You need to find a data sheet describing your particular brand and model of LED display. It will show you how the pins connect to the internal LEDs, and if it has any unused pins.

Your microcontroller program needs to scan the display, by illuminating only one row (or one column) at a time. Step through all the rows (or columns) quickly so your eye doesn't notice the flickering. The web page you found also describes the process in general.
 
Thank you very much my dear for help
I found a good DataSheet for similar brand
best regards
 
Does the data sheet answer your questions? Do you need help understanding the data sheet, or implementing the LED matrix scanning technique?

The company's name is humorous.
