Role of the Recombination Zone in Organic Light‐Emitting Devices
Advanced Materials, EarlyView.This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Simultaneous Emission AC-OLED Pixel Circuit for Extended Lifetime of OLED Display
IEEE Journal of the Electron Devices Society, 2018 This paper demonstrates a pixel circuit of seven thin film transistors (TFTs) and two capacitors that drives an AC driven OLED (AC-OLED) at a simultaneous emission scheme. Because the AC-OLED is composed of two OLED units connected in opposite directions,

Acta Crystallographica Section E Structure Reports Online, 2011 The molecule of the title pyridine derivative, C(5)H(6)N(2)O, shows approximate C(s) symmetry. Intra-cyclic angles cover the range 118.34 (10)-123.11 (10)°. In the crystal, O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonds connect the mol-ecules into double layers perpendicular to the a axis. The shortest centroid-centroid distance between two π-systems is 3.8887 (

Perspective: OLED Displays Singing with the Blues
Advanced Materials, EarlyView.While blue pixels consume approximately 50% of the energy of OLED display front planes, in the 25 years since their invention, 100% internal efficiency triplet‐controlled phosphorescent OLEDs have not met the stability standards necessary for their adoption.

Resistive Heating for Inducing Localized Crystal Growth in Organic Thin Film Devices
Advanced Materials Technologies, EarlyView.Rubrene thin films are promising for organic optoelectronics due to high hole mobility. However, uncontrolled crystallization and grain boundaries from standard thermal processing hinder lateral device scalability. This work presents femtosecond‐laser micromachining and patterned resistive heating to induce localized, deterministic crystallization ...

Advanced Materials Technologies, EarlyView.This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control
