Abstract:
A display able to recharge a battery of a portable device in close proximity includes a transparent layer, a displaying layer, a transmitting module, and a back shroud. The displaying layer is attached to the transparent layer. The transmitting module includes a transmitting coil attached to the displaying layer and a shielding layer shielding the transmitting coil and attached to the displaying layer. The back shroud houses the transmitting module and the displaying layer, and is attached to the transparent layer. The transmitting coil is configured for outputting electromagnetic waves to a receiving coil of an electronic device, causing the receiving coil to charge the electronic device. The instant application further provides an electronic device adapted to the display.

     DETAILED DESCRIPTION 
       [0011]    It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure. 
         [0012]    Several definitions that apply throughout this disclosure will now be presented. 
         [0013]    The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that is modified, such that the feature of the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like. 
         [0014]      FIG. 1  illustrates a wireless charging system can include a display  200  and a receiving module  20  (see  FIG. 4 ) employed in an electronic device  300 .
