A newly patented technology from Apple, referred to as “Quantum dot enhanced display having dichroic filter,” might allow the company to achieve revolutionary display resolution in future apple products, Appleinsider reports.
As described by the website:
“Quantum dots (QDs) are technically nanocrystals – in some cases smaller than a virus – made from various semiconductor materials that exhibit special quantum mechanical characteristics. Of interest to display makers, as well as other industries in the optics field, are QDs’ light-emitting properties, [which] can be ‘tuned,’ or manufactured, to emit very narrow spectrums of light…In Apple’s invention, as with other proposed implementations, a dichroic filter is disposed on a quantum dot-enhanced film (QDEF) in an red/blue/green (RGB) LCD display.”
Given Apple’s tendency to leave various patented technologies untouched, it remains to be seen whether (or when) the above display enhancing technology will ever be implemented in future iPhones and iPads. As impressive as the retina displays are, major competitors like Samsung are already releasing products such as the Galaxy Note 3 that boasts even better resolution and color.
A recent article from Appleinsider’s Shane Cole, citing a study from AnanTech, also brought to attention the fact that the Retina iPad mini’s color gamut is less impressive than that of the current iPad Air, Google’s Nexus 7, and Nvidia’s Tegra Note 7.
“The iPad mini with Retina Display has the same color gamut as the standard iPad mini, which is narrower than the iPad Air and less than the sRGB coverage we normally look for,” Anantech’s Anand Lai Shimpai mentioned in his report. “The difference is small but apparent, particularly if you’re used to panels with full sRGB coverage like the iPad Air or any of the rMBPs/iMacs.”
