Explanation

LED (Light-Emitting Diode) displays are the thinnest of the listed options. Modern LED displays use LED backlighting behind a thin LCD panel, enabling very slim form factors. CRT (Cathode Ray Tube) monitors are bulky by nature because they require a large vacuum tube. DLP (Digital Light Processing) is a projection technology requiring space for mirrors and a light source. Plasma panels use gas-filled cells between glass layers, making them thicker than LED panels. LED technology enables the slimmest possible displays, which is why nearly all modern thin monitors and TVs use it.
