Fewer LEDs mean leaner iPad Air, researcher says

| The number of LEDs has been slashed1 in the iPad Air, allowing Apple to build a sleeker2 tablet, according to a new report. More has been revealed about the iPad Air's internals3, revealing a revamped4 backlight assembly that helped Apple to slash the battery capacity by 23%, according to a teardown5 report released Tuesday by IHS iSuppli. The iPad Air uses only 36 light-emitting6 diodes7 (LED) to illuminate8 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 query9. "In part because there are fewer backlight lamps, the battery now has reduced capacity," he said. As iFixit demonstrated on Friday, the Air's 33 WHr, two-cell battery is "decidedly less monstrous10" 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 trimmed11 too. "The Air's display is 1.8 mm 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 cyclo12 olephin13 polymer14 (COP) film sensor versus the thicker and cheaper glass sensor used in the previous models," iSuppli said in its report. |
