Labelled sketch of in-line gun and slot mask in a color picture tube. Labelled sketch of delta gun and shadow mask in a color picture tube. In a conventional shadow mask television design the electron guns at the back of the tube are arranged in a triangle. They are individually focused, with some difficulty, so that the three beams meet at a spot when they reach the shadow mask.

These all had snap-in connectors and were held in place by brackets instead of solder or screws. He envisioned a TV that would never require costly repairs, and early on started offering a 4-year warranty on picture tube, parts and labor. By the mid-1970s and the advent of solid-state electronics, Mathes had achieved results. The TV consisted of 11 parts: 7 circuit boards, a tuner, a picture tube and a transformer, plus the cabinet.

Philco's Predicta, 1958, in the collection of The Children's Museum of Indianapolis A Predicta mounted on a "barber pole" stand (2012) The Philco Predicta is a black and white television chassis style, made in several cabinet models with 17” or 21” screens, by the American company Philco from 1958 to 1960. The Predicta was marketed as the world's first swivel screen television, and has an iconic design by Catherine Winkler, with the picture tube (CRT) separated from the rest of the cabinet. The picture tube was surrounded in Eastman plastics' new product called “tenite”, which protected the glass and gave it its greenish tint. The Predicta also had a thinner picture tube than many other televisions at the time, which led it to be marketed as a more futuristic television set.

Unlike the winning field-sequential color system by CBS, the line sequential CTI system was all-electronic with no color scanning disk, and fully compatible with existing black and white receivers. Unlike the dot sequential RCA system, it used only one scanning tube in the camera and one picture tube in the receiver. CTI's camera used three lenses, behind which were mounted red, blue, and green color filters that produced three images side by side on a single scanning tube. At the receiver, the three images were received on three separate areas of a picture tube, each area treated with different phosphorescent compounds that glowed in red, blue, or green.

In 1963 Motorola introduced the first rectangular color picture tube, and in 1967 introduced the modular Quasar brand. In 1964 it opened its first research and development branch outside of the United States, in Israel under the management of Moses Basin. In 1974 Motorola sold its television business to the Japan-based Matsushita, the parent company of Panasonic.

After the video detector, the video is amplified and sent to the sync separator and then to the picture tube. At this point, we will now look at the audio section. The means of detection of the audio signal is by a 4.5 MHz trap coil/transformer. After that, it then goes to a 4.5 MHz amplifier.

Retrieved October 22, 2017. The model with the fully detached picture tube allowed the controls for the set to be next to the viewer, with the screen eight or more feet away. This feature provided Philco with an answer to Zenith's "Space Command" wireless remote control, which had been introduced the same year. Philco had the short lived “Directa” remote series shortly before being bought by Ford.

In 1949, the construction of the Rothe Erde industrial park began. The German division of Philips established an incandescent light and glass factory there, having taken over picture tube production in the area in 1954. Beginning around the turn of the century, and after Philips underwent changes to its operation, the industrial park Rothe Erde began to be used by a multitude of diverse businesses.

John Logie Baird FRSE (;"Baird": Collins English Dictionary – Complete & Unabridged 2012 Digital Edition. 13 August 188814 June 1946) was a Scottish inventor, electrical engineer, and innovator, demonstrating the world's first working television system on 26 January 1926. He also invented the first publicly demonstrated colour television system, and the first purely electronic colour television picture tube. In 1928 the Baird Television Development Company achieved the first transatlantic television transmission.

RCA XL-100 The XL-100 was a line of RCA completely solid-state (no vacuum tubes except picture tube) television sets that emerged in 1971 and continued into the late 1990s. The "XL" stands for extended life chassis while the 100 refers to RCA's emphasis of 100% solid-state chassis. They were the top of the line RCA color televisions that replaced the RCA "Vista" and "New Vista" color television series.

When Les Hoffman entered the television manufacturing business, he was a newcomer. He needed to keep his costs down and did not have the resources like the established companies such as Zenith or Philco. After World War II ended, there was considerable surplus materials that needed to be cleared out of company and government stores. Television picture tubes require a protective safety glass in front of it to prevent injury if the picture tube imploded.

