Quantum Dot is a phenomenon that many of
us might be seeing in real life in some of the most common applications, but
not be actually aware of its meaning. So what is it, and how has it positioned
itself in electronics and medical sectors around the globe?
Ever wondered what made LCD screen colors in laptops,
tablets, phones, e-readers, and televisions so vivacious? Would you believe if
you were told that these colors were being emitted by tiny dots, called quantum
dots? Quantum dots first burst onto the technology scene in 2015, and the
appeal, especially in the consumer electronics industry, has only grown since.
One of the most common uses of Quantum Dot displays is in television sets,
where it is referred to as QLED. It can be thought of as a direct competitor
for OLED TVs, where it holds many advantages over the latter. Quantum dots also
find application in other areas such as biology and healthcare. They can be
expected to replace single crystal semiconductors that are currently used in
camera sensors, solar panels and medical imaging tools.
What Exactly are Quantum Dots?
Quantum dots (QDs) are nanocrystals or tiny particles
of a semiconducting material. They are roughly one ten-thousandth the width of
a human hair, thus justifying their name. When supplied with energy, these
quantum dots start glowing. The color of the quantum dot is determined by its
size; so, a smaller one may glow blue, while a larger one may glow red or
orange. Quantum Dot Display is simply a display device using QD with
semiconductor nanocrystals that results in the production of monochromatic red,
blue and green light. Quantum dot displays can replicate up to 93% of the
colors that are visible in the natural world and are highly energy efficient.
QDs, when exposed to suitable light, turn luminous,
generating very pure color. Quantum dot display brightness is 10 to 20 times
more than organic dyes. When grouped together in designated sizes, and combined
with a blue LED light source, they transmit light across the whole bandwidth
which is required for optimal TV viewing. As the semiconductor material
shrivels to quantum-dot level, the ‘light wavelength’ material changes from
insulator to conductor.
Benefits and Applications
Quantum Dot displays are used in biological imaging,
renewable energy, optoelectronics, security, surveillance, and quantum optics.
In biological imaging, they are used for in-vitro and in-vivo imaging to detect
cancer cells. Across optoelectronics, they are used in LEDs for more vivid
color ranges. Quantum particles cells are anticipated to be a renewable source
of energy in the future.
As opposed to conventional LCDs, quantum dot displays
offer much improved color accuracy. Using this technology, LCDs can offer stiff
competition to OLED devices, as they offer comparable color range to the
latter. Also, when viewed under direct light or sunlight, Quantum Dot displays
offer much more brightness than OLED ones, which is a major advantage. QD LED
display devices are incorporated in ultra-flat LCD (liquid crystal display)
panels.

Medical devices, sensors, lasers, photovoltaics,
chips, LED display devices, and LED lighting devices constitute the market
applications. QD displays find ‘imaging’ applications in medical devices,
helping detect cancerous cells. Laser devices are used in biological
cell-tagging. Photovoltaics are employed in power stations, buildings, solar
roadways, transport, and others. Sensors, on the contrary, are adopted for the
detection of biochemical & chemical molecules.
Quantum Dot display technology is one of the most
exciting technologies around. It is no wonder then, that the market is expected
to grow significantly in the coming years. Some of the factors aiding in
the quantum dot display market growth are:
- There
is an increased demand for QD-enhanced LED displays around the globe,
owing to its comparable and in some ways, better performance than OLED
displays, thus leading to market growth.
- Energy
efficiency, production of more vibrant colors, as well as better
brightness are some of the properties that have made quantum dot displays
highly desirable in the market.
- Continuous
improvements in performance of quantum dot displays are being made, with
development of high-resolution displays requiring lower power consumption.
- With
global focus on health and fitness, quantum dot display technology is
finding rapid usage in the healthcare field, especially in wearable
devices.
- Biological
imaging, targeting and detection are some more medical applications where
quantum dots have found promising application, and significant growth can
be expected for this market with regards to usage as an effective
alternative to fluorescent probes in biological imaging.
- Top
manufacturing companies such as Samsung, LG, Sony and TCL are
incorporating the technology in their products, which has accelerated
quantum dot display market growth for these display devices.
However,
with these displays requiring extraction of heavy metals such as cadmium along
with other rare earth minerals, which are available in limited quantities,
there are stringent Government regulations against their use in manufacture of
Quantum Dot display devices, that can hamper future market growth.
