E Ink Holdings started to produce 26" color ACeP (Advanced Color E-Paper) displays. The display supports a refresh rate that is lower than 3 seconds (similar to EIH's first 13" ACeP display).
ACeP displays look excellent - personally I was very impressed with the displays.
E Ink first-generation Triton color e-Paper displays never really reached commercialization as the performance was not good enough. The company also produces 3-color displays (Spectra displays).
