A plasma display panel is a type of flat-panel display that uses small cells containing plasma: ionized gas that responds to electric fields. Plasma televisions were the first large (over 32 inches/81 cm diagonal) flat-panel displays to be released to the public. Until about 2007, plasma displays were commonly used in large televisions.
Plasma is the name of a VGA graphics demo created by Bret Mulvey in 1988 and released on CompuServe. It uses a diamond-square algorithm to generate a 2D pattern, and then cycles the colors using hardware palette in its 256-color mode. Plasma was picked up by demo coders for their demos where the effect was heavily used, especially in the early ...
A thin metal film (for example gold) is positioned close enough to the prism wall so that an evanescent wave can interact with the plasma waves on the surface and hence excite the plasmons. [8] In the Kretschmann configuration (also known as Kretschmann–Raether configuration), the metal film is evaporated onto the glass block. The light again ...
For the majority of images it will consume 60–80% of the power of an LCD. OLED displays use 40% of the power of an LCD displaying an image that is primarily black as they lack the need for a backlight, [35] while OLED can use more than three times as much power to display a mostly white image compared to an LCD.

An edge-localized mode (ELM) is a plasma instability occurring in the edge region of a tokamak plasma due to periodic relaxations of the edge transport barrier in high-confinement mode. Each ELM burst is associated with expulsion of particles and energy from the confined plasma into the scrape-off layer.
The term cold plasma has been recently used as a convenient descriptor to distinguish the one-atmosphere, near room temperature plasma discharges from other plasmas, operating at hundreds or thousands of degrees above ambient (see Plasma (physics) § Temperature. Within the context of food processing the term "cold" can potentially engender ...
The plasma pencil is a dielectric tube where two disk-shaped electrodes of about the same diameter as the tube are inserted, and are separated by a small gap. Each of the two electrodes is made of a thin copper ring attached to the surface of a centrally perforated dielectric disk.
Two other effects which occurred between reionization and our observations of the cosmic microwave background, and which appear to cause anisotropies, are the Sunyaev–Zeldovich effect, where a cloud of high-energy electrons scatters the radiation, transferring some of its energy to the CMB photons, and the Sachs–Wolfe effect, which causes ...