This was a cathode ray tube memory, similar in many aspects to an early TV picture tube or oscilloscope tube. An electron gun sent a beam of electrons to the far end of the tube, where they impacted a screen. The beam would be deflected to land at a particular spot on the screen. The beam could then build up a negative charge at that point, or change a charge that was already there.

Yangmei has high-tech industry in the area, with Chunghwa Picture Tube having a factory in the city. One of the largest clusters of TFT-LCD plants are located in the area, Yangmei is also a transport hub with several container terminals present in the city. Maersk Taiwan maintains a distribution center in Yangmei. A fair amount of light industry is also present, with Youth Industrial Park (幼獅工業區) being home to much traditional industry.

Quasar is an American brand of electronics, first used by Motorola in 1967 for a model line of transistorized color televisions. These TVs were marketed as containing all serviceable parts in a drawer beside the picture tube. It was then established as a subsidiary brand, with all Motorola-manufactured televisions being sold as Quasar by Motorola. Motorola sold its television business to Matsushita Electric, now Panasonic, in 1974 who continued producing and marketing televisions under the Quasar brand until 2005.

In 1988, a Sharp research team led by engineer T. Nagayasu demonstrated a 14-inch full- color LCD display, which convinced the 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.

The output voltage of a tripler is in practice below three times the peak input voltage due to their high impedance, caused in part by the fact that as each capacitor in the chain supplies power to the next, it partially discharges, losing voltage doing so. Triplers were commonly used in color television receivers to provide the high voltage for the cathode ray tube (CRT, picture tube). Triplers are still used in high voltage supplies such as copiers, laser printers, bug zappers and electroshock weapons.

A monochrome monitor is a type of CRT computer display which was very common in the early days of computing, from the 1960s through the 1980s, before color monitors became popular. The most important component in the monitor is the picture tube. CRT basically means cathode ray tube. The CRT use cathode-ray-tube technology to display images, so they are large, bulky and heavy like conventional or old televisions, because old televisions also used the CRT technology only to display the television films or television images.

RCA eventually solved the problem of displaying the color images with their introduction of the shadow mask. The shadow mask consists of a thin sheet of steel with tiny holes photo etched into it, placed just behind the front surface of the picture tube. Three guns, arranged in a triangle, were all aimed at the holes. Stray electrons at the edge of the beam were cut off by the mask, creating a sharply focused spot that was small enough to hit a single colored phosphor on the screen.

A degaussing in progress Many televisions and monitors automatically degauss their picture tube when switched on, before an image is displayed. The high current surge that takes place during this automatic degauss is the cause of an audible "thunk" or loud hum, which can be heard (and felt) when televisions and CRT computer monitors are switched on. Visually, this causes the image to shake dramatically for a short period of time. A degauss option is also usually available for manual selection in the operations menu in such appliances.

Creating colors by mixing colored lights (usually red, green and blue) in various proportions is the additive method of color reproduction. LCD, LED, plasma and CRT (picture tube) color video displays all use this method. If one of these displays is examined with a sufficiently strong magnifier, it will be seen that each pixel is actually composed of red, green and blue sub-pixels which blend at normal viewing distances, reproducing a wide range of colors as well as white and shades of gray. This is also known as the RGB color model.

Because of the every-household presence of the conventional television picture tube (Cathode-Ray Tube), it may be helpful to think of its principles of operation. Though the IOT does not produce a glowing phosphor output, internally many principles are the same. IOTs have been described as a cross between a klystron and a triode, hence Eimac's trade name for them, Klystrode. They have an electron gun like a klystron, but with a control grid in front of it like a triode, with a very close spacing of around 0.1 mm.

RCA was responsible for creating a series of innovative products, ranging from octal base metal tubes co-developed with General Electric before World War II, to miniaturized Nuvistor tubes used in the tuners of the New Vista series of TV sets. The Nuvistor tubes were a last major vacuum tube innovation, along with General Electric's Compactron, and were meant to compete with the newly introduced transistor. By 1975, RCA had completely switched from tubes to solid-state devices in their television sets, except for the cathode ray tube (CRT) picture tube.

