Title: One display for everything: touchscreen, solar cell, fingerprint sensor, heart rate monitor
Post by: Redaktion on May 02, 2024, 15:31:30
QLED, OLED, now PeLED. The new pixels do not promise better picture quality, but an all-round solution for smart and mobile devices. The functional principle is surprisingly simple, but makes numerous sensors superfluous.

Finally, perpetual motion (or in this case, energy), will be achieved! The light the display produces can keep it powered.

Seriously, though, I wonder how well the touch functionality would work. It seems like a shadow could be interpreted as a tap. And for it to work as a heart rate monitor on a watch, it would have to be on the underside, against the skin, at which point is it really a feasible replacement for a standard sensor? Definitely sounds interesting, too bad it'll probably be 15-20 years, if ever, before it's used.

They have to some extent, look up the recent progress on perovskite-silicon tandem cells with mass production starting this year
