A light emitting diode is disclosed, comprising a semiconductor body (1), wherein the semiconductor body (1) comprises an active region (11) provided for producing radiation, a carrier body (2), which is fastened to the semiconductor body (1) on an upper side (1a) of the semiconductor ...
To understand how a light-emitting diode works, you need to get into the physics part of semiconductors. Simply explained, the LED is similar to astandard diode, but with the addition of a phenomenon calledElectroluminescence. The LED is made of electroluminescent materials, such as gallium arsen...
C A light emitting diode (发光二极管), or L.E.D., is a device that shines when electricity passes through it.But it works differently than traditional kinds of light bulbs.Light emitting diodes use less energy and last much lo
解析 A。“LED”是“Light Emitting Diode”的缩写,意为发光二极管。“LCD”是“Liquid Crystal Display”(液晶显示器);“OLED”是“Organic Light Emitting Diode”(有机发光二极管);“QLED”是“Quantum Dot Light Emitting Diode”(量子点发光二极管)。所以答案是 A。
Light-Emitting Diode (LED): Function: Converts electrical energy into light energy when forward biased. Operation: When a forward voltage is applied across the LED, it allows current to flow, causing electrons to recombine with electron holes in the semiconductor material, emitting photons (light)...
