An Arduino display can serve a variety of purposes. Since micro controllers usually read data from sensors, a display allows you to see this information in real-time without needing to use the serial monitor within the Arduino IDE.

But there are different types of displays that you can use, and they each have theirs pros and cons.

1. Liquid Crystal Display

LCD screens(Liquid Crystals Display) are widespread electronics displays in various devices.

Although these LCDs are available in various sizes (16×1, 16×2, 20×4, etc.), they all share the same Hitachi LCD controller HD44780 so you can swap them easily.

Liquid Crystal Display

It can display 16 characters on each line in a 5×7 pixel matrix. This LCD is capable of displaying 224 different characters.

Command and Data Registers are present on this LCD. The command register and Data register store various values are given to the display.

To control the display, you must put the data from the image in the data register and instructions in the instruction registers. 

In your Arduino project, Liquid Crystal Library simplifies this, so you don’t need to know the low-level instructions.

You can vary the brightness using the potentiometer to be connected across the VEE pin.

Can an Arduino run an LCD display?

These LCDs can be controlled using two modes: 

  • 4-bit mode
  • 8-bit mode 

The 4-bit mode requires seven I/O pins from the Arduino, while the 8-bit mode requires 11 pins. For displaying on the screen, you can do most everything in a 4-bit way. It benefits you.

Wiring 16×2 LCD with Arduino UNO

This circuit diagram is self-explanatory. Most of Arduino’s projects use 4-bit mode. Because of that, it saves the Arduino Pins. 

The standard LCD pinout is given in the table below:

Pin no.Pin NameArduino ConnectionPin Description
1VSSGNDSignal ground
2VCC5 VLogic power for LCD
3VEE/VO10 kΩ PotentiometerContrast adjustment
4RSPin 2Register select
6EPin 3Enable Operation
7 to 14D0 – D7Data bus lines used for 8-bit mode
11 to 14D4 – D7Pin 4 – 7Data bus lines used for 4-bit mode
15LED+5 VAnode for LCD backlight
16LED-GNDCathode for LCD backlight

2. Graphical Liquid Crystal Display

The Graphical LCD (GLCD) is entirely different from ordinary LCD. Ordinary LCDs can only display simple text or numbers within a fixed size.

The GLCD has 128 * 64, equal to 8192 dots or 8192/8 = 1024 pixels, so apart from characters, you can display any graphical image, string, or character on this GLCD.

There are three different ways you can interface the GLCD with Arduino.

  •  4-bit Parallel Mode
  •  8-bit Parallel Mode
  •  Serial Mode

Many types of GLCD controllers are available in the market, like KS0108, SSD1306, ST7920, SH1106, and SSD1322.

3. Seven-Segment Displays

A seven-segment display is a simple type of display. This display is the most common device for displaying digits (most of 0 – 9) and the alphabet.

Some displays can also show characters and images.

LEDs (Light-emitting diodes) or LCDs in seven-segment displays made it.

These displays contain 7-segments, and an extra 8th segment is used to display dots.

These seven-segment display circuit diagrams are shown below:

Seven-Segment Displays

There are two types of seven-segment displays available in the market. According to the type of application, these displays can be used.

  • Common Anode Display
  • Common Cathode Display

The most common electronic devices like microwave ovens, calculators, washing machines, radios, digital clocks, etc., display numeric information.

5. TFT LCD Display

TFT LCD is a variant type of LCD that uses Thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. 

A TFT LCD is an active-matrix LCD, in contrast to passive-matrix LCDs or simple, direct-driven LCDs with a few segments. Easy to Interfacing with a TFT LCD and Arduino. 

You can start the display using the I2C and SPI communication interface between the Arduino and the TFT LCD.

In the market, various sizes of TFT LCD are available.

  • 1.8” Display with a resolution of 160 x 128 Pixels.
  • 2.0” Display with a resolution of 220 x 176 Pixels.
  • 2.4” Display with a resolution of 320 x 240 Pixels.

7. Dot-matrix Display

Dot Matrix LED display is used for displaying information. Dot-matrix refers to a two-dimensional array of LEDs that can represent symbols, characters, and images.

Cell phones, televisions, and other modern display applications use Dot matrices. 

LED matrices are available in dimensions like 5 x 7, 8 x 8, 16 x 16, 32 x 32, and different styles like single color, dual color, multi-color, or RGB LED matrix. 

It is usually available as a single color LED matrix, but the dual color and RGB LED Matrix are also possible.

The 8×8 matrix consists of 64 dots or pixels. In dot matrices, a total of 16 pins are occupied.

You can see the diagram of it using the following figure.

8x8 Dot Matrix

How many displays can an Arduino run?

Arduino can run a maximum of two displays simultaneously, but it depends on the type of display and what else you have connected to your output pins. You can run more displays than this if you add additional hardware.

Comparison of Arduino Compatible Displays

In this section, I will tell you how to select the display for your electronics project with an Arduino Board.

If you are using MCU with more GPIOs, have enough physical space, and want to display different characters for any data, information, and graphics, then you can go for Liquid Crystal Display (LCD) or Graphical Liquid Crystal Display (GLCD).

They are primarily used in embedded systems.

If you only want to display some numbers and alphabets, then Seven-Segment Display or Dot-matrix Display is best suitable for such a project.

It is mainly used in digital clocks, calculators, counters, electronic meters, etc.

If you have a very compact project and you want to use fewer GPIOs and color graphics, then OLED is the best option. It is widely used in smartwatches, pulse oximeters, etc.

If the project needs high-quality graphics with GUI and also if you want touch operation, then TFT LCD or TFT LCD touchscreen is the most suitable.

It is widely used in mobile devices, cameras, aircraft devices, etc.


After this tutorial, you can easily choose the right displays corresponding to your project.

You have learned how to connect your displays with the Arduino Board, and you can follow the links I shared to more in-depth tutorials that we have on this site for each different display type. 

I hope you found this tutorial informative. If you did, please share it with a friend who likes electronics and making things!

I would love to know what project you plan on building or have already made with the Arduino.
