Interactive Touch Panel versus Interactive Projector

Over the last five years’ interactive projectors have been taking over from the IWB/Projector combination. With the dual pen Epson 585Wi and the multi touch Epson 595Wi, it has never been cheaper to add an interactive display solution or replace an old one in a classroom at around $3000 fully installed, including SMART Notebook15 software and a usual image size of 90”.

But what about LCD touch screens? The price of these interactive panels have come down to the same price as the original IWB/Projector combo.

So which should you choose for your classrooms? It depends on a range of factors and each school and each classroom will have different requirements that will favour one product over another. Here are a couple of things to consider.

LCD panels are generally brighter, have higher contrast and higher resolution. LCD Panels have a longer lamp time of over 50, 000 hours and an expected working life of between 5 and 10 years. They are also around twice the price of a projector at a smaller display size of 55” to 70” diagonally. To give you an idea on size the small IWB’s installed in schools were around 78”

Size is really important. We have worked with a school who put in 55” LCD panels through another supplier. They are now replacing them with interactive projectors because the LCD screens were too small for students to see text and graphics. A costly mistake, especially when they had to make special secure cupboards as the screens were a targeted by thieves when they were first installed.

The current minimum recommended size for a LCD panel in a standard classroom is 65” with a recommended size of 70” to 80”.

Another thing to consider is installation. Both of these options require a decent structure to install on. An interactive projector is around 22kgs including the mount. An interactive touch panels can be up to 55kg for a 70” version plus whatever mounting system you choose, so some walls will have to be braced. In some classrooms your only option is a trolley.

When upgrading your interactive technology look at all your options as well as the physical limitations of each solution. You may find each classroom will have a different solution.

Great post. I have an interactive LCD in my new room. I love it. The one thing I love is that it is mobile, on wheels. Its key because a mobile IWB is a challenge with alignment. The LCD panel eliminates that. It also lets me quickly switch from whole group to small group.
