Abstract: Disclosed herein are head-mounted and other display assemblies that utilize organic light emitting diodes as image sources. In the organic light emitting diodes utilized in these display assemblies light is emitted by stimulated emission. As a result of this, the organic light emitting diodes utilized emit light vertically within a narrow cone about axes normal to the planes of the organic light emitting diodes. This narrow cone of emission results in greatly reduced light insertion losses when light transits from the organic light emitting diodes through the display assemblies and as a result increased energy efficiency in the operation of the display assemblies.

The silicon transistors, semiconducting-transistors, and capacitors may have control terminals that are coupled to gate or routing lines that extend across the face of the display and that are formed in a low resistance source-drain metal routing layer.
