TFT LCD modules are thin film field effect transistors. The so-called thin film transistor means that each liquid crystal pixel on the liquid crystal display is driven by a thin film transistor integrated behind it so that it can display screen information with high speed, high brightness, and high contrast. The composition of the liquid crystal display is not complicated. The liquid crystal panel plus the corresponding driving board (also called the main board, whose compositional structure is not intended to be the row and column driving circuit in the liquid crystal panel), power supply board, high voltage board, button control board, etc., constitute a complete liquid crystal display.

Power supply part: The power supply circuit of the liquid crystal display is divided into two parts: switching power supply and DC/DC converter. Among them, the switching power supply is an AC/DC converter, its function is to convert the AC 220V or 110V (European standard) into a 12V DC power supply (some models are 14V, 18V, 24V, or 28V), supply DC/DC Converter and high-voltage board circuit; DC/DC DC converter is used to convert the DC voltage (such as 12V) generated by the switching power supply into 5V, 3.3V, 2.5V and other voltages, which are supplied to the driver board and the liquid crystal panel.

The driver board of the TFT LCD screen is also called the main board, which is the core circuit of the liquid crystal display. It is mainly composed of the following parts: input interface circuit, A/D conversion circuit, clock generator, Sealer circuit, microcontroller circuit, and output interface circuit.

High-voltage board part: The high-voltage board is commonly known as a high-voltage strip (because the circuit board is generally long and in the form of a strip), and is sometimes called an inverter circuit or an inverter. Its function is to convert the low-voltage DC voltage output by the power supply into a liquid crystal panel ( The high-frequency high-voltage AC above 600V required by the Panel) that lights the backlight on the LCD panel. The high-voltage board of the TFT LCD screen mainly has two installation forms: 1. A dedicated circuit board; 2. It is installed together with the switching power supply circuit (the switching power supply adopts the internal type).

LCD panel part: The LCD panel is the core component of LCD, mainly including the LCD screen, LVDS receiver (optional, LVDS LCD screen has this circuit), driver IC circuit (including source driver IC and gate driver IC), timing sequence Control IC (TC0N) and backlight.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.
