Patent number: 9419065Abstract: An electronic device may be provided with an organic light-emitting diode display with minimized border regions. The border regions may be minimized by providing the display with bent edge portions having neutral plane adjustment features that facilitate bending of the bent edge portions while minimizing damage to the bent edge portions. The neutral plane adjustment features may include a modified backfilm layer of the display in which portions of the backfilm layer are removed in a bend region. A display device may include a substrate, a display panel on the substrate having display pixels, and peripheral circuitry proximate the display panel and configured to drive the display pixels. A portion of the periphery of the substrate may be bent substantially orthogonal to the display panel to reduce an apparent surface area of the display device. The bent portion may include an electrode for communication with the peripheral circuitry.Type: GrantFiled: July 1, 2013Date of Patent: August 16, 2016Assignee: Apple Inc.Inventors: Brett W.

Publication number: 20160143168Abstract: An electronic device having protruding features and a method for molding the protruding features to the electronic device are described. The protruding features may be formed by a molding tool that releases a material that flows through several apertures of a substrate. Also, the molding tool is positioned with respect to the substrate such that the material from the molding tool flows from an interior region of the substrate to an exterior region of the substrate via the several apertures. Accordingly, each aperture extends from an opening of the interior region and to an opening of the exterior region of the substrate. In some cases, the apertures may include a conical shape. For example, the opening in the interior region may include a diameter greater than a diameter of the opening in the exterior region. In this manner, the material, when cured, is mechanically secured to the substrate.Type: ApplicationFiled: July 31, 2015Publication date: May 19, 2016Inventors: Adam T.

Patent number: 9312517Abstract: An electronic device may be provided with a display. The display may have an active area with an array of display pixels and an inactive border region containing metal lines and other support circuitry.

Patent number: 9207484Abstract: The described embodiments relate generally to liquid crystal displays (LCDs) and more particularly to thermal management of heat produced by an illumination source in an LCD module. High temperatures generated by the illumination source can cause color shifts in the LCD due to changes in any included LEDs and liquid crystals. One solution is to house the LCD module in a metal chassis and thermally couple the LED light bar to the metal chassis. Furthermore, the LCD module can be kept at a uniform temperature by transferring heat from a region near the LED light bar to a relatively cooler region of the LCD module. These approaches can minimize any alterations or shifts in color resulting from heat from the LED light bar.Type: GrantFiled: September 26, 2012Date of Patent: December 8, 2015Assignee: Apple Inc.Inventors: Keith J. Hendren, Dinesh C. Mathew, Nicholas Alan Rundle, Brett W. Degner
