Samsung Display Co., the world\'s biggest display maker, has decided to drop a patent suit against LG Electronics Co. over liquid-crystal display technologies, paving the way for both sides to end a long-running legal battle, industry sources said Wednesday. The two display giants have been embroiled in a patent tussle over organic light-emitting diode (OLED) and LCD technologies that broke out on the heels of a police investigation into an alleged leak of technologies from Samsung Display to LG Display last year.
