Q: i know my password but in the screen show ( iPhone is disabled)

Once you get to the disabled screen there is nothing that you can do now. You must restore/erase the device as instructed in the support article .

If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled - Apple Support

The issue might not be related to the passcode at all. The title of that support article says that if you forgot the passcode OR the device becomes disabled. The device can be disabled due to a software problem. That can happen at any time and has nothing to do with the passcode at all.
