The frontmost panel facing toward the viewer is LCD, which displays the final image. QLED TVs have several other layers inside, such as a prism and diffuser sheet and a guide panel. That’s not the complete journey of these tiny molecules, though.
These molecules are referred to as quantum dots and, when activated by a light source, emit their own differently colored light. However, it builds on this initial technology by inserting a film of microscopic molecules in front of the panel. The main component of QLED TVs works on an LED panel.

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