LG and Samsung are the only two companies that create plastic-based OLED smartwatch display panels, which gives them a huge advantage over other display makers. OLED displays have become the smartwatch industry standard, as opposed to the smartphone market, where LCD displays are by far the most common type of panels.
Looking into the future, DisplaySearch believes that only Samsung can compete with LG's smartwatch display offerings, with Samsung believed to join LG as a display supplier for the next-generation Apple Watch.
