Long-time Japanese rivals Sony and Panasonic Corp. are working together to develop next-generation TV panels called OLEDs in a reversal of decades of rivalry as they try to catch up with South Korea's Samsung Electronics. The companies said in a joint statement Monday, June 25, 2012, they will share core technologies to develop OLED panels. They are aiming for low-cost mass production by 2013.
