Introducing a highly responsive touchscreen monitor that brings a new dimension of interactive functionality to the workplace. This 20-inch-class touchscreen LCD panel delivers full HD resolution with performance-enhancing UV2A technology. Its 10-point multi-touch screen provides extremely quick response for writing and touch gestures. When connected to a device running Windows® 8, the monitor serves as a beautifully intuitive interface.

The LL-S201A is capable of recognising 10 touch points at once. This expands touch interface applications beyond onscreen writing to include gaming, typing via an onscreen keyboard, playing virtual musical instruments, and more.

The LL-S201A is compatible with devices running Windows® 8, the latest operating system from Microsoft. Windows® 8 supports smooth and intuitive touchscreen functionality, which can be experienced to its fullest on this beautifully responsive LCD monitor.

Incorporating a highly sensitive capacitive touchscreen, the LL-S201A offers precise recognition of onscreen input, whether it originates from a hand or pen. As well as being sensitive enough to detect the bundled pencil-slim touch pen, the LL-S201A can also distinguish pen and hand input, for stress-free onscreen writing.

The dedicated touch pen allows smooth and extremely accurate onscreen writing of fine text and lines—it’s just like writing on paper. The LL-S201A’s pen features an extra-small 2-mm tip that enables users to easily underline text, add notations, draw illustrations, and make amendments to onscreen content.

The LL-S201A supports Microsoft® Office ink functionality, allowing the user to write on Excel® or Word documents displayed onscreen and save the files—notations and all.

The bundled Sharp Pen Software lets users enjoy natural handwriting functionality. Once documents have been imported as images and displayed on the touchscreen, users can quickly write and draw directly on the screen surface using the bundled touch pen or a finger. Sharp Pen Software also features an overlay mode that enables onscreen handwriting regardless of the application being used.

A touch of the onscreen Rotate icon rotates the screen content 180 degrees, making the monitor a highly effective tool in face-to-face, across-the-table presentations, consultations, and the like.

The LL-S201A features a narrow 15.4-mm bezel and a “full-flat” screen that’s seamlessly flush with the bezel. This makes it ideal for touchscreen operations that involve swiping from the edge of the screen—for example, the charm bar in Windows® 8.

The LL-S201A weighs 2.3 kg and measures only 25.2 mm at its thickest point. This thin, lightweight design makes it easy to move about and enables users to easily switch between standing, pen writing, or horizontal usage styles.

The LL-S201A’s 20-inch-class LCD panel incorporates Sharp’s UV2A* technology. This ensures highly efficient use of light from the backlight and prevents light leakage, for the display of truly bright whites and extremely deep blacks. The LL-S201A also boasts 1,920 x 1,080-pixel full-HD resolution to ensure that none of the detail or visual impact is lost. Everything from fine text to intricate graphics is rendered with impressive precision.

* UV2A stands for “Ultraviolet-induced Multi-domain Vertical Alignment,” a photo-alignment technology that ensures uniform alignment of liquid crystal molecules.

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 next example is controlling an RGB LED using these three RGB sliders. For example if we start to slide the blue slider, the LED will light up in blue and increase the light as we would go to the maximum value. So the sliders can move from 0 to 255 and with their combination we can set any color to the RGB LED,  but just keep in mind that the LED cannot represent the colors that much accurate.

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.

As the code is a bit longer and for better understanding I will post the source code of the program in sections with description for each section. And at the end of this article I will post the complete source 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.

Next is the distance sensor button. First we need to set the color and then using the fillRoundRect() function we will draw the rounded rectangle. Then we will set the color back to white and using the drawRoundRect() function we will draw another rounded rectangle on top of the previous one, but this one will be without a fill so the overall appearance of the button looks like it has a frame. On top of the button we will print the text using the big font and the same background color as the fill of the button. The same procedure goes for the two other buttons.

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.

drawDistanceSensor(); // It is called only once, because in the next iteration of the loop, this above if statement will be false so this funtion won"t be called. This function will draw the graphics of the first example.

getDistance(); // Gets distance from the sensor and this function is repeatedly called while we are at the first example in order to print the lasest results from the distance sensor

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.

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.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work  you can check my particular tutorial. Here you can download that file:

drawDistanceSensor(); // It is called only once, because in the next iteration of the loop, this above if statement will be false so this funtion won"t be called. This function will draw the graphics of the first example.

getDistance(); // Gets distance from the sensor and this function is repeatedly called while we are at the first example in order to print the lasest results from the distance sensor

BCA and Brookfield have created the most advanced user experience in viscosity measurement by combining the ease of touch screen technology with the world-standard features of Brookfield’s series of DV-II Viscometers and DV-III Rheometers.

Brookfield is known for their superb work in mechanical design and production of their viscometers. Up until this point these designs included push button / character based LCD for the user interface. Brookfield came to us and wanted a modern color graphics LCD which would take their designs into the future. With a long list of requirements including touch screen technology and a tight deadline, BCA worked with the client to develop a program that established not only the right combination of electronics to drive their motor and torque analysis, but also a custom user interface. We had but one year to establish the product. We released the product on time. It was presented with great feedback at the Pittcon Conference 2013.

BCA worked on several pieces of the design in tandem to keep the project dates on target. The development of the electronics, firmware, and user interface occurred simultaneously. Additionally BCA was designing two models with different size touch screens and features. Code reuse was a must and the products today share the same compile.

There were some complex requirements on the electronics design. AD sample rates were specified in the 10 nanosecond range. The 7” LCD had specific speed requirements. The motor speed accuracy had to be 100%. We chose a Freescale IMX processor to handle the buck of this work. BCA has developed a royalty-free custom operating kernel which has been used in our product development for over 20 years. This finite state machine kernel was perfect for the over 200 states of this software. This allowed BCA to provide a royalty free option that already has support for system alarms, user interface screens with button input, event logging, protected memory access among many other modules.

BCA also has developed a custom tool that allows the user interface of an embedded system to be developed on a PC running Visual Studio. Hardware related events are simulated, thus the application engineers get to work out the user interface issues while providing the client’s marketing department a visual of exactly what the UI looks like. In this case, many user interface requirements were defined and redefined using this SimGUI, well before the first hardware board was fabricated. All this code was written in ’C’, thus it ported directly to the target hardware.

The final product redesign enhanced the ease of use with adding popular features. DV-III has real-time on screen graphing that can be saved to the device, printed directly from the device, or viewed on a PC. Built into the system are math models that can provide rapid data analysis for selectable variables. Data can be transferred via flash drive or a computer can be hooked up directly.

4 styles of diverse fashion design are optional in the interactive touch kiosk. Users are allowed to choose a suitable style to satisfy their own requirements. As a touch screen LCD display and LCD Interactive screen, this INDOOR INTERACTIVE TOUCH KIOSK-IK110 are supported great functions of the high compatible system and wayfinding application solution, which is going to fit in the shopping mall, office block, and hospital beautifully, looking to prevent complicate procedures for clients.

This IR touch screen is developed to offer convenience for users via its unique function of interface including the 10 points touch and IPS displays. Furthermore, its impeccable smooth radian is suitable for the tremendous super market whose location is a high-end line.
