Shopping for a HDTV is not easy these days. After huge an bulky CRTs have become dead, the main three variants of HDTV in the market are LCD TV, Plasma TV and LED TV. Although there is a huge difference between CCFL-backlit LCD, LED-backlit LCD and Plasma technology, the question on which technology is best has remained unanswered.
Early days – plasma technology offered the best picture quality and was the market dominant technology in flatpanel HDTV. But, later after the introduction of thinner and energy-efficient LCDs became less expensive, they started to increase it’s market share. In the recent time, LED-based LCD flat-panel HDTVs have become an ideal choice for it’s lower energy footprint. But, the technology is relatively costly.
|No backlighting (image creating phosphors light up themselves)||Backlight (liquid crystal screen doesn’t light up)||Edgelighting (LEDs at edge)|
|No separate light||cold cathode fluorescent lights (CCFLs) to illuminate the screen||light emitting diodes (LEDs) to illuminate the screen|
|Least expensive (tendency)||Intermediate cost||Costliest|
|Picture quality good||Picture quality good||Excellent picture quality|
|Require more power||medium power||lowest power requirement|
Yes, LED-based LCD is the best flat-panel HDTV technology available. But, it is costly. Let’s compare these three technologies.
