I was reading the TechRadar article and was getting very confused since the author seems to have little knowledge of any ereaders other than Amazon's products. And then there were items that read as sheer bunkum. Anyone able to translate the first sentence of the following paragraph into a comprehensible form?
Quote:
The 4000-color capabilities come by way of a filter co-developed with E Ink that uses Nitride LEDs to assign pixel-level colors. This is in contrast to the color E Ink Gallery 3 display on the new Remarkable Pro, which uses colored particles to generate on-screen colors.

It's a physical technology where tiny black and white balls are energized to turn to the black or white side to generate an image.

It turns out that the oxide backplane and Nitride LEDs were also crucial to maintaining the contrast. "The [color] filter pulls down the contrast ratio a little bit," Kieth told me, "and we were able to use the backplane and the LEDS to boost the contrast back up. If we hadn't done that, it would dramatically make the reading experience worse."

This one, to me, translates as the Nitride LEDs allow us a brighter frontlight to compensate for the Kaleido 3 screen's colour filter.
Quote:
Keith told me the Nitride LEDs are more color-friendly than the white LEDs used on previous Kindles. "Then we use these coatings to focus the light through individual pixels instead of mixing colors together. The Nitride LEDS are key to that but it's also with these coatings that they put through the display stack that enables the focus to happen." Put another way, Keith explained, it's focusing the light through individual pixels of color instead of just a spray that mixes color together.

Sorry but that paragraph reads as "if you can't dazzle them with brilliance, baffle them with bullshit". They are focusing coloured LEDs through each individual pixel on an eInk screen? On displays which are notorious for being opaque and so need a front light, Amazon is shining light through the display? As it is, I'm trying to visualize a light guide that is able to deliver red, green and blue light to the individual colour filters.
