Organic Polymer Light-Emitting Devices on a Flexible Plastic Substrate
نویسندگان
چکیده
We report on the opto-electronic properties of red, green, and blue poly (fluorene) co-polymer light-emitting devices (PLEDs) fabricated on a flexible plastic substrate. The plastic substrate used has a multi-layer structure with water vapor and oxygen transmission rates of less than 10 g/cm-day-atm and 10 cc/cm-day-atm, respectively. We obtained a wide range of color gamut and a maximum emission efficiency of 0.7, 10, and 1.7 cd/A for red, green, and blue PLEDs, respectively. Finally, a simple equivalent circuit model is proposed to simulate PLED current density-voltage characteristics.

Stable intrinsic white light–emitting diodes were fabricated from c-axially oriented ZnO nanorods (NRs) grown at 50 C via the chemical bath deposition on top of a multi-layered poly(9,9-dioctylfluorene-co–N-(4butylpheneylamine)diphenylamine)/poly(9,9dioctyl-fluorene) deposited on PEDOT:PSS on highly flexible plastic substrate. The low growth temperature enables the use of a variety of flexible ...

The goal of this thesis is to achieve flexible full color AMOLED displays on clear plastic substrates using high temperature amorphous-silicon TFT’s. Dry dye-printing and solvent-enhanced dye diffusion were used to fabricate side-by-side red, green and blue organic light emitting device (OLED) pixels. The technique was then used to make combined polymer/small molecule devices, in which the prin...
