In the ongoing pursuit of making touchscreens feel a little less flat and smooth, researchers at Aachen University in Germany have created a prototype display with embedded magnets that provide a tactile response to users interacting with on-screen elements.
It's old news by now, but capacitive touchscreens are a pain to use in the winter because they can't detect your fingertaps through a pair of gloves. But SMK has improved the design of their 6.5-inch panels so that devices like car navigation systems can still be operated if you're driving with gloves on.
FlatpanelsHD put together an interesting analysis of why Samsung's Galaxy Nexus' 4.65-inch, 1280x720 Super AMOLED screen probably isn't comparable to Apple's 326 ppi Retina Display despite having a pixel density of 315 ppi. The reason: PenTile technology.
Apple raised the bar with the iPhone 4 by cramming an impressive 326 pixels per inch into its display. But Toshiba has officially dethroned them by upping that to 498 pixels per inch on their new LCD targeted at compact tablet devices.
