In the world of high-definition television (HDTV) there are essentially three options available: LCD (liquid crystal display), LED (light-emitting diode), or plasma. All three offer high-definition picture display, so how do you determine which one is best?
Is There a Difference?
Currently, the only real distinction between the three HDTV systems is found in functionality. Plasma TVs do not require an auxiliary backlighting source, because the screen is self lit by the phosphors contained in the TV. An auxiliary light source is required for LCD TVs to generate a visible picture. There are essentially two backlight sources for LCDs: CCFL and LED. CCFL is basically a fluorescent backlight. Using LED as a back light source is the most energy efficient option. LED backlighting also allows HDTVs to be brighter and thinner. The only downside is that LED TVs are currently the most pricy.
It is All About Preference
Basically, it comes down to your personal preference and TV needs, when it comes to deciding, which HDTV type is best for you. By definition, an LED TV is an LCD TV with a specific type of backlight. Because of this, the competition over which type of HDTV is best is narrowed down to the LED TV and the plasma TV. Some people say the LED is better, however, it comes at a price, as LED TVs are more expensive than plasma TVs. For the money, plasma TVs will fulfill most consumers’ needs.
In the end, the quality difference between LED TVs and plasma TVs is seemingly negligible. However, if you have the money to afford the best, then the LED TV will most likely be your choice.
