OLED DEVICE HAVING IMPROVED LIGHT OUTPUT
First Claim
1. An organic light-emitting diode (OLED) device, comprising:
- a transparent substrate;
one-or-more transparent thin-film transistors located over the substrate;
one or more light-emitting elements formed over the transparent thin-film transistors, wherein each light-emitting element comprises;
a first transparent extensive electrode formed at least partially over at least a portion of the one-or-more transparent thin-film transistors;
at least one layer of light-emitting organic material formed over the first transparent extensive electrode; and
a second reflective electrode formed over the at least one layer of light-emitting organic material;
a low-index layer formed between the first transparent extensive electrode and the one-or-more thin-film transistors, the low-index layer having a lower optical index than that of the layer of light-emitting organic material, the transparent thin-film transistors, and the transparent substrate; and
a light-scattering layer formed between the low-index layer and the second reflective electrode, or formed as part of the second reflective electrode.
