Obviously, weвЂ™re just simplifying things here. Other CRTs, such as those used in oscilloscopes and in some early arcade video games, directly plot an image by tracing lines on the phosphor screen with a single electron gun, more like an electronic Etch-A-Sketch. Chemistrygod / ShutterstockД¬RT televisions and most CRT computer monitors draw an image on the screen line by line, from top to bottom, in a raster pattern, 30 or 60 times a second. A simplified diagram of a cathode ray tube. The intensity of the beam can be modulated as well, which changes the brightness in certain parts of the image.

In the case of a color CRT display, there are three electron guns: one each for red, green, and blue, and they are aimed at colored phosphors that glow with those colors when hit by the corresponding beams. How Do CRTs Work?Д¬RTs are sealed glass vacuum tubes that contain three major components: an electron source (often called an electron gun), an electromagnetic deflection system (that steers the electron beam), and a phosphorescent screen that glows when hit by the electron beam. Later, computers began to use CRT monitors as output devices as well, making them more interactive and eliminating the need for continuous printed paper output. Over time, other scientists discovered that CRTs could be used to display moving images without the need for mechanical moving parts, providing a key element to the commercialization of television. BraunвЂ™s diagram of his original 1897 cathode ray tube design. In 1897, a German engineer named Karl Ferdinand Braun added a phosphorescent screen and magnetic deflection control to create the first cathode ray tube, which he used to display the waveform of AC current like an oscilloscope. Why вЂњcathode ray?вЂќ Before the discovery of the electron, scientists called streams of electrons вЂњcathode rays,вЂќ because these mysterious rays were first seen being emitted by a cathode (a negatively charged electrode), casting shadows inside a vacuum tube.

When someone says вЂњa CRT,вЂќ they might also be referring to a TV set or monitor that uses a CRT instead of the actual cathode ray tube itself. CRTs are electronic image display devices that have the advantage of showing information dynamically without the need for moving parts. However, before you go buy that CRT screen, here are some reasons you might NOT want to spend your hard-earned money on it they are mostly big and bulky, have less resolution and picture quality, consume lots of powerВ - typically twice to three times that of an FlatscreenВ TV.In the context of electronics, CRT stands for вЂњcathode ray tube.вЂќ ItвЂ™s a technical term for the glass picture tube inside of a vintage TV set or computer monitor-the kind used before flat-screen displays became common. So those are some of the advantages of the good-old screens. With Flatscreen TVs, even the slightest scratch on the screen might make you want purchase another one. The screen at home is almost half my image and it is still going! ThatвЂ™s just awesome.

CRTs are a lot more durable than your Flatscreen alternatives.

The old-screen TVs donвЂ™t have these problems. You would agree with me if youвЂ™ve seen вЂњghostвЂќ shadowy images when you try to watch your Flatscreen from the sides.

CRTs have wide viewing angle compared to Flatscreen TVs.

You can take a look at our list of prices of select flatscreen TVs in Uganda. They are usually more than 50% less than the cost of their flatscreen counterparts. In Uganda, a 17 Inch CRT TV Screen costs about Ugx 300, 000 вЂ“ 500,000.

Low cost: This is the probably reason why you want to go for a CRT screen.Flatscreen and Smart TV on contrary require lots of initial setup such as connecting to the internet, installing and updating apps, complex User interfaces among others. Tube TV is easy to set-up, and will work well in a variety of locations and ambient light conditions.Here are four reasons you want to keep your Tube TV Related post: A complete beginnerвЂ™s guide to Flat screen and smart TVs So why would you still want to go for CRT TVs or keep your existing one? Flatscreen TVs offer better picture quality since they are digital-ready, consume less power and have lots of functionality.
