Graphic LCDs / Re: NHD-C12864A1Z-FS(RGB)-FBW-HT1 contrast setting
« on: April 28, 2015, 07:57:20 AM »
Hello Rob,

Thanks for reaching out. NHD-C12864A1Z-FS(RGB)-FBW-HT1 contrast can be controlled via software using the Electronic Volume Commands and V5 Voltage Regulator Internal Resistor Ratio Set. Please refer to page 37 - 38 in the displays controller datasheet.

Hope this helps!

Hello,

I recommend double checking your initialization, please use our example initialization sequence in the display's datasheet, page 8.

If possible can you please provide your code, thanks!

Hello,

Thank you for the additional information. Your display appears to be hooked up correctly which is good! The fading could have been caused due to exposure of moisture.

The steam radiator heating system or having the unit placed closely to leaky doors / windows could slowly cause fading of the pixels. I recommend trying to seal the enclosure a little better just as a precaution.

Hope this helps!

Hello,

This is not typical behavior, can you please tell me how you are driving the display?

Can you also list what kind of environment this display is in?

Thanks!

No problem, I am updating the datasheet as we speak.

Have a good one!

Hello,

We have verified the correct configuration for 5V operation, please see the table attached. The updated spec will be available later today, I apologize for the inconvenience.

Thanks.

Hello,

I'm sorry, unfortunately we can not give you an exact response time without physically testing the display under those conditions.

You are correct that the response time will drop in very cold temperatures, but by how much? You will need to conduct some testing  8)

Hello Sugumar,

Question 1:
"What is the back-light supply voltage tolerance for the LCD part: NHD-0420AZ-FL-GBW-33V3?"

Answer:
Typ: 3.0V   |   Max: 3.3V (With a current limiting resistor)


Question 2:
"What is the minimum LCD supply voltage for the same LCD part?"

Answer: 3.0V

Hello,

Page four in the displays datasheet does not list power and GND tied together. The upside-down triangle represents ground and the right-side up triangle represents power.

NHD-320240WX-COTFH-V#I041 is a 3.3V module and the logic is 3.3V, you should not connect 5V to this display.

 e.g. When connecting NHD-320240WX-COTFH-V#I041 to an Arduino Board (which is 5V logic), this will require level shifting for the I/O pins.

Hello,

To answer your question yes, however please use a current limiting resistor  8)

Hello,

Thank you for reaching out. NHD-320240WX-COTFH-V#I041 is a 3.3V module not 5V. We will work with Jameco to have the part description corrected on their website.

In the mean time please review the datasheet for NHD-320240WX-COTFH-V#I041:

http://www.newhavendisplay.com/specs/NHD-320240WX-CoTFH-VI041.pdf

Regarding SEL1, by default the LCD is set up for 8080, if you move the jumper down one pad it will be configured for 6800.

Hope this helps!
