Modern TVs are more complicated than ever before. If you’ve found yourself browsing one of our guides and felt stumped by some of the acronyms or tech specs, we’ve summarized the most common terms below:

LCD: LCD stands for liquid crystal display, and it’s the most common kind of television besides OLED (defined below). LCD TVs shine an LED backlight through a panel of liquid crystal, a malleable substance that reacts to electricity, opening or closing when jolted. In LCD TVs, the liquid crystal opens to allow the backlight through or closes to block it. The specific details of the opening/closing are dependent upon the arrangement of the pixels: The most common LCD arrangements are Vertical Alignment (VA) and In-Plane Switching (IPS), with the former tending to produce higher contrast and the latter tending to produce wider viewing angles. All so-called “LED” TVs are really LCD TVs, as are all current QLED and ULED TVs.

OLED: An organic light-emitting diode, or OLED, TV creates light inside each individual pixel without using a backlight and can dim each pixel individually all the way down to black, which LCD TVs can’t do. This tech gives an OLED TV an infinite contrast ratio and other benefits to help create an overall better-looking image, although at considerable additional cost. You can read more about OLED technology in this article.

Mini-LEDs: Every LCD TV made today currently uses LEDs to produce the light that shines through the LCD panel. Most TVs use LED lights that pass through a diffuser to light up the entire LCD screen. Mini-LEDs, which some TVs use, are much smaller than traditional LEDs, so TV makers can install more of them and thus create more zones of local dimming, which means less blooming or halos around bright objects. Mini-LEDs are completely different from micro-LEDs, an available (though very expensive) technology that employs individual red, green, and blue LEDs to produce an image without needing an LCD panel at all.

Nits: Also called candelas per square meter (cd/m²), this unit of luminance measures how much light a TV can produce. Previously, TVs could output 200 to 300 nits, and standard dynamic range (SDR) content was graded and mastered with 100 nits as the standard. With high dynamic range (HDR), content is mastered with 1,000, 4,000, or 10,000 nits as the standard; so, the more nits an HDR TV can display, the more accurately it can display the highlights in HDR material without having to reduce the brightness of the highlights or clip them.

Wide color gamut: Ultra HD content has a wider color gamut than standard HDTV content; right now, most UHD content is mastered with the same DCI/P3 color gamut used in theatrical cinema (the ultimate goal is the even larger Rec. 2020 color gamut). This expanded color gamut allows a TV to display richer reds, blues, and greens than ever before. Some TVs use quantum-dot technology to produce this wider color gamut.

Quantum dots: Quantum dots are a color-enhancing technology primarily found in LCD TVs (though some 2022 OLED TVs now have them as well). Chiefly employed as a filter that’s painted onto a substrate, quantum dots are microscopic nano-crystals that, when struck with blue light, produce very vivid red or green light (depending upon the size of the crystal). Quantum dots are the primary technology that allows LCD TVs to produce the wide color gamut required to display HDR content properly, as they greatly increase the color saturation of red and green.

Refresh rate: All digital displays (including TVs) have what’s called a refresh rate, measured in hertz (Hz), shorthand for cycles per second. A TV’s refresh rate refers to how quickly it displays new incoming video information on a nanosecond-to-nanosecond basis. While there are many possible refresh rates, most TVs come with either a 60 Hz refresh rate (meaning 60 screen refreshes per second) or a 120 Hz refresh rate (120 screen refreshes per second). Ideally, a TV will have the highest refresh rate possible, but there are diminishing returns for higher refresh rates during many types of content. A 120 Hz TV has advantages when watching 24p content or mitigating judder (definitions below), and tends to produce less input lag when playing video games, but it won’t provide advantages for most forms of cable TV or streaming content. In 2022, some manufacturers introduced 144 Hz TVs meant to appeal specifically to gamers, but the majority of TVs still have 60 or 120 Hz refresh rates.

Judder: This term refers to a slightly jerky motion that can occur when 24p film content appears on a TV with a 60 Hz refresh rate. In such situations, to make 24 frames match up to the 60 Hz display, half of the frames appear two times and the other half appear three times. This display technique causes judder, which is most noticeable on panning shots. Some 120 Hz displays avoid this effect by repeating each film frame five times, while some 60 Hz panels run at 48 Hz to show each frame twice.

