Hello,
We are a french company that manufactues weighing systems.

We actualy using one of your display (64128M-COG-FA-BC).
We received a lot of remarques from our customers because the display is not very readable.

Do you have an other reference with same pin out and wich can be use with the same microprocessor?

We would like to satify our costumer but we don't whant to change all the pcb.
Do you have some references to advise us?
Thank you for your reply.

Hello Vincent,

Thank you for your note! I suspect this is a contrast issue and you can find example schematics here:

If you are still having issues with readability it may also be a lighting issue. This is a COG display and you are not using a backlight which means you need a fair amount of natural light. You may consider using the 64128M FC BW-3 (white backlight) if the issue persists.

Hello Jeremy,

This product have a LED Backlight so we have to make some modifications of the structure of our product.

Is it possible to have a display with different color? Before we had a green screen is it still possible to have this color?

Hi Vincent, 

 

The "A" version is no longer an active SKU. You should be able to use the schematic I sent and take the BL circuitry out. 

Best, 

Jeremy
