DOUBLE-SIDED DISPLAY

Abstract

A double-sided display comprises a first organic light emitting device with a first transparent substrate, and the first organic light emitting device illuminates toward the first substrate. A second organic light emitting device with a second transparent substrate opposite to the first substrate, and the second organic light emitting device illuminates toward the second substrate. The first organic light emitting device is separated from the second organic light emitting device by a gap. A controller, coupled to the first and second organic light emitting devices, receives a control signal to individually switch the power of the first and second organic light emitting devices.
