How to clean a touch screen correctly and why you should avoid window cleaner

If you use a touchscreen regularly, you can hardly avoid dust, dirt and grease marks. When removing dust or fingerprints from your last contact with your touch screen, you should pay particular attention to using the right cleaning agent and correctly dealing with it.

Modern touch displays are brighter, sharper, more reactive , and are actually very robust against scratches. They at risk of the most danger when cleaned the wrong way – it can happen very quickly, and before you realize it, your touchscreen is damaged forever.

Correct cleaning does not cost much. So, you can save your touch screenfrom an untimely end.

What should you avoid when cleaning the touch screen?

  • Never apply the cleaning liquid directly onto the screen. Touch screens are manufactured from fine materials and glass – layer by layer. If you directly spray the cleaner onto it, the liquid can penetrate into the corners and then between the thin layers, causing large black spots on the touch screen. Although over the course of time they can become smaller, they will never disappear completely.

  • Never use paper towels or a multipurpose cleaning cloth. The surface of a paper towel is still too rough and causes abrasions. Cleaning with a traditional cloth can cause stains and scratches on the touch screen. A multipurpose cleaning cloth with which someone has cleaned a lunch table can cause devastating damage even from minimal residue left on it.
  • Never use alcohol or ammonia-based cleaning detergents! Touch screens usually have nice shiny surfaces covered with anti-reflex coating. By cleaning with aggressive chemicals, this layer will be removed – this can result in cloudiness and malfunctions, such as the reduction of capacitive properties of the touch screen.

How to clean the touch screen correctly?

    1. First, the touch screen should be prepared for cleaning. Turn off the screen and, preferably, disconnect it completely from any power sources. Clean the touch screen only when it has cooled down.
    2. A dry micro-fibre cloth is ideally suited for removing dust from touch screens, since it does no harm to the surface of the screen. Clean the touch screen with slow and gentle movements – never circular movements!

    3. The next step is to moisten the micro-fibre cloth with distilled water or a special screen cleaning agent to remove adherent dust and dirt. Do not use tap water: it usually always contains mineral deposits that can leave traces on the touch screen. A second cleaning with a dry cloth is not necessary.
    4. In a simple and low-cost way, you can avoid scratches, surface damage and after-clean cloudiness on your valuable touch screen. The special screen cleaning agent is much cheaper than a new screen and usually enough for many cleanings.

What your touch screen is cleaned with must not be left to chance! Better you procure the right cleaning agent (a set consisting of a cloth & fluid for each screen to be stored in the same room) beforehand so that you can enjoy your touch screen for a long time to come.

The perfect presentation – Touch screens against boredom

“More than 80 percent of all presentations are boring or even soporific.”

The Wall Street Journal recently came to this shocking result. Only 3% of the presentations held in companies inspire listeners and viewers, attract attention and thus contribute to simplifying work in the first place. There are multiple reasons for this. Often, there is simply fear of modern presentation technology behind it.

With some exercise, a children’s game

Presentations and meetings are intended to define project objectives, to coordinate project partners and improvetheir collaboration in the company. Overloaded slides, a monotonous lecture style as well as a lack of know-how on the touch screen often make a presentation a disaster only after a short time.

Before you begin with your presentation on the touch screen at all, you should ask yourself: Are my slides designed simply and attractively? Am I able to speak as freely as possible? Am I familiar with the touch screen? If you have to answer even one of these questions with “no”, this means: Practice makes perfect!

present at the touch screen - the perfect presentation

Here are some more general tips:

  1. Communicate only one message per slide. Not all people are multitasking. If your audience is constantly busy with reading, no one will listen to you.
  2. Do not read from your presentation slides and never turn your back on your audience. Maintain eye contact and respond to feedback from your audience.
  3. Use your touch screen as a resource for entertaining, interactive presentations. Reduce your stress factor by acquainting yourself with the technology and practicing with your touch screen.

