What is LED electronic display

LED electronic display is by tens of thousands of - hundreds of thousands of a semiconductor emitting diode pixel of uniform arrangement. Use different materials can be made of different colors LED pixel. At present the most widely is red, green, yellow. And blue and pure green LED development has reached practical stage.

The LED display can show that changes digital, text, image; Not only can be used in indoor environment also can be used in outdoor environment, with a projector, TV wall, LCD display screen and incomparable advantages.

LED by extensive attention and the rapid development, is with its advantages of itself inseparable. These advantages summarized up is:

High brightness, working voltage, low consumption, miniaturization, long service life, impact resistance and stable performance. LED development prospect, is currently towards a higher brightness, higher resistance to climate sex, higher luminous density, high luminous uniformity, reliability, full-color change direction.

The classification of the LED display

1, color-coded gezer can be divided into:

The single color display: a single color (red or green).

Double colors screen: red and green double colors, 256 level gray, can show 65536 colours.

Full color displays: red, green, blue three colors, 256 levels greyscale full color displays can display the 160 million colours.

2, according to display device classification:

LED digital display: display device for 7 bit code digital tube, suitable for making clock screen, interest rates, and so on screen, display digital electronic display screen.

Pictures of LED dot matrix display device screen: by many uniform arrangement is composed of light emitting diode matrix display module, suitable for broadcast text, image information.

3, according to applicable occasions classification:

Indoor display: shine some smaller, general Φ 3mm - Φ 8mm, display area is general several to ten square meters.

Outdoor screen: area is general dozens of square meters to several hundred square meters, high brightness, can work under the sun, with wind, rainproof, waterproof function.

4, according to shine some diameter classification:

Φ 3mm, indoor screen: Φ 3.75 mm, Φ 5mm,

Outdoor screen Φ 10mm, Φ 12mm, Φ 16mm, Φ, 19mm Φ 21mm, Φ, 26mm

The basic unit of the outdoor led screen shine for led cone, the principle of luminous tube is a group of red, green and blue leds packet in a plastic tube enhanced brightness shine together in.
