Controlling the emission properties of organic light emitting diodes by bulk-heterojunction organic photodiode

摘要：

In this paper, we have studied the emission properties of organic light-emitting diodes (OLEDs) controlled by organic photodiode devices based on poly-3-hexylthiophene (P3HT) and 6,6-phenyl-C61 butyric acid methyl ester (PCBM) for high-contrast display applications. We exhibit the changes in the current and luminance of an OLED as a function of time when different illumination power was exposed to the organic photodiode. The luminance of an OLED was increased from 52cd/m2 to 685cd/m2 when the organic photodiode was exposed to different illumination power under the light intensity from dark condition to 500mW/cm2 using a xenon lamp. As a result, with such power recycling, the devices themselves would have the added self-powering function and the higher system-level power efficiency.
