Default Types of Screens

I'm wondering what's the difference in these screen types? I assume TFT's the best way to go, but what the hell is STN/CSTN?

TFT
STN
CSTN

TFT(thin film transistor) is a type of LCD (liquid crystal display) flat-panel display technology.
Compared to other types of LCD technology, TFT features excellent image quality and response time, but uses more power, and is more expensive.
TFT: technology is an active-matrix technology, meaning that a tiny circuit (a transistor) is located next to each pixel, allowing the pixel to be turned on and off individually. This permits faster response time and greater contrast compared to passive-matrix technology.

STN: (Super Twisted Nematic) is a type of LCD (liquid crystal display) flat-panel display technology.
STN uses less power and is less costly than TFT technology, but at the expense of image quality and response time.
STN technology is a passive-matrix technology, meaning that each pixel must be "refreshed" individually many times each second. To accomplish this, the liquid crystal must react slowly enough to maintain state between refreshes. This keeps response times relatively low, and limits brightness and contrast.
CSTN: is basically an improved version.
