Hello,
I am using CFAL12864C display and running into this issue where it almost seems like turning some pixels on or off affects the contrast level of other pixels. Has anyone run into this?
On my display I see these horizontal lines which are less brighter than the rest of the display. I also have a block of size 24 pixels by 3 pixels that is blinking( On for 700msec and off for 300 msec). When it is off it seems to dim the whole line (128 pixels by 3 pixels).
Anybody has any idea why would something like this happen? I have played around different values of pre-charge periods, clock divider and the oscillator frequency but nothing seem to make a difference.
Thanks in advance,
Ananda
