  • World’s First Pixel-Based Sound-Emitting OLED Display Created

    World’s First Pixel-Based Sound-Emitting OLED Display Created

    Key Takeaways

    1. POSTECH researchers developed the first “pixel-based local sound” OLED panel, allowing each pixel to act as a speaker.
    2. Ultra-thin piezoelectric exciters are used to create localized sound without crosstalk, resolving common audio interference issues.
    3. Acoustic optimization techniques, including specially tuned frame structures, improve sound quality and reduce distortion.
    4. The innovation maintains a slim design while delivering accurate spatial audio, suitable for tablets, laptops, and car dashboards.
    5. There is currently no information on the availability or pricing of this technology for consumer products.

    Researchers from Pohang University of Science and Technology (POSTECH) have introduced the first “pixel-based local sound” OLED panel, which incorporates audio playback directly on the display surface. A 13-inch prototype—similar in size to tablet and laptop displays—shows how every pixel can function as an individual speaker, forming a multichannel array without needing external drivers.

    Innovative Sound Management

    Led by Professor Su Seok Choi along with Ph.D. student Inpyo Hong, the team has installed ultra-thin piezoelectric exciters underneath the OLED layers. These exciters transform electrical signals into localized vibrations, enabling distinct sounds to come from specific areas of the screen while maintaining a slim profile. Since each emitter is separate, sound from one section does not interfere with nearby areas, resolving the crosstalk issue commonly seen in many display-speaker designs.

    Acoustic Optimization Techniques

    To manage these vibrations, the researchers incorporated frame structures that are finely tuned for shape, size, and material impedance. These frames help to contain acoustic energy in specific zones, enhance the frequency response, and reduce total harmonic distortion across a wider range. Long-term evaluations demonstrated consistent sound-pressure levels even with variations in input voltage and listening distance, indicating that the design is ready for commercial production.

    Potential for Market Integration

    Differing from past display-speaker hybrids, the POSTECH innovation preserves the slim design that is highly valued in OLED products while delivering accurate spatial audio. The successful demonstration of the 13-inch prototype points to an easy integration into current manufacturing processes for tablets, laptops, and car dashboards.

    Currently, the team has not provided any information regarding timelines or pricing. It remains unclear when, or if, this pixel-level sound technology will become available in everyday gadgets.
