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.

Focus Displays offers a wide range of standard full color TFT displays. 64 million unique colors, high brightness, sharp contrast, -30C operating temperature, and fast response time are all good descriptions of a TFT display. This is why TFT technology is one of the most popular choices for a new product.

Thin Film Transistor (TFT) display technology can be seen in products such as laptop computers, cell phones, tablets, digital cameras, and many other products that require color. TFT’s are active matrix displays which offers exceptional viewing experiences especially when compared to other passive matrix technologies. The clarity on TFT displays is outstanding; and they possess a longer half-life than some types of OLEDs and range in sizes from less than an inch to over 15 inches.

CCFL’s are still available, but are becoming a legacy (obsolete) component. TFT displays equipped with a CCFL require higher MOQs (Minimum Order Quantities) than displays with LED backlights.

The majority of TFT displays contain a touch panel, or touch screen. The touch panel is a touch-sensitive transparent overlay mounted on the front of the display glass. Allowing for interaction between the user and the LCD display.

Some touch panels require an independent driver IC; which can be included in the TFT display module or placed on the customer’s Printed Circuit Board (PCB). Touch screens make use of coordinate systems to locate where the user touched the screen.

Resistive touch panels are the lowest cost option and are standard equipment on many TFT modules. They are more common on smaller TFT displays, but can still be incorporated on larger modules.

Contrast ratio, or static contrast ratio, is one way to measure the sharpness of the TFT LCD display. This ratio is the difference between the darkest black and the brightest white the display is able to produce. The higher the number on the left, the sharper the image. A typical contrast ratio for TFT may be 300:1. This number ratio means that the white is 300 times brighter than the black.

TFT LCD displays are measured in inches; this is the measurement of the diagonal distance across the glass. Common TFT sizes include: 1.77”, 2.4”, 2.8”, 3”, 4.3”, 5”, 5.7”, 5.8”, 7”, 10.2”, 12.1 and 15”.

TFT resolution is the number of dots or pixels the display contains. It is measured by the number of dots along the horizontal (X axis) and the dots along the vertical (Y axis).

Certain combinations of width and height are standardized and typically given a name and a letter representation that is descriptive of its dimensions. Popular names given to the TFT LCD displays resolution include:

Transmissive displays must have the backlight on at all times to read the display, but are not the best option in direct sunlight unless the backlight is 750 Nits or higher. A majority of TFT displays are Transmissive, but they will require more power to operate with a brighter backlight.

A primary job of the driver is to refresh each pixel. In passive TFT displays, the pixel is refreshed and then allowed to slowly fade (aka decay) until refreshed again. The higher the refresh frequency, the sharper the displays contrast.

The TFT display (minus touch screen/backlight) alone will contain one controller/driver combination. These are built into the display so the design engineer does not need to locate the correct hardware.

If you do not see a Thin Film Transistor (TFT) Display module that meets your specifications, or you need a replacement TFT, we can build a custom TFT displays to meet your requirements. Custom TFTs require a one-time tooling fee and may require higher MOQs.

Aspect ratio is the relationship of the width of a video image compared to its height. The two most common aspect ratios are4:3, also known as 1.33:1 or fullscreen, and 16:9, also known as 1.78:1 or widescreen. (Larger aspect ratio formats are used in the motion picture industry.)

All the older TV’s and computer monitors you grew up with had the squarish 4:3 shape– 33% wider than it was high. These are often referred to as square monitors.  4:3 LCD monitors can display analog video signals that conform to NTSC and PAL standards. They are not capable of displaying HD (high-definition) video.

The 4:3 aspect ratio dates back to 1917, when the Society of Motion Picture Engineers adopted it as the standard format for film. In the 1930’s, the television industry adopted the same 4:3 standard. But in the mid-1950’s, the motion picture industry began developing several widescreen formats to improve their decreasing audience numbers. Television broadcasting stayed with the 4:3 standard, until the recent move to HDTV and 16:9 widescreen.

16:9 is the native aspect ratio of most high-definition widescreen LCD monitors and TV’s (16:9 and 16:10 are very similar). It is 78% wider than it is tall, and fully one-third wider than a 4:3 screen. 16:9 widescreen monitors are ideally suited to display HD video signals. Some models can also display SD (standard definition) video signals, but this will require some compromises, as you will read below.

Nearly all experts agree that in order to display optimal video images, it is critical to match the aspect ratio of the monitor to the aspect ratio of the camera (or other incoming video source). Below is a example of a 16:9 image on a 16:9 widescreen lcd monitor:

However, many cameras in the industrial, commercial, security, and law enforcement industries still utilize 4:3 CCD or CMOS imagers. Therefore, to display clear, undistorted video images, it is important to utilize monitors with the same 4:3 aspect ratio to match the cameras. Failure to do so will result in distorted images, as shown below.

Unfortunately, despite the continued widespread use of 4:3 cameras, LCD monitors with a 4:3 aspect ratio are getting harder and harder to find. Many manufacturers have abandoned them in favor of the newer 16:9 widescreens. TRU-Vu Monitors still offers a complete line of industrial-grade 4:3 aspect ratio LCD monitors. These range in size from 5.5″ to 19″ screens. They are available with standard, waterproof, steel or open frame enclosures. They can be touch screen,  sunlight readable, medical-grade, or optically bonded.

16:9 widescreen LCD monitors are the ideal complement to 16:9 format HD cameras. These are increasingly used in video conferencing, broadcast and medical applications. They display superb, distortion-free, high-definition images. TRU-Vu Monitors offers these in 7″, 10.1″, 13.3″, 15.6″, 17.3″, 18.5″ and 21.5″ to 65” LCD screen sizes, in standard, touch screen, sunlight readable, medical-grade, optically bonded and open frame configurations.

You must avoid video images which are stretched, chopped, squeezed, shrunk or distorted. Be sure to choose a LCD monitor with the correct aspect ratio (4:3 aspect ratio or 16:9 aspect ratio) that matches your camera or other incoming video signal.
