This is a tiny monochrome 84 x 48 pixel LCD screen based on the PCD544 controller. This screen was originally designed for the Nokia 5110 mobile phone popular in the early 2000’s hence why this screen is also referred to as the Nokia 5110 LCD. It has been repurposed as a microcontroller LCD module due to its low price and simple serial interface. It is therefore ideal for basic microcontroller or Arduino projects requiring a small footprint and low cost.
The screen is transflective meaning it is visible in daylight without needing a backlight, however it also incorporates 4 LEDs positioned at each corner of the screen for low light conditions. These LEDs do lack the even light distribution of a standard backlight but do have the advantage of making the backlight very low power requiring only 4mA . This means it can be directly powered from an IO pin of most microcontrollers (please check your microcontroller specification before connection to an IO pin).
Interfacing to the display requires a simple 2 wire serial clock and data pin with 2 additional control pins for data/command and chip enable.
For Arduino users this display is supported by our HCDisplay library. See example below.
PLEASE NOTE: If you are using this display with a 5V microcontroller we recommend using level shifters.
