Samsung Electronics and Samsung Display are reportedly ready to deliver the first QD-OLED TVs in 2022. Production has reportedly started.

In 2019, Korean media reported that Samsung Display had begun restructuring its LCD panel factories to start producing QD-OLED panels. We were already talking about 2022 for the start of production on this technology with big ambitions on the part of Samsung.

Now, according to Korean media, Samsung Display has started mass production of QD-OLED panels for televisions. The objective of the Korean group? Give Samsung Electronics the opportunity to show its first televisions equipped with this technology at the next edition of CES.

Samsung Display will also supply its QD-OLED technology to other TV manufacturers. Sony, for example, could be both a partner of LG Display, but also of Samsung Display for its next OLED television models.

What is QD-OLED?

As a reminder, this QD-OLED (Quantum Dot-OLED) technology is developed by Samsung, it uses blue organic diodes (OLED), the difference with LG comes from the presence of quantum dots (Quantum Dot).

These QD-OOLED TVs should therefore benefit from the strengths of OLED. Each pixel generates its own light, so the contrast is theoretically infinite. We will also have the other advantages, such as wide viewing angles and instantaneous response time. However, unlike LG's OLED, maximum brightness and color space coverage would be better thanks to quantum dots. In other words: Samsung has replaced the RGB filter with a matrix of nanocrystals, or quantum dots.

Samsung has designed its panel to lower the cost of production: with 13 layers against 22 layers for an OLED panel from LG Display, this limits the quantity of materials required. We can therefore imagine that in a few years, this design would lower the price of OLED televisions.

As a reminder, the main advantage of white OLED panels (W-OLED) manufactured by LG Display compared to conventional RGB OLEDs is that they do not suffer from premature degradation of the blue sub-pixel. W-OLED technology requires placing, above the matrix of organic diodes, an RGB color filter which allows the reproduction of the three basic colors. This filter absorbs light which significantly reduces the brightness capability of W-OLED screens compared to more conventional OLED. In addition, it also impacts the ability to reproduce colors.

Note, however, that LG Display's OLED screens have matured a lot. The third generation matrices, which can currently be found on the G1 model for example, offer very good brightness and color reproduction capabilities.

You will therefore have understood that the QD-OLED technology on which Samsung is working aims to solve the two handicaps of LG's W-OLED, while trying to maintain the advantages of OLED.

The Micro LED in ambush

As a reminder, the other alternative currently under development, and already on the market, is the Micro LED. This technology is already available, but on very large televisions which are currently sold at very high prices.

With QD-OLED and Micro LED, consumers will therefore have more choice, with better quality panels and prices will also drop. However, we will have to wait a few more years. In the meantime, LG will release smaller and larger OLED TVs to meet all needs.

They carry the references of 99MS1A and 110MS1A and they are the very first Micro LED televisions finally marketed by the manufacturer Samsung. These are 99-inch and 110-inch models respectively, producing a…Read more
