IPS Screen is prone to alcohol damage. Make sure to NOT use alcohol when cleaning your IPS Screen or BE REALLY CAREFUL to not let the alcohol seeps through the edges of the screen.
I had my IPS screen damaged by the alcohol when I installed it. I will include a photo below to show how the damages look like on my screen. Alcohol damages look like white dots or white boarders. They don't completely destroy the screen, just kinda of annoying to look at.
