Flat-panel display

An electronic visual display built as a thin, flat panel. Common technologies include liquid-crystal displays, organic light-emitting diode displays, and plasma displays.

Liquid-crystal display: A display that controls light transmission through liquid crystals and color filters, usually with a backlight. LCDs form images by modulating light across a thin panel.
Thin-film transistor: A transistor formed in a thin semiconductor layer, commonly used to switch and control display pixels. TFTs let active-matrix panels address each pixel with precision.
Cathode-ray tube: An electronic display that forms images by scanning an electron beam across a phosphor-coated screen. Flat panels replaced bulky CRTs in most televisions and computer monitors.
Liquid-crystal display television: A television that uses an LCD panel to modulate light into moving images. LCD televisions became a widespread consumer use of flat-panel technology.
Display industry: The global sector that develops and manufactures screens, display materials, and related components. Flat-panel production reorganized display manufacturing around large-area glass and semiconductor processes.
OLED: A display technology in which organic semiconductor layers emit light when electrically driven. OLED pixels produce their own light, enabling thin panels without a separate backlight.
Color filter: An optical layer that selectively transmits portions of the visible spectrum to produce color. LCD panels use color filters to turn modulated backlight into colored subpixels.
MicroLED: A display technology using microscopic inorganic light-emitting diodes as individually controlled pixels. MicroLED is a newer emissive approach competing with established flat-panel technologies.
Computer monitor: An electronic screen that displays visual output from a computer. Flat panels transformed desktop monitors by reducing depth, weight, and power use.
Screen size: The physical dimensions of a display, commonly measured by its diagonal length. Thin panels enabled larger screens in homes and portable devices without CRT-sized cabinets.
