Secrets of ipad Air power: LED lights halve profits by 45%

Dismantling figure Phoenix Science and technology news Beijing time November 6, according to AppleInsider website reported that the investigation company IHS Disassembly analysis, equipped with Retina display Ipadair, only use less than the previous version of the ipad half the number of LED lights, reached the same level of brightness, Energy consumption is significantly reduced. IHS estimates that the cost of Apple's Ipadair (16gb,wi-fi version) is $274, which is 42 dollars cheaper than the third-generation ipad. Although overall manufacturing costs are lower, ipadair display costs are rising (note: 9.7 inch Retina Display). At the same time, IPAD3 and IPAD4 used 84 LED lamps for screen lighting, and the ipad used only 36. According to IHS analyst Andrew Lasville (Andrewrassweiler), one possibility is that Apple uses higher-brightness LEDs, and another possibility, Apple claims, is that it uses some kind of optical film to properly distribute the illuminated light on the display. The use of optical films led to the reduction of the number of LEDs, which ultimately reduced the weight and energy consumption of the equipment. The weight of the ipadair is nearly 0.5 pounds (about 227 grams) lighter than the previous version, weighing only one pound. In addition, IHS estimates that the display and touch devices used by Ipadair cost 133 of dollars, with the cost of the display being 90 dollars. Other findings of disassembly analysis: 1, Ipadair only used a glass panel, and before the use of two pieces, thickness reduction. 2, Apple A7 processor chip cost of about 18 U.S. dollars, less than the A5 chip 5 U.S. dollars. 3. Ipadair's LTE chip supports the services provided by major wireless carriers across the United States, not iphone5s and iphone5c. 4, Apple from the Wi-Fi version of Ipadair (16GB) to obtain 45% net profit, LTE version Ipadair (128GB) net profit will be as high as 61%.
