to the light for some duration or until some dose of light is received by the display. In other configurations, a burn-in period is performed for about eighteen hours.Type: GrantFiled: February 23, 2015Date of Patent: May 23, 2017Assignee: Amazon Technologies, Inc.Inventors: Guneet Sethi, Nhi A. Duong, Tin Quang Pham, Heather Kulani Coursey, Weihsin Hou, Robert L. D. Zenner, Saket Patil

Patent number: 7170185Abstract: The present invention relates to a method for connecting an integrated circuit chip to a circuit substrate. The method includes the step of pre-applying adhesive directly to a bumped side of an integrated circuit chip. The method also includes the steps of removing portions of the adhesive from the tips of the solder bumps to expose a contact surface, and pressing the bumped side of the integrated circuit chip, which has previously been coated with adhesive, against the circuit substrate such that the bumps provide an electrical connection between the integrated circuit chip and the circuit substrate. The adhesive is removed from the tips of the solder bumps using a solvent assisted wiping action. The pre-applied adhesive on the chip forms a bond between the integrated circuit chip and the circuit substrate.Type: GrantFiled: October 17, 2000Date of Patent: January 30, 2007Assignee: 3M Innovative Properties CompanyInventors: Peter B. Hogerton, Kevin Yu Chen, Joel A. Gerber, Robert L. D. Zenner
