Title: Diferences between NHD-4.3-480272EF-ASXV#-T and NHD-4.3-480272EF-ASXN#-T

Hi,

I have problems with the resistive touch panel in the NHD-4.3-480272EF-ASXN#-T, sometime when I touch the panel the system is like not respond for a variable time. The touch panel is conected to a ADS7846 using ferrites and capacitors. The system is a raspberry pi 3 with raspbian.

But when I use the NHD-4.3-480272EF-ASXV#-T the touch panel work far better the the first one. The only difference I see is in the TFT technology... The touch screen and the internal controller is the same.

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.
