Electroluminescent Light Sources TRIZ Cases

Shared island electrodes connect series light-emitting elements in-plane, raising external quantum efficiency while reducing layer count and cost.

Ferritin-coated quantum dots bonded by peptides remove QLED partitions, improving aperture ratio, light-emitting area, and brightness.

Selective metal-peptide binding places ferritin-encaged quantum dots on target pixel electrodes, avoiding partition walls and preserving aperture ratio.

High-boiling polar solvent inks enable inkjet-printed perovskite emissive layers with deeper red and green output for wider display color gamut.

A wet-coated graphene membrane interlayer improves electrode conductivity while blocking halogen and metal ion intrusion in photoelectric devices.

Multiple phosphorescent layers with tuned host and carrier-transport energies balance dopant emission and cut power use in displays and lighting.

A twisted fluorene-based hole-transport polymer enables wet-formed organic EL layers with higher durability, brightness, and longer working life.

A mixed organic-inorganic luminescent converter offsets self-absorption to widen spectral output and raise color rendering index.

Halide ions and a metal sulfide precursor keep quantum dots dispersed during coating, producing a more uniform layer with better luminescence.

A layered black matrix and reflective wall structure blocks stray light between pixels while preserving pattern accuracy and color purity.

Heating restores bank lyophobicity after UV/ozone or oxygen plasma cleaning, preventing ink intrusion while keeping recess wetting.

Heating after plasma or UV/ozone cleaning restores bank-surface lyophobicity, preventing ink intrusion during ink-jet patterning.

A light absorption layer with emission openings cuts surface reflections while preserving display contrast for higher-quality video.

A radial electric field between concentric electrodes self-aligns nano-sized LED elements, cutting misalignment and enabling dense, reliable pixels.

A switched bleeding circuit keeps a no-neutral lighting controller powered when OFF, while disconnecting during ON to avoid loss and inrush damage.

A water repellent layer overlapping the overcoat edge blocks moisture entry into the linear polarizer and protects foldable display yield.

Bank cut lines and conductive links keep adjacent upper transparent electrodes powered, reducing disconnection-driven pixel defects.

Asymmetric HOMO and LUMO level differences across transport and emission layers reduce carrier retention, improving OLED efficiency and lifespan.
