I think when 300 dpi can be realized in production that 150 ppi can be shipped and will finally be high enough for many users.
The controller would be able to provide text only areas at higher resolution and images with good color. I suspect this is less than a year away. The carta technology merged with Triton will make it the screen of the future. |
I am not sure that Triton - a color filter - will be the future. Not only the enormous loss of resolution is a concern, but the technology had been there for many years yet it was not made into mass market products, and this time the problem is not cost: it is with the disappointing effect. A filter causes attenuation on displays which are already not of coal on snow contrast.
I am convinced that next is colour, but I bet on the ACEP, the "Advanced Color ePaper" - having in a single dot (cell, pixel) the pigments (like Cyan, Magenta, Yellow, blacK) required for subtractive colour synthesis. Of course, we have to wait for it to became a viable mass production possibility.

The text remains hi-res because the filters multiply on black (dark grey), but applied on the whitey background the filter should make it become a darker net of coloured spots - your background, normally white but now under a grid of Red-Green-Blue-Transparent inks, would become a mixture of colours... It works with lights (R+G+B = W), but it is not natural with inks.
You need, as you have now, elements that go White-to-Cyan, White-to-Magenta, White-to-Yellow, White-to-Black, and possibly in the same cell. This simulates print. Advanced Color ePaper is implemented around this.
