Description
Technical field
The invention relates to that a kind of plane shows the fluorescent screen, and particularly relevant for a kind of electrophoresis display structure.
Background technology
(Electrophoretic Dispaly, EPD) technology is the technology that most possibly realizes the electronic paper industrialization owing to combine the advantage of plain paper and electronic console to electrophoresis showed.Electrophoretic techniques has several big advantages.The one, energy consumption is low.Owing to have bistability, after power supply is closed, still on display, image kept several days or some months.The 2nd, the display that electrophoretic techniques is produced belongs to reflection-type, therefore has good daylight readability, equally also can in front of the light of face or side combine, be used for dark surrounds.The 3rd, have the potentiality of low production cost, because this technology does not need strict encapsulation, and the employing solution processing techniques is feasible as printing.The 4th, electrophoretic display device (EPD) is a characteristic with form factor flexibly, allows that they are fabricated on plastics, metal or the glass surface, so it is the optimal selection of flexible display technologies.It is shown one's talent from numerous display techniques at present, becomes one of pliability electronic display technology that has development potentiality.
Present color electrophoretic display has comprised a thin-film transistor array base-plate, and an electrophoretic display thin film is positioned on the thin-film transistor array base-plate, and a colored filter is positioned on the electrophoretic display thin film.Be to bond between thin-film transistor array base-plate, electrophoretic display thin film and colored filter by colored adhesive coating.Colored adhesive coating generally is being with mazarine, has absorption not by the subreflexive light of particulate in the electrophoretic display thin film.Need accurate applying between colored filter and thin-film transistor array base-plate, so colored filter and thin-film transistor array base-plate are equipped with alignment mark.But the opacity of colored adhesive coating has had a strong impact on the contraposition between colored filter and thin-film transistor array base-plate.For this reason, need badly and want a solution to improve the problems referred to above.
Summary of the invention
