LCD stands for “Liquid Crystal Display,” which perfectly describes the technology at play. In simplest terms, LCD screens feature a large panel of liquid crystals held between two pieces of glass. When fluorescent backlights shine on the panel, the crystals change shape, color, and opacity to produce the picture on the screen. LED, meanwhile, stands for “Light-Emitting Diode,” which actually describes the backlights rather than the technology itself. That’s right — LED monitors use the LCD method of projection, just backlit with LED lights rather than fluorescents. LED TVs provide sharper contract and better efficiency than LCD models, but brightness is their biggest advantage in outdoor settings. It’s not coincidence that all the outdoor TVs we currently carry are of the LED variety. You should also be aware of OLED (Organic Light-Emitting Diode) and QLED (Quantum Light-Emitting Diode) TVs, both of which are relatively new technologies. OLEDs trade backlighting for pixels that produce their own light and color, resulting in sharp contrast and quick response time. QLEDs rely on quantum-dot nanoparticles that filter color and light to generate gorgeous displays.
