Super AMOLED display Segment displays ,
9-segment,
14-segment and
16-segment displays Some displays can show only
digits or
alphanumeric characters. They are called
segment displays, because they are composed of several segments that switch on and off to give appearance of desired
glyph. The segments are usually single
LEDs or
liquid crystals. They are mostly used in
digital watches and
pocket calculators. Common types are
seven-segment displays which are used for numerals only, and alphanumeric
fourteen-segment displays and
sixteen-segment displays which can display numerals and Roman alphabet letters.
Other types •
Vacuum fluorescent display •
Electroluminescent (ELD) display •
Plasma (PDP) display • Laser-powered phosphor display
Cathode-ray tubes were also formerly widely used.
Full-area 2-dimensional displays 2-dimensional displays that cover a full area (usually a
rectangle) are also called
video displays, since it is the main modality of presenting
video.
Applications of full-area 2-dimensional displays Full-area 2-dimensional displays are used in, for example: •
Television set •
Computer monitor •
Head-mounted displays,
Heads-up displays and
Virtual reality headsets •
Broadcast reference monitor - Industry/non-common consumer directed hardware/equipment. •
Medical monitors •
Mobile displays (for
mobile devices) •
Smartphone displays (for
smartphones) •
Video walls
