Samsung QLED
At the time and without more accurate information, it was difficult to estimate when Samsung’s first QD-OLED TVs will hit stores, but now we have a tangible clue that invites us to conclude that they could arrive sooner than expected. It does not seem an exaggeration to think that in 2021 they will already be in stores. In fact, Samsung Display has acknowledged that by the end of 2020 it will stop manufacturing LCD screens at all its factories in South Korea and China.
A spokesperson for the Korean company acknowledged this to Reuters: Samsung will stop manufacturing LCD screens this year to accelerate the adoption of new technologies in the field of next-generation displays.
The transition described by Samsung reaffirms the commitment to QD-OLED. Quantum dots would be Samsung’s bet in competition with OLED televisions that we already find in stores.
QLED TVs produced by the South Korean company in recent years to compete in the mid-range and luxury also used LCD screens, so Samsung will bet on QD-OLED in the future.
However, there is a compelling reason for Samsung to trust quantum dots, but that does not mean it will abandon LCD technology. Samsung Displey will no longer manufacture this type of display, but Samsung Electronics also has other LCD display providers, including Innolux, HannStar, HKC, New Vision Disolay, TCL, and Japan Display.

At this point, it’s inevitable to wonder how LCD TVs and QD-OLED models will coexist in Samsung’s portfolio when the latter finally hits stores. We can only speculate, but QD-OLED TVs will most likely take the current place of QLED models in the mid-range and deluxe. LCD televisions will continue to compete in the input and midrange ranges, where prices are a deciding factor.
The working principle of Samsung QD-OLED screens will be very similar to OLED screens produced by LG Display and those produced by other major manufacturers such as Philips or Sony. However, if we focus only on the strategy they use to reproduce colors, the first significant difference between the two technologies appears. OLED screens manufactured by LG Display are of the W-OLED type (white OLED), through which the light emitted by each of the panel’s self-emitting cells is white. The problem is that to compose a color image we need three primary RGB colors (red, green and blue), so it is necessary to place an RGB color filter on the organic diode matrix that can reproduce them.
However, Samsung’s proposed changes to W-OLED technology do not stop here. Unlike LG’s OLED displays, which use white pixels, Samsung’s will use blue pixels, so nanocrystals will be responsible for the action in blue light to generate the other two primary colors (red and green). This transformation is possible thanks to a very interesting property of nanocrystals: the structure allows them to change the length of the light wave, so they manage to manipulate the blue color to generate red and green light from it.
Samsung QLED – the future
With the advent of Samsung’s QD-OLED displays, we will be able to see if they will be serious competition for OLED. What we know for sure is that Samsung’s entry into the OLED TV market is good news for us users. Samsung has dominated the global TV market for 14 years, so the arrival of QD-OLED will bring fierce competition to LG Display, which is currently the only manufacturer of large-format OLED displays for televisions.
