    Ideas before buying a touch panel display that meets your needs perfectly.

    Touch panel display technologies

    touch panel displays have passed several stages of manufacturing before reaching their final state today. Touch panel displays use three kinds of technologies: capacitive technology, infrared technology, and DViT technology.

    Capacitive technology is used to zoom an image on a smartphone or tablet with a simple touch. A transparent glass plate is this technology, and its operation depends on a small screen.

    While an interactive infrared touch screen has a standard monitor with a very variable size, these infrared emitting and receiving cells that eradicate across the screen surface produce an entirely light ray combination. Infrared technology provides bright displays, and there is less risk of damage from use due to its strength and durability. However, it cannot be used with a stylus or a gloved finger.

    Finally, DViT technology is an optical detection technology. It is roughly the same grade as infrared. This system is the most used of Smart Technologies with its SmartBoard ranges. Its command is executed thanks to its location and with the help of software very quickly. DViT “multitouch” determines a pure and simple touch. On the other hand, which differentiates it from infrared technology, its contact can be made even with a gloved finger or a stylus, and it offers excellent image resolution.

    How can you choose the touch panel display that best meets your needs?

    This is not an easy task, as there is a lot of intrusive advertising and incomprehensible jargon. So follow our guide to buying the best touch panel display for your classroom.

    We have identified ten criteria to take into account that will help you choose your touch screen:

    1) THE SIZE OF THE INTERACTIVE SCREEN

    The size of the room intended to receive the screen must influence the size of your screen. The rule of thumb is that the screen should be large enough to allow everyone to scan a 20-point font.

    55″ to 98″ but the most common sizes range from 65″ to 86″.

    Be careful, however, of the potential weight of some interactive screens. These weigh from 38 kg to more than 100 kg in some cases. It is necessary to take precautions in advance in terms of logistics and the nature of the wall so that the installation is done in certain conditions.

    2) DISPLAY RESOLUTION

    The higher the resolution, the more precise the image. Resolution is the number of pixels contained on the screen. Resolution is defined as the number of pixels on the horizontal X-axis and the vertical Y-axis.

    You need to consider which PC you will be using to drive these interactive displays. If that computer’s graphics capability is less than 1080P HD, you will only display in that lower resolution on your new interactive display.

    Most interactive displays are now available in Ultra High Definition, called 4K (3840 × 2160 pixels). You need to make sure you have a high-end computer with a 4K graphics card if you want to take full advantage—the 4K display of your interactive screen.

    3) THE SERVICE LIFE

    There are many interactive displays offering displays in the market, and therefore new brands are starting to take their place in this field. It is always helpful to know the lifespan of the interactive display you are considering purchasing and the warranty terms.

    Any good brand touchscreen should last for 50,000 hours of use, which will far exceed 15 years in a general environment.

    As for the warranty, conditions for these screens can range from 12 months with a return to workshop warranty up to 7 years with uninstallation and reinstallation on site.

    4) THE TACTILE SENSATION

    One of the main reasons to buy an interactive display is to be able to touch the screen and perform tasks through gestures.

    But not all screens have soft touch or even the ability to recognize different touch sources. For example, some interactive displays can only work with a stylus. At the same time, other more comprehensive systems can differentiate between pen touch and finger touch, with some even recognizing specific hand gestures for specific purposes. Specific tasks such as erasing with the wave of the hand.

    In addition to that, it can manage multiple touch points simultaneously. Most interactive touch screens are available with 6 or 10 simultaneous touchpoints.
