With new HDTV’s and monitors coming out every day, you may find yourself wondering what the difference is between LCD and LED displays. This article will provide a better understanding of the differences between the two displays.
LCD, or liquid crystal display, are the most commonly used panels in televisions, smartphones, tablets, and monitors. The screen is made up of liquid crystal molecules that can take certain patterns to either allow or block light. Fluorescent bulbs are used to light the molecules, as the crystal molecules do not emit any light.
LED, or light-emitting diode, also have liquid crystal molecules but use a different lighting system. Instead of fluorescent bulbs to light the molecules, LED screens have strips of light emitting diodes. There are a few different types of LED displays, each having different ways to turn on the crystal molecules. LED screens can come in edge-lit, full array, or RGB. I will briefly explain each below.
Edge-lit LED screens use light around the display’s edges. The light is directed to patterns on the screen to create an image. Edge-lit LED panels are most common in slim monitors and are much more cost-effective than other LED options. Full array LED screens have a full sheet of light emitted diodes behind the liquid crystal molecules, allowing for a greater range of colors and images on the display. The full array LED displays are more expensive that edge-lit, but offer a better picture quality. Red Green Blue LEDs are either edge lit or full array and use colored light emitting diodes for more precise colors and sharper images. RGB LED displays are the rarest type of panel and are more expensive than other LED setups.
In conclusion, LCD and LED displays are very similar. The main difference is the way the crystal molecules are illuminated. LCD displays are, and will continue to be the prominent panel technology. LED panels are notable as a more cost-effective solution. Unlike LCD panels, the light emitting diodes in LED panels do not need to stay on the whole time. Certain diodes can turn off when not needed, which leads to a more energy efficient display.
Whether you are in the market for a new laptop or an HDTV, having a better understanding of LCD or LED displays will help you make the right choice.
