Jun-Yu Huang Modeling of carrier transport in Organic Light Emitting Diodes by 2D Random Doping Model
Jun-Yu Huang;Te-Jen Kung;Yuh-Renn Wu

Poisson and drift-diffusion solver is used with effective density of state and Poole-Frenkel mobility model to simulate OLEDs. Influence of doping density to the effective field dependent mobility was predicted with 2D random dopant model and was successfully applied to 1D simulation. Different doping to transport is well modeled.

Amanuel Assefa Kassa Simulating Organic LED strips for lighting and VLC
Amanuel Assefa Kassa;Po-Jui Chen;Xuan Long Ho;Jonathon David White

Organic LED strip lighting, with picosecond fluorescent lifetimes, is shown to simultaneously provide high quality uniform shadow-free diffuse lighting at low cost while allowing Visible Light Communication speeds of 0.3-0.6 Mbps without filters for a 5x5x3m3 room.

Bo-Lin Huang Simulation of Localized Surface Plasmon Resonance in Organic Light Emitting Diodes by Random Particle Model
Bo-Lin Huang;An-Chi Wei

This research studies the effect of localized surface plasmon resonance (LSPR) for enhancing the OLED luminous efficiency. We build an electromagnetic wave model with random particle distribution and simulate the absorption spectrum of OLED to optimize the structure of the nano-particle layer.

Tzo-Guo Hu Optimal LED Spectra
Tzo-Guo Hu;Tsung-Hsun Yang;Yeh-Wei Yu;Ching-Cherng Sun

We have successfully obtained the optimal LED spectra of the highest CRI for warm and cool white. By an empirical spectral function describing the LED spectra with high accuracy, the optimal LED spectrum can be easily evaluated. The optimal LED spectra for the highest CRI of various CCTs is concluded.

Jun-Yi Wu Achromatic Design of Packaging Lens in White Light LED
Jun-Yi Wu;Shih-Hsin Ma

In this study, the white light LED with an achromatic packaging lens which is composed by three different mediums is proposed. The shapes of the interfaces in the packaging lens are designed. According to the results of design, the achromatic packaging lens can reduce the color dispersion obviously.
