A STN (super-twisted nematic) display is a type of liquid-crystal display (LCD). An LCD is a flat-panel display that uses liquid crystals to change its properties when exposed to an electric field, which can be used to create images. This change is called the twisted nematic (TN) field effect. Earlier TN displays twisted the liquid crystal ...
The twisted nematic (TN) display is one of the oldest and frequently cheapest kind of liquid crystal display technologies. TN displays have fast pixel response times and less smearing than other types of LCDs like IPS displays, but suffer from poor color reproduction and limited viewing angles, especially in the vertical direction. When viewed ...

Tennessee closed the game on a 17-13 run to secure the win and set the second-seed Vols up with a showdown against No. 1 seed Purdue in the Midwest regional final.
Apart from his pioneering work on the TN-effect (i.e.e twisted nematic field effect), novel liquid crystal materials, organic semiconductors and biophysics, he invented or co-invented the following effects and technologies: first organic light-emitting diode (OLED) (1969 as post-doc at Canada's NRC; US patent 3,621,321), Kerr effect in LCs (1972),
DSTN (double super twisted nematic), also known as dual-scan super twisted nematic [1] or simply dual-scan, is an LCD technology in which a screen is divided in half, which are simultaneously refreshed giving faster refresh rate than traditional passive matrix screens. [2]
The molecules are reoriented by an applied electric field, while remaining essentially parallel to the surfaces to produce an image. It was designed to solve the strong viewing angle dependence and low-quality color reproduction of the twisted nematic field effect (TN) matrix LCDs prevalent in the late 1980s. [1]
The liquid crystal alignment is chosen so that its relaxed phase is a twisted one (see Twisted nematic field effect). [8] This twisted phase reorients light that has passed through the first polarizer, allowing its transmission through the second polarizer (and reflected back to the observer if a reflector is provided).
