According to a new report by DigiTimes, Apple will most likely introduce a new LED back-light technology in next-gen iPads. It is heavily rumored that the next generation iPad will sport a Retina resolution display. In order to maintain the brightness of such high resolution panels, the current single LED light bar designed for the iPad 2 needs to be modified as explained by sources in the supply chain.
LED back-light unit (BLU) vendors have reportedly offered two alternative backlight solutions for Apple to choose from for its next-generation iPad, according to sources at Taiwan-based BLU makers.
With the next-generation iPads expected to adopt LCD panels with resolutions higher than 2048 by 1536, the current single LED light bar designed for the iPad 2 has to be modify in order to maintain or strengthen the brightness of the panels, the sources explained.
One of the new LED light bar designs has proposed to keep the light bar in a single-bar form factor but with two LED chips inside; the other has suggested using dual-LED light bars, the sources indicated.
Apple is likely to adopt the design using dual light bars since BLU makers have reportedly solved issues related to heat dissipation and battery consumption for the dual light bar design.
