What is CSTN LCD ( Color Super Twisted Nematic LCD )  ?

      In fact ,color STN Technology is STN technology that uses a white back light and color filters to deliver the tones needed for a color display. Every visual pixel of a CSTN display is really physically 3 different pixels utilizing a red/green/blue colored filter! Each of those colors are controlled separately by graphic IC. So in fact,a 320*240 pixel CSTN display really includes 960*240 exclusively colored pixels.
