Light-emitting diodeA light-emitting diode (LED) is an electronic component that uses a semiconductor to emit light when current flows through it. Electrons in the semiconductor recombine with electron holes, thereby releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor.
MicroLEDMicroLED (also spelt micro-LED), also known as mLED or μLED is a flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements.
Flat-panel displayA flat-panel display (FPD) is an electronic display used to display visual content such as text or images. It is present in consumer, medical, transportation, and industrial equipment. Flat-panel displays are thin, lightweight, provide better linearity and are capable of higher resolution and contrast than typical consumer-grade TVs from earlier eras. They are usually less than 10 centimetres (3.9 in) thick.
Display deviceA display device is an output device for presentation of information in visual or tactile form (the latter used for example in tactile electronic displays for blind people). When the input information that is supplied has an electrical signal the display is called an electronic display. Common applications for electronic visual displays are television sets or computer monitors.
Video wallA video wall, television wall or TV wall is a special multi-monitor setup that consists of multiple computer monitors, video projectors, or television sets tiled together contiguously or overlapped in order to form one large screen. Typical display technologies include LCD panels, Direct View LED arrays, blended projection screens, Laser Phosphor Displays, and rear projection cubes. Jumbotron technology was also previously used.
PixelIn digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element of a raster image. In a display device, dot matrix printer, or ASCII art a pixel is the smallest element whose output can generally be controlled independently. The concept of a picture element dates to the earliest days of electronic imaging.
Variable-message signA variable- (also changeable-, electronic-, or dynamic-) message sign or message board, often abbreviated VMS, VMB, CMS, or DMS, and in the UK known as a matrix sign, is an electronic traffic sign often used on roadways to give travelers information about special events. Such signs warn of traffic congestion, accidents, incidents such as terrorist attacks, Amber/Silver/Blue Alerts, roadwork zones, or speed limits on a specific highway segment.
LightingLighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings.
Public transportPublic transport (also known as public transportation, public transit, mass transit, or simply transit) refers to forms of transport made available for use by the general public. Public transport systems typically operate on fixed routes and schedules and charge a standardized fare intended to cover operating costs, often supplemented by public funding where required. There is no universally fixed definition of which modes are included.SignageSignage is the design or use of signs and symbols to communicate a message. Signage also means signs collectively or being considered as a group. The term signage is documented to have been popularized in 1975 to 1980. Signs are any kind of visual graphics created to display information to a particular audience. This is typically manifested in the form of wayfinding information in places such as streets or on the inside and outside buildings.
Destination signA destination sign (North American English) or destination indicator/destination blind (British English) is a sign mounted on the front, side or rear of a public transport vehicle, such as a bus, tram/streetcar or light rail vehicle, that displays the vehicle's route number and destination, or the route's number and name on transit systems using route names.
Stage lightingStage lighting is the craft of lighting as it applies to the production of theater, dance, opera, and other performing arts. Several different types of stage lighting instruments are used in this discipline. In addition to basic lighting, modern stage lighting can also include special effects, such as lasers and fog machines. People who work on stage lighting are commonly referred to as lighting technicians or lighting designers.
