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.

An optical laminate is provided. When the optical laminate is applied to an OLED display device, the problem of visibility due to reflection of external incident natural light of the device can be solved, and simultaneously its display quality can also be improved.

A comprehensive system and method construction of an organic lighting diode (OLED) display for regular outdoor use. In one embodiment, the system includes an OLED display that includes an OLED panel with a front side and a back side, a front cover glass with an optional controllable UV light blocking medium coupled to the front side of the OLED panel, a rear cover coupled to the OLED panel. The incorporation of a controllable UV light blocking medium—such as electrochromic (EC) glass, Suspended Particle Device Film (SPD), Polymer Dispersed Liquid Crystal (PDLC) or any other equivalent controllable tinting technology bonded to the front side of the OLED panel—allows the display to protect itself from excess light. The UV light blocking medium can be controlled programmatically, by implementing light sensors, timers or by manual control via a switch or similar device.

Disclosed herein are light emitting device that emit highly circularly polarized light. These devices may be used to form a dot-matrix display or an electronic information display comprised of a series of photopolymerizable, chiral liquid crystalline layers that can be solvent cast on a substrate. The mixture of chiral materials in each successive layer may be blended in such a way that each layer has the same chiral pitch and may also be blended so that the ordinary and extraordinary refractive indices in each layer match the other layers such that the complete assembly of layers will optically function as a single relatively thick layer of chiral liquid crystal. The chiral nematic material in each layer can spontaneously adopt a helical structure with a helical pitch. Further disclosed are pixel structures that not only emit light with brightness and chromaticity information, but also depth of focus information as well.
