A type of flat-panel display that works by sandwiching a neon/xenon gas mixture between two sealed glass plates with parallel electrodes deposited on their surfaces. The plates are sealed so that the electrodes form right angles, creating pixels. When a voltage pulse passes between two electrodes, the gas breaks down and produces weakly ionized plasma, which emits UV radiation. The UV radiation activates color phosphors and visible light is emitted from each pixel.
Today, Plasma displays are becoming more and more popular. Compared to conventional CRT displays, plasma displays are about one-tenth the thickness–around 4”, and one-sixth the weight–under 67 pounds for a 40″ display. They use over 16 million colors and have a 160 degree-viewing angle.
Plasma displays are manufactured by companies such as Panasonic, Fujitsu, and Pioneer.
The underlying hardware or software for a system. For example, the platform might be an Intel 80486 processor running DOS Version 6.0. The platform could also be UNIX machines on an Ethernet network. The platform defines a standard around which a system can be developed. Once the platform has been defined, software developers can produce […]
- platform security
A security model that is used to protect an entire platform and secures the entire span of software or devices on that platform, removing the need to incorporate individual or multiple security measures for different programs on the system. Security at the platform level makes the security process simplified for IT and developers. However, once […]
(n.) A round magnetic plate that constitutes part of a hard disk. Hard disks typically contain up to a dozen platters. Most platters require two read/write heads, one for each side.
- playback control
Abbreviated as PBC, playback control is a way top control disc play on VCDs. Playback control allows users to interact with the disc through menus.
- plenum cable
Cable that is run in the plenum spaces of buildings. In building construction, the plenum (pronounced PLEH-nuhm) is the space that is used for air circulation in heating and air conditioning systems, typically between the structural ceiling and the suspended ceiling or under a raised floor. The plenum space is typically used to house the […]
