What is QD OLED TECHNOLOGY? | Samsung QD OLED is coming|QD OLED will be available in 2021
Here is the most interestng and exiting news for all the tv
display fans.
Recently Samsung has developed a new technology QD OLED
display technology in their R&D
department in 2019. For this QD OLED technology Samsung display invested US$
10.9billion (INR 8,27,37,43,10,000) .
SO WHAT IS QD OLED TECHNOLOGY?
QD OLED refers to Quantum DOT LED, and it is the hybrid
technology of OLED AND QLED.
Quantum dots (QDs) emit light via a process known as radiative recombination. When an electron in the valence energy band within the QD absorbs a photon and moves to the conduction band, it leaves behind an electron vacancy, or hole. The excited electron and hole then recombine, releasing a photon.

WHAT ARE THE FEATURES OF QD LED COMPARITIVE TO THE OTHER LED
TECHNOLOGY?
BASICALLY LCD,LED,QLED TECHNLOGY produces White color to the
panel but the new QD LED TECHNOLOGY produces blue colour for better contrast
and to produce vivid colors. However OLED does’nt have any backlight. For QD-OLED Samsung is using blue OLED as the light emitting
source, with red and green quantum dots acting as conversion layers for the red
and green subpixels, respectively, while the blue subpixel lets light pass
unhindered. One challenge with this design is that blue OLED has the shortest
lifespan of the three primary colors. LG Display's OLED panel, which is used in
all OLED TVs available on the consumer market, is often described as 'white
OLED', or WOLED, with color filters.
QD-OLED displays also offer other advantages over OLED
screens, including a wider color gamut and improved brightness. Since the
technology mixes OLED with quantum dots, the OLED within the panel will only
emit one color, helping reduce production costs significantly. The
next-generation QD-OLED displays will also be less susceptible to burn-in than
current-gen OLED displays.
SAMSUNG DISPLAY
ANNOUNCES ITS $10.8 BILLION INVESTMENT IN QD-OLED PRODUCTION
Samsung Display formally announced its decision to invest
₩13.1 trillion (around $10.85 billion USD) in QD-OLED TV R&D and
production lines. The investment plan will span 6 years (2019-2025) and the
first step will be to convert an LCD production line in SDC's L8 fab in
Tangjong, Korea to QD-OLED production.The Tangjong line will be converted from
125k monthly substrates of LCD production to 30k monthly QD-OLED substrates,
and mass production will begin in Q1 2021. In the long run SDC plans to convert
all its 8-Gen LCD lines (360,000 monthly substrates) to QD-OLED production
(which will yield around 100,000 monthly QD-OLED substrates).
According to Yonhap, the massive investment will be
officially announced in October. However, a timeframe for the upgrades is not yet
known. The LCD market for larger screens is facing difficulty due to
strong competition from Chinese vendors, backed by state subsidies, who are
able to produce similar displays for a lower price tag. The US-China
trade war is also likely causing strain, with uncertainty and the imposition of
tariffs. LCDs were once a profitable business for companies such as Samsung and
LG, but both companies are moving towards more expensive products, including
OLED and QD in a bid to keep their dominant positions in the display
market.
WHAT IS THE PRICE?
As per the informatition the new QD OLED technology price
quite similar to the price range of QLED technology only .now, this is the big
advantage for us with the less price we can get the best experience of the tv.
The revolutionary potential of QD-OLED notwithstanding, regular QLED panels are unlikely to retire any time soon. In fact, the recent strides made not only by Samsung but also TCL, Hisense, and Vizio in producing affordable, high-quality QLED panels foreshadow a rearrangement of the TV market over the coming decade. Current QLED technology could continue to drop in price to the point of eventually replacing traditional LED TV’s in the budget category, while QD-OLED may go on to become Samsung’s new high-end contender

WHEN THIS TECHNOLOGY COMES TO THE MARKET?
Recently Samsung scheduled to introduce the new QD OLED
TECHNOLOGY but due to some or the other reason it will be resheduled.
On the other side TCL had already showcased the all new TECHNOLOGY recently.
In March 2019 it was unveiled that China-based display maker
TCL is developing a new hybrid display technology that uses a blue OLED emitter
coupled with red and green QD emitters. All three emitter materials will be
combined and printed using ink-jet printing technology. TCL calls this
technology H-QLED and this could prove to be the technology of choice
for TCL's future high-end emissive TV displays.
QD-OLED ON
TRACK TO LAUNCH IN 2021
The OLED Association asked about recent reports in Korean
media saying that the QD-OLED project has been delayed. Samsung Display denied
the reports saying that the project is on schedule.
Inside
the suite Samsung Display also exhibited other prototypes and advancements,
including new materiales for OLED that can reduce power consumption by 10-15%
as well as "a truly foldable display based PC due in 2021". A
31.5-inch QD-OLED prototype was reportedly also shownHope all you got the idea about QD OLED TECHNOLOGY .In case of any other doubts please leave in the comment section.If u liked the blog please feel free to share
