The present invention discloses a general, highly effective and scalable extraction-enhancing OLED display pixel structure based on embedding the OLED inside a three-dimensional reflective concave structure selectively filled with a high-index filler material. Such a structure is able to couple as much as possible internally generated photons into the filler region and then redirect otherwise confined light for out-coupling via the reflective concave structure. Ultimately high light extraction efficiency approaching ˜80% and excellent viewing characteristics are simultaneously achievable with optimized structures using highly transparent top electrodes. This scheme is scalable and wavelength insensitive, and thus can be generally applied to all red, green, and blue pixel OLEDs in high-resolution full-color displays.
