The benefit of an LED display goes beyond just the environmental benefit. LED backlights don't have a warmup time like CFL backlights, and they provide a more uniform brightness level across the panel. The panel will also be cheaper to run over the lifetime of the device because of its energy savings (lower TCO, to borrow a term from the server community). The fact that they are mercury free is just one of many reasons why LED backlights are considered a marketing point.
