Nokia 5110 LCD is disassembled from the old phone, so it’s always second-hand, and some tiny problems will come with it. NOT THE SAME PINOUT AS RED

Potential Quality Problems :

• The LCD main not fully locked on the board, please press it a little bit and it will work well.
• Few LCD pixels may be broken, only very few broken pixcels, around 1~2 % broken pixels in every one out of ten pieces, you can see it directly when if power off when you receive it, this will be only very few pixels, but if you are restrict to display quality, please be aware to choose this.
• It is recommended to buy the EDS LCDs, 2.2” and 1.8” available.

These displays were used in old Nokia 5110/3310 cell phones (before the smart-phone fad turned every cell phone into a TV). It’s a 84×48 pixel monochrome LCD display. These displays are small, only about 1.5″ diagonal, but very readable and come with a white backlight. This display is made of 84×48 individual pixels, so you can use it for graphics, text or bitmaps. These displays are inexpensive, easy to use, require only a few digital I/O pins and are fairly low power as well

To drive the display, you will need 3 to 5 digital output pins (depending on whether you want to manually control the chip select and reset lines). Another pin can be used to control (via on/off or PWM) the backlight – the backlight LEDs are wired to a transistor.

The display driver is a PCD8544 chip, and it runs at 3.3V so you’ll need a 3V supply handy (you don’t need that much current though, maybe 10mA tops). Logic levels must be 3V to prevent damage but we include a free level shifter chip so you can easily connect it to 5V logic such as an Arduino.

Of course, we wouldn’t just point you to a datasheet and say “good luck!” To make it easy for you to use the display, we’ve written a nice graphics library that can print text, pixels, rectangles, circles and lines. The library is written for the Arduino but can easily be ported to your favorite microcontroller.
