In this paper, The OTFT backplane with bottom contact structure on plastic substrate using combined process will be discussed. The active size of backplane was 6″; in diagonal direction and 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 were made by ink jet printing combining plasma treatment. Finally, The EPD panel successfully displayed test patterns.
