BOE launches a ground-breaking 55-inch UHD AMQLED display

BOE has announced that it has made active-matrix quantum dot light-emitting diode (or AMQLED) technology 4K and TV-sized for the first time. This emerging display standard is based on quantum dots, as is QLED, but does not require a backlight. This may mean it offers more consistent colors and brightness compared to those high-end panel types.

AMQLED is a relatively new rival to technologies such as OLED and QLED. Like the last of those two currently high-end screen materials, it reproduces colors through the medium of quantum dots, which can compete effectively with the former in terms of image quality and consistency. However, in the case of AMQLED, the dots are electroluminescent, which means they can emit light by themselves in response to the current applied to them.

In other words, the resulting AMQLED panel does not require an LCD backlight. This implies the same weight, energy-efficiency and thinness advantages of OLED. In addition, this kind of quantum dot may be capable of a much more even distribution of charges compared to those older standards, which may result in improved color accuracy and uniformity of brightness.

BOE has been involved in the production of AMQLED for several years now, starting out with 5- to 14-inch prototypes showcasing its possible advantages. It is now at a point at which it can introduct its 55-inch 4K/UHD display, the largest and highest-res example based on the technology yet. 

The OEM asserts that it can exceed the NTSC color gamut (getting 119% of this, in fact), and has a 1,000,000:1 contrast ratio. Therefore, BOE touts its new and state-of-the-art panel as ready for upcoming TVs or large-scale monitors, which may be worth watching out for in the future.

I became a professional writer and editor shortly after graduation. My degrees are in biomedical sciences; however, they led to some experience in the biotech area, which convinced me of its potential to revolutionize our health, environment and lives in general. This developed into an all-consuming interest in more aspects of tech over time: I can never write enough on the latest electronics, gadgets and innovations. My other interests include imaging, astronomy, and streaming all the things. Oh, and coffee.
