A review on fabrication process of organic light emitting diodes

Light emitting diodes (LEDs) have been dominating over years in the realm of incandescent and fluorescent lighting due to their long life, intensity and power efficiency. But having certain limitations like difficulty and cost of production, they have been being restrained from conspicuous application. Organic Light Emitting Diode (OLED) nowadays is a promising feature over Liquid Crystal Display (LCD) and other lighting appliances, due to their low cost, ease of fabrication, brightness, speed, wide viewing angle, low power consumption and contrast. Edging ahead, OLED also facilitates further LED market permeation. This paper discusses the structure of OLED, working principle and operation, fabrication and recent advances made in the area as ease of fabrication process is the singular most important benefit over alternative technologies.
