CRT is a mature technology, less expensive, higher contrast, and still produces brighter pictures than a flat-panel display of the same display area. These advantages are slowly being eroded with better flat-panel technology. The cons are more than offsetting its pros. Since CRT uses accelerated electrons and a phosphor screen, it has a little more harmful radiation (if not properly shielded), it uses more energy and generates more heat, and at the end of its life, produces more hazardous materials, not to mention that it occupies a larger footprint and weighs more than a flat-panel display.

What else can I help you with?
How was the Cathode Ray Tube Amusement device invented?
Cathode ray tube amusement device was created in 1947.
What is the negatively charged electrode of a cathode ray tube?
The negatively charged electrode of a cathode ray tube (CRT) is the cathode. The tube is a cathode ray tube, and electrons stream off the cathode, are accelerated across the evacuated space and "directed" either electromagnetically or electrostatically, and then strike the phosphor coating on the positively charged anode at a "location" determined by the "directing" elements.
Why deflection is necessary in cathode ray tube?
It is not necessary in a cathode ray tube, it is a side effect and is needed in the calculations to ensure that there are no errors.
Can an animal see electrons emitted by a cathode ray tube?
no
Who invented the cathode ray tube in the 1970s?
William Crookes invented cathode ray tubes.The earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897.
What following piece of equipment was used by jj Thomson to find electrons?
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.
What is the full meaning of CRT in computer?
A "CRT" is a cathode ray tube. An old style computer monitor (not computer).
What is the flow of a cathode ray inside a cathode ray tube?
Electrons.
Why television are also known as cathode ray tube?

Which of these appliances uses cathode ray tube - electric fan refrigerator or rice cooker?
None of these appliances use a cathode ray tube. Older type TVs used a cathode ray tube, its common name was the picture tube.

What is a cartrode ray tube?
Probably a mis-spelling of "cathode ray tube".
What is the negatively charged electrode of a cathode ray tube?
The negatively charged electrode of a cathode ray tube (CRT) is the cathode. The tube is a cathode ray tube, and electrons stream off the cathode, are accelerated across the evacuated space and "directed" either electromagnetically or electrostatically, and then strike the phosphor coating on the positively charged anode at a "location" determined by the "directing" elements.