Motion smoothing: Motion smoothing, sometimes called MEMC (Motion Estimation/Motion Compensation), refers to a TV’s ability to intelligently create new frames to create smoother-looking or less juddery motion. Most modern TVs can artificially increase their refresh rates to smooth out fast or difficult sequences, but the efficacy of this motion smoothing is often dependent upon the TV’s native refresh rate. Motion smoothing is also the cause of the “soap opera effect,” where cinematic/24p content looks more like a daytime soap opera due to the insertion of unnecessary frames. The best TVs come with multiple motion smoothing presets, and some even allow the user to fine-tune the degree of judder reduction and frame interpolation employed. When used correctly, motion smoothing can make content like sports and nature documentaries look more realistic, but we prefer it be turned off for content like premium TV, movies, and video games.

Plasma TV production ended in 2015. However, they are still being used and sold in the secondary market. As a result, it"s helpful to understand how a Plasma TV works and how it compares to an LCD TV.

Within each cell, a narrow gap that contains an insulating layer, address electrode, and display electrode, separates two glass panels. In this process, neon-xenon gas is injected and sealed in plasma form during the manufacturing process.

When a Plasma TV is in use, the gas is electrically charged at specific intervals. The charged gas then strikes red, green, and blue phosphors, creating an image on the screen.

Each group of red, green, and blue phosphors is called a pixel (picture element — the individual red, green, and blue phosphors are called sub-pixels). Since Plasma TV pixels generate their light, they are referred to as "emissive" displays.

Plasma TVs can be made thin. However, even though the need for the bulky picture tube and electron beam scanning of those older CRT TVs is not required, Plasma TVs still employ burning phosphors to generate an image. As a result, Plasma TVs suffer from some of the drawbacks of CRT TVs, such as heat generation and possible screen burn-in of static images.

LCD crystals do not produce light, so they need an external source, such as fluorescent (CCFL/​HCFL) or LEDs, for the picture created by the LCD to become visible to the viewer.

Unlike a Plasma TV, since there are no phosphors that light up, less power is needed for operation, and the light source in an LCD TV generates less heat than a Plasma TV. There is no radiation emitted from the screen.

Plasma TVs are more vulnerable to burn-in of static images. However, this problem diminished over the years due to "pixel orbiting" and related technologies.

Potentially shorter display lifespan. Early models had 30,000 hours or 8 hours of viewing a day for nine years, which was less than LCD. However, screen lifespan improved and 60,000-hour lifespan rating became the standard, with some sets rated as high as 100,000 hours, due to technology improvements.

Not as good at tracking motion (fast-moving objects may exhibit lag artifacts). However, this has with the implementation of 120Hz screen refresh rates and 240Hz processing in most LCD sets, but that can result in the "Soap Opera Effect," in which film-based content sources look more like a videotape than film.

Narrower effective side-to-side viewing angle than Plasma. On LCD TVs, it is common to notice color fading or color shifting as you move your viewing position further to either side of the center point.

Although LCD TVs do not suffer from burn-in susceptibility, single pixels can burn out, causing small but visible, black or white dots to appear on the screen. Individual pixels are not fixable. Replacing the whole screen is the sole option if the pixel burnout becomes unbearable.

An LCD TV was typically more expensive than an equivalent-sized (and equivalent featured) Plasma TV. However, that is no longer a factor, since companies have ceased manufacturing Plasma TVs.

Manufacturers chose to incorporate 4K resolution only in LCD TVs, using LED back and edge-lighting, and, in the case of LG and Sony, incorporating 4K into TVs using OLED technology.

Although it was possible to incorporate 4K resolution display capability into a Plasma TV, it was prohibitively expensive. When the sales of Plasma TVs started declining, TV makers decided against bringing consumer-based 4K Ultra HD Plasma TVs to market, which was another factor in their demise. The only 4K Ultra HD Plasma TVs manufactured were for commercial application use.

Television, sometimes shortened to TV, is a telecommunication medium for transmitting moving images and sound. The term can refer to a television set, or the medium of television transmission. Television is a mass medium for advertising, entertainment, news, and sports.

