Old Television Disposal and Recycling

Among the technical developments that have come to dominate our lives, television is surely one of the top ten. The average household watches television for seven hours per day, which helps to explain why news, sports, and educational entities, as well as advertisers, value the device for communication. The device we call the television is really a television receiver that is the end point of a broadcast system that starts with a television camera or transmitter and requires a complicated network of broadcast transmitters using ground-based towers, cables, and satellites to deliver the original picture to our living rooms.

The U. By electronic methods, 30 images per second, each broken into these horizontal lines, are scanned onto the screen. The development of the television occurred over a number of years, in many countries, and using a wide application of sciences, including electricity, mechanical engineering, electromagnetism, sound technology, and electrochemistry.

No single person invented the television; instead, it is a compilation of inventions perfected by fierce competition. Chemicals that are conductors of electricity were among the first discoveries leading to the TV. Sir William Crookes invented the cathode ray tube in , but these discoveries took many years to merge into the common ground of television.

Paul Nipkow of Germany made the first crude television in His mechanical system used a scanning disk with small holes to pick up image fragments and imprint them on a light-sensitive selenium tube. A receiver reassembled the picture. In , W. Hallwachs applied photoelectric cells in cameras; cathode rays were demonstrated as devices for reassembling the image at the receiver by Boris Rosing of Russia and A.

Campbell-Swinton of Great Britain, both working independently in Countless radio pioneers including Thomas Edison invented methods of broadcasting television signals. Jenkins of the United States constructed the first true television sets in the s by combining Nipkow's mechanical scanning disk with vacuum-tube amplifiers and photoelectric cells. By , mechanical systems for transmitting black-and-white images were replaced completely by electronic methods that could generate hundreds of horizontal bands at 30 frames per second.

Vladimir K. Zworykin, a Russian immigrant who first worked for Westinghouse then RCA, patented an electronic camera tube based on the cathode tube. Philo T. Farnsworth and Allen B. Dumont, both Americans, developed a pickup tube that became the home television receiver by The Columbia Broadcasting System CBS had entered the color TV fray and battled with RCA to perfect color television, initially with mechanical methods until an all-electronic color system could be developed.

Commercial color television broadcasts were underway in the United States by The television consists of four principle sets of parts, including the exterior or housing, the audio reception and speaker system, the picture tube, and a complicated mass of electronics including cable and antennae input and output devices, a built-in antenna in most sets, a remote control receiver, computer chips, and access buttons.

The remote control or "clicker" may be considered a fifth set of parts. The housing of the set is made of injection-molded plastic, although wood cabinets are still available for some models. Metals and plastics also comprise the audio system. The picture tube requires precision-made glass, fluorescent chemical coatings, and electronic attachments around and at the rear of the tube.

The tube is supported inside the housing by brackets and braces molded into the housing. The antennae and most of the input-output connections are made of metal, and some are coated with special metals or plastic to improve the quality of the connection or insulate the device.

The chips, of course, are made of metal, solder, and silicon. Prismatic scanning disc mount made by C. Francis Jenkins in To the surprise of most people, television transmission began almost 25 years before the end of World War II.

John Logie Baird, in England, and C. Francis Jenkins, in the United States, both made public demonstrations of television in Unlike post-war electronic televisions, these early systems used mechanical scanning methods. Jenkins made significant contributions to optical transmission research during the s. During , he constructed mechanical prismatic disc scanners to transmit images.

These scanners focused and refracted light through prisms ground into the edges of overlapping glass discs. As the discs rotated, a point of light scanned horizontally and vertically across a light-sensitive surface. This generated electrical signals necessary for transmission. In Jenkins sent facsimiles of photographs by telephone, and the following year transmitted images of President Harding and others by radio with an improved scanner.

Unlike television, however, these first tests only sent still pictures. Jenkins publicly broadcast moving images with his equipment in His first minute broadcast showed in silhouette the motions of a small operating windmill. By , he had experimental television stations operating in New York and Washington D.

He sold receiver kits to those wishing to view his telecasts and encouraged amateur participation. With other companies, Jenkins contributed to a small, short-lived mechanical television "boom.

The design of the television requires input and teamwork on the part of a range of design engineers. Audio, video, plastics, fiber Diagram of a television receiver.

