Most people don’t know the difference between quantum dots and quantum mechanics. As it relates to TV’s, it can make a lot of difference.
Unfortunately, people in the market to purchase a new TV are inundated with a variety of acronyms to define the performance of the TV.
LED, OLED, UHD, QLED…what do they all mean?
Which type of TV is ‘best’?
Like many things, the answer is; it depends. There are a number of variables involved with new TVs.
Back to the acronyms, LED stands for ‘Light Emitting Diode’, OLED stands for ‘Organic’ LED (a different substrate material) and QLED stands for ‘Quantum Dot’ LED.
While the acronyms all sound the same, the technological differences are miles apart.
LED and QLED TV’s both rely on backlighting to generate the colours you see on the screen. Quantum dots absorb the backlighting and transmit a corresponding colour. As a result, they are said to transmit light.
OLEDs, on the other hand, generate their colour directly from electrical impulses to each of the diodes. The diodes receive these impulses and emit their corresponding light. This technology is referred to as an ‘emission’.
For price-conscious consumers, LEDs make the most sense. They are the least expensive TV technology on the market today. Many people consider price the most important factor in their buying decisions.
However, OLED technology has advanced rapidly and the price point is coming down to the point of being competitive with current LED/QLED technology.
Emitted Light vs Transmitted Light
The difference between emitted light vs transmitted light gives OLEDs a CLEAR advantage when it comes to the refresh rate, or for watching sports.
Because this impulse and corresponding emission happens almost instantly, OLEDs refresh faster than both OLEDs and LEDs. If you’re a sports fan, an OLED is a way to go.
One area where LED/QLED model TV’s are clearly superior to OLEDs is picture brightness.
Since OLEDs rely on electrical impulses, the diode is either ON or OFF. This produces excellent black and individual colours for OLED pictures. LEDs which rely on a backlit screen were originally brighter.
Technological advances have closed this gap. OLED models are just as bright as any LED/QLED screen now.
While each of these TV technologies has benefits and drawbacks, no one technology is superior in all areas.
It pays to consider the more important variables when making a new TV purchase. The most common is the price. If the price is your chief concern, then go with a good LED TV.
LEDs offer the best bang for your buck. If you can afford a little more, an OLED is a clear choice over the LED or the newer QLED.
Perhaps in the coming years, the emission technology of QLEDs will help it compete with a comparable OLED TV, but for now, OLED is the way to go.
