It was revealed yesterday by the USPTO that Apple has invented a new laser beam focus system that is used on their production lines overseas. Apple's passion for detail drove them to invent their own laser beam calibration system so as to get their spot-welds just perfect. Would we expect anything less from Apple? And on another front this morning, we learn that Apple may shift from IPS to IGZO displays in 2012. A 32" HDTV prototype using IGZO was demonstrated in Japan in October – which may explain one of Apple's motivators for shifting to IGZO displays.
