I don't like this design , the LEDs will be damaged pretty soon when we can't control the current passed them.

And what. Most cheap electronics gadgets have a lifetime of 1 to 3 years.
The current is controlled:
-Internal LED resistance
-2X MOSFET junctions (drive and sink)
-8 phase multiplex
-Low voltage for instance 3.0 volts
