Discover the Difference Between OLED and Quantum Dot (QD) Tv

Why OLED is superior to QD

Can you imagine yourself having a HD TV while watching your favorite movie in an 80 inches wide television set that consumes less electrical power? This type of high definition television is now possible with the use of the OLED and QLED televisions.
With the evolution of technology, electronic companies are making innovative designs of televisions that offer amazing display technology, power efficient features, and unmatched color quality.
Due to consumer’s demand, the market is now offering televisions made from QLED and OLED offering great features of LED-based products which is high-power efficient, flexible, and versatile. The development of new television displays and lightning forms made the electronic consumers to be confused on what to buy. This article will help you to fully understand the difference between the OLED and QLED.
The truth is, in terms of performance and quality, OLED display and Quantum Dot (QD) TV manufactures are competing each other. Most electronic companies are boosting their OLED e-products in which according them are the best display technology in the market today.

What is the Quantum Dot (QD)Technology?

Quantum Dot is composed of semiconductor materials which look like a nanocrystal sphere. With the presence of electricity, these nanocrystals emit light by absorbing light. The lightning wavelength varies depending on the dot size.

LCD alone is not capable of emitting its own light. There should be a light source or backlight. A LED backlight utilized the three basic colors-blue, green, and red in order to come up with a white color light. Nowadays, one of the popular LED LCD colors is blue coated with a yellowish phosphor to achieve a white light color and QD LED TV is a more advanced version of this. The manufacturer no longer used the blue LED with yellowish phospor, but instead they use QD particles in creating white color. The QDLED absorbs the emitted blue light then transfer it to red and green to creating the desired white color. This process is known for achieving an accurate LED colors.
What is the organic light-emitting diode (OLED)?

OLED is composed of organic molecules made of thin films that create light with the use of electricity. This type of lightning technology is capable of creating crisper and brighter displays on electronic devices than the traditional liquid crystal displays (LCD) and light emitting diodes (LED).

OLED versus QD

Meanwhile, the Organic Light-emitting Diode (OLED) display is made of organic compound which releases light with the presence of an electric current. The pixel is capable of emitting light on its own. It only means that this type of LED display have no issues regarding backlight leaking. Thus, Organic Light-emitting Diode is different from Quantum Dot Light-emitting Diode in terms of in expressing colors.


QD LED uses LCD-based technology which is slightly difficult to consider as the next generation display. However, OLED is considered as the next generation display which is transparent, flexible and roll-able . It has relatively low processing temperature suited for a plastic substrate when you wish to make a flexible display and because it does not require a backlight as compared to QD, it can be optimized in creating a transparent generation display.


When you say good definition, you are able to consider the important elements such as bezel width, display size, contrast ratio, brightness, response speed, and color gamut.

The OLED TV has 108 % color gamut which is lower than the 125% color gamut of QD. You can easily say that QD is more accurate in terms of color definition. However, in a dark environment with low temperature, the color gamut may not be as great as OLED’s. With 0.001 milliseconds respond time and 10, 0000:1 contrast ratio, say goodbye to blur problems! OLED display is 1,000x faster that LCD TV’s making it more advantageous to use.


OLED TV does not need for a backlight since it can display images when the OLED particles emit its own lights. On the other hand, the QD TV uses tube or film in front of the backlight in expressing colors.


The price of QD TV is more competitive than the cost of LCD and OLED. OLED’s market is quite small though there is a rapid increase on the demand. It is expected that for the next coming years OLED will be more competitive.


OLED TV is more efficient, better-performing, lighter and thinner than any television technology. The OLED technology can be divided into two camps-white OLED and the RGB OLED. Basically, you need three colors, red, green, and blue wherein no other television technology creates color scheme directly like this. This unique LED structure and electroluminescent layer does not require a pixels and backlights making it the best screen technology these days.

Unlike with the synthetic LEDs, OLED make use of carbon-based organic elements that glows by the presence of electric current. The idea is part of the innovative design which aims to reduce the weight and thickness of the TV. The high-definition images will be produced once the light passes through a filter. Many manufactures are using this amazing technology to make an ultimate display and viewing experience in your own home theater.

Do not be confused with the LED TV although LED also stands for “light-emitting diode”. The LED TV use range of LEDs like the traditional LCD TV, but with OLED, there is a self-emit light source for every pixel that offers deepest contrasts and richest colors at an unmatched weight.

Why QD?

QDs are said to be soluble in non-aqueous and aqueous solvents which creates flexible and printable displays. Since QD is inorganic, it offers limitless potentials for lifetime improvement compared to OLED. It has also a much improved saturated green colors.

Though the structure of QLED is quite similar to OLED, you can easily tell the difference between the two by checking its light emitting centers which is made of cadmium selenide nanocrystals or simply called quantum dots. QLEDS are known for having less manufacturing costs and lower power consumption. QLED’s manufacturers claim that QLED TVs are more power efficient than OLEDS with same color purity.
