The concept of LED
LED is the abbreviation for light emitting diode. LEDs are arrayed breadthwise and lengthways with a stable pitch that forms LED matric-LED Display Screen. Each LED of the LED Display has a corresponding luminance control circuit. The computer controls the circuit, the circuit influences the brightness of each LED, then the pictures and text we need are formed.

Advantages of LED Display
1) High Definition and can be adjusted, able to show DVD, TV, Dynamic images, VCRs, graphs, letters and animations for 24 hours, synchronized with the computer monitor.
2) With the features of waterproof, sunscreen, anti-static, damp proof, anti-freeze, anti-thundering.
3) With excellent equality and consistency of light, able to solve the problem of mosaic commendably.
4) With clear, exquisite and real display effect.
5) With big viewing angle to the horizontal line and vertical line, able to be watched at every angle, no picture change, no color excursion.
6) The cost of maintenance is low, as each LED lamp can be replaced.
