It seems that this edition of the SID Display Week 2022 It has brought us some very interesting surprises. On the one hand, we saw a perfect 3D screen to watch Avatar 2 at home, in addition to the TCL OLED Smart TV that has been manufactured with a process that significantly lowers its price. And now it’s the turn of BOE, which has just introduced the world’s first 55-inch 8K AMQLED display.

As reported by the Chinese manufacturer through a press release, the company has successfully developed the world’s first 55-inch 8K quantum dot active matrix display (AMQLED) using its new electroluminescent quantum dot technology. .

To say that in 2020 they presented the first 55-inch AMQLED screen with 4K resolution, now taking a new leap to show that their technology is increasingly perfected.

In case you did not know BOE, say that it is the largest manufacturer of LCD panels worldwide, a benchmark in the sector and that it has taken advantage of the idyllic setting offered by this screen fair to show its latest developments.

Regarding AMQLED technology, as the manufacturer explains, uses electroluminescent quantum dot technology, combined with oxide TFT conduction and inkjet printing process for all functional layers (except cathode), which made it the true “active self-emitting quantum dot display”. .

When AMQLED and OLED technologies are compared there are numerous similarities, the main difference being the materials used to make the displays. Quantum dots are a type of semiconductor nanocrystals that, due to their size (2~10nm), have a fundamentally different electronic structure than bulk materials, resulting from the quantum confinement effect.

This technology requires a backlight system, but AMQLED does not use a backlight, rather the quantum dots are laminated by current injection to achieve self-emission properties, as well as a wide color gamut and longer panel life.

Inkjet printing is not a new technology, we have already seen it at TCL to manufacture cheaper OLED panels in this edition of SID Display Week, offering the same process that manages to reduce waste materials, significantly reducing production costs. manufacturing.

This company has been working on this AMQLED technology for years as it considers that it can be an alternative to traditional OLED and LCD. BOE launched a series of AMQLED displays, including 5-inch, 14-inch and 55-inch (4K) demos at SID 2022. And now, with their new 8K display, they want to make it clear that they are one of the major players in the field of AMQLED displays. quantum dot displays
