What Is Led Digital Light Tube?

led digital tube, as the name suggests, is an electronic display using led as a display element. LED (Light Emitting Diode) light emitting diode, is a solid semiconductor device that can convert electrical energy into visible light, which can directly convert electricity into light. Due to the inherent characteristics of the LED itself, that is, one-way conductivity and current limiting characteristics, it is very suitable for use as a light source.

LED digital tube by red (R), green (G), blue (B) three colors composed of three primary color lights to form a pixel unit display.

1. Red: When the red signal is input, a high level voltage Uf is generated in the circuit; When the voltage is increased to a certain threshold, the output low level; When this voltage is applied again the output high potential; This cycle is repeated until a stable state is reached.

2, green: When the green signal is input, a low-level pulse signal Egh is generated in the circuit; After the pulse is amplified, a high level pulse UfH is obtained. After amplification, output low level Egh,

3, blue: blue signal input generates a low voltage pulse Egn,

4. Through the above process, the three basic units are arranged in a certain way to form a variety of patterns, words and symbols of different shapes.

5, the use of scanning technology to control each basic unit can achieve a variety of changes such as water, flicker, gradual alternating effect, etc.

6, the use of the driver chip to control the basic unit can achieve a variety of dynamic effects such as rotation, movement, scaling and other effects,

7, can directly use the computer software design program to generate the required dynamic screen,

8, can be directly programmed with computer software to achieve the connection with external equipment,

9, with brightness adjustment function;

10, with automatic protection function;

11, with constant current driving function;

12, with fault self-test and alarm prompt function;

13, with remote data transmission function;

14, suitable for any kind of display;
