Question

LCD is better than LED why ?

Answer 1

Hey,
Ur answer is here,

The LCD TVs you think of now no longer exist. Here’s why: Backlighting. Older LCD TVs used cold cathode fluorescent lamps (CCFLs) to provide backlighting, whereas LED TV's used an array of smaller, more efficient light emitting diodes (LEDs) to illuminate the screen, which gave them a few advantages. Now, all LCD TVs use LED lights, and are colloquially considered LED TVs. 
Hope it helps you ☺️
