White Green Screen screen with bars issue in iPhone XS Max

Dear community,

I am having issues with my iPhone XS Max, it all started one day when charging my phone the screen started acting randomly with some green colors in the screen then turning all white so what I did was to disconnect it then turn it off and after an hour so I turned it on again and it was working correctly. Days go by and the problem happened again but this time it was permanently. I have attached some pictures because it is really hard to describe but this problem happens like within 3 seconds and it ends up with black screen. This always happens like for example if I press the power button or even just pressing at the screen so it lights on. The touch itself works because even though I cannot see anything I am able to put my pin code and it turns on correctly i can use it like mirror to an apple tv then I can see the phone. I checked one video there could be software issue or even hardware that came with the phone. However I no longer have guarantee

Thanks for your help
