Wireless charging through a display
An example mobile computing device includes a display; a battery; a wireless charging coil positioned to wirelessly transmit or receive electrical energy through the display; and circuitry configured to charge the battery using electrical energy received via the wireless charging coil.
1 . A folding mobile computing device comprising:
a first assembly having an inner and an outer surface;
a second assembly having an inner and an outer surface, wherein, when the folding device is fully opened, the inner surface of the first assembly is substantially coplanar with the inner surface of the second assembly;
an outer display positioned on the outer surface of the first assembly;
a continuous display positioned on the inner surface of the first assembly and the inner surface of the second assembly;
a battery positioned in the second assembly;
a wireless charging coil positioned to wirelessly transmit or receive electrical energy through the outer display;
a metallic shielding layer affixed to a back surface of the outer display, the metallic shielding layer including a cutout section overlying the wireless charging coil, wherein the wireless charging coil is positioned within the mobile computing device such that there is a gap between the wireless charging coil and the back surface of the outer display; and
circuitry configured to:
charge the battery using electrical energy received via the wireless charging coil; and
disable a touch sensor and one or more pixels of the display based on an activation state of the wireless charging coil.
2 . The folding mobile computing device of claim 1 , wherein the gap between the wireless charging coil and the outer display is at least 100 microns.
3 . The folding mobile computing device of claim 1 , wherein the second assembly includes a camera with an aperture positioned at the inner surface of the second assembly.
4 . The folding mobile computing device of claim 3 , wherein the folding device is configured to operate in a tabletop mode in which the folding device is partially opened with the outer surface of the first assembly is face down.
5 . The folding mobile computing device of claim 1 , wherein the wireless charging coil is a first wireless charging coil, the folding device further comprising:
a second wireless charging coil positioned within the second assembly and configured to wirelessly transmit or receive electrical energy through the outer surface of the second assembly.
6 . The folding mobile computing device of claim 1 , wherein the second assembly does not include a display at the outer surface of the second assembly.
7 . The folding mobile computing device of claim 1 , wherein the circuitry is further configured to:
adjust a graphical user interface displayed at the outer display based on an activation state of the wireless charging coil.
