The number of LEDs has been slashed in the iPad Air, allowing Apple to build a sleeker tablet, according to a new report.
More has been revealed about the iPad Air's internals, revealing a revamped backlight assembly that helped Apple to slash the battery capacity by 23 percent, according to a teardown report released Tuesday by IHS iSuppli.
The iPad Air uses only 36 light-emitting diodes (LED) to illuminate the LCD, down from 84 in the earlier-generation iPad, according to iSuppli.
"[That's a] big difference [and] has a big impact on the power requirements for the device," Andrew Rassweiler, Sr., director of Cost Benchmarking Services at IHS, said in response to an e-mail query.
"In part because there are fewer backlight lamps, the battery now has reduced capacity," he said.
As iFixit, the Air's 33 WHr, two-cell battery is "decidedly less monstrous" than the previous iPad's 43 WHr, three-cell power plant.
Apple didn't stop there, though. The thickness of the display and touch-screen subsystems has been trimmed too.
"The Air's display is 1.8 millimeters thick, compared with about 2.23 millimeters for the older-generation iPad. Meanwhile, the touch screen is also thinner with its use of an expensive cyclo olephin polymer (COP) film sensor versus the thicker and cheaper glass sensor used in the previous models," iSuppli said in its report.
