量子点显示及其技术趋势

Quantum Dots Display and Technology Trend

量子点是一种宽吸收、窄发射、荧光量子产率高的新型荧光材料,是优秀的显示用发光材料,研究量子点材料在显示技术上的应用有助于实现显示屏幕的高画质和轻薄化。随着人们对高色域显示的追求,量子点材料不仅会在液晶显示屏上大量应用,同时也将是有机发光材料的有力替代者,未来AMQLED将与AMOLED实现归一化发展。文章详细介绍量子点光致发光以及电致发光在显示技术上的多种应用,阐述量子点背光、量子点彩膜以及AMQLED等不同量子点显示技术的原理,并分析不同技术的特点及其发展趋势。

Quantum dots was a kind of new fluorescent material with wide absorption,narrow full width of half maximum and high quantity yield,fluorescence quantum efficiency.Studying on the application of quantum dots material would be helpful to realize high color gamut and ultrathin display screen.Multiple applications of the photoluminescence quantum dot and electroluminescence quantum dot in display were introduced,and the technical principles of display technology using QD-backlight,QD-CF,QLED were elaborated as well.The characteristics and development of different technologies were also analyzed.With the development of high color gamut in display,quantum dot materials will not only be widely used in LCD,but also be a powerful substitute for organic light-emitting materials.In the future,active light-emitting AMQLED display will develop synchronously with AMOLED and become the mainstream of the market.
