This is how the finger looks as currently configured. Note the layer of cardboard between the LCD and the copper. This should provide a small amount of insulation so that most of the energy goes into the finger and thus into the body of the camera rather than being wasted on cooling the LCD. Currently there is a thin layer of thermal compound on this copper plate to improve transfer of heat.
