screw in picture looks like torx to me
display type should be on the cable (-2.02 + barcode in picture), but display type is printed on the backside, so you have to lift the latch on the connector and take the cable out to see
we just had another display repair thread

not your device, but maybe some generic advice
good luck
PS: an elbow can break more than just the display, try to confirm that the device still runs fine otherwise (like does LED blink as it should when you reboot or whatever)
PPS: I see this has one more cable than H2O, maybe the touchscreen...? no idea if this is one unit with the display or separate.
