Residual and contact patterns keep closely spaced LED electrodes insulated from particles, enabling higher LED density without short circuits.
Inclined reflective electrodes replace separate LED walls, simplifying fabrication while improving light extraction and element packing.
Inclined hole electrodes simplify LED array fabrication while improving element alignment, reflective light extraction, and signal stability.
Fluorine- or silicon-based surfactants lower ink surface tension to improve spreading and light-emitting element dispersibility in printed displays.
Grooves and exposed contact portions guide light emitting elements between electrodes, improving alignment uniformity, connection reliability, and luminance.
A Hansen-parameter solvent keeps light-emitting elements dispersed during printing, reducing sticking and improving sub-pixel luminance uniformity.
Grooves in an insulating layer and electric-field self-alignment place light emitting elements uniformly between electrodes to improve luminance.
Fluorine- or silicon-based surfactants lower ink surface tension for even spreading, element alignment, and more uniform display luminance.
A comb-like holder transfers nano-objects in vacuum to limit contamination, preserve crystallinity, and improve substrate interface control.
A vacuum transfer process uses a comb-shaped support to place carbon nanotubes cleanly and precisely, improving interface control and reproducibility.
Solvent tuning with Hansen parameters keeps light-emitting elements dispersed during printing, improving alignment and sub-pixel luminance.
Sequential cantilever loading and unloading addresses random deposition by improving nanostructure placement and avoiding collisions.
