We all love plasma TVs, but behind the screen design, how does a plasma screen work?

It’s thanks to Mr. Noble and the gases he discovered that we are now able to watch this type of TV. The physics is quite simple really; xenon, helium and neon are used in many minute cells situated between two plates of glass. Electrodes are positioned between the glass plates and when an electric charge passes across the electrodes a difference in voltage is created ionising the gas and hence creating a plasma. Light photons are emitted due to ion collisions and excite a small amount of phosphor that coats each cell. Each pixel on the screen is made up of 3 sub-cells which are each coloured with a different phosphor (red, green or blue) and the colours merge to give the overall colour of the pixel.

See, told you it was simple.

It looks like SKY TV will be the first broadcaster to try to integrate 3D television broadcasts into everyone’s homes. The satellite operator recently trialled their new 3D technology at the ATP tennis finals and the visual results were excellent.

If you own a SKY HD box you will already be able to receive the 3D images (it looks like football will get the first outing) but you will need a 3D TV to view them. Gone and the two tone red and green glasses you had to wear to watch 3D TV in the 70s, but you will still need to wear stylish wrap-around lenses to get the full effect.

The system is scheduled for launch some time around the middle of 2010 so it might not be worth rushing out to buy your new 3D tele yet. But the visuals look stunning and we can’t wait to see what happens over the next few months before launch.

At this moment in time the best resolution you can choose is 1080p. But what is the difference between 1080p and 1080i?

The difference between ‘p’ and ‘i’ televisions is the difference in the way the television scans the picture. ‘i’ means interlaced scan, the television scans the picture in two passes each taking about 1/60th of a second. The first pass covers the odd lines and the second pass the even lines. This means a 1080i TV needs1/30th of a second to display the full image. ‘p’ stands for progressive scan, the image here is scanned in one pass. This gives a smoother clearer image and hence is the best option to go for (if you can afford it).

Giants Sony are working on a new TV screen display technology set to put them back in the race with Samsung, according to insider reports.

The new technology is not LED or OLED, but a new spin-off that sources claim is easier and cheaper to manufacture than current display technologies.

Since the launch of the Bravia LCD range of televisions, Sony have struggled to make a profit with current screen technologies and have even lost ground on the likes of Samsung and LG.

Sony have been working on this new step in their business development for the last 12 months, and will signify a great breakthrough.

Japanese manufacturer Kohjinsha have taken a big step in the netbook technology world and are set to release the industry’s first dual screen netbook, known as the Kohjinsha DZ series.

The netbook features two widescreen displays that support a 1024×600 resolution each and slide out from the centre to the left and right respectively. It also features a 1.3 megapixel camera, 1GB RAM, 160GB hard drive, Wifi, Bluetooth 2.1, 4.5 hour battery life, weighs in at just under 2 kilos and comes shipped with either Windows 7 or Linux operating systems.

The netbook is expected to go on sale in Japan on 11th December for around $1,100.
