1, LED is the abbreviation of "Light Emitting Diode", translated as "light emitting diode". It's kind ofAn electronic device that converts electrical energy into light. Compared with traditional fluorescent lamps, leds have the advantages of higher energy efficiency, longer life, smaller volume and higher color reproduction.
2, LED is the abbreviation of Light-EmittingDiode, Chinese translation is light-emitting diode. It is a semiconductor device that can convert electrical energy into light energy, thus achieving the function of light.
3, the led chip is the light-emitting diode chip, that is, the lighting chip you say. It's essentially a pn node, with electrons and holes in the depletion layer of the pn nodeCompound, after the compound, the extra energy is emitted in the form of photons, that is, the light is illuminated.
4, LED called light emitting diode, is a kind of light emitting diode, that is, a kind of diode. And a diode is just one kind of semiconductor. So in terms of the noun range: semiconductor diode LED.
5, LED Light emitting Diode (LightEmitting Diode, LED), is a semiconductor component. At first, it is used as an indicator light, display LED board, etc. With the emergence of white leds, they are also used as lighting
1, LED is essentially a semiconductor device, its luminous principle is the use of semiconductor materials and external electric field interaction and electroluminescence. The doping technology of semiconductor materials is the basis of manufacturing LED, and doping different materials can produce different colors of light. Therefore, semiconductor technology is one of the core technologies of LED manufacturing.
2, LED called light emitting diode, is a kind of light emitting diode, that is, a kind of diode. And a diode is just one kind of semiconductor. So in terms of the noun range: semiconductor diode LED.
3, LEDIs the abbreviation of English Light Emitting Diode (light emitting diode), is a semiconductor solid light emitting device. Using solid semiconductor chip as luminous material, excess energy is released through carrier recombination in semiconductor, which causes photon emission, and directly emits red, orange, yellow, green, blue, purple and white light.
4, LED (Light Emitting Diode), that is, light emitting diode, is a semiconductor solid light emitting device, which uses a solid semiconductor chip as a light-emitting material, when both ends are plus a forward voltage, semiconductingThe carrier recombination in the body causes photon emission and produces light.
LED chips are composed of arsenic, aluminum, gallium, indium, phosphorus and nitrogen, and are divided into general brightness, high brightness, ultra-high brightness, and even infrared and photoelectric components according to the brightness and composition of the elements. From binary to four-element wafers, each category has its own unique performance and application areas.
LED chip classification: according to the composition can be divided into: binary, ternary, four-element LED chip. so-calledBinary, ternary, four-element LED chip refers to the number of effective elements contained in the chip.
According to the shape classification, the chip is generally divided into round and square pieces. Among them, the wafer is relatively low grade, the performance is not stable enough, generally do not use the led produced by the wafer; Squares are generally measured in size, such as 12 mil (1 mil =0.0254 square mm).
Abstract: What are the types of LED display driver chips? LED driver chips can be divided into general chip and special chip two. The so-called universal chip, the chip itself is not specifically designed for LEDInstead, some logic chips with some logic functions of the LED display (such as series-parallel shift registers).
LED chips are mainly sapphire substrate, silicon substrate and silicon carbide substrate three kinds of sapphire substrate: the market share ranks first, is from the Japanese company's patented technology.
is usually manufactured on the surface of a semiconductor wafer. A semiconductor is a material that conducts electricity between a conductor and an insulator at room temperature. Semiconductors are widely used in consumer electronics and telecommunicationsInformation systems, medical instruments and other fields.
Chip is the general term for semiconductor component products. It is an integrated circuit (IC, complete circuit) carrier, which is divided by a chip. A silicon wafer is a small piece of silicon that contains an integrated circuit and is part of a computer or other electronic device. A semiconductor (semiconductor) is a material whose electrical conductivity at room temperature is between that of a conductor and an insulator.
chip (chip) is a general term for semiconductor component products, in electronics is a way to miniaturize circuits (mainly including semiconductor devices, but also including passive components, etc.), and is often manufactured on the surface of semiconductor wafers.
Concept: Semiconductor refers to materials with conductive properties between conductors and insulators at room temperature, such as silicon, germanium, etc. A chip, on the other hand, is a way of miniaturizing a circuit in electronics, usually made on the surface of a semiconductor wafer. Category: A semiconductor is a material that can be used to make electronic components.
