Abstract
An electrophoretic display device includes an electrophoretic display module, and a polymer light emitting diode (PLED) module. The polymer light emitting diode (PLED) module is over the electrophoretic display module, and is aligned with and is attached to the electrophoretic display module. In a dark environment, the polymer light emitting diode (PLED) module can emit light to supplement the insufficient ambient light, so that the users may observe the information or pattern displayed by the electrophoretic display device. The electrophoretic display device can be a flexible electrophoretic display device.
