A Korean news site has reported that Apple Inc. has been quality testing displays from the two world’s largest manufacturers of LCD panels: Samsung and LG, with a view include advanced display technologies in its next generation iPad,iPad 3.
Apple’s testing process with the new high-resolution screens is expected to be completed in the third quarter of the year 2011.The news site reported that the display of iPad 3 will support quad extended graphics (QXGA), and a display resolution of 2048 x 1536 pixels with an aspect ratio of 4:3 to provide full HD viewing experience.

“Apple’s upcoming iPad 3 will feature an improved display to support quad extended graphics (QXGA), a display resolution of 2048×1536 pixels with a 4:3 aspect ratio to provide full high definition (HD) viewing experience’’
The report also stated that Apple has started quality testing Samsung and LG LCDs at one of its laboratories in China. Apple’s decision to work with Samsung comes with a surprise , especially when the Cupertino based company is looking to cut ties with the Korean based manufacturers and planning to reduce the component orders as a result of legal action against the vendor. But the same cannot be said for the Samsung’s chip manufacturing business. Various reports have indicated that Apple is working toward a new partnership with Taiwan Semiconductor Manufacturing company to create ARM based processors, a component expected to feature in Apple’s next generation Smartphone and tablet lineup.
The report also mentioned that Apple has no interest in creating screens based on OLEDs ( organic light emitting diodes ). It was also said that OLEDs have shorter life spans and are easily contaminated, particularly when extended beyond 5-inches. The report also added that the current OLED technology is not mature enough to realize a full high definition viewing experience.
Both Samsung and LG are at ease of making highly advanced LCD screens and are capable of providing high resolution QXGA screens up to 9.7 inches, due to advanced production technology based on the use of low temperature polysilicon.
The vendors are also likely to increase the PPI (pixels per inch) to meet Apple’s strict pixel density requirements which are believed to be close to 280 pixels-per-inch for the iPad 3 display.
