QLED, or quantum dot light-emitting diode (LED), is a display panel used in high-definition TVs (HDTV). The quantum dots or nanocrystal semiconductors in a LED-backlit liquid crystal display (LCD) reduce light losses and produce monochromatic red, green, and blue (RGB) light. As a result, the device’s display is clear and distinct, with better picture quality than traditional LED screens.

Korean TV maker and electronics giant, Samsung, has experimented with electroluminescent displays based on QLED as a variation of LED LCD. QLED offers an alternative to the organic light-emitting diode (OLED)-based ones. Samsung’s competitors, such as LG, Sony, and Vizio, use OLED, a different technology from LCD.

Who introduced QLED first?

Sony first introduced the QLED technology for television in 2013. But in the years that followed, Samsung increasingly edged out the competition by making a sizable investment in QLED research. In 2018, Samsung launched QLED TVs, which helped boost Samsung’s revenue projection in the first quarter of 2018 to 15.6 trillion won (Korean currency) or $13.3 billion.

QLED’s features and benefits

QLEDs as a component of an LCD screen are used to enhance the display’s picture quality. The quantum dots fix the light glare commonly associated with LED-backlit LCD TVs.

The LCD TV has three parts: a white LED backlight, color filters, and a liquid-crystal module (LCM). The three parts work together to provide a better color experience. The LED passes through the color filter and the pixel grid of the LCM, which blends light and color to produce an image.

The right mix and balance of light and RGB subpixels create different hues and shades, enhancing picture quality. QLED provides a clean source of light evenly distributed across the RGB color spectrum. And it is easier to control the output of quantum dots that glow an array of colors, making it possible to balance light and colors with precision.

QLED offers better picture quality for 4K UHD TV or 1080p HD TV with a more accurate color mix and just the right amount of brightness.

How is QLED different from OLED?

While QLED adds quantum dots to the LED, OLED stands for organic light-emitting diode, which functions differently. OLED is a thin and tiny LED light that generates light and color in a single element without needing a backlight. OLED pixels are considered self-emissive in that they produce their own light.

QLED TV for business and home entertainment

A QLED TV panel has a better resolution with 4K at the minimum and 8K at the max. With a full HD screen and superior picture quality, these TVs offer a better, brighter picture quality in the home entertainment setting. A high-resolution screen equally works well in an office setting.
