10. HANDLING, SAFETY, AND ENVIRONMENT REQUIREMENTS
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. Disassembling the display module.
Disassembling the display module can cause permanent damage and invalidates the warranty
agreements.
IPA solvent can only be applied on active area and the back of a glass. For the rest part, it is not
allowed.
The module storage environment must under reliability test storage item’s criteria.
Mounting Precautions
(1) It`s recommended that you consider the mounting structure so that uneven force (ex. Twisted
stress) is not applied to the module.
(2) It`s recommended that you attach a transparent protective plate to the surface in order to
protect the EPD. Transparent protective plate should have sufficient strength in order to resist external
force.
(3) You should adopt radiation structure to satisfy the temperature specification.
(4) Acetic acid type and chlorine type materials for the cover case are not desirable because the
former generates corrosive gas of attacking the PS at high temperature and the latter causes circuit
break by electro-chemical reaction.
(5) Do not touch, push or rub the exposed PS with glass, tweezers or anything harder than HB
pencil lead. And please do not rub with dust clothes with chemical treatment. Do not touch the surface
of PS for bare hand or greasy cloth. (Some cosmetics deteriorate the PS)
