Late last month a new LG patent application was published by the US Patent & Trademark Office revealing that 3D elements and cool LED lighting could be coming to future LG's smartphones. LG's patent FIGS. 9A and 9B noted in our cover graphic illustrate states of a stereoscopic cover portion mounted to a smartphone. As shown in FIG. 9A, the stereoscopic cover portion provides only a stereoscopic effect in the state in which an LED is turned off. However, as shown in FIG. 9B, the stereoscopic cover portion can provide not only the stereoscopic effect but also unique illumination in the state in which the LED is turned on.
