This LCD module was used in old Nokia 5110/3310 cell phones. Now its been widely used by hobbyists for graphics, text etc.
Though it?s an industrial module, this LCD display is extremely easy to use. The Nokia 5110 is a basic graphic LCD screen for lots of applications. It was originally intended for as a cell phone screen.
Philips PCD8544 LCD driver, which is designed for mobile phones.
Low-cost monochrome LCD module comprised of 84 X 48 pixels that can be used to display rich graphics and text content.
It uses the PCD8544 controller, which is the same used in the Nokia 3310 LCD and interfaces to microcontrollers through a serial bus interface.
Low power CMOS LCD controller/driver, designed to drive a graphic display of 48 rows and 84 columns.
Pin Configuration :
CE? chip selection
DC? data/commands choice
DIN? serial data line
CLK? serial Clock Speed.
LIGHT? backlight control terminal
GND? power negative
Operation of Nokia 5110 LCD Display Module at 3.3V
Many devices that can be used with an Arduino, require a power supply of 3.3V. This is also the case with the Nokia 5110. The best way to deal with 3.3V devices is to take an Arduino Pro, which can run on 3.3V.
Internal clamp of the PCD8544 we can use a very simple level shifter. Four current limiting resistors of 10k? can do the job. When an LCD control line is high, the current through the 10k? resistor is just 40uA, so this is harmless.
Operation of Nokia 5110 LCD Display Module at 5V
VDD max = 7V, the PCD8544 controller can handle 5V, but the Nokia 5110 LCD works best at 3.3V. The four resistors of 10k? avoid streaks on the LCD display.
