The way forward for TV tech is just a single OLED ...

Researchers on the Pohang College of Science and Know-how (POSTECH) in Pohang, South Korea have unveiled a prototypical OLED show with a probably game-changing twist: the novel 13-inch panel is able to emitting not solely visuals, but additionally full-blown audio.

In a analysis article titled Localized Sound-Built-in Show Speaker Utilizing Crosstalk-Free Piezoelectric Vibration Array, published in Advanced Science again in April 2025 (via ScienceDaily), Inpyo Hong and Su Seok Choi define a display screen that may basically convert electrical alerts into full-blown sound vibrations utilizing piezoelectric know-how.

“Piezoelectric speakers straight convert electrical vitality into mechanical movement through the inverse piezoelectric impact, enabling environment friendly sound technology with a light-weight, versatile, and low-power design. Their easy layered development, consisting of electrodes and piezoelectric supplies, provides benefits reminiscent of low value, excessive vitality effectivity, and compactness,” write Hong and Choi.

What’s Pixel-Primarily based Native Sound OLED know-how?

A conceptual multi-channel sound system the place every pixel emits its personal audio

Dubbed Pixel-Primarily based Native Sound OLED know-how by the POSTECH researchers, a central innovation employed on this idea is the embedding of Piezoelectric exciters straight into the body of the 13-inch OLED panel in query. This circumvents the necessity for conventional audio exciters, which take up a considerable quantity of bodily area to supply sound by means of their driver component and different required speaker internals.

Piezoelectric tech itself is not new — we have seen client electronics manufacturers experiment with it up to now, reminiscent of with the Google Pixel 5’s grill-less front-facing speaker hidden behind its show. This all-new implementation of Pixel-Primarily based Native Sound OLED tech is distinct, nonetheless, with its pixel-like association and embedding straight into the OLED panel {hardware} itself. The tip result’s an OLED display screen association that may produce audio at a per-pixel stage, very similar to how every particular person OLED pixel can already emit its personal mild.

Based on Hong and Choi, these piezoelectric exciters might be demonstrably built-in into the body of an OLED show with out considerably impacting the form and dimension of the panel itself, all whereas eliminating crosstalk (sound supply leakage) and bolstering acoustic precision, positionality, and localization.

Samsung’s new OLED tech will make TVs as thin as a credit card

Samsung has unveiled its new UT One OLED show know-how, which guarantees ultra-thin and energy-efficient shows sooner or later.

Is Pixel-Primarily based Native Sound OLED know-how the way forward for TV?

Price, manufacturing, scaling, and high quality are all boundaries that have to be labored by means of

Conceptually, Pixel-Primarily based Native Sound OLED know-how is an thrilling prospect. OLED panels are already thought of best-in-class for his or her skinny and versatile design, their per-pixel management of sunshine emission, and their deep blacks and punchy distinction ranges. The addition of pixel-perfect audio emission has the potential to bolster the coveted ‘ 3D spatial audio‘ or encompass sound impact that some client manufacturers try to attain, whereas additionally obsoleting cumbersome speaker {hardware} within the course of.

“This know-how has the potential to develop into a core characteristic of next-generation units, enabling glossy, light-weight designs in smartphones, laptops, and automotive shows – whereas delivering immersive, high-fidelity audio,” writes Hong and Choi within the analysis paper.

In fact, the findings of Hong and Choi are experimental and function a proof of idea — Pixel-Primarily based Native Sound is not a consumer-ready know-how that may be churned out on a manufacturing line, and it doubtless will not be for the foreseeable future. With a purpose to obtain the size needed for mass industrial manufacturing, audio efficiency must obtain cost-to-performance parity with current client audio units, and probably different hurdles will have to be conquered.

There’s additionally no telling whether or not this tech will scale properly to larger-screened and smaller-screened units, or whether or not piezoelectric exciters will in the end be capable of obtain the audio outcomes shoppers anticipate out of their TVs, smartphones, and different tech devices (current implementations of piezoelectric tech, reminiscent of on the aforementioned Pixel 5, have not precisely taken the world by storm).

Personally, I am hopeful of a future wherein Pixel-Primarily based Native Sound not solely hits the patron area, but additionally achieves essential mass. Audio directionality and spacial contextualization can significantly elevate the expertise of consuming media, and that is double true relating to augmented actuality (AR) and digital actuality (VR) headsets. If cumbersome traditional speaker hardware had been to in the future develop into antiquated, it’d additionally open up the door for even thinner tech merchandise throughout the board, which is an thrilling prospect certainly.
