After the invention of colour TVs in 1950s, the next best invention to capture the minds of people has been the Flat Panel TV technology. With the option to treat the Flat TVs as a part of the wall than as a part of the furniture, people have gone gaga over it.

The rage with which it is being sold, the CRT models may soon become antique pieces. But again there are many CRT loyalists who contend this, as there are many technical aspects where Flat TVs, Plasma or LCD, are yet to beat the old rival the CRT tube technology.

The conventional tube TVs have lost out due to the following reasons:

• They are heavy because of the sealed glass picture tube
• They have deep cabinet structure. Its long electron gun creates images by firing continuous beams of electrons, horizontally scanning the phosphor dot coated front panel.
• They are out of focus at the screen’s edges because of wider angle of firing. In spite of their excellent picture quality and affordable prices, they are getting replaced at a faster rate. Looks matter a lot!
