Electrowetting Displays

So it looks like Philips has come up with a 'paper replacement' display technology. The idea? Liquids trapped and zapped. Take a drop of ink and drop it in a tiny glass prison. When it's shocked with a small current it 'disappears'... another shock (presumably from a different direction or frequency) and it reappears.

ExtremeTech: Philips Spins Off 'Electrowetting' Display Venture

Sounds interesting, but...

1) It's still glass, and so far no one has delivered foldable glass.

2) They've got black and white, but so does eInk.

3) They say they can do color, but it seems like it should be an easy step from dropping in more colors of inks. So why haven't they?

3) There's no need for a backlight, but that probably means they've got a subtractive color system rather than an additive system. (Subtractive color reproduction almost always requires a fourth, black channel: RGB vs. CMYK.)

4) More color channels means bigger pixels. (The biggest hang up here is the lack of 'mixing' that you would see in print materials.) It would seems that surface tension would cause problems at the smaller and smaller sizes.

5) There would seems to be a lower limit to the size that this technology could reduce to. That limit would not likely approach that of AMLCDs or OLEDs.

Nonetheless, it will be interesting to see what this new venture does.

Corning's new LCD glass

It looks like Corning has made a great advance in getting the LCD manufacturing process a little more green. They've replaced all of the heavy metals that are used in the manufacture of the LCD display panels. Their new Eagle XG product looks like a real advance for the industry as a whole.

Corning's press release was posted to a number of blogs and other web sites:

What's in *your* Monitor?

Over at Slashdot, they linked to a great little 7 page primer on what makes up CRT and LCD displays. Get the low down on AMLCD (Active Matrix Liquid Crystal Displays) and find out what TFT really means.

Surprise! LCD Market Grows

Just in case you hadn't caught on to the trend, the market for LCD Monitors continues to grow, year over year, by 36%.

Of course, it's the low end of the market that's growing. The 17" and 19" monitors are definitely hot hot hot this season, and will continue to be the leaders for quite a while.

The Competing Display Technologies

Check out this cool article discussing the current four main competing display technologies by DisplayMate writer Raymond Soneira. It is the second in a four part article set on the topic of comparing the four technologies, LCD, plasma, DLP rear-projection and CRT with regards to gray-scale and color accuracy.
