Communication device and display incorporating antennas between display pixels

摘要

A display, such as for a touch-sensitive communication device, can include a transparent cover glass, pixels that emit light through the cover glass, and multiple antennas positioned along respective paths in an inactive area between the pixels. The antennas do not obstruct the light produced by the pixels, and can therefore be composed of opaque materials, such as metallic thin films, without affecting the optical properties of the display. In some examples, several antennas can have the same size and shape but different orientations, so that a radio can switch between or among the antennas to optimize reception. In some examples, the antennas can have different sizes and/or shapes, so that the antennas can send and/or receive radio signals in different frequency ranges of the electromagnetic spectrum. In some examples, locating the antennas in the display can allow the device to include a metallic housing.

主权项

1. A display, comprising:
a transparent cover glass; a plurality of pixels configured to controllably emit light through the cover glass, the plurality of pixels arranged across an area of the cover glass, the plurality of pixels defining an inactive area between at least a portion of the plurality of pixels and within the area of the cover glass where the plurality of pixels are arranged; a first antenna composed of a conductive material and positioned in a first path in the inactive area, between the at least a portion of the plurality of pixels; and a second antenna composed of a conductive material and positioned in a second path in the inactive area, between the at least a portion of the plurality of pixels, the second path being different from the first path; wherein the cover glass is part of a layered structure, the layered structure including layers that have touch sensitivity and that control a light output of the plurality of pixels; wherein the first antenna is disposed between a first pair of adjacent layers in the layered structure; and wherein the second antenna is disposed between a second pair of adjacent layers in the layered structure, different from the first pair.
