OLEDs / Re: NDH-0220CW: cursor not visible with text

The cursor should still be able to show up.
Would you be able to tell me what settings you have for the Display On/Off register?

What is the current limit for your backlight supply?

For the backlight you would not need to apply the Display Enable signal. Also could you give me a date code for the display you are currently using?

Graphic LCDs / Re: NHD-C12864WC-FSW-FBW-3V3-M random pixels at init

This is most likely due to the high contrast. I would recommend using a lower setting for the electronic volume.
This will determine the pixel clarity.

It seems that your contrast might be set a bit high.

The random pixels can result from any mix of information that could be stored in the RAM for the display controller.
Have you tried to clear the screen after initializing it?

TFTs / Re: NHD-2.4-240320CF-CTXI#-F spec on VDDIO

We often recommend tying the VDDIO to the VDD pin.
The 3.3V is still within the safe operating voltage for the Controller IC.

According to the Datasheet (Page 131), the VDDIO needs to be powered down before the VDD.

Because of these we have not tried to test power drain while VDD is not applied.

For 3D model requests, can you please email

Hi Joe,

You should be able to use the Screen Editor with the Shield.
You would need to select the FT801 for the Device. And under the Export drop down, select the VM801B43 option.

Some of these commands are required for our NHDev Development Board code.

I do have example Arduino code for this display, could you please email me at for the examples.

OLEDs / Re: Flickering NHD-0220CW-AY3
« on: November 16, 2016, 03:10:50 PM »
The flickering can be caused by a lack of current being supplied to the voltage boosting circuit.

Would it be possible to record a video of the flickering that occurs?

Please send an email to for 3D model requests.

« on: November 16, 2016, 03:08:56 PM »

Would you be able to tell me what the date code on the display is, or if possible to take a picture of the back of the display?

We have made a change which has larger thru-holes for our OLED displays.
However before this we traditionally used the TE 9-146282-0-20 single row pin headers for the older models.

Do you have a limit as to how much current your VDD line could supply?

OLEDs / Re: Meaning of Co bit in US2066 Controller
« on: November 14, 2016, 04:59:37 PM »
Responded via. Email.

The Co bit is a continuation bit, that tells the controller that the byte coming in next is data and it should be read.

TFTs / Re: Using NHD-1.8 Displays with a FFC connector
« on: November 14, 2016, 09:32:25 AM »
Hello Mark,

Unfortunately there are no standard ZIF / FFC connectors for the 0.8mm pitch connector, these would have to be soldered directly to the pcb.
We do offer the 1.8" TFTs with a FFC style connector, such as the NHD-1.8-128160EF-CSXN#-F
