The combination of light‐emitting diodes (LEDs) and rare earth (RE) phosphors as color‐
converting layers comprises the basis of solid‐state lighting. Indeed, most LED lamps …

A new flexible nanocomposite substrate is reported to enhance the light outcoupling
efficiency of white organic light‐emitting diodes (OLEDs). The substrate comprises silver …

We demonstrate high-performance down-conversion microlens array (DC-MLA) films for
white organic light-emitting diodes (OLEDs). The DC-MLA films are readily fabricated by an …

In the study, the solution-processed PEDOT: PSS hole injection layer was treated by polar
solvent vapor annealing (PSVA) to optimize the carrier transport and light extraction. The …

We have demonstrated color stable white organic light-emitting diodes (WOLEDs) with
bipolar mixed spacer based on ultrathin non-doped phosphorescent emitting layers (EMLs) …

Aspheric microlens arrays (MLAs) are introduced on glass substrate to improve the light out-
coupling efficiency (LOCE) of organic light-emitting diode (OLED). Geometric ray tracing was …

For full-color displays, white organic light-emitting devices (OLEDs) combining with color
filters are a promising technology. It avoids the precise shadow masking that is often used to …

A theoretical model based on ray optics is used to simulate the optical performance of
organic light-emitting diodes (OLEDs) with spheroidal microlens arrays (MLAs) in a …

In this paper, we presented a new method to directly fabricate 3D microlens array (MLA)
without the pattern transfer and substrate reshaping process. Gas-assist deformed concave …

In this paper, efficient phosphorescent white organic light-emitting diodes (WOLEDs) were
fabricated based on ultrathin doping-free emissive layers and mixed bipolar interlayers. The …
