What is led electronic screen?
What is led electronic screen?The abbreviation of LED light emitting diode (LED).
it is widely used in daily life.
for example, the indicator light of home appliances, automobile rear fog light, etc.

What is led electronic screen? how much?

the most significant feature of LED is its long service life.
high photoelectric conversion efficiency.
LED modules are arranged in matrix or pen segment.
prefabricated into standard size modules.
the commonly used ones are 8x8 lattice modules (64 in monochrome) × One or two primary colors have 64 × Two light-emitting diodes).
8-word seven segment digital moduleIn order to improve the brightness.
to increase the line of sight, more than two to dozens of LEDs are integrated and packaged into a cluster tube as a pixel
this kind of LED bundle tube is mainly used for making outdoor screen.
also known as pixel tube.
this kind of LED bundle tube is mainly used for making outdoor screenThe LED display panel assembles and arranges the LED modules or cluster tubes into a matrix according to the actual size.
it is equipped with a special display circuit and DC voltage stabilizedSource, software, frame and external decoration constitute a LED displayLED electronic display screen is composed of tens of thousands to hundreds of thousands of semiconductor light-emitting diode pixels evenly arranged.
different materials can be used to make LED pixels with different colors.
at present, red, green and yellow are the most widely used ones.
the development of blue and pure green LEDs has reached the practical stage.
the development of LED electronic display screen has reached the practical stageThe LED display screen is divided into graphic display screen and video display screen.
both are composed of LED matrix blocks.
the graphic display screen can be displayed synchronously with the computerWords, English text and graphics; The video display screen is controlled by microcomputerGraphics and images, real-time, synchronous, clearIt can also display 2D, 3D animation, video, TV, VCD programs and live scenes.
LED displayThe screen display has bright colors.
it has a strong sense of three-dimensional, static as oil painting and dynamic as film, and is widely used in stations, docks, airports, shopping malls, hospitals, etcHotels, banks, securities markets, construction markets, auction houses, industrial enterprise management and other public places.
LED display can display changing numbers, text, graphics and images; It can be used not only in indoor environment but also in outdoor environment.
it has incomparable advantages over projector, TV wall and LCD screen.
it can be used in outdoor environmentLED has been widely valued and developed rapidly.
it is inseparable from its own advantages.
these advantages are summarized as followsThe development prospect of LED is very broad.
at present, LED is developing in the direction of higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability and panchromatic.
LED has the advantages of high brightness, low working voltage, low power consumption, miniaturization, long service life, impact resistance and stable performanceClassification of LED display1. According to the basic color, it can be divided intoSingle primary color display screen: single color (red or green).
the color of display screen is red or greenDual primary color display screen: red and green dual primary color.
256 gray levels, 65536 colors can be displayed.
the dual primary color display screen can display 65536 colorsFull color display: red, green and blue.
the full color display with 256 gray levels can display more than 16 million colors. it is suitable for playing text and image information.
the LED dot matrix graphic display screen is composed of a number of evenly arranged light-emitting diodes3. Classification according to usageIndoor display: small light spot.
general Φ 3mm-- Φ The display area is generally several to ten square metersOutdoor display screen: the area is generally tens of square meters to hundreds of square meters.
it has high brightness, can work in the sun, and has the functions of windproof, rainproof and waterproof4. Classification according to the diameter of luminous pointIndoor screen: Φ 3mm、 Φ 3.75mm、 Φ 5mm、Outdoor screen: Φ 10mm、 Φ 12mm、 Φ 16mm、 Φ 19mm、 Φ 21mm、 Φ The basic unit of 26mm outdoor screen is light-emitting tube.
the principle of light-emitting tube is to seal a group of red, green and blue light-emitting diodes in a plastic tube to emit light togetherWhat is led? What is led electronic screen? Classification of LED electronic screen
