zOperation note
(1) Handling precautions
• Protect the module from strong shocks as they can cause damage or defective operation.
• The polarizing plate on the surface of the module is soft and can easily be scratched. Wipe away dirt and dust
using an alcohol-based cleanser.
• If the liquid crystal panel is damaged and the liquid crystal contacts your clothing or body, wash immediately with
soap and water.
• If the module is to be used for long periods subjected to direct sunlight, employ a filter to block the ultravioletrays.
•Do not use the module in areas of high temperature or high humidity. Do not use the module locations exposed to
direct sunlight or fluorescent light.
•A protective film (polyethylene) is pasted over ROHM liquid crystal modules to protect the panel surfaces. When
peeling this film off, be sure to peel as slow as possible in order to minimize the generation of static electricity.
(2) Precautions during operation
• Do not connect or disconnect the module while the power supply is turned on.
• Input the input signal after the module power supply is turned on. When turning if off, turn off the input signal first.
Otherwise the IC may be damaged by the latch-up phenomenon.
(3) Precautions during installation
• Be sure to use a grounded soldering iron when performing any installation procedures.
• Be careful to avoid damage from static electricity. A CMOS-IC is used in the modules circuitry that can be easily
damaged by static electricity.
(4) Precautions during unit assembly
• In order to protect the polarizing plate from dirt or scratches, it is recommended to use a protective cover on the front
surface.
(5) Precautions for COG module
• Do not subject the front and back surface of the IC to light. Doing so may cause defective operation.
• When peeling off the protective film of the panel, use of an ion blower or other device to reduce the generation of
static electricity is recommended.
• No special measures are taken to prevent the generation of static electricity on the module. Therefore, be sure to
take the appropriate measures to prevent the generation of electrical charge on the LCD module by the design of the
product itself.
