Abstract
A transflective electrophoretic display and a method for manufacturing the same are proposed. The transflective electrophoretic display including a top substrate and a bottom substrate, multiple separating walls disposed between the top and bottom substrates, a transflective film, and an electrophoretic display medium, can be designed to display colors by using multicolor electrophoretic display media or color filters. The display can be viewed with or without ambient light by adopting a backlight module, as well as to improve the overall display quality.
