   There are a couple cases to consider:   
      
   1) Disable driving the screen. Good for panel types   
      where the emission of light, wears them out.   
      
   2) Varying the pattern over the screen surface, and   
      keeping the panel running. Plasma might have been   
      one technology where some of the users liked this method.

   For a lot of users, the topic will be irrelevant. My LCDs   
   here, don't need any special handling.   
      
   There are things that wear on an LCD panel, and blanking the screen,   
   turns off the CCFL tubes or the edge lighting LEDs.   
   The intensity of CCFL tubes, drops around 25000 hours   
   of usage (assuming the inverter for each tube, lasts   
   that long). Some inverters fail after only a year or two   
   of usage. LEDs are roughly the same, 25000 to 50000 hours   
   before they reach only 70% output. Modern LED screw-in   
   light bulbs have a 10,000 hour rating, and that covers   
   the SMPS failure in the base of the bulb.
