I call simply, now the so-called LED display is only the backlight, which is led light, replacing the original ordinary light, saving energy and environmental protection, long life of the display.
] the inherent characteristics of LED decide that it is the most ideal light source to replace the traditional light source.
it has a wide range of uses.

What are the differences between LCD and LED display?

1 Small size led is basically a very small chip, which is encapsulated in epoxy resin.
so it is very small, very light.
Second, low power consumption, LED power consumption is quite low.
generally speaking, the working voltage of LED is 2-3.6v.
the working current is 0.02-0.03a.
that is to say, it consumes no more than 0.1W.
Third, the working voltage of LED is 2-3.6v It has a long service life, and the service life of LED can reach 100000 hours under the appropriate current and voltage.
4. High brightness and low heat led use cold light technology.
the calorific value is much lower than that of ordinary lighting lamps.
5. Environmental friendly LED is made of non-toxic materials.
unlike fluorescent lamps, Mercury will cause pollution, and LED can also be recycled.
6 Solid and durable LED is completely encapsulated in epoxy resin.
it is stronger than bulb and fluorescent tube.
there is no loose part in the lamp body.
these characteristics make led not easy to damage.
high energy saving: energy saving and pollution-free is environmental protection.
DC drive.
ultra low power consumption (single tube 0.03-0.06 Watt) electro-optic power conversion is close to 100%, The same lighting effect can save more than 80% energy than traditional light sourceLong life: LED light source is called long life lamp.
it means the lamp that never goes outSolid cold light source.
there is no loose part in the lamp body with epoxy resin package, and there are no defects such as filament burning, heat deposition, light decay, etc. the service life can reach 60000 to 100000 hours, which is more than 10 times longer than that of traditional light source.
the solid cold light source with epoxy resin package has no loose part in the lamp bodyChangeable Fantasy: LED light source can use the principle of red, green and blue three primary colors.
under the control of computer technology, three colors have 256 gray levels and can be mixed arbitrarily to produce 256 × two hundred and fifty-six × 256=16777216 colors, forming a variety of combinations of different light colors, realizing rich and colorful dynamic change effects and various images.
in this way, we can create a variety of imagesEnvironmental protection: the environmental protection benefit is better.
there is no ultraviolet and infrared in the spectrum, neither heat nor radiation, the glare is small, and the waste can be recycled, no pollution, no mercury element, cold light source, and can be safely touched, so it belongs to the typical green lighting light source.
there is no pollution in the spectrumHigh Tech Tip: compared with the monotonous luminous effect of traditional light source.
LED light source is a low-voltage microelectronic product, which successfully integrates computer technology, network communication technology, image processing technology, embedded control technology, etc., so it is also a digital information product. It is a "high tech tip" technology of semiconductor optoelectronic devices, with the characteristics of online programming, unlimited upgrade, and flexibilityFeatures of LCDLow voltage micro power consumptionFlat plate structurePassive display type (no glare, no eye irritation, no eye fatigue)Display a large amount of information (because pixels can be very small)Easy to color (very accurate reproduction on chromatogram)No electromagnetic radiation (for human safety and information confidentiality)Long life (this kind of device has almost no deterioration problem, so it has a very long life, but the LCD backlight has a limited life, but the backlight can be replaced).
