What is the meaning of LED TV?
LED TV is a type of LCD television that uses light-emitting diodes (LEDs) to backlight the display instead of the cold cathode fluorescent lights (CCFLs) used in standard LCD televisions. LED TVs are more formally known as LED-backlight LCD television. Edge-lit LED displays can be very thin.
What is led explain?
A light-emitting diode is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons.
How can I tell if my TV is LED or LCD?
The major difference between them is in the display itself. An LED display panel is, in fact, an LCD panel with white light-emitting diodes (LEDs) as backlights instead of CCF backlights. Consequently, LED TVs are thinner than LCD TVs, and the “whites” on the LED TV picture are whiter and brighter.
