Her ne kadar Türkiye’deki liseleri bir kısmına Etkileşimli tahtalar takılmış olsa da halen bir çok lise, ortaokul ve ilkokul da etkileşimli tahta yok. O sebeple projeksiyon cihazları birçok kurum için halen revaçta. Yeni nesil projeksiyon cihazlarında da teknoloji tabiki yerinde saymıyor. 20000 saatlik lamba ömürleri ve 1920×1080 Full HD destekleri ile ön plana çıkmaktadırlar. Tanıtımını yaptığımız Panasonic PT-RZ470 Projeksiyon cihazı da tüm güncel yenilikleri barındırmaktadır. Teknik özellikleri ise aşağıdadır.
