My Galaxy S4 had the same problem. After waking up the lock screen, it would dim after 5 seconds.
Try Settings, My Device, Smart Screen, then check the box to the right of Smart Stay.
When the lock screen displays, make sure your face is in front of your phone. The screen stays lit as long as your face is seen by the front camera.
I found out from another forum that the 5 second lock screen timeout is not adjustable.
