MOSAIC DISPLAY UNIT
RCM1637U-A
Thanks to the high contrast and wide viewing angle of the RCM1637U-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.
