“…To reduce such high operating voltage, several modified structures of IPS electrodes, such as protrusion electrodes [44], wall-shaped electrodes [45], double-penetrating fringe fields [38], and corrugated electrodes [36], are developed. Also, Kim et al and Wu et al also proposed vertical field switching (VFS), whose electric field is in longitudinal direction and uniform, in BP-LCs [40,46,47]. However, although BP-LCs were discovered a 100 years ago and were also improved technically, they were almost failed to be really applied for fabricating practical devices due to the described instinct shortages.…”

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

“…There is no viewing angle problem when a BPLCD is driven by an electric field, so there has been a shift in attention from a focus on in-plane-switching (IPS) to vertical-field-switching (VFS) [5][6][7][8][9][10]. Because there is no brightness by normal incident light, a VFS BPLCD needs an oblique incident light source that their configurations are complicated and costly in real manufacturing.…”

ABSTRCTWe propose a light guide plate of an oblique incident light source for a vertical-field-switching blue phase liquid crystal display. The LGP consists of a designed microstructure bottom surface and other specially microstructure top surface. We simulated the LGP of a backlight system by optical software (TraceProTM) and the performance of the BPLCD by liquid crystal software (TechWiz). The result shows that the output rays mainly emit at 59° and the uniformity is 78.84%. The designed applicable light guide plate successfully increase the angles of oblique light source and provide a better uniformity of illumination for a vertical-field-switching blue phase liquid crystal display.