The availability of various types of archival storage media such as Betamax and VHS tapes, LaserDiscs, high-capacity hard disk drives, CDs, DVDs, flash drives, high-definition HD DVDs and Blu-ray Discs, and cloud digital video recorders has enabled viewers to watch pre-recorded material—such as movies—at home on their own time schedule. For many reasons, especially the convenience of remote retrieval, the storage of television and video programming now also occurs on the cloud (such as the video-on-demand service by Netflix). At the end of the first decade of the 2000s, digital television transmissions greatly increased in popularity. Another development was the move from standard-definition television (SDTV) (576i, with 576 interlaced lines of resolution and 480i) to high-definition television (HDTV), which provides a resolution that is substantially higher. HDTV may be transmitted in different formats: 1080p, 1080i and 720p. Since 2010, with the invention of smart television, Internet television has increased the availability of television programs and movies via the Internet through streaming video services such as Netflix, Amazon Prime Video, iPlayer and Hulu.

In 2013, 79% of the world"s households owned a television set.cathode-ray tube (CRT) screen displays with compact, energy-efficient, flat-panel alternative technologies such as LCDs (both fluorescent-backlit and LED), OLED displays, and plasma displays was a hardware revolution that began with computer monitors in the late 1990s. Most television sets sold in the 2000s were flat-panel, mainly LEDs. Major manufacturers announced the discontinuation of CRT, Digital Light Processing (DLP), plasma, and even fluorescent-backlit LCDs by the mid-2010s.Web 2.0 functions became the dominant form of television by the late 2010s.

The slang term telly is more common in the UK. The slang term "the tube" or the "boob tube" derives from the bulky cathode-ray tube used on most TVs until the advent of flat-screen TVs. Another slang term for the TV is "idiot box".

In 1926, Hungarian engineer Kálmán Tihanyi designed a television system using fully electronic scanning and display elements and employing the principle of "charge storage" within the scanning (or "camera") tube.Hungary in March 1926 for a television system he called "Radioskop".RCA"s "iconoscope" in 1931, the U.S. patent for Tihanyi"s transmitting tube would not be granted until May 1939. The patent for his receiving tube had been granted the previous October. Both patents had been purchased by RCA prior to their approval.Kenjiro Takayanagi demonstrated a TV system with a 40-line resolution that employed a CRT display.

The world"s first 625-line television standard was designed in the Soviet Union in 1944 and became a national standard in 1946.CCIR standard.Kálmán Tihanyi described the principle of plasma display, the first flat panel display system.

Early electronic television sets were large and bulky, with analog circuits made of vacuum tubes. Following the invention of the first working 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.

Digital television (DTV) is the transmission of audio and video by digitally processed and multiplexed signals, in contrast to the totally analog and channel separated signals used by analog television. Due to data compression, digital television can support more than one program in the same channel bandwidth.computers. It was not until the 1990s that digital television became possible.bandwidth requirements of uncompressed digital video,Mbit/s for a standard-definition television (SDTV) signal,Gbit/s for high-definition television (HDTV).

In the mid-1980s, as Japanese consumer electronics firms forged ahead with the development of HDTV technology, the MUSE analog format proposed by NHK, a Japanese company, was seen as a pacesetter that threatened to eclipse U.S. electronics companies" technologies. Until June 1990, the Japanese MUSE standard, based on an analog system, was the front-runner among the more than 23 other technical concepts under consideration. Then, a U.S. company, General Instrument, demonstrated the possibility of a digital television signal. This breakthrough was of such significance that the FCC was persuaded to delay its decision on an ATV standard until a digitally-based standard could be developed.

In March 1990, when it became clear that a digital standard was possible, the FCC made a number of critical decisions. First, the Commission declared that the new ATV standard must be more than an enhanced analog signal, but be able to provide a genuine HDTV signal with at least twice the resolution of existing television images.(7) Then, to ensure that viewers who did not wish to buy a new digital television set could continue to receive conventional television broadcasts, it dictated that the new ATV standard must be capable of being "simulcast" on different channels.(8)The new ATV standard also allowed the new DTV signal to be based on entirely new design principles. Although incompatible with the existing NTSC standard, the new DTV standard would be able to incorporate many improvements.