A new design of television may have one or many new applications of technology as features. It may only be a different size of an existing model, or it may include an array of new features such as an improved sound system, a remote control that also controls other entertainment devices, and an improved screen or picture, such as the flat black screens that have entered the marketplace recently. Conceptual plans for the new set are produced by the engineering team.

The concept may change and be redrawn many times before the design is preliminarily approved for manufacture. The engineering specialists then select and design the components of the set, and a prototype is made to prove out the design. The prototype is essential, not only for confirming the design, appearance, and function of the set, but also for production engineers to determine the production processes, machining, tools, robots, and modifications to existing factory production lines that also have to be designed or modified to suit the proposed new design.

When the prototype passes rigid reviews and is approved for manufacture by management, detailed plans and specifications for design and production of the model are produced. Raw materials and components manufactured by others can then be ordered, the production line can be constructed and tested, and the first sets can begin their ride down the assembly line.

It may also have a dark tint added to the face plate glass, either during production of the glass or by application directly to the inside of the screen. Darker face plates produce improved picture contrast. When the tube is manufactured, a water suspension of phosphor chemicals is allowed to settle on the inside of the face plate, and this coating is then overlaid with a thin film of aluminum that lets electrons pass through.

The aluminum serves as a mirror to prevent light from bouncing back into the tube. Glass for picture tubes is supplied by a limited number of manufacturers in Japan and Germany. Quantities of the quality of glass needed for picture tubes are limited, and the emergence of large-screen sets has created a shortage in this portion of the industry. The large screens are also very heavy, so flat-panel displays using plasma-addressed liquid crystal PALC displays were developed in the s.

This gas plasma technology uses electrodes to excite layers of neon or magnesium oxide, so they release ultraviolet radiation that activates the phosphor on the back of the television screen. Because the gas is trapped in a thin layer, the screen can also be thin and lightweight. A shadow mask with , holes lies immediately behind the phosphor screen; the holes are precisely machined to align the colors emitted by three electron beams. Today's best picture tubes have shadow masks that are manufactured from a nickel-iron alloy called Invar; lesser quality sets have masks of iron.

The alloy allows the tube to operate at a higher temperature without distorting the picture, and higher temperatures allow brighter pictures. Rare-earth elements have also been added to the phosphor coating inside the tube to improve brightness. The electrons are fired by three tubular, metal electron guns that are carefully seated in the neck, or narrow end, of the tube. After the electron guns are placed inside the tube, the picture tube is evacuated to a near vacuum so air does not interfere with the movement of the electrons.

The small opening at the rear of the tube is sealed with a fitted electrical plug that will be positioned near the back of the set. A deflection yoke, consisting of several electromagnetic coils, is fitted around the outside of the neck of the picture tube. The coils cause pulses of high voltage to direct the scanning electron beams in the proper direction and speed. The electrons are fired by three tubular, metal electron guns seated in the neck, or narrow end, of the picture tube. A color selection filter with , holes lies immediately behind the television screen; the holes are precisely machined to align the colors emitted by three electron beams.

As with all precision devices, quality control for the manufacture of the television is a rigid process. Inspections, laboratory testing, and field testing are performed during the development of prototypes and throughout manufacture so the resulting television is not only technologically sound but safe for use in homes and businesses. There are no byproducts from the manufacture of the television, although many other devices are a part of the television "family" and are often produced by the same manufacturer.

These include the remote control, computer monitors, video recorders VCRs , laser disc players, and a host of devices that may require compatible design and components.

Specialized televisions are produced for some industries, including television studios and mobile broadcast facilities, hospitals, and for surveillance applications for public safety and use in inaccessible or dangerous locations.

Wastes may include metals, plastics, glass, and chemicals. Metals, plastics, and glass are isolated and recycled unless they have been specially treated or coated. Chemicals are carefully monitored and controlled; often, they can be purified and recycled, so disposal of hazardous wastes can be minimized. Hazardous waste plans are in effect in all stages of manufacture, both to minimize quantities of waste and to protect workers. The future of television is now. This system produces a movie-quality picture by using a 1,line picture on a "letter-box" format screen with a 16 to nine width to height ratio.

High-quality, flat screens suitable for HDTV are being perfected using synthetic diamond film to emit electrons in the first application of synthetic diamonds in electronic components.

