LCD
"LCD" is an acronym for liquid crystal display, which refers to a type of monitor that uses light-emitting diodes to create colours instead of cathode ray tubes (CRTs) that project electrons onto a fluorescent screen to create colours.
That is why LCD displays are substantially flatter than CRTs.
That is also why LCD displays are used in notebook computers, as well as in pocket calculators.
There are passive displays (DSTN) and active displays (TFT). The main difference between these two displays is that the active display has a transistor for every pixel that determines that pixel's behaviour.
While the passive version has a lower display quality, passive displays used to be an inexpensive alternative to the expensive TFT displays. However, passive displays are hardly used anymore these days.
The quality difference is most apparent when the display is viewed at a very oblique angle: The colours distort very quickly.
One disadvantage that was associated with LCD displays for a long time was the "residual lighting period", that is, the smudging of the screen display.
That is why such screens could not be used for playing games. However, today's technology has advanced to the point where LCD displays can be used for playing games without problems.
A major advantage of LCD displays is that they do not flicker at all:
As long as the graphic card does not send a new image, the existing image remains "intact".
However, this does not mean that LCD displays are completely stable. Still, with an LCD display, the graphic card need only create 60 images per second (60 Hz) for a display that is completely free of flickers, while a CRT displays needs at least 75 Hz to create a display of the same quality and stability.
