报告摘要：

在平面显示的实际应用中，视觉对比要比图像亮度更重要。然而，提高有机发光二极管的视觉对比面临着巨大挑战。本报告主要介绍有机发光二极管中通过梯度折射透明电极设计来加强视觉对比的最新研究进展，其原理是梯度折射透明电极可以降低有机发光二极管中周围光的反射。同时，梯度折射透明电极在薄膜蒸镀过程中容易制备和优化，为高视觉对比有机发光二极管显示的应用降低了成本。

Abstract:

In practical applications, the visual contrast of an emissive display is more important than the brightness of image. As such, improving the visual contrast in organic light-emitting diodes (OLEDs) is another important issue to address with a significant technological implication. This talk will discuss the progress in developing gradient refractive index transparent electrode for enhancing the visual contrast in OLEDs. The concept is based upon on using an electrode with a gradient or graded refractive index to minimize the ambient light reflection from OLEDs and hence to enhance the visual contrast. The transparent electrode with gradient refractive index can be easily engineered and optimized during the film deposition, providing a cost-effective approach for application in high contrast OLED displays.
