Abstract:
Electronic devices may be provided that contain flexible displays and internal components. An internal component may be positioned under the flexible display. The internal component may be an output device such as a speaker that transmits sound through the flexible display or an actuator that deforms the display in a way that is sensed by a user. The internal component may also be a microphone or pressure sensor that receives sound or pressure information through the flexible display. Structural components may be used to permanently or temporarily deform the flexible display to provide tactile feedback to a user of the device. Electronic devices may be provided with concave displays or convex displays formed from one or more flexible layers including a flexible display layer. Portions of the flexible display may be used as speaker membranes for display-based speaker structures.
Abstract:
A system and methods to extending the overall display area for a device. At or near the borders of a device, pixel pitch between adjacent pixels may be increased such that overall pixel placement may be provided closer to a border of a display of a device. In one embodiment, pixel drive circuitry may be located in the spacing between adjacent pixels. Additionally, various optical systems and techniques may be utilized to provide an appearance of a lack of a border around the display such as decreasing the size of border pixels, overdriving the border pixels, or utilizing a light pipe on a surface above the border pixels.
Abstract:
An optical coating includes multiple layers of different materials and thicknesses and is disposed proximate a transparent display cover for an electronic device display. The optical coating transmits most visible light, reflects most non-visible light and substantially absorbs blackbody radiation generated from within the electronic device. The optical coating can be readily removable from the electronic device display either alone or in combination with a removable transparent display cover. The multiple layers comprise two or more materials having alternating low and high indices of refraction. The arrangement and thicknesses of the layers are designed based upon the thickness and optical properties of the transparent display cover. in another embodiment, an internal optical coating. The internal optical coating can also be specially formulated to replace a typical internal anti-reflective coating proximate the visual display unit.
