The VT100 is a video terminal, introduced in August 1978 by Digital Equipment Corporation (DEC). It was one of the first terminals to support ANSI escape codes for cursor control and other tasks, and added a number of extended codes for special features like controlling the status lights on the keyboard. This led to rapid uptake of the ANSI standard, which became the de facto standard for hardware video terminals and later terminal emulators.
A flip clock is an electromechanical, digital time keeping device with the time indicated by numbers that are sequentially revealed by a split-flap display. The study, collection and repair of flip clocks is termed horopalettology.
A graphics tablet is a computer input device that enables a user to hand draw or paint images, animations and graphics, with a special pen-like stylus, similar to the way a person draws pictures with a pencil and paper by hand.
A graphics card is a computer expansion card that generates a feed of graphics output to a display device such as a monitor. Graphics cards are sometimes called discrete or dedicated graphics cards to emphasize their distinction to an integrated graphics processor on the motherboard or the central processing unit (CPU). A graphics processing unit (GPU) that performs the necessary computations is the main component in a graphics card, but the acronym "GPU" is sometimes also used to erroneously refer to the graphics card as a whole.
A digital on-screen graphic, digitally originated graphic is a watermark-like station logo that most television broadcasters overlay over a portion of the screen area of their programs to identify the channel. They are thus a form of permanent visual station identification, increasing brand recognition and asserting ownership of the video signal.
A scoreboard is a large board for publicly displaying the score in a game. Most levels of sport from high school and above use at least one scoreboard for keeping score, measuring time, and displaying statistics. Scoreboards in the past used a mechanical clock and numeral cards to display the score. When a point was made, a person would put the appropriate digits on a hook. Most modern scoreboards use electromechanical or electronic means of displaying the score. In these, digits are often composed of large dot-matrix or seven-segment displays made of incandescent bulbs, light-emitting diodes, or electromechanical flip segments. An official or neutral person will operate the scoreboard, using a control panel.
A character generator, often abbreviated as CG, is a device or software that produces static or animated text for keying into a video stream. Modern character generators are computer-based, and they can generate graphics as well as text.
Rendition, Inc., was a maker of 3D computer graphics chipsets in the mid to late 1990s. They were known for products such as the Vérité 1000 and Vérité 2x00 and for being one of the first 3D chipset makers to directly work with Quake developer John Carmack to make a hardware-accelerated version of the game (vQuake). Rendition's major competitor at the time was 3Dfx. Their proprietary rendering APIs were Speedy3D and RRedline.
The flip-disc display is an electromechanical dot matrix display technology used for large outdoor signs, normally those that will be exposed to direct sunlight. Flip-disc technology has been used for external destination signs on buses and trains across North America, Europe and Australia, as well as for variable-message signs on highways. It has also been used extensively on public information displays. A few game shows have also used flip-disc displays, including Canadian shows like Just Like Mom, The Joke's on Us and Uh Oh!, but most notably the American game show Family Feud from 1976 to 1995, and its British version Family Fortunes from 1980 to 2002. The Polish version of Family Feud, Familiada, still uses this board, which was bought from the Swedish version of the show.
A digital clock displays the time digitally, as opposed to an analogue clock.
Orchid Technology was a privately held company founded by Le Nhon Bui in 1982.
A dot-matrix display is a low-cost electronic digital display device that displays information on machines such as clocks, watches, calculators, and many other devices requiring a simple alphanumeric display device of limited resolution.
The Cifra 3 is a digital flip clock manufactured by Solari di Udine, S.p.A., Italy designed by Italian architect Gino Valle (1923–2003) in 1965, with significant contribution from John Myer, a Belgian inventor. The Cifra 3 is widely considered a masterpiece of industrial design, using a split-flap display to display hours and minutes. The clock is on permanent display in the "Humble Masterpieces" exhibition at the Museum of Modern Art in New York and holds a place in the permanent collection of the Science Museum in London.
A destination sign or destination indicator/destination blind 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. The main such sign, mounted on the front of the vehicle, usually located above the windshield, is often called the headsign, most likely from the fact that these signs are located on the front, or head, end of the vehicle. Depending on the type of the sign, it might also display intermediate points on the current route, or a road that comprises a significant amount of the route, especially if the route is particularly long and its final terminus by itself is not very helpful in determining where the vehicle is going.
A text display is an electronic alphanumeric display device that is mainly or only capable of showing text, or extremely limited graphic characters. This includes electromechanical split-flap displays, vane displays, and flip-disc displays; all-electronic liquid-crystal displays, incandescent eggcrate displays, LED displays, and vacuum fluorescent displays; and even electric nixie tubes.
A station clock is a clock at a railway station that provides a standard indication of time to both passengers and railway staff.
A platform display, destination display or train describer is supplementing the destination sign on arriving trains giving passengers an advance information. Historically they did only show the next destination and sometimes the type of train. In later usage they were replaced by passenger information display systems (PIDS) allowing for real-time passenger information.
Solari di Udine SpA is an Italian company that designs and manufactures public information displays, historically split-flap displays. The company was founded in 1725 in Udine, a small city in northeastern Italy. Initially, the company specialized in clocks for towers. It began working with designer Gino Valle after World War II, and developed signs with four flaps, each with ten digits, to display the time. The company eventually designed displays with 40 flaps, with the help of Belgian inventor John Myer. The new displays could include numbers and letters, allowing for a much wider use.
The Main Concourse is the primary concourse of Grand Central Terminal, a railway station in Midtown Manhattan, New York City. The space is located at the center of the terminal's station building.
