A CRT (cathode-ray tube) monitor is an analog display device that creates a visible image on the screen by directing three electron beams over millions of phosphor dots to make them light up. In a color monitor, the screen is composed of numerous stripes of alternating red, green, and blue phosphor dots, which get activated by the electrons and combine to make countless different hues.

The electron beam repetitively scans the entire front of the tube to "paint" and refresh the image nearly 100 times every second. Computer monitors and televisions that use CRT technology have large, heavy physical casings. The long length between the front screen and the back of the case is necessary to accommodate the length of the vacuum tube.

A Brief History of CRT Monitors

Cathode-ray tubes were commonly used in televisions and computer monitors throughout the mid-to-late 1900s. Throughout that time, manufacturers continually improved performance and resolution. Most computer monitors in the 1970s only displayed green text on a black screen. By 1990, IBM's Extended Graphics Array (XGA) display boasted 16.8 million colors in 800 x 600 pixel resolution.

Some gamers believe the faster refresh rate and minimal motion blur of CRT monitors creates a better gaming experience, especially for older titles with lower-resolution graphics.

In the early 2000s, advances in technology made flat-panel displays more accessible. These newer display types (LCD, plasma, and OLED) don't require a large casing and are more energy efficient. Manufacturing costs are lower than for CRT monitors, and flat-panel displays can be made in larger sizes than CRTs. These factors make flat-panel displays far more popular among consumers.

CRT monitors have heavy, bulky physical casings and comparatively small screens.

German physicists Julius Plücker and Johann Wilhelm Hittorf first observed cathode rays in 1869.

The Braun tube was the earliest version of a CRT. It was invented by German physicist Ferdinand Braun in 1897.

Japanese engineer Kenjiro Takayanagi demonstrated a CRT television in 1929.

German manufacturer Telefunken started making CRT television sets in 1934.

LCD screens surpassed CRTs in 2008.

Is a CRT Monitor Dangerous?

Depending on how old you are, you may remember your parents chiding you for sitting too close to the TV and claiming that it would damage your eyes. However, these fears seem to be largely unsubstantiated. There are some legitimate health and safety concerns with CRT monitors, but none of them link sitting too close to the screen with negative effects on eyesight.

A CRT monitor emits X-ray radiation, but it's a small amount that's regulated by the FDA.

There is a significant amount of stored electrical charge in a CRT, even one that's powered off. Breaking a CRT monitor or attempting to dismantle it without proper tools and training can lead to a severe electrical shock.

Puncturing the vacuum tube will create an implosion that can spray glass shards everywhere.

CRT monitors contain toxic materials, including mercury, which can leak out if the monitor breaks.

If you have a CRT monitor you no longer want, it's not safe to toss it in your trash can. You should contact your local authorities for information on safe disposal methods and/or recycling options.

Is CRT Better Than LCD?

While flat-panel LCD and OLED monitors and televisions are more common nowadays than CRTs, the older technology is still superior in some ways. A CRT monitor can display/refresh an image faster than an LCD screen. This means the monitor can respond faster to input and avoid motion-blur issues that are common in LCD screens. The color range and contrast is often better on a CRT, and this type of monitor supports deeper black tones. For some computer gamers, these advantages are enough to warrant scouring the internet for old CRT monitors.

Can You Still Buy CRT Monitors?

If you want to check out the benefits of a CRT monitor for yourself, prepare for a bit of work. Because CRTs aren't manufactured anymore, you won't be able to grab one at your local big box store. You'll probably be able to find a decent selection on eBay or through Craigslist or your local thrift store. CRT monitors can be pricey, especially if you have to pay for shipping, and it's important to make sure you choose a model that's compatible with your computer or gaming console.

Will CRT Monitors Make a Comeback?

When LCDs took over the market in the early 2000s, most companies drastically reduced their CRT manufacturing to account for the decreased demand. Sony stopped making CRT monitors in 2005, and 2008 was the last year Samsung introduced new CRT models. Despite pleas from a small number of passionate gamers who prefer CRT screens over LCDs, the lack of adequate market demand will likely prevent any major company from restarting production any time soon.

