Abstract:
A communication device with a dual-sided liquid crystal display, comprising:a housing for holding the display, the housing having a first side with a first viewport and a second side with a second viewport; a liquid crystal panel with an associated driver circuit, the panel having a first side for viewing a top portion of the display from the first viewport and a second side for viewing a bottom portion of the display from the second viewport; a top reflective layer disposed on the top portion of the panel on the second side of the panel; a bottom reflective layer disposed on the bottom portion of the panel on the first side of the panel; and a processor coupled to the driver circuit, wherein the processor directs the display through the driver circuit to provide user interface information for operating the communication device, and wherein the reflective layers are holographic elements optically coupled to the panel such that light traversing the top portion of the panel from the first side to the reflective layer on the second side is reflected back towards the first side and light traversing the bottom portion of the panel from the second side to the reflective layer on the first side is reflected back towards the second side.
