Sound straight from the screen: revolutionary technology from Korean scientists
Scientists from South Korea from the Pohang University of Science and Technology (POSTECH) have shown the world a display with innovative technology - local sound transmitted directly from the surface of the screen!
How does this work?
The secret of this technology is the use of piezoelectric exciters placed under layers of organic light-emitting diodes (OLEDs). These tiny elements convert electrical signals into vibrations, creating sound.
Each point on the screen, each pixel, acts as a separate speaker, forming a multi-channel sound array without the need for additional drivers. The sound is clear, without the crosstalk that often occurs in panel speakers of other technologies.
Prototype and Prospects
A prototype of the new 13-inch display, comparable to tablet and laptop screens, has already been created. Tests have shown that the sound is stable even when the input voltage and distance to the listener change.
POSTECH technology allows the screen size to be kept thin, making it very attractive to manufacturers of tablets, laptops, car dashboards and other devices.
The exact timing of the technology's release to the market is not yet known.
