→Contrast Ratio
The picture quality of plasma and LCD is very similar but plasma panels are known for their better contrast ratios, rendering of rich colors and deeper blacks. Plasma screens are available in larger sizes and have a better refresh rate, which makes them better for action viewing and sports with little to no ghosting effects. Plasma screens can suffer from burn-in caused by static images such as logos down in the corner.
However, LCDs are taking have taken over the market and are made in a wider range of sizes than plasma screens. The sweet spot targeted by LCD manufacturers is 42 to 50 inches. LCDs can show ‘ghosting’ trailing after a fast-moving image.
The viewing angle of both is similar. The image quality of a plasma TV is good when viewed off to the side; whereas an LCD TV will lose contrast or brightness. This is an important consideration in a salon with fixed furniture. But overall, LCDs are up to four times brighter.
