Forget PR and work on the usability and SEO factors first.
I checked your site and found the following areas that need attention.
.
1/ Using firefox the layout of the Google Ads is overlaying the adjacent text.
2/ Lose the ALL UPPER CASE TITLE AS IT LOOKS REALLY CRAPPY AND IS WAY TOO LONG
3/ NO Adsense Compliant policy
4/ Use the Keyword OLED a little less (well actually a lot less) , most search engines do NOT like keywords that are used so many times that it looks SPAMMY.
Optimum density percentages for a given keyword is between 3-5%
On your frontpage "oled" is used 222 times for a density of 10.31%
