Patent Issued for Flexible Display Devices

August 5, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventors Rothkopf, Fletcher R. (Los Altos, CA); Janis, Andrew J. M. (Toronto, CA); Dabov, Teodor (San Francisco, CA), filed on July 6, 2011, was published online on July 22, 2014.

The assignee for this patent, patent number 8787016, is Apple Inc. (Cupertino, CA).

Reporters obtained the following quote from the background information supplied by the inventors: "This relates generally to electronic devices, and, more particularly, to electronic devices with flexible displays.

"Electronic devices such as cellular telephones, media players, and computers are often provided with displays. For example, electronic devices may be provided with liquid crystal displays. Liquid crystal displays are often mounted under a rigid layer of cover glass. The cover glass protects the liquid crystal display from damage, but the rigid nature of the cover glass and other display layers render the display inflexible.

"Flexible display technologies are available that allow displays to be bent. For example, flexible displays may be formed using flexible organic light-emitting diode (OLED) display technology.

"It would be desirable to be able to use flexible display technology to provide improved electronic devices."

In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "Electronic devices may be provided that contain multiple housing portions. The housing portions may include, for example, first and second rectangular housing portions.

"The housing portions may be coupled together using hinges. The hinges may include hinges based on a three-bar linkage, hinges based on a four-bar linkage, hinges with slotted members, hinges formed from flexible support structures, and hinges based on flexible housing structures.

"Flexible displays may be mounted to the housing portions overlapping the hinges. When the housing portions in a device are rotated relative to each other, the flexible display may bend. Hinges may be configured to allow the flexible display to be placed in a front-to-front configuration in which the active side of the display faces itself or a back-to-back configuration in which the active portions of the display face away from each other. To avoid stretching the display, the display may be tensioned with tensioning structures and dispensed from a roller or an opening in a housing structure.

"Engagement structures may be used to help the housing grip external objects and to hold the housing portions in desired positions. The hinges may also be provided with rotational detents to help hold the flexible display in desired positions.

"Further features of the invention, its nature and various advantages will be more apparent from the accompanying drawings and the following detailed description of the preferred embodiments."