Voltage ramps are produced that the monitor uses to steer the electron beam over the face of the phosphor screen of the cathode ray tube. Another signal is generated that controls the brightness of the line. The cathode ray tube is a Samsung model 240RB40 monochrome unit measuring 9 × 11 inches, displaying a picture of 240 mm diagonal; it is an off-the-shelf picture tube manufactured for small black/white television sets. The brightness of the CRT is controlled using a circular knob on the back of the display.

The Trinitron design incorporates two unique features: the single-gun three- cathode picture tube, and the vertically aligned aperture grille. The single gun consists of a long-necked tube with a single electrode at its base, flaring out into a horizontally-aligned rectangular shape with three vertically-aligned rectangular cathodes inside. Each cathode is fed the amplified signal from one of the decoded RGB signals. The electrons from the cathodes are all aimed toward a single point at the back of the screen where they hit the aperture grille, a steel sheet with vertical slots cut in it.

But with the recent popularity of newer television technologies such as LCD, plasma, or DLP, some stores now describe the sets that still use a picture tube as tube TVs or CRT TVs. ; Two-door coupe: Before four-door cars started to have coupe-like styling in recent years, coupe mostly referred to 2-door cars. Examples of 4-door cars that have coupe used as a marketing term are the BMW X6 SUV and the Dodge Charger sedan which re-uses the name of a 1970s 2-door car. ; Ultimate Doom: Before Doom II, Ultimate Doom was originally just simply Doom.

The first production PPI was devised at the Telecommunications Research Establishment, UK and was first introduced in the H2S radar blind-bombing system of World War II. Originally, data was displayed in real time on a cathode ray tube, and thus the only way to store the information received was by taking a photograph of the screen. Philo Taylor Farnsworth, the American inventor of all-electronic television in September 1927, contributed to this in an important way. Farnsworth refined a version of his picture tube (cathode ray tube, or CRT) and called it an "Iatron;" generically known as a storage tube. It could store an image for milliseconds to minutes and even hours.

In modern displays, the LOPT, voltage multiplier and rectifier are often integrated into a single package on the main circuit board. There is usually a thickly insulated wire from the LOPT to the anode terminal (covered by a rubber cap) on the side of the picture tube. One advantage of operating the transformer at the flyback frequency is that it can be much smaller and lighter than a comparable transformer operating at mains (line) frequency. Another advantage is that it provides a failsafe mechanism — should the horizontal deflection circuitry fail, the flyback transformer will cease operating and shut down the rest of the display, preventing the screen burn that would otherwise result from a stationary electron beam.

Entertainment Weekly writer Bruce Fretts particularly praised Andre Braugher's performance: "It's not often you actually witness a TV star being born... The moment the galvanic actor steps onto the screen, though, he owns it." The New York Times television critic John J. O'Connor praised the performance of Jon Polito, and said the role could be "the kind of career break Joe Pesci found in the Lethal Weapon movies".Kalat, p. 74 Mike Boone of The Gazette praised Belzer's performance and the hand-held camera style of photography, adding, "But if your picture tube blew Sunday night, you could still listen to an hour of the hippest, funniest dialogue on TV." Not all reviews were positive.

An HP 8590L (low cost version of 8591c), video out connected to a Cadco channel modulator operating above 550 MHz, with a Radio Shack black and white TV (picture tube) tuned to UHF channels to see the picture. Add to that a comb generator with 4-6 CW tones, an HP Calan 1776 "portable" spectrum analyzer.. Not all amplifiers contained a good return path test point, so the repair lab was asked to modify some line extender diplex filters to pass the forward, and divert the return path to an F connector. A pad socket was also converted. Any signal entering an amplifier with an amplitude above -45 dBmV was located and fixed.

