Winstar's graphic LCD 128*64

[Mahyar-jafari]

Hi guys,
I want to use Winstar's graphic LCD in an industrial project ,Performance and reliability are more important to me than graphics .Has anyone worked with it?

Is it reliable?

Has anyone found any problems with using it?

Or  it is better to use tft or something else ?

Take care on the lifetime of the backlight....
 beside this those we used were fine and stable (320x240, 3,5", b/w, without controller) not aviable anymore.

I have used their character parts, but in low volume. So far had
good results. My focus was display brightness, uniformity, and
contrast.

Regards, Dana.

I have another question, i want to drive graphic lcd 128*64 with stm32f4 micro,it seems for me for long life operation and reliability use buffer  to isolate I/o pins from lcd ?

Is it necessary? Or its better to connect directly ?

What do you suggest? Which buffer model is better to use?

depends on your market... for a single piece I won`t do anything which makes it more complicated.

But if you need some kind of EMC-tests and your stuff should survive industrial or HBM-ESD... add a  buffer. Which buffer you must decide by yourself, choose that one which fits best for you..
