The alkaline earth metals are six chemical elements in group 2 of the periodic table.
Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction.
An amateur radio operator is someone who uses equipment at an amateur radio station to engage in two-way personal communications with other amateur operators on radio frequencies assigned to the amateur radio service.
An anode is an electrode through which the conventional current enters into a polarized electrical device.
Cadmium is a chemical element with symbol Cd and atomic number 48.
The candela per square metre (cd/m2) is the derived SI unit of luminance.
The cathode ray tube (CRT) is a vacuum tube that contains one or more electron guns and a phosphorescent screen, and is used to display images.
Cathodoluminescence is an optical and electromagnetic phenomenon in which electrons impacting on a luminescent material such as a phosphor, cause the emission of photons which may have wavelengths in the visible spectrum.
A color gel or color filter (British spelling: colour gel or colour filter), also known as lighting gel or simply gel, is a transparent colored material that is used in theater, event production, photography, videography and cinematography to color light and for color correction.
Colorfulness, chroma and saturation are attributes of perceived color relating to chromatic intensity.
A dashboard (also called dash, instrument panel (IP), or fascia) is a control panel located directly ahead of a vehicle's driver, displaying instrumentation and controls for the vehicle's operation.
Diffusion is the net movement of molecules or atoms from a region of high concentration (or high chemical potential) to a region of low concentration (or low chemical potential) as a result of random motion of the molecules or atoms.
A display device is an output device for presentation of information in visual or tactile form (the latter used for example in tactile electronic displays for blind people).
The electron is a subatomic particle, symbol or, whose electric charge is negative one elementary charge.
An electronic game is a game that employs electronics to create an interactive system with which a player can play.
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation.
A Fresnel lens is a type of compact lens originally developed by French physicist Augustin-Jean Fresnel for lighthouses.
Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics.
Handheld electronic game(s) are very small, portable devices for playing interactive electronic games, often miniaturized versions of video games.
In vacuum tubes and gas-filled tubes, a hot cathode or thermionic cathode is a cathode electrode which is heated to make it emit electrons due to thermionic emission.
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated to such a high temperature that it glows with visible light (incandescence).
, founded as Keio Electronic Laboratories, is a Japanese multinational corporation that manufactures electronic musical instruments, audio processors and guitar pedals, recording equipment, and electronic tuners.
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals.
A microprocessor is a computer processor that incorporates the functions of a central processing unit on a single integrated circuit (IC), or at most a few integrated circuits.
A microwave oven (also commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range.
Multiplexed displays are electronic display devices where the entire display is not driven at one time.
A Nixie tube, or cold cathode display, is an electronic device for displaying numerals or other information using glow discharge.
An organic light-emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current.
An oxide is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula.
Persistence of vision refers to the optical illusion that occurs when visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye.
A phosphor, most generally, is a substance that exhibits the phenomenon of luminescence.
The Restriction of Hazardous Substances Directive 2002/95/EC, (RoHS 1), short for Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment, was adopted in February 2003 by the European Union.
A seven-segment display (SSD), or seven-segment indicator, is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.
A sixteen-segment display (SISD) is a type of display based on 16 segments that can be turned on or off according to the graphic pattern to be produced.
