A LED display sending card and receiving card quantity calculation
Example: Now the customer has customized a P10 indoor full color display, requiring a length of 20 meters and a height of 10 meters. Calculate how many modules to use. P10 display unit board size is: 32cm * 16cm. Length using module number: 2000cm/32cm=62.5 Width using modules 1000cm/16cm = 62.5 2, calculate the length and […]
What is LED working Principle
The working principle of LED (Light Emitting Diode) is based on a phenomenon known as electroluminescence. Electroluminescence is the process by which light is emitted from a material when an electric current is passed through it. LEDs are made from a semiconductor material, typically a compound called gallium arsenide (GaAs) or gallium phosphide (GaP). These […]
