Sub-Pixel Structure and Pixel Structure of Color Electrophoretic Display

A pixel structure of color electrophoretic display comprising:

• a plurality of first sub-pixel structures, and each of the first sub-pixel structures comprising:
• a first driving unit;
• a first display unit disposed on the first driving unit, the first display unit comprising a plurality of first charged particles, a plurality of second charged particles and a plurality of third charged particles, diameters of the first charged particles being greater than diameters of the second charged particles and the third charged particles, the first charged particles and the second charged particles having the same electrical property, the first charged particles and the third charged particles having opposite electrical properties, and the first charged particles, the second charged particles and the third charged particles having different colors;
• and
• a first transparent electrode disposed on the first display unit, wherein the first transparent electrode is used as a common electrode for the first sub-pixel structures.
