There are two categories of LCDs then Before looking at what type of configurations you need to look for when purchasing a computer Flat Panel it is important to know if you want Active Matrix LCD or Passive Matrix LCD.
Active Matrix LCD : Active Matrix LCD uses a transistor for each liquid crystal cell or pixel and thus displays high quality images. Active Matrix LCD is also known Thin Film Transistor(TFT) display. Today, new generation of TFT is called organic LED that displays brighter images than standard TFT display. The organic LED uses organic molecules to generate output on the screen.
Passive Matrix LCD : Passive Matrix LCD uses fewer transistors and requires less power than active matrix LCD. The colors on Passive Matrix LCD are not bright as compared to active matrix LCD.
Resolution
The quality of LCD screen depends on its resolution, which is generally proportional to the size of screen.
15" flat panel monitor typically has a resolution of 800 x 600 / 1,024 x 768
17" flat panel monitor typically has a resolution of 1,280 x 1,024
19" flat panel monitor typically has a resolution of 1,280 x 1024
21" flat panel monitor typically has a resolution of 1,600 x 1,200.
