The production of polymer‐stabilized vertically aligned (PSVA) displays requires two UV processes for liquid crystal (LC) alignments. UV1 is usually short for pre‐tilt angle formation, while UV2 takes approximately 90 minutes to consume the remaining reactive monomers (RMs). Therefore, shortening the UV2 process can significantly reduce the power consumption and maintenance costs of UV lamps during LCD fabrication. Herein, we report a novel LC material consisting of fast‐reaction RMs. With the addition of fast‐reaction RMs, the UV2 process can be dramatically decreased from 90 min to 20 min. Furthermore, the reduction of the UV2 process shows competitive optical properties, reliabilities and pre‐tilt angle stabilities compared with the reference. Overall, new fast‐reaction LC materials are beneficial to energy saving and the cost competitiveness of the company. [ABSTRACT FROM AUTHOR]

Methoxy‐bridge polar monomer has high dielectric anisotropy, which can reduce the driving voltage of the panel and save energy; olefinic‐chain monomer can effectively reduce the rotational viscosity and improve the response speed of the panel, while the polar alkene monomer has both low rotational viscosity and high dielectric anisotropy, which has a good application prospect. At present, the industry does not have too much verification and analysis of the collocation about the collocation of two monomers. In this paper, the reliability of liquid crystal materials containing polar methoxide monomers and polar alkene monomer was tested. The results showed that VHR (Voltage Holding Ratio) performance was worse in the experimental group with the two monomers. And with the extension of UV irradiation time, the difference between the experimental group and the control group was more obvious. A further test of IS (Image Sticking) was conducted on a 32‐inch display platform. The results showed that the liquid crystal containing both two monomers was tested NG, while the control group was OK. [ABSTRACT FROM AUTHOR]

The demand for fast response liquid crystals (LC) with high reliability for high performance liquid crystal displays (LCD) is increasingly urgent. In this work, the relationships between the conditions of the UV process and the reliability of fast response LC were investigated. By the application of novel reactive monomers (RM) with faster polymerization rate and longer reaction wavelength, a kind of fast response LC with high voltage holding ratio (VHR) and low ion concentration has been obtained. This work provides new insights for the improved reliability of fast response LC without electro‐optical performance loss. [ABSTRACT FROM AUTHOR]

Polyimide‐free technology is a technology in which an additive can replace polyimide film to align LC molecules. In this technology, the additive added in liquid crystal (LC) host can not only affect the alignment behavior, but also affect the reliability of the panel, such as image sticking. Because the polymer is polymerized from the additive in LC, the system of the additive is very important. In this paper, we studied the alignment and image sticking performance fabricated by two different additive systems:1. the mixed system of additive and reactive monomer; 2. the single additive system. From the results of cell and 28" panel, we can conclude that the mixed system has similar alignment ability and voltage holding ratio to the single additive system, however, has better image sticking performance than the single additive system.
