Differences between LED, QLED and OLED

Attention question. What television screen do you think is better? It does not always depend on the price, although in this case it does. That’s why it would not hurt for you to learn, if you have not already done so, to differentiate and appreciate the quality of the product due to the technical characteristics it has.

The key is in the pixels

As for the screens, everything depends on the way in which the pixels or points of color illuminate. It is decisive to assess the quality of the image. And this is precisely where the difference between LEDs, QLEDs and OLEDs lies. We go by parties.

LED screens

LED (Light Emiting Diode) displays use white LEDs that illuminate color pixels from behind. Dark and pure blacks are almost impossible on a screen of this type. The viewing angles vary depending on the model. The quality of the image is good especially if the model has HDR (High Dynamic Range), short for one of the improvements included after the label «Ultra HD Premium.»

QLED screens

QLED (Quantum Dot Light) panels are an evolution of LEDs and Quantum Dot technology or nanocrystals. The difference between the two is that in the latter, the pixels can be activated individually, allowing greater contrast and closer to OLEDs in its great advantage: the purest blacks.

OLED screens

The OLED (Organic Light Emiting Diode) pixels produce their own light which allows to control the brightness pixel by pixel, save layers and get screens of minimum thicknesses. The vision is almost perfect from all angles. They have a greater potential than LED screens to show excellent colors, although sometimes they can cause an unnatural tone. Are very expensive.
