QLED OLED QNED TV Buying Guide

What is the QLED OLED QNED TV Buying Guide tutorial about?

In this buying guide, we will see what the differences are between OLED, QLED, QNED, LED, QLED Mini LED TVs, and so on.

What is OLED?

Oled stands for Organic light emitting diode and is a technology found in television screens, phones, laptops, monitors, smart watches and more.

Advantages:

Very good color

Very good contrast

Perfect black

Uniformity

Very good viewing angles

Disadvantages:

They are not that bright compared to QLED

They are more expensive.

They have a tendency to image retention – screen burn-in

What is QLED?

QLED or QNED or ULED or TRILUMINOUS is the old LCD improved by removing the phosphor layer and replacing it with a matrix of nano crystals that display more vivid colors and allow better light transmission.

Advantages:

Very good colors

Very good brightness

Good contrast (if backlight with local dimming is used)

It is a cheaper technology than OLED

Possibility of manufacturing very large screens

Disadvantages:

Black level is not that good if local dimming backlight is not used

Acceptable viewing angles on cheaper TVs

Screen uniformity is not good if local dimming is not used

Optimal diagonal depending on the diagonal and resolution of the content

QLED vs. OLED

Price

OLED is more expensive than QLED

In medium to dark rooms

In less bright spaces, OLED wins, without a doubt

In bright rooms

If there is a lot of light in the room, then a QLED with local dimming will look better

SUSTAINABILITY

QLED has no durability issues. On the other hand, OLED, if displaying static images, logos or stock images for too long, tends to retain the images in the form of shadows that will overlap with future displayed images.

What is Mini LED local dimming?

To come up with a solution to solve the problem with the contract and black level of LCD screens, the solution was found to mount an LED matrix behind the screen, which would be controlled / synchronized with the displayed image.

They are mini LEDs the size of a grain of rice that turn on, off, and change their brightness depending on the image displayed.

This allows for better contrast, deeper blacks and even greater brightness.
