One of the newest additions in television technology, Plasma Televisions are the 21st century display devices which are fast becoming a popular choice among television viewers. Plasma televisions have higher resolution and quality performance than other conventional televisions; they guarantee crisp and clear images, and superior quality.
Plasma televisions became a reality after the successful invention of the plasma display panel in 1964, by Donald L. Bitzer and H. Gene Slottow at the University of Illinois at Urbana-Champaign. Embracing a unique technology, Plasma televisions produce pictures from a combination of inert gases such as xenon and neon. When the gas is charged using electrodes, the atoms collide with each other and release energy in the form of invisible ultra violet (UV) light. The light is then focused on the three phosphors (red, green, and blue) and a brilliant picture is produced.
Plasma televisions come as Enhanced Definition TV (EDTV) with a resolution of 852×480 and the Higher Definition TV (HDTV) featuring a native resolution of 1024×768. Plasma televisions have a high widescreen aspect ratio – the ratio between the width and height of the screen. As plasma televisions do not use any electron beams like the conventional ones, they are immune to the effects of magnetic fields. They offer a wider viewing angle and accurate image reproduction. Plasma televisions are slim and space-saving and can even be hung on a wall. Moreover, most of the plasma televisions come with a flat screen which eliminates edge distortion.
Plasma televisions can be used in meeting rooms, corporate offices, and network control rooms. They are ideal choices for home-theater enthusiasts. On account of quality performance in ambient light, plasma televisions are widely opted for teleconferencing.
A countless number of retail and online stores specialize in plasma television sale. Due to their inherent merits, plasma televisions are becoming the most demanded alternative to the standard CRT and projection televisions.

Toshiba has released details of its new gaming/entertainment laptop that uses Intel’s performance Core i7 processor and carries the name Qosmio.A red beast of a machine, the Qosmio X305-Q725 is stacked with the new low cost Intel Quad Core Q9000 processor along with hybrid storage and a powerful NVIDIA GeForce 9800M GTX GPU that can handle all of today’s hottest games. All of this power comes in a chassis that’s a bit bulky but that has some good-looking styling and curves, too.
The Toshiba Qosmio x305 notebook was spotted doing what it does best, playing games on the Windows operating system. What else would you expect from a Microsoft event? Notice the four sweet looking Harman Kardon stereo speakers located at each corner around the keyboard. The features of the notebook are impressive as you can see from the list below.
- 3GHz Intel Core 2 Extreme dual-core Processor
- NVIDIA Geforce 9800M GTX graphics with 1GB RAM
- Up to 4GB DDR3 RAM (This is a Montevina platform)
- Dual 200GB 7200rpm hard drives
- 17in 1440×900 native resolution (WSXGA+)
- HDMI and S/PDIF outputs
- 4.1-channel Harmon Kardon speakers
Like many desktop replacement systems, the Qosmio X305-Q725’s battery life won’t even come close to the battery life you’ll get with an ultraportable or a netbook, but that’s not the point. Most users who are interested in a desktop replacement system require power, and they know that they’ll have to stay tethered to an outlet to get it. Even though you’ll be restricted by a power cable most of the time, notebooks such as the Qosmio X305-Q725 are much more portable than any desktop system.
The system also includes a Blu-ray drive with supporting HDMI-CEC port, Harmon Kardon premium speakers and Dolby Home Theater. The choice of storage to include with the X500 is unusual, but welcomed. You not only get a 320GB 7200rpm hard drive, but a 64GB SSD drive included as well giving you a choice between speed and capacity.
Toshiba has thought about the keyboard and mouse too and has included an LED backlit keyboard, numeric pad, and touchpad. The touchpad has multitouch for gesture input such as pinching. The casing is Omega Black with red chrome.
