Can you access recovery? Power off the device and hold volume up+volume+home+power until the recovery loads. If it does, scroll down using volume down and power to select factory reset. Reboot when it finishes and see if everything is improved.
If it doesn't, then it's likely a bad screen that needs to be replaced. You can look online for information to do it yourself or send it to repair.
