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.

Unfortunately, this is where it loses significant points. If I were rating it on viewing angle alone it would get one star even. I"ve never seen a screen this bad in that respect and I have used laptops in the MS-DOS days when LCD latencies were practically measured in seconds rather than milliseconds (pro-tip, NEVER play Descent on a laptop with really really high LCD latency. You WILL be sick.) Left and right viewing angle are great -- which is ironic because in most applications for this thing left and right aren"t that big of an issue -- but the up and down viewing angle literally couldn"t be any worse. Specifically, you can NOT look at this thing directly straight on. It MUST tilt up away from you so you"re basically looking up at it somewhat. I would estimate it has to go about 25-30 degrees or so off from being parallel. That"s pretty extreme to the point of being a bit ridiculous. The stand doesn"t do high precision either on the tilt, so you won"t really get it at quite an optimal angle and just have to get it as close as you can (about 35 or so I guess is what it works out to if you get it on the closest catch and then tilt it just a bit.) If you get at all close to looking at it parallel it turns insanely dark and you can"t see details or color well at all -- even text is insanely hard to read. As you approach 90 degrees, it starts to invert before you even actually get to a straight head-on look at it. Any higher and it outright inverts. If you can tilt it just right, the colors are pretty close to an IPS panel almost even (a bit lacking compared to a real IPS, but better than most TFT panels.) But this unreasonable viewing angle is extremely offputting. Also, as a side effect, since it has to stay tilted upwards, this means it collects dust like there is no tomorrow. That"s even more offputting. If it didn"t have such good visual clarity and color production I"d have to give it only one star even. Unfortunately, no matter how you position it, it will never be QUITE right with colors a bit more washed than they should be at one angle and too dark to even see at another. If you"re buying this just to act as a camera monitor or a simple screen for a server or something it will work great, but if you buy it for handling something like an OpenElec system, you"ll probably be very unhappy with the ridiculous viewing angle.

LCD display doesn’t operate the same way as CRT displays , which fires electrons at a glass screen, a LCD display has individual pixels arranged in a rectangular grid. Each pixel has RGB(Red, Green, Blue) sub-pixel that can be turned on or off. When all of a pixel’s sub-pixels are turned off, it appears black. When all the sub-pixels are turned on 100%, it appears white. By adjusting the individual levels of red, green, and blue light, millions of color combinations are possible

The pixels of the LCD screen were made by circuitry and electrodes of the backplane. Each sub-pixel contains a TFT (Thin Film Transistor) element.  These structures are formed by depositing various materials (metals and silicon) on to the glass substrate that will become one part of the complete display “stack,” and then making them through photolithography. For more information about TFT LCDs, please refer to “

The etched pixels by photolith process are the Native Resolution. Actually, all the flat panel displays, LCD, OLED, Plasma etc.) have native resolution which are different from CRT monitors

HD TV has 1280×720 = 921,600 pixels; Full HD has 1920x 1080=2,073,600 pixels; 8K TV has 7,680×4,320=33,177,600 pixels. he “K” in 8K stands for Kilo (1000), meaning a TV that has achieved a horizonal resolution of about 8,000 pixels.

Although we can define a LCD display with resolution, a Full HD resolution on screen size of a 15” monitor or a 27” monitor will show different. The screen “fineness” is very important for some application, like medical, or even our cell phone. If the display “fineness” is not enough, the display will look “pixelized” which is unable to show details.

A lot of times, we heard about what is the DPI of your monitor, actually it is not a exact correct saying. Please find the definition of DPI and PPI as below.

But you see other lower resolution available, that is because video cards are doing the trick. A video card can display a lower LCD screen resolution than the LCD’s built-in native resolution. The video cards can combine the pixels and turn a higher resolution into lower resolution, or just use part of the full screen. But video cards can’t do the magic to exceed the native resolution.

Abbreviation: QVGA, VGA, HD, FHD, 1080p, 1440p, 4K etc. It is very straight forward for different applications. For TV buyers, they can simply focus on 4K, 8K etc; for industrial engineers, they most likely focus on VGA, HD, WVGA etc.

Aspect Ratio:  You might hear 4:3 which is full screen, 16:9 is for widescreen; 21:9 is for ultrawide computer monitors and televisions, as well as cinematic widescreen projectors. Some ultrawide monitors are trying to replace dual monitor.
