What Is QLED TV?


In today’s rapidly evolving technology landscape, the world of television has seen tremendous advancements. From the advent of black and white screens to the introduction of color, and from bulky CRT (cathode ray tube) TVs to sleek flat screens, television has come a long way. One such innovation that has taken the market by storm is QLED TV. But what exactly is QLED TV? In this article, we will delve into the world of QLED technology, explore its workings, discuss its advantages, compare it with other TV technologies, look at the top QLED TV brands, consider factors to consider when buying a QLED TV, examine the common features of QLED TVs, and assess the market trends and future prospects of this groundbreaking technology.

Definition of QLED TV

QLED stands for “Quantum Dot Light Emitting Diode.” QLED TV is a type of television that utilizes quantum dots to enhance the display quality. Quantum dots are tiny, nanoscale semiconductor crystals that emit light when illuminated. These quantum dots are embedded in a film layer within the QLED TV screen. When the TV is turned on, the backlight illuminates the quantum dots, resulting in brighter and more vibrant colors on the screen.

How QLED Technology Works

QLED technology works on the principle of quantum dots’ ability to emit light of different colors depending on their size. The quantum dots within the QLED TV screen are engineered to emit red, green, or blue light when energized by the backlight. By combining these three primary colors in varying intensities, the TV can produce a wide range of colors, ensuring a rich and lifelike viewing experience.

The process begins with a white backlight positioned at the back of the television screen. This backlight consists of blue LEDs (light-emitting diodes) which emit a blue light. This blue light passes through a layer containing quantum dots, which absorb some of the blue light and emit red or green light in return. These red and green lights, combined with the remaining blue light from the LEDs, create a vibrant and accurate color palette on the screen.

Advantages of QLED TV

QLED TV offers several advantages over other TV technologies. One of the key advantages is its ability to deliver a wide color gamut. The quantum dot technology used in QLED TVs ensures that the colors on the screen are vivid, accurate, and true to life. This results in a more immersive viewing experience, making movies, TV shows, and games come to life.

Another advantage of QLED TVs is their superior brightness levels. With quantum dots acting as light emitters, QLED TVs can achieve higher peak brightness, allowing for better visibility in brightly lit rooms or during daytime viewing. This makes QLED TVs a great choice for those who prefer a bright and vibrant picture.

Additionally, QLED TVs are known for their excellent HDR (High Dynamic Range) performance. HDR technology enhances the contrast between the brightest whites and the darkest blacks on the screen, resulting in a more detailed and lifelike image. QLED TVs excel in HDR performance, ensuring that every scene is displayed with utmost clarity and visual impact.

Comparison of QLED TV with other TV Technologies

When comparing QLED TV with other TV technologies, it’s essential to consider the differences in display quality, viewing angles, and price range. Let’s compare QLED TV with OLED and LED TVs, two popular alternatives in the market.


OLED (Organic Light Emitting Diode) is another advanced TV technology known for its superior picture quality. Unlike QLED TVs, which use quantum dots, OLED TVs utilize organic compounds that emit light when stimulated electrically. One significant advantage of OLED TVs over QLED TVs is their ability to achieve true blacks, as each pixel is capable of turning off completely, resulting in an infinite contrast ratio. QLED TVs, however, rely on a backlight, which can lead to less profound black levels. However, QLED TVs often offer higher peak brightness and better color accuracy. OLED TVs tend to be more expensive than QLED TVs, making QLED a more budget-friendly option for those seeking high-quality visuals.


LED (Light Emitting Diode) TVs are the most common and traditional type of television found in households worldwide. Unlike QLED and OLED TVs, LED TVs utilize a backlight comprised of LED bulbs to illuminate the screen. LED TVs offer good picture quality and are available at affordable price points. However, they generally fall short in terms of color accuracy and contrast ratio compared to QLED and OLED TVs. QLED TVs, with their quantum dot technology, provide a much wider color gamut, better contrast, and higher peak brightness levels, resulting in a more immersive viewing experience.
