摘要

传统的显示器由于滤色器的存在，有较大的功耗且能量利用率不高。本文提出了一种利用液晶调制紫外光偏振态以实现对受到局域表面等离子体共振影响的荧光量子点光强调制的方法，所设想的显示设备由用于产生局域表面等离子体共振的金属纳米结构、附着于金属纳米结构电场热区的荧光量子点和基于液晶结构的光偏振调制模块组成。对单个像素的情况进行了理论模拟和原理分析，计算了若干金属纳米结构对不同偏振态的紫外光的响应。理论验证了特定金属纳米结构的表面等离子体光强放大效应，通过电子束刻蚀和半导体沉积等技术手段可在光强放大的电场热区植入荧光量子点，受到紫外光偏振态调制的金属表面等离子体产生可控的光强增强或减弱，进而激发或者抑制相应颜色的量子点发出不同颜色的光，使其可以用于显示。提出了一种新颖的显示模式，不同于传统显示，其具有较高的能量利用率和较大的色域，虽然其存在色彩对比度较低、分辨率不够高等问题，但提议确实为人们日常的信息显示提供了一种新的思路和一种潜在可能，相信随着技术的进步和设计结构的优化，这种光偏振态调制受表面等离子体激励的荧光量子点的方法可以在显示以及非显示领域获得应用。

Abstract

Due to the existence of color filter， the traditional displays have large power consumption but relatively low efficiency. In this article， we propose a method to utilize the polarization of an ultraviolet light， which is modulated by liquid crystal， to influence the light intensity distribution of a designed nanostructure in order to tune the stimulated fluorescent light of the quantum dots deposited in the corner of the metallic nanostructure. The concept is fundamentally based on the polarization-influenced local surface plasmon resonance and the proposed device comprises of the metallic nanostructure， quantum dots and liquid-crystal-based light polarization modulator. We simulate the electric field distribution for a single pixel case， and calculate the light intensity distributions for several metallic nanostructures under different polarization states of light. Thus， we theoretically verify the light intensity enhancement via local surface plasmon resonance arising from the specific metallic nanostructure. Through the technologies of E-beam etching and semiconductor deposition， the quantum dots with different sizes for corresponding colors can be implanted in specific “hot” areas， i.e.， the corner of the metallic nanostructure， whose stimulated emitting fluorescent light intensity can be controlled via light polarization modulation through liquid crystal module. Thus， we propose a novel display mode， which possesses relatively high efficiency and large color gamut. Although it currently encounters some unexpected issues such as relatively low contrast ratio and low resolution， our proposed device does provide a potential way for the information display in people’s daily life. We believe that with the development of the technology and the optimization of the device， the proposed device is promising in the field of display or beyond.
