The twisted nematic effect (TN-effect) was a major technological breakthrough that made the manufacture of large, thin liquid crystal displays practical and cost competitive. Unlike earlier flat-panel displays, TN-cells did not require a current to flow for operation and used low operating voltages suitable for use with batteries.
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 ...
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),
Kevin Durant scored 30 of his 36 points in the second half and the Phoenix Suns defeated the Detroit Pistons 125-121 on Saturday. Devin Booker scored 35 points, his fifth consecutive 30-point ...
The Rams won the Super Bowl that season. Detroit went 3-13-1. Goff was considered a throw-in on the trade, but Campbell and general manager Brad Holmes believed in him when others didn’t.