How-to: Presentations o the touch screen – Part II

How to best display your content on the touch screen

About 30 million presentations are held around the world every day. Of these, 90% are considered to be boring and uninteresting “time wasters” for spectators or listeners. Therefore, not infrequently, a tormented groan from the workforce of a company is likely to occur when a presentation is announced for the next meeting: Stupidly designed slides with hardly readable contents, incomprehensible explanatory attempts, no possibility of active participation. It is unimaginable, how much time and money thereby is at stake for companies. InFocus donates you precious working hours: We show you how every presentation with a touch screen will become a success!

Touch screen devices from InFocus

InFocus is one of the market leaders for visual communication. For what reason? Because our innovative solutions, also in the field of touch display, always set new standards. Our touch screens JTouch, Mondopad and BigTouch enable presentations, video conferences and digital signage at the highest level.

Tips and tricks for a presentation with the InFocus touch screen which remains in the memory

Tips and tricks for a presentation which remains in the memory

Getting the best out of collaboration through simple communication, creating content, saving and sharing – with a touch-screen model from InFocus, you captivate your audience! Even external employees can participate in a presentation, whether connected via their own PC, the tablet or the smart phone.



Thanks to a wide range of connection facilities, such as HDMI, VGA and USB interfaces, the InFocus touch screen PCs offer versatile connectivity. Whether the interactive Mondopad touch PCs in full-HD and with integrated Windows computer as well as a collaboration suite, the Full HD BigTouch devices with integrated Windows 8 computer or the full-HD JTouch series for interactive digital signage with precise touch screen technology – InFocus makes presentations the popular must-do on the to-do lists.

In order to make your presentation on the touch screen a success, you should consider the following:

  • No false start: Forget the sneaky introductory sentences like “Today I am holding a presentation on the subject of xy.” You will be captivating your colleagues from the start with an exciting introduction to the topic.
  • Talk freely instead of reading: Anyone who reads a pre-written presentation word for word must reckon with a small attention from the audience. A monotonous lecture has a soporific effect and often prevents the release of one’s own thoughts.
  • Do not forget your body language. Communication works on several levels, the body language accounts for about 55% of the effect. Take full advantage of this potential.
  • Observe the font size: Your presentation might not only fail with overloaded slides, but also with a too small font. Often, the audience is able to see the text on the touch screen but not to read it. Especially for smaller touch displays, this is an important point that must be observed.
  • With the back turned to the touch screen: Your presentation will become a success, if the audience spellbound will hang to your every word. For this reason, position yourself with your back turned to the touch screen.
  • Active presentation style: What has been worked out together will remain in the memory. Make use of the possibility of annotating directly during the presentation and send the content in the appropriate format to the audience already during the event.
  • Multimedia content has a loosening-up effect: The audience becomes more attentive through videos. Something is happening. Anyone who visualizes the content of his presentation with a video will notice how quickly he will be back in the center of attention and interest in his presentation will be increasing.

How-to: Presentations on the touch screen – Part I

How to use the touch screen correctly

Clicking with the mouse, typing with the keyboard. This is what we have been used to for decades. The new generation of computers, smart phones or displays rely on the touch screen as the control element. But one touch screen is not the same as others. There are different types of touch displays with different functions, which can be operated individually. What is to bear in mind when using a touch screen with a finger? What kind of operating errors are lurking? How does the application with a pen work?

The capacitive Touch Display

capacitive touch screen - how to use it

capacitive touch screen – how to use it

Capacitive touch screens determine the position of the touch by changing an electric field. Electrodes in the corners of the touch panel produce a weak electric field. If at least one finger touches the touch screen, a part of the charge of the field is derived. Thus, the electric field will change. This change will be measured and the exact position of the finger will be determined in this way. Most of the InFocus devices work with this technique, which translates touches even more precisely, than resistive touch screens.

