How Does QLED Technology Work?
QLED technology, which stands for Quantum dot Light Emitting Diode, is a cutting-edge display technology that delivers stunning picture quality and vivid colors. How does QLED work its magic? Let’s dive into the technology behind it.
At the heart of QLED TVs are quantum dots, tiny semiconductor particles that emit light when activated. These quantum dots are made up of different materials, such as cadmium, selenium, or indium phosphide, and their size determines the color they emit.
When a QLED TV is turned on, a backlight illuminates the quantum dots, causing them to emit specific colors. This backlight can be composed of either white LEDs or blue LEDs coated with a yellow phosphor. The emitted light from the quantum dots then passes through a color filter to display the desired colors on the screen.
One of the key advantages of QLED technology is its ability to produce a wide color gamut. The quantum dots used in QLED TVs have a high color purity, which means they can accurately reproduce a wide range of colors. This results in more vibrant and lifelike images, making everything you watch on a QLED TV truly come to life.
In addition to its superior color reproduction, QLED technology also boasts impressive brightness levels. By utilizing high-intensity LEDs as a backlight source, QLED TVs can achieve higher peak brightness compared to other display technologies. This allows for excellent HDR (High Dynamic Range) performance, enhancing the contrast and detail in both bright and dark scenes.
Another notable feature of QLED technology is its ability to enhance viewing angles. With advanced techniques like Quantum Dot Color Filter (QDCF) and Dual-Cell technology, QLED TVs can minimize color shifting and maintain consistent image quality even when viewed from the side. This ensures that everyone in the room can enjoy a stunning visual experience, regardless of their seating position.
To enhance the overall viewing experience, QLED TVs often come equipped with advanced image processing technologies. These technologies, such as AI upscaling and motion smoothing, analyze and enhance the incoming video signals to deliver sharper details, smoother motion, and reduced image noise.

QLED vs. OLED: What’s the Difference?
When it comes to high-end display technologies, two names often stand out: QLED and OLED. While both deliver stunning picture quality, they have fundamental differences that set them apart. Let’s delve into the dissimilarities between QLED and OLED:
Display Technology: QLED stands for Quantum dot Light Emitting Diode, while OLED stands for Organic Light Emitting Diode. The QLED technology utilizes quantum dots and a backlight to produce colors, while OLED technology uses organic compounds that emit light when an electric current is applied.
Picture Quality: Both QLED and OLED TVs offer exceptional picture quality, but they achieve it in different ways. QLED TVs excel in terms of peak brightness and color volume, producing vibrant and vivid images. On the other hand, OLED TVs boast infinite contrast ratios and individually lit pixels, providing deep blacks and precise control over light output.
Viewing Angles: OLED TVs have an advantage in terms of viewing angles. Since each pixel emits its light, OLED displays can maintain consistent colors and contrast even when viewed from extreme angles. In contrast, QLED displays may experience some color shifting and contrast degradation when viewed off-center.
Burn-In Risk: OLED TVs are more susceptible to burn-in, a phenomenon in which static images displayed for extended periods can leave a permanent ghost image on the screen. QLED TVs, being backlit and utilizing quantum dots, do not have the same risk of burn-in, making them a preferred choice for users concerned about this issue.
Lifespan: OLED displays typically have a shorter lifespan compared to QLED displays. The organic compounds used in OLED panels degrade over time, resulting in a gradual decrease in brightness and color accuracy. QLED panels, on the other hand, have a longer lifespan as they do not rely on organic materials.
Pricing: In general, QLED TVs tend to be more budget-friendly than OLED TVs. While OLED technology offers superior contrast and viewing angles, QLED technology provides excellent color reproduction and brightness at a more affordable price point.
Availability: QLED TVs are more widely available from various manufacturers, including Samsung, LG, Sony, and more. On the other hand, OLED panels are currently produced predominantly by LG, limiting the range of OLED TV options.
Ultimately, the choice between QLED and OLED depends on your preferences, budget, and viewing habits. If you prioritize deep blacks and wide viewing angles, OLED might be the way to go. However, if you value vibrant colors and a more affordable price range, QLED could be the perfect fit for you.
What is the QLED Color Volume?
The QLED Color Volume is a unique feature of QLED technology that represents its ability to produce a wide range of colors at various brightness levels. It is a measure of the three-dimensional color space that a display can reproduce, encompassing both the color breadth and color depth.
Traditional displays, such as LCDs, have limitations in reproducing colors accurately and vividly, especially at higher brightness levels. This results in colors appearing washed out or dull when displayed at bright settings. However, QLED technology overcomes this limitation by utilizing quantum dots, which have a high color purity and can emit precise colors across a wide range of brightness levels.
The QLED Color Volume measurement takes into account both the color gamut and the brightness capabilities of QLED displays. It quantifies the range of colors that a QLED TV can reproduce accurately, considering a specific brightness level. In simpler terms, it measures how colorful and vibrant the images on a QLED TV can be, even at different degrees of brightness.
QLED displays can achieve a significantly larger color volume compared to traditional displays, including LCD panels. This means that QLED TVs can produce highly saturated colors with exceptional accuracy, even at high brightness levels. The wider color volume results in more lifelike and immersive visuals, allowing you to enjoy your favorite movies, shows, and games with stunning realism.
The QLED Color Volume is often represented graphically to give viewers a better understanding of the display’s capabilities. The graph typically showcases the color volume in a three-dimensional space, with the horizontal axis representing the color gamut, the vertical axis representing the brightness levels, and the diagonal depth representing the color volume.
Thanks to QLED technology’s superior color reproduction and wide color volume, you can experience images with lush green landscapes, vibrant red sunsets, and stunning blue waters, all coming to life with incredible detail and accuracy.
As the QLED Color Volume continues to improve with advancements in quantum dot technology, viewers can expect even more impressive color accuracy and richness in future QLED displays, further enhancing the visual experience.
