- Full-array LED: This type of display features LEDs arranged across the entire back of the screen, providing more even lighting and better contrast.
- Local dimming LED: This technology allows different areas of the screen to be dimmed or brightened independently, improving contrast and black levels.
What is QLED?
QLED (Quantum Dot Light Emitting Diode) is a newer display technology that’s been gaining traction in recent years. Developed by Samsung, QLED uses tiny crystals to create colors, rather than traditional LEDs. These crystals are incredibly small, measuring between 2-10 nanometers in size, and are able to produce a wider range of colors and more precise control over brightness.
QLED displays are known for their exceptional color accuracy, high contrast ratios, and faster response times compared to traditional LED displays. They’re also less prone to image retention, a common issue with OLED (Organic Light Emitting Diode) displays. QLED displays are typically more expensive than LED displays, but offer superior picture quality and a more immersive viewing experience.
How QLED Displays Work
QLED displays use a different approach to creating images on the screen. Here’s a simplified explanation of how they work:
- The QLED panel consists of a layer of tiny crystals, each emitting a specific color when an electric current is applied.
- The crystals are controlled by an electric current, which determines the brightness and color of each pixel.
- The QLED panel is paired with a backlight, which provides the necessary illumination for the crystals to produce colors.

What are LED and QLED displays?
LED and QLED are both types of display technologies used in modern televisions and monitors. LED stands for Light Emitting Diode, and it refers to a type of display that uses an array of LEDs to produce the images on the screen. QLED, on the other hand, stands for Quantum Dot Light Emitting Diode, and it’s a more advanced technology that uses tiny crystals to create colors and produce the images.
Both LED and QLED displays are considered high-end options, but they have some key differences in terms of picture quality, brightness, and color accuracy. LED displays are more common and widely available, while QLED displays are typically more expensive and found in high-end TVs and monitors.
What is the main difference between LED and QLED displays?
The main difference between LED and QLED displays is the way they produce colors and light. LED displays use a backlight to produce white light, which is then filtered through a layer of color filters to create the images on the screen. QLED displays, on the other hand, use tiny crystals to create colors, which are then lit up by a backlight to produce the images. This results in better color accuracy, higher brightness, and a more vivid picture quality in QLED displays.
QLED displays are also capable of producing true blacks, as the crystals can be turned on and off to create perfect darkness. This is not possible with LED displays, which can sometimes produce a greyish tint when displaying black images.
