A new four-pigment electrophoretic display has been developed, delivering a color gamut volume of >10,000 dE3 without a front light and >40,000 dE3 when front-lit in an update time of 500ms. This order-of-magnitude speed improvement over prior multipigment displays enables full-color e-reader devices to be made without color filters.