The last standards adopted by the FCC did not require a single standard for scanning formats, aspect ratios, or lines of resolution. This compromise resulted from a dispute between the consumer electronics industry (joined by some broadcasters) and the computer industry (joined by the film industry and some public interest groups) over which of the two scanning processes—interlaced or progressive—would be best suited for the newer digital HDTV compatible display devices.Liquid-crystal (LCD), for example, which are better suited to a more frequent progressive refresh rate.

The advent of digital television allowed innovations like smart television sets. A smart television, sometimes referred to as connected TV or hybrid TV, is a television set or set-top box with integrated Internet and Web 2.0 features, and is an example of technological convergence between computers, television sets and set-top boxes. Besides the traditional functions of television sets and set-top boxes provided through traditional Broadcasting media, these devices can also provide Internet TV, online interactive media, over-the-top content, as well as on-demand streaming media, and home networking access. These TVs come pre-loaded with an operating system.

Smart TV should not to be confused with Internet TV, Internet Protocol television (IPTV) or with Web TV. Internet television refers to the receiving of television content over the Internet instead of by traditional systems—terrestrial, cable and satellite (although Internet itself is received by these methods). IPTV is one of the emerging Internet television technology standards for use by television networks. Web television (WebTV) is a term used for programs created by a wide variety of companies and individuals for broadcast on Internet TV. A first patent was filed in 1994

With the widespread adoption of cable across the United States in the 1970s and 1980s, terrestrial television broadcasts have been in decline; in 2013 it was estimated that about 7% of US households used an antenna.digital terrestrial television broadcasts, which offered pristine image quality over very large areas, and offered an alternative to cable television (CATV) for cord cutters. All other countries around the world are also in the process of either shutting down analog terrestrial television or switching over to digital terrestrial television.

Cable television is a system of broadcasting television programming to paying subscribers via radio frequency (RF) signals transmitted through coaxial cables or light pulses through fiber-optic cables. This contrasts with traditional terrestrial television, in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television. In the 2000s, FM radio programming, high-speed Internet, telephone service, and similar non-television services may also be provided through these cables. The abbreviation CATV is sometimes used for cable television in the United States. It originally stood for Community Access Television or Community Antenna Television, from cable television"s origins in 1948: in areas where over-the-air reception was limited by distance from transmitters or mountainous terrain, large "community antennas" were constructed, and cable was run from them to individual homes.

The most common method of reception is direct-broadcast satellite television (DBSTV), also known as "direct to home" (DTH).direct broadcast satellite on the Ku wavelength and are completely digital.television receive-only. These systems received analog signals transmitted in the C-band spectrum from FSS type satellites, and required the use of large dishes. Consequently, these systems were nicknamed "big dish" systems, and were more expensive and less popular.

The direct-broadcast satellite television signals were earlier analog signals and later digital signals, both of which require a compatible receiver. Digital signals may include high-definition television (HDTV). Some transmissions and channels are free-to-air or free-to-view, while many other channels are pay television requiring a subscription.Arthur C. Clarke proposed a worldwide communications system which would function by means of three satellites equally spaced apart in earth orbit.Franklin Institute"s Stuart Ballantine Medal in 1963.

Internet television (Internet TV) (or online television) is the digital distribution of television content via the Internet as opposed to traditional systems like terrestrial, cable, and satellite, although the Internet itself is received by terrestrial, cable, or satellite methods. Internet television is a general term that covers the delivery of television series, and other video content, over the Internet by video streaming technology, typically by major traditional television broadcasters. Internet television should not be confused with Smart TV, IPTV or with Web TV. Smart television refers to the television set which has a built-in operating system. Internet Protocol television (IPTV) is one of the emerging Internet television technology standards for use by television networks. Web television is a term used for programs created by a wide variety of companies and individuals for broadcast on Internet television.