Other developments in the receiver include gold-plated jacks, an internal polarity switch on large screens that compensates for the effect of Earth's magnetic field on image reception, accessories to eliminate ghosts on the screen, the Invar shadow mask to improve brightness, and audio amplifiers. Liquid crystal display LCD technology is also advancing rapidly as an alternative to the cumbersome television screen.

Assorted computer chips add functions like channel labeling, time and data displays, swap and freeze motions, parental channel control, touch screens, and a range of channel-surfing options. Digital television of the future will allow the viewer to manipulate the angle of the camera, communicate with the sports commentator, and splice and edit movies on screen.

Two-way TV will also be possible. Current screens may be used thanks to converter boxes that change the analog signal that presently energizes the phosphors on the back of your television screen to digital signals that are subject to less distortion—and are the language of computers.

The government has scrapped import duty on open cell TV panel used to make television sets, as it aims to boost local manufacturing by lowering input costs for TV makers who have been complaining about a slump in demand. The decision to remove 5 percent customs duty will help reduce manufacturing cost by around 3 percent but it wasn't immediately clear if all TV makers will pass on the benefit to consumers. Finance Ministry in a notification said customs duty on "open-cell Most TV makers import these panels.

A television set or television receiver , more commonly called a television , TV , TV set , or telly , is a device that combines a tuner, display, and loudspeakers, for the purpose of viewing and hearing television broadcasting through satellites or cables, or viewing and hearing a computer. Introduced in the late s 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 further increased the popularity of television sets in the s, and an outdoor antenna became a common feature of suburban homes. The ubiquitous television set became the display device for the first recorded media in the s, such as Betamax , VHS and later DVD.

Samsung Looks To Make Smart TVs In India To Challenge Xiaomi, Others In Budget Segment

TV has long been an essential part of any household in modern society. For many years, it was the primary source of visual entertainment via which one could watch their favorite daily soaps, live sporting events, informative programs, and news. With increase in internet speed and connectivity, demand for online content and streaming video services such as Netflix, Hulu and Amazon Prime have grown. Over the years, TVs have undergone massive transformation in their size, shape, design and the way it is viewed. By enhancing the dynamic range and color, saturation and contrast differences are impacted, thereby improving the experience of UHD TVs. Smart TV refers to internet-connected digital television that can offer much wider range of entertainment features, including using Apps, web browsing, wireless streaming and other additional services.

The falling price of a TV set is the story of the American economy. This means that once again I am poking around online for a new TV. Between and , per the Bureau of Labor Statistics , the average price of TVs slipped almost 20 percent. Though this argument holds no water when you consider that plenty of more essential things such as health care have gotten more expensive, the falling price of TVs speaks to evolutions in both how people buy and use TVs — and how TV makers themselves actually make money.

Among the technical developments that have come to dominate our lives, television is surely one of the top ten. The average household watches television for seven hours per day, which helps to explain why news, sports, and educational entities, as well as advertisers, value the device for communication.

A year after Samsung made its exit from the television manufacturing business in India, the South Korean tech giant is now planning to return to challenge up and coming players. The potential move from Samsung comes in the backdrop of government scrapping import duty on the open cell panels or TV displays, one of the biggest components in television manufacturing.

The absence of a robust homegrown electronics ecosystem is hurting the ambitious targets set by the Indian Space Research Organisation Isro , which has lined up more than 60 missions over the next five years. These include building new generation communication and earth observation satellites, heavier rockets, return missions to the moon and Mars, and its first human space flight endeavour.

The history of the Polar Company began in October when several like-minded students of the Moscow Aviation Institute decided to start their own production of television sets. Their decision was well motivated: at that time, high quality foreign-made televisions were not imported and thus unknown in the country, while domestic TVs were poorly made. It was decided to arrange production of the high quality and not expensive TV sets for Russian consumers. But the most important factor is that it should be capable of operating in difficult Russian working conditions: with unstable power voltage, far away from TV signal stations, with non-standard cable network signal. The Company's first TV sets were of the so-called 4th generation, equipped with a remote control unit. In experts of the Polar Design Bureau gained enough experience to develop and introduce their own electronic structure for the Company's 6th generation TVs.
