An interesting sound-emitting display concept by Samsung got our attention when showcased at the Society of Information Displays (SID) 2018 expo last month. As you can see in the video above, the Samsung rep explains how a panel using vibration and bone conduction may negate the need for an earpiece, helping extend the screen all the way from top to bottom. They had a "Sound on Display" tech prototype at hand, running in what seems to be a Galaxy S9+ casing, and the presenter joked that we are actually looking at the Galaxy S10 display here.
6.2 inches. Coincidentally, this is the size of the S9+ display, so we keep our hopes high that Samsung could introduce an edge-to-edge Galaxy S10 with the panel of the S9+, but an even more compact body. Sweet!
the edge-to-edge NEX, which might be a harbinger of things to come next year. Vivo calls this Screen SoundCasting, and says that "compared to other audio solutions for bezel-less smartphones, it conserves power, reduces sound leakage, and optimizes low to high pitch sound for a better and more balanced audio experience." Word.The transmission bandwidth is said to be in the 100 ~ 8000 Hz range, and, thanks to the very fine vibrations, you would only hear the sound if you put your ear to a fairly wide area at the top half of the screen, denoted with a circular symbol here. In fact, Vivo just announced one phone with such technology,
In fact, LG already has a product with a sound-emitting screen on the market, its Crystal Sound line of OLED TVs and LED lights, and it apparently plans to bring the technology downmarket to its phones, too. Samsung also demonstrates a touchscreen panel that can work under water, so that's another area to dream about when it comes to the 2019 Galaxy or Note crop.
