South Korean electronic giants Samsung and LG have agreed to end a year-long battle over display technology patents that spawned a series of lawsuits. LG Display and Samsung Display—respectively the world’s top and number two display panel manufacturers—had locked horns over a number of patents for next-generation display technologies for TVs and other devices. The two firms had accused each other of stealing liquid-crystal display (LCD) and organic light-emitting diode (OLED) technology and key engineers. LG claimed last year that key Samsung products, including its global hit Galaxy S smart-phones, violated LG’s OLED technology and sought financial damages and injunction against five Samsung devices.
