The role of the supervisor. Although a dissertation is an opportunity for you to work independently, you will usually be allocated a member of academic staff as a supervisor. Supervisors are there to help you shape your ideas and give you advice on how to conduct the research for your dissertation.
The TN device consists of the twisted nematic liquid crystal confined between two glass substrates with homogeneous planar orientation: the orientation of the director n on one substrate is rotated by 90 o with respect to n on another substrate.
IPS stands for in-plane switching and is used with LCD screens to form IPS-LCD, which is a thin display that solves limitations in TFT-LCDs. Some of the limitations of twisted nematic field effect matrix LCDs include low-quality color production and a dependency on viewing angle. IPS-LCDs, then, have better color reproduction and viewing angles.
