Graphical Abstract

A flexible high-resolution micro-LED display device has been developed through the ingenious combination of inorganic micro-LEDs and organic materials with extraordinary performance.

Abstract

Computer vision techniques are real-time, immersive, and perceptual human-computer interaction technology. Excellent display effect, dynamic surface flexibility, and safe bio-adhesion are essential for various human–computer interaction applications, such as metaverse interfaces, skin-like sensors, and optoelectronic medical devices. However, realizing the flexible matching of inorganic optoelectronic devices and organisms remains a grand challenge for current display technologies. Here, we proposed a novel strategy by combining the optoelectronic advantages of inorganic micro light emitting diode (micro-LED) display and the extraordinary mechanical/biological compatibility of organic materials to overcome this challenge. A highly elastic (greater than 2000% strain), highly transparent (94% visible light transmittance), biocompatible conductive hydrogel composite electrode layer was fabricated. For the first time, we realized the on-chip electrical interconnection of 4900 LED units to form a blue-green light display patch with high resolution (264 PPI), low power consumption (4.4 mW) and adaptive surface attachment. This work demonstrates an integrated scheme and potential applications of flexible high-resolution microdisplays, such as wearable full-color micro-LED smart curved display devices and conformable biomedical monitoring systems.