Flat-panel monitors are available in bigger screen sizes than CRTs, and they don't take up a lot of front-to-back space.

A TFT LCD monitor is a type of flat-panel display that works as either a computer monitor or as a display for a TV. TFT LCD is short for thin film transistor liquid crystal display. Most of the time, manufacturers shorten the term for such displays to LCD, dropping the TFT from the name since this abbreviation simply refers to the type of LCD monitor, and TFT is easily the most popular type.

A TFT LCD monitor.

The thin film transistor consists of a thin piece of a semiconductor material applied over a glass substrate. Each pixel has its own transistor along with the liquid crystal material. The liquid crystal material exhibits properties of both a liquid, because of its ability to change quickly, and a crystal, because of its ability to remain in an arranged position. The transistor applies a voltage to the pixel, determining its color and intensity. A pixel is short for picture element, and the tiny pixels blend together to create the image on a display.

Another name for a TFT LCD monitor is an active-matrix LCD. Although TFT is not the only active-matrix technology, it is overwhelmingly the most common type, causing some people use the two terms interchangeably. A TFT is only a small part of an active-matrix LCD, however. The term active-matrix refers to the ability of the monitor to control individual pixels and switch them quickly.

Active-matrix LCDs differ from passive-matrix LCDs in several ways. They have a high refresh rate, high contrast, and high response times, at least when compared to passive-matrix displays. A passive-matrix LCD is commonly found in a calculator display or a digital wristwatch, where the display contains a limited number of segments and does not require full color. Active-matrix displays usually are high-resolution, full-color LCDs, and they include those found in computer displays, cell phones, and TVs.

A few different types of thin film transistor technology may be are found in a TFT LCD monitor. The most common for computer displays and TVs is called a twisted nematic (TN) display, which features quick response times. TN displays do not excel in the areas of screen viewing angle and color reproduction, however. Another common monitor technology is IPS, short for in-plane switching. An IPS display offers great color and good viewing angles, but its refresh rates are slow.

What Does Liquid Crystal Display Monitor (LCD Monitor) Mean?

A liquid crystal display (LCD) monitor is a computer monitor or display that uses LCD technology to show clear images, and is found mostly in laptop computers and flat panel monitors. This technology has replaced the traditional cathode ray tube (CRT) monitors, which were the previous standard and once were considered to have better picture quality than early LCD variants. With the introduction of better LCD technology and its continuous improvement, LCD is now the clear leader over CRT, in terms of color and picture quality, not to mention capabilities for large resolutions. Also, LCD monitors may be made much more cheaply than CRT monitors.

Techopedia Explains Liquid Crystal Display Monitor (LCD Monitor)

Various different LCD technologies are used today, including:

In Plane Switching (IPS) Panel Technology: These panels are considered to have the best color accuracy, viewing angles and image quality in LCD technology.

Super Plane to Line Switching (PLS): Developed by Samsung, this LCD panel is very similar to the IPS panel but reportedly, it is 10 percent brighter, has wider viewing angles and is cheaper to produce.

Vertical Alignment (VA) Panel Technology: These panels are considered to be in the middle of TN and IPS technology. Compared to TN panels, they offer wider viewing angles and better color quality but have slower response times. They have higher contrast ratios, compared to the other panels but have a downside, in terms of color shifting, where the brightness display is unevenly distributed throughout the screen.

Twisted Nematic (TN) Panel Technology: These panels are the most commonly used type of panel in LCD technology. They are cheaper and offer faster response times, making them a preferred choice for gamers. The downside is that the viewing angles, contrast ratios and color production are considered the lowest of LCD panel types.

A CRT (cathode-ray tube) monitor is an analog display device that creates a visible image on the screen by directing three electron beams over millions of phosphor dots to make them light up. In a color monitor, the screen is composed of numerous stripes of alternating red, green, and blue phosphor dots, which get activated by the electrons and combine to make countless different hues.
