Samsung Display may use transparent polyimide film on large foldable devices
However, in addition to folding mobile phones, Samsung also plans to launch folding notebooks or tablet computers, and the durability of ultra-thin glass on such large-sized devices is a problem. The larger the size, the easier it is to crack the ultra-thin glass, and devices such as folding screen notebooks have a much larger panel size than mobile phones. Therefore, Samsung Display is also considering the use of transparent polyimide films on the OLED panels of these large-scale folding devices.
As the main rival of Samsung Display, LG Display currently uses transparent polyimide film as the glass cover on the display panel of the folding device.
