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.
Definition of:IPS panel. (I n-P lane S witching panel) An active matrix (TFT) LCD screen technology developed by Hitachi in the mid-1990s that provides more uniform color reproduction and greater viewing angles than traditional twisted nematic (TN) LCDs.Maturing for more than a decade, IPS was deployed in iPads and various Android tablets.hen energized, the liquid crystals in an IPS screen twist in the same plane (in plane) as the panels. In the ubiquitous twisted nematic (TN) display, the crystals become more perpendicular to the top panel. See LCD subpixels.
