有机电致发光器件发展及展望综述

中文摘要

有机电致发光器件(organic light-emitting device, OLED)目前已成为平板信息显示领域的一个研究热点。OLED具有平板化、自发光、色彩丰富、响应快、视野宽及易于实现超薄轻便等优点,被认为是未来最有可能替代液晶显示器和等离子显示器的一种新技术,同时可以用做照明和背光源。但是,其制作成本高、良品率低等不足有待解决。OLED显示技术与传统的LCD显示方式不同，无需背光灯，采用非常薄的有机材料涂层和玻璃基板，当有电流通过时，这些有机材料就会发光。而且OLED显示屏幕可以做得更轻更薄，可视角度更大，并且能够显著节省电能。

为了形像说明OLED构造，可以将每个OLED单元比做一块汉堡包，发光材料就是夹在中间的蔬菜。每个OLED的显示单元都能受控制地产生三种不同颜色的光。OLED与LCD一样，也有主动式和被动式之分。被动方式下由行列地址选中的单元被点亮。主动方式下，OLED单元后有一个薄膜晶体管（TFT），发光单元在TFT驱动下点亮。主动式的OLED比较省电，但被动式的OLED显示性能更佳。

Abstract

Electroluminescent devices (organic light-emitting device, OLED) flat panel information display has become a hot topic in the field. OLED technology has a flat, self-luminous, rich colors, fast response, wide horizons and easy to implement the advantages of ultra-thin light, is considered the next best possible alternative to liquid crystal displays and plasma displays, a new technology while can be used as lighting and backlight. However, its high production cost, low rate of less than good product to be resolved. OLED display technology with the traditional LCD display in different ways, no backlight, with a very thin coating of organic materials and glass substrate, when a current is passed, these organic materials will be light. OLED display screen can be done but lighter and thinner, larger viewing angle, and can significantly save power.

To image shows OLED structure, each OLED element can be likened to a hamburger, light-emitting material is sandwiched in between the vegetables. Each OLED display unit can be controlled to produce three different colors of light. OLED and LCD as well

as active and passive distinction. Passive mode selected from the ranks of the unit address to be lit. Active mode, OLED module has a thin film transistor (TFT), light-emitting unit in the TFT-driven light. More active in OLED power, but the passive OLED display performance better.