A television set, also called a television receiver, television, TV set, TV, or "telly", is a device that combines a tuner, display, an amplifier, and speakers for the purpose of viewing television and hearing its audio components. 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 tubes. The addition of color to broadcast television after 1953 further increased the popularity of television sets and an outdoor antenna became a common feature of suburban homes. The ubiquitous television set became the display device for recorded media in the 1970s, such as Betamax and VHS, which enabled viewers to record TV shows and watch prerecorded movies. In the subsequent decades, Television sets were used to watch DVDs and Blu-ray Discs of movies and other content. Major TV manufacturers announced the discontinuation of CRT, DLP, plasma and fluorescent-backlit LCDs by the mid-2010s. Televisions since 2010s mostly use LEDs.

Digital Light Processing (DLP) is a type of video projector technology that uses a digital micromirror device. Some DLPs have a TV tuner, which makes them a type of TV display. It was originally developed in 1987 by Dr. Larry Hornbeck of Texas Instruments. While the DLP imaging device was invented by Texas Instruments, the first DLP based projector was introduced by Digital Projection Ltd in 1997. Digital Projection and Texas Instruments were both awarded Emmy Awards in 1998 for invention of the DLP projector technology. DLP is used in a variety of display applications from traditional static displays to interactive displays and also non-traditional embedded applications including medical, security, and industrial uses. DLP technology is used in DLP front projectors (standalone projection units for classrooms and business primarily), but also in private homes; in these cases, the image is projected onto a projection screen. DLP is also used in DLP rear projection television sets and digital signs. It is also used in about 85% of digital cinema projection.

A plasma display panel (PDP) is a type of flat panel display common to large television displays 30 inches (76 cm) or larger. They are called "plasma" displays because the technology uses small cells containing electrically charged ionized gases, or what are in essence chambers more commonly known as fluorescent lamps.

Liquid-crystal-display televisions (LCD TV) are television sets that use LCD display technology 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. LCDs come in two types: those using cold cathode fluorescent lamps, simply called LCDs and those using LED as backlight called as LEDs.

In 2007, LCD television sets surpassed sales of CRT-based television sets worldwide for the first time, and their sales figures relative to other technologies accelerated. LCD television sets have quickly displaced the only major competitors in the large-screen market, the Plasma display panel and rear-projection television.OLEDs, FED and SED, but as of 2014

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. OLEDs are expected to replace other forms of display in near future.

Low-definition television or LDTV refers to television systems that have a lower screen resolution than standard-definition television systems such 240p (320*240). It is used in handheld television. The most common source of LDTV programming is the Internet, where mass distribution of higher-resolution video files could overwhelm computer servers and take too long to download. Many mobile phones and portable devices such as Apple"s iPod Nano, or Sony"s PlayStation Portable use LDTV video, as higher-resolution files would be excessive to the needs of their small screens (320×240 and 480×272 pixels respectively). The current generation of iPod Nanos have LDTV screens, as do the first three generations of iPod Touch and iPhone (480×320). For the first years of its existence, YouTube offered only one, low-definition resolution of 320x240p at 30fps or less. A standard, consumer grade videotape can be considered SDTV due to its resolution (approximately 360 × 480i/576i).

Standard-definition television or SDTV refers to two different resolutions: 576i, with 576 interlaced lines of resolution, derived from the European-developed PAL and SECAM systems; and 480i based on the American National Television System Committee NTSC system. SDTV is a television system that uses a resolution that is not considered to be either high-definition television (720p, 1080i, 1080p, 1440p, 4K UHDTV, and 8K UHD) or enhanced-definition television (EDTV 480p). In North America, digital SDTV is broadcast in the same 4:3 aspect ratio as NTSC signals with widescreen content being center cut.16:9 aspect ratio, with the transition occurring between the mid-1990s and mid-2000s. Older programs with a 4:3 aspect ratio are shown in the United States as 4:3 with non-ATSC countries preferring to reduce the horizontal resolution by anamorphically scaling a pillarboxed image.

Ultra-high-definition television (also known as Super Hi-Vision, Ultra HD television, UltraHD, UHDTV, or UHD) includes 4K UHD (2160p) and 8K UHD (4320p), which are two digital video formats proposed by NHK Science & Technology Research Laboratories and defined and approved by the International Telecommunication Union (ITU). The Consumer Electronics Association announced on 17 October 2012, that "Ultra High Definition", or "Ultra HD", would be used for displays that have an aspect ratio of at least 16:9 and at least one digital input capable of carrying and presenting natural video at a minimum resolution of 3840×2160 pixels.

