LED 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.

Working principle of LED display

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


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 the incomparable advantages of projector, TV wall and LCD.


LED has been widely valued and developed rapidly.
it is inseparable from its own advantages.
these advantages can be summarized as follows: high brightness, low working voltage, low power consumption, miniaturization, long service life, low power consumption, low power consumption, low power consumption, low power consumption, low power consumption and so on The 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.


classification of LED displays

1 According to the color base 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 colors.
256 gray level, 65536 colors can be displayed.


full color display screen: red, green and 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: the display device is a 7-segment code nixie tube.
LED digital displayIt is suitable for making clock screen, interest rate screen, etc., and displaying digital electronic display screen.


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 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.
it has high brightness, can work in the sun, and has the functions of windproof, rainproof and waterproof.


4 Φ 3mm、 Φ 3.75mm、 Φ 5mm,

outdoor screen: Φ 10mm、 Φ 12mm、 Φ 16mm、 Φ 19mm、 Φ 21mm、 Φ 26mm

The basic unit of outdoor screen light-emitting is light-emitting tube.
the principle of light-emitting tube is that a group of red, green and blue light-emitting diodes are sealed in a plastic tube to emit light together and enhance brightness.
