One item that manufacturers don’t usually make a big deal about happens to be the aspect of any display that seems to matter most - LCD panel technology. There are three main categories of panel technology: TN (twisted nematic), MVA/PVA (multi-domain vertical alignment/patterned vertical alignment), and IPS (in-plane switching). Opinions about which technology is actually best differ somewhat, but there’s no denying the fact that TN is substantially cheaper to produce whereas PVA and IPS are more expensive. These days, the vast majority of LCD are once again using TN LCD panels, largely because of the pricing advantage. If you want a higher quality panel using MVA, PVA, or IPS you will need to be prepared to pay anywhere from 50% to 300% more, depending on overall quality.

Contrast Ratio Comparison Between LCD TV
Many LCD specifications are prone to inflation by the manufacturers or have become largely meaningless. Take contrast ratio for example. That’s the white level divided by the black level, and if you could actually get pure black on any LCD contrast ratio would be “infinity”. In practice, anything over 500:1 is sufficient, and 1000:1 is about the best you can see before the manufacturers start playing tricks. What sort of tricks? How about dynamic contrast ratio, where the backlight intensity changes according to the content currently being shown on the display.
