Features

CU-U Series Product Concept

The CU-U series displays are all built with LCD compatible dimensions and HD44780 command sets. These displays are easy to read due to high contrast, have wide viewing angles and are easier to read at short and long distances. Additionally, VFD displays have a quick display response within the module’s temperature range of -40C to +85C. Noritake offers long term supply and engineering support with their products.

CU-U Series Product Concept

LCD Replacement Modules

The majority of the CU-U series modules have the same footprint as their LCD counterpart. This means that the PCB and pount holes are the same size for the following character grid sizes:
16×2, 20×2, 24×2, 20×4, 40×2 and 40×4

LCD Replacement Modules

Extra Features

The CU-U series includes modules with a brightness control feature and all modules have a high speed response time.

Interface Options

  • Serial Interface
  • 4/8 bit Parallel Interface
Interface Options

Brightness Boost Model

Great in high ambient light conditions with a brightness boost of up to 200%.
Applicable models:

  • CU16025-UX6J
  • CU16025-UX6A
  • CU20025-UX1J

Compact Model

Space saving models for an enclosure/front panel. These displays have a slim PCB height of less than 1” and brightness boost.
Applicable models:

  • CU16024-UX3J
  • CU20024-UX3J
Compact Model

Built-in Controller VFD (BC-VFD): A Flexible Solution

Built-in HD44780 controller without the need of a PCB saves money and space. The BC-VFD has 16 levels of brightness along with a selectable font table and synchronous serial interface.

Built-in Controller VFD (BC-VFD): A Flexible Solution

CU-U Code Library

There is currently a code library that provides access to the basic functionality of the CU-U series modules using 8-bit Atmel AVR. This library is intended for use with the following modules:

  • CU******-UW**
  • CU******-UX**
  • DS2045G

≫ Noritake_VFD_CUU
≫ Noritake_VFD_CUU_Graph
≫ Noritake_VFD_CUU_BrightnessDemo
≫ Noritake_VFD_CUU_BarGraphDemo

CU-U Code Library

  1. Covers all display commands.
  2. Written in standard C++ for AVR Studio 4 and Atmel Studio 6.
  3. Example programs can be downloaded separately.

Why is VFD Easier to Read Than Other Displays? >

Wavelength (nm)
It’s because the vibrant green light illuminating from the VFD shares similar spectrum as one of the three color-sensing cone cells.

Display Response Time Comparison

Difference >

How different is the display response?
VFD vs LCD Display Response Time
Learn More >
Response time is more noticeable in below 0° conditions. VFD performs better while LCD freezes.

How VFD Works >

Vacuum Fluorescent Display (VFD)
How VFD Works
The VFD responds at the speed of light. VFD illuminates by the electron moving at the speed of light through the grid to the anode in a vacuum environment.
Since VFD is vacuum inside, VFD is not effective by below 0° condition. Instead VFD performs better at below 0° condition.
Learn More >

How LCD Works >

Liquid Crystal Display (LCD)
How LCD Works
The display response time for LCD is determined by the time it takes for the liquid crystal molecules to untwist and straighten out.
Unlike the VFD, LCD freezes at below 0° condition causing the LCD to perform very slow.
