Hi-res iPad screen to require new backlight solution?

Apple will likely need a new backlight solution should it adopt a high-resolution 2048 x 1536 display in a next-generation iPad, according to a new report. Citing sources at Taiwan-based back-light unit makers, DigiTimes reports that the single LED light bar found in the iPad 2 will need to be modified to maintain or strengthen the brightness of the existing display in a higher-resolution panel. The report claims that two alternative solutions have been developed—a single light bar with two LED chips inside or a design that utilizes dual bars—with the latter described as being the one Apple is more likely to adopt, as the back-light unit makers have reportedly solved issues related to heat dissipation and battery consumption for the dual bar design.
