LED electronic display screen is composed of tens of thousands to hundreds of thousands of semiconductor light-emitting diode pixels evenly arranged. LED pixels with different colors can be made from different materials. At present, the most widely used are red, green and yellow. The development of blue and pure green LED has reached the practical stage.

at present, the most widely used are red, green, green, and so on Yellow.
and the development of blue and pure green LED has reached the practical stage.


LED panel: LED is the abbreviation of light emitting diode, short for LED.
it is a display mode by controlling semiconductor LED.
it is used to display text, graphics, images, animation, market, video, etc The display screen of video signals and other information.


LED display screen is divided into graphic display screen and video display screen.
both are composed of LED matrix blocks.
Graphic display screen can display Chinese characters, English text and graphics synchronously with computer; The video display screen is controlled by microcomputer.
it can display all kinds of information in a real-time, synchronous and clear way of information transmission. It can also display two-dimensional and three-dimensional animation, video, TV, VCD programs and live scenes.
the LED display screen shows bright colors.
it has a strong sense of three-dimensional, static as oil painting and dynamic as film. It is widely used in stations, docks, airports and other areas Shopping malls, hospitals, hotels, banks, securities markets, construction markets, auction houses, industrial enterprise management and other public places; It can be used not only in indoor environment, but also in outdoor environment.
it has the incomparable advantages of projector, TV wall and LCD.

LED has been widely valued and developed rapidlyThese advantages can be summarized as follows: high brightness, low operating voltage, low power consumption, miniaturization, long service life, shock resistance and stable performance.
LED has a very broad development prospect.
at present, it is moving towards higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, higher reliability, high reliability, high reliability and high reliability Full color development.
classification of LED display screen 1. According to color primary color, it can be divided into single primary color display screen: single color (red or green).
dual primary color display screen: red and green dual primary color.
256 gray level, which can display 65536 colors.
full color display screen: red, green, red, green Blue three primary colors.
256 gray level full-color display screen can display more than 16 million colors.
2. Classified by display device, LED digital display screen: display device is 7-segment code nixie tube.
suitable for making clock screen, interest rate screen, etc, Electronic display screen for displaying numbers.
LED dot matrix graphic display screen: the display device is a dot matrix display module composed of many evenly arranged light-emitting diodes.
it is suitable for playing text and image information.
3. Indoor display screen according to the application situation: the light-emitting point is small.
generally Φ 3mm-- Φ 8 mm, the display area is generally several to more than ten square meters.

outdoor display screen: the area is generally tens of square meters to hundreds of square meters.
high brightness, can work in the sun, with wind, rain, waterproof functions.
4 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 tubeThe principle of the light-emitting tube is to seal a group of red, green and blue light-emitting diodes in a plastic tube to emit light together,
