“…Hence, the transmittance can be electrically switched. Additionally, IPS modes using positive dielectric anisotropy LCs in homeotropic alignment layers were also developed by Hyundai [29] and Samsung [30]. To overcome the dark lines, existing between the electrodes, Hyundai and Samsung groups proposed different approaches to achieve fourdomain configurations.…”

Nowadays, in your daily lives, the applications of LCs, such as LCD TVs, computer/laptop monitors, mobile phones, navigators, digital cameras, and so on, are widely used worldwide. Even, wherever you are whatever you do, you can take your electronics out of your pocket to check your e-mails, listen to music, watch movies, find your way, and so many others. LCDs provide high performance in regard to the weight, volume, contrast ratio, viewing angle, low power consumption, etc. That's why the high-quality applications of LCDs are indispensable and paid much attention by scientists and electronics industries in the recent decade. Undoubtedly, LCDs have acted as a leader in the field of flat panel displays, in not only small-sized displays, but also large-sized ones. Refer to cathode ray tube (CRT) monitors; LCDs have almost completely replaced CRT monitors in the display market because of their bulky and high power consumption, despite their good response time, viewing angle, image quality. However, in addition to the present status of LCD applications, some emerging technologies, such as wide viewing angle displays, fast response displays, blue phase LCDs, flexible displays, 3D displays, high resolution displays, in-cell touch panel, electronic papers, tablets, etc., have also attracted much attention. In this chapter, the introductions of the present status of LCD industry, as well as the emerging technology for improving the performances of LCDs will be given. Liquid Crystal Display ModesRegarding the commercial products of LCDs [1-3], their operating principles for modulating light intensity and/or light polarization include polarization

“…[10] To overcome this problem, Lee et al suggested a vertically aligned in-plane switching (VA-IPS) mode. [11][12][13] In the VA-IPS mode, the positive Δε LC was VA at zero field state and switched by in-plane electric field using interdigitated electrodes on the bottom substrate. Using this combination, the VA-IPS mode has been expected to show faster response than the twisted nematic (TN) and VA modes.…”

We investigated the effect of the polarisation direction and incident angle of a UV light on the electrooptical properties of the polymer-stabilised vertically aligned in-plane switching (PS-VAIPS) liquid crystal. The PS-VAIPS sample cured with a UV light whose polarisation was parallel to the projected direction of the inplane electric field showed greater transmittance, faster rising time and slower falling time than the sample cured with a UV light with a perpendicular polarisation to the electric field. In addition, the PS-VAIPS sample showed slower rising time and faster falling time with increasing incident angle of the UV light.

“…The required characteristics for liquid crystalline materials are low driving voltage and quick response, and wide viewing angle. The viewing-angle dependency has been significantly improved through new display technologies, namely the vertical alignment (VA) modes [1][2][3], applying liquid crystalline materials with large negative dielectric anisotropy (De).…”

A series of novel liquid crystalline compounds with a tetrahydropyrane ring were synthesized, and the physical properties have been measured. The compounds showed peculiar dependency of the dielectric anisotropy value on the connecting position of the tetrahydropyrane ring. This positional dependency is discussed with the measurement of the temperature dependency of the dielectric constants, and the semi empirical quantum calculation. In accordance with the experimental result, it was found that the difference of the dielectric anisotropy value is influenced by the difference of the dipole moment value and the direction of the dipole at the most stable conformation.