The Curtis Mathes Corporation was founded in 1957 and shortly thereafter entered the television industry, founding plants in Tarrant and Dallas Counties and in Athens, Texas, eventually moving most of its manufacturing to a huge Athens facility. From 1968 to 1988 it was the only fully American-owned electronics firm and the only American television manufacturer. In the late 1960s, Leonard L. Northrup, Jr., bought a controlling interest in Donmark Corporation, a manufacturer of residential air conditioning and heating equipment from his lifelong friend Curtis Mathes, Sr., as Curtis Mathes moved toward electronics. During the next few years Curtis Mathes worked to design a modular TV and modular TV parts and chassis, so that warranty service would involve quickly switching a part, tube, tuner or picture tube.

The name "Phase Alternating Line" describes the way that the phase of part of the colour information on the video signal is reversed with each line, which automatically corrects phase errors in the transmission of the signal by cancelling them out, at the expense of vertical frame colour resolution. Lines where the colour phase is reversed compared to NTSC are often called PAL or phase-alternation lines, which justifies one of the expansions of the acronym, while the other lines are called NTSC lines. Early PAL receivers relied on the human eye to do that cancelling; however, this resulted in a comb-like effect known as Hanover bars on larger phase errors. Thus, most receivers now use a chrominance analogue delay line, which stores the received colour information on each line of display; an average of the colour information from the previous line and the current line is then used to drive the picture tube.

Sundance was an arcade vector game released in 1979. Producer Cinematronics planned to manufacture about 1000 Sundance units, but sales suffered from a combination of poor gameplay and an abnormally high rate of manufacturing defects. The fallout rate in production was about 50%, the vector monitor (made by an outside vendor) had a defective picture tube that would arc and burn out if the game was left in certain positions during shipping, and according to programmer Tim Skelly, the circuit boards required a lot of cut-and-jumpering between mother and daughter boards that also made for a very fragile setup. The units that survived to reach arcade floors were not a hit with gamers—Skelly himself reportedly felt that the gameplay lacked the "anxiety element" necessary in a good game and asked Cinematronics not to release it, and in an April 1983 interview with Video Games Magazine he referred to Sundance as "a total dog".

If they just wanted to watch the color broadcast in black-and-white they would have to buy and install an external "adapter" which produced a monochrome, but smaller, picture (using only 405 lines of a standard set's 525). If they wished to watch a color broadcast in color they would have to buy and install a "converter", which paired the adapter with a spinning tricolor disk that slid in front of the screen (a magnifying lens was usually included.) However a converter was limited to television screens of up to around 12 inches (30 centimeters). So those who wanted to keep their existing large-screen black- and-white TVs would have to buy a "companion set" (also called a "slave- unit"), which was a separate unit containing an enclosed picture tube with color disk, and which came with a cord that plugged into the circuitry of the adjacent black-and-white TV. For many of the ten to twelve million owners of existing sets these options seemed too complicated or expensive, especially if compatible color ended up making the CBS color system redundant or even obsolete. And the FCC was allowing work to continue on compatible color.

On the Friday before Premiere's airing, Allen B. DuMont, founder of DuMont Laboratories and the DuMont Television Network, contacted the FCC requesting that it postpone CBS's commercial color programming in light of recent improvements to RCA's compatible tricolor picture tube. His request was turned down, so while Premiere was airing Dr. DuMont invited members of the press to his Passaic, New Jersey laboratories to view a demonstration of color on this improved RCA tube. Closed-circuit color still images were displayed which to the viewing press seemed similar in quality to the CBS color broadcast which could be viewed in a separate room. NBC had already announced that starting July 9 it would begin authorized experimental broadcasts in New York City of RCA compatible color, with public demonstrations of the WNBT-TV broadcasts on RCA color receivers In addition, the National Television System Committee (NTSC), which had helped craft the original U.S. monochrome television broadcasting standards in 1941, had already reorganized in order to implement an all-industry plan which would pool together the knowledge and resources of the NTSC, RCA, General Electric and others to create a new "composite" compatible color system which it hoped would prove acceptable to the FCC.
