Bare display pcb connections

Other Hardware Displays

Hi,

I' have a few question. I have ordered a bare display for my project ( space requirements)
I have a question

-That is the display i ordered - resistive touch.

Here it states " The LED backlight driver IC we suggest to use for this display is [PT4110]"

I've learned how to draw a simple board with traces and correct spacing.
Now do I really need this PT4110, if im going to use the board with esp32.
If yes,
where does this "driver" go, where do i connect it

This is my first ever bare display.

According to the pinout, here are the pins mentioned in the image where you will connect the driver
You could have chosen other 3.2 inch display with builtin control over backlight

Thank you,
I just now saw an ILI9341

This one has the built in drivers?
