Noting that the current backlight design on the iPad 2 is inadequate for a higher-resolution tablet, Digitimes is reporting that Apple is currently looking at two different options for LED backlighting on the iPad 3.

One of the new LED light bar designs has proposed to keep the light bar in a single-bar form factor but with two LED chips inside; the other has suggested using dual-LED light bars, the sources indicated.

Apple is likely to adopt the design using dual light bars, the sources asserted, adding that BLU makers have solved issues related heat dissipation and battery consumption for the dual light bar design.

The iPad 3 is rumored to be launching next year, with The Wall Street Times the most recent to confirm the expected release of the next-generation tablet.
