brightness control

Hello everyone maybe someone has already encountered such a problem or maybe someone knows whether it is possible to adjust the brightness according to the values of the photoresistor on this display TFT LCD 3.5 ILI9486 ? Thank you for your reply !

Do you mean the brightness of the backlght or the display contrast?

Hey brightness of the backlight

Post a link to the actual item that you have bought.

We need to see a photo of the pcb.

You have a 3.5 inch "mcufriend" Blue Uno Shield.

I do not own this actual display, but I have an old model with ILI9481.
What value is R1 (my pcb has empty R1)
What part is U2, U3. (my pcb has HC245)

Simple answer. You can not control the backlight.
