You can use following command to trigger display ON. adb shell input keyevent POWER

I tried and am using in my project, Hope it will work for you.

And here is the ruby code I used:

def ScreenCheck()
system("adb shell dumpsys power > c:/interact.log")

File.open("C:\\interact.log").each do |line|
    if line[/mScreenOn/]
        if line.strip == "mScreenOn=true"
            p "Screen is On, Starting execution.."
        else
            p "Screen is Off, starting screen.."
            system("adb shell input keyevent = POWER")
            p "Starting execution.."
        end
    end
end
end
