iPad 3 Could Feature Dual OLED Backlights

Apple is looking to improve display technology on its next generation iPad, and we're not just talking about a Retina display resolution. A patent filed by Apple in the first half of 2010 reveals designs for dual OLED backlights, as reported by Patently Apple. The diagram below shows a cross section of the OLED backlight layers.

Part of what makes this technology so impressive is its simplicity. Current LCD displays have multiple layers requiring more thickness, and as has been seen in the past on the iPad and iPhone, they can be prone to manufacturing problems. Light leaks and yellow discoloration have been reported on some defective units.

Next Generation iPad Coming in 2010?

No way. Leave it to DigiTimes to keep the iPad rumor mill in full swing. The publication has reported that new iPad models could be on the way as early as fourth quarter 2010. Considering that Apple has had a difficult enough time delivering three million units sold to date, this doesn't sound very likely.

In the same report, DigiTimes cites sources in the industry who claim Apple has placed orders for OLED screens from Taiwanese component maker Compal. The current iPad features an IPS LCD display, the most expensive single component featured in the hardware design. OLED screens are still more expensive to produce, and even OLED giant Samsung Electronics is having trouble fulfilling orders for its own products.
