Light emitting diodes can also be divided into ordinary monochrome light emitting diodes, high brightness light emitting diodes, ultra-high brightness light emitting diodes, color changing light emitting diodes, flashing light emitting diodes, voltage controlled light emitting diodes, infrared light emitting diodes and negative resistance light emitting diodes. LED control modes are constant current and constant […]
Light-emitting diodes, referred to as LEDs, are made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), and others. When the electron and hole complex can radiate visible light, so it can be used to make light-emitting diodes. They are used as indicator lights in circuits and instruments, or to form text or […]
History of Semiconductor Development The discovery of semiconductors can actually be traced back a long time. In 1833, British scientist Faraday, the father of electronics, was the first to discover that the resistance of silver sulfide changes with temperature differently from that of ordinary metals, in general, the resistance of metals increases with temperature, but […]
