3.95 MCU Friend Arduino TFT LCD flickering
I think something is wrong with this LCD board. This is because in my case the display works sometimes perfectly with the ILI9481 driver but sometimes something hangs and the display starts to flicker. It looks like a chip charging problem. Anyway I solved the flickering problem by tuning the ILI9488 registers. Simply you have to change the initlcd.h for ILI9481 driver in UTFT library.
