Choose Right Interactive Display for Classroom

Whole-class learning is a key aspect of the modern classroom, but how do you find the right solution for your school? There are a variety of options, this article will talk about how to choose the right display for your classroom.
1. LED & LCD
All displays are LCD; they are backlit by LEDs or CCFLs. LED backlighting provides a brighter picture and is more energy-efficient. Don’t strain your brain over the acronyms – LCD/LED tends to be the better choice.
2. Screen Size
There are several screen sizes for choice in each LCD touch panel series. Students should be able to easily read 20-point type from the farthest point away from the display in the classroom. To make that determination, use this simple equation: 3X the diagonal screen size = the farthest distance from which a student can easily read the text on the display. A 70 in. display can thus serve students as far away as 17.5 ft (5.3 m), and an 84 in. display can serve students as far away as 21 ft (6.5 m). 
3. Multiple ports for external connection
Certain connections must be a given for your display to transmit and receive the necessary data effectively. For example, 2 HDMI, 1 VGA, a stereo connection if you are using VGA, and a microphone port if you will be using a microphone.
4. Multi points touch
 To find out how many touch points you need, ask yourself these two questions: How many students will I typically have working at the display? How many students can comfortably work at the display at the same time? 
5. Software
 Make sure that the software that comes with it gives you more than drivers and a slide show. You want to select software that can actually enable and engage learning – software that offers collaboration opportunities, provides assessment, and integrates with mobile learning.

The projector projects the computer’s desktop onto the board’s surface, where users control the computer with a pen, finger, or other device. The board is typically mounted to a wall or floor stand.
