Description
技术领域technical field
本发明涉及液晶显示领域，具体涉及一种具有快响应时间的液晶组合物。The invention relates to the field of liquid crystal display, in particular to a liquid crystal composition with fast response time.
背景技术Background technique
负性液晶最早于上世纪80年代末提出，其主要用于VA模式，VA显示模式具有非常优异的对比度性能，但是存在明显的视角问题和响应时间问题，为了解决视角问题，MVA、PVA、CPA等显示技术提出，这些技术的本质在于利用多畴解决视角问题，并且取得了良好的效果。但是由于工艺上增加的难度和响应时间问题任然困扰着显示器行业，直至PSVA(聚合物稳定垂直配向)技术提出，该技术利用聚合物来实现多畴和预倾角控制以实现快响应和宽视角的液晶显示器。Negative liquid crystal was first proposed in the late 1980s. It is mainly used in VA mode. The VA display mode has excellent contrast performance, but there are obvious viewing angle problems and response time problems. In order to solve the viewing angle problem, MVA, PVA, CPA The essence of these technologies is to solve the viewing angle problem by using multiple domains, and good results have been achieved. However, due to the increased difficulty in the process and the problem of response time, the display industry was still plagued until the PSVA (Polymer Stabilized Vertical Alignment) technology was proposed, which uses polymers to achieve multi-domain and pretilt angle control to achieve fast response and wide viewing angle. LCD display.
可聚合单体存在于液晶中导致液晶的电压保持率下降，所以在液晶显示器生产工艺中需要添加工序将残余的可聚合单体充分反应，为了保证充分反应，时间通常较长，导致工艺时间拖长，造成产能降低；另一方面，由于前序工艺完成后需要等待，玻璃基板需要在环境中暴露一段时间，环境中的污染源污染面板表层，导致液晶显示器品质下降。液晶显示器的响应时间取决于液晶材料的旋转粘度，降低液晶组合物的旋转粘度可以实现快速响应时间的目的。The presence of polymerizable monomers in the liquid crystal leads to a decrease in the voltage holding ratio of the liquid crystal, so in the liquid crystal display production process, it is necessary to add a process to fully react the residual polymerizable monomers. On the other hand, the glass substrate needs to be exposed to the environment for a period of time due to the waiting time after the completion of the pre-process, and the pollution source in the environment contaminates the surface layer of the panel, resulting in the deterioration of the quality of the liquid crystal display. The response time of the liquid crystal display depends on the rotational viscosity of the liquid crystal material, and reducing the rotational viscosity of the liquid crystal composition can achieve the purpose of fast response time.
