Can I use the iPhone display without original Home button?

Hi,

I am a new mobile service Person. Like to create a LCD Display testing environment . When I purchase LCD Displays from the supplier, i like to test these screeens in my test environment before installing it in my Customer's phone. I have already tried LCD testers (from China), but they are not reliable. So i am purchasing a used iPhone 6, remove the original Display, extend the Flex cable. With this Setup , i like to test new iPhone 6 LCD Displays everytime. but my question is , should i put my original home button to the new Display everytime ? or just fine operating the iPhone with the new Display without the home button ? I don't like to lock my iPhone due to Touch ID Problems. Please help me with this. Thanks in advance.
