Subretinal implant uses light instead of batteries, shows promise in initial testing
There's been significant progress in bringing sight to the blind in recent years, and this looks set to continue that miraculous trend. Scientists at Stanford University have invented a subretinal photodiode implant for people who have lost their vision due to degenerative retinal diseases. Existing tech involves batteries and wires, but the new implant works without such crude appendages. Instead, it's activated by near-infrared beams projected by a camera that's mounted on glasses worn by the patient and can record what the patient sees. The beams then stimulate the optic nerve to allow light perception, motion detection and even basic shape awareness. It hasn't actually been tested with humans just yet, but the first few rodents volunteers have yet to lodge a single complaint.
Hitachi's 4.5-inch IPS display has 1280 x 720 res, 1,100:1 contrast, plans for mass production in October
Yo, Apple, you know that Retina Display you're so proud of? Old news. Hitachi Displays has just announced a 4.5-inch IPS LCD panel that fits 1280 x 720 pixels within its frame, accounting for an eye-watering 329ppi density. That's higher than you can get on the iPhone 4, but the fun doesn't stop there. Hitachi's new goodness also promises an 1,100:1 contrast ratio and 500 nits of brightness coming from an LED backlight. This precious new slice of technology is predictably all geared to land in your future smartphone of choice and we're told mass production is set to begin in October of this year. That basically means CES 2012 is going to be filthy with handsets offering full 720p resolution -- we can't wait.
