The present invention relates to an improved EPD which comprises both the
traditional up/down switching and the in-plane switching modes. The
monochrome EPDs of the present invention are capable of displaying
highlight color of choice which is different from the text. Furthermore,
the full color EPDs of the present invention are capable of displaying
high contrast images of high color saturation. Both high quality black
and white states are possible in the full color displays of the present
invention. The EPDs of the present invention do not need complex
circuitry design, and are compatible with low cost and high yield
roll-to-roll manufacturing processes.
