Pentile – the downfall of Galaxy S?

I’ve been trying to decide for months now whether I want to get the HTC Evo or Samsung Epic. One of the biggest factors, the screen, is carrying me in the opposite way from what most would expect.  The Epic’s screen is being described as: “knockout”1, “Colors are as crisp as can be” 2, and “most important characteristics”3.  One really has to research more deeply before this term comes up: “Pentile”.

The rest of this editorial is a rehashing and commentary on the Ars Technica article on the topic.

If you examine the Evo and Epic screens side-by-side, particularly displaying text, you might notice that the Evo looks a little better.  The lines are straight and sharper; the Epic has an odd fuzziness at the edges.  It’s almost like you’re looking at one shadow-mask screen and the other one aperture-grille (I know it’s not a great comparison because of pixel technology, but it’s the best visualization I can come up with).

It turns out that while the Evo’s screen is made of the standard array RGB pixels, the Epic’s screen is made of an array of pixels, alternating between a double-width red with green and double-width blue with green.  What this comes down to is that some colors can’t be achieved within just one pixel and have to use two.  This is why letters don’t look as sharp.

So, while the Epic’s screen is great for playing games and watching movies.  For text-based activities, I think the Evo’s is the better screen.

Sprint Evo: first impressions

I had a chance to briefly go one-on-one with the Evo. Here is what I learned:

– 4.3 inches (diagonally) is a lot of real estate. The phone nearly filled my field of vision.

– The phone is big. Too big to type with one finger, even when held vertically. However, I did a bit of two-handed typing in portrait mode and it was very pleasant. I’ve never been a landscape typer, so this was a neat find.

– The Evo is speedier than the Hero, obviously due to the processor and memory bump. Sadly, that doesn’t hold when actively using and switching between applications. In particular, I found that two of my pain points on the Hero – dialing and texting – are still painfully slow on the Evo. Much faster but not nearly instant like they should be. The dialer lag on HTC’s Sense interface is the primary reason I want a vanilla Android device.

– On the other hand, some activities that used to slow the Hero to a halt, like using Google Navigation, are now nice and speedy.

That’s all for now. If I get the Evo I’ll post a more thorough review.
