“LCD” stands for “liquid crystal display,” so some argue it is redundant to write “LCD display” and argue you should use just “LCD” or “LCD screen” instead. But some in the industry argue that “LCD display” is the generic term for the category which comprises both LCD screens and LCD projectors. However, if you want to avoid the redundancy in wording you can still refer more precisely to your laptop or TV as having an LCD screen.
Many people confuse this abbreviation with “LED,” which stands for “light-emitting diode”—a much earlier technology. You will often see explanations even in technical contexts in which “LCD” is incorrectly defined as “liquid crystal diode.”
