OLED, I hear it's junk in the sunlight.

What's the word? If this is so than why put it in the incredible? (which I plan to get the day of).

Because AMOLED, or Active Matrix Organic LED, has a superb image quality while being lightweight and very power efficient - things a high-end mobile phone device need - as well as extremely cost-effective for manufacturers.

I thought OLEDs worked better in sunlight than LCDs.

You heard wrong.

LED emission colors are based on the physical size of the semiconductor used to build them. The problem is that LEDs don't come in any kind of material that will resonate well at 520 nanometers wavelengths (green spectra). There are some HUGE fundamental limits in semiconductor physics that make getting a good green LED almost impossible.

This is why the AMOLED display on the Nexus One has 50% green LEDs, 25% red and 25% blue instead of the 33%+33%+33% an equivalent LCD screen like the Motorola Droid has. They tried to compensate for the low output intensity of existing green AMOLEDs by simply using more of them ...

I see the sun in purple, personally.

To add to CellStudent's remarks, as I said earlier, the draw to AMOLED is economics of price, space, and weight. Just like 3G became a buzz word, so did AMOLED. It sounds cooler, therefore it must do the impossible, right?

Truth is, the sun is so intense that the only way to effectively, 100% prevent it from interfering with browsing LOLCATS on your way to work or school is to do it at night. Your exposure to sunlight is drastically reduced (though not eliminated).
