There are some rumors this morning about Samsung SDI that it will be spending over $500 million USD to boost production of next-generation OLED displays to six times its current level by mid-2009.

This latest move comes as panel makers try to get bigger shares of the growing market for OLED displays, which offer better contrast ratio, slimmer designs and better energy efficiency than current LCD or plasma displays.

Currently, however, production costs are still high, too high to make OLED TVs available to the masses.

Using 2-inch screens as a basis, the new investment should raise capacity from 1.5 million units a month to over 9 million by mid-2009.
