TV technology has changed incredibly since the first color broadcasts in the mid-1950s. That rudimentary technology had limits that often led to low-resolution images with inaccurate colors. But advances in research meant that manufacturers could produce more brilliant colors with higher levels of detail. This led to the creation of cathode-ray tubes, then to plasma and liquid crystal display TVs.
The next evolution in display technology turned organic light-emitting diode models into popular household items. Due to their higher 4K and 8K resolutions and accurate color reproduction, OLED TVs are great for video games and films. However, quantum dot LED TVs are also an excellent choice.

How QLED works
The main component of QLED TVs works on an LED panel. However, it builds on this initial technology by inserting a film of microscopic molecules in front of the panel. These molecules are referred to as quantum dots and, when activated by a light source, emit their own differently colored light.
That’s not the complete journey of these tiny molecules, though. QLED TVs have several other layers inside, such as a prism and diffuser sheet and a guide panel. The frontmost panel facing toward the viewer is LCD, which displays the final image.
QLED vs. OLED
The two kinds of TV models share the “LED” acronym, but they operate differently from each other. Where QLED is a variation of the transmissive LED LCD technology, OLED is emissive and uses individual OLED subpixels … and no LED back panel. These subpixels are responsible for their own light source, increasing color accuracy, brilliant visuals and overall image quality.
Samsung is perhaps best known for QLED TVs, but several other brands use the same technology under different names.
