Crystalfontz 632 USB LCD Screen review

Today we'll be taking a look on the Crystalfontz CFA632FNLY-U LCD screen from LC Design. This LCD screen is the 632 LCD screen from Crystal Fontz with a USB connection. It has 2 lines with a Yellow/Green LED Backlight and it's STN Negative, Blue. The USB connection makes the installation easier because you only need one cable for both power and data. The serial LCD modules need 2 cables, one for data and one for power. The USB version is fully compatible by using a 'Virtual COM port" driver.

CrystalFontz 632 USB LCD screen Feature list

The LCD material for the positive displays is FSTN (Film compensated Super Twisted Nematic) instead of STN. FSTN gives better contrast, faster response and makes an all-around more readable display.

The display has the ability to store a customized boot screen of your design in its EEPROM. All features of the display are controlled: characters displayed, user-definable characters, backlight setting, contrast setting, cursor position, cursor style, “wrap” setting, “scroll” setting, and even the scrolling marquee.

The CGROM is an enhanced version with many more useful characters: numeric superscripts, icons, mathematical symbols, some fractions, a great variety of arrows, many currency symbols, and more.

Available with 632 PC Mounting Bracket

Large, easy to read characters: 7.3mm (0.287") character height

Available with bright, even, software adjustable LED backlighting or in a low-power reflective model

Software controlled contrast

"Gapless" horizontal bargraphs

Software controlled terminal style automatic scrolling and line wrapping

Unique "Scrolling Marquee" feature continuously scrolls a message across the display without host intervention.

Buffered communication

Single board construction--no connectors to fail

Large display area in a compact 108mm x 43mm (4.25" x 1.69") package

Thin:

Reflective is 15.9mm (0.626") including DB-9 connector
LED Backlit is 19.9mm (0.783") including DB-9 connector

The USB converter board and its compact connector does not add to the overall thickness of the module.

Negative voltage for contrast generated on board

The LCD screen came well packed in a box within a sheet of bubble plastic. In the package I also found the additional drive bay mounting bracket

From left to right : on the first pic you can see the LCD screen. Without being powered up it looks dark blue. The second pic is the PCB plate on back of the screen. On the right you can see 2 little switches, they are used to config the baud rating of the LCD screen. Even more to the right you have a serial connector, and in the lower middle you have an extra PCB plate which is used for the USB connection. On picture number three you can see the USB connector.

From left to right : On the first picture you have the black mounting bracket. It consists out of an iron bracket with a black adhesive plastic front attached to it. Also note that it has a clear plastic to protect the screen of your LCD module. On the second pic you can see the back of it and the screws to mount the LCD screen. On the third pic the LCD screen mounted in the mounting bracket. And on the last picture you can see the back of the bracket with the LCD screen installed. Installing it is really simple.
