High-resolution array devices via insulating pattern definition layer transferred by UV-adhesive stamp

Key Points

• The aim is to enhance the performance of high-resolution array devices by using a UV-adhesive stamp for insulating layer patterning.
• Applied a UV-adhesive stamp to improve solvent compatibility.
• Used insulating layer patterning to protect functional layers.
• Measured external quantum efficiency (EQE) and luminance of the device.
• The device maintained an EQE of 10%.
• Achieved a luminance of 40,000 cd m−2.
• Insulating patterning showed effectiveness in preventing physical damage.
