5 and 6 are perspective views illustrating the electronic paper display device of FIG. 4.

Referring to FIG. 5, the electronic paper display device 300 according to the present invention may be a capsule type electronic paper display device 300.

As shown, the capsule-type electronic paper display device 300 is a black microparticles 340 and white particles 330 to produce a transparent microcapsule contained in a colored dielectric fluid, and then mixed with a binder 350 Located between the upper and lower transparent electrodes 320 inscribed on the substrate 310, and when a positive voltage is applied, negatively charged ink particles may move to the surface to display the color of the particles.

In addition, when a negative voltage is applied, the ink particles move downward to see the color of the fluid, and in this way, the text or image is displayed.

Referring to FIG. 6, the electronic paper display device 400 according to the present invention may be a collision charging type electronic paper display device 400.

As shown, the structure of the collision charging type electronic paper display device 400 includes upper and lower substrates 460 and 410 formed of plastic or glass, and driving voltages of elements on the upper and lower substrates 460 and 410. Upper and lower electrodes 470 and 420 formed of transparent electrodes ITO, partition walls 430 separating cells from cells, and black positive charged particles 140 existing between the two electrodes. ) And white negative charged particles 450.

In the electronic paper display device having the above-described structure, when sufficient voltage is applied to the upper electrode 470 and the lower electrode 420, charged particles 430 and 440 charged according to the applied electrode polarity are attracted to each electrode. Goes.

For example, when a negative voltage is applied to the lower electrode 420 and a positive voltage is applied to the upper electrode 470, the black charged particles 440 positively charged by the coulomb force move toward the lower substrate 410. Then, the charged white charged particles 450 move toward the upper substrate 460.

Since the white charged particles 450 are located on the upper substrate 460 side, the white charged particles 450 appear to be white when viewed from the outside.

On the contrary, when the positive voltage is applied to the lower electrode 420 and the negative voltage is applied to the upper electrode 470, the charged white charged particles 450 move toward the lower substrate 410 and the positively charged black charged particles 440 moves toward the upper substrate 460 to be displayed in black.

Therefore, after applying a voltage so that all the cells appear white at first, only the desired cell is applied with the opposite voltage so that the cells appear black.

In the collision charging type electronic paper display device 400, two particles having different colors in each cell are charged positively by friction, and the other particles are negatively charged by friction.

7 and 8 are plan views illustrating various embodiments of a character input display device according to the present invention.
