Nothing appears on the screen

it ran out of battery while working normally, after about 4 hours I went to charge it, there was no signal on the screen, it just blinked quickly where the notifications are on top but with very strange colors, I can click on the screen and feel the buttons on the screen (they vibrate) observations: it was in the shade but it was hot (38º) and it was side by side with another cell phone, like one on top of the other, it didn't fall, there was no damage for this to happen and when it was charging, it charged for more than 2 hours. (Redmi Note 11)
