Looking at the Nextion data sheet for the enhanced 4.3, you’ll find that the version without the resistive touch has a luminosity of 250nit, and the version with touch 230nit. I’m not sure if it’s worth the effort.
The touch layer on resistive screens is not a thick glass, it’s a relatively thin plastic foil which floats at about 0.5mm above the LCD glass, and which has a separate 4pin connector on the logic board.
The new P series, they call it also „intelligent“ has a luminosity of 300nit which is about 30% higher.
They have also a more powerful CPU with multimedia support, more flash, and more bells and whistles. They exist actually in 7“ and 10.1“.
