Definitions

  • the present invention relates to the field of display technologies, and in particular, to a quantum dot liquid crystal display device.
  • Quantum Dots are usually spherical or spheroidal semiconductor nanoparticles composed of II-VI or III-V elements, and the particle size is generally between several nanometers and several tens of nanometers. Since the particle size of QDs is smaller or closer to the exciton Bohr radius of the corresponding bulk material, a quantum confinement effect is generated, and the energy level structure changes from quasi-continuous of the bulk material to discrete structure of the quantum dot material, resulting in special QDs. The performance of stimulated radiation.
  • the bandgap of the energy level increases, the energy required for the corresponding QDs to be stimulated, and the energy released by the QDs after returning to the ground state are correspondingly increased, which is manifested by the excitation and fluorescence spectra of QDs.
  • the "blue shift" phenomenon by controlling the size of the QDs, allows the luminescence spectrum to cover the entire visible region. For example, the size of cadmium selenide (CdSe) is reduced from 6.6 nm to 2.0 nm, and its emission wavelength is "blue shifted" from the red light region 635 nm to 460 nm in the blue light region.

Description

量子点液晶显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种量子点液晶显示装置。
背景技术
随着显示技术的不断发展，人们对显示装置的显示质量要求也越来越高。量子点(Quantum Dots，简称QDs)通常是由Ⅱ-Ⅵ、或Ⅲ-Ⅴ族元素组成的球形或类球形的半导体纳米微粒，粒径一般在几纳米至数十纳米之间。由于QDs的粒径尺寸小于或者接近相应体材料的激子波尔半径，会产生量子限域效应，其能级结构从体材料的准连续变为量子点材料的离散结构，导致QDs展示出特殊的受激辐射发光的性能。随着QDs的尺寸减小，其能级带隙增加，相应的QDs受激所需要的能量以及QDs受激后回到基态放出的能量都相应的增大，表现为QDs的激发与荧光光谱的“蓝移”现象，通过控制QDs的尺寸，使其发光光谱可以覆盖整个可见光区域。如硒化镉(CdSe)的尺寸从6.6nm减小至2.0nm，其发光波长从红光区域635nm“蓝移”至蓝光区域的460nm。
量子点材料具有发光光谱集中，色纯度高、且发光颜色可通过量子点材料的尺寸、结构或成分进行可简易调节等优点，利用这些优点将其应用在显示装置中可有效地提升显示装置的色域及色彩还原能力。如专利CN102944943A以及类似的专利均提出了用具有图案结构的量子点层置于显示面板的外侧替代彩色滤光膜(Color Filter)以达到彩色显示目的的技术方案。但是，若把量子点层设置在显示面板的外侧，外部自然光会对量子点进行激发，故在明亮的地方，显示器的对比度下降，并且有可能产生色偏的现象。当外部较为明亮时，外部光对其激发造成对比度下降，甚至色偏。
专利CN203204189U提供了一种单向导光膜材，通过在表面设置突棱，利用全反射的原理实现单向导光的作用，若把此种单向导光膜材置于显示面板的外侧，可以很好防止量子点层被外界光激发，从而提高显示面板的对比度，防止色偏；但是，这层单向导光膜材会导致显示器外表面的反射增加，进而会造成反光影像重影和眩光刺眼等影响观看者观看体验的现象。
