Biing-seng Wu has spent most of his career developing tiny chips that tell pixels on flat-screen displays how and when to light up.
Twenty-five years ago, he teamed up with his brother Jordan Wu to develop such chips for screens. Today, products from their company, Himax Technologies, can be found in everything from Lamborghinis to smartwatches, and have turned the duo into billionaires.
The brothers own 24% of Himax, whose U.S.-listed shares have more than doubled in value this year. Their stake in the Tainan, Taiwan-based firm, as well as proceeds from dividends and stock sales, give them a combined $1 billion net worth, according to the Bloomberg Billionaires Index, which is valuing them for the first time.