Getting TV programming shown to the public can happen in many other ways. After production, the next step is to market and deliver the product to whichever markets are open to using it. This typically happens on two levels:

Around the world, broadcast television is financed by government, advertising, licensing (a form of tax), subscription, or any combination of these. To protect revenues, subscription television channels are usually encrypted to ensure that only subscribers receive the decryption codes to see the signal. Unencrypted channels are known as free to air or FTA. In 2009, the global TV market represented 1,217.2 million TV households with at least one TV and total revenues of 268.9 billion EUR (declining 1.2% compared to 2008).

The first official, paid television advertisement was broadcast in the United States on 1 July 1941, over New York station WNBT (now WNBC) before a baseball game between the Brooklyn Dodgers and Philadelphia Phillies. The announcement for Bulova watches, for which the company paid anywhere from $4.00 to $9.00 (reports vary), displayed a WNBT test pattern modified to look like a clock with the hands showing the time. The Bulova logo, with the phrase "Bulova Watch Time", was shown in the lower right-hand quadrant of the test pattern while the second hand swept around the dial for one minute.ITV on 22 September 1955, advertising Gibbs SR toothpaste. The first TV ad broadcast in Asia was on Nippon Television in Tokyo on 28 August 1953, advertising Seikosha (now Seiko), which also displayed a clock with the current time.

U.S. advertising rates are determined primarily by Nielsen ratings. The time of the day and popularity of the channel determine how much a TV commercial can cost. For example, it can cost approximately $750,000 for a 30-second block of commercial time during the highly popular singing competition Super Bowl can cost several million dollars. Conversely, lesser-viewed time slots, such as early mornings and weekday afternoons, are often sold in bulk to producers of infomercials at far lower rates. In recent years, the paid program or infomercial has become common, usually in lengths of 30 minutes or one hour. Some drug companies and other businesses have even created "news" items for broadcast, known in the industry as video news releases, paying program directors to use them.

The TV regulator oversees TV advertising in the United Kingdom. Its restrictions have applied since the early days of commercially funded TV. Despite this, an early TV mogul, Roy Thomson, likened the broadcasting licence as being a "licence to print money".ITV, Channel 4, and Channel 5 can show an average of only seven minutes of advertising per hour (eight minutes in the peak period). Other broadcasters must average no more than nine minutes (twelve in the peak). This means that many imported TV shows from the U.S. have unnatural pauses where the British company does not use the narrative breaks intended for more frequent U.S. advertising. Advertisements must not be inserted in the course of certain specific proscribed types of programs which last less than half an hour in scheduled duration; this list includes any news or current affairs programs, documentaries, and programs for children; additionally, advertisements may not be carried in a program designed and broadcast for reception in schools or in any religious broadcasting service or other devotional program or during a formal Royal ceremony or occasion. There also must be clear demarcations in time between the programs and the advertisements. The BBC, being strictly non-commercial, is not allowed to show advertisements on television in the U.K., although it has many advertising-funded channels abroad. The majority of its budget comes from television license fees (see below) and broadcast syndication, the sale of content to other broadcasters.

Some TV channels are partly funded from subscriptions; therefore, the signals are encrypted during broadcast to ensure that only the paying subscribers have access to the decryption codes to watch pay television or specialty channels. Most subscription services are also funded by advertising.

The British Broadcasting Corporation"s TV service carries no television advertising on its UK channels and is funded by an annual television licence paid by the occupiers of premises receiving live telecasts. As of 2012Freeview.

Broadcast programming, or TV listings in the United Kingdom, is the practice of organizing television programs in a schedule, with broadcast automation used to regularly change the scheduling of TV programs to build an audience for a new show, retain that audience, or compete with other broadcasters" programs.

With high lead content in CRTs and the rapid diffusion of new flat-panel display technologies, some of which (LCDs) use lamps which contain mercury, there is growing concern about electronic waste from discarded televisions. Related occupational health concerns exist, as well, for disassemblers removing copper wiring and other materials from CRTs. Further environmental concerns related to television design and use relate to the devices" increasing electrical energy requirements.