Touch screens offer advantages in application

Creating and moving texts, editing pictures and playing videos, all of this may be handled more easily with a touch screen than with a regular PC, because the computer mouse and the keyboard only function properly on the desk. The users of touch screens ave space in the workplace and also additional hardware costs.

tapping, rotating, contracting, wiping, zooming and turning by finger -easy and comfortable

No matter whether Mondopad, BigTouch or JTouch, our displays all are equipped with touch screen displays. We have optimized applications such as adding, activating, or removing documents for touch screen operations. The products of InFocus operate with the familiar multi-touch gestures, such as tapping, rotating, contracting, wiping, zooming and turning by finger or stylus pen. This makes the operation very easy and you receive an overview of all program windows similar to the Mission Control view. This allows users to navigate easily between different programs.



Our tips for easy operation:

  • Test each touch screen before using it in a presentation.
  • Practice: click, double-click, and swipe. Anyone who knows his touch display reduces the stress factor.
  • For some applications, finger operation is not sufficient. Use a stylus pen as an additional control element.
  • Work intuitively. Interaction with your content is easy and intuitive when using InFocus devices.

Field tested: The Mondopad in use at the Portland State University

In search of a high-tech collaboration solution for their students, researchers and other interest groups, the Portland State University tested the Mondopads of InFocus. Four years ago, with the development of the Mondopad InFocus created a solution for the large-scale visualization of data and images that also combines single and group work as well as video conferencing in a single device. This has a positive impact on research and teaching: cooperation and decision-making beyond local university boundaries. It is not without reason that the State University of Portland named the work space which is equipped with the Mondopads, their “Theater of decisions”.

Goals and wishes of the state university of Portland to the collaboration solution

The Portland State University has set itself the goal of driving the interlinking of research and teaching. Closer collaboration between research and authorities makes it possible to recognize recurring patterns through the large-scale data visualization and to make forecasts or future events. These results are applicable in areas such as prediction and prevention of environmental disasters.

At the University for Urban and Public Affairs, the Research Director describes the initial situation: „Originally, we only intended for different interest groups to be able to use a multi-part video wall in order to cooperate with each other.“ For this purpose, single display solutions have already been installed and tested, because „we have found that the individual displays open up new perspectives for our entire research area.“ In order to implement the desire for a cooperation space, the state university of Portland relied on the Mondopads of InFocus. They strove for a room with great visualization capabilities, powerful computers, robust video conferencing capabilities, and a collaborative, modular environment.

The Mondopads convinced through their complete offer consisting of touch screen, large format screen and video conference solution. „We have integrated them in different locations on the campus and are now benefiting from the ability of the Mondopads to bring together people from different areas.“ For the forest fire prediction and prevention sector, this means, for example, that a community resource has been created that may be used by many regional actors, such as first responders, in order to predict fire hazards and react as quickly as possible.

Fulfilling wishes by integrating Mondopads

Under the name „Theater of Decisions“ a work space was created, following the example of similar rooms at the Arizona State University and the University of Chicago. Thanks to the Mondopads, users can expect an immersive multimedia experience that encourages the independent work of individuals as well as cooperation in groups – and both within the university walls and beyond. The large-format touch-screen PCs make working very easy: Viewing and saving ideas in real-time, integrating external project workers, and providing versatile connectivity for individual use and an interactive touch screen experience.

The technical implementation in detail: Seven Mondopads in one room

The original idea of a multi-panel video wall was a headache for the technical service team at the university yet before the start of the project. Their preoccupation was that such a video wall would not provide sufficient flexibility and modularity to support individuals and groups equally in their work. However, since they had already successfully integrated some touchscreen displays in different training rooms years ago, they were confident.

The solution came from InFocus in the form of a modular, collaborative environment: the Mondopad. It facilitates a large-scale 360-degree view of various data and images as well as working on small units or small data sets. With the product line Mondopad, the Portland State University created an active learning environment. Touch screen interface, camera function and powerful speakers of the InFocus display solution are also convincing thanks to the compatibility with already used software on the part of the university.

The front of the “Theater of Decisions” workplace is tiled with three 80-inch Mondopads, which are capable of selectively displaying several small images or a giant image. On the remaining three walls, the technical service team installed four 70-inch Mondopads in order to support group work. The final result is a high-performance and multi-purpose space that enables researchers and community members to visualize data, collaborate with teams inside and outside the campus, and work individually in an uncomplicated manner.
