A switched emissive transparent display with controllable per‐pixel opacity

Abstract An emissive transparent display with per‐pixel opacity employs rapid synchronized switching of a transparent display and transparent backlight between content with a scattering luminous backlight and masks with a clear unlit backlight. A 144 fps transparent LCD panel is used in conjunction with a transparent backlight, controllably diffusive smartglass screen, and optional switching background lighting. The display is capable of producing opaque emissive content on a transparent field for novel transparent display and compact spatial augmented reality applications.
