Evaporated receptacles for inkjet deposited polymeric light-emitting diode (PLED)/organic light-emitting diode (OLED) and a method of making the same. The evaporated receptacles are formed via a shadow mask vacuum deposition process. The method of forming a light-emitting display includes forming an electrode on a substrate, forming a receptacle structure over the electrode via a shadow mask vacuum deposition process, and delivering a quantity of polymeric solution, which contains a light-emitting material, into the receptacle via a standard inkjet deposition process.

Receptacles for inkjet deposited PLED/OLED devices and method of making the same

A system and method for improving light extraction from luminescent devices such as light-emitting flat-panel displays (for example, light-emitting diode (OLED) flat-panel displays) or flat panel lamps. The system includes a material with negative index of refraction, preferably with n=&#x2212;1. The presence of such material on the exit surface of the electro-optic devices such as flat panel display or lamp with light-generating medium sandwiched between materials with refractive index n&#x3e;1 fully removes TIR and results in light outcoupling efficiency of about 100%.
