Fantastic, enjoy your display!   8)

OLEDs / Re: NHD-0240CW-AR3 runs very hot with 5V supply

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

Have a good one!

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.



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?"

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

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.


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

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:

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!

Thank you for reaching out. It is common practice to ground the unused data lines. We have tested both methods in the lab and can confirm there are no differences between leaving DB0-DB3 as a NC or tied to GND.

Hope this helps!


Thank you for reaching out. It would appear that there is a slight issue with your initialization sequence / timing. I recommend double checking your code with what is listed on page 11 in the displays datasheet.

Please feel free to share you code, hope this helps!

Hello Sugumar,

Thank you for reaching out. NHD-0420H1Z-FL-GBW-33V3 was designed to be a 3.3V module, I do not recommend running it at 5.0V.

Hope this helps!

TFTs / Re: NHD-5.0-800480TF-ATXL linux driver code
« on: March 27, 2015, 08:20:26 AM »

Iím sorry, unfortunately we do not have any Linux drivers available for the TFT, except for the FocalTech CTP drivers.

I am not to familiar with the Phytec 052 SOM, does this board have a built in TFT controller? If not you will need to use an external one.  There are several TFT controllers on the market (the SSD193 being one of them) so you may use whatever you prefer.

Finally, I highly recommend checking out Phytec's wiki page, I'm sure you will find some useful information.

Hope this helps!

TPS61165 from TI is an acceptable choice. You can also use FAN5333BSX:

Both will get the job done :)

Hello Randy,

Glad to hear you got it working, enjoy your display!

« on: March 18, 2015, 07:54:55 AM »

Thanks for reaching out, NHD-C12832A1Z-FSW-FBW-3V3 is meant to be soldered directly to a pcb. We sell a 17 pin Thru-hole to 2x4 Conversion board for NHD-C12832A1Z displays. All necessary capacitors for the voltage booster-circuit and current limiting resistor are included. Please see the link below  8)

Hope this helps!
