Did you miss "Mad Money" on CNBC? If so, here are some of Jim Cramer's top takeaways.

The OLED revolution is finally here, Cramer told viewers. For you and me, that means brighter, thinner and more power-efficient displays for our smart phones and devices. But for investors, that means it's time to buy Universal Display Corp. (OLED) , a stock that's already up 108% for the year. (OLED is short for organic light emitting diodes.)

Cramer explained that Universal Display is at the heart of OLED technology, with proprietary technology that it licenses to manufacturers. The company was bolstered in 2015 by rumors that Apple is looking to upgrade its iPhones to OLED, and shares surged again in 2016 after Applied Materials (AMAT) reported receiving a $700 million order for equipment to manufacture OLED displays.

But those hopes were dashed earlier this year as the company struggled to make its margins, a situation that quickly resolved itself. When Universal Display last reported, it delivered a 22-cents-a-share earnings beat on an 87% spike in revenues with strong full-year guidance to boot.

Cramer said with so many uses for OLED and its superior technology, coupled with increased manufacturing capabilities, it's worth paying 46 times earnings for Universal Display, although he'd still prefer to buy the stock on any weakness.

OLED fell 0.1% to $116.80 on Tuesday in early morning trading.
