[PIC]:
I have built an 8 x 128 leds designs as a matrix display,
the rows [8] goes to rb0  to rb7 then the columns goes to the ra0 to ra3
through a cascade demultiplexer.
The characters sent to the display with a scanning system,
the display just run well, BUT the light (emission) become
very dim. The message comes out of the display can only
be seen in the very shadow room.

Any one please let me know how to overcome the problem.

thank you in advance.
