With all the advantages and disadvantages, lcdds are essentially a good choice for those who see the TV starting from 4k smartphone. Nowadays, in addition to the wholesale models, lcdds are essentially a good option for those that don ’ t have the capacity of a device.

Searching for the best and brightest large touch screen monitor for your office? Sounds like someone got an increase in their A/V budget. We’re not surprised, seeing as employee experience and self-service tech is a hot topic these days, with a 2017 Deloitte study stating that almost 80 percent of executives believe it’s important to very important. One way to improve employee experience is with transparency and visibility. Large-format touch screen displays showing interactive office maps in your lobby, kitchen, and elevator bay, for example, accomplish just that.

For the best-case scenario when employees interact with a large format touch screen display in your office, we recommend looking for these qualities to make for a quick, easy and accurate experience.

• Multi-touch vs single-touch:if you’re looking to use software that has zoom capabilities (like Robin interactive maps), you want to look for multi-touch displays. These could also be good for large-format displays where multiple people may be trying to click around, or if the software has any added multi-touch functionality (similar to Apple’s trackpad two-finger scroll or page flip motions).

• 5-wire resistive or infrared touch screens:Between the two, they cover the best circumstances for touch screen technology from transmissivity, type of object able to be used (stylus vs. finger), and more.There are technically five different types of touch screen technology, which you can read more about here.

We made a quick list of five the best touch screen options for your office lobbies and elevator bays. At Robin, we’ve tried out both Chromebase and Elo touch screen displays, both being solid options as they’re relatively easy to mount and setup. We also pulled some favorites from across the web.

Pros:Many format and size options, from seamless to matrixed video walls to simple large format touch screen displays. Includes infrared and multi-touch options.Cons:They seem to be expensive (but, you get what you pay for, if you’re looking for a 70” display or an entire wall)

You’re in luck. A fair amount of the larger format touch screen technology we’ve seen works with a standard TV. Seems like the industry recognizes it’s worth reusing a standard TV and simply making it touch-enabled with an overlay “frame” of sorts. Here are a ton of size options for infrared, multi-touch overlays from OPTIR via Tyco Touch.

An ideal office scenario would be to have a large-format touch screen monitor in your lobby and on each floor in the elevator bay or kitchen areas. These are often the highest-trafficked collision points in an office and therefore the places where employees would greatly benefit from seeing an interactive map and schedule of the workplace.

As your company grows, you’ll want to keep up the pace of strong internal communications and visibility. Large-format displays, especially touch screen ones, help you accomplish this objective really easily.

From wayfinding and conference room booking to internal communications of all types, having touch screens in high-traffic locations will make you look like the office admin superstar you really are. You could welcome new hires, tell everyone about a new product, or roll out a brand new software tool (like Robin) via these screens.

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.

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.

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.

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’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.

For example, on a device that is stable at a single touch, it is also easy to check the phenomenon becomes unstable when it comes to three or more points.

As the world returns to the office — at least in some capacity — one of the biggest concerns that companies have is ensuring that a given work set-up keeps employees safe, connected, happy, and effective at doing their work. What an office setting will look like will vary greatly, however, it is becoming more and more accepted that work is not a place you go, it"s a thing that you do. And as such the work-from-anywhere environment will become increasingly more common.

Because of this, touchscreen displays will play an important role in allowing digital collaboration between hybrid teams to continue in a seamless way. Up until a few years ago, touchscreens were clunky devices that were too complex and difficult to use. But improvements in the accuracy of the touch interface have enhanced the user experience greatly. You can now use them with the familiarity of your personal touch devices.

There are a number of great reasons for using digital devices in your sessions, but choosing which touchscreen display to get is not that straightforward. The touchscreen display market is becoming increasingly crowded with many different brands, screen technologies, sizes, and extras to choose from. And more importantly also the space, software, methods, and people need to be taken into account before such an investment is made.

For a smooth MURAL experience we recommend using a good graphics card and at least 8GB of RAM (but preferably 16GB of RAM). This will make sure the touch experience is smooth.

Try quick drawing and moving sticky notes in MURAL to see how the latency (delay) of the screen is. The less latency the better, as we’ve seen screens not being used because of their high latency.

By asking yourself each of the questions below, you can make sure that you are making an investment in a touchscreen display that will allow your hybrid, remote, and in-person teams to collaborate effectively.

Start with the question: what is the main purpose and use case for this touchscreen display? Too often we have seen touchscreens collecting dust because the purpose for using it wasn’t clear from the beginning.

Work here is often done in break-out groups of five to eight people where they will work on one screen to solve a problem using a variety of techniques. This set-up is very flexible and groups are often moved around different areas of the space. Touch experience, multi-touch (allows multiple people to work on the screen at the same time) and movability of the device are very important here. The screen size can also be a bit smaller. For instance, you can even do breakout group work on a 27” touchscreen monitor set up on a hightop table.

The only person interacting with the screen will be a presenter or facilitator, to display their presentation, synthesize work and make annotations. The larger the screen the better here. Sometimes it is even connected to a large projector for bigger groups. Multi-touch experience is not crucial. And the screen might be in a fixed position.

Touchscreen displays typically come in screen diameters of 55”, 65”, 75” and 85”. But also 27” touchscreen monitors such as the Microsoft Surface Studio could work well.

If we bring this back to the use cases mentioned earlier, break-out sessions in innovation labs are often best served by a 55-65” screen, but the 27” Microsoft Surface Studio on top of a high table works just as well. For presentation rooms you would almost always need to go for the largest screen size, or even connect it to a projector with a larger screen size. And meeting rooms could best use a 55-75” screen, depending on the size of the room.

We’ve seen large touchscreen displays mounted to a wall in a meeting room where it was just being used for screen sharing like a normal TV screen. You want to avoid that.

The advantage of having the screen on a rolling stand is that its users will be able to work in the best places to support whatever task is at hand. It allows people to be more agile and creative. Which is essential for teams in innovation labs. But it can also provide more flexibility to meeting and presentation rooms, as you are likely not going to equip every single room with a touchscreen display.

Reasons for why touchscreen displays are fixed to a wall are because of saving space and aesthetics. But also IT might not want to have expensive equipment moving around. And the extra cost of a rolling stand might weigh in sometimes too.

Next to a big screen on a rolling stand, a smart projector like Adok is an interesting solution to provide a touch ‘screen’ in a portable format, that can be set up anywhere.

OPS PC’s are shipped with every Operating System PC’s can have and are usually the norm for corporate clients, for example to run Windows 10 that is standard across other devices. Next to that these PCs are added to have more power in order to run more advanced software and have a better touch experience. Just like built-in PCs these can be set up both in PC/Desktop or Kiosk mode.

This is a new concept for touchscreen displays that is gaining popularity recently. Here the display is basically just an empty screen without any operating system. You just connect your own device to make use of the screen. It’s plug & play to project your device’s display on the big screen and use its touchscreen to control. This has two advantages. No worries for IT because there is nothing to secure on the touchscreen display. And ease of use for the user because they know very well how to operate their personal device.

The Microsoft Windows Collaboration Displays developed by Avocor and Sharp are great examples of this. But you can essentially connect your personal device to any touchscreen display. You can for example connect your device running Windows 10 to a Samsung Flip (that has an Android based OS) to run the apps you need.

Some touchscreen displays come with webcam and microphone integrated. Others are easily upgradeable with a camera plus microphone such as the Huddly. Both of these options work great when collaborating with a smaller team close to the screen.
