What is the LED display and LED electronic display

From: Data:30/08/2016


, that is, emitting diode light, is the light emitting diode. LED display is a display control semiconductor light emitting diode through, its general appearance is by many a red light is usually composed, extinguishes brightly depending on the light to show the characters. LED

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

LED display can display the change in the numbers, text, graphics and image; not only can used for indoor environment can also be used in outdoor environment, with projectors, LCD TV wall, and the incomparable advantages. LED

has received extensive attention and has been developed rapidly, and it has the advantages of its own. These advantages are summarized as:

high brightness, low operating voltage, low power consumption, small size, long life, impact resistance and stable performance. Led the development prospect is extremely broad, is currently towards a higher brightness, higher resistance to climate, and higher luminous density, higher luminous uniformity, reliability, full color in the direction of development. Classification

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

double color display: red and green dual color, gray level 256, can display 65536 colors.

full color display: three primary colors of red, green and blue, 256 level grayscale full-color screen can display more than 16 million kinds of colors.

2, according to the display device category: LED

digital display: display device for the 7 segment code digital tube, suitable for the production of Shi Zhongping, the interest rate screen, display digital electronic display. LED

dot matrix graphic display: display device is composed of a number of evenly arranged LED dot matrix display module, suitable for playing text, image information.

3, according to the use of occasions classification:

indoor display: light point is smaller, generally Φ 3mm--Φ 8mm, display area in general a few to ten square meters.

outdoor display the general area of dozens of square meters to several hundred square meters, high brightness, can work in the sun, wind, rain, waterproof function. (Hefei LED luminous characters

4, according to the luminous point diameter of classification:

indoor screen: Φ 3mm, Φ 3.75 mm, &Phi. 5mm,

for luminous tube, light-emitting tube principle is will be a group of red, green and blue light emitting diode sealed in a plastic tube co luminescence brightness enhancement.
