Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of OLED technology developer Universal Display (Nasdaq: PANL) are shining bright today, jumping as much as 15.8% on heavy volume.

So what: Korean electronics giant LG Electronics just announced an OLED-equipped smartphone, set for a European debut in mid-September. Not counting the brief appearance of OLED screens on the HTC Droid Incredible last year, the LG Optimus Sol becomes the only big-screen OLED smartphone on the market not stamped with the Samsung brand.

Now what: LG Mobile CEO Jong-Seok Park claims that the new model will "stand out from its competitors as the most affordable 1 GHz Android smartphone with an AMOLED display," though he didn't announce any kind of pricing. This news of a possible high-volume addition to the OLED family overpowered the potentially damaging assertion that Apple will hold off on OLED-equipped phones and TV sets until global manufacturing capacity on the technology catches up with Apple's high-volume demands. Then again, that's been obvious for a while, hasn't it?
