Flatpanel
Flat-panel displays are thin, lightweight display devices that present images on a flat substrate. They are used in televisions, computer monitors, laptops, smartphones, tablets, and signage, and they contrast with older cathode-ray tube displays in form factor and power consumption.
The major flat-panel technologies are LCD (liquid crystal display) and OLED (organic light-emitting diode); many LCDs
Flat panels date from mid-20th century research, with commercial and consumer adoption accelerating in the 1990s
Advantages include a compact form factor, lower weight, energy efficiency, and the ability to produce high resolutions
In modern devices, flat-panel displays dominate consumer electronics, professional displays, and signage, with ongoing improvements in
