What is Nokia 5510 LCD Display? Nokia 5510 LCD display is a graphic screen LCD display and have been used for lot of applications. Initially, it was designed only for iconic Nokia 5510 cell phone screen but now we can easily use it for different purposes such as for displaying alpha numeric character, draw lines, shapes and even for displaying bitmap images because of its 84*48 monochrome pixels mean 84 columns and 48 rows. All necessary functions of this display are packed in a single small chip which is operated at very low voltages. It is very low cost more precise, more reliable and easy to use LCD display. It is easily available in market or online shop. A simple Nokia 5510 LCD display is shown in figure 1

Pin Configuration of Nokia 5510 LCD Display
Every Nokia 5510 LCD display consists of eight pins which are used for different purposes. Its first one pin is reset pin and used for resetting the LCD display. during reset zero voltages are applied at this pin. Second one is CE pin, which is enable pin and is used for displaying any particular display when more then one SPI peripherals are in used. Third one is DC pin, which data/command pin and is used for switching data mode (high) to command mode (low). Forth one is DIN pin, which serial input pin and is used for serial communication means for sending serial instruction or data. Fifth one is CLK pin, which is clock pin and is used for suppling clock source because all SPI modules are required a common clock. Sixth one VCC pin, which is voltage supplying pin and is used for turning on or off the LCD display. For power on this LCD display 2.7 volts to 3.3 volts dc voltages are applied at VCC pin. Seventh one is BL pin, which is back light pin and used for power on the back light of this LCD display. Similarly, the last one is GND pin, which is ground pin and is used for supplying ground voltages to this LCD display. The pin configuration figure of this Nokia 5510 LCD display is shown in figure 2

Working Principle of Nokia 5510 LCD Display
The word LCD stands for liquid crystal display. Its name describes that every LCD display consists of liquid crystal. When electric current is passed through these crystals then magnetic field is produced. This magnetic field aligned the molecules of liquid crystal forcefully, then when they are aligned precisely then they allow the light to pass through these crystals. The working phenomena of every LCD display is almost same. But the voltages which are required to produce the magnetic field is different. On the biases of these voltages, the LCD display shows data which is coming from any type of controller. Two types of data are come from controller fist one is word data and second one graphic data. Each data produces different magnetic field and LCD display shows this data according to its magnetic field.
How to Interface Nokia 5510 LCD Display with Arduino Board
As we discussed in above paragraph a controller is required for displaying any type of data from Nokia 5510 LCD display. Any type of controller could be used with this LCD display but here we will tell how interface the Arduino board with this LCD display. Its interfacing diagram is shown in figure 3
Figure 3 Interfacing of Nokia 5510 LCD Display with Arduino Board
According to the figure 3 Nokia 5510 LCD display is directly connected with Arduino board. Because LCD display operates at 2.7 volts to 3 volts therefor it is directly powered up with Arduino board. All the pins of LCD display are connected with Arduino board according to figure 3 but the resistors are connected in series with these pins. If we are using Arduino Uno then 10K Ohm resistor is connected between RST, D/C, DN and SCLK pin.1K ohm resistor is connected between SCE and pin 7. Similarly,330 ohm resistor is connected between pin 9 and LED pin. Then program is upload in Arduino board with the help of Arduino IDE software.
