Hi Peter,

Unfortunately most LCD's are not waterproof on their own. You would need to put inside of a waterproof enclosure. It seems you are already taking care of that with the carbon fiber enclosure.

Currently our 4.3" TFT is the only sunlight readable display we have available. We are planning to release a sunlight readable 7" TFT in Q1 of the coming year. This to will have a brightness rating of 1000 cd/mē. We will also have an MVA model of the 7" TFT as well, with the wider viewing angles, and a typical brightness of about 800 cd/mē.

To drive these displays you would need either a MPU that has a TFT controller built-in, or you could use an external controller such as the ones linked below with most MPUs.

NHD   8-Bit MPU Interface Controller: NHD-7.0-800480EF-20 Controller Board
NHD 16-Bit MPU Interface Controller: NHD-7.0-800480EF-34 Controller Board

Also the RESET pin is active LOW.

Connect that to VDD or a GPIO pin that is HIGH.


You can control the brightness of the NHD-0420CW-AY3. While it is brighter neither of these displays will be sunlight readable.

For sunlight readability and reduced power consumption I would recommend a traditional LCD display.
With the exception of the two negative displays (Blue background with white text) these will all be sunlight readable:

Hi Ashok,

Can you please tell me if you are initializing the display at all?
Also can you tell me the voltage you are applying to Pin 3 (V0) of the display?

Seeing boxes could mean that the display contrast voltage isn't set to the proper level, or the display isn't initialized and is waiting for the initialization sequence.

In 4-bit mode, you would need to send the upper 4 bits first followed by the lower 4. The comments are wrong for that display, I will have that fixed soon.

Would you be able to post a picture of the black boxes?

Hi would it be possible to post a picture of the black boxes.

Could you also check the voltage on pin 3 of the display?

You would not be able to control the Touch panel using the Controller board, the capacitive touch panel for this display is on a separate FFC connector, and it comes with a built-in controller.

I have already sent you the information for the evaluation kit via email.


The initialization process that occurs after reset does leave the display OFF.

You would need to turn it on.I would also recommend repeating the initialization that occurs after the reset if you're just booting the display up for the first time.


That does seem like the proper method to change the backlight, do you have any commands you call before that that would cause the command to not work.

Also what interface are you using with the display, and at what speed?

Would it be possible to take a picture of how the display looks?
It would also help if you can post the code where you are writing the characters.

You should be fine grounding the CS pin on the display, it will still work.

Would you be able to post the code snipped of how you are adjusting the contrast?

Customer Projects / Korg Wavestation (A/D & EX Models) LCD Replacement
« on: November 05, 2015, 10:08:32 AM »
This is pretty useful for anyone who want to replace the LCD for their Korg Wavestations (A/D and EX models). The backlight on these synthesizers uses and electroluminescent panel. These often have lower lifetime ratings, and could possibly burn out. These panels also require a power inverter that might emit an annoying high pitch noise while operating.

Here are links to a couple of customer projects which replace the LCD on their old Wavestations with the NHD-24064WG-ASMI-VZ#. (A/D) (EX)

The NHD-24064WG-ASMI-VS# has been replaced by the NHD-24064WG-ATMI-VZ#, this is an equivalent display, the only difference between the two is a difference in the LEDs used for the backlight.  Another option is the NHD-24064WG-ATFH-VZ# which has a FSTN(+) display.

Well thank you for the heads up.
