8.3 Reflection Ratio
The reflection ratio is expressed as:
R = Reflectance Factorwhite board x ( Lcenter / Lwhite board )
Lcenter is the luminance measured at center in a white area (R=G=B=1). Lwhite board is the luminance of a standard
white board. Both are measured with equivalent illumination source. The viewing angle shall be no more than 2
degrees.

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.
Disassembling the display module can cause permanent damage and invalidate 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.
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)
(6) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like
chamois soaks with petroleum benzene. Normal-hexane is recommended for cleaning the adhesives used to
attach the PS. Do not use acetone, toluene and alcohol because they cause chemical damage to the PS.
(7) Wipe off saliva or water drops as soon as possible. Their long time contact with PS causes deformations and
color fading.
Data sheet status
Product specification
This data sheet contains final product specifications.
Limiting values
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or
more of the limiting values may cause permanent damage to the device. These are stress ratings only and
operation of the device at these or at any other conditions above those given in the Characteristics sections of
the specification is not implied. Exposure to limiting values for extended periods may affect device reliability.
Application information
Where application information is given, it is advisory and does not form part of the specification.
Remark
All the specifications listed in this document are guaranteed for module only. Post-assembled operation or
component(s) may impact module performance or cause unexpected effect or damage and therefore listed
specifications is not warranted after any post-assembly operation.
