Future Devices Could Include Screens That Look Better In The Outdoors
May 26, 2011
Future iDevice screens could include improved LCD displays that won’t become distorted when viewed by a user wearing polarized sunglasses outdoors. Apple was discovered to be working on this new technology thanks to a recent patent filing, first uncovered by Apple Insider.
Called “Display that Emits Circularly-Polarized Light,” the proposed invention is said to reduce “perceived distortion when viewed through linearly polarizing filters, such as sunglasses.”
The problem, according to Apple’s patent filing states:
In the application, Apple notes that current LCDs are based on polarization optics, and typically utilize linear polarizers on their front surfaces. The problem is that the light from LCDs typically has an electric field that only vibrates in one direction, while polarized sunglasses only allow through light with an electric field that vibrates in the vertical direction.
By creating a screen that better accommodates sunglasses, Apple could improve the ability to use devices such as the iPhone, iPad, or MacBook Pro outdoors. What do you think? Leave your comments below.
