This article presents a multifunctional display based on photo-responsive perovskite light-emitting diodes (PeLEDs). The display can serve multiple functions, including touch control, ambient light sensing, and image sensing (such as fingerprint recognition), without the need for additional sensors. The key innovation lies in the integration of these functionalities into the pixel pixels of the display, which are made from photo-responsive PeLEDs. These LEDs exhibit high brightness and excellent photoresponsivity, allowing them to function as both light-emitting pixels and photodetectors. The display's performance is characterized by its electroluminescence and photovoltaic properties, demonstrating high efficiency and stability. The authors also demonstrate the display's practical applications, such as touch control, surface imaging, fingerprint recognition, and PPG monitoring. Additionally, the display can charge a supercapacitor, enhancing its self-sustaining capabilities. This multifunctional display offers a promising route for the development of ultra-thin, lightweight, and multifunctional displays, with potential applications in various electronic devices.This article presents a multifunctional display based on photo-responsive perovskite light-emitting diodes (PeLEDs).
