Abstract

The invention provides an electrophoretic display device, which includes an electronic ink layer, a passive matrix substrate and a conductive layer. The passive matrix substrate has an electrode surface, and the electrode surface also has a plurality of electrodes. The conductive layer has a predetermined shape and is arranged between the electronic ink layer and the electrode surface of the passive matrix substrate. The electrophoretic display device of the present invention can be applied to information transmission media such as electronic advertising billboards, smart cards, and electronic tags that need to display certain specific images.

Description

technical field [0001] The present invention relates to a flat display device, and in particular to an electrophoretic display device. Background technique [0002] Traditional electronic advertising billboards, smart cards (smart cards) and electronic tags all use liquid crystal displays (Liquid Crystal Display, LCD) to display certain specific images, so that specific information can be conveyed to the people. However, smart cards and electronic tags using liquid crystal display devices not only consume power, but are also inflexible, thus causing various restrictions and inconveniences in use. In addition, electronic advertising billboards using liquid crystal display devices not only consume power, but also the images displayed on such electronic advertising billboards cannot be clearly recognized in sunlight. Contents of the invention [0003] The invention provides an electrophoretic display device, which is suitable for use in information transmission media such a...
