DISPLAY PANEL STRUCTURE AND DRIVING METHOD THEREFOR

The present invention relates to: a display panel structure consisting of a composite material phase, capable of implementing four full colors and changing to a transmission mode; and a driving method therefor enabling changing to a reflection mode, a shielding mode, and the transmission mode, the display panel structure comprising: an upper substrate; a lower substrate; an upper electrode arranged on one surface of the upper substrate; a lower electrode arranged on one surface of the lower substrate; and a partition which is formed between the upper substrate and the lower substrate and which defines a unit pixel region, wherein the unit pixel region includes a plurality of first particles displaying a first color, a plurality of second particles displaying a second color, a plurality of third particles displaying a third color, and a plurality of fourth particles displaying a fourth color, each of the plurality of particles being spread in a fluid, each of the plurality of first, second, third, and fourth particles has both a positive charge and a negative charge in a single particle, the charge amount of the positive charge differs from the charge amount of the negative charge, and the plurality of first, second, third, and fourth particles are vertically and horizontally arranged at predetermined intervals from the upper electrode to the lower electrode so as to implement the transmission mode.
