  In the past decade, display technology has been reimagined to meet the needs
of the virtual world. By mapping information onto a scene through a transparent
display, users can simultaneously visualize both the real world and layers of
virtual elements. However, advances in augmented reality (AR) technology have
primarily focused on wearable gear or personal devices. Here we present a
single display capable of delivering visual information to observers positioned
on either side of the transparent device. This dual-sided display system
employs a polymer stabilized liquid crystal waveguide technology to achieve a
transparency window of 65% while offering active-matrix control. An early-stage
prototype exhibits full-color information via time-sequential processing of a
red-green-blue (RGB) light-emitting diode (LED) strip. The dual-sided display
provides a perspective on transparent mediums as display devices for
human-centric and service-related experiences that can support both enhanced
bi-directional user interactions and new media platforms.
