What is QLED
QLED, or Quantum Light-Emitting Diode, in simpler terms, elevates the standard LED TV experience by leveraging minuscule quantum dots to intensify its color rendition.
Diving into the essence of how quantum dots function, one can look at the standard LED TV’s light source – typically labeled as “white” LEDs. However, these often lean towards the blue, red, or green spectrum regions. This spectrum bias hampers the color filter’s ability to reproduce true colors with fidelity. Enter QLED. Its illumination originates from blue LEDs with strategically layered red and green quantum dots. The meticulous amalgamation of these three results in an almost impeccable, full-spectrum white light. This refined light source empowers the TV’s color filter to craft a rich and authentic color spectrum for viewers.
Sony pioneered the QLED technology in 2013, heralding a new era in TV clarity. Not long after, Samsung embraced this tech, offering QLED TVs and forging licensing ties with various manufacturers. This collaboration birthed QLED offerings from brands like Vizio, Hisense, TCL, and numerous niche brands. Moreover, e-commerce titan Amazon and streaming leader Roku have ventured into the QLED realm with their newest television series.
QLED – A Parallel to LED TVs
Despite the advanced color enhancements through quantum dots, QLED TVs illuminate scenes akin to their LED counterparts. They employ a backlight array comprising numerous LEDs, positioned behind an LCD panel. This backlight permeates the LCD layer, molding the light into the vivid visuals gracing the screen. These LEDs bestow the “LED” designation upon both LED and QLED TVs.
Delving deeper, the LCD screen operates like a massive ensemble of micro-shutters. These minute shutters rapidly toggle between open and closed states, synchronizing with color filters to shape the final image. While ingenious, the design requires LED backlights to dim in tandem with the shutters blocking residual light to accurately depict on-screen blacks. Its effectiveness in this regard is debatable, a topic we will further examine.
What is OLED
OLED, breaking down the abbreviation, stands for Organic Light-Emitting Diode. Contrary to initial assumptions, the term “Light-Emitting Diode” doesn’t imply a connection to the traditional LED backlighting. Rather, it emphasizes that each minuscule pixel on an OLED screen is its own LED light source – impressively slim, capable of emitting both light and color. This uniqueness means that OLED screens illuminate without relying on a separate backlight, thanks to their self-illuminating, or as industry aficionados say, ’emissive’ nature.
The hallmark of OLED TVs? Exceptional black levels. Unlike their QLED or LED counterparts, which require manipulating backlights to achieve dark scenes, OLED TVs simply deactivate the necessary pixels. With the pixel switched off, it emanates zero light and color, rendering it pitch-black – identical to a powered-down TV state.
In the realm of traditional OLED TV panel manufacturing, LG Display emerges as the sole leader. These panels find their way into TVs manufactured by its affiliate, LG Electronics, which crafts some of the industry’s elite televisions. But LG Display’s clientele doesn’t end there. Renowned brands like Sony, Vizio, Philips, and Panasonic also source OLED panels, bringing diversity in the OLED TV market. And while these panels might bear similarities, the distinct image processing algorithms employed by brands like Sony and LG ensure viewers experience subtle differences in image quality.
Samsung, a giant in display technology, has recently ventured into this domain with its distinct QD-OLED tech. While sharing similarities with traditional OLED, Samsung’s iteration has its nuances, especially its approach to the “self-illuminating LEDs.” A deeper dive into how Samsung adapts OLED tech is warranted.
QLED Vs OLED
When you size up QLED against OLED, QLED might seem to have the upper hand: superior brightness, longevity, a more attractive price point, and zero concerns about burn-in. However, OLED brings its own set of aces – unparalleled viewing angles, profound black depths, energy efficiency, a gamer’s dream performance, and potentially safeguarding your sound sleep. While both are formidable contenders in the TV realm, the choice is inevitably subjective. QLED emerges as the jack of all trades, but OLED shines brighter in controlled lighting conditions.
Diving into a TV purchase is no light matter, especially with the investment involved. Let’s break down the QLED vs. OLED debate based on the vital performance yardsticks: brightness, contrast, viewing dynamics, and other pivotal factors.
Black Levels and Contrasts
Contrast showcases the variance between the darkest and brightest parts of an image. A TV that can achieve pitch-black dark portions doesn’t necessarily need dazzling brightness for an impressive contrast ratio. Here’s where OLED TV steals the limelight – its adeptness to turn absolutely dark when necessary.
Taking a closer look at QLED, the scenario differs. These TVs grapple with the challenge of dimming their LED backlights, aiming to obstruct residual light. Achieving this perfection is a tough nut to crack, often resulting in a phenomenon termed “light bleed.” Picture this: an adrenaline-packed movie scene where protagonists navigate a nocturnal parking space. If you discern a faint illumination in segments meant to be abyssal dark or in the cinematic black bars framing the visual, that’s the bleed in action.
Current trends hint at QLED manufacturers turning to mini-LED backlights as a solution. While it holds promise, declaring it an “OLED defeater” is premature.
With an OLED’s unique trait – its pixel remains pitch-dark without power – it steals the crown in this category. In this QLED Vs OLED battle, OLED really shines.
