![]() That translates to even thinner touchscreens. In “on-cell” setups, used in current smartphones, the touch sensors reside on top of the color filters - in “in-cell” configurations, they’re actually inside the color filters. What the heck does “in-cell” refer to? The position of the touch sensors in the panel itself. Rumormonger DigiTimes says Apple’s next iPhone will probably use what’s called “in-cell” touch panel technology when (okay, if) it rolls off the assembly lines this summer or early fall.

By designing a complementary imaging processor using CMOS (Complementary Metal-Oxide Semiconductor) technology. Kenneth O, Texas Instruments Distinguished Chair and TxACE director. “The combination of CMOS and terahertz means you could put this chip and receiver on the back of a cellphone, turning it into a device carried in your pocket that can see through objects,” said Dr. Terahertz waves pass through just about everything save water and metal, including paper, wood, plastic and - because it’s the nervous question on everyone’s mind when talk of plausible, portable X-ray vision pops up - clothing, too.

Times notes, it could be put to work helping detect skin cancer and locating unseen cracks in objects or studs in walls. But imagine the technology bettered, miniaturized and manufactured cheaply enough to make it usable in everyday phones, where, as the L.A. The whole “see through stuff” part is old news, of course: Cameras that detect infrared radiation can “see” through cotton-based clothing, for instance, and have been around for years. Let’s start with smartphones packing cameras capable of what we used to call “X-ray vision,” which researchers from the University of Texas at Dallas claim could be just around the corner. Follow with cameras that let you see through walls, paper or clothing? An iPhone with a case made of “liquid metal” and - wait, what’s an “in-cell” touchscreen?
