Patent ID: 7777939

Claim:
A method of manufacturing an electrophoretic display (EPD) having an organic thin film transistor (OTFT) control circuit, the method comprising: providing an EPD module comprising a plurality of EPD units on a common substrate, wherein each of the EPD units includes a cell having optical characteristic that can be capacitively switched; coating a plurality of pixel electrodes on a side of the EPD module; and preparing the OTFT control circuit by directly coating a plurality of OTFT layers of the side of the EPD module supporting the pixel electrodes, wherein the preparing of the OTFT control circuit comprises: applying a first insulating layer on at least one of the pixel electrodes, wherein the first insulating layer has a through hole; applying a drain electrode, a source electrode, and an organic semiconductor layer on the first insulating layer, wherein the organic semiconductor layer is between the drain electrode and the source electrode, and wherein at least one of the drain electrode or the source electrode is connected to the at least one of the pixel electrodes via the through hole; applying a second insulating layer on the drain electrode, the source electrode, and the organic semiconductor layer; and applying a gate electrode on the second insulating layer.
