Description

一种应用于OLED领域的材料
技术领域
本发明涉及OLED领域,尤其涉及一种应用于OLED领域的材料。
背景技术
TFT-LCD作为一种显示屏,是一种非自发光之显示器,必须透过背光源投射光线,依序穿透TFT-LCD面板中之偏光板、玻璃基板、液晶层、彩色滤光片、玻璃基板、偏光板等相关零组件,最后进入人之眼睛成像,达到显示之功能。在实际应用中,TFT-LCD显示屏具有反应速率慢、耗电、视角窄等缺点,不足以成为完美的显示屏。
OLED,作为一种新型显示技术,具有自发光的特性,采用非常薄的有机材料涂层和玻璃基板制备得到。当有电流通过时,这些有机材料就会发光。目前,OLED的基本结构如三明治的结构,整个结构层中包括空穴传输层(HTL)、发光层(EL)与电子传输层(ETL)。当电力供应至适当电压时,正极空穴与阴极电荷就会在发光层中结合,产生光亮,依其配方不同产生红、绿和蓝三原色,构成基本色彩。由于OLED的特性是自己发光,因此,可视度和亮度均高,其次是电压需求低且省电效率高,加上反应快、重量轻、厚度薄,构造简单,成本低等,被视为21世纪最具前途的产品之一。
事实上,虽然OLED应用范围的不断扩大,但仍然存在不足,而决定OLED性能优劣的基本因素之一还是材料问题,因此,设计与合成一种新型OLED材料以克服其在实际应用过程中出现的不足,是OLED研究工作中的重点。
