Patent ID: 8270065

Claim:
A colored electrophoretic display, in an order of vertically receiving an incident light in an incident direction, comprising: a transparent substrate, a transparent conductive layer, a planar electrophoretic cell and a backplane substrate; the backplane substrate comprises: a first block reflective electrode, a second block reflective electrode and a third block reflective electrode, tiled in a planar arrangement perpendicular to the incident direction, adapted for band block reflecting the incident light passing through the transparent substrate and forming a first band block light in a first block band, a second band block light in a second block band, and third band block light in a third block band respectively; and a driving circuitry electrically connected to the transparent conductive layer, the first block reflective electrode, the second block reflective electrode and the third block reflective electrode, adapted for electrically charging the transparent conductive layer and each of the first block reflective electrode, the second block reflective electrode and the third block reflective electrode individually and driving conductive particles in the planar electrophoretic cell to move accordingly so as to allow the first band block light, the second band block light and the third band block light to irradiate out of the transparent substrate.
