The DPT-RP1 offers a similar 13.3-inch display as its predecessor, but dramatically improves the resolution from 1200 x 1600 dots to 1650 x 2200 dots. The screen is a “non-slip” panel, which the company says will improve the experience of annotating documents with the included digital pen. The new design is also thinner, lighter, and faster than the previous version; Sony notes that the entire device is roughly as thick as a stack of 30 pages of paper.
I love e-paper and e-ink displays, but other than serving their purpose on e-reader devices, it seems the technology hasn’t progressed towards more generic use cases such as smartphones and tablets.
I bought into Sonys first e-paper products despite the price. Unfortunately the tech journals touted epaper energy efficiency but actual products were about the same as other technologies.
I’m still waiting for an affordable colour e-ink display. It seems that promising technologies get bought out and sat on (Pixel Qi) or languish in neglect (Qualcomm’s Mirasol). I guess they figure AMOLED is good enough. For smartphones and tablets, yes. For e-readers, not so much. I want an e-reader that can display static colour images and last for weeks between charges. I don’t give a toss about low-latency video (which is what pundits say has kept colour e-ink tech off the market). Where are the products to satisfy my use-case? I’m sure I’m not the only bloke in the world who wants this.
