Ultra-Thin LEDs Comparable to Wallpaper

Scientists have developed a paper-thin quantum dot LED (QLED) that emits a full-spectrum, sunlike glow, marking a significant advancement for the lighting industry. Engineered with red, yellow-green, and blue quantum dots, the device delivers high color fidelity (CRI >92) and a warm white output tailored to reduce blue light exposure — key for applications prioritizing visual comfort, such as residential, hospitality, and workplace environments.

With its ultra-thin profile, comparable to wallpaper, the QLED presents new form factor possibilities for architectural lighting and surface-integrated luminaires.

The device’s ability to operate efficiently at low voltages — some versions achieving peak brightness at just 8 volts — adds further appeal for energy-conscious lighting manufacturers. The thin quantum dot layer also allows for more compact fixture designs without compromising light quality.

Researchers noted the QLED’s performance exceeds brightness standards for monitor backlighting, positioning the technology as a candidate for high-end display and human-centric lighting systems.
