Compact Pixel Architectures Enabled by Frequency‐Modulated Color‐Tunable AC‐Driven Electroluminescent Devices (Advanced Optical Materials 1/2026)

Compact Pixel Architecture via ACEL The frontispiece shows a frequency-modulated, AC-driven quantum-dot electroluminescent pixel comprising tandem RGB stacks separated by a charge-buffer layer. Varying the drive frequency redistributes charge between the top and bottom stacks to yield smooth, reversible color tuning. This compact architecture approaches the DCI-P3 color gamut and simplifies full-color, ultra-high-resolution displays. More details can be found in the Research Article by, as reported by Shuai Chang and co-workers (DOI: 10.1002/adom.202502689).
