Practical printing method of solution processed OTFT backplane for Electrophoretic Display

摘要

In this paper, The OTFT backplane with bottom contact structure on plastic substrate using all solution processes will be discussed. The backplane consisted of 192×150 pixels, containing 1 OTFT and 1 capacitance in each pixel. Each layer of OTFT was used combining process to overcome the problem of printing technique. The gate electrodes were fabricated by screen printing with wet etching. The source drain electrodes and OSC were made by ink jet printing. Finally, The EPD panel successfully displayed test patterns.
