Led matrix brightness problem

Other Hardware LEDs and Multiplexing

Thanks PaulRB for your help and time.

PaulRB:
It is possible to light up to 4 LEDs at any instant.

But i need to light up only an led when i give row and column. not 4 leds.

also i changed 330ohms to 120Ohms resistors (increased 25% brightness of leds) at columns side.

Thanks again.
