Knowledge of LCD LED OLED QLED！(2)
We often see LCD, LED, OLED, QLED, although the difference is only one letter, but the difference is very big! Today, Sally will explain it in detail here for your reference and study.
Let`s study the LED now!
LED
LED (Light-emitting diode) light-emitting diode screens. In fact, the images of these displays are still generated by liquid crystals. Light-emitting diodes are only used as light sources. Technically, they are still LCD Displays, or LED-backlight LCD TVs.
To put it bluntly, LED is a kind of LCD. Some manufacturers deliberately call TV "LED TV", which can basically be regarded as hype, and they want to move closer to OLED and sell it at a high price. Friends, you must see clearly!
Liquid crystal (LCD) TV with LED Screen has the advantages of small size, low power consumption, long life, low cost, high brightness, long viewing angle and high refresh rate. The disadvantage is that the color performance is relatively poor, especially when the LCD Screen is folded where the color deviation is more pronounced.
