Full-Color Video e-Paper Based on Oxide TFT
Description:
In order to break the bottleneck of traditional e-paper in playing color video information content. A new full color video e-paper based on electrowetting display (EWD) technology and driven by oxide TFT is proposed. By optimizing the panel design and process conditions, the 10.3 inch prototype with 186PPI resolution was successfully developed, which combines the advantages of oxide backplate with electrowetting display (EWD ) technology . We successfully drives the stacked EWD panels by the top gate IGZO backplate processed with 12 masks . By adopting this structure, the device mobility is 17.2 cm2/Vs with aperture ratio of pixel 90.3%, reflectivity of single color mod is 38.5%, reflectivity of full color mod is 12%, and refresh rate up to 60HZ, which supports the playing of regular video contents.
