Update drivers here: https://support.hp.com/us-en/drivers/hp-15-dw0000-laptop-pc/26185492 . If that doesn’t fix it, you can try attaching an external monitor. If the monitor displays fine but not the laptop, then the screen’s broken.
You can purchase a replacement screen here: https://www.laptopscreen.com/English/model/HP/15-DW0000~SERIES/ replacing screens is pretty easy, but take it to a shop if you prefer.
