Apple Implementing New Back Lighting System in iPad 3
is reporting that Apple is planning to change how the iPad 3 is back lit in order to support the device's much rumored Retina Display.
According to the report Appleís next-generation iPad will utilize a LCD panel with a higher resolution of 2048 x 1536 pixels. Apparently the increased resolution means the current iPadsí single LED light bar solution wont be enough to illuminate the iPad 3ís retina display.
Vendors have offered up two solutions to Apple so far. One is to use a similar single-bar LED setup but use two LED chips inside. The other solution is to use dual-LED bars. The dual-LED light bar design will likely be the design Apple chooses according to Digitimes
, as the vendors have solved heat dissipation and battery consumption issues.
The last comment is particularly concerning. Battery life is a huge issue with tablets, and a particular strength of the iPad. The benefits of the iPad 3ís retina display are potentially huge, but if the downside is crippled battery life count me out. Powering two LEDís instead of one, if done poorly, could be damaging. But, this is all speculation. Digitimes
has a hit-and-miss history with Apple rumors. Hopefully these problems implementing a Retina Display in the iPad 3 are more miss than hit.
