OLEDs / Re: First time for OLED, HELP NEEDED!
« on: October 12, 2015, 08:07:25 AM »
Hi Lin,

The OLED you bought is a graphic display, there wouldn't be a cursor blinking. Before you are able to write to the display, you need to first initialize the display and then provide the pixel data.

You can use this example code to help you get started with programming the display and having it display data: Example Code

I am curious if you were interested in a Character OLED vs. the Graphic because you mentioned the blinking cursor. If this is the case I would recommend taking a look at either the standard Character OLED display or the Slim OLED displays.

This is what you will see when the display is initialized.

Have you tried writing to it?

Hi Bruce,

Unfortunately we do not have a replacement for that display that would match those specifications. We have a standard 4.3" display that has a resolution of 480x272.

It doesn't come with a built-in controller, you could get the controller board to go along with it or use a MPU with a built-in TFT controller.

On a side note, there are newer high brightness models available to help with readability in areas with a lot of ambient light.

To get the 3D model for this display please email a request to

There are multiple ways to mount it onto your case, You could create an enclosure with an opening for the display to house it, or even use some double sided tape to fix it into place.

To connect it to your mpu you would need the Molex 52892-1433 connecter mounted onto a pcb such as the NHD-COG14-36.

TFTs / Re: NHD-2.4-240320CF-CTXI#-FT ribbon cable question

The length of the cable is fixed for the standard display.

However it is possible to customize the display to include a longer cable, this would require a NRE cost along with a MOQ.

If you are interested in this please email:

Graphic LCDs / Re: NHD-C12864WC-FSW-FBW-3V3 booster

I was wondering if you could confirm the number of capacitors you have in the circuit along with the values you are using for the following commands:

Power Control Set
Electronic Volume
Booster Ratio Set
Voltage Regulator internal ratio Set

HI, is that 6V what you're seeing at Vout?

Also what type and values of capacitors are you using?

Hi Larry,

You shouldn't have any issues running both at 3.3V

OLEDs / Re: Shift position after "clear screen" instruction

I would take a look at page 22 on the Datasheet of the display for a example initialization sequence. The sequence does address the flipped bits. I would suggest adding those along with what you already have.

I will wire one up to see if I can recreate what you were seeing.

This might have something to do with the initialization of the display. This seems like it might be an issue with the Entry Mode command where the display isn't incrementing the position after a datawrite properly.

If you are sending an initialization sequence can you post that as well?

I was wondering if you could post a picture of what you are seeing.

OLEDs / Re: Instruction execution time for slim OLEDs?
« on: September 17, 2015, 04:23:32 PM »
I would say follow the timing diagrams.


Unfortunately we do not have a 16 bit controller board for the 5.7" TFT displays. However the NHD-5.7-320240WFB-ETXI#-1 does come with a 16 bit controller.

And for the month of September we have a 10% off sale on all of our TFT displays if you were interested in this display.

OLEDs / Re: Calculation of Font Addresses Multi‐Font Displays Help!
« on: September 11, 2015, 10:54:16 AM »
Hi, Here is some information if it can help at all:

  • The dummy Variable is 0xFF
  • You would want to save the information coming back from the MF Chip into an 8X8 Array. The MF chip will give you 8 sets of bytes. With the bytes, B0-B7 will be the font information.
  • The bits will be vertical, so you could display the information one of 2 ways, either using the bit that corresponds with the line you are currently writing and go horizontally, or go through each bit and write vertically

You wouldn't have to, the 6.8 ohm resistor is dropping the voltage down by 0.72 V so voltage drop across the backlight is 4.28V.

I just hooked up a the sample which I used to confirm the resistance to a power supply. While at 5V it is using 125 mA. so in this case the resistor is dropping the voltage by .75V, from which the backlight has a drop of 4.25V. You can attach a potentiometer to pin15 to drop the voltage further and decrease the brightness if you would like.
