Turning on screen programmatically

Question

I would like to unlock screen and switching it on to show a popup on an event trigger. I am able to unlock the screen using

newKeyguardLock = km.newKeyguardL

I have the same issue. As these guys discussed here, there is a hidden api to turn screen on/off, see: https://android.googlesource.com/platform/frameworks/base/+/froyo-release/core/java/android/os/Power.java

But I don't know how to call it. I have actually seen a application can turn screen on, wondering if it is device specific.
