Electrophoretic display (EPD) manufacturing method for e.g. electronic newspaper production includes directly coating organic thin film transistor layers on the side of the EPD module supporting the pixel electrodes

摘要

The method includes providing an electrophoretic display (EPD) module (10) with multiple EPD units on a common glass substrate. Each EPD unit has a cell having optical characteristics that can be capacitively switched. Multiple pixel electrodes (21) are coated on a side of the EPD module. Organic thin film transistor (OTFT) control circuit (20) is prepared by directly coating a number of OTFT layers on the side of the EPD module supporting the pixel electrodes. OTFT layers include a drain electrode (24), a source electrode (26), a gate electrode (32), and an organic semiconductor layer (28). An independent claim is included for the electrophoretic display including an organic thin film transistor.
