量子点液晶显示器 技术领域
本申请涉及显示技术领域，尤其涉及一种量子点液晶显示器。
 背景技术
目前由于量子点材料(Quantum Dot，QD)本身所具有的高色纯度、光谱连续可调等优异性质，使其成为21世纪最为优秀的发光材料，可以在显示色域上大幅度提高现有LCD的色彩表现，因此近年来其显示应用被广泛研究。现有的QD-OC（量子点液晶显示面板）具有视角极大，色域较高的优势。但是量子点液晶显示面板的能效较低，成本较高。研究发现量子点膜层贴近背光发光效率最优，因此量子点导光板作为背光源的理论激发效率最高。但由于树脂体系对量子点膜层的分散性的限制，量子点膜层的厚度较高，且网印量子点膜层的网点的量子点导光板结构无法达到背光模组的亮度要求。以上这些都缺陷限制了量子点液晶显示面板、量子点导光板的产业化应用。
综上所述，现有的量子点液晶显示器，由于量子点液晶显示面板激发效率低的原因，较难达到理想的高色域、广视角、高能效要求，进一步导致显示效果不佳。
