Hello hajo,
An LCD TV has liquid a crystal display panel, which is activated when an electric current is supplied to it. The LED TV works on the same liquid
crystal platform, but it has light-emitting diodes (LED) used as the back-light for the panel while the normal LCD TV uses a CCFL back-light. The LED back-lights allow for a thinner screen. A plasma TV works on a completely different platform. A plasma TV has plasma cells, which are activated when electricity is passed to the TV.
Contrast Ratio
Plasma TVâs are generally thought to have the better contrast ratios than LCD or LED. LED has a slight advantage to LCD where contrast ratio is concerned.
Viewing Angle
The image of the plasma TV remains good and solid for viewers at almost any angle. LCD generally lags behind plasma as there may be a loss of colour or detail at an angle. The LED TV has minimal problems with viewing angle compared to LCD due to its decentralized back-lights.
Color
There is no clear leader in colour comparison as all of these TVs good quality picture, when it comes to the colour. There will be differences between different models or brands.
Motion
Plasma screens have individual cells that can refresh at a faster rate, however LCD has improved greatly in recent years. A higher HZ rating will ensure better performance. LED televisions are much the same as LCD and therefore a higher HZ ensures better performance on fast motion sequences.
Power Consumption
LED tv is the most power efficient due to itâs LED back-lighting.
Thank you for choosing Sears.
