Difference Between LED and QLED

Difference between Led and Qled

There is a lot of confusion about the difference between LED and QLED TVs. LED TVs use light-emitting diodes to create pictures on the screen. QLED TVs use quantum dots to create pictures on the screen.  This makes them perfect for creating displays because they can produce very accurate colors. LEDs are good at creating contrast and black, while quantum dots are great at reproducing colors accurately.

What is LED?

A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. The output from an LED can range from very dim to extremely bright, depending on the materials used and the design of the device. LEDs are used in a wide variety of applications, including indicator lights on electronic devices, automobile brake lights, and streetlights. They are also used in some types of optical fiber and in video displays such as televisions and computer monitors.

The first LEDs were made using a crystal of silicon carbide (SiC), which emitted red or yellow light. By varying, the type of semiconductor material and the impurities that are added to it during manufacture, other colors of light can be produced. Today, LEDs are made from a variety of different materials, including gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). The output color from an LED depends on the wavelength of the light that is emitted, which is determined by the bandgap energy of the semiconductor material.

What is QLED?

QLED is a type of display technology that uses quantum dots to produce more accurate colors and brighter images than traditional LCD screens. QLED panels are also thinner and more energy-efficient than LCDs, making them well-suited for use in mobile devices such as smartphones and tablets. While QLED screens have been available for several years, they have only recently begun to gain mainstream popularity due to advancements in the manufacturing process that have significantly reduced costs. QLED technology is now considered to be one of the leading contenders in the next generation of display technologies, and it is expected to continue to gain market share in the coming years.

Difference Between LED and QLED

When it comes to choosing a new television, there are a lot of important considerations. One of the most important is the type of display technology used. Two of the most popular options on the market today are LED and QLED. But what’s the difference between these two technologies? And which one is right for you?

  • LED stands for light-emitting diode. This type of display uses an array of tiny LEDs to create the image on the screen. LEDs are very efficient, using less power than other types of displays.
  • They also have excellent color reproduction, making them a great choice for movies and TV shows. One downside of LED displays is that they can suffer from screen-door effect, where the individual pixels are visible.
  • QLED stands for quantum dot LED. This type of display uses nanocrystals to create images on the screen. QLEDs are even more efficient than regular LEDs, and they offer superb color reproduction.

They also don’t suffer from screen-door effect, making them ideal for gaming and other activities where image quality is paramount. The only downside of QLEDs is that they’re currently more expensive than LEDs.


LED TVs are a great choice for your next television. They offer superior picture quality, longer life spans, and lower power consumption when compared to other types of televisions on the market. If you’re looking for a top-of-the-line TV with all the bells and whistles, then you should consider investing in a QLED TV.
