Fabrication of led
WebMay 2, 2010 · Organic light-emitting diode (OLED) represents an alternative to conventional III–V compound LED because it can be fabricated on flexible substrate with large area by solution process [1,2]. The first OLED was reported by Tang and Van Slyke in 1987 using a simple bilayer structure sandwiched between two electrodes [3]. Web1 Introduction. Light emitting diodes (LEDs) were developed around 50 years ago, initially for application as indicators and low resolution monochromatic displays. [] With improvements in both material (including demonstration of blue-green devices using III-N materials in the early 1990s), [] fabrication and packaging, these devices are now the preferred …
