1. Technical Field
The present invention relates to an electrophoretic display module that employs an electrophoresis phenomenon, in which charged particles are moved by an applied voltage, for forming images, or an electrophoretic display device that employs the electrophoretic display module, and more particularly, to an electrophoretic display module having a specific structure, in which an electrophoretic laminate is fixed to a casing, and an electrophoretic display device that employs the electrophoretic display module.
2. Related Art
The invention will be described with reference to the accompanying drawings, wherein like numbers reference like elements.
FIG. 1 is a top plan view of a wrist watch used for an electrophoretic display (EPD) module according to a first embodiment.
FIG. 2 is a side cross sectional view of the EPD module according to the first embodiment.
Hereinafter, embodiments of the invention will be described. The following embodiments should be considered in descriptive sense only and not for purposes of limitation. Various changes in form and details may be made without departing from the spirit and scope of the invention.
An electrophoretic display (EPD) module includes an EPD laminate (or briefly referred to as laminate), conductive portions made of ITO layers which are located at both ends of the EPD laminate, a casing enclosing the EPD laminate, and retentive portions that are provided in the casing and retain the EPD laminate. The retentive portions contact and retain at least a part of the conductive portions to position the EPD laminate with respect to the casing.
According to the aforementioned structure, when the laminate is fixed to the casing, a stress is not applied to the laminate, and reliability of a sealing portion is improved so as to obtain the EPD module having high display quality and electrical characteristics.
