Hi David,

There should be no differences between the touch panel used between the two displays.

The only difference between the displays will be the backlight and polarizer used to provide the wide viewing angles for the NHD-4.3-480272EF-ASXV#-T.

Our displays / CTP panels come with the FT5X06 controller.
Doing a quick search I wasn't able to find the register values for this controller.

I would recommend contacting the company you bought that from to see if they have any example code / drivers for this controller.

Hi Gerrit,

A vacuum shouldn't damage the display.
However it does seem that an autoclave does use high heat and possibly steam, both of which could damage the display.

You would want to keep the display dry at all costs, any liquid that forms on the display could damage it.
You would also want to keep the display below 80 C. Higher temperatures can damage the Liquid Crystals and you would have dark spots that form. These would not be reversible.

Another option i would recommend would be our Chip-on-Glass displays specifically the NHD-C0216CiZ-FSW-FBW-3V3.
However this display does have a 3V interface ans will require 2 external capacitors and 2 pull up resistors.

Like you mentioned above with the NXP PCA9564, you could use a LCD Backpack that would allow you to convert from the I2C to the 8-Bit Parallel.
LCD Backpack:


There are no current limiting resistors built into this display.
The resistors on the pads have a value of 0Ω.

If you take a look at the bottom picture here:
You can see the values of R1-R3 are 0Ω.

Would you be able to post a picture of what you are seeing. I will try to recreate the issue as well to see if i can find a sollution.

Sorry this took a little bit longer, Please see the attachments:

Many of our displays have solder bridges or jumpers that can be moved to reverse the polarity of the backlight or even provide the power for the backlight via the VDD and VSS pins.

Do you have a certain display you are looking at to match the display from the Elise cluster?

You could power it through a 5V so long as the supply can provide enough current to run the backlight as well. Most MPUs would allow for this.
The display does have internal pull up resistors, so you will not need to worry about providing those externally.

I will make a few wiring diagrams tomorrow.
If you want to order the cables I will tell you which ones will work as well.

Thats good to hear, luckily the last 2 pins are no connects, so you shouldn't have anything short out on the board.

Do not apply 19V to the board.

What is the current allowance for the VDD pin you are applying?

Did you try to power this display on with 19.2V at all?

The backlight enable pin is not directly connected to pin 2 of the TFT. The Controller itself has a built in voltage booster, which is tied to VDD.

The backlight enable pin can be tied to a GPIO or be left floating for the backlight to power on.
