OLED-Display Technology

摘要

The development of lightweight displays with sharp saturated images, lower power consumption, and more compact dimensions than the cathode-ray tube (CRT) has been a key factor in enabling the growth of many portable electronic devices. The improvements in image quality and physical dimensions which these new display technologies have made possible also have made them attractive for non-portable electronic-imaging applications such as desktop computers and televisions. The liquid-crystal display (LCD) has been the dominant alternative to the CRT for the past 20 years, but a technology based on electroluminescent emission from thin solid films of organic materials has emerged as one of the most promising next-generation imaging technology. These organic light-emitting-diode (OLED) displays exhibit wide viewing angles and can be very light in weight because they do not require a backlight.
