Expert: iPad heat claims overblown, not a real issue

According to Electronista report, DisplayMate Technologies Corporation President Ray Soniera pointed out that the new iPad (3rd gen)'s Retina Display should run a bit warmer than previous model. He also stated that web “overblown” this issue.

Electronista.com wrote:The third-generation iPad uses 2.5 times as much backlight power to illuminate the new display at the same luminance levels as the previous model, Soniera found. The high pixels-per-inch (PPI) ratio of the new display makes the LCD have a lower light efficiency and thus power efficiency. The doubled number of LEDs also give off 2.5 times as much heat, but remarkably the new battery in the iPad manages to (mostly) compensate for the increase.

(...)

The combined extra heat of the display, the more powerful processor and graphics chip and the heat generated by the battery itself would not be able to sustain the new iPad for long if the heat-dispersal capabilities of the device were not up to par. Apple has issued a statement saying the new iPad operates within the devices' temperature specifications, but users may want to be way of covering the back of the device with a form-fitting enclosure that doesn't also promote heat dissipation.

According to Wired Magazine's test, the new iPad (3rd gen) is not that hot after all. Except people like to make a huge fuss about it. Kindle Fire is even hotter than iPad (3rd gen).
