With the development of technology, TVS in recent years tend to be high-end and flagship specifications. boe 2023 In addition to the delicate and thin appearance, panel technology has also been improving. When LCD TVS came on the market in the past, we all thought it was very advanced panel technology, but now there are organic light-emitting diodes and QLED panels with different specifications and technologies.

OLED and QLED may seem like just the first letter of the letter, but there are some differences between them:

OLED

Organic light-emitting diodes (OLEDs) have nothing to do with the LCD screens used in TVS. BOE displays They are self-luminous and can glow on their own.

QLED

Quantum dot light-emitting diodes (qds) are a type of LCD screen, so they rely on backlight just like LCD screens.

OLED, QLED stands for

What is OLED?

Organic light-emitting diode (organic light-emitting diode) is an organic light-emitting diode (organic light-emitting diode or organic light-emitting semiconductor).

Organic light-emitting diode (OLED) is a current type self-luminous device, oled manufacturer and the luminous intensity is proportional to the injection current.

Because OLED is easy to make, it has the characteristics of thin, wide viewing Angle, high response, and good clarity, and is also suitable for making screens.

What is a QLED?

QLED (Quantum Dot Light Emitting Diodes), known in Chinese as quantum dot light-emitting diodes, is specifically made of some tiny semiconductor nanocrystals that cannot be seen by the naked eye.

QLED can be said to be a kind of liquid crystal screen, its quantum dot stability is quite high, coupled with mature backlight and liquid crystal panel, so the service life is relatively long.

In addition to this impact, the partial performance of brightness and screen size will also be better and larger than OLED.

QLED and OLED differences

What are OLED and QLED? Do you have a better understanding of these two panel technologies? Perhaps now you will still think that these two specifications are what!

In fact, OLED and QLED can be compared according to five aspects, and it is easier to distinguish the difference between the two.

1. Picture color

Compared with organic light-emitting diodes, QLED color accuracy is higher, even in higher brightness places can display color saturation, for a variety of brightness can display accurate color quality; However, organic light-emitting diodes are not as accurate as QLED in color, but mainly depends on the manufacturer's color technology.

2. Screen black

The so-called black level is that the partition and control system of the screen backlight can be appropriate, in short, when the black screen is presented, the effect of all black can be presented, and this technology has more advantages on OLED.

3. HDR effect

The HDR effect is the difference between the highest and lowest brightness. The HDR effect of OLED can reach very low brightness, while the HDR effect of QLED can reach the highest brightness.

4. Viewing Angle

Even a 50-inch TV may not be able to see clearly in every viewing Angle. The most important thing is to look at the perspective of the panel. Organic light-emitting diodes and Qleds are almost mature in this regard, even at a slanted Angle. You can also see the color of the picture.

5. Appearance size

It's easy to tell the difference between OLED and QLED, you can tell by the size. Oled TVS are limited in size, with current ranges ranging from 55 to 65 or 77 inches, and Qleds cover almost every other size.
