TFT Touch Shield V2.0 is a resistive touch screen, compatible with Arduino/Seeeduino/Arduino Mega/SAMD21 platforms. It can be used as display device or sketch pad. Compared with the previous version, 2.8""TFT Touch Shield V1.0, we upgraded the screen driver to a more professional chip, ILI9341 driver, providing different pin-saving SPI communication without sacrificing the data transmitting speed. Due to the communication method change, programs developed for the original version are needed for modification before being transplanted to the new version. With a SD card module integrated on this shield, this shield reserves capability for other expansions of your project.

At present, TFT LCD touch panel prices rebounded, after six months of continuous decline, TFT LCD touch panel prices began to rebound at the end of July. Global TFT LCD panel prices have rebounded since August, according to Displaysearch, an international market-research firm. The price of a 17-inch LCD touch panel rose 6.6% to $112 in August, up from $105 in July, and fell from $140 in March to $105 in July. At the same time, 15 – inch, 19 – inch LCD touch panel prices also showed a different range of recovery. The price of a 17-inch LCD touch panel rose 5.8 percent, to $110, from $104 in late July, according to early August quotes from consulting firm with a view. Analysts believe the rebound will continue through the third quarter; LCDS will see seasonal growth in the third quarter, driven by back-to-school sales in us and the completion of inventory liquidation in the first half of the year. Dell and Hewlett-Packard (HPQ) started placing orders for monitors in the third quarter, and display makers Samsungelectronics (SXG) and TPV (TPV) are expected to increase production by 25% and 18% respectively.

It seems that due to the increasing demand in the market, the production capacity of the display panel production line has been released. Domestic TFT-LCD touch panel makers boe and Shanghai guardian said their production schedules have been set for September, and their production capacity may reach full capacity by the end of the year. Jd will produce 85,000 glass substrates per month (with a designed capacity of 90,000), according to boe and Shanghai guardian. Previously, panel makers have been hit by falling prices, with boe, SFT, and even international panel giant LG Philips all reporting losses. If the rebound continues into the fourth quarter, boe, Shanghai radio and television and other panel makers will use the rebound to reverse the decline, according to industry analysts.

It is understood that the first quarter of the boe financial results show that the company’s main business income of 2.44 billion yuan, a loss of 490 million yuan.Jd.com attributed the loss to a drop in the price of 17-inch TFT-LCD displays made by its Beijing TFT-LCD fifth-generation production line of Beijing boe photoelectric technology co., LTD., a subsidiary. Boe has issued the announcement of pre-loss in the first half of the year in April. Due to the influence of the off-season of TFT-LCD business operation in the first quarter of 2006, the company has suffered a large operating loss, and the low price in the TFT-LCD market has continued till now. Therefore, it is expected that the operating loss will still occur in the first half of 2006.LG Philips, the world’s largest TFT LCD maker, reported a won322bn ($340m) loss in July, compared with a won41.1bn profit a year earlier.LG Philips attributed the loss to fierce price competition and market demand did not meet expectations.

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.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

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.
