    Abstract: Novel emissive display module and an emissive display assembly are disclosed. The emissive display module and the emissive display assembly incorporate a photo-switchable polarizer that is switchable between an active, polarizing, state and an inactive, non-polarizing, state depending on the predetermined level of intensity of UV light in the ambient light and enhance the viewable quality of the emissive display by minimizing or eliminating UV light reflection on the emissive display.

    Abstract: An organic light emitting diode (OLED) architecture in which efficient operation is achieved without requiring a blocking layer by locating the recombination zone close to the hole transport side of the emissive layer. Aryl-based hosts and Ir-based dopants with suitable concentrations result in an efficient phosphorescent OLED structure. Previously, blocking layer utilization in phosphorescent OLED architectures was considered essential to avoid exciton and hole leakage from the emissive layer, and thus keep the recombination zone inside the emissive layer to provide high device efficiency and a pure emission spectrum.
