A television set or television receiver, more commonly called the television, TV, TV set, telly, tele, or tube,television broadcasts, or as a computer monitor. Introduced in the late 1920s in mechanical form, television sets became a popular consumer product after World War II in electronic form, using cathode ray tube (CRT) technology. The addition of color to broadcast television after 1953 further increased the popularity of television sets in the 1960s, and an outdoor antenna became a common feature of suburban homes. The ubiquitous television set became the display device for the first recorded media for consumer use in the 1970s, such as Betamax, VHS; these were later succeeded by DVD. It has been used as a display device since the first generation of home computers (e.g. Timex Sinclair 1000) and dedicated video game consoles (e.g. Atari) in the 1980s. By the early 2010s, flat-panel television incorporating liquid-crystal display (LCD) technology, especially LED-backlit LCD technology, largely replaced CRT and other display technologies.USB device. Starting in the late 2010s, most flat panel TVs began to offer 4K and 8K resolutions.

Early electronic television sets were large and bulky, with analog circuits made of vacuum tubes. As an example, the RCA CT-100 color TV set used 36 vacuum tubes.transistor at Bell Labs, Sony founder Masaru Ibuka predicted in 1952 that the transition to electronic circuits made of transistors would lead to smaller and more portable television sets.solid-state television set was the 8-inch Sony TV8-301, developed in 1959 and released in 1960.million portable television sets worldwide.

By the late 1960s and early 1970s, color television had come into wide use. In Britain, BBC1, BBC2 and ITV were regularly broadcasting in colour by 1969.

Building on the work of Mohamed M. Atalla and Dawon Kahng on the MOSFET, Paul K. Weimer at RCA developed the thin-film transistor (TFT) in 1962.liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968.

In 1973, T. Peter Brody, J. A. Asars and G. D. Dixon at Westinghouse Research Laboratories demonstrated the first thin-film-transistor liquid-crystal display (TFT LCD).active-matrix liquid-crystal display (AM LCD) in 1974.

By 1982, pocket LCD TVs based on AM LCD technology were developed in Japan.Epson ET-10Sharp research team led by engineer T. Nagayasu demonstrated a 14-inch full-color LCD display,electronics industry that LCD would eventually replace cathode-ray tube (CRT) as the standard television display technology.

During the first decade of the 21st century, CRT "picture tube" display technology was almost entirely supplanted worldwide by flat-panel displays. By the early 2010s, LCD TVs, which increasingly used LED-backlit LCDs, accounted for the overwhelming majority of television sets being manufactured.

Television sets may employ one of several available display technologies. As of mid-2019, LCDs overwhelmingly predominate in new merchandise, but OLED displays are claiming an increasing market share as they become more affordable and DLP technology continues to offer some advantages in projection systems. The production of plasma and CRT displays has been completely discontinued.

The cathode ray tube (CRT) is a vacuum tube containing a so-called electron gun (or three for a color television) and a fluorescent screen where the television image is displayed.raster image onto the fluorescent screen. The CRT requires an evaacuated glass envelope, which is rather deep (well over half of the screen size), fairly heavy, and breakable. As a matter of radiation safety, both the face (panel) and back (funnel) were made of thick lead glass in order to reduce human exposure to harmful ionizing radiation (in the form of x-rays) produced when electrons accelerated using a high voltage (10-30kV) strike the screen. By the early 1970s, most color TVs replaced leaded glass in the face panel with vitrified strontium oxide glass,

In television sets (or most computer monitors that used CRT"s), the entire screen area is scanned repetitively (completing a full frame 25 or 30 times a second) in a fixed pattern called a raster. The image information is received in real-time from a video signal which controls the electrical current supplying the electron gun, or in color television each of the three electron guns whose beams land on phosphors of the three primary colors (red, green, and blue).magnetic deflection has been used to scan the image onto the face of the CRT; this involves a varying current applied to both the vertical and horizontal deflection coils placed around the neck of the tube just beyond the electron gun(s).

However, in the early to mid 2000s RPTV systems made a comeback as a cheaper alternative to contemporary LCD and Plasma TVs. They were larger and lighter than contemporary CRT TVs and had a flat screen just like LCD and Plasma, but unlike LCD and Plasma, RPTVs were often dimmer, had lower contrast ratios and viewing angles, image quality was affected by room lighting and suffered when compared with direct view CRTs,CRT projectors and were heavy, weighing up to 500 pounds.Ultra-high-performance lamps as their light source, which required periodic replacement partly because they dimmed with use but mainly because the operating bulb glass became weaker with ageing to the point where the bulb could eventually shatter often damaging the projection system. Those that used CRTs and lasers did not require replacement.

A plasma display panel (PDP) is a type of flat panel display common to large TV displays 30 inches (76 cm) or larger. They are called "plasma" displays because the technology utilizes small cells containing electrically charged ionized gases, or what are in essence chambers more commonly known as fluorescent lamps. Around 2014, television manufacturers were largely phasing out plasma TVs, because a plasma TV became higher cost and more difficult to make in 4k compared to LED or LCD.

Liquid-crystal-display televisions (LCD TV) are television sets that use Liquid-crystal displays to produce images. LCD televisions are much thinner and lighter than cathode ray tube (CRTs) of similar display size and are available in much larger sizes (e.g., 90-inch diagonal). When manufacturing costs fell, this combination of features made LCDs practical for television receivers.

In 2007, LCD televisions surpassed sales of CRT-based televisions globally for the first time,plasma display panel and rear-projection television. In the mid-2010s LCDs became, by far, the most widely produced and sold television display type.

An OLED (organic light-emitting diode) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound which emits light in response to an electric current. This layer of organic semiconductor is situated between two electrodes. Generally, at least one of these electrodes is transparent. OLEDs are used to create digital displays in devices such as television screens. It is also used for computer monitors, portable systems such as mobile phones, handheld game consoles and PDAs.

An OLED display works without a backlight. Thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display (LCD). In low ambient light conditions such as a dark room, an OLED screen can achieve a higher contrast ratio than an LCD, whether the LCD uses cold cathode fluorescent lamps or LED backlight.

Hospitality spaces are insecure with respect to content piracy, so many content providers require the use of Digital rights management. H.264 is not part of the ATSC 1.0 standard in North America, TV content in hospitality can include H.264 encoded video, so hospitality TVs include H.264 decoding. Managing dozens or hundreds of TVs can be time consuming, so hospitality TVs can be cloned by storing settings on a USB drive and restoring those settings quickly. Additionally, server-based and cloud-based management systems can monitor and configure an entire fleet of TVs.

Healthcare televisions include the provisions of hospitality TVs with additional features for usability and safety. They are designed for use in a healthcare setting in which the user may have limited mobility and audio/visual impairment. A key feature is the pillow speaker connection. Pillow speakers combine nurse call functions, TV remote control and a speaker for audio. In multiple occupancy rooms where several TVs are used in close proximity, the televisions can be programmed to respond to a remote control with unique codes so that each remote only controls one TV. Smaller TVs, also called bedside infotainment systems, have a full function keypad below the screen. This allows direct interaction without the use of a pillow speaker or remote.UL safety standard for televisions, UL62636-1, contains a special section (annex DVB) which outlines additional safety requirements for televisions used in healthcare.
