Display technologies can be classified based on working principle, lighting (or lack thereof), pixel layout, and more.

; [[Cathode-ray tube]] (CRT) : CRT screens produce an image using electron tube, which fires electrons at a phosphorous coated screen to light up pixels in order to display images.

; [[Liquid crystal display]] (LCD) : An LCD is a display technology employing the use of [[liquid crystal]]s to form images.

; [[Thin-film-transistor liquid crystal display|Thin-film transistor]] (TFT) : A TFT refers to the thin layer of transistors used with an LCD.

; [[LED-backlit LCD]] : An LCD display which uses [[LED]]s as a [[backlight]]. Prior to the use of LED based backlighting, [[Cold cathode#Lamps|Cold Cathode Fluorescent]] (CCFL) tubes were used. LED displays use an array of LEDs to form an image.

; [[Organic Light Emitting Diode]] (OLED) : Unlike an LED display, an OLED display does not use a backlight.

; [[Electronic paper]] (e-ink) : An e-ink display uses encapsulated pigment to form an image resembling printed paper, commonly used in [[e-book readers]].
