Diode

Technology / Programming / Diode: The diode acts like a one-way valve for current, and this is a very useful characteristic. One application is to convert alternating current (ac), which changes polarity periodically, into direct current (dc), which always has the same polarity.

Light-Emitting Diode (LED)

Technology / Computers / Light-Emitting Diode (LED): Abbreviation of light emitting diode, an electronic device that lights up when electricity is passed through it. LEDs are usually red. They are good for displaying images because they can be relativel MORE

LED

Entertainment / Photography / LED: Light emitting diode. Led is an indicator light used to convey exposure information. MORE

Lcd

Technology / Home Audio / Lcd: Liquid Crystal Display. Probably the most common way of showing visual information on non-computer electronic equipment. MORE

Gallium (Ga)

Science / Periodic Table of Elements / Gallium (Ga): Atomic number: 31, Atomic mass: 69.72 g.mol -1, Electronegativity: unknown, Density: 5.1 g.cm-3 at 20°C, Melting point: 29.8 °C, Boiling point: 2204 °C, Vanderwaals radius: 0.161 nm, Ionic radius: MORE

Anode

Science / Chemistry / Anode: The electrode at which oxidation occurs in a cell. Anions migrate to the anode. MORE

Active Matrix

Technology / Computers / Active Matrix: A type of LCD (liquid crystal display) structure that is actively controlled by a diode or transistor. This allows for each pixel to be independently controlled which produces excellent color resoluti MORE
