Apple Said to Shift to Lower Power IGZO Displays for MacBook Pro Later This Year

Apple will shift to indium gallium zinc oxide (IGZO) material for MacBook Pro displays as soon as later this year, according to IHS. The research firm told DigiTimes that Apple may continue to procure MacBook Pro displays based on current amorphous silicon (a-Si) material until the end of the first quarter. The report claims Samsung and Sharp will begin supplying IGZO panels to Apple as soon as mid-2017. Sharp began mass production of IGZO displays in 2012, but evidence points towards Apple only using the material in iPads so far. A rumor claiming the first IGZO MacBooks would launch by 2014 proved to be inaccurate. IGZO is a semiconducting material that has forty times more electron mobility than the standard a-Si used as the active layer of an LCD screen, allowing for less power consumption, improved touch sensitivity, and increased pixel density, which could pave the way for higher resolution displays. DisplayMate president Raymond Soneira told us IGZO can also result in "significantly higher brightness," but the material costs "considerably more" to manufacture. Production and yield issues have slowed the adoption of IGZO, but the material is now showing up in more products such as LG's new OLED TVs. "Sometimes IGZO is simply referred to as Metal Oxide," he added. "The higher the PPI and the wider the Color Gamut (like DCI-P3 for the new MacBook Pro) the greater the benefits of IGZO over a-Si, particularly for LCDs." The glass edge and backplane circuitry of IGZO displays can also be made smaller, possibly leading to a thinner MacBook Pro. However,

12.9-Inch 'iPad Pro' Again Rumored to Have Oxide LCD Display

Apple's much-rumored 12.9-inch "iPad Pro" could have Oxide LCD display technology and will enter mass production in the third quarter of 2015, according to DigiTimes. The report, citing sources within the supply chain, claims that Apple has elected to use oxide panels for the tablet after weighing the cost versus performance of display technologies a-Si, TFT LCD and Oxide LCD."Market rumors over the last six months have stated that Apple would aim to release the device in the first half of the year, with mass production occurring in the first quarter. The company, however, has been assessing different panel technologies ranging from a-Si, TFT LCD and Oxide LCD in terms of cost versus performance, and has only recently decided to move forward with Oxide technology."The report adds that Sharp, LG Display and Samsung Display have been sending Apple display samples as they compete to secure component orders for the iPad Pro. Sharp is expected to be the main supplier due to its advantages in Oxide LCD display production, with LG also in the running to be a secondary vendor. The panel suppliers will reportedly produce limited supply in May and begin mass production in July and August. KGI Securities analyst Ming-Chi Kuo, who has a respectable track record at reporting on Apple's upcoming product plans, also forecasted in November that the iPad Pro would be es">equipped with an oxide panel for "high resolution, quick response, and high color saturation," with manufacturing difficulties pushing mass production of the tablet into the second quarter of 2015.

Apple's iPad Air Adopts IGZO Technology for Thinner, Lower-Power Displays

Apple's new iPad Air marks a significant technological step forward for the company, improving performance while reducing the device's volume and weight by over 25%. Much of the size and weight savings have been enabled by improved power efficiency, allowing Apple to reduce the device's battery thickness and capacity by roughly the same 25%. Component thickness reduction in iPad Air As noted in IHS iSuppli's component cost analysis released earlier today, the iPad Air now uses just 36 LEDs to light its display, down from as many as 84 in previous generations. Apple has also reduced the thickness of the display assembly, and so it appears that the display is indeed one of the areas where Apple has been able to make the most improvement on size and weight, both in the components themselves and in the battery capacity needed to drive them. In a new analysis comparing the iPad Air's display to that of the Kindle Fire HDX 8.9 and the Google Nexus 10, Ray Soneira of DisplayMate Technologies confirms that Apple has indeed changed display technologies in the iPad Air, moving to indium gallium zinc oxide (IGZO) semiconductor materials from the amorphous silicon (a-Si) compounds used in previous iPads. While rumors of Apple moving to IGZO for the iPad and other products have circulated for several years, Sharp has experienced difficulties ramping up production and it has taken until now for Apple to bring the technology to its products. Among the evidence cited by Soneira for his claim that the iPad Air has moved to IGZO technology are power measurements showing that the
