Samsung's fight on the smartphone is still in full power, and after finding a way to move the selfie camera to the screen, their Display subsidiary is set to demonstrate its technology to move the earpiece to the same location.
The economic times in Korea report that Samsung Display will show its Sound on Display technology at CES 201
The technology uses piezoelectric actuators connected directly to the screen, which are then used as the speaker's membrane. The technology has the potential to be used over a wide surface of the panel, allowing for three-dimensional sound effects and greater directionality, and of course, making the waterproofing somewhat easier.
The technology works better with OLED monitors instead of LCD monitors, as these displays require a backlight that interferes with the transmission of the piezoelectric vibration.
Samsung is not the only one expected to showcase the technology at CES, while LG also has a 65 inch TV that uses the screen as a speaker, and several Chinese OEMs are also ready to commercialize the technology.
"A Chinese company is also developing technology to commercialize a smartphone equipped with a surface audio display," said an official working with local smartphone manufacturers. "There is the possibility of commercialization in the next half of next year as soon as possible."
The new technology will probably be late for the Samsung Galaxy S10, but we hope the Samsung Galaxy Note10 will be able to take advantage of the Sound On Display technology in the second half of 2019.
