Abstract Current display screens are typically only used for information display, but can have a range of different sensors integrated into them functions such as touch control, ambient light sensing and fingerprint sensing. Photo-responsive light-emitting diodes (LEDs), which respond to excitation, could be develop future ultra-thin large screen-to-body ratio screens. However, photo-response is difficult achieve with conventional technologies. Here, we report multifunctional that uses photo-responsive metal halide perovskite LEDs pixels. The LED simultaneously screen, sensor image (including drawing) without integrating any additional sensors. light-to-electricity conversion efficiency the pixels also allow act photovoltaic device charge equipment.
