The present invention relates to a metal electrophoretic display device, in particular a metal electrophoretic display device that can prevent the flexible film from being lifted or separated from the electrophoretic display panel by preventing the adhesion between the flexible film and the electrophoretic display panel is lowered. It is about.
In general, an electrophoretic display device is an image display device using a phenomenon in which colloidal particles move to either polarity when a pair of electrodes to which voltage is applied is immersed in a colloidal solution. A wide viewing angle, high reflectance, and low consumption without using a backlight Since it has characteristics, such as an electric power, it is attracting attention as an electronic device, such as an electric paper.
The electrophoretic display device has a structure in which an electrophoretic layer is interposed between two substrates, one of the two substrates is made of a transparent substrate, and the other is composed of an array substrate on which a driving element is formed, thereby reflecting input light. The image can be displayed in the reflective mode.

The present invention is to solve the above problems, by uniformly applying the adhesive resin on the flexible film, the adhesive strength of the partial region between the flexible film and the electrophoretic display panel is lowered to lift or tear the flexible film from the electrophoretic display panel. An object of the present invention is to provide an electrophoretic display device capable of preventing the same.
In order to achieve the above object, the electrophoretic display device according to the present invention comprises an electrophoretic display panel for implementing an image as the particles move as the electric field is applied; Flexible films respectively attached to pads of the electrophoretic display panel; A second wiring formed on the flexible film and connected to the first wiring of the electrophoretic display panel; At least one reinforcement pattern formed on the flexible film to reinforce the flexible film; A plurality of grooves formed in the reinforcement pattern; And an adhesive resin and conductive material applied between the flexible film and the electrophoretic display panel to attach the flexible film to the electrophoretic display panel and to electrically conduct the first wiring of the electrophoretic display panel and the second wiring of the flexible film. Consists of particles, the grooves are characterized in that the adhesive resin and conductive particles are applied.
The flexible film is formed with an SR region coated with a solder resist covering the second wiring, and the groove extends to the SR region.
In the present invention, an anisotropic conductive film for attaching the flexible film to the electrophoretic display panel is applied to the adhesive resin and the conductive particles in the grooves formed in the reinforcement pattern of the flexible film, thereby preventing a decrease in adhesion force due to the reinforcement pattern.

Hereinafter, an electrophoretic display device according to the present invention will be described in detail with reference to the accompanying drawings.
In the present invention, by patterning the reinforcing pattern formed on the flexible film to form a region in which the adhesive resin and the conductive particles of the anisotropic conductive film is introduced to improve the adhesion by securing the spreading region of the adhesive resin and the conductive particles of the anisotropic conductive film.
In the conventional metal electrophoretic display device, the adhesive resin and the conductive particles of the anisotropic conductive film do not spread well in the adhesive region because the temperature of the electrophoretic display panel and the flexible film compressed by the thermal conductivity of the metal decreases rapidly. This is because the spreading time of the resin and the conductive particles is shortened.
In the present invention, by spreading the adhesive resin and the conductive particles of the conductive film in the adhesive region of the electrophoretic display panel in a short time, it is possible to prevent the flexible film from lifting or tearing off the electrophoretic display panel in the metal electrophoretic display device. .
