Nokia 51110 LCD Display module developed for use with the iconic Nokia 5110/3316 mobile phone. It is capable of displaying alphanumeric characters, drawing lines, other shapes, and even displays a bitmap image. All this is possible only because of 84*48 monochrome. Nokia 51110 LCD Display module consists of an inbuilt PCD8544 interface IC which is easy to use with low-level microcontrollers. The PCD8544 is a low power CMOS LCD controller. Designed to drive a graphic display of 48 rows and 84 columns. This module communicates through the DSPI protocol, hence there is no need for more pins to communicate. This module has an inbuilt added library for Arduino which makes it ideal for novice programmers.
Nokia 5110 LCD module works on 3.3v and hence all pins are only 3.3 v tolerant. So in case if we are using a 5v microcontroller we need to use a logic level shifter. This level shifter acts like a potential divider to access the SPI pins of the display module. An on-chip generation of the LCD display and a bias voltage are inbuilt in the single-chip LCD display, as a result, minimum, external components and low power consumption is required.
The LCD in the Nokia 5110 comes with a backlight of different colours like green and blue. The bit pattern displays on 50 bytes of Graphic Display Data Ram (GDDR) on the PCD8544 LCD driver. Organized in 6 banks (0 to 5) with each bank containing 84 columns (0 to 83) that store 8 bits of data. Here each bit represents particular pixels on the screen which can programmatically turn ON or OFF.
