The history of TV technology is long and complicated, but let’s start with the basics.
OLED (Organic Light Emitting Diode) was first developed in 1987, and OLED TVs hit the market in 2008.
But what is OLED? How does it work? And what about QLED? How does it work? And how do both compare? We will look at that in this article.
What is OLED?
You may have heard of OLED before and thought it was just a display technology, but it’s more than that. OLED stands for organic light-emitting diode, and this alternative to LCD is a flat panel display technology that can be made thinner and lighter than LCD.
OLEDs are made up of individual light-emitting diodes that create a picture on your screen when electricity passes through them. This process is called electroluminescence because electrons send out photons as they move from one energy level to another. The more current you inject into an OLED diode, the brighter it will be; injecting less current will result in less illumination from that pixel. So far, so good! It sounds like we’ve got something here.
How does it work?
OLED is short for Organic Light Emitting Diode. It’s a type of display that uses thin organic light-emitting diodes to produce light within the screen itself, instead of using a backlight like regular LCDs (like those found in televisions and computer monitors).
OLEDs are composed of two layers: an emissive layer and a cathode layer. The emissive layer is made up of organic materials that emit light when voltage is applied to them; this is what gives OLED screens their vibrant colors and deep blacks. The cathode layer serves as an electrical conductor between the positive side of your device’s power supply and your OLED display’s pixels—it also helps boost efficiency by sending current through it instead of having it pass through both layers separately as happens with other types of displays like LCDs
Is OLED better than LED?
OLED is better than LED, especially if you’re concerned about the environmental impact or want a display that will last longer. OLED displays are more energy-efficient and use less power. They also boast better contrast ratios and color reproduction, which means deeper blacks and more vibrant colors.
OLED screens can be made thinner than LED displays, making them ideal for use on smartphones or tablets where space is at a premium. Finally, OLED panels are more durable—they don’t have backlighting like LCDs do so they aren’t prone to burn-in like an old CRT television set might have been when you first got it in your home as a kid (I’m looking at you Windows 98).
What is QLED?
QLED is a type of LED TV, which stands for Quantum Dot Light Emitting Diode. It is a combination of LED and Quantum Dot technology. This new technology has been introduced to the market recently and it’s becoming more popular because of its brighter color tones and a better viewing experience.
How does QLED work?
While OLED displays create light by themselves, QLED panels use a technique called quantum dot to amplify the light produced by LED backlights.
Quantum dots are tiny semiconductors that emit specific colors of light based on their size. They’re often used as color filters in TVs, but Samsung is using them to enhance the quality of its display panels as well.
The benefit of this setup is that it allows for deeper blacks and brighter whites (as well as more accurate colors), which makes for a better picture overall.
OLED vs QLED
The OLED display technology is a big step forward in terms of picture quality. You get deep blacks and vibrant colors that are simply unmatched by any other type of TV. This is especially important as we move into 4K territory, where OLED helps deliver the best images possible and make your viewing experience even better than it was before. But how does QLED compare in each category? Let’s dive in.
OLED vs QLED; Backlight
Unlike QLED, OLED TVs do not require backlights to produce light because they use self-emitting pixels that create their own light (and color). This means that an OLED TV can be very thin and lightweight – which makes it easier to mount on your wall or stand.
OLED vs QLED; Power efficiency
OLEDs also consume less power than a QLED display would need to produce the same amount of light and color output from its pixels (in other words: it’s more energy efficient).
This is because when it comes to efficiency (the amount of light produced compared to the energy consumed), OLEDs can produce brighter images at lower power levels. And since OLEDs do not require their own backlight behind the screen, which consumes electricity even when displaying black pixels, they tend to use less power overall than other more traditional display technologies —although most manufacturers have managed to make improvements in recent years thanks to advancements in technology as well as smarter ways of designing their panels.
OLED vs QLED; Viewing angles
OLED takes the lead when it comes to viewing angles. While most people think about viewing angles first when deciding what kind of TV they want, this metric becomes especially important if you have large groups watching together; seeing how far off center someone’s head needs to be before things start looking washed out will help determine whether a display would suffice, but here, OLED takes the cake!
OLED vs QLED; Affordability
If you’re looking for an OLED TV, there’s a good chance it will be more expensive than its QLED counterpart. This is because OLED uses a different method of generating light than the standard QLEDs used by most TVs and requires special materials that are more expensive to produce.
OLED vs QLED; Brightness
OLED televisions don’t get as bright as QLED televisions either: if you want your picture as bright as possible—even during daytime viewing—you should go with a QLED model instead; otherwise, you might find yourself squinting at your screen whenever someone turns on some overhead lights or opens up blinds in front of them!
OLED vs QLED; Lifespan
The lifespan of an OLED display is slightly shorter than that of a QLED display due to differences in their construction and performance characteristics—but it’s difficult to say exactly how much shorter until more data emerges from real-world use tests (which have yet to begin).
QLED vs OLED: which is better?
You have learned a lot about OLED and QLED, the two big contenders in the TV display space. But which technology is better and why should you care?
The answer to this question is complicated because the two technologies are so different. OLED and QLED offer different things that make them better for different people.
If you want a TV with the best picture quality, go for OLED — but if you want a TV that’s going to be more accurate in terms of color and display more vibrant colors, choose QLED instead.
If you’re someone who cares about brightness levels as well as contrast ratios, though, QLED may be your go-to choice — especially when it comes to HDR content like gaming or movies.
And if you’re someone who wants a more immersive viewing experience than what an LCD screen can provide (or if you just want something that looks really cool), OLED might be better suited for your needs than its QLED counterpart.
While there are other differences between them (including color accuracy), they both produce better pictures than traditional LED panels by using less power and more pixels per inch (PPI).
The main difference is that OLED emits its light while QLED uses a blue LED backlight that filters through red, green, and blue filters to create different colors based on the individual LED’s intensity.
Which one is a preferred choice for the future?
OLED is a highly preferred choice given the fact that OLED screens are more energy efficient, flexible, durable, and eco-friendly.
The OLED screen is also thinner and lighter than QLED screens. Therefore, it can be used in more applications, such as mobile devices or wearables, where space is limited.
OLED is also better for gaming, has a wider viewing angle, has deeper black levels, uses less electricity, and may be better for your health.
QLED on the other hand offers more brightness, a longer lifespan, larger screens, lower prices, and less risk of burn-in.
Companies leading in TV technology
While Samsung is the leading innovator in this space, it’s worth noting that LG and Sony are well-established OLED TVs manufacturers. Vizio, Panasonic, Toshiba, Sharp, and Hisense have also been making strides in this area — they’re all names you should know if you’re looking for an OLED TV.
Samsung has been kicking things up by releasing its QLED technology on its high-end and mid-range TVs. This year we expect to see even more companies join the fray as they try to compete with the biggest players on both sides of the spectrum.
Companies like Philips (which makes Philips), TCL (which makes TCL), and Haier (which isn’t familiar to many Americans but is extremely popular in China) have announced plans to release new lines of OLED or QLED televisions later this year or early next year aimed at delivering excellent picture quality for less than what you’d pay for something from Samsung or LG.
