Ironically, LG says that it had no reason to steal Samsung's OLED technology considering that both firms' OLED displays work differently. Still, Samsung calls this a "grave crime" and wants LG to take responsibility for the leak by admitting their actions. OLED panels, which are thinner and offer more vivid pictures than regular LCD display panels, are in heavy demand. 6 other suspects in the case are current or former Samsung Mobile employees.
