Pixel‑Based Local Sound OLED - Coggle Diagram
Pixel‑Based Local Sound OLED
Evolution
Pixel-Based Local Sound OLED is a revolutionary display technology developed by POSTECH (Pohang University of Science and Technology, South Korea). First announced in 2024, it integrates piezoelectric actuators directly into each OLED pixel, allowing the screen to produce sound without the need for traditional speakers.
This innovation builds upon OLED’s natural thinness and flexibility, aiming to create fully immersive audio-visual experiences.
Uses
Smartphones & Tablets: Allows immersive media consumption with spatial audio directly from the screen.
TVs and Monitors: Eliminates external speakers and enables pixel-precise sound projection.
Virtual Reality (VR): Enhances immersion with localized 3D sound directly from displays.
Automotive Displays: Enables different sound sources for drivers and passengers from the same screen.
Limitations
Prototype Stage: Still under testing, not available in consumer products.
Manufacturing Complexity: Integration of piezo elements could increase production cost.
Scalability: Needs further development for large screens like TVs.
Key Features
Energy Efficient
Uses minimal power for localized sound emission.
Lightweight & Thin
Maintains OLED’s slim profile.
No External Speakers Needed
Sound comes directly from the screen surface.
Integrated Piezo Actuators
Ultra-thin components embedded under the OLED layer.
Pixel-Level Sound
Each pixel acts as an individual sound source.
Performance
High Precision Sound Localization: Each pixel can emit sound, allowing precise spatial audio.
No Crosstalk: Special design avoids interference between neighboring pixels.
Stable Output: Consistent sound pressure and low distortion over varying conditions.
Synchronized Audio-Visual: Excellent syncing between image and sound, improving user immersion.
