Hello Michael!

I highly recommend you check out CadSoft's community library repository. This is where Eagle users can upload files to share with other EAGLE users.

Hope this helps!

Hi Parsec!

I highly recommend you check out this link  ;)

Please note the following write up uses the SEPS525 controller (same as our 1.69" Color OLED: NHD-1.69-160128UGC3). You will need to modify the initialization sequence and other various parameters if you would like to use NHD-1.5-128128UGC3.

Hope this helps!

To answer your second question, yes resistive touch screens work with gloved hands  8)

The resistive touchscreen is the most common type of touchscreen. Except for modern smartphones, tablets and trackpads, most touchscreens we come in contact with are actually resistive touchscreens. As youíve probably guessed, the resistive touchscreen relies on resistance. In that respect, itís pretty intuitive to understand Ė the pressure you apply causes the screen to respond.

Hope this helps!

Hi mnauss,

NHD-12864WG-BTMI-V#N and NHD-12864WG-BTFH-V#N-ND are both transmissive displays meaning all of the light is provided from the backlight of the LCD Panel.

A transmissive LCD looks great in indoor environments, but can be quite dim when in direct sunlight.

I highly recommend you use NHD-12864WG-BTFH-V#N

NHD-12864WG-BTFH-V#N is a transflective LCD, which is a combination of a transmissive and reflective LCD.

Feel free to contact me if you have any questions or concerns. :D

In a Liquid Crystal Display (LCD), V0 is used to vary the screen brightness or contrast. Contrast, simply put is the ratio of the light areas to the dark areas in a LCD.

Hello Gregory,

I recommend using a 10K potentiometer  ;)

This will let you adjust the contrast. Each LCD will have slightly different contrast settings so adjust accordingly and always consult with the displays datasheet.

Hope this helps!

Hi Fred,

Thank you for sharing!  :)

Sorry for the confusion, however I can assure you that the Supply Voltage (VDD) for NHD-0420DZW-AY5 is 3.0 (Min.) - 5.0 (Typ.) - 5.3 (Max.).

The prefix "5" in the part number represents the displays typical voltage.

Have a good one!  ;)

To answer your question the Supply Voltage (VDD) for NHD-0420DZW-AY5 can be anywhere from 3.0 (Min.) - 5.0 (Typ.) - 5.3 (Max.).

This can be viewed on page 6 in the displays datasheet:

Hope this helps!

Hi Jim,

Sounds like a fun project!

The timing values listed above are perfectly acceptable, I would like to see your boot process if possible.

To see the actual boot process a RS232 cable like the TTL-232R-3V3 from FTDI is needed. Just plug it into the J1 connector and open a serial terminal of your choice.

Finally, post the terminal output on the forum so we can start debuging  8)

Hi Jesse!

Great question, when a display has a Hot-bar connector the flex needs to be soldered directly to the pcb. You will not be able to locate any standard FFC connectors to accommodate this.

There are a lot of benefits for using a direct flex-to-board connection. It saves vertical height, can be more reliable than fine pitch connectors and saves the cost of the connectors.

Morning Zafi,

I recommend using NHD-1.8-128160EF-CTXI#-FT:

Please note this particular display is Non-Stocked and requires a MOQ of 3000 pc.

The MOQ maybe an issue in your case, it might be worth taking a look at our 2.4" Resistive Touch TFT's with a standard FFC ZIF connector (In-Stock):

Hope this helps!

The LCD connector on NHD-1.8-128160EF-CTXI# needs to be soldered directly to the pcb (via a Hot-bar machine).

If you are interested in a traditional FFC ZIF LCD connector I recommend using the following display:


LCD Connector: 24pin 0.5mm FFC connector. Molex P/N: 52435-2471
