Abstract
The low-cost pixel matrix is one of the largest challenge in the area of organic light emitting displays (OLEDs), lowering manufacturing costs of OLEDs further must be a concerted effort to allow for larger market shares. In this work, electrochemical polymerization (EP) technology is introduced to directly and efficiently deposit red, yellow green and blue (RGB) EP films for passive matrix polymer light-emitting displays (PMPLEDs). After optimizing the polymerized condition, RGB EP films with clear boundary and smooth morphology are obtained on 1.7-inch PMPLED backplane. And their corresponding PMPLEDs with optimized device structure perform nice images without dead line and work well under the driving of external chips. EP technology owning the simple operation, precise positioning for the fabrication of patterned films would significantly reduce the production cost of polymer light-emitting displays.
