NEW LAUNCHES OF APPLE

          Apple launched a new version of its iMac desktop computer in California, with a 27inch retina display. It will go on sale today, starting at $2,499.

          The new iMac brings the high resolution retina display – first introduced on the iPhone and iPad, then the MacBook Pro in 2012 – to the desktop.

        The main feature of desktop is that the “retina 5K” display will have a native resolution of 5120x2880 pixels, leading to a 14.7 megapixel display.That boosts the resolution and pixel density, but in keeping with Apple’s approach to mobile devices, it uses it to make text, icons and pictures sharper and easier to read, rather than simply making everything much smaller and adding more screen real estate.

              The new iMac maintains the slim all-aluminiumdesign, introduced in 2011 along with Apple’s Thunderbolt port for fast external connections, while the internals are upgraded with a 3.5Ghz quad-core Intel i7 and an AMD Radeon R9 M290X graphics card.

        Since 1998 the iMac has seen several revisions, moving to an articulated flat screen in 2002 and then to the basis for the current aluminium bodies in 2004. Apple continued to update the iMac internally, switching to Intel processors from IBM Power PCs.

          The iMac has steadily replaced the Mac Pro as the machine used by most desktop Mac users, including publishers and artists, with only video producers clinging to the more expensive, but more powerful Mac Pro.        

                 

         

         On December 27, 2012, the US Patent & Trademark Office published two display related patent applications from Apple. The first patent generally relates to liquid crystal displays (LCDs), and, more specifically, to a coated chassis for an LCD. According to Apple, the chassis could be made from a non-conductive material and be operable to support displays found on the iPhone, iPad, MacBook and even the touchpad on MacBooks. The coating could advantageously prevent or reduce noise in the device's antenna usually caused by the LCD. Because the conductive material adds little or no bulk to the device, it's able to maintain a compact size. 

     The second patent relates to LCDs that include a panel having an array of metal oxide TFTs, which may be configured to reduce visual artifacts by providing reduced RC loading and parasitic capacitance, thus improving overall image quality. In one embodiment, the display may be a high-resolution LCD display having more pixels per inch, such as a Retina Display.
