Retired RETIRED

This product has been retired from our catalog and is no longer for sale.

This page is made available for those looking for datasheets and the simply curious. Please refer to the description to see if a replacement part is available.

Replacement: None. We are no longer carrying this ding and dent LCD in our catalog. This page is for reference only.

Description: This is a basic 20 character by 4 line display. Utilizes the extremely common HD44780 parallel interface chipset (datasheet). Interface code is freely available. You will need ~11 general I/O pins to interface to this LCD screen. Includes LED backlight.

Note: These LCD screens have a variety of scuffs and slightly damaged screens due to a shipping issue. Therefore we are selling these at a lower price. Be aware that this is a Ding and Dent item and is not on par with our normal LCD quality.

Dimensions: 3.86 x 2.36 x 0.55"

  • I have discovered that some of the newer 20x4 LCD displays work at 3.3 volts. Dimmer than at 5 v, but still quite usable. Just think, direct connection to a Pi, Beaglebone Black, or PCDuino without level shifters. Has anyone tried these particular displays at 3.3 volts?

  • s/11/7/ since the LCD controller can be put into “4 bit” mode where only the upper nibble is needed to send/receive data. Indeed, in a pinch it’s even possible to get by with just five (D4-D7 and RS) if R/W is tied low and one depends on hard-coded timeouts that are “long enough” so that one can dispense with checking the state of E.

  • Is the blemish ALWAYS on the frame, or is there a chance that the actual screen is damaged? I don’t really care about a scuff as shown in the picture, so long as the screen material itself isn’t scratched..

    • we tried to remove any with bad scratches on the screen. you MIGHT see a small scuff or surface scratch on the screen, but none are deep. if you have any concerns, you might want to pass on them.

  • Is the equivalent product this one? https://www.sparkfun.com/products/9568
