Abstract
An electronic paper display panel, including a first and second substrate; an electrophoresis layer arranged between the first and second substrates, the electrophoresis layer including black electrophoretic particle, white electrophoretic particle and at least one color electrophoretic particle; a first electrode layer arranged at a side of the first substrate facing the second substrate including multiple first electrodes; a second electrode layer arranged at a side of the second substrate facing the first substrate including multiple second electrodes; and a drive circuit; multiple pixel areas correspond multiple second electrodes; each first electrode includes a first sub-electrode and a second sub-electrode placed in same pixel area, which are insulated from each other, correspond to one second electrode and are connected with drive circuit, the first sub-electrode receives voltage signal different from voltage signal the second sub-electrode receives; the first electrode is common electrode and the second electrode is pixel electrode.
