9.7inch e-Paper 9. Handling, Safety and Environmental Requirements and Remark Warning The display glass may break when it is dropped or bumped on a hard surface. Handle with care. Should the display break, do not touch the electrophoretic material. In case of contact with electrophoretic material, wash with water and soap. Caution The display module should not be exposed to harmful gases, such as acid and alkali gases, which corrode electronic components.
