Foldable displays feature in Korean patent landscape
According to the Korean Intellectual Property Office on August 19, over the last six years, a total of 276 patents related to foldable panels were applied for in Korea, with 210 patents filed in the last three years.
LG Display has applied for the highest number of patents (94), followed by its rival Samsung Display (80), Samsung Electronics (23) and LG Electronics (17) over the last six years, the nation’s intellectual property agency said.
Foldable displays are expected to bring novelty to the stagnant hardware design of smartphones, enabling differentiated features, such as screen size changes from a smartphone size to a tablet size when unfolded. But display durability upon repetitive folding/unfolding cycles is key and many patents applied by the Korean tech giants are related to the durability of future foldable panels, reports The Korea Herald.
The largest number of patents applied in Korea was hinge and housing technologies (86), followed by technologies to restore panels after unfolding (50), sensing users’ touch when folded (48) and cover window (22), according to the Korean Intellectual Property Office.
