Sound on Display is a technology by which the audio associated with a display emanates from the screen itself, thus eliminating the need for inbuilt speakers. LG has demonstrated this innovation in TVs; now, Samsung appears poised to integrate it into smartphones. The OEM's take on this breakthrough may be showcased at CES 2019.

Many smartphone OEMs (those who use Android, at least) seem to be gravitating towards design tweaks that move them out of notch territory into that of the truly full-screen display. On the other hand, how are they supposed to do this while retaining the front-firing hardware needed for functions such as voice calls? Surface sound-display technology may be the answer to this quandary.

This innovative solution effectively turns a given display into a diaphragm, which is made to vibrate at the necessary frequencies by a speaker coil connected to a piezoelectric sensor. This, then, obviates the front-facing module for voice calls that is often housed in the notches of most up-to-date mobile devices. It may also have the advantage of reproducing the sound in accordance to where it 'appears' on screen. This could make device audio more realistic and '3D' while using content such as movies.

LG has already unveiled its take on this surface sound-display technology, which is known as Crystal Sound OLED (CSO). It is likely to be integrated into the OEM's next-gen TVs. Now, however, it looks like Samsung is on the point of catching up to this level. This company reportedly demonstrated its own version of CSO, known as Samsung Sound on Display, in a mobile device-sized display in South Korea this year. Now, it may intend to showcase the same at CES next year.
