Some early flat screen TVs used cathode ray tubes, but the flat faced tubes were harder to make and heaver than the older curved faced tubes. When newer designs (e.g. plasma, LCD, LED) came out that naturally produced flat screens and were lighter weight than cathode ray tubes, they rapidly made flat screen cathode ray tube TVs obsolete.
It is used for LCD & Plasma Technology.
Transistor radios have NO tubes. They have (guess what) transistors.
Cathode Ray Tubes are potentially dangerous because they are vacuum sealed and can implode. This can cause the shattered glass to fly outward and also exposes the toxic coating inside of the tube.
Could you please explain your question more fully?Is it the last part of a longer question?There are many types and sizes of cathode ray tubes, which weigh different amounts.RegardsGeorge
Hell no pee head
Cathode Ray Tubes are becoming obselete with the adcent of flat screen TVs and High definition broadcasting. Plasma and LCD screens do not use CRTs.
Yes. Cathode ray tubes, (CRTs) will continue to exist, but will increasingly become obsolete.
Cathode ray tubes are the screens of old fashioned televisions and computer monitors.
Today you can find cathode ray tubes (crts) in TVs that are not plasma or LCD, along with some microwave ovens. They are also used in ATM machines, security cameras, and oscilloscopes among other things.
Not so much with modern TVs; cathode ray tubes used powerful magnets to focus the electron stream. Modern LCD and Plasma TVs don't use magnets. Some televisions do use magnets, It just depends on which one. :D
The two most recognizable types of electron tubes are vacuum tubes and cathode ray tubes. Vacuum tubes are electronic devices that control electrical signals, while cathode ray tubes are used in older television and computer monitors to display images.
Cathode Ray Tube (or CRT) - the older type of tv set or monitor, and the LCD display (or flat-screen)
Cathode Ray Tubes (CRT) were used in monitors (the non-flatscreen ones) which were common in older televisions.
It's a CRT which stands for Cathode Ray tube.
because cathode ray tube is the heart of the television.
CRT stands for "cathode ray tube" and they are a special kind of vaccuum tube that displays the image in old, standard TVs. LCD stands for "liquid crystal display" and it is a thin, flat electronic display that uses light-modulating properties of liquid crystals in order to give off the image.
Some older televisions had cathode-ray tubes that used electromagnets to direct the electron beam, but most modern televisions use LCD or OLED technology which do not utilize magnets. However, some televisions may have small magnets in speakers or for certain functions like attaching a remote control to the TV.
