Both LED and LCD screens use a layer of liquid crystals to help display the image; but, only LED monitors use light-emitting diodes for backlighting; LCD monitors use fluorescent lights behind the liquid crystals. LCD monitors tend to have the same brightness level across the entire screen whereas LED displays can often selectively brightenBoth use this same thing. LED refers to the backlight on the screen. LED really should be labeled LCD with LED backlight. As LED lasts forever and needs less power, this is generally the better deal. Before LED, there was a chance your backlight would burn out, which is bad. TL;DR: LED is better, go for it.
Older LCD TVs used cold cathode fluorescent lamps (CCFLs) to provide lighting, whereas LED LCD TVs use an array of smaller, more efficient light-emitting diodes (LEDs) to illuminate the screen
TFT technology handles how the pixels are displayed on the screen whereas LED refers to how the screen lights up. TFT screens have cold-cathode fluorescent lamp (CCFL) backlighting, LED ones have LED backlighting. LCDs use fluorescent lights while LEDs use those light emitting diodes. The fluorescent lights in an LCD are always behind the screen. You can find the exact difference between LCD vs LED monitor. In the battle of the LCD vs LED Monitor, we will see the differences and will see that which monitor screen is best for us. If you are thinking to buy a new monitor than it is common that you are having a little bit of confusion whether to by LCD or LED monitor. 4K vs. UHD. In simple terms: 4K is a professional production and cinema standard. UHD is a consumer display and broadcast standard. To discover how they became so confused, let's look at the bJLTf5A.
