CRT Burn

Back in the days of Cathode Ray Tubes (CRT’s) a major concern was CRT burn. When a static or near static image was displayed on a CRT for a long time the phosphors would burn off leaving a ghost of the image imprinted on the display. The only way to repair the damage was to replace the cathode ray tube itself. That was a very expensive proposition. I leave my chart plotter (actually multifunction display) on almost all of the time. It serves as my alarm clock, severe weather alert, and channel selector for the XM radio on board. In proof of the truth that old ideas die hard one morning I woke up and said to myself: “OMG I am burning a hole in the multifunction display as the chart of Fairfield Harbor never moves!” It took a couple of minutes to remember that LCD displays can’t burn. Lots of laughs.

 

Fair winds and following seas.
