The EVE chip really makes this TFT module really shine. EVE (embedded video engine) is a cool new technology from FTDI/Bridgetek that simplifies the process of displaying videos and text in an embedded project. All display, touch sensing, backlight, and audio features are controlled by the FTDI FT810 EVE which appears to host the MCU as a memory-mapped SPI device. The host MCU sends commands and data over the SPI protocol. The module can support both SPI and Quad-SPI.

If using a High Brightness Display, you can choose the AD Board which have light sensor function that can adjust panel"s brightness automatically.PCAP touch supports 10-finger multi-touch capability, light gloves and stylus touch (need to adjust the firmware),

Smart TFT LCD display embeds LCD driver, controller and MCU, sets engineer free from tedious UI & touch screen programming. Using Smart TFT LCD module, our customers greatly reduce product"s time-to-market and BOM cost.

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.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

The third example is a game. Actually it’s a replica of the popular Flappy Bird game for smartphones. We can play the game using the push button or even using the touch screen itself.

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.

Next we need to define the fonts that are coming with the libraries and also define some variables needed for the program. In the setup section we need to initiate the screen and the touch, define the pin modes for the connected sensor, the led and the button, and initially call the drawHomeSreen() custom function, which will draw the home screen of the program.

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.

Now we need to make the buttons functional so that when we press them they would send us to the appropriate example. In the setup section we set the character ‘0’ to the currentPage variable, which will indicate that we are at the home screen. So if that’s true, and if we press on the screen this if statement would become true and using these lines here we will get the X and Y coordinates where the screen has been pressed. If that’s the area that covers the first button we will call the drawDistanceSensor() custom function which will activate the distance sensor example. Also we will set the character ‘1’ to the variable currentPage which will indicate that we are at the first example. The drawFrame() custom function is used for highlighting the button when it’s pressed. The same procedure goes for the two other buttons.

So the drawDistanceSensor() custom function needs to be called only once when the button is pressed in order to draw all the graphics of this example in similar way as we described for the home screen. However, the getDistance() custom function needs to be called repeatedly in order to print the latest results of the distance measured by the sensor.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

PIT technology is a patented multi-touch technology. Based on the traditional infrared touch technology and the theory of total internal reflection (TIR), placing the infrared emission diode and reception diode on the lower surface of glass, the infrared beams generated by emission diodes are reflected through a prism light-guide specially designed and transmit across the front glass surface. Compared to traditional infrared touch technology, PIT touch screen has slimmer bezel, lower elevated height, and better multi-touch experience. Impact Display Solutions PIT touch screens have Win8 certification. PIT touch screens support multi-touch capability, allowing more people to touch the screen simultaneously. That allows users to have a better interactive experience. Compared to traditional infrared touch screen, 0.5mm ultralow elevated height enables PIT touch screen recognize human touch very accurately. Ultra-narrow bezel allows near-true flat appearance (as the touch transducers are placed under the screen). Protection performance enhancements are optional: waterproof or vandal-resistant.

As we all know, the biggest advantage of projected capacitive touch screens over other touch screen technologies is in the ease of implementation of feather-touch & multi-touch for gestures, but feather-style touching can lead to unintended activations in conventional projected capacitive touch screens. Adding force sensing overcomes that weakness of PCAPs. Force Sensing Touch Screens implement unintended touch rejection by ‘brushing off’ past accidents and it takes into account finger repositioning before selection. Force-sensing touch screen also enables new hand moves and menu-bringing features you can add to your product to enhance user experience.

Based on proven SAW touch technology, Impact Display Solutions has the capability of offering curved SAW touch screens in sizes of 21.5”, 27”, 32”, 35”, 42”. Furthermore, curved SAW touchscreens inherit and enjoy the benefits of SAW technology such as high reliability, protracted durability, sharp image clarity and vandal proofing. It’s the ideal touch solution for gaming and interactive kiosks.

Optical bonding can increase the brightness and contrast of a display. Typically, there are air gaps between the layers of the completed LCD assembly including the substrate, cover glass and touch screen. Optical bonding can be employed to strengthen the assembly and in most cases, to improve the overall brightness, contrast ratio and readability by mitigating the light reflection between the layers. We offer variety of bonding solutions to meet your LCD touch screen monitor requirements. Don’t miss out on the new products based on latest technological advances in this field. Examples of options include:

When you need to increase readability (especially in direct sunlight) by eliminating air gap between LCD and touch screen or protective lens, or both, Impact effectively achieves that goal with optical clear adhesive (OCA) lamination process. Dry bonding with OCA is an inexpensive bonding method with a reliable track record.

Performed in the U.S., Impact uses IR-curing process for optical bonding that involves infrared heat to bring optical silicone OCR material to gel state. Used to optically-bond touch screens of your choice or variety of lenses similar to options for UV curing listed above but excluding Micromesh option.
