Display panel structure and driving method thereof

The present invention relates to a display panel structure made of a composite material and capable of realizing a full color of four colors and a variable transmission mode, a panel structure capable of realizing conversion of a reflection mode, a shielding mode and a transmission mode, and a driving method thereof, and is characterized by comprising: an upper substrate; a lower substrate; an upper electrode disposed on one side surface of the upper substrate; a lower electrode disposed on one side surface of the lower substrate; and a partition wall for defining a unit lattice region formed between the upper substrate and the lower substrate, each unit lattice region comprises a plurality of first particles presenting a first color, a plurality of second particles presenting a second color, a plurality of third particles presenting a third color and a plurality of fourth particles presenting a fourth color, which are dispersed in the fluid; the first particles, the second particles, the third particles, and
