Thanks to the high contrast and wide viewing angle of the RCM1277U-A, which is provided by its unique design
technology, this module brings forth new applications in brand new LCD fields. ROHM large-sized LCD units are perfect
displays for information or sign boards. As a media for informational display, large-sized LCD units must possess high
visibility, wide viewing angles, and other such superior qualities. ROHM large-sized LCDs boast an excellent track record
and possess guaranteed functionality for assured satisfaction in a variety of situations.

!Operation notes
(1) Attention points in handling
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 liquid crystal
contacts your clothing or body, wash immediately with
soap and water.
Do not touch the IC lead electrodes or the electrode ter-
minal components.
If the module is to be used for long periods subjected
to direct sunlight, employ a filter to block the ultraviolet
rays.
Do not store the module in areas of high temperature
or high humidity. Do not store the module in locations
exposed to direct sunlight or fluorescent light.
During handling of the module, in order to prevent
damage to the tab, do not bend it more than two times.
(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 it off, turn off the input signal
first. Otherwise the IC may be damaged by the latch-
up phenomenon.
(3) Precautions during installation
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.
A protective film is pasted over the front and back of
the module to protect the panel surfaces. When peel-
ing this film off, be sure to peel as slow as possible in
order to minimize the generation of static electricity.
Use of a ion blower or other deionizing device is rec-
ommended.
