lcd

There isn't enough detail in your question to provide a useful answer.

You need to tell us more about what you're trying to do (you're using a sed1330, fine, but *how*?) and what exact problems you're seeing.

I've got a project where I used an ancient (1985) Epson LCD display which used some kind or another of SED chips. They were basically shift registers; I'd shift in two rows of 1280 pixels, clock it into the drivers, and repeat 100 times to get 640x200.

One problem I encountered was driving VLCD with the wrong voltage so there was no display contrast and it looked like nothing happened.

But that's all I can say; the question is just too vague.

this does not parse. you seem to be saying that you have no idea what to do, at all. i can&#39;t help you there; you have to tell us what you are trying to do.

although i initated pwm,it failured.

i have no idea what pwm has to do with the sed1330. the lcds that i&#39;ve used don&#39;t do pwm, unless it was for contrast control via vlcd.

No offense, but we have to understand what you are asking for first.
