I am using HT1632C in one of my company project. I am using 8 holtek IC driven by its internal RC osc. Their is no problem in fixed display strings. But in case of scrolling display the characters are getting double width and uneven flickering is observed in the edges. Please give me the idea why it is so. My 16X16 led matrix module is arranged like
COM7
COM6
COM5
COM4
COM3
COM2
COM1
COM0
ROW1 ROW3 ROW5 ROW7 ROW9.........31

I am helpless to get a flicker free scroll display. By the way Please note that I have used Mosfet IRLML6346TRPBF in every COMMON line. I am using P-MOS open drain output and
8 COM option. I have used ROWS in place of columns of my display.
