Recently we came across a variety of Television technologies. Some of them are very confusing. For your convenience, here, we are going to compare between OLED vs QLED, the two most demanding TV technologies.
Quite surprisingly, most people aren’t even aware of what type of LED TV they require and how to choose.
What is OLED?
OLED stands for “Organic Light Emitting Diode.”
You may compare OLED panels that are functionally equivalent to the Plasma TVs. OLED is unique since it does not use backlight LEDs to emit light.
Instead, illumination is emitted by billions of separate OLED sub-pixels.
The dots itself are little particles which create an image produce light, that’s why it is named the “emissive” display technology.
Advantages of OLED
- OLED TVs are sleek, light and flexible than normal LCD and LED televisions.
- Unlike LCD and LED displays OLED display does not require glass for supporting.
- As OLED does not require glass, it is much much brighter as the glass absorbs some light.
- OLED does not require backlighting, It produces its own light. As a result it consumes less power.
- OLED TV has 170 degree wider viewing angle.
Disadvantates of OLED
- There is possibility of liquid damage.
- The manufacturing cost of OLED TV is much higher.
What is QLED?
QLED means “Quantum dot Light Emitting Diode.”
Quantum dots are the smallest microscopic molecules that, whenever struck with light, produce illumination of their color.
The QLED panels use colorful quantum dots in a particular type of sheet, and the view from the backlight enters to generate the best picture output.
The illumination then passes through a few different layers within the Television, like a liquid crystal (LCD) film, to produce an image.
Advantages of QLED
- In QLED display you will not face any lag or burn-in.
- You will get bright display even in extreme light conditions.
- It gives bright vibrant colours.
Disadvantates of QLED
- QLED display does not produce its own light. Like LCD display it also gets the light from the backlight passed to it.
Which one is better between OLED vs QLED?
QLED is a renamed modification to current LCD innovation, whereas OLED is an entirely new product.
OLED which terms for Organic Light Emitting Diode utilizes a carbon-based membrane within two conductors that produces its glow as the electrical current is passing across.
QLED is not a new TV panel technology; it’s just a reformed version of the old LED panel.
Indeed, it looks very, very close to OLED, which implies either an attempt to confuse the perceptions of the people purchasing a TV, or a sense of superiority.
OLED vs QLED
Among many differences, below are some the most important differences between OLED vs QLED you must consider.
High Contrast and Black Levels
Among the most critical aspects of picture quality is producing the black level.
And its emissive quality ensures that OLED TVs will entirely switch off inactive pixels for virtually infinite contrast.
The premium QLED panels offer a better full range of local dimming features.
But then also some portion of backlight slips in and destroys the overall picture quality by producing the burnt-out effects.
As a result, we notice faded black tones near to the brighter portions.
The Picture Quality
That is primarily because the most significant changes in QLED image efficiency may not have anything to do with quantum dots.
Alternatively, they are the product of an improved complete variety of local dimming, brighter colors and enhanced viewing angles, which enable them to dramatically outpace QLED TVs that lack such features.
In the meantime, any OLED TV I’ve analyzed does have an outstanding image output, which has won 10/10 video quality.
There has been some variance between other different OLED TVs, but they are not quite as crucial as the variations between the different QLED Television sets.
Brightness of Pictures
The best QLED and LCD TVs will be brighter than just about any OLED type, which again is especially beneficial in more lighted areas even with HDR material embedded.
Throughout my reviews, though, OLED TVs can still provide a lot of light for most of the spaces.
And their outstanding contrast also helps them to offer a sharper overall HDR vision than every QLED or LCD TV I’ve been using.
Color and Viewing Angles
In LCD-screens, certain parts of the panel will look darker than others at the moment. And the backlight pattern could even be visible in specific contents.
But the strongest LCDs often distort, lack clarity, and discolor whenever viewed from positions except for the perfect spot specifically at the front of the display.
OLED TVs feature nearly completely identical displays and preserve accuracy except in the most extreme viewpoints.
Lifespan and Aging
OLED manufacturers claim that their OLED panels will last for 54 years if used for 5 hours a day until they lose their 50 % brightness levels.
And whether it’s accurate continues to be seen, because OLED TVs have been out in the field since 2013.
QLED is much younger, although its backlight origin the LED seems to have a long and established record of success.
For this same justification and for that purpose alone we’re going to give this award to QLED.
OLEDs also come a very long way to get there. When the technology was only in its infancy, the OLED displays reached up to 55 inches.
The LG 88 inch 8K OLED TV is now also available in the market.
That being said, there have been fewer restrictions on QLED screen dimensions. And Samsung’s most significant consumer design presently offers a 98 inches QLED Panel.
Due to on-going worries, the fact would be that the consequence should not be a matter for most people particularly someone with QLED TV because QLED is still not prone to burn-in.
OLED, at the other side, is, and you would have to be bitterly disappointed if this occurs on your Television.
Even though you had a constant picture on that all day every night once and again.
In today’s entertainment culture, it’s easy to waste hours a day watching Television shows with some gaps between each one.
Any Eye related pain or discomfort mainly happens because QLED panels emit heavy blue light from them.
The intensity of blue light from QLED based displays is always more than any other panel technology in the market.
And it is mainly seen while the screen tries to produce shadow effects.
It affects the eyes and the cranky eyes may ultimately lead to sleep deprivation, which also relates to a wide variety of medical issues in the complicated functioning of the human body.
To solve this issue, several OLED manufacturers most prominently LG, are already pursuing Ocular Guard approval for their OLED screens.
So, an OLED TV screen offers much more visibility comfort.
As you are well conscious, OLED modules do not need an extremely-bright backlight technology.
These little backlights use a reasonable amount of electricity, which ensures that OLED TVs are the most power sufficient.
On the other hand, QLED TVs produce more heat in comparison with OLED Televisions.
For quite some time, this segment would have been convincingly dominated by QLED TVs.
However, OLED TVs have fallen in price, and since we’re discussing all-premium here, comparable QLED TV quality is almost the equivalent (or even more, depending on the size).
2020 will become a critical season, especially for the Television industry.
Here, we will see much more OLED Televisions by manufacturers like Vizio and Philips, which will further place additional pressure towards cheaper costs.
Still, at the same time, TCL’s mini-LED QLED TVs might drive throughout the reverse direction, trying to improve the output we should anticipate from cheaper-cost screens.
The Best Response Time Offered
The response time means a fixed time interval a pixel takes to change from its current state to the next state.
The quicker the response time, the sharper the picture, particularly during fast-acting action sequences.
Here, we can say OLED TVs are much quicker, even thousands of times quicker than the QLED TVs.
OLED vs QLED – Final Verdict!
All of the above developments are amazing in their own way. But if we want to pick the best, for the present, it’s OLED.
For great results throughout the area, most viewers would note when viewing Television programs, including videos, it’s the most excellent image quality money can afford.
You can see both the Television Panel technologies offer all screen resolutions, including 4K, and can even stream 8K contents on them without any issues.
Both techniques seem to have a significant intrinsic superiority in the fields of color or video transmission.
Moreover, both OLED and QLED screens are good. However, deciding amongst them is personal.
QLED seems to be the best all-rounder, but OLED shines if you can only monitor the brightness in your house.
Now, it is up to you which you will choose as per your convenience.
