My laptop- Pavillion x360 -13s121ds screen is half black & jiggles

My laptop model Pavillion x360 -13s121ds screen was half black and jiggles after I open the top part of the screen and wipe the dust off. I think I crack the top part that’s why its black. the display of the desk top appear at the bottom part of the scree and the display jiggles and changes colour every now and then. The worst part is the cursor is not steady. its moves around like crazy . how can I fix this? do I need to replace the screen (touch screen)?.. I need help.
