Samsung Slims Down CRT TVs

Samsung SDI is using the now ancient CRT technology to compete with LCD and Plasmas with a TV set that's far thinner than conventional CRTs.

With all the talk of Plasma and LCD technology, it seems that Cathode Ray Technology (CRT) technology just won’t go away. Samsung SDI has come up with a 32in CRT television that’s only 38cm deep. While this is still thicker than a Plasma or LCD television it’s still thin enough to compete with rear projection TVs.


The company isn’t stopping there either with plans to create even thinner TVs that can go head to head with LCDs and Plasmas. Plans are already underway for a (moglossary:CRT) with a depth of only 20cm to enter production by 2007. The road map also includes plans for TVs with a diagonal size of up to 34in, and full High Definition compatible models with a resolution of 1,920 x 1,080.

To achieve this thinner design Samsung has increased the deflection angle of the electron beam by the yoke from 105 degrees to 125 degrees. To do this the company has had to solve various key technical issues, such as increased power consumption, loss of electron beam focus and funnel glass cracking.

The reason Samsung is continuing with CRT development in one of cost, as the established technology is far cheaper to produce than LCD and Plasma. At an estimated price of around $1000 or about £550, the thinner TVs would cost about the same as current sets.
