Study on Precision and Uniformity Evaluation Method of PEDOT/PSS Ink-jet Print Film

PEDOT/PSS has an excellent performance in the electronic components and ink jet print has been used widely printed electronics. But the film quality of PEDOT/PSS produced by ink jet printers can be limited by many parameters and is very difficult to evaluate accurately. In this paper, we propose uniformity and precision as the key indicators and combine image processing method in to the evaluation methods. First we analyses the characteristic and limitation of the ink jet printer, and use image processing methods to evaluate the experimental data. From the result it demonstrates this new method is feasible, and can get more detail. And it can apply in the future dedicated ink jet printer study and quality detection.