Winner: OLED
Brightness
Enter the world of QLEDs, and brightness is one of the most striking features. Take, for instance, Samsung’s majestic 98-inch QN100B series, a marvel capable of producing an eye-popping 5,000 nits. One of the leading reasons QLEDs pack such a punch in this realm? Their reliance on separate backlights. Unlike OLEDs that depend on each pixel for illumination, QLEDs sport LED backlights that can achieve stunning brightness, ensuring that even in the sunniest rooms, your viewing remains unhindered.
Contrastingly, OLED panels have some catching up to do in the sheer brightness game. With their design rooted in individual light-emitting pixels, the luminance they offer isn’t as robust as QLEDs. Now, in a dimly lit space, this isn’t necessarily detrimental. In fact, the reduced brightness of OLEDs can be an asset here, offering rich contrasts without blinding the viewer. This approach not only ensures a comfortable viewing experience but is also kinder on your electricity consumption. However, place them in a room awash with sunlight or amidst glaring lights, and QLEDs stand out distinctly, particularly when you’re engrossed in HDR content.
Sure, over time, OLED panels have evolved, reaching impressive brightness levels to compete decently in well-lit environments. Yet, when pitted against the peak brightness of QLEDs, they still fall a tad short.
With the unveiling of Samsung Display’s QD-OLED, many anticipated a leap in OLED brightness. Intriguingly though, LG Display, with its advancements in conventional OLED tech, has kept pace. When juxtaposing the latest from LG’s OLED lineup against Samsung’s QD-OLED, the brightness levels are virtually neck-and-neck. For a deep dive into this, our comparative review of the LG G3 and Samsung S95C spills all the beans. In this QLED Vs OLED battle, QLED is the winner.
Winner: QLED
Color
For the longest time, OLED was the undisputed monarch when it came to delivering colors that left viewers awestruck. Their unparalleled capability to reproduce deep, vivid hues made them the darling of enthusiasts and casual viewers alike.
Enter the QLEDs, backed by the power of quantum dots. Samsung, a dominant player in the QLED arena, posits that these TVs, with their quantum dot prowess, have now not only caught up but are potentially redefining benchmarks for color accuracy, brightness, and volume. The promise? An expansive spectrum of well-saturated colors, even at blinding brightness levels.
But here’s the million-dollar question: Does this uptick in saturation at elevated brightness levels translate to a discernibly better viewing experience in regular scenarios? While it’s evident that QLEDs, with their quantum dot magic, bring splendid colors to the table, there hasn’t been enough convincing proof to say they’ve conclusively outshone OLEDs in real-world viewing situations.
Response Time, Input Lag, and Refresh Rate
Response Time
Let’s kick off with response time. Think of it as the speed at which a pixel transitions between states. A snappier response time translates to sharper visuals, especially when there’s rapid on-screen movement. While our eyes might have a limit to discerning super-fast transitions, it’s undeniable from industry benchmarks that OLEDs are in a league of their own. Standard QLED TVs have a decent response time ranging from 2 to 8 milliseconds. Impressive? Wait till you digest this: OLEDs deliver a staggering 0.1-millisecond response time. It’s clear who the undisputed speedster is.
Input Lag
Let’s pivot to input lag. It’s the delay between you, say, smashing a button on your gaming joystick, and witnessing that move’s aftermath on your screen. It’s crucial for gaming aficionados but doesn’t ruffle feathers in routine viewing. The input lag isn’t so much a TV tech showdown between QLED and OLED as it’s about the TV’s internal image processing. The good news? Both QLED and OLED can boast low input lag, especially when you disable extraneous video processing or engage the TV’s Game Mode.
Refresh Rate and Frame Rate
Lastly, there’s the refresh rate, denoting how often your TV refreshes its displayed content every second. Its cousin, the frame rate, is about the frequency at which content (like TV shows or video games) sends fresh data to the TV. They’re a duo, and for the best visuals, they need to be in sync. Games, especially on high-end consoles or PCs, might tweak their frame rates. To handle such fluctuations, TVs need the VRR (Variable Refresh Rate) feature. Once a unique selling point of OLEDs, as of 2023, top-tier QLED TVs have embraced VRR as well.
Though QLED has made leaps, OLED’s unparalleled response time positions it at the apex. Even if most folks might overlook the nuances, OLED indisputably steals the crown.
Winner: OLED
Viewing Angle Showdown
When you’re positioned right in front of a QLED TV, you’re treated to an optimal display. However, as you drift sideways or adjust your vertical position, there’s an evident decline in brightness, color fidelity, and contrast. This off-angle decline varies across models, but one thing’s for sure: it’s consistently noticeable. Despite commendable strides by manufacturers to tackle this limitation, it’s a thorn in QLED’s side.
Switch gears to OLED, and the narrative changes dramatically. OLED panels promise uncompromised clarity and luminosity even at steep viewing angles, boasting up to a whopping 84 degrees without a hitch. The latest OLED advancements, utilizing the microlens array (MLA) tech, push this envelope further, extending the viewability to an impressive 160 degrees.
In fairness, QLED hasn’t remained stagnant. Some models have incorporated anti-reflective coatings to enhance off-center viewing. But even with these advancements, OLED continues to overshadow its competitor in terms of viewing angles.
For those organizing cozy movie nights with family or hosting large gatherings, if ensuring every corner of the room gets an unspoiled viewing experience is on your agenda, OLED is the clear champion.
