This review outlines problems and progress in development of solution‐processed organic light‐emitting diodes (SOLEDs) in industry and academia. Solution processing has several advantages such as low consumption of materials, low‐cost processing, and large‐area manufacturing. However, use of a solution process entails complications, such as the need for solvent resistivity and solution‐processable materials, and yields SOLEDs that have limited luminous efficiency, severe roll‐off characteristics, and short lifetime compared to OLEDs fabricated using thermal evaporation. These demerits impede production of practical SOLED displays. This review outlines the industrial demands for commercial SOLEDs and the current status of SOLED development in industries and academia, and presents research guidelines for the development of SOLEDs that have high efficiency, long lifetime, and good processability to achieve commercialization.

After removing liquid crystals (LCs) using hexane cleansing solution, polymer network (PN) structure of polymer stabilized blue phase (PSBP) was analyzed. PN type had different shape in the surface region (nearby glass) and intermediate region. Directly measured PN structure and theoretical polymer line defect on the cubic symmetry were compared. Moreover, analysis of different kind of LC and monomer, PN appeared in membrane state.

We propose a lightpath routirrg reconfiguratiorz algorithm rniriiniizing the number of OXCs. We present the exuct problem descriplion in ILP formulation arid show several examples. From experiniental results, we found that considerable nuniber of OXCs can be saved.
